Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

 

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with:

 

In addition to historical information, this discussion and analysis contains forward-looking statements that are subject to risks and uncertainties, including those discussed in the section titled “Risk Factors,” set forth in Item 1A of our Form 10-K and this Form 10-Q, that could cause actual results to differ materially from historical results or anticipated results.

 

Overview

 

We are a biotechnology company focused on developing advanced therapies for autoimmune and inflammatory diseases involving the complement component 5 (“C5”) and leukotriene B4 (“LTB4”) pathways. Each of these pathways has scientifically well-supported causative roles in the diseases we are targeting. We believe that blocking early mediators of inflammation will prevent initiation and continual amplification of the processes that cause certain diseases. Our activities since inception have consisted of performing non-clinical and clinical research and development activities and raising capital.

Our lead product candidate, nomacopan, is a recombinant small protein (16,769 Da) derived from a protein originally discovered in the saliva of the Ornithodoros moubata tick, which modulates the host immune system to allow the parasite to feed without alerting the host to its presence or provoking an immune response. Nomacopan is a second-generation complement inhibitor which has been shown to act on complement C5, preventing release of C5a and formation of C5b-9 (also known as the membrane attack complex (“MAC”)). Nomacopan also specifically sequesters and inhibits LTB4. Complement C5 and LTB4 activation and their proinflammatory actions are typically co-localised during an immune reaction. With its unique bispecific mode of action and biophysical properties, we believe nomacopan may be able to prevent inflammatory and prothrombotic activities of these two important pathways and also and has the potential to be formulated for administration by a variety of routes including subcutaneous, intravenous, topical to eye, inhaled and intravitreous.

We are investigating PAS-nomacopan, a long-acting form of nomacopan that is a bispecific inhibitor of C5 and LTB4, for the intravitreal treatment of geographic atrophy (“GA”) secondary to dry age-related macular degeneration (“AMD”) in preclinical studies. Following a positive and constructive Pre-Investigational New Drug application meeting with FDA in August 2024, we are completing final non-clinical studies and Good Manufacturing Practices (“GMP”) manufacturing and expect to file an Investigational New Drug Application (“IND”) with the FDA in 2025 for PAS-nomacopan in GA. We believe PAS-nomacopan has the potential for longer dose intervals between intravitreous injections than currently approved complement only inhibitors, as well as potential reduction of the choroidal neovascularization (“CNV”) risk that is associated with approved inhibitors. CNV is a sight-threatening over development of blood vessels within the retina, which is typically treated with anti-vascular endothelial growth factor (“VEGF”) intravitreal injections. As a bispecific inhibitor of complement C5 and LTB4 we believe PAS-nomacopan may be more efficacious than marketed treatments for GA that only inhibit complement.

Until May 2024, we were conducting a clinical trial of subcutaneous nomacopan for the treatment of hematopoietic stem cell transplant-related thrombotic microangiopathy (“HSCT-TMA”) in pediatrics. Following completion of a portfolio prioritization review, we announced that our HSCT-TMA program will be suspended, as more fully described below.

Recent Developments

 

Pipeline Prioritization of the Merged Companies

In May 2024, we announced the completion of a joint portfolio prioritization review pursuant to which the anticipated combined entity, following completion of the proposed Merger (as defined below), will focus on Peak Bio’s antibody drug conjugate (“ADC”) platform technology and our PAS-nomacopan GA program. As a result, our HSCT-TMA program was suspended, with enrollment in our pediatric clinical study discontinued due to cost and timeline. Following the closing of the Merger on November 14, 2024, we have expanded our pipeline of assets spanning early and late development stages with the addition of Peak Bio’s ADC toolkit with novel payload and linker technologies as well as the Peak Bio PHP-303 small molecule selective and reversible neutrophil elastase inhibitor. The ADC program includes a novel pre-clinical ADC candidate targeting TROP-2. By combining chemotherapy with immunotherapy strategies, we aim to develop cutting-edge solutions for cancer patients. Further, related to PHP-303, we expect to emphasize partnering/collaboration and licensing opportunities with broad potential impact on patients. We also plan to work closely with the FDA to define the best path for this platform and will pursue opportunities for external partnering/collaboration and licensing for nomacopan, including as a potential treatment for pediatric HSCT-TMA.

Restructuring and Reduction-in-Force

In May 2024, we began to implement a reduction-in-force (the “RIF”) of approximately 67% of our total workforce, as a result of the recently announced program prioritization under which our HSCT-TMA program was suspended. The RIF is part of an operational restructuring plan and includes the elimination of certain senior management positions and was substantially completed by the end of the second quarter. The purpose of the restructuring plan, including the reduction-in-force, is to reduce HSCT-TMA related operating costs, while supporting the execution of our long-term strategic plan. For additional information, refer to the below discussion under the heading “Restructuring and Other Costs” and Note 2 to the notes to unaudited condensed consolidated financial statements included elsewhere in this Form 10-Q.

 

Merger Agreement

On November 14, 2024, we completed the previously announced strategic combination (the “Closing”) contemplated by that Agreement and Plan of Merger by and among Akari, Peak Bio, Inc. (“Peak Bio”) and Pegasus Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of Akari (“Merger Sub”) as amended by that certain side letter dated August 15, 2024 (the “Merger Agreement”), pursuant to which, upon the terms and subject to the conditions thereof, Merger Sub was merged with and into Peak Bio (the “Merger”), with Peak Bio surviving the Merger as a wholly owned subsidiary of Akari.

 

For additional information on the Merger and the Closing, refer to Note 3 and Note 10 to the notes to unaudited condensed consolidated financial statements included elsewhere in this Form 10-Q.

Research and development expenses

 

Our research and development expenses are charged to operations as incurred, and we incur both direct and indirect expenses for each of our programs. We track direct research and development expenses by preclinical and clinical programs, which may include third-party costs such as CROs, contract laboratories, consulting, and clinical trial costs. We do not allocate indirect research and development expenses, which may include product development and manufacturing, clinical, medical, regulatory, laboratory (equipment and supplies), personnel, facility and other overhead costs, to specific programs.

During the three months ended September 30, 2024, total research and development expenses increased by approximately $0.5 million, or 146%, as compared to the three months ended September 30, 2023. During the nine months ended September 30, 2024, total research and development expenses increased by approximately $2.8 million, or 95%, as compared to the nine months ended September 30, 2023. The following sets forth research and development expenses for the three and nine months ended September 30, 2024 and 2023 by category:

HSCT-TMA clinical development (AK901)

 

These expenses include external expenses that we have incurred in connection with the development of nomacopan for the treatment of pediatric HSCT-TMA and primarily consist of payments to CROs and other vendors. The $0.1 million, or 31%, increase in expenses incurred during the three months ended September 30, 2024 and $0.5 million, or 43%, increase in expenses incurred during the nine months ended September 30, 2024, each as compared to the corresponding 2023 period, is primarily due to changes in clinical trial status and related impact on direct service fees incurred with CROs and timing of investigator payments. While the increase for three months ended September 30, 2024 was primarily due to clinical trial close out costs, the increase for the nine months ended September 30, 2024 was also due to increases in patient enrollment and related clinical trial costs incurred during the first quarter of 2024, prior to suspension of the program. In May 2024, following the completion of a pipeline prioritization review, we determined to suspend our HSCT-TMA program. Accordingly, we expect future HSCT-TMA costs to decrease following completion of the wind-down and closeout of the clinical trial.

 

BP clinical development (AK802)

 

These expenses previously included external expenses that we incurred in connection with the development of nomacopan for the treatment of bullous pemphigoid (“BP”) and primarily consist of payments to CROs and other vendors. In 2022, we discontinued our BP clinical program and in connection with the final reconciliation of clinical trial close-out costs, we recorded a $1.1 million credit in 2023 and do not expect to incur material additional costs related to this program.

 

Chemistry, manufacturing and control

 

These expenses include external expenses incurred related to the development and manufacturing of nomacopan for use in clinical trials and preclinical development of PAS-nomacopan. Such expenses primarily consist of payments to CMOs and other vendors for manufacturing of drug substance (including raw materials), drug product, supplies, and validation, quality assurance and manufacturing development activities. The $0.3 million, or 42%, decrease in expenses incurred during the three months ended September 30, 2024 and $1.8 million, or 108%, increase in expenses incurred during the nine months ended September 30, 2024, each as compared to the corresponding periods in 2023, is primarily due to the timing of manufacturing and development activities, including decreases in spending on the development of and preparation for manufacturing of PAS-nomacopan during the three months ended September 30, 2024 as a result of the completion of PAS-nomacopan good manufacturing practice (“GMP”) drug substance manufacturing during the second quarter of 2024 which was the primary reason for the increase in costs during the nine months ended September 30, 2024, as compared to 2023.

 

Other external development expenses

 

These expenses include external expenses, such as payments to contract vendors, which may be related to preclinical development activities and other unallocated expenses. The $0.1 million, or 43%, decrease in expenses incurred during the three months ended September 30, 2024 and $0.6 million, or 44%, decrease in expenses incurred during the nine months ended September 30, 2024, each as compared to the corresponding periods in 2023, is primarily related to lower costs incurred related to preclinical studies and other development work investigating PAS-nomacopan for the treatment of GA.

Personnel costs

 

These expenses include compensation and related costs associated with employees, independent consultants and staffing firms. The $0.5 million, or 60%, decrease in expenses incurred during the three months ended September 30, 2024 and $1.2 million, or 48%, decrease in expenses incurred during the nine months ended September 30, 2024, each as compared to the corresponding periods in 2023, is primarily due to the impact of the RIF which was announced in May 2024, along with lower costs incurred with consultants. Separation benefits paid to impacted employees are classified separately under “Restructuring and other costs” as discussed below.

---

Tax credits

 

We record receipts of U.K. tax credits in the year received as a reduction in research and development expenses. Changes in tax credits received are the result of eligible research and development expenses incurred in the previous tax year, which can fluctuate depending on timing of and location in which expenses are incurred.

 

The extent of our future research and development expenditures will be determined based on future funding and closing of the Merger.

General and administrative expenses

 

During the three months ended September 30, 2024, total general and administrative costs decreased by approximately $1.1 million, or 39%, as compared to the three months ended September 30, 2023. During the nine months ended September 30, 2024, total general and administrative costs decreased by approximately $2.2 million, or approximately 25%, as compared to the nine months ended September 30, 2023. The decreases during both periods were primarily due to decreases in personnel costs resulting from the impact of the RIF which was announced in May 2024, along with lower costs incurred with consultants. Separation benefits paid to impacted employees are classified separately under “Restructuring and other costs” as discussed below.

 

Merger-related Costs

 

Merger-related costs consist of direct expenses incurred in connection with the proposed Merger and are comprised primarily of legal and professional fees.

 

Merger-related costs for the three and nine months ended September 30, 2024 were $1.0 million and $2.3 million, respectively. No such costs were incurred during the corresponding 2023 periods.

 

Restructuring and Other Costs

 

Restructuring costs consist primarily of severance and related benefit costs related to workforce reductions incurred in connection with the RIF, which the Company began to implement in May 2024.

