CAUTIONARY STATEMENT

In February 2024, Kineta, Inc. (the “Company”) initiated a process to explore a range of strategic alternatives to maximize shareholder value. Potential strategic alternatives that may be evaluated include sale of assets of the Company, a sale of the Company, licensing of assets, a merger, liquidation or other strategic action. There is no set timetable for this process and there can be no assurance that this process will result in the Company pursuing a transaction or that any transaction, if pursued, will be completed on attractive terms. Additionally, there can be no assurances that any particular course of action, business arrangement or transaction, or series of transactions, will be pursued, successfully consummated, or lead to increased stockholder value. If the strategic process is unsuccessful, the Company’s Board of Directors (the “Board”) may decide to pursue a liquidation or obtain relief under the US Bankruptcy Code.

Kineta, Inc. cautions that trading in the Company’s securities is highly speculative and poses substantial risks. Trading prices for the Company’s securities may bear little or no relationship to the actual value realized, if any, by holders of the Company’s securities. Accordingly, the Company urges extreme caution with respect to existing and future investments in its securities.

 

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

 

This Quarterly Report on Form 10-Q contains certain statements that constitute “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the “safe harbor” provisions of the United States Private Securities Litigation Reform Act of 1995. In some cases, you can identify these forward-looking statements by the use of terms such as “expect,” “will,” “continue,” “believe,” “estimate,” “aim,” “project,” “intend,” “should,” “is to be,” or similar expressions, and variations or negatives of these words, but the absence of these words does not mean that a statement is not forward-looking. All statements other than statements of historical fact are statements that could be deemed forward-looking statements. These forward-looking statements are subject to known and unknown risks, uncertainties and other factors that may cause our actual results, levels of activity, performance, or achievements to differ materially from results expressed or implied in this Quarterly Report on Form 10-Q. The following factors, among others, could cause actual results to differ materially from those described in these forward-looking statements:

The forward-looking statements contained in this Quarterly Report on Form 10-Q and the documents incorporated herein by reference are based on our current expectations and beliefs concerning future developments and their potential effects on our business. There can be no assurance that future developments affecting our business will be those that we have anticipated. These forward-looking statements involve a number of risks, uncertainties (some of which are beyond our control) or other assumptions that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking statements. These risks and uncertainties include, but are not limited to, those factors described under the caption “Risk Factors” in Part II, Item 1A of this Quarterly Report on Form 10-Q and under similar headings in the documents that are incorporated by reference herein.

 

Moreover, we operate in a very competitive and rapidly changing environment. New risks and uncertainties emerge from time to time and it is not possible for us to predict all such risk factors, nor can we assess the effect of all such risk factors on our business or the extent to which any factor or combination of factors may cause actual results to differ materially from those contained in any forward-looking statements. Should one or more of these risks or uncertainties materialize, or should any of the assumptions prove incorrect, actual results may vary in material respects from those projected in these forward-looking statements.

The forward-looking statements made by us in this Quarterly Report on Form 10-Q and the documents incorporated herein by reference speak only as of the date of such statement. Except to the extent required under the federal securities laws and rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”), we disclaim any obligation to update any forward-looking statement to reflect events or circumstances after the date on which the statement is made or to reflect the occurrence of unanticipated events. In light of these risks and uncertainties, there is no assurance that the events or results suggested by the forward-looking statements will in fact occur, and you should not place undue reliance on these forward-looking statements.

 

Although we undertake no obligation to revise or update any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law, you are advised to consult any additional disclosures we make in the documents that we file with the SEC.

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 our unaudited condensed consolidated financial statements and related notes appearing elsewhere in this Quarterly Report on Form 10-Q. Some of the information contained in this discussion and analysis or set forth elsewhere in this Quarterly Report on Form 10-Q, including information with respect to our plans and strategy for our business, includes forward-looking statements that involve risks and uncertainties. As a result of many factors, including those factors set forth in the “Risk Factors” section of this Quarterly Report on Form 10-Q, our actual results could differ materially from the results described in, or implied by, the forward-looking statements contained in the following discussion and analysis.

Overview

On February 29, 2024, we announced that we had completed a review of our business, including the status of our programs, resources and

capabilities. Following this review, we implemented a significant corporate restructuring to substantially reduce expenses and preserve cash. The restructuring included a reduction in our workforce by approximately 64% and the termination of enrollment of new patients in our ongoing VISTA-101 Phase 1/2 clinical trial evaluating KVA12123 in patients with advanced solid tumors. Patients currently enrolled in the trial will be permitted to continue to participate. We have made this decision, in part, because certain investors have indicated they will not be able to fulfill their contractual obligation to consummate the Private Placement (as defined below).

 

Due to the fact that we are unable to consummate the Private Placement, management and the Board has determined that it was in the best interests of the stockholders to seek a strategic alternative so that we could continue to operate. If the strategic process is unsuccessful, the Board may decide to pursue a liquidation or obtain relief under the US Bankruptcy Code.

 

On July 3, 2024, we announced that we entered into an exclusivity and right of first offer agreement (the “TuHURA Agreement”) by and between us and TuHURA Biosciences, Inc., a Delaware corporation (“TuHURA”).

 

Pursuant to the TuHURA Agreement, among other things, we have granted TuHURA an exclusive right to acquire our worldwide patents, patent rights, patent applications, product and development program assets, technical and business information, and other rights and assets associated with and derived from our development program related to KVA12123, our VISTA blocking immunotherapy, during the period commencing as of the Effective Date and continuing through the first to occur of (a) the execution of any Definitive Agreement (as defined in the TuHURA Agreement) with respect to a Potential Transaction (as defined in the TuHURA Agreement) by TuHURA or one or more of its affiliates and (b) 11:59 PM Eastern Time on October 1, 2024, subject to extension as noted in the following sentence (the “Exclusivity Period”). In the event that the Parties are engaged in good faith discussions regarding a Potential Transaction on the date on which the Exclusivity Period (or any renewal thereof) is scheduled to expire and TuHURA has not yet closed the transactions contemplated by that previously announced agreement and plan of merger by and among TuHURA, Kintara Therapeutics, Inc. (“Kintara”) and Kayak Mergeco, Inc., a wholly-owned subsidiary of Kintara, then on such date, the Exclusivity Period shall automatically renew for an additional ten (10) day period (a “Renewal Period”) (up to a total of two (2) renewal periods for an aggregate of twenty (20) days).

 

In consideration for our compliance with our obligations set forth in the TuHURA Agreement, TuHURA paid to us $5.0 million (the “Exclusivity Payment”), of which $2.5 million was paid on July 3, 2024 and the remaining $2.5 million was paid on July 15, 2024. No later than two (2) business days after a Renewal Period has started (to be confirmed in writing by both Parties), TuHURA shall pay an additional $150,000 as an additional Exclusivity Payment, in an amount not to exceed $300,000 for the two (2) available Renewal Periods. The Exclusivity Payment will be credited against the initial cash consideration that may be payable to Kineta pursuant to any Definitive Agreement (if any) between Kineta and TuHURA and/or its affiliates with respect to a Potential Transaction.

 

The Company cautions that trading in the Company’s securities is highly speculative and poses substantial risks. Trading prices for the Company’s securities may bear little or no relationship to the actual value realized, if any, by holders of the Company’s securities. In the event of liquidation, bankruptcy or other wind-down event, holders of our securities will likely suffer a total loss of their investment. Accordingly, the Company urges extreme caution with respect to existing and future investments in its securities.

 

We are a clinical-stage biotechnology company with a mission to develop next-generation immunotherapies that transform patients’ lives. We have leveraged our expertise in innate immunity and are focused on discovering and developing potentially differentiated immunotherapies that address the mechanisms of cancer immune resistance:

Our pipeline of assets and research interests includes (i) KVA12123, a monoclonal antibody (“mAb”) immunotherapy targeting VISTA (V-domain Ig suppressor of T cell activation) and (ii) an anti-CD27 agonist mAb immunotherapy. These immunotherapies have the potential to address disease areas with unmet medical needs and significant commercial potential.

KVA12123 is a VISTA blocking immunotherapy in development as an intravenous infusion dosed every two weeks. We dosed the first patient in a Phase 1/2 clinical trial of KVA12123 in the United States in April 2023. The ongoing Phase 1/2 clinical study is designed to evaluate KVA12123 as a monotherapy and in combination with the immune checkpoint inhibitor pembrolizumab in patients with advanced solid tumors. Initial monotherapy

---

safety, pharmacokinetic and biomarker data were presented at the Society for Immunotherapy of Cancer’s (SITC) annual meeting in November 2023. KVA12123 was designed to be a differentiated VISTA blocking immunotherapy to address the problem of immunosuppression in the TME. It is a fully human engineered IgG1 monoclonal antibody that binds to VISTA through a unique epitope and across neutral and acidic pHs. KVA12123 may be an effective immunotherapy for many types of cancer, including non-small cell lung cancer (“NSCLC”), colorectal cancer (“CRC”), ovarian cancer (“OC”), renal cell carcinoma (“RCC”) and head and neck squamous cell carcinoma (“HNSCC”). These indications represent a significant unmet medical need with a large worldwide commercial opportunity for KVA12123.

