Priority Review for Tecentriq Plus Chemo in Breast Cancer
FDA has accepted for priority review a Genentech supplemental BLA for Tecentriq (atezolizumab) plus chemotherapy (Abraxane [albumin-bound paclitaxel; nab-paclitaxel]) for first-line treatment of unresectable locally advanced or metastatic triple-negative breast cancer (TNBC) in people whose disease expresses the PD-L1 protein, as determined by biomarker testing. The agency has set a user fee review action target of 3/12/2019.
The submission is based on data from the Phase 3 IMpassion130 study, which showed that the combination significantly reduced the risk of disease worsening or death (progression-free survival) compared with nab-paclitaxel alone in all randomized patients, Genentech says. However, the company says that an interim analysis did not demonstrate statistical significance for overall survival in the intent-to-treat population, but the combination did show a clinically meaningful overall survival improvement in the PD-L1-positive population. Safety in the Tecentriq plus nab-paclitaxel arm appeared to track the known safety profiles of the individual therapies, it adds, with no new safety signals being identified with the combination.
Currently, Genentech says it has seven ongoing Phase 3 studies investigating Tecentriq in TNBC, including early and advanced stages of the disease.
