Rhea-AI Filing Summary

Oncolytics Biotech Inc. has scheduled a Type C meeting with the U.S. FDA on April 16, 2026 to discuss a potential single-arm registrational study of pelareorep plus a checkpoint inhibitor in second-line and later squamous cell anal carcinoma (SCAC).

The company plans to propose a pivotal trial enrolling approximately 60–70 patients, using objective response rate as the primary endpoint to support potential full approval. In Cohort 4 of the GOBLET study, pelareorep plus a checkpoint inhibitor achieved an approximately 30% objective response rate and a median duration of response of 17 months in late-line SCAC, compared with real-world response rates of about 10–14% and a median duration of response of roughly 9.5 months.

Oncolytics highlights SCAC as a rare cancer with limited second-line and later treatment options and notes external estimates of about 54,000 anal cancer cases globally each year, with the anal cancer market projected to reach $2.3 billion by 2035.

Insights

Oncolytics is seeking FDA alignment on a single-arm pivotal SCAC trial based on encouraging prior data.

Oncolytics Biotech is moving pelareorep toward a potential registrational path in anal cancer by engaging the FDA via a Type C meeting on April 16, 2026. The company aims to agree on a single-arm pivotal design in second-line and later SCAC, a setting with few alternatives.

The contemplated study would enroll about 60–70 patients with objective response rate as the primary endpoint. Supporting this proposal, Cohort 4 of the GOBLET study showed an approximately 30% objective response rate and 17‑month median response duration, compared with real‑world benchmarks of 10–14% and 9.5 months.

Regulatory outcomes will depend on the FDA’s acceptance of a single‑arm design and the strength of future trial data. Subsequent disclosures after the April 16, 2026 meeting may clarify the agreed sample size, statistical analysis plan, and next development milestones for pelareorep in SCAC.

Type C meeting regulatory
"scheduled a Type C meeting with the U.S. Food and Drug Administration"
single-arm pivotal study clinical
"potential to initiate a single-arm pivotal study evaluating pelareorep"
A single-arm pivotal study is a late-stage clinical trial in which every participant receives the experimental treatment and there is no randomized control group; it is designed to provide the main evidence regulators use to decide on approval. For investors, this matters because such trials can be faster or necessary for rare conditions but leave greater uncertainty about how much benefit or risk is due to the treatment versus other factors — like judging a new recipe without tasting the old one — which can affect approval odds and future market value.
objective response rate clinical
"with objective response rate (“ORR”) as the primary endpoint"
The objective response rate (ORR) is the percentage of patients in a clinical trial whose tumors measurably shrink or disappear according to preset rules. Investors use it as a quick, objective signal of a drug’s ability to produce a clear treatment effect—like counting how many plants visibly respond after applying a new fertilizer—and higher ORR can improve odds of regulatory approval, commercial success, and company valuation.
checkpoint inhibitor clinical
"pelareorep in combination with a checkpoint inhibitor in patients"
A checkpoint inhibitor is a type of medicine that helps the immune system spot and attack cancer by blocking proteins that act like brakes on immune cells. For investors, these drugs matter because clinical trial results, regulatory approvals, safety profiles and market demand can quickly change a developer’s revenue and valuation; think of them as releasing the brakes on the immune system—potentially high reward but with safety and trial-risk consequences.
Fast Track designation regulatory
"pelareorep has received Fast Track designation from the FDA for colorectal and pancreatic cancer"
A "fast track designation" is a process that speeds up the review and approval of a product or project, allowing it to reach the market or be completed more quickly than usual. For investors, it can signal that a product may become available sooner, potentially leading to earlier revenue or benefits, and indicating a priority status that might influence company performance and market opportunities.
immunologically “cold” tumors “hot” clinical
"converting immunologically “cold” tumors “hot” through the activation of innate and adaptive immune responses"

Oncolytics Biotech® Announces Type C FDA Meeting to Discuss Single-arm Registrational Pathway for Pelareorep in Anal Cancer

SAN DIEGO, CA, April 6, 2026 – Oncolytics Biotech® Inc. (Nasdaq: ONCY) (“Oncolytics” or the “Company”), a clinical-stage immunotherapy company developing pelareorep, an investigational, systemically delivered immunotherapy that has been shown to activate innate immune-sensing pathways, today announced that it has scheduled a Type C meeting with the U.S. Food and Drug Administration (“FDA”) on April 16, 2026, to discuss a potential registrational development path in anal cancer.

The meeting will focus on the potential to initiate a single-arm pivotal study evaluating pelareorep in combination with a checkpoint inhibitor in patients being treated with second-line and later therapy for squamous cell anal carcinoma (“SCAC”). Patients will have received a checkpoint inhibitor and chemotherapy in the first-line, which means all patients treated in this study would have no alternative approved therapies available at this stage of treatment. The Company intends to discuss a study design enrolling approximately 60 to 70 patients with objective response rate (“ORR”) as the primary endpoint to support a potential full approval.

Pelareorep, in combination with a checkpoint inhibitor, has demonstrated encouraging clinical activity in SCAC. In Cohort 4 of the GOBLET study, the combination achieved approximately 30% ORR with a median duration of response in late-line patients of 17 months. These results compare favorably to real-world outcomes, where response rates are approximately 10-14% with a median duration of response of approximately 9.5 months in this setting.1

“We believe this upcoming FDA meeting is a critical step in advancing pelareorep toward a potential registration pathway in anal cancer,” said Jared Kelly, Chief Executive Officer of Oncolytics. “Our goal is to align with the FDA on the statistical analysis plan and sample size for a potential pivotal single-arm study in second-line and later SCAC. In a setting with limited approved therapies, we believe the strength and durability of our data support this approach, and recent regulatory discussions in oncolytic virus development underscore the importance of demonstrating clear, durable clinical benefit with checkpoint inhibition. With few late-line options and no confounding checkpoint inhibitor data, SCAC offers a clearer efficacy signal and a potentially more efficient path to approval for pelareorep.”

SCAC is a rare cancer with limited treatment options in the second-line and later setting, and outcomes remain poor following progression on first-line treatment. The World Health Organization estimates that there are approximately 54,000 cases of anal cancer globally each year, and the anal cancer market is expected to double to $2.3 billion from 2025 to 2035.2, 3
