A Platform Study of Novel Immunotherapy Combinations in Participants With Previously Untreated, Advanced/Metastatic Non-Small-Cell Lung Cancer

Running, not enrolling · Phase 2

Conditions studied: Lung Cancer, Non-Small Cell

In brief

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.
