EXPLANATORY NOTE

On October18, 2024 (the “Closing Date”), subsequent to the fiscal quarter ended September 30, 2024, the fiscal quarter to which this Quarterly Report on Form 10-Q (this “Report”) relates, the Nevada corporation formerly known as Kintara Therapeutics, Inc. (“Kintara”) consummated a previously announced merger transaction in accordance with the terms of that certain Agreement and Plan of Merger, dated as of April 2, 2024 (the “Merger Agreement”), by and among Kintara, Kayak Mergeco, Inc., a Delaware corporation and direct wholly owned subsidiary of Kintara (“Merger Sub”), and TuHURA Biosciences, Inc., a Delaware corporation (“TuHURA”), pursuant to which, Merger Sub merged with and into TuHURA, with TuHURA surviving as a direct wholly owned subsidiary of Kintara and the surviving corporation of the merger (the “Merger”). In connection with the completion of the Merger, effective at 12:01 a.m. Eastern Time on the Closing Date, Kintara effected a 1-for-35 reverse stock split (the “Reverse Stock Split”) of its common stock, par value $0.001 per share. Effective at 12:03 a.m. Eastern Time on the Closing Date, Kintara completed the merger, and effective at 12:04 a.m. Eastern Time on the Closing Date, Kintara changed its name to “TuHURA Biosciences, Inc.”

Under the terms of the Merger, at the effective time of the Merger, (i) Kintara issued an aggregate of approximately 40,441,605 shares of Common Stock to TuHURA stockholders, based on an exchange ratio of 0.1789 (after giving effect to the Reverse Stock Split) shares of Kintara’s common stock for each share of TuHURA common stock outstanding immediately prior to the Merger, (ii) each then-outstanding TuHURA stock option was assumed and converted into an option to purchase shares of Kintara common stock subject to certain adjustments based on the exchange ratio as set forth in the Merger Agreement, and (iii) each then-outstanding warrant to purchase shares of TuHURA common stock was assumed and converted into and exchangeable based on the exchange ratio for a warrant of like tenor entitling the holder to purchase shares of Kintara common stock.

The issuance of the shares of Kintara’s common stock to the former stockholders of TuHURA was registered with the SEC on the Kintara’s Registration Statement on Form S-4 (File No. 333-279368), as amended.

The shares of Kintara’s common stock listed on the Nasdaq Capital Market, previously trading through the close of business on Thursday, October 17, 2024 under the ticker symbol “KTRA,” commenced trading on the Nasdaq Capital Market on a post-Reverse Stock Split adjusted basis and post-Merger basis under the ticker symbol “HURA” on Friday, October 18, 2024. Kintara’s common stock is represented by a new CUSIP number, 898920 103.

In connection with the Merger, Kintara entered into a Contingent Value Rights Agreement (the “CVR Agreement”) with Equiniti Trust Company, LLC, pursuant to which the Kintara common stock holders and Kintara common stock warrant holders of record as of immediately prior to the consummation of the Merger and Reverse Stock Split received one contingent value right (a “CVR”) for each outstanding share of common stock held by such stockholder (or, in the case of warrants, each share of common stock for which such warrant is exercisable into). Pursuant to the CVR Agreement, upon the achievement of (i) Kintara enrolling a minimum of ten cutaneous metastatic breast cancer patients in a study to determine whether a dose of Kintara’s REM-001 lower than 1.2 mg/kg elicits a treatment effect similar to that seen in prior studies of REM-001 at the 1.2 mg/kg dose and (ii) such patients enrolled in the study complete eight weeks of follow-up, in each case, on or before December 31, 2025, as set forth in the CVR Agreement (the holders of CVRs are entitled, in the aggregate, to receive approximately 1,539,918 shares of common stock (which gives effect to the Reverse Stock Split).

Unless context otherwise requires, the use of “we,” “us,” “our,” and the “Company” in this Report refers to Kintara Therapeutics, Inc., a Nevada corporation pre-Merger and its wholly owned subsidiaries.

Except as otherwise expressly provided herein, the information in this Report does not reflect the consummation of the Merger, which, as discussed above, occurred subsequent to the period covered hereunder.

1 Nature of operations, corporate history, and going concern and management plans

Nature of operations

Kintara Therapeutics, Inc., a Nevada corporation (“Kintara” or, the “Company”) is a clinical-stage drug development company with a focus on the development of novel cancer therapies for patients with unmet medical needs. The Company is developing one late-stage therapeutic - REM-001 for cutaneous metastatic breast cancer (“CMBC”). In order to accelerate the Company’s development timelines, it leverages existing preclinical and clinical data from a wide range of sources. The Company may seek marketing partnerships in order to potentially offset clinical costs and to generate future royalty revenue from approved indications of its current and future product candidates.

Merger with TuHURA Biosciences, Inc.

On April 2, 2024, the Company entered into a definitive Agreement and Plan of Merger with TuHURA Biosciences, Inc., a Delaware corporation (“TuHURA”), and Kayak Mergeco, Inc., a Delaware corporation wholly owned subsidiary the Company (“Merger Sub”), for an all-stock merger transaction (the “Merger”) forming a company with expertise and resources to advance a risk diversified late-stage oncology pipeline (the “Merger Agreement”). The Merger Agreement provided that, upon completion of the Merger, the former TuHURA stockholders would own the majority of the shares of the Company. The Merger and other transactions contemplated by the Merger Agreement closed on October 18, 2024 (see note 10). Unless context otherwise requires, the use of “we,” “us,” “our,” and the “Company” in this Report refers to Kintara Therapeutics, Inc., a Nevada corporation pre-Merger and its wholly owned subsidiaries.

