Genentech announced that the Phase III IMvigor010 study evaluating Tecentriq (atezolizumab) as an adjuvant (after surgery) monotherapy treatment did not meet its primary endpoint of disease-free survival (DFS) compared to observation in people with muscle-invasive urothelial cancer (MIUC). Safety for Tecentriq appeared consistent with the known safety profile of the medicine, and no new safety signals were identified.

IMvigor101 was a global, open label, randomized, controlled study designed to evaluate the efficacy and safety of adjuvant treatment with Tecentriq compared with observation in 809 people with MIUC at high risk for recurrence following resection. The primary endpoint was DFS as assessed by investigator, which is defined as the time from randomization to invasive urothelial cancer recurrence or death.  

About Tecentriq (atezolizumab) 

Tecentriq is a monoclonal antibody designed to bind with a protein called PD-L1. Tecentriq is designed to bind to PD-L1 expressed on tumor cells and tumor-infiltrating immune cells, blocking its interactions with both PD-1 and B7.1 receptors. By inhibiting PD-L1, Tecentriq may enable the re-activation of T cells. Tecentriq may also affect normal cells.

About bladder cancer 

According to the American Cancer Society (ACS), it is estimated that more than 81,000 Americans will be diagnosed with bladder cancer in 2020. Urothelial cancer is the most common type of bladder cancer, accounting for about 90-95% of all cases. MIUC is a type of urothelial cancer that has spread into the muscle wall of the bladder, ureter, or renal pelvis. Approximately 25% of people newly diagnosed with bladder cancer are diagnosed with muscle-invasive disease, which is associated with a poorer prognosis than non-MIUC.
