FDA Grants First Approval to First-Line Therapy for Advanced Anal Cancer
- The FDA approved retifanlimab-dlwr in May 2025 as the first-line treatment for inoperable advanced squamous cell anal carcinoma in the US.
- This approval comes after a 2021 denial for second-line therapy and is supported by encouraging outcomes reported at ESMO 2024 from the phase 3 study POD1UM-303/InterAACT2 evaluating retifanlimab in combination with chemotherapy.
- The trial demonstrated that adding retifanlimab to carboplatin and paclitaxel significantly lowered the chance of disease worsening or death by 37%, resulting in a median progression-free survival of 9.3 months.
- Marwan Fakih, MD, noted that patients historically faced poor 5-year survival and limited options, making this approval a significant new option for this challenging cancer.
- Zynyz’s approval is expected to improve treatment accessibility for anal cancer patients and may accelerate its use globally while safety follow-up and regulatory reviews continue.