 

We are also developing an anti-CD27 agonist mAb immunotherapy to address the problem of exhausted T cells. The nominated lead candidate is a fully human mAb that demonstrates nanomolar (“nM”) binding affinity to CD27 in humans. In preclinical studies, our lead anti-CD27 candidate demonstrated antitumor efficacy as a single agent and in combination with other immunotherapies in multiple solid and hematological preclinical tumor models. CD27 is a clinically validated target that may be an effective immunotherapy for advanced solid tumors including RCC, CRC and OC. We continue to conduct preclinical studies to optimize its lead anti-CD27 agonist mAb clinical candidate and to evaluate it in combination with other checkpoint inhibitors.

 

According to Market Data Forecast, the immuno-oncology market generated sales of approximately $111 billion in 2023 and is forecast to reach $201 billion in 2028. If we successfully complete the clinical trial program for KVA12123 and if we subsequently obtain regulatory approval for KVA12123, we will focus on initial target indications in NSCLC, CRC and OC. Initially, the clinical development of KVA12123 will be as a second-line therapy in these indications. These three cancer therapy segments represent a forecasted $48 billion market opportunity in 2027 according to GlobalData.

 

We are a leader in the field of innate immunity and are focused on developing potentially differentiated immunotherapies. With KVA12123 in clinical development and the lead anti-CD27 agonist mAb in preclinical development, we believe we are positioned to achieve multiple value-driving catalysts. We have assembled an experienced management team, a seasoned research and clinical team, an immuno-oncology focused scientific advisory board, and a leading intellectual property position to advance our pipeline of potential novel immunotherapies for cancer patients.

Since our inception in 2007, we have devoted substantially all of our resources to raising capital, licensing certain technology and intellectual property rights, identifying and developing potential product candidates, conducting research and development activities, including preclinical studies and clinical trials, organizing and staffing operations and providing general and administrative support for these operations.

We have no products approved for commercial sale and have not generated any revenue from product sales. To date, revenue has been generated from the out-licensing of certain rights to third parties, providing research services under licensing and collaboration agreements as well as revenue from government grants.

We have never been profitable and have incurred operating losses in each period since inception. Our net losses were $12.9 million for the six months ended June 30, 2024 and $6.1 million for the six months ended June 30, 2023. As of June 30, 2024, we had an accumulated deficit of $178.6 million.

We expect to incur significant expenses and continued operating losses for at least the next several years as we initiate and continue the clinical development of, and seek regulatory approval for, our product candidates and add personnel necessary to advance our pipeline of clinical-stage product candidates. In addition, operating as a publicly-traded company will involve the hiring of additional financial and other personnel, and the incurrence of substantial other costs associated with operating as a public company. We expect that our operating losses will fluctuate significantly from quarter to quarter and year to year due to timing of clinical development programs and efforts to achieve regulatory approval.

From inception to June 30, 2024, we have raised cash from sales and issuances of common stock and borrowings under notes payable. As of June 30, 2024, we had cash of $900,000, and there is substantial doubt about our ability to continue as a going concern. For more information, see the risk factor in Item 1A. of this Quarterly Report on Form 10-Q entitled, “Kineta identified conditions and events that raise substantial doubt about its ability to continue as a going concern, Kineta needs substantial additional funding, and if Kineta is unable to raise capital when needed or on favorable terms, its business, financial condition, and results of operation could be materially and adversely affected.”

In connection and concurrently with the execution of the Merger Agreement (as defined above), we entered into a financing agreement, dated as of June 5, 2022, as amended on October 24, 2022, December 5, 2022, March 29, 2023, May 1, 2023, July 21, 2023 and October 13, 2023 (such financing agreement, as amended, the “Securities Purchase Agreement”) with certain investors to sell shares of our common stock to such investors in a private placement (the “Private Placement”). We and the investors entered into an amendment to the Securities Purchase Agreement on October 13, 2023 to, among other things, extend the date of the second closing from October 31, 2023 to April 15, 2024.

The first closing of the Private Placement occurred on December 16, 2022 and we issued 649,346 shares of our common stock and received net proceeds of $7.4 million. The second closing of the Private Placement for an aggregate purchase price of $22.5 million was expected to occur on April 15, 2024, however, the investors failed to fulfill their contractual obligation to fund and the second closing did not occur. We have reached a settlement with one investor and have initiated litigation against the other investors which failed to fund their obligations.

Geopolitical Developments

---

Geopolitical developments, such as the Russian invasion of Ukraine, the conflict in Israel and the Gaza Strip or deterioration in the bilateral relationship between the United States and China, may impact government spending, international trade and market stability, and cause weaker macro-economic conditions. The impact of these developments, including any resulting sanctions, export controls or other restrictive actions that may be imposed against governmental or other entities in, for example, Russia, have in the past contributed and may in the future contribute to disruption, instability and volatility in the global markets, which in turn could adversely impact our operations and weaken our financial results. Certain political developments may also lead to uncertainty to regulations and rules that may materially affect our business.

 

 

Nasdaq Bid Price Deficiency Letter

On April 18, 2024, the Company received written notice (the “Notice”) from the Listing Qualifications Department of The Nasdaq Stock Market LLC (“Nasdaq”) stating that the Company is not in compliance with Nasdaq Listing Rule 5550(a)(2) (the “Rule”) because the Company has not maintained a minimum closing bid price of the Company’s common stock of at least $1.00 per share for the last 30 consecutive business days. The Notice has no immediate effect on the listing or trading of the Company’s securities.

 

The Company has 180 calendar days from the date of the Notice, or until October 15, 2024, to regain compliance. If the Company is not deemed in compliance before the expiration of the 180 day compliance period, it will be afforded an additional 180-day compliance period, provided that on the 180th day of the first compliance period it meets the applicable market value of publicly held shares requirement for continued listing and all other applicable standards for initial listing on The Nasdaq Capital Market (except the bid price requirement) based on the Company's most recent public filings and market information and provides written notice to Nasdaq of its intention to cure this deficiency during the second compliance period.

 

Compliance can be achieved during any compliance period by meeting the applicable standard for a minimum of 10 consecutive business days during the applicable compliance period, unless Nasdaq exercises its discretion to extend this 10 day period as discussed in Rule 5810(c)(3)(H).

 

If the Company does not regain compliance with the bid price requirement within the compliance period, the Company’s common stock will be subject to delisting. In the event the Company receives notice that the Company’s common stock is being delisted, Nasdaq’s rules permit the Company to appeal the delisting determination by the Nasdaq staff (the “Staff”) to a hearings panel.

 

The Company intends to monitor the bid price of the Company’s listed securities and may, if appropriate, consider available options to regain compliance with the bid price requirement.

 

There can be no assurance that the Company will be able to regain compliance with the bid price requirement.

 

Nasdaq Stockholders' Equity Deficiency Letter

 

On May 23, 2024, the Company received written notice (the “Equity Notice”) from Nasdaq informing the Company that it no longer complies with the requirement under Nasdaq Listing Rule 5550(b)(1) to maintain a minimum of $2,500,000 in stockholders’ equity for continued listing on Nasdaq because the Company reported stockholders’ equity of negative $6,243,000 in its Quarterly Report on Form 10-Q for the period ended March 31, 2024, and, as of the date of the Equity Notice, the Company did not meet the alternatives of market value of listed securities or net income from continuing operations. The Notice has no immediate effect on the listing or trading of the Company’s securities.

 

The Company timely submitted the compliance plan to the Staff on July 8, 2024. If the plan is accepted, the Staff may grant the Company an extension period of up to 180 calendar days from the date of the Notice to evidence compliance. There can be no assurance that the Company will be able to regain compliance with the continued listing requirements or that the Staff will grant the Company a further extension of time to regain compliance. If the Staff does not accept the Company’s plan or if the Company is unable to regain compliance within any extension period granted by the Staff, the Company’s common stock will be subject to delisting. In the event the Company receives notice that the Company’s common stock is being delisted, Nasdaq’s rules permit the Company to appeal the delisting determination by the Staff to a hearings panel.

Financial Operations Overview

Revenues

To date, we have not generated any revenue from product sales and do not expect to generate any revenue from product sales in the near future. Our revenues have been primarily derived from our collaboration, research and license agreements as well as grants awarded by government agencies.

We have completed research and development services under the grant agreements and do not expect to recognize any revenue during 2024.

Operating Expenses

Research and Development Expenses

Research and development expenses represent costs incurred in connection with the discovery, research, preclinical and clinical development, and manufacture of our product candidates. We recognize all research and development costs as they are incurred. Research and development expenses consist primarily of the following:

---

Subject to receiving adequate funding, we expect our research and development expenses to increase in the future as we advance our product candidates into and through clinical trials and pursue regulatory approvals, which will require a significant investment in costs of clinical trials, regulatory support and contract manufacturing. In addition, we continue to evaluate opportunities to acquire or in-license other product candidates and technologies, which may result in higher research and development expenses due to license fee and/or milestone payments, as well as added clinical development costs.

