Merck has announced that the European Commission (EC) has granted its Decision for Keytruda (pembrolizumab) for its extension of indication in combination with platinum-containing chemotherapy as neoadjuvant treatment, then continued as monotherapy as adjuvant treatment, for resectable non-small cell lung cancer (NSCLC) at high risk of recurrence in adults.
The approval was based on results from the Phase 3 KEYNOTE-671 trial. At a median follow-up of 29.8 months (range, 0.4 to 62.0 months), KEYTRUDA plus chemotherapy in the neoadjuvant setting followed by KEYTRUDA as monotherapy after surgical resection significantly improved overall survival (OS), reducing the risk of death by 28% (HR=0.72 [95% CI, 0.56-0.93]; one-sided p=0.00517) in patients with resectable stage II, IIIA or IIIB NSCLC versus placebo plus chemotherapy in the neoadjuvant setting followed by placebo after surgical resection, regardless of PD-L1 expression. For patients who received the KEYTRUDA-based regimen, median OS was not reached (95% CI, NR-NR) versus 52.4 months (95% CI, 45.7-NR) for patients who received the chemotherapy-placebo regimen. The KEYTRUDA-based regimen also improved event-free survival (EFS), reducing the risk of disease recurrence, progression or death by 41% (HR=0.59 [95% CI, 0.48-0.72]) compared to the chemotherapy-placebo regimen. For patients who received the KEYTRUDA-based regimen, median EFS was improved by nearly two and a half years compared to the chemotherapy-placebo regimen (47.2 months [95% CI, 32.9-NR] versus 18.3 months [95% CI, 14.8-22.1], respectively).