Corporate history

The Company is a Nevada corporation formed on June 24, 2009, under the name Berry Only, Inc. On January 25, 2013, the Company entered into and closed an exchange agreement (the “Exchange Agreement”), with Del Mar Pharmaceuticals (BC) Ltd. (“Del Mar (BC)”), 0959454 B.C. Ltd. (“Callco”), and 0959456 B.C. Ltd. (“Exchangeco”) and the security holders of Del Mar (BC). Upon completion of the Exchange Agreement, Del Mar (BC) became a wholly-owned subsidiary of the Company (the “Reverse Acquisition”).

On August 19, 2020, the Company completed its merger with Adgero Biopharmaceuticals Holdings, Inc., a Delaware corporation (“Adgero”) in which Adgero continued its existence under Delaware law and became a direct, wholly-owned subsidiary of the Company. Following the completion of the merger, the Company changed its name from DelMar Pharmaceuticals, Inc. to Kintara Therapeutics, Inc. and began trading on The Nasdaq Capital Market LLC (“Nasdaq”) under the symbol “KTRA”.

Kintara Therapeutics, Inc. is the parent company of Del Mar (BC), a British Columbia, Canada corporation and Adgero, which are clinical-stage companies with a focus on the development of drugs for the treatment of cancer. The Company is also the parent company to Callco and Exchangeco which are British Columbia, Canada corporations. Callco and Exchangeco were formed to facilitate the Reverse Acquisition. In connection with the Adgero merger, the Company also became the parent company of Adgero Biopharmaceuticals, Inc. (“Adgero Bio”), formerly a wholly-owned subsidiary of Adgero.

On October 18, 2024, the Company completed its merger with TuHURA and Merger Sub pursuant to the terms of the Merger Agreement. In connection with the Merger, Merger Sub merged with and into TuHURA with TuHURA surviving the Merger as a wholly owned subsidiary of the Company. Following the completion of the Merger, the Company changed its corporate name to “TuHURA Biosciences, Inc.”

References to the Company refer to the Company and its wholly-owned subsidiaries.

Going concern and management plans

These condensed consolidated interim financial statements have been prepared on a going concern basis which assumes that the Company will continue its operations for the foreseeable future and contemplates the realization of assets and the settlement of liabilities in the normal course of business.

For the three months ended September 30, 2024, the Company reported a loss of $2,161 and a negative cash flow from operations of $1,889. The Company had an accumulated deficit of $162,052 and had cash and cash equivalents of $3,020 as of

September 30, 2024. The Company is in the clinical stage and has not generated any revenues to date. The Company does not have the prospect of achieving revenues until such time that its product candidate is commercialized, or partnered, which may not ever occur. On August 2, 2022, the Company entered into a stock purchase agreement under which the Company has issued 19 shares of common stock for $2,008 in net proceeds as of September 30, 2024. In addition, on June 28, 2023, the Company announced that it had been awarded approximately $2,000 in grant funding to be received over a two-year period for its REM-001 project. During the year ended June 30, 2024, the Company issued an additional 1,519 shares of common stock for net proceeds of $10,471 from its at-the-market (“ATM”) facility, and announced that it is suspending the development of VAL-083. Even with the proceeds from the grant funding, the stock purchase financing, and the ATM sales, the Company will require additional funding to maintain its clinical trials, research and development projects, and for general operations.

These circumstances indicate substantial doubt exists about the Company’s ability to continue as a going concern within one year from the date of filing of these condensed consolidated interim financial statements.

On October 18, 2024, the Company completed the Merger with TuHURA, on and subject to the terms of the Merger Agreement (Note 11).

Consequently, management is pursuing various financing alternatives to fund the Company’s operations so it can continue as a going concern. Management plans to continue to pursue opportunities to secure the necessary financing through the issue of new equity, including debt, entering into strategic partnership arrangements, and/or pursuing additional strategic transactions. However, the Company’s ability to raise additional capital could be affected by various risks and uncertainties including, but not limited to, global unrest. The Company may not be able to raise sufficient additional capital and may need to tailor its drug candidate development programs based on the amount of funding the Company is able to raise in the future. Nevertheless, there is no assurance that these initiatives will be successful.

These condensed consolidated interim financial statements do not give effect to any adjustments to the amounts and classification of assets and liabilities that may be necessary should the Company be unable to continue as a going concern, that may or may not be material to these condensed consolidated interim financial statements.

2 Significant accounting policies

Reverse stock split

On November 10, 2022, the Company filed a Certificate of Change to the Company’s Articles of Incorporation, as amended, in order to effectuate a 1:50 reverse stock split (the “Reverse Stock Split”) of its issued and outstanding common stock as well as its authorized shares of common stock. As a result of the Reverse Stock Split, every 50 shares of issued and outstanding common stock were converted into one share of common stock with a proportionate reduction in the Company's authorized shares of common stock. Any fractional shares of common stock resulting from the Reverse Stock Split were rounded up to the nearest whole post-Reverse Stock Split share. The Reverse Stock Split did not change the par value of the Company's common stock. All outstanding securities entitling their holders to acquire shares of common stock were adjusted as a result of the Reverse Stock Split. All common share and per share data are retrospectively restated to give effect to the Reverse Stock Split for all periods presented herein.

Basis of presentation

The condensed consolidated interim financial statements of the Company have been prepared in accordance with United States Generally Accepted Accounting Principles (“U.S. GAAP”) and are presented in United States dollars. The functional currency of the Company and each of its subsidiaries is the United States dollar.

The accompanying condensed consolidated interim financial statements include the accounts of the Company and its wholly-owned subsidiaries, Adgero, Adgero Bio, Del Mar (BC), Callco, and Exchangeco. All intercompany balances and transactions have been eliminated in consolidation.

The principal accounting policies applied in the preparation of these condensed consolidated interim financial statements are set out below and have been consistently applied to all periods presented.