 

Restructuring and other costs for the three and nine months ended September 30, 2024 were $0.1 million and $1.7 million, respectively, and includes $0.3 million of non-cash share-based compensation expense for the nine months ended September 30, 2024. No such costs were incurred during the corresponding 2023 periods.

 

Interest income

 

Interest income consists primarily of interest income received on deposits.

 

During the three and nine months ended September 30, 2024 and 2023, interest income was less than $0.1 million. Interest income may fluctuate from period to period due to changes in average cash balances and prevailing interest rates.

 

Interest expense

 

Interest expense primarily consists of interest incurred on the May 2024 Notes and in connection with the financing of director and officer insurance premiums.

 

During the three and nine months ended September 30, 2024, interest expense was less than $0.1 million and approximately $0.1 million, respectively. Interest expense may fluctuate from period to period due to changes in average interest-bearing loans and related interest rates. No interest expense was recognized during the three and nine months ended September 30, 2023.

Change in fair value of warrant liability

 

Change in fair value of warrant liability represents non-cash warrant revaluation gains or losses related to the remeasurement of our liability-classified September 2022 Warrants, as more fully described in Note 2 and Note 4 of the notes to the condensed consolidated financial statements appearing elsewhere in this Form 10-Q. Due to the nature of and inputs in the model used to assess the fair value of our outstanding September 2022 Warrants, it is not abnormal to experience significant fluctuations during each remeasurement period. These fluctuations may be due to a variety of factors, including changes in our stock price and changes in estimated stock price volatility over the remaining life of the warrants.

 

During the three months ended September 30, 2024, we recorded a change in the fair value of warrant liability, representing a non-cash warrant revaluation gain of less than $0.1 million, as compared to a non-cash warrant revaluation loss of approximately $0.3 million for the three months ended September 30, 2023. Changes in the fair value of the warrant liability and resulting warrant revaluation gain for the three months ended September 30, 2024 was driven primarily by decreases in expected term and expected volatility assumptions during the reporting period. Changes in the fair value of the warrant liability and resulting warrant revaluation loss for the three months ended September 30, 2023 was driven primarily by an increase in our stock price during the reporting period.

 

During the nine months ended September 30, 2024 and 2023, we recorded a change in the fair value of warrant liability, representing a non-cash warrant revaluation gain, of approximately $0.5 million and $5.9 million, respectively. Changes in the fair value of the warrant liability and resulting warrant revaluation gains for each of the nine months ended September 30, 2024 and 2023 was driven by a decrease in our stock price and decreases in expected term and expected volatility assumptions during the reporting period.

 

Foreign currency exchange gain (loss), net

 

During the three months ended September 30, 2024, we recorded a net foreign currency exchange gain of $0.1 million, as compared to a net foreign currency exchange loss for the three months ended September 30, 2023. During each of the nine months ended September 30, 2024 and 2023, we recorded a net foreign currency exchange loss of less than $0.1 million. Exchange gains and losses can fluctuate significantly from period to period due to changes in exchange rates as well as the volume and timing of expenditures and related payments denominated in foreign currencies.

 

Other expense, net

During each of the three and nine months ended September 30, 2024 and 2023, net other expense was less than $0.1 million and not material. Such expenses are not expected to be material to our future results of operations.

 

Net Loss Applicable to Ordinary Shareholders

 

As a result of the factors discussed above, net loss applicable to ordinary shareholders for each of the three months ended September 30, 2024 and 2023 was $2.9 million. Net loss applicable to ordinary shareholders for the nine months ended September 30, 2024 and 2023 was $16.0 million and $5.9 million, respectively.

Financial Condition, Liquidity and Capital Resources

 

Sources of Liquidity

Since inception, we have incurred substantial losses, and we have primarily funded our operations with proceeds from the sale of equity securities, including ordinary shares, warrants and pre-funded warrants, and convertible notes. At September 30, 2024, we had $2.2 million in cash and an accumulated deficit of $243.5 million. To date, we have not generated any revenue.

We have devoted substantially all of our efforts to research and development, including clinical trials, and we have not commercialized any products. Our research and development activities, together with our general and administrative expenses, are expected to continue to result in substantial operating losses for the foreseeable future. These losses, among other things, have had and will continue to have an adverse effect on our shareholders’ equity, total assets and working capital. Due to the numerous risks and uncertainties associated with developing drug candidates and, if approved, commercial products, we are unable to predict the extent of any future losses, whether or when any of our drug candidates will become commercially available or when we will become profitable, if at all. Our future capital requirements will depend on many factors, including:

 

 

We currently do not have any firm commitments for future external funding. We will need to raise additional funds, and we may decide to raise additional funds even before we need such funds if the conditions for raising capital are favorable. Until we can generate significant recurring revenues, we expect to satisfy our future cash needs through debt or equity financings, credit facilities or by out-licensing applications of our product candidates. The sale of equity or convertible debt securities may result in dilution to our existing shareholders. The incurrence of indebtedness would result in increased fixed obligations and could also subject us to covenants that restrict our operations. We cannot be certain that additional funding, whether through grants, financings, credit facilities or out-licensing arrangements, will be available to us on acceptable terms, if at all. If sufficient funds are not available, we may be required to delay, reduce the scope of or eliminate research or development plans for, or commercialization efforts with respect to, one or more applications of our product candidates, or obtain funds through arrangements

with collaborators or others that may require us to relinquish rights to certain potential products that we might otherwise seek to develop or commercialize independently.

 

November 2024 Private Placement

As discussed in Note 10 to our notes to unaudited condensed consolidated financial statements included elsewhere in this Form 10-Q, in November 2024, we entered into a purchase agreement with certain investors, pursuant to which we agreed to sell and issue in a private placement an aggregate of 1,713,402 ADSs, and warrants to purchase up to 1,713,402 ADS, at a per unit (each unit consists of one ADS and one warrant) purchase price of (i) $1.70 per ADS and warrant for all investors other than Drs. Patel and Prudo, and (ii) $2.385, which is equal to the consolidated closing bid price of the ADSs on The Nasdaq Stock Market on November 12, 2024 plus $0.125 for Drs. Patel and Prudo, for aggregate gross proceeds of $3.2 million.

 

May 2024 Private Placement

As discussed in Note 6 to our notes to unaudited condensed consolidated financial statements included elsewhere in this Form 10-Q, in May 2024, we entered into a purchase agreement with certain investors, pursuant to which we sold and issued in a private placement an aggregate of 4,029,754 ADSs, and warrants to purchase up to 4,029,754 ADS, at a per unit (each unit consists of one ADS and one warrant) purchase price of $1.885, for aggregate gross proceeds of approximately $7.6 million. Net proceeds from the May 2024 Private Placement were approximately $7.0 million after deducting placement agent fees and other expenses.

May 2024 Convertible Notes

As discussed in Note 2 to our notes to unaudited condensed consolidated financial statements included elsewhere in this Form 10-Q, in May 2024, we entered into convertible promissory notes with existing investors and directors, Dr. Prudo and Dr. Patel, for an aggregate of $1.0 million (the “May 2024 Notes”).

March 2024 Private Placement

As discussed in Note 6 to our notes to unaudited condensed consolidated financial statements included elsewhere in this Form 10-Q, in March 2024, we entered into a definitive purchase agreement with certain existing investors, pursuant to which we sold and issued in a private placement an aggregate of 1,320,614 ADSs at $1.48 per ADS, for aggregate gross proceeds of approximately $2.0 million. Net proceeds from the March 2024 Private Placement were approximately $1.7 million after deducting placement agent fees and other expenses.

Funding Requirements

 

As of the date of this report, we expect our existing cash, plus cash expected to be received from the November 2024 Private Placement to be sufficient to fund our operations into the first quarter of 2025. We do not currently have any products approved for sale and do not generate any revenue from product sales. We are currently seeking and expect to continue to seek additional funding through financings of equity and/or debt securities. We may also engage in strategic research and development collaborations, clinical funding arrangements, the sale or license of technology assets, and/or other strategic alternatives.

 

Financing may not be available to us when we need it, or on favorable or acceptable terms, or at all. We could be required to seek funds through means that may require us to relinquish rights to some of our technologies, drug candidates or drugs that we would otherwise pursue on our own. In addition, if we raise additional funds by issuing equity securities, our then existing shareholders may experience dilution. The terms of any financing may adversely affect the holdings or the rights of existing shareholders. An equity financing that involves existing shareholders may cause a concentration of ownership. Debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends, and are likely to include rights that are senior to the holders of our ordinary shares. Any additional debt or equity financing may contain terms which are not favorable to us or to our shareholders, such as liquidation and other preferences, or liens or other restrictions on our assets. As discussed in

---

Note 9 to the consolidated financial statements included in the 2023 Form 10-K, additional equity financings may also result in cumulative changes in ownership over a three-year period in excess of 50% which would limit the amount of net operating loss and tax credit carryforwards that we may utilize in any one year.

 

If we are unable to raise additional capital when required, or on acceptable terms, we may be required to:

 

 

Any of these events could have a material adverse effect on our business, operating results, and prospects.

 

We believe the key factors which will affect our ability to obtain funding are:

 

 

In addition, increases in expenses or delays in clinical development may adversely impact our cash position and require additional funds or cost reductions.

 

Based on our recurring losses from operations incurred since inception, our expectation of continuing operating losses for the foreseeable future, negative operating cash flows for the foreseeable future, and the need to raise additional capital to finance its future operations, we have concluded that there is substantial doubt regarding our ability to continue as a going concern within one year after the date that our unaudited condensed consolidated financial statements, included elsewhere in this Form 10-Q (such unaudited condensed consolidated financial statements, the “consolidated financial statements”) are issued. The accompanying unaudited condensed consolidated financial statements have been prepared assuming that we will continue as a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. As such, the accompanying condensed consolidated financial statements do not reflect any adjustments relating to the recoverability and classification of recorded assets and liabilities that might be necessary if we are unable to continue as a going concern.

Cash Flows

 

The following table summarizes our sources and uses of cash for each of the periods presented (in thousands):

 

		Nine Months Ended
		September 30,
(In thousands)		2024				2023
Net cash (used in) provided by:
Net cash used in operating activities		$	(10,428	)		$	(12,023	)
Net cash provided by financing activities			8,834				3,503
Effect of exchange rates on cash			(5	)			1
Net decrease in cash		$	(1,599	)		$	(8,519	)

 

Operating Activities. The net cash used in operating activities for the periods presented consists primarily of our net loss adjusted for non-cash charges and changes in components of working capital. The decrease in cash used in operating activities during the nine months ended September 30, 2024, as compared to the 2023 period, was primarily due to the net impact of deferrals of payables in order to preserve cash until additional capital is raised for working capital purposes, partially offset by an increase in operating expenses.

 

Investment Activities. There were no investing activities during the nine months ended September 30, 2024 and 2023.

Financing Activities. Net cash provided by financing activities primarily consisted of the following:

Material Cash Requirements

 

During the nine months ended September 30, 2024, there were no material changes outside the ordinary course of our business to our contractual obligations and cash requirements, as disclosed in our Form 10-K.