As we are working on multiple research and development programs at any one time, we track our external expenses by the stage of program, clinical or preclinical. However, our internal expenses, including unallocated costs, personnel costs and infrastructure costs, are not directly related to any one program and are deployed across multiple programs. As such, we do not track internal expenses on a specific program basis.

The process of conducting clinical trials necessary to obtain regulatory approval is costly and time consuming. We may never succeed in timely developing and achieving regulatory approval for our product candidates. The probability of success of our product candidates may be affected by numerous factors, including clinical data, competition, manufacturing capability and commercial viability. As a result, we are unable to determine the duration and completion costs of our development projects or when and to what extent we will generate revenue from the commercialization and sale of any of our future product candidates.

General and Administrative Expenses

General and administrative expenses consist primarily of employee-related expenses, including salaries, benefits and stock-based compensation for personnel in executive, finance and accounting, and other administrative functions, as well as fees paid for legal, accounting and tax services, consulting fees and facilities costs not otherwise included in research and development expenses. Legal costs include general corporate legal fees and patent costs. We also incur expenses to operate as a public company, including expenses related to compliance with the rules and regulations of the SEC and Nasdaq, additional insurance, investor relations and other administrative expenses and professional services. Subject to receiving adequate funding, we expect our general and administrative expenses to be lower in 2024 as a result of the corporate restructuring announced in February 2024.

Other (Expense) Income

Interest Income

Interest income consists of interest earned on short-term money market accounts.

Interest Expense

Interest expense consists of interest charged on outstanding invoices and outstanding borrowings under several notes payable agreements.

Change in Fair Value Measurement of Rights from Private Placement

Change in fair value of other asset relates to the remeasurement of the rights from Private Placement that we determined was a derivative, which required the asset to be accounted for at fair value. Until settlement, the rights from Private Placement is remeasured at fair value at each reporting period with the changes in fair value recorded in the statement of operations. As of June 30, 2024, the rights from Private Placement was deemed to have no value as the second closing of the Private Placement was not expected to occur, and therefore the rights from Private Placement was written off and recorded in the statement of operations.

 

Change in Fair Value Measurement of Notes Payable

Change in fair value of notes payable relates to the remeasurement of the notes payable that we elected to account for under the fair value option. Until settlement, these notes payable are remeasured at fair value at each reporting period with the changes in fair value recorded in the statement of operations.

---

Other (Expense) Income, Net

Other (expense) income, net consists of interest income and other items that are of a non-recurring nature and primarily relate to items that are immaterial.

Net (Loss) Income Attributable to Noncontrolling Interest

Net (loss) income attributable to noncontrolling interest reflects investors’ share of net (loss) income in our majority owned subsidiary.

Revenues

 

Licensing revenues were zero for the three and six months ended June 30, 2024 and $5.0 million for the three and six months ended June 30, 2023. The licensing revenues in 2023 were due to the achievement of a development milestone pursuant to the Merck Neuromuscular License Agreement.

 

Collaboration revenues were zero for the three months ended June 30, 2024 and $161,000 for the three months ended June 30, 2023 and were zero for the six months ended June 30, 2024 and $442,000 for the six months ended June 30, 2023 as a result of research services provided in 2023 under the Merck Neuromuscular License Agreement pursuant to which the Company became a successor in interest in connection with the Merger. Upon completion of the Merger, we had $442,000 in deferred revenue under the Merck Neuromuscular License Agreement. As of December 31, 2023, we have completed the project services and had zero in deferred revenue under the Merck Neuromuscular License Agreement. We do not expect to earn any revenue from this license in 2024.

Research and Development Expenses

The following table summarizes our research and development expenses by program and category for the periods presented:

 

		Three Months Ended June 30,												Six Months Ended June 30,
		2024				2023				Change				2024				2023				Change

Total research and development expenses		$	1,001			$	2,710			$	(1,709	)		$	3,727			$	5,553			$	(1,826	)

 

Research and development expenses were $1.0 million for the three months ended June 30, 2024 and $2.7 million for the three months ended June 30, 2023 and decreased by $1.7 million, or 63%. The decrease in direct external program expenses of $1.1 million was primarily due to lower activities for KVA12123, our lead product candidate, as we curtailed the clinical trial due to failure to receive funding in April 2024 as expected. The decrease in our internal and unallocated research and development expenses of $605,000 was primarily due to lower personnel-related costs due to lower headcount and lower facilities allocations expense as we transitioned to clinical trials in 2023 and ceased using our laboratory space.

 

Research and development expenses were $3.7 million for the six months ended June 30, 2024 and $5.6 million for the six months ended June 30, 2023 and decreased by $1.8 million, or 33%. The decrease in direct external program expenses of $972,000 was primarily due to lower activities for KVA12123, our lead product candidate, and ALS program expenses incurred to complete project services in 2023 under the Merck Neuromuscular License Agreement, partially offset by higher costs for CD27 due to licensing costs. The decrease in our internal and unallocated research and development expenses of $854,000 was primarily due to lower facilities allocations expense as we transitioned to clinical trials in 2023 and ceased using our laboratory space and lower personnel-related costs due to lower headcount. Subject to receiving adequate funding, we expect our direct external program expenses to increase for the remainder of 2024 as we enroll additional patients in our clinical trials of KVA12123.

General and Administrative Expenses

General and administrative expenses were $1.6 million for the three months ended June 30, 2024 and $3.4 million for the three months ended June 30, 2023 and decreased by $1.8 million, or 54%. This decrease was primarily due to a decrease in personnel costs of $1.8 million and other administrative expenses of $71,000. Personnel costs decreased primarily due to lower stock-based compensation of $1.2 million as the result of stock-based compensation expense related to RSUs with performance conditions for the three months June 30, 2023 and lower salaries and benefits of $536,000 due to lower headcount in 2024 as compared to 2023.

General and administrative expenses were $5.3 million for the six months ended June 30, 2024 and $7.4 million for the six months ended June 30, 2023 and decreased by $2.1 million, or 28%. This decrease was primarily due to a decrease in personnel costs of $2.3 million, partially offset by an increase in other administrative expenses of $224,000. Personnel costs decreased primarily due to lower stock-based compensation of $1.8 million as the result of stock-compensation expense related to RSUs with performance conditions for the six months ended June 30, 2023 and lower salaries and benefits of $501,000 due to lower headcount in 2024 as compared to 2023. We expect our general and administrative expenses to continue to be lower than 2023 as the result of lower headcount as compared to 2023 and other cost-reduction measures implemented to preserve cash.

 

Other Income and expense, net

Interest Income

Interest income was $16,000 for the three months ended June 30, 2024 and $67,000 for the three months ended June 30, 2023 and decreased by $51,000. Interest income was $64,000 for the six months ended June 30, 2024 and $121,000 for the six months ended June 30, 2023 and decreased by $57,000. Interest income decreased due to lower balances in interest-bearing accounts during 2024.

 

Interest Expense

Interest expense was $32,000 for the three months ended June 30, 2024 and $21,000 for the three months ended June 30, 2023 and increased by $11,000. Interest expense was $74,000 for the six months ended June 30, 2024 and $44,000 for the six months ended June 30, 2023 and increased by $30,000. Interest expense increased primarily due to interest on outstanding vendor invoices.

---

Change in Fair Value Measurement of Private Placement

Change in fair value of other asset was zero for the three months ended June 30, 2024 and a gain of $1.2 million for the three months ended June 30, 2023. Change in fair value of other asset was a loss of $3.8 million for the six months ended June 30, 2024 and a gain of $1.2 million for the six months ended June 30, 2023. We determined the fair value of the rights from Private Placement to be zero as of March 31, 2024 as the second closing of the Private Placement did not occur in April 2024 as expected. As a result, we wrote off the balance of the rights from Private Placement during the three months ended March 31, 2024.

Going Concern and Capital Resources

 

Exploring Strategic Alternatives

 

We require substantial additional capital to sustain our operations and pursue our growth strategy, including the development of our product candidates. We are exploring strategic alternatives that may include, but are not limited to, sale of assets of the Company, a sale of the Company, licensing of assets, a merger, liquidation or other strategic action. If a strategic process is unsuccessful, the Board may decide to pursue a liquidation or obtain relief under the US Bankruptcy Code. These factors raise substantial doubt about our ability to continue as a going concern.

 

Sources of Liquidity

Since our inception through June 30, 2024, our operations have been financed primarily by net cash proceeds from the sale and issuance of our common stock and borrowings under notes payable. We have also received upfront and milestone payments from our license agreements. As of June 30, 2024, we had $900,000 in cash and an accumulated deficit of $178.6 million. Subject to receiving adequate funding, we expect that our operating expenses will increase, and, as a result, anticipate that we will continue to incur increasing losses for the foreseeable future. Therefore, we will need to raise additional capital to fund our operations, which may be through the issuance of additional equity or through borrowings.

 

In July 2024, we received a $5.0 million Exclusivity Payment from TuHURA in connection with the TuHURA Agreement and are negotiating a Potential Transaction (as defined in the TuHURA Agreement) with TuHURA.

