Oncolytics announced that a Type C meeting with the FDA has resulted in alignment on the design of a pivotal clinical study to support approval of pelareorep in patients with unresectable metastatic squamous cell carcinoma of the anal canal. "We want to thank the FDA for its very clear guidance and helping us create an efficient pathway for pelareorep in a disease that is desperate for new treatments," said Jared Kelly, Chief Executive Officer of Oncolytics. "While a single-arm study was possible in this setting, following a productive discussion with the FDA and in consideration of recent regulatory decisions regarding similar studies, we have aligned on a randomized controlled trial designed to potentially support both accelerated approval and full approval within the same study. This approach directly addresses relevant and rigorous evidentiary standards while allowing for approval based on multiple endpoint assessments." The company plans to incorporate FDA feedback into the final protocol, which is expected to be a single, randomized controlled trial for which accelerated approval and full approval could be applied at different points in time.

About ONCY
Oncolytics Biotech Inc. is a clinical-stage biotechnology company developing pelareorep, an intravenously delivered immunotherapeutic agent that activates the innate and adaptive immune systems and weakens tumor defense mechanisms. This improves the ability of the immune system to fight cancer, making tumors more susceptible to a broad range of oncology treatments. It acts by inducing anti-cancer immune responses and promotes an inflamed tumor phenotype, turning cold tumors hot through innate and adaptive immune responses to treat a variety of cancers. The Company is also advancing its programs in hormone receptor-positive / human epidermal growth factor 2-negative (HR+/ HER2-) advanced and metastatic breast cancer (mBC) and metastatic pancreatic ductal adenocarcinoma (PDAC) to registration-enabled clinical studies. In addition, it is exploring opportunities for registrational programs in other gastrointestinal cancers through its GOBLET platform study.

Oncolytics Biotech Presents New Data at ASCO Meeting
- Clinical Trial Data Presentation: Oncolytics Biotech will present translational data from the GOBLET and AWARE-1 trials at the 2026 ASCO Annual Meeting, further validating the potential of its immunotherapy pelareorep in treating difficult cancers, likely attracting investor interest.
- Mechanism of Immune Response: The research indicates that pelareorep enhances immune responses against KRAS-mutant tumors by expanding pre-existing tumor-reactive immune cells rather than introducing new antigens, potentially providing new insights for future treatment strategies.
- Efficacy Metrics Improvement: In pancreatic cancer studies, the observed expansion of antiviral T cells correlated with reductions in tumor volume post-treatment, demonstrating pelareorep's ability to activate immune responses within the tumor microenvironment, which may improve patient outcomes.
- Strategic Partnerships and Development: Oncolytics is actively pursuing strategic partnerships to accelerate the development of pelareorep, particularly in colorectal and pancreatic cancers where the FDA has granted Fast Track designation, indicating the company's focus on market opportunities.

GT Biopharma Initiates Phase 1 Trial of GTB-5550 for Solid Tumors
- Trial Launch: On May 14, 2026, GT Biopharma announced that the first patient has been dosed in the Phase 1 trial of GTB-5550, a B7-H3-targeted natural killer cell engager, marking a significant advancement in treating historically resistant solid tumors.
- Innovative Dosing Method: GTB-5550 is the first TriKE® molecule tested with subcutaneous dosing, administered for five consecutive days in the abdominal area during each four-week cycle, which is expected to enhance patient compliance and reduce treatment-related side effects.
- Broad Tumor Type Coverage: The trial is designed as a basket study encompassing seven solid tumor types, including prostate, ovarian, breast, head and neck, non-small cell lung, pancreatic, and bladder cancers, indicating the potential applicability of GTB-5550 across multiple difficult-to-treat tumors.
- Strong Market Demand: With prostate and pancreatic cancers historically unresponsive to standard immunotherapies, GTB-5550 is poised to address this significant unmet medical need, enhancing the company's competitiveness in the rapidly evolving immuno-oncology market.

Oncolytics Biotech Aligns with FDA on Pivotal Study Design for Pelareorep
- Clinical Trial Alignment: Oncolytics Biotech has reached an agreement with the FDA on the design of a pivotal clinical study to support the approval of pelareorep for patients with unresectable metastatic squamous cell carcinoma of the anal canal, indicating the company's proactive progress in developing new therapies.
- Significant Patient Need: Over 10,000 patients are affected by SCAC annually in the U.S., and with no FDA-approved treatment options available after first-line chemotherapy or checkpoint inhibitor therapy, the market potential for pelareorep is substantial.
- Enhanced Efficacy: In a recent study, the combination of pelareorep with a checkpoint inhibitor achieved a median duration of response of 15.5 months compared to 9.5 months with the current standard of care, demonstrating its effectiveness in treating SCAC.
- Strategic Partnership Opportunities: Oncolytics plans to incorporate FDA feedback into the final protocol, with a randomized controlled trial expected to apply for both accelerated and full approval at different points in time, further advancing its strategic development in cancer immunotherapy.