Critical Accounting Estimates

 

This management’s discussion and analysis of financial condition and results of operations is based on our condensed consolidated financial statements, which have been prepared in accordance with U.S. GAAP. In doing so, we must make estimates and assumptions that affect our reported amounts of assets, liabilities and expenses, as well as related disclosure of contingent assets and liabilities. On an ongoing basis, management evaluates its estimates and judgments, including, but not limited to, those related to (i) share-based compensation, (ii) fair value of warrants classified as liabilities, (iii) research and development prepayments, accruals and related expenses, and (iv) the valuation allowance for deferred income taxes. Management bases its estimates and judgments on historical experience and on various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

 

We regard an accounting estimate or assumption underlying our financial statements as a “critical accounting estimate” if:

 

There have been no material changes to our critical accounting policies and estimates since December 31, 2023. See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations — Critical Accounting Estimates” of our Form 10-K, for a discussion of significant estimates and assumptions made by our management as part of the preparation of this management's discussion and analysis of financial condition and results of operations and accompanying condensed consolidated financial statements.

 

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

 

We are a smaller reporting company, as defined by Rule 12b-2 of the Securities Exchange Act of 1934, as amended, and are not required to provide the information required under this item.

---

Item 4. Controls and Procedures.

Disclosure Controls and Procedures

 

Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of September 30, 2024. In designing and evaluating our disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and our management necessarily applied its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on this evaluation, our principal executive officer and principal financial officer concluded that as of September 30, 2024, our disclosure controls and procedures were (1) designed to ensure that material information relating to us is made known to our principal executive officer and principal financial officer by others, particularly during the period in which this report was prepared, and (2) effective, in that they provide reasonable assurance that information required to be disclosed by us in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the fiscal quarter ended September 30, 2024 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Nasdaq Compliance Update

On April 5, 2024, we received a letter (“Letter”) from the Listing Qualifications Staff (the “Staff”) of The Nasdaq Capital Market (“Nasdaq”) notifying us that our shareholders’ equity as reported in our Form 10-K was not in compliance with the minimum shareholders’ equity requirement under Nasdaq Listing Rule 5550(b)(1), which requires listed companies to maintain shareholders’ equity of at least $2.5 million (the “Shareholders’ Equity Requirement”). In accordance with the Nasdaq Listing Rules, on May 20, 2024, we submitted a plan to regain compliance with the Stockholders’ Equity Requirement (the “Compliance Plan”) for the Staff’s consideration. On August 5, 2024, we were notified by the Staff that we had been granted an extension until September 30, 2024 to comply with the Compliance Plan and evidence compliance with the Shareholders’ Equity Requirement. On October 1, 2024, we received a delisting determination letter (“Delisting Determination Letter”) from the Staff notifying us that we did not meet the terms of the extension. On October 8, 2024, we requested a hearing before the Nasdaq Listing Qualifications Panel to appeal the Staff’s delisting determination.

On November 18, 2024, we received a letter from the Nasdaq Office of General Counsel notifying us that we have regained compliance with the Shareholders’ Equity Requirement. While we have regained compliance with the Shareholder’s Equity Requirement, we cannot guarantee that we will maintain compliance with this requirement and the other continued listing requirements of Nasdaq.

Description of Business	9 Months Ended
	Sep. 30, 2024
Description of Business
Description of Business	Note 1. Description of Business Business Overview Akari Therapeutics, Plc, (the “Company” or “Akari”) is incorporated in the United Kingdom. The Company is a biotechnology company focused on developing advanced therapies for autoimmune and inflammatory diseases involving the complement component 5 (“C5”) and leukotriene B4 (“LTB4”) pathways. The Company’s activities since inception have consisted of performing research and development activities and raising capital. The Company is subject to a number of risks similar to those of preclinical stage companies, including dependence on key individuals, uncertainty of product development and generation of revenues, dependence on outside sources of capital, risks associated with preclinical trials of products, dependence on third-party collaborators for research and development operations, need for marketing authorization of products, risks associated with protection of intellectual property, and competition with larger, better-capitalized companies. To fully execute its business plan, the Company will need, among other things, to complete its research and development efforts and clinical and regulatory activities. These activities may take several years and will require significant operating and capital expenditures in the foreseeable future. There can be no assurance that these activities will be successful. If the Company is not successful in these activities it could delay, limit, reduce or terminate preclinical studies, clinical trials or other research and development activities. Merger with Peak Bio As further described in Note 10, on November 14, 2024, the Company closed the previously announced merger with Peak Bio, Inc. (“Peak Bio”). As a result, the Company expanded its pipeline of assets spanning early and late development stages with the addition of Peak Bio’s antibody drug conjugate (“ADC”) toolkit with novel payload and linker technologies as well as the Peak Bio PHP-303 small molecule selective and reversible neutrophil elastase inhibitor. By combining chemotherapy with immunotherapy strategies, the Company aims to develop cutting-edge solutions for cancer patients. Liquidity and Financial Condition The Company follows the provisions of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 205-40, Presentation of Financial Statements—Going Concern, which requires management to assess the Company’s ability to continue as a going concern within one year after the date the consolidated financial statements are issued. The Company has incurred substantial losses and negative cash flows since inception and had an accumulated deficit of $243.5 million as of September 30, 2024. The Company’s cash balance of $2.2 million as of September 30, 2024 is not sufficient to fund its operations for the one-year period after the date these condensed consolidated financial statements are issued. These factors raise substantial doubt about the Company’s ability to continue as a going concern. The accompanying condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The condensed consolidated financial statements do not include any adjustments related to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of this uncertainty. The Company anticipates incurring additional losses until such time, if ever, that it can generate significant sales of its product candidates currently in development. The Company is subject to a number of risks and uncertainties similar to those of other companies of the same size within the biotechnology industry, such as uncertainty of clinical trial outcomes, uncertainty of additional funding, and history of operating losses. Substantial additional financing will be needed by the Company to fund its operations and to commercially develop its product candidates. Management is currently evaluating different strategies to obtain the required funding for future operations. These strategies may include, but are not limited to: product development financing, private placements and/or public offerings of equity and/or debt securities, and strategic research and development collaborations and/or similar arrangements. There can be no assurance that these future funding efforts will be successful. Nasdaq Continued Listing Rules On April 5, 2024, the Company received a letter (“Letter”) from the Listing Qualifications Staff (the “Staff”) of The Nasdaq Capital Market (“Nasdaq”) notifying the Company that the Company’s shareholders’ equity as reported in its Form 10-K is no longer in compliance with the minimum shareholders’ equity requirement for continued listing on Nasdaq under Nasdaq Listing Rule 5550(b)(1), which requires listed companies to maintain shareholders’ equity of at least $2.5 million (the “Shareholders’ Equity Requirement”). As reported on the Form 10-K, the Company’s shareholders’ deficit as of December 31, 2023 was approximately $0.2 million. As of September 30, 2024, the Company had a shareholders' deficit of $6.7 million and was not in compliance with the Shareholders' Equity Requirement. In accordance with the Nasdaq Listing Rules, on May 20, 2024, the Company submitted a plan to regain compliance with the Stockholders’ Equity Requirement (the “Compliance Plan”) for the Staff’s consideration. On August 5, 2024, the Company was notified by the Staff that it has been granted an extension until September 30, 2024 to comply with the Compliance Plan and evidence compliance with the Shareholders’ Equity Requirement. On October 1, 2024, the Company received a delisting determination letter (“Delisting Determination Letter”) from the Staff notifying the Company that it did not meet the terms of an extension granted by Nasdaq to regain compliance with the Shareholders’ Equity Requirement. On October 8, 2024, the Company requested a hearing (the “Hearing”) before the Nasdaq Listing Qualifications Panel (“Panel”) to appeal the Staff’s delisting determination.   On November 18, 2024, the Company received a letter from the Nasdaq Office of General Counsel notifying the Company that the Company has regained compliance with the Shareholders’ Equity Requirement, and that the Hearing, originally scheduled for November 21, 2024, has been canceled.