Unaudited interim financial data

The accompanying unaudited condensed consolidated interim financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”) for interim financial information. Accordingly, they do not include all of the information and the notes required by U.S. GAAP for complete financial statements. These unaudited condensed consolidated interim financial statements should be read in conjunction with the June 30, 2024, audited consolidated financial statements of the Company included in the Company’s Form 10-K filed with the SEC on October 7, 2024. In the opinion of

management, the unaudited condensed consolidated interim financial statements reflect all adjustments, consisting of normal and recurring adjustments, necessary for a fair presentation. The results for three months ended September 30, 2024, are not necessarily indicative of the results to be expected for the fiscal year ending June 30, 2025, or for any other future annual or interim period.

Use of estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions about future events that affect the reported amounts of assets, liabilities, expenses, contingent assets, and contingent liabilities as at the end of, or during, the reporting period. Actual results could significantly differ from those estimates. Significant areas requiring management to make estimates include the valuation of equity instruments issued for services, milestone payment liability, and clinical trial accruals. Further details of the nature of these assumptions and conditions may be found in the relevant notes to these condensed consolidated interim financial statements.

Loss per share

Loss per share is calculated based on the weighted average number of common shares outstanding. For the three-month periods ended September 30, 2024, and 2023, diluted loss per share does not differ from basic loss per share since the effect of the Company’s warrants, stock options, restricted stock units, and convertible preferred shares is anti-dilutive. As of September 30, 2024, potential common shares of 17 (2023 – 20) related to outstanding common share warrants, nil (2023 – 1) related to outstanding Series C preferred stock warrants, 6 (2023 – 8) related to stock options, nil (2023 - 2) related to restricted stock units, and nil (2023 – 7) relating to outstanding Series C convertible preferred shares were excluded from the calculation of net loss per common share.

Government assistance

Government grants, including grants from similar bodies, are recognized when there is reasonable assurance that the Company has met the requirements of the approved grant program and there is reasonable assurance that the grant will be received. Grants that compensate the Company for expenses incurred are recognized in income or loss in reduction thereof in the same period in which the expenses are recognized. The Company uses a net presentation basis whereby the grant offsets the research and development expenses as it is being recovered under the grant program.

Recently issued accounting standards

Management does not believe that any recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the Company’s condensed consolidated interim financial statements.

3 Clinical trial deposit

In October 2020, the Company announced that it had entered into a final agreement with a contract research organization (“CRO”) for the management of the Company’s registrational study of VAL-083 for glioblastoma. Under the agreement, the Company supplied the drug for the study and the CRO managed all operational aspects of the study including site activation and patient enrollment. The Company was required to make certain payments under the agreement related to patient enrollment milestones. For the three months ended September 30, 2024, the Company has recognized an expense of $nil (2023 - $1,075) for this study in relation to clinical site initiation and patient enrollment.

On October 31, 2023, the Company announced that preliminary topline results from this registrational study for VAL-083 did not perform better than the current standards of care in glioblastoma. As a result, the Company announced that it has terminated the development of VAL-083. In the year ended June 30, 2024, the remaining deposit of $1,075 was offset against amounts owing to the CRO and the agreement with the CRO was terminated with an additional final cost of $1,000, which was paid in the year ended June 30, 2024.

As of June 30, 2024, and September 30, 2024, the Company has recorded $205 as a deposit with a CRO for the management of the Company’s 15-patient study of REM-001 for cutaneous metastatic breast cancer (“CMBC”).

4 Clinical trials grant

Effective July 1, 2023, the Company was awarded a $2,000 Small Business Innovation Research grant from the National Institutes of Health (“NIH”) to support the clinical development of REM-001 for the treatment of CMBC. The grant will be received in two tranches: approximately $1,250 for the period July 1, 2023, to June 30, 2024, and approximately $750 for the period July 1, 2024, to June 30, 2025. As a result of receiving the grant, the REM-001, 15-patient clinical trial was restarted. The grant is expended

to the Company as a reimbursement of expenditures incurred. During the three months ended September 30, 2024, the Company received $236 (2023 - $13) for grants received against research and development expenditures in the period.

The grant is subject to various performance conditions and funding risk where the financial conditions of the NIH may change from time to time. The Company recognizes the grant only to the extent there is reasonable assurance the grant will be funded to the Company.

In August 2020, the Company issued 25,028 shares of Series C Convertible Preferred Stock (the “Series C Preferred Stock”) in three separate closings of a private placement (Series C-1, C-2, and C-3). Each share of Series C Preferred Stock was issued at a purchase price of $1,000 per share and is convertible into shares of common stock based on the respective conversion prices which were determined at the closing of each round of the private placement. The conversion prices for the Series C-1 Preferred Stock, Series C-2 Preferred Stock, and the Series C-3 Preferred Stock were $2,030.00, $2,124.50, and $2,012.50, respectively. Subject to ownership limitations, the owners of the Series C-1 Preferred Stock, the Series C-2 Preferred Stock, and the Series C-3 Preferred Stock were entitled to receive dividends, payable in shares of common stock at a rate of 10%, 15%, 20% and 25%, respectively, of the number of shares of common stock issuable upon conversion of the Series C Preferred Stock, on the 12th, 24th, 36th and 48th month, anniversary of the initial closing of the private placement.

The Series C Preferred Stock dividends did not require declaration by the board of directors and were accrued annually as of the date the dividend was earned in an amount equal to the fair value of the Company’s common stock on the dates the respective dividends were paid. The fair value of the Series C Preferred Stock dividend paid on August 19, 2024, was determined by multiplying the dividends paid of 2 shares of common stock by the Company’s closing share price on August 18, 2024, of $7.93 per share for a total fair value of $13. All outstanding shares of Series C Preferred Stock were automatically converted to an aggregate of 7 shares of common stock on August 19, 2024. In addition, as part of the Series C Preferred financing, the Company issued warrants to the placement agent (“Series C Agent Warrants”), which expired unexercised on August 19, 2024.

