A Study to Learn About the Study Medicine Called PF-08046054/SGN-PDL1V Versus Docetaxel in Adult Participants With Previously-Treated Programmed Cell Death Ligand 1 (PD-L1) Positive Non-Small-Cell Lung Cancer (NSCLC)

About this study

The purpose of this study is to understand if PF-08046054 alone works well compared to standard-of-care docetaxel alone in participants with non-small cell lung cancer (NSCLC) with PD-L1 expression greater than or equal to 1% and had cancer progression during or after treatment with PD-L1 or PD-1 inhibitors, platinum-based chemotherapy, and targeted treatment regimen(s) for participants with known actionable genomic alterations (AGAs). Participants in this study must have cancer that has spread through their body or can't be removed with surgery or treated with definitive radiation. Participants will randomly (like a flip of the coin) be assigned to either the PF-08046054 treatment group or the docetaxel treatment group. Participants in the PF-08046054 treatment group will receive an IV infusion (injected directly into the veins) twice during each 21-day cycle. Participants in the docetaxel treatment group will receive an IV infusion once during each 21-day cycle. Study participation may be up to 5 years if the participant's NSCLC is responding to treatment. The study team will see how each participant is doing with the study treatment during regular visits at the clinic.