Future Funding Requirements

Our revenues to date have been primarily derived from our collaboration, research and license agreements as well as grants awarded by government agencies. We, however, have not generated any revenue from product sales, and do not know when, or if, we will generate any revenue from product sales. We do not expect to generate any revenue from product sales unless and until we obtain regulatory approval of and commercialize any of our product candidates. At the same time, we expect our expenses to increase in connection with our ongoing development activities, particularly as we continue the research, development and clinical trials of, and seeks regulatory approval for, our product candidates. In addition, subject to obtaining regulatory approval of any of our product candidates, we anticipate that we will need substantial additional funding in connection with our continuing operations. We plan to continue to fund our operations and capital requirements through equity and/or debt financing, but there are no assurances that we will be able to raise sufficient amounts of funding in the future on acceptable terms, or at all.

Our future funding requirements will depend on many factors, including:

As of June 30, 2024, we had cash of $900,000, and there is substantial doubt about our ability to continue as a going concern. Based on our current operating plans, we do not have sufficient cash and cash equivalents to fund our operating expenses and capital expenditures for at least the next 12 months from the filing date of this Quarterly Report on Form 10-Q.

---

We are exploring strategic alternatives that may include, but are not limited to, sale of assets of the Company, a sale of the Company, licensing of assets, a merger, liquidation or other strategic action.

 

In July 2024, we received a $5.0 million Exclusivity Payment from TuHURA in connection with the TuHURA Agreement and are negotiating a Potential Transaction (as defined in the TuHURA Agreement) with TuHURA.

 

We may seek additional funds through equity or debt financings or through collaborations, licensing transactions or other sources that may be identified through our strategic process. However, there can be no assurance that we will be able to complete any such transactions on acceptable terms or otherwise. The failure to obtain sufficient funds on commercially acceptable terms when needed would have a material adverse effect on our business, results of operations, and financial condition. These factors raise substantial doubt about our ability to continue as a going concern.

 

We do not currently have any commitments for future funding or additional capital. As noted above, the investors failed to fulfill their contractual obligation to consummate the Private Placement. We are pursuing litigation or seeking other settlements against the investors for the failure to fund. Due to the lack of commitments for future funding or additional capital, we have paused or significantly scaled back the development or commercialization of our future product candidates or other research and development initiatives. If we are unable to complete a strategic transaction or raise additional capital in sufficient amounts, we will not be able to continue our business and we may need to file for bankruptcy protection.

Cash Flows

The following table summarizes our cash flows for the periods indicated:

 

		Six Months Ended June 30,
		2024				2023
		(in thousands)
Net cash provided by (used in):
Operating activities		$	(5,234	)		$	(11,905	)
Investing activities			—				303
Financing activities			351				6,229
Net change in cash and cash equivalents		$	(4,883	)		$	(5,373	)

 

Operating Activities

Cash used in operating activities for the six months ended June 30, 2024 was $5.2 million, consisting of a net loss of $12.9 million, partially offset by noncash charges of $5.6 million and a change in other net operating assets and liabilities of $2.1 million. The noncash charges primarily consisted of a $3.8 million change in fair value of rights from Private Placement, $846,000 in stock-based compensation, $469,000 in common stock issued for services and $403,000 noncash operating lease expense. Our change in net operating assets and liabilities primarily resulted from an increase in accounts payable and accrued liabilities of $2.8 million and prepaid expenses and other current assets of $236,000, partially offset by a decrease in operating lease liability of $466,000.

Cash used in operating activities for the six months ended June 30, 2023 was $11.9 million, consisting of a net loss of $6.1 million and a change in other net operating assets and liabilities of $7.8 million, partially offset by noncash charges of $2.0 million. Our change in net operating assets and liabilities primarily resulted from a $5.0 million increase in license receivable and decreases in accrued expenses and other current liabilities of $1.6 million, accounts payable of $0.5 million, deferred revenue of $0.4 million, operating lease liability of $0.4 million and prepaid expenses and other current assets of $0.2 million. The noncash charges primarily consisted of $2.9 million in stock-based compensation and $0.4 million noncash operating lease expense, partially offset by a $1.2 million change in fair value of other asset and $0.1 million gain on disposal of fixed assets.

Investing Activities

Cash provided by investing activities was zero for the six months ended June 30, 2024 and $303,000 for the six months ended June 30, 2023 consisting of cash received from the sale of certain property and equipment.

Financing Activities

Cash provided by financing activities was $351,000 for the six months ended June 30, 2024 primarily related to proceeds of $500,000 from the issuance of our common stock, partially offset by repayment of a note payable of $150,000.

Cash provided by financing activities for the six months ended June 30, 2023 was $6.2 million, primarily related to net proceeds of $5.5 million from the Company’s registered direct offering which took place in April 2023 and $0.8 million from the issuance of our common stock to investors pursuant to the Open Market Sale AgreementSM, dated February 10, 2023, by and between the Company and Jefferies LLC.

 

Debt Obligations

Notes Payable

As of June 30, 2024, we had outstanding notes payable in an aggregate principal amount of $629,000 at an interest rate of 6%. Notes payable of $379,000 matured, but were not paid, as of June 30, 2024. The remaining note payable of $250,000 matures on July 31, 2024.

---

See Note 5 to our consolidated financial statements included in this Quarterly Report for additional information regarding our notes payable.

Other Contractual Obligations and Commitments

Our cash requirements greater than 12 months are related to other contractual obligations and commitments related to license agreements.

We have entered into a number of strategic license agreements pursuant to which we have acquired rights to specific assets, technology and intellectual property. In accordance with these agreements, we are obligated to pay, among other items, future contingent payments that are dependent upon future events such as our achievement of certain development, regulatory and commercial milestones royalties, and sublicensing revenue in the future, as applicable. As of June 30, 2024, the timing and likelihood of achieving the milestones and generating future product sales, and therefore payments that may become payable to these third parties, are uncertain.

We leased office and laboratory space for our corporate headquarters in Seattle, Washington under a lease agreement that expired on July 31, 2024. This lease was not renewed and no other facility lease was entered into as the Company employees are working remotely. As of June 30, 2024, undiscounted future minimum lease payments of $81,000 remain pursuant to the lease agreement.

In addition, we enter into agreements in the normal course of business with various third parties for preclinical research studies, clinical trials, testing and other research and development services. Such agreements generally provide for termination upon notice, although obligate us to reimburse vendors for any time or costs incurred through the date of termination.

Critical Accounting Estimates

Our management’s discussion and analysis of financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of these consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities and expenses, and related disclosures. Our estimates are based on historical experience and on various assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the recording of expenses that are not readily apparent from other sources. Actual results may differ materially from these estimates. Our critical accounting estimates used in the preparation of our financial statements for the three and six months ended June 30, 2024 were consistent with those in Part II, Item 7 of our Annual Report on Form 10-K.

 

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

We are a smaller reporting company, as defined in Rule 12b-2 under the Exchange Act, for this reporting period and are not required to provide the information required under this item.

Item 4. Controls and Procedures.

 

Evaluation of Disclosure Controls and Procedures

Prior to completion of the Merger, we were a private company and had limited accounting and financial reporting personnel and other resources with which to address our internal controls and related procedures. In connection with the audit of our financial statements for the years ended December 31, 2023 and 2022, our management and our independent registered public accounting firm identified material weaknesses in our internal control over financial reporting. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting as defined under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and by the Public Company Accounting Oversight Board (United States), such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. The material weaknesses for the year ended December 31, 2023 relate to accounting for complex financial instruments related to the derivative asset, accounting for offering costs and accounting for allocated facilities costs. The material weakness for the year ended December 31, 2022 relates to accounting for complex financial instruments related to warrants issued to certain existing stockholders. The material weaknesses are still present and have not been remediated.

 

Our management, with the participation of our President and Chief Financial Officer, has 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 the end of the fiscal quarter ended June 30, 2024. Based on this evaluation and for the reasons set forth above, our President and Chief Financial Officer have concluded that our disclosure controls and procedures were not effective as of June 30, 2024.

 

We are in the process of implementing measures designed to improve our internal control over financial reporting to remediate the material weaknesses. For example, we began to address the material weaknesses by implementing certain Sarbanes-Oxley controls during the first half of 2022. In October 2022, we hired a Chief Financial Officer to enhance internal controls and address the material weaknesses and other control deficiencies identified during the 2021 audit of the financial statements. We have designed and implemented improved processes and internal controls, including ongoing senior management review and audit committee oversight. We have also implemented and upgraded accounting and reporting systems to improve accounting and financial reporting processes. Additionally, we have enhanced, developed and implemented formal

---

policies, processes and documentation procedures relating to our financial processes, including the oversight of third-party service providers. Our actions are subject to ongoing executive management review and will also be subject to audit committee oversight.

 

Notwithstanding the material weaknesses in internal control over financial reporting described above, our management has concluded that our consolidated financial statements included in this Quarterly Report on Form 10-Q are fairly stated in all material respects in accordance with accounting principles generally accepted in the United States of America.

