US Food and Drug Administration Approval Summary: Nivolumab Plus Platinum-Doublet Chemotherapy for the Neoadjuvant Treatment of Patients With Resectable Non–Small-Cell Lung Cancer
Cette étude analyse les données de l'essai ayant conduit la "Food and Drug Administration" à autoriser l'utilisation du nivolumab en combinaison avec un doublet de chimiothérapie à base de sels de platine en traitement adjuvant chez des patients atteints d'un cancer résécable du poumon non à petites cellules
PURPOSE: On March 4, 2022, the US Food and Drug Administration (FDA) approved nivolumab plus platinum-doublet chemotherapy for the neoadjuvant treatment of patients with resectable non–small-cell lung cancer (NSCLC). We discuss the FDA's review of the key data and regulatory considerations supporting this approval. PATIENTS AND METHODS: The approval was based on the results of CheckMate 816, an international, multiregional, active-controlled trial that randomly assigned 358 patients with resectable NSCLC, stage IB (≥4 cm) to IIIA (N2) per the American Joint Committee on Cancer seventh staging edition to receive either nivolumab plus platinum-doublet or platinum-doublet chemotherapy alone for three cycles before planned surgical resection. The major efficacy end point that supported this approval was event-free survival (EFS). RESULTS: At the first planned interim analysis (IA), the hazard ratio (HR) for EFS was 0.63 (95% CI, 0.45 to 0.87; P = .0052; statistical significance boundary = .0262) favoring the nivolumab plus chemotherapy arm; the median EFS was 31.6 months (95% CI, 30.2 to not reached) in the nivolumab plus chemotherapy arm versus 20.8 months (95% CI, 14.0 to 26.7) in the chemotherapy-only arm. At the time of a prespecified IA for overall survival (OS), 26% of patients had died, and the HR for OS was 0.57 (95% CI, 0.38 to 0.87; P = .0079; statistical significance boundary = .0033). Eighty-three percent of patients in the nivolumab-containing arm versus 75% in the chemotherapy-only arm received definitive surgery. CONCLUSION: This approval, the first for any regimen for the neoadjuvant treatment of NSCLC in the United States, was supported by a statistically significant and clinically meaningful improvement in EFS with no evidence of detriment in OS or negative impact on patients' receipt and timing of surgery or surgical outcomes.