The Series C Preferred Stock was pari passu in liquidation to the Company’s Series A Preferred Stock. The liquidation value of the Series C Preferred Stock at September 30, 2024, is the stated value of $nil (June 30, 2024 - $9,973).

10 Financial instruments

The Company's financial instruments are measured at fair value as determined by using the fair value hierarchy for inputs that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs market participants would use to value an asset or liability and are developed based on market data obtained from independent sources. Unobservable inputs are inputs based on assumptions about the factors market participants would use to value an asset or liability. The three levels of inputs that may be used to measure fair value are as follows:

 Level one - inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities;

 Level two - inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly such as interest rates, foreign exchange rates, and yield curves that are observable at commonly quoted intervals; and

 Level three - unobservable inputs developed using estimates and assumptions, which are developed by the reporting entity and reflect those assumptions that a market participant would use.

Assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurements. Changes in the observability of valuation inputs may result in a reclassification of levels for certain securities within the fair value hierarchy. As of September 30, 2024, the Company’s milestone payment liability was measured using level three inputs. The milestone payment liability relates to contingent milestone payments for the REM-001 program that was acquired in the Adgero merger (note 1).

The Company’s financial instruments consist of cash and cash equivalents, other receivables, accounts payable, and related party payables. The carrying values of cash and cash equivalents, other receivables, accounts payable and related party payables approximate their fair values due to the immediate or short-term maturity of these financial instruments.

Merger with TuHURA Biosciences, Inc.

On October 4, 2024, at the Company’s Special Meeting of Stockholders, the Company’s stockholders approved the requisite proposals to effect the completion of the Merger pursuant to the Merger Agreement, whereby Merger Sub merged with and into TuHURA, with TuHURA surviving the Merger and becoming direct, wholly owned subsidiary of the Company. Effective at 12:01 a.m. Eastern Time on October 18, 2024, the Company effected the Reverse Stock Split, whereby every 35 shares of issued and outstanding common stock were converted into one share of common stock. Any fractional shares of common stock resulting from the Reverse Stock Split were rounded up to the nearest whole post-Reverse Stock Split share. The Reverse Stock Split did not change the par value of the Company’s common stock or the amount of authorized common stock. Effective at 12:03 a.m. Eastern Time on

October 18, 2024, the Company completed the Merger, and effective at 12:04 a.m. Eastern Time on October 18, 2024, the Company changed its name to “TuHURA Biosciences, Inc.”

Subject to the terms and conditions of the Merger Agreement, at the effective time of the Merger (the “Effective Time”), (i) each then-outstanding share of TuHURA common stock, par value $0.001 per share (the “TuHURA Common Stock”) (other than any shares held in treasury and Dissenting Shares (as defined in the Merger Agreement)) were converted into shares of the Company’s common stock equal to an exchange ratio of 0.1789 (after giving effect to the Reverse Stock Split), (ii) each then-outstanding TuHURA stock option were assumed and converted into an option to purchase shares of the Company’s common stock, subject to certain adjustments as set forth in the Merger Agreement, and (iii) each then-outstanding warrant to purchase shares of TuHURA Common Stock”) was assumed and converted into and exchangeable for a warrant of like tenor entitling the holder to purchase shares of the Company’s common stock, subject to certain adjustments as set forth in the Merger Agreement. Existing Company stockholders received one CVR for each share of common stock held by such stockholder (or, in the case of warrants, each share of common stock of the Company for which such warrant is exercisable into), entitling them to receive, in the aggregate, approximately 1,539,918 shares of the Company's common stock (collectively, the “CVR Shares”) upon achievement of enrollment of a minimum of 10 patients in the REM-001 clinical trial, with such patients each completing 8 weeks of follow-up on or before December 31, 2025 (the “Milestone”).

Immediately following the Merger, TuHURA stockholders as of immediately prior to the Merger owned, in aggregate and on a fully-diluted basis, approximately 97.15% of the Company (or 94.55% of the Company after giving effect to the issuance of the CVR Shares assuming the Milestone has been achieved) and Company securityholders as of immediately prior to the Merger owned, in aggregate and on a fully-diluted basis, approximately 2.85% of the Company (or 5.45% of the Company after giving effect to the issuance of the CVR Shares assuming the Milestone has been achieved).

On October 18, 2024, effective immediately prior to the consummation of the Merger, the Company completed a 1-for-35 reverse stock split (the “2024 Reverse Stock Split”) of its issued and outstanding common stock in connection with the Merger Agreement with TuHURA. As a result of the 2024 Reverse Stock Split, every 35 shares of issued and outstanding common stock were converted into one share of common stock. Any fractional shares of common stock resulting from the 2024 Reverse Stock Split were rounded up to the nearest whole post-2024 Reverse Stock Split share. The 2024 Reverse Stock Split did not change the par value of the Company's common stock or the amount of authorized common stock. All outstanding securities entitling their holders to acquire shares of common stock were adjusted as a result of the 2024 Reverse Stock Split. All common share and per share data are retrospectively restated to give effect to the 2024 Reverse Stock Split for all periods presented herein.

REM-001

Background

Through REM-001, we are developing our photodynamic therapy (“PDT”) for the treatment of rare, unmet medical needs. PDT is a treatment that uses light sensitive compounds, or photosensitizers, that, when exposed to specific wavelengths of light, act as catalysts to produce a form of oxygen that induces local tumor cell death. REM-001 consists of three parts: the laser light source, the light delivery device, and the REM-001 drug product (collectively, the “REM-001 Therapy”). REM-001 consists of an active pharmaceutical ingredient (“API”) in a lipid formulation. The REM-001 API is SnET2 (“tin ethyl etiopurpurin”) which is a second-generation PDT photosensitizer agent. We believe REM-001 possesses multiple advantages over earlier generation PDT compounds.