Changes in Internal Control over Financial Reporting

Except as disclosed above, there has been no change in our internal control over financial reporting that occurred during the second quarter of 2024 that has materially affected, or is reasonably likely to materially affect, our internal control over current or future financial reporting.

PART II - OTHER INFORMATION

Item 1. Legal Proceedings.

On March 20, 2024, Kineta filed a complaint in the Court of Chancery of the State of Delaware against Growth & Value Development Inc. (“GVDI”), alleging breach of contract in connection with GVDI’s recent repudiation of its obligation to provide a substantial tranche of funding for Kineta as required under the Securities Purchase Agreement. The complaint provides that Kineta will seek specific performance of GVDI’s obligations under the Securities Purchase Agreement and damages equal to the amount of the unpaid funding and any damages resulting from GVDI’s breach.

 

On May 30, 2024, Kineta filed a complaint in the Court of Chancery of the State of Delaware against Myron Wolff, alleging breach of contract in connection with Myron Wolff’s recent repudiation of its obligation to provide a substantial tranche of funding for Kineta as required under the Securities Purchase Agreement. The complaint provides that Kineta will seek specific performance of Myron Wolff’s obligations under the Securities Purchase Agreement and damages equal to the amount of the unpaid funding and any damages resulting from Myron Wolff’s breach.

 

Except as disclosed in the preceding paragraphs, Kineta is currently not a party to any other material legal proceedings. From time to time, however, Kineta may be a party to litigation or subject to claims incident to the ordinary course of business. Although the results of litigation and claims cannot be predicted with certainty, Kineta currently believes that the final outcome of these ordinary course matters will not have a material adverse effect on Kineta’s business. Regardless of the outcome, litigation can have an adverse impact on Kineta because of defense and settlement costs, diversion of management resources and other factors.

Item 1A. Risk Factors.

 

Except as set forth below, there have been no material changes to our risk factors included in our 2023 Annual Report on Form 10-K. The following risk factor, together with the risks and uncertainties referenced above, should be considered carefully before making an investment decision. Any of these factors could result in a significant or material adverse effect on our results of operations or financial condition. Additional risk factors not presently known to us or that we currently deem immaterial may also impair our business or results of operations. We may disclose changes to such risk factors or disclose additional risk factors from time to time in our future filings with the SEC.

 

The second closing of the Private Placement did not close as anticipated, and Kineta currently does not have any commitments for future funding or additional capital.

As previously disclosed, we entered into the Securities Purchase Agreement with certain investors to sell shares of our common stock to such investors in the Private Placement. The first closing of the Private Placement occurred on December 16, 2022 and we issued 649,346 shares of our common stock and received net proceeds of $7.4 million. The second closing of the Private Placement for an aggregate purchase price of $22.5 million was scheduled to occur on April 15, 2024, however, the investors failed to fulfill their contractual obligation to fund and the second closing did not occur. Kineta does not have any commitments for future funding or additional capital. Kineta is pursuing litigation or seeking other settlements against the investors for the failure to fund. Due to the lack of commitments for future funding or additional capital, Kineta has paused or significantly scaled back the development or commercialization of its future product candidates or other research and development initiatives. If Kineta is unable to complete a strategic transaction or raise additional capital in sufficient amounts, Kineta will not be able to continue its business and the Company may need to file for bankruptcy protection.

 

Kineta identified conditions and events that raise substantial doubt about its ability to continue as a going concern, Kineta needs substantial additional funding, and if Kineta is unable to raise capital when needed or on favorable terms, its business, financial condition, and results of operation could be materially and adversely affected.

 

Kineta may be forced to wind-down its operations if it is unable to consummate a strategic transaction and/or obtain sufficient funding.

 

As of June 30, 2024, Kineta had $900,000 in cash, and there is substantial doubt about its ability to continue as a going concern. In July 2024, Kineta received cash proceeds of $5.0 million from TuHURA, however, based on Kineta’s current operating plans, Kineta does not have sufficient cash and cash equivalents to fund its operating expenses and capital expenditures for at least the next 12 months from the filing date of this Quarterly Report on Form 10-Q.

 

Kineta is exploring strategic alternatives that may include, but are not limited to, sale of assets of the Company, a sale of the Company, licensing of assets, a merger, liquidation or other strategic action.

 

Kineta may seek additional funds through equity or debt financings or through collaborations, licensing transactions or other sources that may be identified through the Company’s strategic process. However, there can be no assurance that Kineta will be able to complete any such transactions on acceptable terms or otherwise. The failure to obtain sufficient funds on commercially acceptable terms when needed would have a material adverse effect on Kineta’s business, results of operations, and financial condition. These factors raise substantial doubt about Kineta’s ability to continue as a going concern.

 

Kineta does not currently have any commitments for future funding or additional capital. As noted above, the investors failed to fulfill their contractual obligation to consummate the Private Placement. The Company is pursuing litigation or seeking other settlements against the investors

---

for the failure to fund. Due to the lack of commitments for future funding or additional capital, Kineta has paused or significantly scaled back the development or commercialization of its future product candidates or other research and development initiatives. If Kineta is unable to complete a strategic transaction or raise additional capital in sufficient amounts, Kineta will not be able to continue its business and the Company may need to file for bankruptcy protection.

 

We are currently not in compliance with Nasdaq’s continued listing requirements. If we are unable to comply with Nasdaq’s continued listing requirements, our common stock could be delisted, which could affect the price of our common stock and liquidity and reduce our ability to raise capital.

 

Nasdaq Bid Price Deficiency Letter

 

Our common stock is currently listed on The Nasdaq Capital Market. The Nasdaq Capital Market has established certain quantitative criteria and qualitative standards that companies must meet to remain listed for trading on this market.

 

On April 18, 2024, the Company received the Notice from the Listing Qualifications Department of Nasdaq stating that Kineta was not in compliance with Nasdaq Listing Rule 5550(b)(2) because Kineta did not maintain a minimum closing bid price of the Company’s common stock of at least $1.00 per share for the last 30 consecutive business days. The Notice has no immediate effect on the listing or trading of the Company’s securities.

 

The Company has 180 calendar days from the date of the Notice, or until October 15, 2024, to regain compliance. If the Company is not deemed in compliance before the expiration of the 180 day compliance period, it will be afforded an additional 180 day compliance period, or until April 13, 2025, provided that on the 180th day of the first compliance period it meets the applicable market value of publicly held shares requirement for continued listing and all other applicable standards for initial listing on The Nasdaq Capital Market (except the bid price requirement) based on the Company’s most recent public filings and market information and provides written notice to Nasdaq of its intention to cure this deficiency during the second compliance period.

 

The Company intends to monitor the bid price of the Company’s listed securities and may, if appropriate, consider available options to regain compliance with the bid price requirement. There can be no assurance that the Company will be able to regain compliance with the bid price requirement.

 

Any delisting of our common stock could adversely affect the market liquidity of our common stock and the market price of our common stock could decrease. In addition, delisting of our common stock could result in the loss of confidence by investors and adversely affect our ability to raise capital on terms acceptable to us, or at all.

 

Nasdaq Stockholders’ Equity Deficiency Letter

 

On May 23, 2024, the Company received the Notice from the Staff informing the Company that it no longer complies with the requirement under Nasdaq Listing Rule 5550(b)(1) to maintain a minimum of $2,500,000 in stockholders’ equity for continued listing on Nasdaq because the Company reported stockholders’ equity of negative $6,243,000 in its Quarterly Report on Form 10-Q for the period ended March 31, 2024, and, as of the date of the Notice, the Company did not meet the alternatives of market value of listed securities or net income from continuing operations. The Notice has no immediate effect on the listing or trading of the Company’s securities.

 

The Company timely submitted the compliance plan to the Staff on July 8, 2024. If the plan is accepted, the Staff may grant the Company an extension period of up to 180 calendar days from the date of the Notice to evidence compliance. There can be no assurance that the Company will be able to regain compliance with the continued listing requirements or that the Staff will grant the Company a further extension of time to regain compliance. If the Staff does not accept the Company’s plan or if the Company is unable to regain compliance within any extension period granted by the Staff, the Company’s common stock will be subject to delisting. In the event the Company receives notice that the Company’s common stock is being delisted, Nasdaq’s rules permit the Company to appeal the delisting determination by the Staff to a hearings panel.

 

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

 

None.

---

Item 3. Defaults Upon Senior Securities.

None.

Item 4. Mine Safety Disclosures.

Not applicable.

 

Item 5. Other Information.

