简要总结
This trial will include metastatic urothelial carcinoma patients who progressed during or after treatment with anti-PD(L)1 therapy and have been treated by a platinum-containing regimen, or are cisplatin-ineligible. Patients will receive either paclitaxel in combination with durvalumab (anti-PDL-1) and a single dose (300 mg) of tremelimumab (anti-CTLA4), or paclitaxel with only a high dose of tremelimumab (750 mg). Tremelimumab (750 mg), without paclitaxel will be used as a comparison arm.
A run-in safety phase will be followed by a non-comparative 3-arm randomized study with a Simon's 2-stage optimal design.

主要结局
Overall response rate (ORR), defined as the proportion of participants whose confirmed best overall response is either a PR or CR after treatment with paclitaxel and a high dose of tremelimumab based upon the RECIST v1.1 guidelines.
时间窗: Final ORR will be determined after the confirmatory scan of the last patient, which is scheduled up to 21 weeks after start of treatment of the final patient
Tumor evaluation will take place using CT-Chest and abdomen, based on the Response Evaluation Criteria in Solid Tumors, version 1.1 (RECIST 1.1) guidelines. The first evaluation will take place 12 weeks after initiating treatment. After this initial scan, tumor evaluation will take place every 8 weeks for the first year. After the first year, tumor evaluation will be done every 12 weeks.
