KEYNOTE-042 leads to first-line pembrolizumab approval for stage III NSCLC
medwireNews: The US FDA has approved the use of pembrolizumab as a first-line therapy for patients with stage III non-small-cell lung cancer (NSCLC) that have a PD-L1 tumor proportion score (TPS) of at least 1%.
Pembrolizumab may now be given to patients who are not candidates for surgery or definitive chemoradiation and whose tumors do not have EGFR or ALK aberrations. The PD-L1 TPS must be determined using an FDA-approved assay.
The decision is based on findings from the KEYNOTE-042 trial which showed that single-agent pembrolizumab achieved significantly better overall survival than platinum-based chemotherapy in patients with treatment-naïve locally advanced or metastatic disease.