 

During the three months ended June 30, 2024, none of our directors or officers informed us of the adoption, modification or termination of a “Rule 10b5-1 trading arrangement” or “non-Rule 10b5-1 trading arrangement,” as those terms are defined in Regulation S-K, Item 408.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Liquidity	1. Organization and Liquidity Description of Business   Kineta, Inc. (together with its subsidiaries, “Kineta” or the “Company”) is headquartered in Mercer Island, Washington.   The Company is a clinical-stage biotechnology company with a mission to develop next-generation immunotherapies that transform patients’ lives. Kineta has leveraged its expertise in innate immunity and is focused on discovering and developing potentially differentiated immunotherapies that address the mechanisms of cancer immune resistance. Kineta Chronic Pain, LLC (“KCP”) was formed to develop new innovative therapies for pain management. Kineta Viral Hemorrhagic Fever, LLC (“KVHF”) was formed to develop a direct acting anti-viral therapy for the treatment of emerging diseases. As of June 30, 2024 and December 31, 2023, the Company owned a majority interest of the outstanding issued equity of KCP and all of the outstanding issued equity of KVHF. On November 30, 2023, the Company dissolved KVHF and assumed all of the outstanding issued equity. As of June 30, 2024, the Company owns a majority interest of the outstanding issued equity of KCP. Private Placement On December 16, 2022, Yumanity Therapeutics, Inc. (“Yumanity”) completed its previously announced merger transaction with Kineta Operating, Inc. (formerly Kineta, Inc.) (“Private Kineta”) in accordance with the terms of the Agreement and Plan of Merger, dated as of June 5, 2022, as amended on December 5, 2022 (the “Merger Agreement”), by and among Yumanity, Private Kineta and Yacht Merger Sub, Inc., a wholly-owned subsidiary of Yumanity (“Merger Sub”), pursuant to which Merger Sub merged with and into Private Kineta, with Private Kineta surviving such merger as a wholly-owned subsidiary of Yumanity (the “Merger”). In connection and concurrently with the execution of the Merger Agreement, the Company entered into a financing agreement, dated as of June 5, 2022, as amended on October 24, 2022, December 5, 2022, March 29, 2023, May 1, 2023, July 21, 2023 and October 13, 2023 (such financing agreement, as amended, the “Securities Purchase Agreement”), to sell shares of the Company’s common stock in a private placement (the “Private Placement”). The first closing of the Private Placement occurred on December 16, 2022, and the Company issued 649,346 shares of its common stock and received net proceeds of $7.4 million. The second closing of the Private Placement for an aggregate purchase price of $22.5 million was expected to occur on April 15, 2024, however, the investors failed to fulfill their contractual obligation to fund and the second closing did not occur. Going Concern and Capital Resources The Company has incurred recurring net losses and negative cash flows from operations since inception and, as of June 30, 2024, had an accumulated deficit of $178.6 million. The net loss attributable to the Company was $12.9 million for the six months ended June 30, 2024. As of June 30, 2024, the Company had unrestricted cash of $900,000, and there is substantial doubt about its ability to continue as a going concern. Based on Kineta’s current operating plans, Kineta does not have sufficient cash and cash equivalents to fund its operating expenses and capital expenditures for at least the next 12 months from the filing date of this Quarterly Report on Form 10-Q.   Kineta is exploring strategic alternatives that may include, but are not limited to, sale of assets of the Company, a sale of the Company, licensing of assets, a merger, liquidation or other strategic action.   On July 3, 2024 (the “Effective Date”), the Company entered into an exclusivity and right of first offer agreement (the “TuHURA Agreement”) by and between the Company and TuHURA Biosciences, Inc., a Delaware corporation (“TuHURA”).   Pursuant to the TuHURA Agreement, among other things, Kineta has granted TuHURA an exclusive right to acquire Kineta’s worldwide patents, patent rights, patent applications, product and development program assets, technical and business information, and other rights and assets associated with and derived from its development program related to KVA12123, the Company’s VISTA blocking immunotherapy, during the period commencing as of the Effective Date and continuing through the first to occur of (a) the execution of any Definitive Agreement (as defined in the TuHURA Agreement) with respect to a Potential Transaction (as defined in the TuHURA Agreement) by TuHURA or one or more of its affiliates and (b) 11:59 PM Eastern Time on October 1, 2024, subject to extension as noted in the following sentence (the “Exclusivity Period”). In the event that the Parties are engaged in good faith discussions regarding a Potential Transaction on the date on which the Exclusivity Period (or any renewal thereof) is scheduled to expire and TuHURA has not yet closed the transactions contemplated by that previously announced agreement and plan of merger by and among TuHURA, Kintara Therapeutics, Inc. (“Kintara”) and Kayak Mergeco, Inc., a wholly-owned subsidiary of Kintara, then on such date, the Exclusivity Period shall automatically renew for an additional ten (10) day period (a “Renewal Period”) (up to a total of two (2) renewal periods for an aggregate of twenty (20) days).   In consideration for Kineta’s compliance with its obligations set forth in the TuHURA Agreement, TuHURA paid to Kineta $5.0 million (the “Exclusivity Payment”) in July 2024. No later than two (2) business days after a Renewal Period has started (to be confirmed in writing by both Parties), TuHURA shall pay an additional $150,000 as an additional Exclusivity Payment, in an amount not to exceed $300,000 for the two (2) available Renewal Periods. The Exclusivity Payment will be credited against the initial cash consideration that may be payable to Kineta pursuant to any Definitive Agreement (if any) between Kineta and TuHURA and/or its affiliates with respect to a Potential Transaction.   Kineta may seek additional funds through equity or debt financings or through collaborations, licensing transactions or other sources that may be identified through the Company’s strategic process. However, there can be no assurance that Kineta will be able to complete any such transactions on acceptable terms or otherwise. The failure to obtain sufficient funds on commercially acceptable terms when needed would have a material adverse effect on Kineta’s business, results of operations, and financial condition. These factors raise substantial doubt about Kineta’s ability to continue as a going concern.   Kineta does not currently have any commitments for future funding or additional capital. As noted above, the investors failed to fulfill their contractual obligation to consummate the Private Placement. The Company is pursuing litigation or seeking other settlements against the investors for the failure to fund. Due to the lack of commitments for future funding or additional capital, Kineta has paused or significantly scaled back the development or commercialization of its future product candidates or other research and development initiatives. If Kineta is unable to complete a strategic transaction or raise additional capital in sufficient amounts, Kineta will not be able to continue its business and the Company may need to file for bankruptcy protection. Geopolitical Developments Geopolitical developments, such as the current conflict in Ukraine and the conflict in Israel and the Gaza Strip or deterioration in the bilateral relationship between the United States and China, may impact government spending, international trade and market stability, and cause weaker macro-economic conditions. The impact of these developments, including any resulting sanctions, export controls or other restrictive actions that may be imposed against governmental or other entities in, for example, Russia, have in the past contributed and may in the future contribute to disruption, instability and volatility in the global markets, which in turn could adversely impact the Company’s operations and weaken the Company’s financial results. Certain political developments may also lead to uncertainty to regulations and rules that may materially affect the Company’s business.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies   Unaudited Interim Financial Information The unaudited condensed consolidated balance sheet as of December 31, 2023 was derived from the Company’s audited financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America (“U.S. GAAP”). The accompanying unaudited condensed consolidated financial statements, as of June 30, 2024 and for the three and six months ended June 30, 2024, are unaudited and have been prepared by the Company pursuant to the rules and regulations of the SEC for interim financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. The Company believes that the disclosures are adequate to make the information presented not misleading. There have been no changes to the Company’s significant accounting policies described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, filed with the SEC on March 21, 2024 (the “2023 Annual Report on Form 10-K”). These unaudited condensed financial statements should be read in conjunction with the Company’s audited financial statements and the notes thereto for the year ended December 31, 2023 included in the 2023 Annual Report on Form 10-K. In the opinion of management, all adjustments, consisting only of normal recurring adjustments necessary for a fair statement of the Company’s condensed consolidated financial position as of June 30, 2024 and condensed consolidated results of operations and cash flows for the three and six months ended June 30, 2024 and 2023 have been made. The results of operations for the three and six months ended June 30, 2024 are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2024.   Basis of Presentation and Consolidation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. GAAP and applicable SEC rules. The condensed consolidated financial statements include all accounts of the Company, its majority owned subsidiary KCP, and its wholly owned subsidiary, KVHF. All intercompany transactions and balances have been eliminated upon consolidation. Noncontrolling interest in the accompanying condensed consolidated financial statements represents the proportionate share of equity which is not held by the Company. Net income (loss) of the non-wholly owned consolidated subsidiary is allocated to the Company and the holder(s) of the noncontrolling interests in proportion to their percentage ownership considering any preferences specific to the form of equity of the subsidiaries. Revenue Recognition Licensing Revenues   In June 2023, the Company achieved a development milestone pursuant to the Merck Neuromuscular License Agreement (defined below), which triggered a $5.0 million payment. This collaboration focused on the discovery and development of novel candidates for the treatment of amyotrophic lateral sclerosis (“ALS”). Merck will continue to advance the research program for the ALS pipeline, one of the two pipeline programs licensed under the Merck Neuromuscular License Agreement. As a result, the Company is eligible to receive up to an additional $255.0 million in development milestones, sales milestones and royalties on net sales. Following this milestone, Merck will assume sole responsibility for all future development and commercialization for the ALS program. The Company recognized licensing revenues of zero for the three and six months ended June 30, 2024.The Company recognized one-time licensing revenue of $5.0 million for the three months ended June 30, 2023.   Collaboration Revenues   In connection with the Merger, the Company became the successor in interest to an exclusive license and research collaboration agreement (the “Merck Neuromuscular License Agreement”) with Merck to support research, development and commercialization of products for treatment of neuromuscular diseases, including amyotrophic lateral sclerosis. The Company recognizes revenue using the cost-to-cost method, which it believes best depicts the transfer of control to the customer. Under the cost-to-cost method, the extent of progress towards completion is measured based on the ratio of actual costs incurred to the total estimated costs expected upon satisfying the identified performance obligation. Under this method, revenue is recognized as a percentage of actual cost incurred to the estimated costs to complete. The Company recognized collaboration revenues of zero for the three and six months ended June 30, 2024. The Company recognized collaboration revenues of $161,000 for the three months ended June 30, 2023 and $442,000 for the six months ended June 30, 2023. As of June 30, 2023, the Company completed its project services under the Merck Neuromuscular License Agreement.     Net income (loss) per share Basic net income (loss) per common share is computed by dividing the net income (loss) by the weighted average number of shares of common stock outstanding for the period. Diluted net income (loss) per common share is computed by dividing net income (loss) by the weighted average number of common shares outstanding for the period, including potential dilutive common shares assuming the dilutive effect of outstanding common share equivalents. For the three and six months ended June 30, 2024 and the six months ended June 30, 2023, the Company reported a net loss and the diluted net loss per common share is the same as basic net loss per common share, since dilutive common shares are not assumed to have been issued if their effect is anti-dilutive. For the three months ended June 30, 2023, the diluted net income per common share was the same as basic net income per common share, as all potentially dilutive common share equivalents were determined to be anti-dilutive, using the treasury stock method.