Summary of Significant Accounting Policies Basis of presentation – The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information and the rules and regulations of the SEC and assumes that the Company will continue to operate as a going concern. Accordingly, they do not include all the information and footnotes required by U.S. GAAP for complete financial statements. These condensed consolidated financial statements have been prepared on the same basis as the Company’s annual consolidated financial statements and, in the opinion of management, reflect all adjustments, including normal and recurring adjustments, which the Company considers necessary for the fair statement of financial information. The results of operations and comprehensive loss for the three and nine months ended September 30, 2024 are not necessarily indicative of expected results for the fiscal year ended December 31, 2024 or any other future period. These interim condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements as of December 31, 2023 and notes thereto included in its Form 10-K, as filed with the SEC on March 29, 2024. Principles of consolidation – The condensed consolidated financial statements include the accounts of the Company, Celsus Therapeutics, Inc., a Delaware corporation, Volution Immuno Pharmaceuticals SA, a private Swiss company, and Akari Malta Limited, a private Maltese company, each wholly-owned subsidiaries. All intercompany transactions have been eliminated. Foreign currency – The functional currency of the Company is U.S. dollars, as that is the currency of the primary economic environment in which the Company operates as well as the currency in which it has been financed. The reporting currency of the Company is U.S. dollars. The financial statements of certain of the Company's foreign subsidiaries are measured using their local currency as the functional currency. The Company translates its non-U.S. operations’ assets and liabilities denominated in foreign currencies into U.S. dollars at current rates of exchange as of the balance sheet date and income and expense items at the average exchange rate for the reporting period. Translation adjustments resulting from exchange rate fluctuations are recorded as foreign currency translation adjustments, a component of accumulated other comprehensive loss. Gains or losses from foreign currency transactions are included in foreign currency exchange gains/(losses). Use of estimates – The preparation of the Company’s condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that may affect the reported amounts of assets, liabilities, expenses and related disclosures. Significant estimates and assumptions reflected in these condensed consolidated financial statements include, but are not limited to, the valuation of share-based awards, the valuation of warrant liabilities, research and development prepayments, accruals and related expenses, and the valuation allowance for deferred income taxes. The Company bases its estimates on historical experience, known trends and other market-specific or other relevant factors that it believes to be reasonable under the circumstances. Estimates are periodically reviewed considering changes in circumstances, facts and experience. Changes in estimates are recorded in the period in which they become known. Actual results may differ from those estimates or assumptions. Concentration of credit risk – Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash. The Company generally maintains balances in various operating accounts at financial institutions in amounts that may exceed federally insured limits. The Company has not experienced any losses related to its cash and does not believe that it is subject to unusual credit risk beyond the normal credit risk associated with commercial banking relationships. Fair value measurements – Certain assets and liabilities are carried at fair value under U.S. GAAP. Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or a liability. As a basis for considering such assumptions, ASC 820, Fair Value Measurements and Disclosures (“ASC 820”) establishes a three-tier value hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value: • Level 1 – quoted prices in active markets for identical assets and liabilities. • Level 2 – inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. • Level 3 – unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Determining which category an asset or liability falls within the hierarchy requires significant judgment. The Company evaluates its hierarchy disclosures each reporting period. The fair value hierarchy also requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The carrying values of the Company’s cash, prepaid expenses and other current assets, accounts payable and accrued expenses approximate their fair values due to the short-term nature of these assets and liabilities. The Company’s liability-classified warrants are recorded at their estimated fair value. See Note 4. Cash – The Company considers all highly-liquid investments with original maturities of 90 days or less at the time of acquisition to be cash equivalents. The Company had no cash equivalents as of September 30, 2024 or December 31, 2023. Prepaid expenses – Payments made prior to the receipt of goods or services are capitalized until the goods or services are received. Other current assets – Other current assets as of September 30, 2024 and December 31, 2023 were principally comprised of Value Added Tax (“VAT”) receivables. Patent acquisition costs – Patent acquisition costs and related capitalized legal fees are amortized on a straight-line basis over the shorter of the legal or economic life. The estimated useful life is 22 years. The Company expenses costs associated with maintaining and defending patents after their issuance in the period incurred. Amortization expense for each of the three and nine months ended September 30, 2024 and 2023 was less than $0.1 million. Accrued expenses – As part of the process of preparing the condensed consolidated financial statements, the Company estimates accrued expenses. This process involves identifying services that third parties have performed on the Company’s behalf and estimating the level of service performed and the associated cost incurred on these services as of each balance sheet date in the Company’s condensed consolidated financial statements. Examples of estimated accrued expenses include contract service fees in conjunction with pre-clinical and clinical trials, professional service fees and contingent liabilities. In connection with these service fees, the Company’s estimates are most affected by its understanding of the status and timing of services provided relative to the actual services incurred by the service providers. If the Company does not identify certain costs that have been incurred or it under or over-estimates the level of services or costs of such services, the Company’s reported expenses for a reporting period could be understated or overstated. The date on which certain services commence, the level of services performed on or before a given date, and the cost of services are often subject to the Company’s estimation and judgment. The Company makes these judgments based upon the facts and circumstances known to it in accordance with U.S. GAAP. See Note 5. Convertible Notes – On May 10, 2024, the Company entered into unsecured convertible promissory notes (the “May 2024 Notes”) with existing investors: the Company’s Chairman, Dr. Ray Prudo, and Interim President and Chief Executive Officer and director of the Company, Dr. Samir Patel, for an aggregate of $1.0 million in gross proceeds. The May 2024 Notes bear interest at 15% per annum, which may be increased to 17% upon the occurrence of certain events of default as described therein, and the principal and all accrued but unpaid interest is due on the date that is the earlier of (a) ten (10) business days following the Company’s receipt of a U.K. research and development tax credit from HM Revenue and Customs, and (b) November 10, 2024. Provided, however, at any time or times from the date of the note and until the tenth business day prior to closing of the Merger, the note holders are entitled to convert any portion of the outstanding and unpaid amount, including principal and accrued interest, into Company ADSs at a fixed conversion price equal to $1.59, representing the Nasdaq official closing price of the Company’s ADSs on the issuance date, subject to certain restrictions. In October 2024, Drs. Prudo and Patel each elected to convert $125,000 of principal and all accrued interest into Company ADSs, resulting in the issuance of an aggregate of 406,236,000 ordinary shares represented by 203,118 ADSs. The remaining unconverted aggregate principal balance of the May 2024 Notes, or $750,000, was repaid in cash. The Company accounts for convertible promissory notes in accordance with ASC Topic 470-20, Debt with Conversion and Other Options (“ASC 470-20”) and has not elected the fair value option as provided for within ASC Topics 815 and 825. Accordingly, the Company evaluated the embedded conversion and other features within the May 2024 Notes to determine whether any of the embedded features should be bifurcated from the host instrument and accounted for as a derivative at fair value. Based on management’s evaluation, the Company determined that the May 2024 Notes were not issued at a substantial premium and none of the embedded features were required to be bifurcated and accounted for separately. Accordingly, the May 2024 Notes are accounted for as a single liability measured at its amortized cost. Issuance costs incurred in connection with the issuance of the May 2024 Notes were immaterial. Interest expense incurred on the May 2024 Notes was less than $0.1 million for the three and nine months ended September 30, 2024. As of September 30, 2024, accrued interest on the May 2024 Notes of less than $0.1 million is included within “Accrued expenses” in the Company’s balance sheets. Warrant Liability – The Company accounts for ordinary share or ADS warrants as either equity instruments, liabilities or derivative liabilities in accordance with ASC Topic 480, Distinguishing Liabilities from Equity (“ASC 480”) and/or ASC Topic 815, Derivatives and Hedging (“ASC 815”), depending on the specific terms of the warrant agreement. Liability-classified warrants are recorded at their estimated fair values at issuance and are remeasured each reporting period until they are exercised, terminated, reclassified or otherwise settled. Changes in the estimated fair value of liability-classified warrants are recorded in "change in fair value of warrant liability" in the Company’s condensed consolidated statements of operations and comprehensive loss. Equity-classified warrants are recorded within "additional paid-in capital" in the Company's condensed consolidated statements of shareholders' (deficit) equity at the time of issuance and not subject to remeasurement.   In connection with the sale of the ADSs in the September 2022 Registered Direct Offering, the Company issued to the investors registered Series A warrants (“Series A Warrants”) to purchase an aggregate of 755,000 ADSs at $17.00 per ADS and registered Series B warrants (“Series B Warrants”) to purchase an aggregate of 755,000 ADSs at $17.00 per ADS (collectively, the “September 2022 Warrants”).The Company determined that the September 2022 Warrants are not indexed to the Company’s own stock in the manner contemplated by ASC 815-40-15, Determining Whether an Instrument (or Embedded Feature) Is Indexed to an Entity’s Own Stock. Accordingly, the Company classifies the September 2022 Warrants as derivative liabilities in its consolidated balance sheets. In September 2024, all outstanding Series A Warrants expired unexercised. Other Current Liabilities – In February 2024, the Company entered into a short-term financing arrangement with a third-party vendor to finance insurance premiums. The aggregate amount financed under this agreement was $1.1 million, bearing interest at an annual rate of 7.49%. As of September 30, 2024, the balance of $0.2 million, which is included in “Other current liabilities” in the Company’s balance sheets, is scheduled to be paid in monthly installments through November 2024. Research and development expenses – Costs associated with research and development are expensed as incurred unless there is an alternative future use in other research and development projects. Research and development expenses include, among other costs, salaries and personnel–related expenses, fees paid for contract research services, fees paid to clinical research organizations, costs incurred by outside laboratories, manufacturers and other accredited facilities in connection with clinical trials and preclinical studies. Payments made prior to the receipt of goods or services to be used in research and development are capitalized until the goods or services are received. The Company records expenses related to clinical studies and manufacturing development activities based on its estimates of the services received and efforts expended pursuant to contracts with multiple contract research organizations and manufacturing vendors that conduct and manage these activities on its behalf. The financial terms of these agreements are subject to negotiation, vary from contract to contract, and may result in uneven cash flows. There may be instances in which payments made to the Company’s vendors will exceed the level of services provided and result in a prepayment of the expense. Payments under some of these contracts depend on factors such as the successful enrollment of subjects and the completion of clinical study milestones. In amortizing or accruing service fees, the Company estimates the time period over which services will be performed, enrollment of subjects, number of sites activated and the level of effort to be expended in each period. If the actual timing of the performance of services or the level of effort varies from the Company’s estimate, the Company will adjust the accrued or prepaid expense balance accordingly. The Company accounts for research and development tax credits at the time its realization becomes probable as a credit to research and development expenses in the condensed consolidated statements of operations and comprehensive loss. During the three and nine months ended September 30, 2024 and 2023, the Company recognized research and development tax credits of approximately $1.3 million and $2.6 million, respectively. Merger-Related Costs – Merger-related costs include direct expenses incurred in connection with the proposed Merger, as more fully described in Note 3, and are comprised primarily of legal and professional fees and other incremental costs directly associated to the Merger. For the three and nine months ended September 30, 2024 merger-related costs totaled $1.0 million and $2.3 million, respectively.   Restructuring and Other Costs – In May 2024, the Company began to implement a reduction-in-force of approximately 67% of its total workforce as a result of the recently announced program prioritization under which the Company’s HSCT-TMA program was suspended. The reduction-in-force was part of an operational restructuring plan (the “May 2024 Plan”) which included the elimination of certain senior management positions and was completed in the third quarter of 2024. The purpose of the restructuring plan, including the reduction-in-force, was to reduce HSCT-TMA related operating costs, while supporting the execution of the Company’s long-term strategic plan. During the three and nine months ended September 30, 2024, the Company has incurred restructuring-related charges of less than $0.1 million and $1.7 million related to the May 2024 Plan, respectively. Of the $1.7 million incurred during the nine months ended September 30, 2024, $1.4 million related to severance and other settlement payments to terminated executives and employees, and $0.3 million was non-cash expenses related to accelerated vesting of equity awards. The Company does not expect to incur additional restructuring-related expenses related to the May 2024 Plan.   As of September 30, 2024, of the $1.7 million total restructuring-related charges incurred, approximately $0.5 million was unpaid and included in accrued expenses in the accompanying condensed consolidated balance sheet. See Note 5. The Company expects these costs to be paid in the fourth quarter of 2024. Share-based compensation expense – The Company measures all share-based awards granted to employees, directors and non-employees based on the estimated fair value on the date of grant and recognizes compensation expense of those awards over the requisite service period, which is generally the vesting period of the respective awards. Forfeitures are accounted for as they occur. The Company classifies share-based compensation expense in its condensed consolidated statements of operations and comprehensive loss in the same manner in which the award recipient’s payroll costs are classified or in which the award recipient’s service payments are classified. The fair value of each restricted ordinary share award is determined on the date of grant based on the fair value of the Company’s ordinary shares on that same date. The fair value of each share option grant is determined on the date of grant using the Black-Scholes option pricing model, which requires inputs based on certain assumptions, including the expected stock price volatility, the expected term of the award, the risk-free interest rate, and expected dividends. See Note 7. The Company estimates stock price volatility based on the Company’s historical stock price performance over a period of time that matches the expected term of the stock options. The expected term of the Company’s options has been determined utilizing the “simplified” method for awards that qualify as “plain-vanilla” options. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected term of the award. The expected dividend yield is based on the fact that the Company has never paid cash dividends on ordinary shares and does not expect to pay any cash dividends in the foreseeable future. Leases – The Company accounts for its leases in accordance with ASC 842, Leases. In accordance with ASC 842, the Company records a right-of-use (“ROU”) asset and corresponding lease liability on the balance sheet for all leases with terms longer than 12 months. Leases with an initial term of twelve months or less are not recorded on the condensed consolidated balance sheet and are recognized on a straight-line basis over the lease term. As of September 30, 2024 and December 31, 2023, the Company did not have any leases with a term longer than twelve months. Accordingly, no ROU assets and corresponding lease liabilities are included in the Company’s condensed consolidated balance sheets as of September 30, 2024 or December 31, 2023. Income taxes – In accordance with ASC 270, Interim Reporting, and ASC 740, Income Taxes, the Company is required at the end of each interim period to determine the best estimate of its annual effective tax rate and then apply that rate in providing for income taxes on a current year-to-date (interim period) basis. For the three and nine months ended September 30, 2024 and 2023, the Company recorded no tax expense or benefit due to the expected current year loss and its historical losses. The Company has not recorded its net deferred tax asset as of either September 30, 2024 or December 31, 2023 because it maintained a full valuation allowance against all deferred tax assets as of these dates as management has determined that it is not more likely than not that the Company will realize these future tax benefits. As of September 30, 2024 and December 31, 2023, the Company had no uncertain tax positions. Net loss per share – Basic net loss per ordinary share is computed by dividing net loss available to ordinary shareholders by the weighted average number of ordinary shares outstanding during the period, which includes ordinary shares underlying pre-funded warrants, as such warrant is exercisable, in whole or in part, for nominal cash consideration with no expiration date. Diluted net loss per ordinary share includes the effect, if any, from the potential exercise or conversion of securities, such as stock options, unvested restricted stock units, and warrants, which would result in the issuance of incremental ordinary shares, unless their effect would be anti-dilutive. For each of the three and nine months ended September 30, 2024 and 2023, diluted net loss per ordinary share is the same as basic net loss per ordinary share as the effects of the Company’s potentially dilutive securities were anti-dilutive. The following potential dilutive securities, presented based on amounts outstanding at the end of each reporting period, have been excluded from the calculation of diluted net loss per share because including them would have had an anti-dilutive impact:       As of September 30,       2024     2023   Stock options     507,014,688       680,112,400   Restricted stock units     251,823,915       418,580,700   Warrants     11,562,653,300       4,155,347,500   Convertible notes     1,257,860,000       —   Total     13,579,351,903       5,254,040,600     New Accounting Pronouncements – From time to time, new accounting pronouncements are issued by the FASB and rules are issued by the SEC that the Company has or will adopt as of a specified date. Unless otherwise noted, management does not believe that any other recently issued accounting pronouncements issued by the FASB or guidance issued by the SEC had, or is expected to have, a material impact on the Company’s present or future consolidated financial statements.   Recently Issued (Not Yet Adopted) Accounting Pronouncements   In November 2023, the FASB issued Accounting Standards Update (“ASU”) 2023-07, Segment Reporting: Improvements to Reportable Segment Disclosures. This ASU modified the disclosure and presentation requirements primarily through enhanced disclosures of significant segment expenses and clarified that single reportable segment entities must apply Topic 280 in its entirety. This guidance is effective for the Company for the year beginning January 1, 2024, with early adoption permitted. The amendments should be applied retrospectively to all prior periods presented in the financial statement. The Company is currently assessing the impact of this guidance on its consolidated financial statements and related disclosures.   In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures. This ASU improves the transparency of income tax disclosure by requiring consistent categories and greater disaggregation of information in the rate reconciliation, and income taxes paid disaggregated by jurisdiction. This guidance is effective for the Company for the year beginning January 1, 2025, with early adoption permitted. The amendments should be applied on a prospective basis, with retrospective application permitted. The Company is currently assessing the impact of this guidance on its consolidated financial statements and related disclosures.

