Summary

This phase II trial tests two drugs, lurbinectedin and avelumab, in people with a rare and aggressive bladder cancer called small cell carcinoma. Participants who have already had a drug like avelumab will receive only lurbinectedin; others will get both. The study aims to see if these drugs can shrink tumors and control the disease for longer.
