Clinical Trial Summary

The purpose of this study is to describe the safety and tolerability of Durvalumab plus Tremelimumab followed by concurrent Durvalumab plus bladder radiation in patients with localized muscle invasive urothelial carcinoma of the bladder, who are either Decipher-Non-Basal OR Decipher-Basal and cisplatin-ineligible. Eligible subjects will receive 2 cycles of Durvalumab plus Tremelimumab followed by imaging and cystoscopy. Subjects whose cancer responds or is stable will receive a combination of 2 cycles of Durvalumab plus 6.5 weeks of radiation to the bladder followed by imaging and a TURBT. Subjects whose cancer continues to respond and meets certain criteria will continue to receive Durvalumab for up to 12 months from initial dose or until the cancer recoccurs or progresses, whichever occurs earlier. During this time, subjects may also receive intravesicular therapy if clinically indicated. Subjects will be followed for 5 years from initial dose.

At the completion of radiation, eligible subjects may continue to receive durvalumab for a maximum of one year from the date of their initial dose. Durvalumab will be administered intravenously at a dose of 1500 mg on the first day of each cycle.

Radiation:
• Bladder radiation
