Genentech’s Tecentriq OK’d for Breast Cancer
FDA has granted Genentech accelerated approval for Tecentriq (atezolizumab) plus chemotherapy (Abraxane [paclitaxel protein-bound particles for injectable suspension (albumin-bound); nab-paclitaxel]) for treating adults with unresectable locally advanced or metastatic triple-negative breast cancer in people whose tumors express PD-L1. Approval was based on data showing favorable progression-free survival, the company says.
Data from the Phase 3 IMpassion130 study showed that Tecentriq plus nab-paclitaxel significantly reduced the risk of disease worsening or death by 40% compared with nab-paclitaxel alone in the target patient population. Overall survival results were “immature” with 43% of events in all randomized patients (intent-to-treat), and further data will be submitted to FDA when available, Genentech says.
Safety in the Tecentriq plus nab-paclitaxel arm appeared consistent with the known safety profiles of the individual therapies, and no new safety signals were identified with the combination, the company says. The most common side effects recorded in patients on the combination therapy were low white blood cells, tingling or numbness in the hands and feet, neutrophil count decreased, feeling tired, low red blood cells, low blood potassium level, pneumonia and increased blood level of a liver enzyme.
