Study of CAbozantinib in Combination with AtezolizumaB for Muscle-Invasive BladdEr Cancer

This is an open-label phase II study assessing the activity of cabozantinib combined with atezolizumab in patients with resectable muscle-invasive urothelial carcinoma who are ineligible for cisplatin-based therapy or decline cisplatin-based therapy. Each cycle equals 21 days. The dose of atezolizumab is 1200 mg IV flat dose every 3 weeks (Day 1) plus cabozantinib 40 mg orally daily (Day 1 through Day 21). Patients will receive three cycles of treatment prior to cystectomy unless they discontinue treatment for unacceptable toxicity or progressive disease by RECIST v1.1 or withdraw consent.