Fair Value Disclosures [Abstract]
Fair Value Measurements	3. Fair Value Measurements The carrying amounts of the Company’s financial instruments, including cash, restricted cash, and accounts payable, approximate fair value due to the short-term nature of those instruments.   Rights from Private Placement   The Company determined that the rights from Private Placement was a derivative asset, which required the asset to be accounted for at fair value. As of March 31, 2024, the Company did not expect the second closing of the Private Placement to occur and as a result, the Company deemed the fair value of the rights from Private Placement to be zero. The Company recorded a loss in the fair value of Private Placement of zero for the three months ended June 30, 2024 and $3.8 million for the six months ended June 30, 2024, which is recorded in other income (expense) in the Statement of Operations.   The fair value as of June 30, 2023 was determined using a Monte Carlo simulation based on the contractual funding date of July 25, 2023, minimum contractual purchase price of $3.18 and historical stock prices. The significant unobservable inputs used in the fair value measurement as of June 30, 2023 were as follows: volatility of 73%, risk-free interest rate of 5.11% and funding probability of 75%, which resulted in a change in fair value of $1.2 million for the three and six months ended June 30, 2023, which is recorded in other income (expense) in the Statement of Operations. The fair value measurement as of June 30, 2023 was approximately $3.5 million. The following table provides a summary of the changes in the fair value of the rights from Private Placement measured using Level 3 inputs:       Six Months Ended June 30,       2024     2023       (in thousands)   Balance at beginning of period   $ 3,832     $ 2,250   Change in fair value of rights from Private Placement     (3,832 )     1,221   Balance at end of period   $ —     $ 3,471     2020 Notes   The Company elected the fair value option to account for the 2020 notes (as defined below) (see Note 5). During 2024, the Company did not obtain an independent valuation of the 2020 notes as they matured on July 31, 2024 and the fair value approximates the principal amount.   The 2020 notes were valued using a discounted cash flow model based on the contractual payment dates, a discount rate and the contractual maturity date. The significant unobservable inputs used in the fair value measurement of the 2020 notes as of June 30, 2023 were as follows: discount rate of 14.0% and contractual payment date of 1.0 year, which resulted in a fair value for the 2020 notes of $232,000. The following table provides a summary of the changes in the fair value of the 2020 notes payable measured using Level 3 inputs:       Six Months Ended June 30,       2024     2023       (in thousands)   Balance at beginning of period   $ 241     $ 219   Change in fair value of 2020 notes     9       13   Balance at end of period   $ 250     $ 232

The first closing of the Private Placement occurred on December 16, 2022, and the Company issued 649,346 shares of its common stock and received net proceeds of $7.4 million.

The other notes payable and Small Business Administration loan approximate their fair value because interest rates are at prevailing market rates. 2020 Notes In October 2020, the Company refinanced certain notes payable (the “2020 notes”), with an aggregate principal amount of $3.0 million with various investors, including one investor that is a related party. The interest rate was reduced on the 2020 notes from 16.0% to 6.0% from October 2020 until the earlier of (i) the Company raises at least $25.0 million in a single transaction or series of transactions after October 2020 and (ii) the original maturity dates (that is, various dates in the first quarter of 2022), after which the interest rate increases to 16.0%. The outstanding principal is due upon demand of the majority of the lenders with respect to (i) 50% on or after nine months after the original maturity date (or on or after various dates in the fourth quarter of 2022) and (ii) 50% on or after fifteen months after the original maturity date (or on or after various dates in the second quarter of 2023). The Company may repay the 2020 notes at any time without penalty. Upon bankruptcy the lender can accelerate all amounts due immediately.   In August 2022, the Company settled $1.4 million in outstanding principal and accrued interest by issuing 59,000 shares of the Company’s non-voting common stock at a 15% discount. The Company extended the maturity date for the remaining 2020 notes with a principal balance of $250,000 to July 31, 2024 and reduced the interest rate to 6%, which was accounted for as a modification. As the 2020 notes were valued pursuant to the fair value election, an immaterial gain was recognized upon extinguishment. The 2020 notes matured on July 31, 2024 and are payable anytime after the maturity date upon demand by the holder. Other Notes Payable The Company issued several other notes payable in 2019 and early 2020 at a 12.0% interest rate per annum, with the principal amounts due in full at maturity and interest due monthly or quarterly. The other notes payable were due to mature at various dates between December 2020 through early 2022. The other notes payable were amended in October 2020 to increase the interest rate to 13.0% and extend the maturity date to be on demand by a majority of the holders on or after April 7, 2022, which resulted in a modification of the other notes payable. The Company may prepay the other notes payable at any time without penalty. In April 2022, the Company extended the maturity date for the remaining other notes payable with a principal balance of $379,000 to June 30, 2024 and decreased the interest rate to 6.0% interest, which was accounted for as a modification. As the other notes payable approximated their fair value, no gain or loss was recognized upon extinguishment. The other notes payable matured on June 30, 2024 and are payable anytime after the maturity date upon demand by the holder. Small Business Administration Loan In August 2020, the Company received a U.S. Small Business Administration (“SBA”) loan of $150,000 at a 3.75% interest rate and maturing in August 2050. Repayments of principal are due monthly beginning in June 2027 and interest is due monthly. The Company repaid the SBA loan and accrued interest in April 2024.

This lease was not extended and no other facility lease was entered into as the Company's employees work remotely. The agreement, which required monthly lease payments, was subject to annual rent escalations during the lease term, and contained two five-year options to extend the lease term. In June 2020, the Company amended the lease agreement to reduce the leased space for the premises from approximately 22,064 square feet to approximately 14,870 square feet, which was accounted for as a lease modification and partial termination of the lease.   Under the lease agreement, the Company was required to pay certain operating costs, in addition to rent, such as common area maintenance, taxes and utilities. Such additional charges are considered variable lease costs and are recognized in the period in which they are incurred. Rent expense was $208,000 for the three months ended June 30, 2024 and variable costs were $151,000. Rent expense was $416,000 for the six months ended June 30, 2024 and variable costs were $302,000.

Under the first sublease agreement, which commenced in December 2017, the Company subleases approximately 1,850 square feet. In October 2020 the sublease expiration date was extended from December 2020 to December 2022. In September 2022, the sublease expiration date was extended from December 2022 to December 2023. In December 2023, the sublease expiration date was extended from December 2023 to July 2024.

Sublease income was $49,000 for the three months ended June 30, 2023 and $97,000 for the six months ended June 30, 2023. As of June 30, 2024, the total minimum rentals to be received under the remaining noncancelable sublease was $10,000.   Indemnification In the ordinary course of business, the Company enters into agreements that may include indemnification provisions. Pursuant to such agreements, the Company may indemnify, hold harmless and defend an indemnified party for losses suffered or incurred by the indemnified party. Some of the provisions will limit losses to those arising from third-party actions. In some cases, the indemnification will continue after the termination of the agreement. The maximum potential amount of future payments the Company could be required to make under these provisions is not determinable. The Company has not incurred material costs to defend lawsuits or settle claims related to these indemnification provisions. The Company has also entered into indemnification agreements with its directors and officers that may require the Company to indemnify its directors and officers against liabilities that may arise by reason of their status or service as directors or officers to the fullest extent permitted under the Delaware General Corporation Law. The Company currently has directors’ and officers’ insurance. Other Commitments The Company has various manufacturing, clinical, research and other contracts with vendors in the conduct of the normal course of its business. Such contracts are generally terminable with advanced written notice and payment for any products or services received by the Company through the effective time of termination and any noncancelable and nonrefundable obligations incurred by the vendor at the effective time of the termination. In the case of terminating a clinical trial agreement at a particular site, the Company would also be obligated to provide continued support for appropriate medical procedures at that site until completion or termination.

