The first line treatment of urothelial carcinoma is a platinum-based chemotherapy. This treatment is efficient with a response rate > 50 % but the progression-free survival is short (7.7 months) and the chemotherapy is too toxic to be used in a prolonged time. Traditionally, maintenance chemotherapy refers to the utilization of regimens with less toxicity after the initial upfront treatment. This concept has already been efficient with PARP inhibitors in ovarian carcinoma and more recently with durvalumab in lung carcinoma. The prevalence of somatic mutations in homologous recombination genes in UC as well as their association with platinum sensitivity suggests Talazoparib to be a target for a maintenance treatment of urothelial carcinoma. Moreover, there is a strong rational with both pre-clinical and clinical data to associate Avelumab and Talazoparib. This appears all the more relevant that Avelumab has already demonstrated its efficacy in urothelial carcinoma (after platinum-based chemotherapy failure). In this context, the sponsorpropose a phase 2 study to assess the antitumor activity of the combination of Avelumab plus Talazoparib in metastatic urothelial carcinoma in maintenance therapy after platinum-based chemotherapy. Considering the doubts about the best molecular predictive factors of Talazoparib and Avelumab, the sponsor willingly propose a non-selective study, without molecular screening. Tumors will be selected according to the platinum sensitivity which has the advantage to exclude poor prognosis tumors and will allow increasing the HRD tumor population.
