Genentech Reports Disappointing Phase 3 Tecentriq Results

Share

Genentech says its Phase 3 study IMvigor211 that evaluated Tecentriq (atezolizumab) in people with locally advanced or metastatic urothelial cancer (mUC) whose disease progressed during or after treatment with a platinum-based chemotherapy (previously treated) did not meet its primary endpoint (overall survival) compared to chemotherapy. “The results observed in people treated with Tecentriq in IMvigor211 were generally consistent with those observed in a similar group of people in the Phase 2 IMvigor210 study,” the company says. “The IMvigor211 data will be further examined in an effort to better understand these results, including the initial observation that the chemotherapy arm results were better than study design assumptions. Full data from IMvigor211 will be presented later this year.”


Tecentriq currently has accelerated approval by FDA based on tumor response rate and duration of response in IMvigor210 for treating people with locally advanced or mUC who have disease progression during or following platinum-based chemotherapy, or whose disease has worsened within 12 months of receiving platinum-based chemotherapy before or after surgery. IMvigor211 was a randomized pivotal study designed to support full approval globally and to serve as the confirmatory study to convert the accelerated approval to full approval in the U.S. The therapy was recently granted accelerated approval as an initial treatment for people with locally advanced or mUC who are not eligible for cisplatin chemotherapy. A Phase 3 confirmatory study, IMvigor130, is currently ongoing in this population.