Our lead indication for REM-001 is CMBC which is a disease that may strike individuals with advanced breast cancer and for which effective treatment options are limited. In four Phase 2 and/or Phase 3 clinical studies in CMBC patients, primarily targeting patients who had previously received chemotherapy and failed radiation therapy, REM-001 Therapy was able to reduce, or eliminate, a substantial number of the treated CMBC tumors. Specifically, our analysis of the data collected from these studies indicates that in approximately 80% of evaluable tumor sites treated with REM-001 Therapy, there was a complete response; meaning that follow-up clinical assessments indicated no visible evidence of the tumor remaining. We believe clinical data indicates that REM-001 Therapy holds promise as a treatment to locally eliminate, or slow the growth of, treated cutaneous cancerous tumors in this difficult-to-treat patient population.

Numerous approaches have been utilized to treat CMBC patients, including various forms of chemotherapy, radiation therapy, surgical excision, hyperthermia, cryotherapy, electro-chemotherapy, topical drugs, and intra-lesional chemotherapy injections. However, for the most part, we believe that these therapies are often inadequate given the limited efficacy, toxicities and/or side effects of each. We believe our REM-001 Therapy has several advantages for this indication: it can be highly directed to the tumor site, has minimal systemic effects or normal tissue toxicities, can be used in conjunction with other therapies, and can be periodically repeated.

Our REM-001 Therapy product consists of three parts: the DD series laser light source (or equivalent), the ML2-0400 light delivery device (or equivalent) and the drug REM-001. In use, REM-001 is first administered by intravenous infusion and allowed to distribute within the body and be taken up by the tumors. Tumors are then illuminated with light using the light delivery device, which is attached to the laser light source, so that the accumulated REM-001 can be activated for the desired clinical effect.

As a result of our review of the historical data, we submitted questions to the U.S. Food and Drug Administration (“FDA”) under a Type C format to review the technology and results and determine the anticipated requirements for regulatory approval. On March 3, 2017, we received the FDA’s written response to these questions. Based on that response, we have successfully

manufactured REM-001 and developed light delivery devices for our planned 15-patient Phase 2 study. We received a Study May Proceed letter from the FDA for our 15-patient study on August 9, 2022.

On October 19, 2022, we announced that the REM-001 program in CMBC was paused to conserve cash which will be used to support the funding of the GBM AGILE Study. Effective July 1, 2023, we were awarded a two-year $2,000 Small Business Innovation Research grant from the National Institutes of Health to support the clinical development of REM-001 for the treatment of CMBC. The grant will be received in tranches of approximately $1,250 for the period July 1, 2023, to June 30, 2024, and approximately $750 for the period July 1, 2024, to June 30, 2025. As a result of receiving the grant, we re-initiated our REM-001 program and have opened enrollment at Memorial Sloan Kettering Cancer Center, where we have initiated treatment in a total of 4 patients as of November 14, 2024. We expect to complete enrollment of patients in the REM-001 Study in the fourth calendar quarter of 2024.

REM-001 Regulatory Filings

On August 9, 2022, we announced that we received a Study May Proceed letter from the FDA to begin our 15-patient study evaluating REM-001 PDT for the treatment of CMBC. The FDA has granted us Fast Track Designation (“FTD”) for REM-001 in CMBC.

VAL-083

On October 31, 2023, we announced preliminary topline results for VAL-083 from the GBM AGILE study. VAL-083 did not perform better than the current standards of care in glioblastoma and the preliminary safety data was similar to that of the current standards of care used to treat glioblastoma. As a result, we terminated the development of VAL-083. On February 13, 2024, we sent an Opt-Out Notice to Valent under the Valent Assignment Agreement whereby we assigned all rights, title, and interest in and to the patents for VAL-083 to Valent. As a result, we granted Valent a non-exclusive, fully-paid, royalty-free, perpetual, worldwide and non-transferable license, subject to limited exceptions. We are entitled to receive royalties from Valent’s subsequent commercialization of VAL-083 equal to 5% of Valent Net Sales (as defined in the Valent Assignment Agreement).

Research and Development

Research and development expenses decreased to $252 for the three months ended September 30, 2024, from $1,859 for the three months ended September 30, 2023. The decrease was largely attributable to lower clinical development costs and related decreases in personnel and patent costs incurred during the three months ended September 30, 2024, compared to the three months ended September 30, 2023, primarily due to termination of the development of VAL-083 in October of 2023. Non-cash, share-based compensation expense decreased to $38 for the three months ended September 30, 2024, from $86 for the three months ended September 30, 2023, due to the recognition of higher compensation expense recognized during the three months ended September 30, 2023, for stock options granted in August 2023.

General and Administrative

General and administrative expenses were $1,957 for the three months ended September 30, 2024, compared to $1,103 for the three months ended September 30, 2023. A significant portion of the increase was a result of higher professional fees and special meeting fees incurred in relation to the transaction with TuHURA, offset by lower non-cash, share-based compensation expenses and a reduction in travel costs in the current three months compared to the same period in the prior fiscal year. Non-cash, share-based compensation expense decreased to $63 for the three months ended September 30, 2024, from $121 for the three months ended September 30, 2023, due to the recognition of higher compensation expense recognized during the three months ended September 30, 2023, for stock options granted in August 2023. Personnel, facilities, office and sundry costs have increased primarily due to special meeting costs, filing fees, and shareholder communication costs related to the transaction with TuHURA.

Preferred Share Dividends

For each of the three months ended September 30, 2024, and 2023, we recorded $2 related to the cash dividend payable to Valent on the Series A Preferred Stock. The dividend has been recorded as a direct increase in accumulated deficit for both periods. In addition, for the three months ended September 30, 2024, we recorded $13 (2023 - $173) related to the stock dividend payable to investors on the Series C Preferred Stock. The dividends have been recorded as a direct increase in accumulated deficit for both periods.

