Merck & Co. said Monday that Japanese regulators approved Keytruda (pembrolizumab) for the treatment of certain patients with PD-L1-positive unresectable advanced/recurrent non-small-cell lung cancer (NSCLC). The anti-PD-1 therapy, which will be promoted with Taiho Pharmaceutical in the country, has been cleared in the first- and second-line treatment settings.
According to Merck, the approval was supported by data from the KEYNOTE-024 and KEYNOTE-010 studies. In the KEYNOTE-024 trial, the results of which were presented in October, Keytruda was associated with significant improvements in progression-free survival and overall survival (OS) versus platinum-base chemotherapy in patients with PD-L1-positive NSCLC. Additionally, in the KEYNOTE-010 trial, the therapy was shown to prolong OS versus chemotherapy in patients with PD-L1-expressing NSCLC.

Keytruda was approved by the European Commission in August for use in patients with PD-L1-positive locally advanced or metastatic NSCLC who received at least one prior chemotherapy regimen, with the European Medicines Agency's Committee for Medicinal Products for Human Use adopting a positive opinion on first-line use last week. The therapy was cleared by the FDA for the first-line treatment of patients with NSCLC whose tumours have high PD-L1 expression in October, having been authorised the year before for patients whose disease has progressed after prior treatment.