Agreement And Plan Of Merger [Abstract]
Agreement and Plan of Merger	Note 3. Agreement and Plan of Merger   Agreement and Plan of Merger On March 4, 2024, the Company entered into an Agreement and Plan of Merger with Peak Bio and Pegasus Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of Akari (“Pegasus Merger Sub”), as amended by that certain side letter dated August 15, 2024 (the “Merger Agreement”), pursuant to which, on November 14, 2024, Pegasus Merger Sub merged with and into Peak Bio (the “Merger”), with Peak Bio surviving the Merger as a wholly owned subsidiary of Akari. Pursuant to the Merger Agreement, and upon the terms and subject to the conditions thereof, at the effective time of the Merger (the “Effective Time”), each issued and outstanding share of Peak Bio common stock, par value $0.0001 per share (the “Peak Common Stock”) (other than (x) shares of Peak Common Stock held by Peak Bio as treasury stock, or shares of Peak Common Stock owned by Akari, Pegasus Merger Sub or any direct or indirect wholly owned subsidiaries of Akari and (y) Dissenting Shares (as defined in the Merger Agreement)), was converted into the right to receive the Company’s ADSs representing a number of Akari ordinary shares, par value $0.0001 per share (the “Akari Ordinary Shares”) equal to 0.2935 (the “Exchange Ratio”), each such share duly and validly issued against the deposit of the requisite number of Akari Ordinary Shares in accordance with the Deposit Agreement (as defined in the Merger Agreement). The Exchange Ratio was calculated in accordance with the terms of the Merger Agreement, such that the total number of shares of Akari ADSs issued in connection with the merger was approximately 48.4% of the outstanding shares of Akari ADSs on a fully diluted basis. The board of directors of each of Akari and Peak has unanimously approved the Merger Agreement and the transactions contemplated thereby. On November 14, 2024, the Company closed the business combination contemplated by the Merger Agreement, as more fully described in Note 10.

Fair Value Measurements	Note 4. Fair Value Measurements Assets and Liabilities Measured at Fair Value on a Recurring Basis The following table presents information about the Company’s financial liabilities measured at fair value on a recurring basis and indicates the level of the fair value hierarchy used to determine such values:       September 30, 2024   (In thousands)   Total     Level 1     Level 2     Level 3   Liabilities                         Warrant liability - Series B   $ 725     $ —     $ —     $ 725   Total liabilities   $ 725     $ —     $ —     $ 725         December 31, 2023   (In thousands)   Total     Level 1     Level 2     Level 3   Liabilities                         Warrant liability - Series A   $ 15     $ —     $ —     $ 15   Warrant liability - Series B     1,238       —       —       1,238   Total liabilities   $ 1,253     $ —     $ —     $ 1,253     The Company’s Level 3 liabilities consist of the Series B Warrants as of September 30, 2024 and the Series A and Series B Warrants as of December 31, 2023, which were determined to be liability-classified instruments. There were no transfers between Level 1, Level 2, and Level 3 during the nine months ended September 30, 2024 and 2023. Changes in Level 3 Liabilities Measured at Fair Value on a Recurring Basis The following table summarizes the activity in the warrant liability measured at fair value on a recurring basis using unobservable inputs (Level 3) during the nine months ended September 30, 2024:       Warrant Liability   (In thousands)   Series A     Series B     Total   Balance, December 31, 2023   $ 15     $ 1,238     $ 1,253   Change in the fair value of liability     (15 )     (513 )     (528 ) Balance, September 30, 2024   $ —     $ 725     $ 725     Assumptions Used in Determining Fair Value of Liability-Classified Warrants The fair value of the warrant liability is based on significant inputs, which represents a Level 3 measurement within the fair value hierarchy. The fair value of both the Series A Warrants and the Series B Warrants was determined using the Black-Scholes Option Pricing Model, which uses various assumptions, including (i) fair value of the Company’s ADSs, (ii) exercise price of the warrant, (iii) expected term of the warrant, (iv) expected volatility and (v) expected risk-free interest rate. Below are the assumptions used for the fair value calculations of the Series B Warrants as of September 30, 2024, and Series A Warrants and Series B Warrants as of December 31, 2023:       September 30, 2024     December 31, 2023       Series B     Series A     Series B   Stock (ADS) price   $ 2.95     $ 3.12     $ 3.12   Exercise price   $ 17.00     $ 17.00     $ 17.00   Expected term (in years)     5.0     0.7       5.7   Expected volatility     80.0 %     85.0 %     95.0 % Risk-free interest rate     3.6 %     5.1 %     3.9 % Expected dividend yield     —       —       —

Stockholders' Equity Note [Abstract]
Shareholders' (Deficit) Equity	Note 6. Shareholders’ (Deficit) Equity Ordinary Shares On September 30, 2023, the Company’s shareholders approved an increase to the number of authorized ordinary shares, par value $0.0001 (the “Ordinary Shares”), the Company can issue by 35,000,000,000 ordinary shares in addition to the number of shares outstanding on June 30, 2023. Accordingly, as of September 30, 2024 and December 31, 2023, the Company was authorized to issue up to 45,122,321,523 ordinary shares. Currently, each ADS represents 2,000 Ordinary Shares (the “ADS Ratio”). All ADS and per ADS amounts in the accompanying condensed consolidated financial statements reflect the ADS Ratio. May 2024 Private Placement   In May 2024, the Company entered into a definitive purchase agreement with certain investors, Dr. Prudo and Dr. Patel, pursuant to which the Company sold and issued in a private placement an aggregate of 4,029,754 ADSs, and Series C Warrants (the “Series C Warrants”) to purchase up to 4,029,754 ADS, at a per unit price of $1.885 per ADS and Series C Warrant for aggregate gross proceeds of approximately $7.6 million (the “May 2024 Private Placement”). The Series C Warrants have 3-year terms ranging from May 31, 2027 to June 21, 2027 and have cashless exercise provisions in limited circumstances. The Series C Warrants (other than those issued to Dr. Prudo and Dr. Patel) have an exercise price of $1.76 per ADS. The Series C Warrants issued to Dr. Prudo and Dr. Patel have an exercise price of $1.79 per ADS. Net proceeds from the May 2024 Private Placement were approximately $7.0 million after deducting placement agent fees and other expenses. At close of the May 2024 Private Placement, the Company issued to Paulson Investment Company, LLC (“Paulson”), as placement agent for the May 2024 Private Placement, warrants to purchase 332,380 ADSs at an exercise price of $1.885 per ADS and a term expiring on May 31, 2029 (the “May 2024 Placement Agent Warrants”). The estimated fair value of the May 2024 Placement Agent Warrants on the issuance date was approximately $0.4 million. The Company determined that the Series C Warrants and May 2024 Placement Agent Warrants met all of the criteria for equity classification. Accordingly, upon closing of the May 2024 Private Placement, each of the Series C Warrants and May 2024 Placement Agent Warrants were recorded as a component of additional paid-in capital. March 2024 Private Placement   In March 2024, the Company entered into a definitive purchase agreement with certain existing investors, pursuant to which the Company sold and issued in a private placement an aggregate of 1,320,614 ADSs at $1.48 per ADS, for aggregate gross proceeds of approximately $2.0 million (the “March 2024 Private Placement”). Net proceeds from the March 2024 Private Placement were approximately $1.7 million after deducting placement agent fees and other expenses. At close of the March 2024 Private Placement, the Company issued to Paulson, as placement agent for the March 2024 Private Placement, warrants to purchase 132,061 ADSs at an exercise price of $1.85 per ADS (representing 125% of the purchase price per ADS sold in the March 2024 Private Placement) and a term expiring on March 27, 2029 (the “March 2024 Placement Agent Warrants”). The estimated fair value of the March 2024 Placement Agent Warrants on the issuance date was approximately $0.2 million. The Company determined that the March 2024 Placement Agent Warrants met all of the criteria for equity classification. Accordingly, upon closing of the March 2024 Private Placement, each of the March 2024 Placement Agent Warrants were recorded as a component of additional paid-in capital. December 2023 Private Placement In December 2023, the Company entered into purchase agreements to sell, in a private placement, to existing investors, Dr. Ray Prudo and Dr. Patel, (the “December 2023 Private Placement”) an aggregate of 947,868 ADSs at $2.11 per ADS, for aggregate gross proceeds of approximately $2.0 million. Net proceeds from the December 2023 Private Placement were approximately $1.8 million after deducting placement agent fees and other expenses. September 2023 Private Placement In September 2023, the Company entered into purchase agreements to sell in a private placement to existing investors and directors, including Dr. Prudo and Ms. Rachelle Jacques, the Company’s then President and Chief Executive Officer (the “September 2023 Private Placement”) an aggregate of 551,816 ADSs at $3.30 per ADS, and pre-funded warrants (the “Pre-Funded Warrants”) to purchase up to 48,387 ADSs at a purchase price per Pre-Funded Warrant of $3.10, for aggregate gross proceeds of approximately $2.0 million. The Pre-Funded Warrants are exercisable at an exercise price of $0.20 per ADS and will not expire until exercised in full. The September 2023 Private Placement closed in October 2023 resulting in net proceeds of approximately $1.7 million after deducting placement agent fees and other expenses. At close of the September 2023 Private Placement, the Company issued to Paulson, as placement agent for the September 2023 Private Placement, warrants to purchase 42,550 ADSs at an exercise price of $4.13 per ADS (representing 125% of the purchase price per ADS sold in the September 2023 Private Placement) and a term expiring on October 6, 2028 (the “October 2023 Placement Agent Warrants”). The estimated fair value of the October 2023 Placement Agent Warrants on the issuance date was approximately $0.1 million. The Company determined that the Pre-Funded Warrants and October 2023 Placement Agent Warrants met all of the criteria for equity classification. Accordingly, upon closing of the September 2023 Private Placement, each of the Pre-Funded Warrants and October 2023 Placement Agent Warrants were recorded as a component of additional paid-in capital. March 2023 Registered Direct Offering On March 31, 2023, the Company entered into securities purchase agreements with certain accredited and institutional investors, including Dr. Prudo (the “March Registered Direct Offering”) providing for the issuance of an aggregate of 1,333,333 ADSs in a registered direct offering at $3.00 per ADS, resulting in gross proceeds of approximately $4.0 million. Net proceeds from the March Registered Direct Offering were approximately $3.5 million after deducting placement agent fees and expenses. Warrants In connection with various financing transactions, the Company has issued warrants to purchase the Company’s ordinary shares represented by ADSs. The Company accounts for such warrants as equity instruments or liabilities, depending on the specific terms of the warrant agreement.