Operating Activities

Net cash used in operating activities was $1,889 for the three months ended September 30, 2024, compared to $1,317 for the three months ended September 30, 2023. During the three months ended September 30, 2024, and 2023, we reported net losses of $2,161 and $2,962, respectively. Adjustments to reconcile net loss to net cash used in operating activities for the three months ended September 30, 2024, included stock option expense of $98 and restricted stock unit expense of $3 being recognized during the current period compared to $160 and $47, respectively, in the same period in the prior fiscal year.

The most significant change in working capital for the three months ended September 30, 2024, was related to a decrease in prepaid expenses, taxes and other receivables of $156. The most significant changes in working capital for the three months ended September 30, 2023, were related to the use of clinical trial deposit to settle clinical trial expenses of $1,075 and settlement of accounts payable and accrued liabilities of $214.

Investing Activities

There was no investing activity during the three months ended September 30, 2024 and 2023.

Financing Activities

Net cash used in financing activities was $nil for the three months ended September 30, 2024, compared to $2 for the three months ended September 30, 2023 for the payment of the quarterly Series A Preferred Share dividend, which was in accounts payable and accrued liabilities at September 30, 2024.

Going Concern and Capital Expenditure Requirements

Going Concern and Management Plans

(See note 1 to the condensed consolidated interim financial statements)

The condensed consolidated financial statements have been prepared on a going concern basis, which assumes that we will continue our operations for the foreseeable future and contemplates the realization of assets and the settlement of liabilities in the normal course of business.

For the three months ended September 30, 2024, we reported a loss of $2,161 and a negative cash flow from operations of $1,889. We had an accumulated deficit of $162,052 and had cash and cash equivalents of $3,020 as of September 30, 2024. We are in the clinical stage and have not generated any revenues to date. We do not have the prospect of achieving revenues until such time that our product candidate is commercialized, or partnered, which may not ever occur. On August 2, 2022, we entered into the Purchase Agreement under which we received approximately $2,008 in net proceeds as of September 30, 2024, for the issuance of an aggregate of 19 shares of common stock under the Purchase Agreement. On October 9, 2023, we received stockholder approval to issue 20% or more of our outstanding shares as of the date we entered into the Purchase Agreement with Lincoln Park. On February 22, 2024, we determined that we have concluded utilization of the equity facility pursuant to the terms of the Purchase Agreement. In addition, on June 28, 2023, we announced that we had been awarded approximately $2,000 in grant funding for our REM-001 project.

On September 19, 2023, we entered into a Sales Agreement, (the “Sales Agreement”) with AGP pursuant to which we may offer and sell, from time to time, through AGP, as sales agent and/or principal, shares of common stock having an aggregate offering price of up to $10,900 (the “ATM Facility”). From October 31, 2023, until September 30, 2024, we raised $10,471 in net proceeds from the sale of 1,519 shares of our common stock under the ATM Facility. On February 22, 2024, we determined that we have concluded utilization of the ATM facility.

Even with the proceeds from the grant funding, the stock purchase financing, and the ATM sales, we will require significant additional funding to maintain our clinical trials, research and development projects, and for general operations. These circumstances

indicate substantial doubt exists about our ability to continue as a going concern within one year from the date of filing of these condensed consolidated financial statements.

Consequently, management began pursuing various financing alternatives to fund our operations in the short and long term and so we can continue as a going concern. In addition, we initiated a process to explore and review a range of strategic alternatives focused on maximizing shareholder value, and as a result, entered into the Merger Agreement for the Merger with TuHURA, which closed on October 18, 2024. Our ability to raise additional capital is unknown and will depend on future developments, which are highly uncertain and cannot be predicted with confidence. We may not be able to raise sufficient additional capital and may tailor our drug candidate development program based on the amount of funding we are able to raise in the future. Nevertheless, there is no assurance that these initiatives will be successful.

The condensed consolidated financial statements do not give effect to any adjustments to the amounts and classification of assets and liabilities that may be necessary should we be unable to continue as a going concern. Such adjustments could be material.

Our future funding requirements will depend on many factors, including but not limited to:

•

the rate of progress and cost of our clinical studies, preclinical studies and other discovery and research and development activities;

•

the costs associated with establishing manufacturing and commercialization capabilities;

•

the costs of acquiring or investing in businesses, product candidates and technologies;

•

the costs of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights;

•

the costs and timing of seeking and obtaining FDA and other regulatory approvals;

•

the effect of competing technological and market developments;

•

the economic and other terms and timing of any collaboration, licensing or other arrangements into which we may enter; and

•

the impact of us being a public entity.

Until we can generate a sufficient amount of product revenue to finance our cash requirements, which we may never do, we expect to finance future cash needs primarily through public or private equity offerings, or strategic collaborations. The sale of equity and convertible debt securities may result in dilution to our stockholders and certain of those securities may have rights senior to those of our shares of capital stock. If we raise additional funds through the issuance of preferred stock, convertible debt securities or other debt financing, these securities or other debt could contain covenants that would restrict our operations. Any other third-party funding arrangement could require us to relinquish valuable rights. Economic conditions may affect the availability of funds and activity in equity markets. We do not know whether additional funding will be available on acceptable terms, or at all. If we are not able to secure additional funding when needed, we may have to delay, reduce the scope of or eliminate one or more of our clinical trials or research and development programs or make changes to our operating plan, file for bankruptcy protection or pursue a dissolution of the Company and liquidation of all of our remaining assets. In such an event, the amount of cash available for distribution to our shareholders, if any, will depend heavily on the timing of such decision, as with the passage of time the amount of cash available for distribution will be reduced as we continue to fund our operations. We cannot provide assurance as to the amount of cash that will be available to distribute to shareholders, if any, after paying our debts and other obligations and setting aside funds for reserves, nor as to the timing of any such distribution, if any.

