"TuHURA had a strong first-half of the year with the initiation of its Phase 3 accelerated approval trial of IFx-2.0 as an adjunctive therapy to pembrolizumab as a first line treatment for patients with advanced or metastatic MCC. Conducted under an SPA Agreement with the FDA, the Phase 3 trial is a single randomized placebo-controlled trial that, if successful, has the potential to both meet and satisfy the requirements for both accelerated and full approval without the need to conduct a post-accelerated approval confirmatory trial. This potentially translates to a meaningful time and cost savings to TuHURA," stated James Bianco, M.D., President and Chief Executive Officer of TuHURA. "In addition to our accelerated approval Phase 3 trial of IFx-2.0, we also initiated a Phase 1b/2a trial employing interventional radiologic administration of IFx-2.0 as an adjunctive therapy to pembrolizumab in first-line treatment of checkpoint-naïve patients with MCC of unknown primary origin (MCCUP). This trial will enroll newly diagnosed patients who present metastatic, deep-seated tumors in the liver, lungs, or retroperitoneum, without accessible cutaneous, subdermal or nodal lesions. Patients with MCCUP represent approximately a thirty percent (30%) of all newly diagnosed advanced or metastatic MCC cases and can meaningfully augment IFx-2.0’s commercial market opportunity."

Dr. Bianco continued, "In addition to our trial initiations in MCC and MCCUP, we recently bolstered our development pipeline with the acquisition of Kineta and their novel VISTA inhibiting antibody, TBS-2025. The acquisition provides for synergies across both TuHURA’s therapeutic focus as well as TuHURA’s antibody peptide or drug candidate (APC, ADC) technologies as we continue to assemble a diversified, late-stage immuno-oncology pipeline. We plan to advance TBS-2025 into a randomized Phase 2 trial in patients with relapsed or refractory NPM1-mutated AML planned for the second half of this year to determine if the addition of TBS-2025 to a menin inhibitor can improve the results seen in patients receiving a menin inhibitor."

Corporate Highlights

Inclusion of TuHURA Biosciences in the Russell 3000 and Russell 2000 Indexes. In June 2025, TuHURA announced its addition to the Russell 3000 Index, with automatic inclusion in the Russell 2000 Index, as a part of the 2025 Russell annual reconstitution. The Company’s addition was effective as of market close on June 27, 2025.
Completion of Kineta, Inc. Acquisition and Kineta’s VISTA Inhibiting mAb. In June 2025, TuHURA announced the closing of its acquisition of Kineta, and Kineta’s novel VISTA inhibiting mAb, now referred to as "TBS-2025." TuHURA plans to initiate a Phase 2 randomized trial of TBS-2025 in combination with a menin inhibitor for the treatment of relapsed or refractory NPM1-mutated AML, compared to a menin inhibitor alone, targeted for the second half of 2025.
Initiation of Phase 3 Accelerated Approval Trial of IFx-2.0 as Adjunctive Therapy to Keytruda in 1L MCC. In June 2025, TuHURA announced that it had initiated its Phase 3 accelerated approval trial of IFx-2.0 as an adjunctive therapy to pembrolizumab in MCC. Conducted under an SPA agreement with the U.S. FDA, TuHURA is investigating the effectiveness of IFx-2.0 as an adjunctive therapy to Keytruda compared to Keytruda plus placebo in first line treatment in advanced or metastatic MCC.
Completed $12.5 Million Equity Financing Transaction and Received an Additional $3.0 Million in Warrant Exercise Proceeds. In June 2025, TuHURA announced that it had entered into a definitive securities purchase agreement for the issuance and sale in a private placement of an aggregate of $12.5 million shares of its common stock.