The Deferred Shares were created for technical reasons of company law and did not increase the aggregate value of share capital. Also in December 2020, the Deferred Shares were purchased by the Company in accordance with their terms of issue for aggregate consideration of $0.01 and immediately cancelled. The aggregate nominal value at cancellation was $50.6 million.   Amounts transferred from share capital on the redemption of the Deferred Shares of $50.6 million, along with the resulting foreign currency effect of the redenomination of Company ordinary shares of $1.6 million, are classified as "capital redemption reserve" within the Company's condensed consolidated balance sheets and condensed statements of shareholders' (deficit) equity.

Share-Based Payment Arrangement [Abstract]
Stock-Based Compensation	Note 7. Share-Based Compensation 2023 Equity Incentive Plan On June 30, 2023, the Company’s shareholders approved the 2023 Equity Incentive Plan (the “2023 Plan”), which provides for the grant of stock options, both incentive stock options and nonqualified stock options, stock, with and without vesting restrictions, restricted stock units (“RSUs”) and stock appreciation rights, to be granted to employees, directors and consultants. The Company is permitted to issue up to 980,000,000 ordinary shares under the 2023 Plan, plus such additional number of ordinary shares (up to 855,637,300 ordinary shares) subject to awards granted under the 2014 Equity Incentive Plan (the “2014 Plan”), to the extent such awards are forfeited, cancelled, or expire unexercised. As of September 30, 2024, the Company had 498,903,915 ordinary shares underlying outstanding equity awards under the 2023 Plan, consisting of stock options and RSUs, and 569,501,522 ordinary shares remained available for future grants under the 2023 Plan. The 2023 and 2014 Plans provide that they be administered by the compensation committee of the board of directors. The exercise price for stock option awards may not be less than 100% of the fair market value of the Company’s ordinary shares on the date of grant and the term of awards may not be greater than ten years. The Company determines the fair value of its ordinary shares based on the quoted market price of its ADSs. Vesting periods are determined at the discretion of the compensation committee. Awards granted to employees typically vest over two to four years and directors over one year. 2014 Equity Incentive Plan Under the 2014 Plan the Company was authorized to grant stock options, RSUs and other awards, to employees, members of the board of directors and consultants. Upon effectiveness of the 2023 Plan no further awards were available to be issued under the 2014 Plan. As of September 30, 2024, the Company had 259,934,688 ordinary shares underlying outstanding equity awards under the 2014 Plan, consisting of stock options. Stock Options The following is a summary of the Company’s stock option activity under the 2014 Plan and the 2023 Plan for the nine months ended September 30, 2024:   ($ in thousands, except share and per share data)   Stock Options     Weighted- Average Exercise Price     Weighted-Average Remaining Contractual Life (in years)     Aggregate Intrinsic Value   Outstanding at December 31, 2023     651,237,400     $ 0.01       8.5     $ —   Granted     205,080,000       0.00               Exercised     —       —               Forfeited     (304,302,712 )     0.01               Expired     (45,000,000 )     0.02               Outstanding at September 30, 2024 (1)     507,014,688     $ 0.01       6.4     $ 2   Exercisable at September 30, 2024     425,181,355     $ 0.01       6.0     $ —   ___________ (1) Includes both vested stock options as well as unvested stock options for which the requisite service period has not been rendered but that are expected to vest based on achievement of a service condition.   The aggregate intrinsic value of options is calculated as the difference between the exercise price of the options and the fair value of the Company’s ordinary shares for those options that had exercise prices lower than the fair value of the Company’s ordinary shares. The weighted-average grant-date fair value per ordinary share of options granted during each of the nine months ended September 30, 2024 and 2023 was less than $0.01. Option Valuation The weighted-average assumptions that the Company used to determine the fair value of share options granted were as follows, presented on a weighted average basis:       2024     2023   Expected volatility     82.6 %     99.2 % Risk-free interest rate     3.7 %     3.8 % Expected dividend yield     —       —   Expected term (in years)     5.1       6.0     Restricted Stock Units The 2014 Plan provided, and the 2023 Plan provides, for the award of RSUs. RSUs are granted to employees that are subject to time-based vesting conditions that lapse between one year and four years from date of grant, assuming continued employment. Compensation cost for time-based RSUs, which vest only on continued service, is recognized on a straight-line basis over the requisite service period based on the grant date fair of the RSUs, which is derived from the closing price of the Company’s ADSs on the date of grant. The following table summarizes the Company’s RSU activity for the nine months ended September 30, 2024:       Time-based Awards   ($ in thousands, except per share data)   Number of Shares     Weighted-Average Grant Date Fair Value   Nonvested shares at December 31, 2023     385,954,925     $ 0.00   Granted     731,393,807       0.00   Forfeited     (482,249,417 )     0.00   Vested     (383,275,400 )     0.00   Nonvested shares at September 30, 2024     251,823,915     $ 0.00     The fair value of time-based RSUs that vested during the nine months ended September 30, 2024 and 2023 was approximately $0.5 million and $0.2 million, respectively. Share-Based Compensation Expense The Company classifies share-based compensation expense in the statement of operations in the same manner in which the award recipients’ payroll costs are classified or in which the award recipients’ service payments are classified. Total share-based compensation expense attributable to share-based payments made to employees, consultants and directors included in operating expenses in the Company's condensed consolidated statements of operations and comprehensive loss for the three and nine months ended September 30, 2024 and 2023, was as follows:       Three Months Ended     Nine Months Ended       September 30,     September 30,   ($ in thousands)   2024     2023     2024     2023   Research and development   $ 27     $ 42     $ 83     $ 105   General and administrative     221       263       621       741   Restructuring and other costs     -       —       285       —   Total share-based compensation expense   $ 248     $ 305     $ 989     $ 846     During the nine months ended September 30, 2024, 276,000,000 ordinary shares underlying unvested time-based RSUs held by a former executive upon termination of employment were accelerated, resulting in additional stock-based compensation expense of $0.3 million.   As of September 30, 2024, total unrecognized compensation cost related to unvested stock options and time-based RSUs was $0.2 million and $0.2 million, respectively. The Company expects total unrecognized compensation costs related to unvested stock options and RSUs to be recognized over a weighted average period of 1.7 and 1.8 years, respectively.