Critical Accounting Policies and Estimates

The preparation of financial statements, in conformity with generally accepted accounting principles in the United States, requires companies to establish accounting policies and to make estimates that affect both the amount and timing of the recording of assets, liabilities, revenues and expenses. Some of these estimates require judgments about matters that are inherently uncertain and therefore actual results may differ from those estimates.

A detailed presentation of all of our significant accounting policies and the estimates derived therefrom is included in Note 2 to our consolidated financial statements for the year ended June 30, 2024, contained in our Annual Report on Form 10-K filed with the SEC on October 7, 2024. While all of the significant accounting policies are important to our consolidated financial statements, the following accounting policies and the estimates derived therefrom are critical:

 Fair value of financial instruments

 Accruals for research and development expenses and clinical trials

Fair value of financial instruments

We recognize compensation costs resulting from the issuance of stock-based awards to employees, non-employees and directors as an expense in the statement of operations over the service period based on a measurement of fair value for each stock-based award. Prior to our adoption of Accounting Standards Update 2018-07, Compensation-Stock Compensation (Topic 718), Improvements to Nonemployee Share-Based Payment Accounting (“ASU 2018-07”), stock options granted to non-employee consultants were revalued at the end of each reporting period until vested using the Black-Scholes option-pricing model and the changes in their fair value were recorded as adjustments to expense over the related vesting period. For the three months ended September 30, 2024, and 2023, the determination of grant-date fair value for stock option awards was estimated using the Black-Scholes model which includes variables such as the expected volatility of our share price, the anticipated exercise behavior of its grantee, interest rates, and dividend yields. For the three months ended September 30, 2024, and 2023, we utilized the plain vanilla method to determine the expected life of stock options. These variables are projected based on our historical data, experience, and other factors. Changes in any of these variables could result in material adjustments to the expense recognized for share-based payments. Such value is recognized as expense over the requisite service period, net of actual forfeitures, using the accelerated attribution method. We recognize forfeitures as they occur. The estimation of stock awards that will ultimately vest requires judgment, and to the extent actual results, or updated estimates, differ from current estimates, such amounts are recorded as a cumulative adjustment in the period estimates are revised.

For the three months ended September 30, 2024, and 2023, we issued stock options to our officers. The determination of grant-date fair value for options granted was estimated using the Black-Scholes model which includes variables such as the expected volatility of our share price, interest rates, dividend yields, and the term of the option.

Accruals for research and development expenses and clinical trials

As part of the process of preparing our financial statements, we are required to estimate our expenses resulting from our obligations under contracts with vendors, clinical research organizations and consultants, and under clinical site agreements in connection with conducting clinical trials. The financial terms of these contracts are subject to negotiations, which vary from contract to contract and may result in payment terms that do not match the periods over which materials or services are provided under such contracts. Our objective is to reflect the appropriate expenses in our financial statements by matching those expenses with the period in which services are performed and efforts are expended. We account for these expenses according to the timing of various aspects of the expenses. We determine accrual estimates by taking into account discussion with applicable personnel and outside service providers as to the progress of clinical trials, or the services completed. During the course of a clinical trial, we adjust our clinical expense recognition if actual results differ from our estimates. We make estimates of our accrued expenses as of each balance sheet date based on the facts and circumstances known to us at that time. Our clinical trial accruals are dependent upon the timely and accurate reporting of contract research organizations and other third-party vendors. Although we do not expect our estimates to be materially different from amounts actually incurred, our understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and may result in us reporting amounts that are too high or too low for any particular period. For the three months ended September 30, 2024, and 2023, there were no material adjustments to our prior period estimates of accrued expenses for clinical trials.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

In designing and evaluating our disclosure controls and procedures, our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and our management necessarily is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

(b) Changes in Internal Controls. There were no changes in our internal control over financial reporting, identified in connection with the evaluation of such internal control that occurred during the quarter ended September 30, 2024, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Accounting Policies [Abstract]
Significant accounting policies	2 Significant accounting policies Reverse stock split On November 10, 2022, the Company filed a Certificate of Change to the Company’s Articles of Incorporation, as amended, in order to effectuate a 1:50 reverse stock split (the “Reverse Stock Split”) of its issued and outstanding common stock as well as its authorized shares of common stock. As a result of the Reverse Stock Split, every 50 shares of issued and outstanding common stock were converted into one share of common stock with a proportionate reduction in the Company's authorized shares of common stock. Any fractional shares of common stock resulting from the Reverse Stock Split were rounded up to the nearest whole post-Reverse Stock Split share. The Reverse Stock Split did not change the par value of the Company's common stock. All outstanding securities entitling their holders to acquire shares of common stock were adjusted as a result of the Reverse Stock Split. All common share and per share data are retrospectively restated to give effect to the Reverse Stock Split for all periods presented herein. Basis of presentation The condensed consolidated interim financial statements of the Company have been prepared in accordance with United States Generally Accepted Accounting Principles (“U.S. GAAP”) and are presented in United States dollars. The functional currency of the Company and each of its subsidiaries is the United States dollar. The accompanying condensed consolidated interim financial statements include the accounts of the Company and its wholly-owned subsidiaries, Adgero, Adgero Bio, Del Mar (BC), Callco, and Exchangeco. All intercompany balances and transactions have been eliminated in consolidation. The principal accounting policies applied in the preparation of these condensed consolidated interim financial statements are set out below and have been consistently applied to all periods presented. Unaudited interim financial data The accompanying unaudited condensed consolidated interim financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”) for interim financial information. Accordingly, they do not include all of the information and the notes required by U.S. GAAP for complete financial statements. These unaudited condensed consolidated interim financial statements should be read in conjunction with the June 30, 2024, audited consolidated financial statements of the Company included in the Company’s Form 10-K filed with the SEC on October 7, 2024. In the opinion of management, the unaudited condensed consolidated interim financial statements reflect all adjustments, consisting of normal and recurring adjustments, necessary for a fair presentation. The results for three months ended September 30, 2024, are not necessarily indicative of the results to be expected for the fiscal year ending June 30, 2025, or for any other future annual or interim period. Use of estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions about future events that affect the reported amounts of assets, liabilities, expenses, contingent assets, and contingent liabilities as at the end of, or during, the reporting period. Actual results could significantly differ from those estimates. Significant areas requiring management to make estimates include the valuation of equity instruments issued for services, milestone payment liability, and clinical trial accruals. Further details of the nature of these assumptions and conditions may be found in the relevant notes to these condensed consolidated interim financial statements. Loss per share Loss per share is calculated based on the weighted average number of common shares outstanding. For the three-month periods ended September 30, 2024, and 2023, diluted loss per share does not differ from basic loss per share since the effect of the Company’s warrants, stock options, restricted stock units, and convertible preferred shares is anti-dilutive. As of September 30, 2024, potential common shares of 17 (2023 – 20) related to outstanding common share warrants, nil (2023 – 1) related to outstanding Series C preferred stock warrants, 6 (2023 – 8) related to stock options, nil (2023 - 2) related to restricted stock units, and nil (2023 – 7) relating to outstanding Series C convertible preferred shares were excluded from the calculation of net loss per common share. Government assistance Government grants, including grants from similar bodies, are recognized when there is reasonable assurance that the Company has met the requirements of the approved grant program and there is reasonable assurance that the grant will be received. Grants that compensate the Company for expenses incurred are recognized in income or loss in reduction thereof in the same period in which the expenses are recognized. The Company uses a net presentation basis whereby the grant offsets the research and development expenses as it is being recovered under the grant program. Recently issued accounting standards Management does not believe that any recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the Company’s condensed consolidated interim financial statements.

