TuHURA Biosciences Reports Fourth Quarter and Full Year 2025 Financial Results and Provides a Corporate Update

TAMPA, Fla., April 1, 2026 /PRNewswire/ -- TuHURA Biosciences, Inc. (NASDAQ:HURA) ("TuHURA" or the "Company"), a Phase 3 immuno-oncology company developing novel therapeutics to overcome resistance to cancer immunotherapy, today reported financial results for the Company's fourth quarter and full year ended December 31, 2025, and provided a corporate update.

"2025 was a strong year of executing upon our goals, and we continue to move all our programs forward this year. As we progress our clinical development pipeline, we have strategically strengthened our clinical and drug development expertise with Craig Tendler, M.D., providing the strategic and operational services consistent with those of a Chief Medical Officer to oversee clinical development strategy and operations of the company's pipeline, including our VISTA inhibiting antibody, TBS-2025," said Dr. James Bianco, President and CEO of TuHURA Biosciences. "Craig brings a depth of experience that is invaluable to us as we look forward to several targeted key milestones in our VISTA program this year. Our IFx-2.0 Phase 3 study in front-line Merkel Cell Carcinoma (MCC) continues to enroll, and we now anticipate completing enrollment in mid-2027. Additionally, we continue to make important advancements toward preclinical proof-of-concept in our first-in-class immune modulating antibody drug conjugates (ADC) program and anticipate presenting new data at a scientific conference later this year."

Dr. Bianco continued, "We are grateful to have the unwavering support of our shareholders, who are committed to supporting our programs and realizing the potentially meaningful opportunity each one addresses."

Corporate Highlights

• Initiated a randomized Phase 3 Accelerated Approval Trial for IFx-2.0 in first line treatment of patients with advanced or metastatic Merkel Cell Carcinoma (MCC) as adjunctive therapy to Keytruda® (pembrolizumab). Phase 3 study trial being conducted under a Special Protocol Assessment (SPA) agreement with U.S. Food and Drug Administration (FDA). Primary endpoint of Overall Response Rate (ORR) qualifies for accelerated approval process. Key secondary endpoint of Progression Free Survival (PFS) may satisfy the requirement for a post confirmatory trial, converting accelerated approval to regular approval.
  
  
• Initiated Phase 1b/2a Study of IFx-2.0 as an adjunctive therapy to Keytruda® (pembrolizumab) in first line treatment for metastatic Merkel Cell Carcinoma of Unknown Primary Origin (MCCUP). Trial designed to evaluate the safety and feasibility of IFx-Hu2.0 in combination with Keytruda® when administered via Interventional Radiology (IR) in patients with deep- seated tumors without associated cutaneous tumors.
  
  
• Closed acquisition of Kineta gaining rights to TBS-2025, a novel VISTA inhibiting antibody, for $10.5 million.
  
  
• Raised gross proceeds of $21.2 million in registered direct offerings and private placements
  
  
• Presented data demonstrating the Delta Opioid Receptor (DOR) as a new target in overcoming acquired resistance to immune checkpoint inhibitors at ASH. Selected for Oral Presentation by the Scientific Committee of American Society of Hematology new scientific evidence that DOR is expressed on tumor-associated Myeloid-Derived Suppressor Cells (MDSCs), and its inhibition decreases immune suppressing capabilities of MDSCs by downregulating expression of multiple genes associated with MDSC induced immunosuppression. Data also presented in the poster session demonstrated that the DOR is also expressed on tumor associated macrophages (TAMs) and DOR inhibition appears to reverse TAM mediated T cell suppression with the potential to overcome resistance to checkpoint inhibitors and other cancer immunotherapies.

About TuHURA Biosciences, Inc. 
TuHURA Biosciences, Inc. (Nasdaq: HURA) is a Phase 3 immuno-oncology company developing novel technologies to overcome primary and acquired resistance to cancer immunotherapy, two of the most common reasons cancer immunotherapies fail to work or stop working in the majority of patients with cancer.

TuHURA's lead innate immune agonist, IFx-2.0, is designed to overcome primary resistance to checkpoint inhibitors. TuHURA has initiated a single randomized placebo-controlled Phase 3 registration trial of IFx-2.0 administered as an adjunctive therapy to Keytruda® (pembrolizumab) compared to Keytruda® plus placebo in first-line treatment for advanced or metastatic Merkel Cell Carcinoma.

In addition to its innate immune agonist product candidates, TuHURA acquired TBS-2025 in its merger with Kineta Inc. on June 30, 2025. TBS-2025 is a VISTA inhibiting mAb moving into Phase 2 development in mutNPM1 r/r AML.

In addition, TuHURA is leveraging its Delta Opioid Receptor technology to develop first-in-class, bi-specific antibody drug conjugates targeting Myeloid Derived Suppressor Cells to inhibit their immune-suppressing effects on the tumor microenvironment to prevent T cell exhaustion and acquired resistance to checkpoint inhibitors and cellular therapies.