In connection with Dr. Iadonato’s departure, the Company entered into a separation and release agreement with Dr. Iadonato (the “Iadonato Separation Agreement”). Pursuant to the Iadonato Separation Agreement, Dr. Iadonato received payment equal to 80 hours of accrued but unused paid time off and two weeks worth of wages, which, in aggregate, is equal to $38,462. In exchange for the payments and other consideration under the Iadonato Separation Agreement, Dr. Iadonato provided the Company with a release, in favor of the Company, of any and all claims relating to his employment with the Company.   In connection with Ms. Kenny’s departure, the Company entered into a separation and release agreement with Ms. Kenny (the “Kenny Separation Agreement”).

Private Placement   The Private Placement (see Note 1) provides for the issuance of shares of the Company’s common stock in two closings, one of which occurred immediately following the closing of the Merger and one of which was expected to occur on April 15, 2024. The first closing of the Private Placement occurred on December 16, 2022 and the Company issued 649,346 shares of its common stock and received net proceeds of $7.4 million to investors that are related parties.   In connection with the Private Placement in December 2022, the Company issued 104,000 warrants to purchase shares of the Company’s non-voting common stock to investors in the Private Placement, each at an exercise price of $0.14, with exercise contingent upon the Merger closing and exercisable following the first closing of the Private Placement. The Company determined the contingent exercise provisions were indexed to the Company’s operations and the warrants qualified for equity classification.   The second closing of the Private Placement was expected to occur on April 15, 2024, however, the investors failed to fulfill their contractual obligation to fund and the second closing did not occur. Had the second closing of the Private Placement occurred, the Company would have been obligated to issue a number of shares of its common stock based on the aggregate purchase price of $22.5 million divided by the purchase price equal to (a) the VWAP, plus (b) 10% of the VWAP; provided, however, that the share purchase price shall be at least equal to the closing price of the Company’s common stock on March 29, 2023. The Company determined that its obligation to issue additional shares of its common stock in the second closing at a premium to the VWAP was a freestanding financial instrument and a future right, which is subject to fair value. Accordingly, at inception the future right was recorded as an other asset in the Company’s consolidated balance sheet at its fair value equal to 10% of the second closing amount, or $2.3 million. The remaining proceeds from the first closing were allocated to the shares of common stock issued in the first closing and to the warrants as such instruments are equity-classified. The future right was subject to remeasurement at each reporting date and the Company used the Monte Carlo simulation method to determine fair value of approximately $3.8 million as of December 31, 2023 and zero as of June 30, 2024 as at that time, the Company did not expect the second closing to occur. The Company incurred insignificant issuance costs related to the Private Placement.   Nasdaq Bid Price Deficiency Letter On April 18, 2024, the Company received written notice (the “Notice”) from the Listing Qualifications Department of The Nasdaq Stock Market LLC (“Nasdaq”) stating that the Company is not in compliance with Nasdaq Listing Rule 5550(a)(2) (the “Rule”) because the Company has not maintained a minimum closing bid price of the Company’s common stock of at least $1.00 per share for the last 30 consecutive business days. The Notice has no immediate effect on the listing or trading of the Company’s securities.   The Company has 180 calendar days from the date of the Notice, or until October 15, 2024, to regain compliance. If the Company is not deemed in compliance before the expiration of the 180 day compliance period, it will be afforded an additional 180-day compliance period, provided that on the 180th day of the first compliance period it meets the applicable market value of publicly held shares requirement for continued listing and all other applicable standards for initial listing on The Nasdaq Capital Market (except the bid price requirement) based on the Company's most recent public filings and market information and provides written notice to Nasdaq of its intention to cure this deficiency during the second compliance period.   Compliance can be achieved during any compliance period by meeting the applicable standard for a minimum of 10 consecutive business days during the applicable compliance period, unless Nasdaq exercises its discretion to extend this 10 day period as discussed in Rule 5810(c)(3)(H).   If the Company does not regain compliance with the bid price requirement within the compliance period, the Company’s common stock will be subject to delisting. In the event the Company receives notice that the Company’s common stock is being delisted, Nasdaq’s rules permit the Company to appeal the delisting determination by the Nasdaq staff (the “Staff”) to a hearings panel.   The Company intends to monitor the bid price of the Company’s listed securities and may, if appropriate, consider available options to regain compliance with the bid price requirement.   There can be no assurance that the Company will be able to regain compliance with the bid price requirement.   Nasdaq Stockholders’ Equity Deficiency Letter   On May 23, 2024, the Company received written notice (the “Equity Notice”) from Nasdaq informing the Company that it no longer complies with the requirement under Nasdaq Listing Rule 5550(b)(1) to maintain a minimum of $2,500,000 in stockholders’ equity for continued listing on Nasdaq because the Company reported stockholders’ equity of negative $6,243,000 in its Quarterly Report on Form 10-Q for the period ended March 31, 2024, and, as of the date of the Equity Notice, the Company did not meet the alternatives of market value of listed securities or net income from continuing operations. The Notice has no immediate effect on the listing or trading of the Company’s securities.   The Company timely submitted the compliance plan to the Staff on July 8, 2024. If the plan is accepted, the Staff may grant the Company an extension period of up to 180 calendar days from the date of the Notice to evidence compliance. There can be no assurance that the Company will be able to regain compliance with the continued listing requirements or that the Staff will grant the Company a further extension of time to regain compliance. If the Staff does not accept the Company’s plan or if the Company is unable to regain compliance within any extension period granted by the Staff, the Company’s common stock will be subject to delisting. In the event the Company receives notice that the Company’s common stock is being delisted, Nasdaq’s rules permit the Company to appeal the delisting determination by the Staff to a hearings panel.

Accounting Policies [Abstract]
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. GAAP and applicable SEC rules. The condensed consolidated financial statements include all accounts of the Company, its majority owned subsidiary KCP, and its wholly owned subsidiary, KVHF. All intercompany transactions and balances have been eliminated upon consolidation. Noncontrolling interest in the accompanying condensed consolidated financial statements represents the proportionate share of equity which is not held by the Company. Net income (loss) of the non-wholly owned consolidated subsidiary is allocated to the Company and the holder(s) of the noncontrolling interests in proportion to their percentage ownership considering any preferences specific to the form of equity of the subsidiaries.
Revenue Recognition	Revenue Recognition Licensing Revenues   In June 2023, the Company achieved a development milestone pursuant to the Merck Neuromuscular License Agreement (defined below), which triggered a $5.0 million payment. This collaboration focused on the discovery and development of novel candidates for the treatment of amyotrophic lateral sclerosis (“ALS”). Merck will continue to advance the research program for the ALS pipeline, one of the two pipeline programs licensed under the Merck Neuromuscular License Agreement. As a result, the Company is eligible to receive up to an additional $255.0 million in development milestones, sales milestones and royalties on net sales. Following this milestone, Merck will assume sole responsibility for all future development and commercialization for the ALS program. The Company recognized licensing revenues of zero for the three and six months ended June 30, 2024.The Company recognized one-time licensing revenue of $5.0 million for the three months ended June 30, 2023.   Collaboration Revenues   In connection with the Merger, the Company became the successor in interest to an exclusive license and research collaboration agreement (the “Merck Neuromuscular License Agreement”) with Merck to support research, development and commercialization of products for treatment of neuromuscular diseases, including amyotrophic lateral sclerosis. The Company recognizes revenue using the cost-to-cost method, which it believes best depicts the transfer of control to the customer. Under the cost-to-cost method, the extent of progress towards completion is measured based on the ratio of actual costs incurred to the total estimated costs expected upon satisfying the identified performance obligation. Under this method, revenue is recognized as a percentage of actual cost incurred to the estimated costs to complete. The Company recognized collaboration revenues of zero for the three and six months ended June 30, 2024. The Company recognized collaboration revenues of $161,000 for the three months ended June 30, 2023 and $442,000 for the six months ended June 30, 2023. As of June 30, 2023, the Company completed its project services under the Merck Neuromuscular License Agreement.
Net income (loss) per share	Net income (loss) per share Basic net income (loss) per common share is computed by dividing the net income (loss) by the weighted average number of shares of common stock outstanding for the period. Diluted net income (loss) per common share is computed by dividing net income (loss) by the weighted average number of common shares outstanding for the period, including potential dilutive common shares assuming the dilutive effect of outstanding common share equivalents. For the three and six months ended June 30, 2024 and the six months ended June 30, 2023, the Company reported a net loss and the diluted net loss per common share is the same as basic net loss per common share, since dilutive common shares are not assumed to have been issued if their effect is anti-dilutive. For the three months ended June 30, 2023, the diluted net income per common share was the same as basic net income per common share, as all potentially dilutive common share equivalents were determined to be anti-dilutive, using the treasury stock method.