Accounting Policies [Abstract]
Reverse Stock Split	Reverse stock split On November 10, 2022, the Company filed a Certificate of Change to the Company’s Articles of Incorporation, as amended, in order to effectuate a 1:50 reverse stock split (the “Reverse Stock Split”) of its issued and outstanding common stock as well as its authorized shares of common stock. As a result of the Reverse Stock Split, every 50 shares of issued and outstanding common stock were converted into one share of common stock with a proportionate reduction in the Company's authorized shares of common stock. Any fractional shares of common stock resulting from the Reverse Stock Split were rounded up to the nearest whole post-Reverse Stock Split share. The Reverse Stock Split did not change the par value of the Company's common stock. All outstanding securities entitling their holders to acquire shares of common stock were adjusted as a result of the Reverse Stock Split. All common share and per share data are retrospectively restated to give effect to the Reverse Stock Split for all periods presented herein.
Basis of Presentation	Basis of presentation The condensed consolidated interim financial statements of the Company have been prepared in accordance with United States Generally Accepted Accounting Principles (“U.S. GAAP”) and are presented in United States dollars. The functional currency of the Company and each of its subsidiaries is the United States dollar. The accompanying condensed consolidated interim financial statements include the accounts of the Company and its wholly-owned subsidiaries, Adgero, Adgero Bio, Del Mar (BC), Callco, and Exchangeco. All intercompany balances and transactions have been eliminated in consolidation. The principal accounting policies applied in the preparation of these condensed consolidated interim financial statements are set out below and have been consistently applied to all periods presented.
Unaudited Interim Financial Data	Unaudited interim financial data The accompanying unaudited condensed consolidated interim financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”) for interim financial information. Accordingly, they do not include all of the information and the notes required by U.S. GAAP for complete financial statements. These unaudited condensed consolidated interim financial statements should be read in conjunction with the June 30, 2024, audited consolidated financial statements of the Company included in the Company’s Form 10-K filed with the SEC on October 7, 2024. In the opinion of management, the unaudited condensed consolidated interim financial statements reflect all adjustments, consisting of normal and recurring adjustments, necessary for a fair presentation. The results for three months ended September 30, 2024, are not necessarily indicative of the results to be expected for the fiscal year ending June 30, 2025, or for any other future annual or interim period.
Use of Estimates	Use of estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions about future events that affect the reported amounts of assets, liabilities, expenses, contingent assets, and contingent liabilities as at the end of, or during, the reporting period. Actual results could significantly differ from those estimates. Significant areas requiring management to make estimates include the valuation of equity instruments issued for services, milestone payment liability, and clinical trial accruals. Further details of the nature of these assumptions and conditions may be found in the relevant notes to these condensed consolidated interim financial statements.
Loss Per Share	Loss per share Loss per share is calculated based on the weighted average number of common shares outstanding. For the three-month periods ended September 30, 2024, and 2023, diluted loss per share does not differ from basic loss per share since the effect of the Company’s warrants, stock options, restricted stock units, and convertible preferred shares is anti-dilutive. As of September 30, 2024, potential common shares of 17 (2023 – 20) related to outstanding common share warrants, nil (2023 – 1) related to outstanding Series C preferred stock warrants, 6 (2023 – 8) related to stock options, nil (2023 - 2) related to restricted stock units, and nil (2023 – 7) relating to outstanding Series C convertible preferred shares were excluded from the calculation of net loss per common share.
Government Assistance	Government assistance Government grants, including grants from similar bodies, are recognized when there is reasonable assurance that the Company has met the requirements of the approved grant program and there is reasonable assurance that the grant will be received. Grants that compensate the Company for expenses incurred are recognized in income or loss in reduction thereof in the same period in which the expenses are recognized. The Company uses a net presentation basis whereby the grant offsets the research and development expenses as it is being recovered under the grant program.
Recently Issued Accounting Standards	Recently issued accounting standards Management does not believe that any recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the Company’s condensed consolidated interim financial statements.
