Official title
A Randomized, Phase 2, Double-blind Study to Evaluate the Efficacy of Dostarlimab Plus Chemotherapy Versus Pembrolizumab Plus Chemotherapy in Metastatic Non-Squamous Non-Small Cell Lung Cancer
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
NSCLC comprises of approximately 84 percent (%) of all lung cancers and is often diagnosed at advanced stage due to poor prognosis. Dostarlimab is an immunoglobulin G (IgG)4 kappa humanized monoclonal antibody (mAb) that binds with high affinity to programmed cell death protein 1 (PD 1), resulting in inhibition of binding to programmed death ligand 1 (PD L1) and programmed death ligand 2 (PD L2). This study aims to compare the efficacy and safety PD-1 inhibitors dostarlimab and pembrolizumab, when administered in combination with chemotherapy (pemetrexed, cisplatin and carboplatin), in participants with non-squamous NSCLC without a known sensitizing epidermal growth factor receptor (EGFR), anaplastic lymphoma kinase (ALK), or receptor tyrosine kinase-1 (ROS-1) mutation, BRAF V600E mutation, or other genomic aberration for which an approved targeted therapy is available. A total of approximately 240 participants will be enrolled in the study for a period of 5 years.