Prudo and Patel each elected to convert $125,000 of principal and all accrued interest into Company ADSs, resulting in the issuance of an aggregate of 406,236,000 ordinary shares represented by 203,118 ADSs. The remaining unconverted aggregate principal balance of the May 2024 Notes, or $750,000, was repaid in cash.   November Private Placement   On November 13, 2024, the Company entered into a securities purchase agreement with certain investors, including Akari’s Chairman, Dr. Ray Prudo, and a director and Interim President and Chief Executive Officer of the Company, Dr. Samir R. Patel, pursuant to which the Company agreed to sell and issue in a private placement (the “November Private Placement”) an aggregate of 1,713,402 unregistered Akari ADSs, each representing 2,000 of Akari Ordinary Shares, and Series D Warrants (the “Series D Warrants”) to purchase up to 1,713,402 ADSs, at a per unit price of (i) $1.70 per ADS and Series D Warrant for all investors other than Drs. Patel and Prudo, and (ii) $2.385, which is equal to the consolidated closing bid price of the ADSs on The Nasdaq Stock Market on November 12, 2024 plus $0.125 for Drs. Patel and Prudo, for aggregate gross proceeds of $3.2 million. The November Private Placement is expected to close shortly following the closing of the Merger, subject to the satisfaction of customary closing conditions. The Series D Warrants have a term of three years from the closing date of the November Private Placement and have cashless exercise provisions. The Series D Warrants have an exercise price of $2.26 per ADS, which is equal to the Nasdaq official closing price of Akari’s ADSs on the Nasdaq Capital Market on November 12, 2024. The Series D Warrants issued to Dr. Patel and Dr. Prudo are immediately exercisable and the warrants issued to each of the other investors will be exercisable six months after issuance. Akari paid Paulson and Chardan Capital Markets, LLC (“Chardan”) (i) with respect to Paulson, a cash fee equal to 7.0% (or 3.5% for any investor that is a director or affiliate of Akari), and (ii) with respect to Chardan, a cash fee equal to 3.5%, in each case of the aggregate purchase price for the ADSs and Warrants sold in the November Private Placement.   Merger with Peak Bio   On November 14, 2024, the Company completed the previously announced strategic combination contemplated by the Merger Agreement, pursuant to which, Merger Sub merged with and into Peak Bio, with Peak Bio surviving the Merger as a wholly owned subsidiary of Akari. Pursuant to the Merger Agreement, and upon the terms and subject to the conditions thereof, at the Effective Time, each issued and outstanding share of Peak Common Stock (other than (x) shares of Peak Common Stock held by Peak Bio as treasury stock, or shares of Peak Common Stock owned by Akari, Merger Sub or any direct or indirect wholly-owned subsidiaries of Akari and (y) Dissenting Shares (as defined in the Merger Agreement), was converted into the right to receive Akari ADSs representing a number of Akari Ordinary Shares equal to 0.2935 (the “Exchange Ratio”), each such share duly and validly issued against the deposit of the requisite number of Akari Ordinary Shares in accordance with the Deposit Agreement (as defined in the Merger Agreement). The Exchange Ratio was calculated in accordance with the terms of the Merger Agreement and is such that the total number of shares of Akari ADSs issued in connection with the Merger is approximately 48.4% of the outstanding shares of Akari on a fully diluted basis. At the Effective Time, each warrant to purchase capital stock of Peak Bio (“Peak Warrant”) that was outstanding immediately prior to the Effective Time was converted into and exchangeable for warrants to purchase a number of Akari Ordinary Shares or Akari ADSs, as determined by Akari (each, an “Adjusted Warrant”), on substantially similar terms and subject to substantially similar conditions as were applicable to such Peak Warrant immediately prior to the Effective Time, except (i) for terms rendered inoperative by reason of the transactions contemplated by the Merger Agreement, (ii) as provided in the following sentence and (iii) such amendments to the terms of the Adjusted Warrants as are necessary to comply with applicable Law (as defined in the Merger Agreement). The number of Akari Ordinary Shares (or the number of Akari Ordinary Shares underlying Akari ADSs, as applicable) subject to each Adjusted Warrant is equal to the number of shares of Peak Common Stock issuable upon exercise of such Peak Warrant immediately prior to the Effective Time multiplied by the Exchange Ratio, with any fractional Akari Ordinary Shares or Akari ADSs rounded down to the nearest whole Akari Ordinary Share or Akari ADS, as applicable, and the exercise price with respect to each Akari Ordinary Share (or each Akari Ordinary Share underlying Akari ADSs, as applicable) underlying such Adjusted Warrant equal to the exercise price of such Peak Warrant immediately prior to the Effective Time divided by the Exchange Ratio.   At the Effective Time, each option to acquire shares of Peak Common Stock (“Peak Option”) that was outstanding and unexercised immediately prior to the Effective Time, whether or not vested, was assumed and converted into an option to purchase a number of Akari ordinary shares or Akari ADSs, as determined by Akari (each, an “Adjusted Option”). The number of Akari Ordinary Shares (or the number of Akari Ordinary Shares underlying Akari ADSs, as applicable) subject to the Adjusted Option is equal to the product of (i) the total number of shares of Peak Common Stock subject to such Peak Option immediately prior to the Effective Time multiplied by (ii) the Exchange Ratio, with any fractional Akari Ordinary Shares or Akari ADSs rounded down to the nearest whole Akari Ordinary Share or Akari ADS, as applicable, and the exercise price per share of each Adjusted Option equal to the exercise price of such Peak Option immediately prior to the Effective Time divided by the Exchange Ratio.   The issuance of Akari Ordinary Shares, which are represented by Akari ADSs, in connection with the Merger were registered under the Securities Act, pursuant to a registration statement on Form S-4 (File No. 333-282127) filed by Akari with the SEC and declared effective on October 11, 2024.   The parties to the Merger Agreement have agreed that the November Private Placement satisfies the conditions set forth in Sections 7.2(e) and 7.3(e) of the Merger Agreement.   Authorized Shares   On November 7, 2024, the Company’s shareholders approved certain proposals such that the Company’s directors or any duly authorized committee of the directors be generally and unconditionally authorized to (i) allot shares in the Company and to grant rights to subscribe for or to convert any security into shares in the Company up to a maximum aggregate nominal amount of $14,444,680 in connection with the Merger for a period expiring (unless previously renewed, varied or revoked by resolution of Akari) at the conclusion of Akari’s annual general meeting in 2025, and (ii) allot shares in the Company and to grant rights to subscribe for or to convert any security into shares in the Company up to an aggregate nominal amount of $5,546,667 for a period expiring (unless otherwise renewed, varied or revoked by the Company at a general meeting) on November 6, 2029. 2023 Equity Incentive Plan On November 7, 2024, the Company’s shareholders approved an increase in the number of shares available for the grant of awards under the 2023 Plan by 7,800,000,000 Ordinary Shares to an aggregate of 8,780,000,000 Ordinary Shares, plus such additional number of ordinary shares (up to 855,637,300 ordinary shares) subject to awards granted under the 2014 Plan, to the extent such awards are forfeited, cancelled, or expire unexercised.

Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2024
Accounting Policies [Abstract]
Basis of Presentation	Basis of presentation – The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information and the rules and regulations of the SEC and assumes that the Company will continue to operate as a going concern. Accordingly, they do not include all the information and footnotes required by U.S. GAAP for complete financial statements. These condensed consolidated financial statements have been prepared on the same basis as the Company’s annual consolidated financial statements and, in the opinion of management, reflect all adjustments, including normal and recurring adjustments, which the Company considers necessary for the fair statement of financial information. The results of operations and comprehensive loss for the three and nine months ended September 30, 2024 are not necessarily indicative of expected results for the fiscal year ended December 31, 2024 or any other future period. These interim condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements as of December 31, 2023 and notes thereto included in its Form 10-K, as filed with the SEC on March 29, 2024.
Principles of Consolidation	Principles of consolidation – The condensed consolidated financial statements include the accounts of the Company, Celsus Therapeutics, Inc., a Delaware corporation, Volution Immuno Pharmaceuticals SA, a private Swiss company, and Akari Malta Limited, a private Maltese company, each wholly-owned subsidiaries. All intercompany transactions have been eliminated.
Foreign Currency	Foreign currency – The functional currency of the Company is U.S. dollars, as that is the currency of the primary economic environment in which the Company operates as well as the currency in which it has been financed. The reporting currency of the Company is U.S. dollars. The financial statements of certain of the Company's foreign subsidiaries are measured using their local currency as the functional currency. The Company translates its non-U.S. operations’ assets and liabilities denominated in foreign currencies into U.S. dollars at current rates of exchange as of the balance sheet date and income and expense items at the average exchange rate for the reporting period. Translation adjustments resulting from exchange rate fluctuations are recorded as foreign currency translation adjustments, a component of accumulated other comprehensive loss. Gains or losses from foreign currency transactions are included in foreign currency exchange gains/(losses).
Use of Estimates	Use of estimates – The preparation of the Company’s condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that may affect the reported amounts of assets, liabilities, expenses and related disclosures. Significant estimates and assumptions reflected in these condensed consolidated financial statements include, but are not limited to, the valuation of share-based awards, the valuation of warrant liabilities, research and development prepayments, accruals and related expenses, and the valuation allowance for deferred income taxes. The Company bases its estimates on historical experience, known trends and other market-specific or other relevant factors that it believes to be reasonable under the circumstances. Estimates are periodically reviewed considering changes in circumstances, facts and experience. Changes in estimates are recorded in the period in which they become known. Actual results may differ from those estimates or assumptions.
Concentration of Credit Risk	Concentration of credit risk – Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash. The Company generally maintains balances in various operating accounts at financial institutions in amounts that may exceed federally insured limits. The Company has not experienced any losses related to its cash and does not believe that it is subject to unusual credit risk beyond the normal credit risk associated with commercial banking relationships.
Fair Value Measurements	Fair value measurements – Certain assets and liabilities are carried at fair value under U.S. GAAP. Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or a liability. As a basis for considering such assumptions, ASC 820, Fair Value Measurements and Disclosures (“ASC 820”) establishes a three-tier value hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value: • Level 1 – quoted prices in active markets for identical assets and liabilities. • Level 2 – inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. • Level 3 – unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Determining which category an asset or liability falls within the hierarchy requires significant judgment. The Company evaluates its hierarchy disclosures each reporting period. The fair value hierarchy also requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The carrying values of the Company’s cash, prepaid expenses and other current assets, accounts payable and accrued expenses approximate their fair values due to the short-term nature of these assets and liabilities. The Company’s liability-classified warrants are recorded at their estimated fair value.
Cash	Cash – The Company considers all highly-liquid investments with original maturities of 90 days or less at the time of acquisition to be cash equivalents. The Company had no cash equivalents as of September 30, 2024 or December 31, 2023.
Prepaid Expenses	Prepaid expenses – Payments made prior to the receipt of goods or services are capitalized until the goods or services are received.
Other Current Assets	Other current assets – Other current assets as of September 30, 2024 and December 31, 2023 were principally comprised of Value Added Tax (“VAT”) receivables.
Patent Acquisition Costs	Patent acquisition costs – Patent acquisition costs and related capitalized legal fees are amortized on a straight-line basis over the shorter of the legal or economic life. The estimated useful life is 22 years. The Company expenses costs associated with maintaining and defending patents after their issuance in the period incurred. Amortization expense for each of the three and nine months ended September 30, 2024 and 2023 was less than $0.1 million.
Accrued Expenses	Accrued expenses – As part of the process of preparing the condensed consolidated financial statements, the Company estimates accrued expenses. This process involves identifying services that third parties have performed on the Company’s behalf and estimating the level of service performed and the associated cost incurred on these services as of each balance sheet date in the Company’s condensed consolidated financial statements. Examples of estimated accrued expenses include contract service fees in conjunction with pre-clinical and clinical trials, professional service fees and contingent liabilities. In connection with these service fees, the Company’s estimates are most affected by its understanding of the status and timing of services provided relative to the actual services incurred by the service providers. If the Company does not identify certain costs that have been incurred or it under or over-estimates the level of services or costs of such services, the Company’s reported expenses for a reporting period could be understated or overstated. The date on which certain services commence, the level of services performed on or before a given date, and the cost of services are often subject to the Company’s estimation and judgment. The Company makes these judgments based upon the facts and circumstances known to it in accordance with U.S. GAAP. See Note 5.
Convertible Notes	Convertible Notes – On May 10, 2024, the Company entered into unsecured convertible promissory notes (the “May 2024 Notes”) with existing investors: the Company’s Chairman, Dr. Ray Prudo, and Interim President and Chief Executive Officer and director of the Company, Dr. Samir Patel, for an aggregate of $1.0 million in gross proceeds. The May 2024 Notes bear interest at 15% per annum, which may be increased to 17% upon the occurrence of certain events of default as described therein, and the principal and all accrued but unpaid interest is due on the date that is the earlier of (a) ten (10) business days following the Company’s receipt of a U.K. research and development tax credit from HM Revenue and Customs, and (b) November 10, 2024. Provided, however, at any time or times from the date of the note and until the tenth business day prior to closing of the Merger, the note holders are entitled to convert any portion of the outstanding and unpaid amount, including principal and accrued interest, into Company ADSs at a fixed conversion price equal to $1.59, representing the Nasdaq official closing price of the Company’s ADSs on the issuance date, subject to certain restrictions. In October 2024, Drs. Prudo and Patel each elected to convert $125,000 of principal and all accrued interest into Company ADSs, resulting in the issuance of an aggregate of 406,236,000 ordinary shares represented by 203,118 ADSs. The remaining unconverted aggregate principal balance of the May 2024 Notes, or $750,000, was repaid in cash. The Company accounts for convertible promissory notes in accordance with ASC Topic 470-20, Debt with Conversion and Other Options (“ASC 470-20”) and has not elected the fair value option as provided for within ASC Topics 815 and 825. Accordingly, the Company evaluated the embedded conversion and other features within the May 2024 Notes to determine whether any of the embedded features should be bifurcated from the host instrument and accounted for as a derivative at fair value. Based on management’s evaluation, the Company determined that the May 2024 Notes were not issued at a substantial premium and none of the embedded features were required to be bifurcated and accounted for separately. Accordingly, the May 2024 Notes are accounted for as a single liability measured at its amortized cost. Issuance costs incurred in connection with the issuance of the May 2024 Notes were immaterial. Interest expense incurred on the May 2024 Notes was less than $0.1 million for the three and nine months ended September 30, 2024. As of September 30, 2024, accrued interest on the May 2024 Notes of less than $0.1 million is included within “Accrued expenses” in the Company’s balance sheets.
Warrant Liability	Warrant Liability – The Company accounts for ordinary share or ADS warrants as either equity instruments, liabilities or derivative liabilities in accordance with ASC Topic 480, Distinguishing Liabilities from Equity (“ASC 480”) and/or ASC Topic 815, Derivatives and Hedging (“ASC 815”), depending on the specific terms of the warrant agreement. Liability-classified warrants are recorded at their estimated fair values at issuance and are remeasured each reporting period until they are exercised, terminated, reclassified or otherwise settled. Changes in the estimated fair value of liability-classified warrants are recorded in "change in fair value of warrant liability" in the Company’s condensed consolidated statements of operations and comprehensive loss. Equity-classified warrants are recorded within "additional paid-in capital" in the Company's condensed consolidated statements of shareholders' (deficit) equity at the time of issuance and not subject to remeasurement.   In connection with the sale of the ADSs in the September 2022 Registered Direct Offering, the Company issued to the investors registered Series A warrants (“Series A Warrants”) to purchase an aggregate of 755,000 ADSs at $17.00 per ADS and registered Series B warrants (“Series B Warrants”) to purchase an aggregate of 755,000 ADSs at $17.00 per ADS (collectively, the “September 2022 Warrants”).The Company determined that the September 2022 Warrants are not indexed to the Company’s own stock in the manner contemplated by ASC 815-40-15, Determining Whether an Instrument (or Embedded Feature) Is Indexed to an Entity’s Own Stock. Accordingly, the Company classifies the September 2022 Warrants as derivative liabilities in its consolidated balance sheets. In September 2024, all outstanding Series A Warrants expired unexercised.
Other Current Liabilities	Other Current Liabilities – In February 2024, the Company entered into a short-term financing arrangement with a third-party vendor to finance insurance premiums. The aggregate amount financed under this agreement was $1.1 million, bearing interest at an annual rate of 7.49%. As of September 30, 2024, the balance of $0.2 million, which is included in “Other current liabilities” in the Company’s balance sheets, is scheduled to be paid in monthly installments through November 2024.
Research and Development Expenses	Research and development expenses – Costs associated with research and development are expensed as incurred unless there is an alternative future use in other research and development projects. Research and development expenses include, among other costs, salaries and personnel–related expenses, fees paid for contract research services, fees paid to clinical research organizations, costs incurred by outside laboratories, manufacturers and other accredited facilities in connection with clinical trials and preclinical studies. Payments made prior to the receipt of goods or services to be used in research and development are capitalized until the goods or services are received. The Company records expenses related to clinical studies and manufacturing development activities based on its estimates of the services received and efforts expended pursuant to contracts with multiple contract research organizations and manufacturing vendors that conduct and manage these activities on its behalf. The financial terms of these agreements are subject to negotiation, vary from contract to contract, and may result in uneven cash flows. There may be instances in which payments made to the Company’s vendors will exceed the level of services provided and result in a prepayment of the expense. Payments under some of these contracts depend on factors such as the successful enrollment of subjects and the completion of clinical study milestones. In amortizing or accruing service fees, the Company estimates the time period over which services will be performed, enrollment of subjects, number of sites activated and the level of effort to be expended in each period. If the actual timing of the performance of services or the level of effort varies from the Company’s estimate, the Company will adjust the accrued or prepaid expense balance accordingly. The Company accounts for research and development tax credits at the time its realization becomes probable as a credit to research and development expenses in the condensed consolidated statements of operations and comprehensive loss. During the three and nine months ended September 30, 2024 and 2023, the Company recognized research and development tax credits of approximately $1.3 million and $2.6 million, respectively.
Merger-Related Costs	Merger-Related Costs – Merger-related costs include direct expenses incurred in connection with the proposed Merger, as more fully described in Note 3, and are comprised primarily of legal and professional fees and other incremental costs directly associated to the Merger. For the three and nine months ended September 30, 2024 merger-related costs totaled $1.0 million and $2.3 million, respectively.
Restructuring and Other Costs	Restructuring and Other Costs – In May 2024, the Company began to implement a reduction-in-force of approximately 67% of its total workforce as a result of the recently announced program prioritization under which the Company’s HSCT-TMA program was suspended. The reduction-in-force was part of an operational restructuring plan (the “May 2024 Plan”) which included the elimination of certain senior management positions and was completed in the third quarter of 2024. The purpose of the restructuring plan, including the reduction-in-force, was to reduce HSCT-TMA related operating costs, while supporting the execution of the Company’s long-term strategic plan. During the three and nine months ended September 30, 2024, the Company has incurred restructuring-related charges of less than $0.1 million and $1.7 million related to the May 2024 Plan, respectively. Of the $1.7 million incurred during the nine months ended September 30, 2024, $1.4 million related to severance and other settlement payments to terminated executives and employees, and $0.3 million was non-cash expenses related to accelerated vesting of equity awards. The Company does not expect to incur additional restructuring-related expenses related to the May 2024 Plan.   As of September 30, 2024, of the $1.7 million total restructuring-related charges incurred, approximately $0.5 million was unpaid and included in accrued expenses in the accompanying condensed consolidated balance sheet. See Note 5. The Company expects these costs to be paid in the fourth quarter of 2024.
Share-Based Compensation	Share-based compensation expense – The Company measures all share-based awards granted to employees, directors and non-employees based on the estimated fair value on the date of grant and recognizes compensation expense of those awards over the requisite service period, which is generally the vesting period of the respective awards. Forfeitures are accounted for as they occur. The Company classifies share-based compensation expense in its condensed consolidated statements of operations and comprehensive loss in the same manner in which the award recipient’s payroll costs are classified or in which the award recipient’s service payments are classified. The fair value of each restricted ordinary share award is determined on the date of grant based on the fair value of the Company’s ordinary shares on that same date. The fair value of each share option grant is determined on the date of grant using the Black-Scholes option pricing model, which requires inputs based on certain assumptions, including the expected stock price volatility, the expected term of the award, the risk-free interest rate, and expected dividends. See Note 7. The Company estimates stock price volatility based on the Company’s historical stock price performance over a period of time that matches the expected term of the stock options. The expected term of the Company’s options has been determined utilizing the “simplified” method for awards that qualify as “plain-vanilla” options. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected term of the award. The expected dividend yield is based on the fact that the Company has never paid cash dividends on ordinary shares and does not expect to pay any cash dividends in the foreseeable future.
Leases	Leases – The Company accounts for its leases in accordance with ASC 842, Leases. In accordance with ASC 842, the Company records a right-of-use (“ROU”) asset and corresponding lease liability on the balance sheet for all leases with terms longer than 12 months. Leases with an initial term of twelve months or less are not recorded on the condensed consolidated balance sheet and are recognized on a straight-line basis over the lease term. As of September 30, 2024 and December 31, 2023, the Company did not have any leases with a term longer than twelve months. Accordingly, no ROU assets and corresponding lease liabilities are included in the Company’s condensed consolidated balance sheets as of September 30, 2024 or December 31, 2023.
Income Taxes	Income taxes – In accordance with ASC 270, Interim Reporting, and ASC 740, Income Taxes, the Company is required at the end of each interim period to determine the best estimate of its annual effective tax rate and then apply that rate in providing for income taxes on a current year-to-date (interim period) basis. For the three and nine months ended September 30, 2024 and 2023, the Company recorded no tax expense or benefit due to the expected current year loss and its historical losses. The Company has not recorded its net deferred tax asset as of either September 30, 2024 or December 31, 2023 because it maintained a full valuation allowance against all deferred tax assets as of these dates as management has determined that it is not more likely than not that the Company will realize these future tax benefits. As of September 30, 2024 and December 31, 2023, the Company had no uncertain tax positions.
Net loss per share	Net loss per share – Basic net loss per ordinary share is computed by dividing net loss available to ordinary shareholders by the weighted average number of ordinary shares outstanding during the period, which includes ordinary shares underlying pre-funded warrants, as such warrant is exercisable, in whole or in part, for nominal cash consideration with no expiration date. Diluted net loss per ordinary share includes the effect, if any, from the potential exercise or conversion of securities, such as stock options, unvested restricted stock units, and warrants, which would result in the issuance of incremental ordinary shares, unless their effect would be anti-dilutive. For each of the three and nine months ended September 30, 2024 and 2023, diluted net loss per ordinary share is the same as basic net loss per ordinary share as the effects of the Company’s potentially dilutive securities were anti-dilutive. The following potential dilutive securities, presented based on amounts outstanding at the end of each reporting period, have been excluded from the calculation of diluted net loss per share because including them would have had an anti-dilutive impact:       As of September 30,       2024     2023   Stock options     507,014,688       680,112,400   Restricted stock units     251,823,915       418,580,700   Warrants     11,562,653,300       4,155,347,500   Convertible notes     1,257,860,000       —   Total     13,579,351,903       5,254,040,600
New Accounting Pronouncements	New Accounting Pronouncements – From time to time, new accounting pronouncements are issued by the FASB and rules are issued by the SEC that the Company has or will adopt as of a specified date. Unless otherwise noted, management does not believe that any other recently issued accounting pronouncements issued by the FASB or guidance issued by the SEC had, or is expected to have, a material impact on the Company’s present or future consolidated financial statements.   Recently Issued (Not Yet Adopted) Accounting Pronouncements   In November 2023, the FASB issued Accounting Standards Update (“ASU”) 2023-07, Segment Reporting: Improvements to Reportable Segment Disclosures. This ASU modified the disclosure and presentation requirements primarily through enhanced disclosures of significant segment expenses and clarified that single reportable segment entities must apply Topic 280 in its entirety. This guidance is effective for the Company for the year beginning January 1, 2024, with early adoption permitted. The amendments should be applied retrospectively to all prior periods presented in the financial statement. The Company is currently assessing the impact of this guidance on its consolidated financial statements and related disclosures.   In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures. This ASU improves the transparency of income tax disclosure by requiring consistent categories and greater disaggregation of information in the rate reconciliation, and income taxes paid disaggregated by jurisdiction. This guidance is effective for the Company for the year beginning January 1, 2025, with early adoption permitted. The amendments should be applied on a prospective basis, with retrospective application permitted. The Company is currently assessing the impact of this guidance on its consolidated financial statements and related disclosures.
