These 2 responders had both a known HRD deleterious mutation (one BRCA2, one ATM). Disease control rate was 69.2% (18/26). Median radiographic PFS was 6.78 months (95% CI 4.28-9.01) and median OS 10.56 months (95% CI 6.68-NR)...Avelumab plus carboplatin has an acceptable safety profile. Overall clinical benefit was seen in almost 70% of patients and was associated with a prolonged OS given the heavily pretreated population.
