Cancer patients who respond to avelumab can keep taking it in this Follow-Up study
NCT ID NCT05059522
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study offers continued access to the cancer drug avelumab (and sometimes other drugs) for people with advanced cancers like lung, ovarian, or bladder cancer who are already seeing benefits from a previous Pfizer-sponsored trial. About 77 participants will be followed for safety and survival. The goal is not to test new effectiveness, but to allow ongoing treatment and monitor side effects.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- avelumab (with possible combinations: lorlatinib, talazoparib, pemetrexed, axitinib, CMP 001, utomilumab, PF04518600)
- What this could lead to
- If successful, this study allows patients who are already benefiting from avelumab to keep receiving it, potentially extending their disease control.
- What could go wrong
- This is an open-label continuation study, not a new treatment test. It does not prove the drug works for new patients, and side effects may still occur.
This is an AI summary of the original study and may miss details. Read our disclaimer.
