Corporate Updates

• In April 2024, Kintara and TuHURA Biosciences, Inc. ("TuHURA") entered into definitive merger agreement (the "Merger Agreement"), pursuant to which Kayak Mergeco, Inc., Kintara's wholly-owned subsidiary, will merge with and into TuHURA, with TuHURA surviving the merger and becoming Kintara's direct, wholly-owned subsidiary (the "Merger").

• Special Meeting of Stockholders (the "Special Meeting") to obtain stockholder approval of the proposals set forth in Kintara's proxy statement for the Special Meeting required to allow for completion of the proposed Merger with TuHURA will be held virtually on Friday, September 20, 2024, at 9:00 a.m., Eastern Time via live audio webcast.

REM-001 Clinical Study Update

• As of September 10, 2024, the REM-001 study in patients with cutaneous metastatic breast cancer (CMBC) has enrolled four of the 10 patients needed to reach the minimum patient enrollment to assess safety and appropriate Phase 3 dose with several other patients identified as study candidates at Kintara's clinical sites, the Memorial Sloan Kettering Cancer Center and the Montefiore Medical Center, the University Hospital for Albert Einstein College of Medicine.
  
  
• Consistent with REM-001's safety profile, no treatment-related safety issues have been identified to-date, and assessment of the appropriate Phase 3 dose is ongoing.
  
  
• CMBC represents an unmet medical need, as there currently are no approved or effective therapies. REM-001 may potentially offer these patients a much needed treatment option. The majority of the cost associated with the REM-001 study is being covered by a $2.0 million Small Business Innovation Research (SBIR) grant Kintara was awarded previously from the National Institutes of Health.

Without the completion of the proposed Merger with TuHURA, Kintara may not have adequate financial resources to continue the REM-001 study or operate its business and may be required to seek the protection of the bankruptcy courts. Kintara stockholders are urged to vote their shares before the Special Meeting on September 20, 2024.
