Study Details

Brief summary:

This study is testing a new medicine called PF-08634404 and how it works in adults with advanced Renal Cell Carcinoma (RCC)- a type of kidney cancer that is either locally advanced (spread to nearby tissues) or metastatic (spread to other parts of the body). The study will look at the safety of the study medicine, when given alone or with other anticancer medicines, and how this type of cancer responds to them.

To join the study, participants must be adults; with locally advanced or metastatic RCC; who have not received treatment for their advanced kidney cancer.

Participants will receive study medicine either alone or with other anticancer medicines. The medicine will be given through intravenous (IV) infusions, which means it will be injected directly into a vein. All treatments will take place at clinical study sites, where trained medical staff will take care of participants during and after each visit.
