The FDA has extended the review period for a supplemental biologics license application (sBLA) for single-agent pembrolizumab (Keytruda) for the frontline treatment of patients with locally advanced or metastatic nonsquamous or squamous non–small cell lung cancer (NSCLC) with a PD-L1 expression (tumor proportion score [TPS]) level of ≥1% and no EGFR
genomic tumor aberrations.
In addition, these patients experienced fewer severe adverse events (AEs; 17.8% vs. 41%). Treatment-related AEs occurred more often in those who received chemotherapy (89.9% vs 62.7%) compared with pembrolizumab, which led to discontinuation in 9.4% and 9% of patients, respectively.
