Trial overview
Official title: A Phase 2, Randomized, Open-label, Platform Study Utilizing a Master Protocol to Evaluate Novel Immunotherapy Combinations in Participants with Previously Untreated, Locally Advanced/Metastatic, Programmed Death Ligand 1-Selected Non-Small-Cell Lung Cancer
Trial description: This study will monitor the safety of novel immunotherapy combinations in participants with Programmed death ligand-1 (PD L-1) high (Tumor cells [TC]/ Tumor proportion score [TPS] >= 50%), previously untreated, unresectable, locally advanced or metastatic non-small cell lung cancer (NSCLC). Drug name mentioned as Belrestotug, GSK4428859A, and EOS884448 are all interchangeable for the same compound. In the rest of the document, the drug will be referred to as Belrestotug.
