Individuals with versus without prior receipt of thoracic radiation had a higher incidence of any (63 vs 40%) and treatment-related (13 vs 1%) pulmonary toxicity, but the safety profile was considered acceptable by the researchers. The association between higher PD-L1 levels and better outcomes was also observed in this analysis, which appeared in The Lancet Respiratory Medicine in March 2019.Ī secondary analysis of the trial – published in The Lancet Oncology in May 2017 – showed significantly better progression-free survival (PFS) and OS for participants who had previously received radiotherapy relative to those who had not. Three-year results from the trial pointed to a durable effect of the agent on OS, with median OS durations of 22.3 and 10.5 months among treatment-naïve and previously treated participants, respectively. Overall survival (OS) data on the treatment-naïve participants of the same trial, published in the Annals of Oncology in April 2017, showed a median OS time of 22.1 months, with greater benefits for those with a PD-L1 tumor proportion score (TPS) of at least 50%. They showed that pembrolizumab given at a dose of 2 or 10 mg/kg every 3 weeks or 10 mg/kg every 2 weeks was well tolerated and had antitumor activity regardless of whether patients had received prior therapy or not. The results of the NSCLC cohort of the KEYNOTE-001 trial were published in The New England Journal of Medicine in May 2015. Patient population: Locally advanced or metastatic NSCLC with PD-L1 positivity ![]() Where a trial comprises multiple solid tumor cohorts, we focus on just the NSCLC and SCLC cohorts in this guide. Here we provide a quick guide to the non-small-cell lung cancer (NSCLC) and small-cell lung cancer (SCLC) trials sponsored by the drug manufacturer Merck Sharp & Dohme. The PD-1 inhibitor pembrolizumab is being investigated in multiple KEYNOTE trials across different tumor types, either alone or as part of various combinations, leading to a prodigious amount of information. ![]()
