A Study to Learn About PF-07921585 Alone or With Other Anti-cancer Medicines in People With Cancer

TerminatedPhase 1

Sponsor: Pfizer

Conditions: Non Small Cell Lung Cancer, Bladder Cancer, Renal Cell Carcinoma, Melanoma, Head and Neck Cancer

Interventions: PF-07921585, Sasanlimab

Countries: United States

The purpose of this study is to learn about the safety and effects of the study medicine (called PF-07921585) in people with cancer that has advanced or spread to other parts of the body. This study is seeking participants who have any of the following cancer types: * non-small cell lung cancer * colorectal cancer * bladder cancer * melanoma (a type of skin cancer) * kidney cancer * head and neck cancer Participants will receive the study medicine PF-07921585 alone or in combination with another study medicine called sasanlimab at the study clinic. PF-07921585 will be given as an infusion into a vein or as shots under the skin, once every 3 weeks. Sasanlimab will be given as shots under the skin, also once every 3 weeks. The experiences of participants receiving the study medicine will be studied to help see if the study medicine is safe and effective. Participants may receive study medicine for up to 2 years, depending on how the cancer responds to the study treatment. Participants may continue receiving study medicine after 2 years if there are any benefits from the study treatment. Participants will attend visits once every 3 weeks with the first 9 weeks having more frequent visits, to check the safety of the study treatment.
