Genentech, a member of the Roche Group have announced that the U.S. Food and Drug Administration (FDA) has approved Tecentriq (atezolizumab) as adjuvant treatment following surgery and platinum-based chemotherapy for adults with Stage II-IIIA non-small cell lung cancer (NSCLC) whose tumors express PD-L1≥1%, as determined by an FDA-approved test.
Tecentriq is now the first and only cancer immunotherapy available for adjuvant treatment of NSCLC.
Approval is based on results from an interim analysis of the Phase III IMpower010 study.
IMpower010 is a Phase III, global, multicenter, open-label, randomized study evaluating the efficacy and safety of Tecentriq compared with BSC, in participants with Stage IB-IIIA NSCLC (UICC/AJCC 7th edition), following surgical resection and up to 4 cycles of adjuvant cisplatin-based chemotherapy. The study randomized 1,005 people with a ratio of 1:1 to receive either Tecentriq for 1 year (16 cycles), unless disease recurrence or unacceptable toxicity occurred, or BSC. The primary endpoint is investigator-determined DFS in the PD-L1-positive Stage II-IIIA, all randomized Stage II-IIIA and intent-to-treat (ITT) Stage IB-IIIA populations. Key secondary endpoints include overall survival (OS) in the overall study population, ITT Stage IB-IIIA NSCLC.
Results showed that treatment with Tecentriq following surgery and platinum-based chemotherapy reduced the risk of disease recurrence or death by 34% (hazard ratio [HR]=0.66, 95% CI: 0.50-0.88) in people with Stage II-IIIA (UICC/AJCC 7th edition) NSCLC whose tumors express PD-L1≥1%, compared with best supportive care (BSC). Safety data for Tecentriq were consistent with its known safety profile and no new safety signals were identified. Fatal and serious adverse reactions occurred in 1.8% and 18%, respectively, of patients receiving Tecentriq. The most frequent serious adverse reactions (>1%) were pneumonia (1.8%), pneumonitis (1.6%), and pyrexia (1.2%).
