What was measured

Patients enrolled will have non-measurable disease based on imaging at baseline. Patients will be assessed for a response after 6 months of treatment using the results of a biopsy and cytology test. A complete response (CR) is defined as having a negative biopsy and negative urine cytology at 6 months from registration after finishing of concurrent RT and immunotherapy. Imaging of abdomen and pelvis confirming no systemic disease within 4 weeks of cystoscopy will be completed. The proportion of patients reporting a CR is reported here with confidence intervals for the true success proportion using the binomial distribution.

Analysis population: All patients who registered and began protocol treatment are included in this analysis.

Groups in this outcome

Avelumab and Cisplatin IV

Participants received avelumab IV over 60 minutes every 14 days for a total of 10 courses in the absence of disease progression or unacceptable toxicity. Beginning 29 days after the first dose of avelumab, participants received 35 mg/m\^2/day cisplatin IV starting on day 1 of courses 3-5 for up to 6 weeks in the absence of disease progression or unacceptable toxicity.
