What You Need to Know Before You Apply

What is the purpose of this trial?

This study is being done to learn more about a new medicine called PF-08634404. It is for adults with a type of bladder cancer called locally advanced or metastatic urothelial cancer (LA/mUC), meaning the cancer has spread to nearby tissues or other parts of the body.

The purpose of the study is to see if PF-08634404 is safe, how well it works, how it moves through the body, and how it affects the cancer. The study will also look at how the medicine may change certain markers in the body that are linked to cancer.

To join the study, participants must:

* Be adults (18 years or older) and

* Have locally advanced or metastatic urothelial cancer,

The study has two groups:

* Cohort A: People who have already received treatment for their cancer will get the study medicine ( PF-08634404) alone.

* Cohort B: People who have not had treatment before will get the study medicine along with another cancer medicine called enfortumab vedotin.

Everyone in the study will get the study medicine through a vein (IV infusion) with or without enfortumab vedotin. Treatment will continue as long as it helps and side effects are manageable.

Before starting, participants will go through a screening period to check if they are eligible. During the study, they will have regular visits for treatment, health checks, and tests to see how the cancer is responding. Scans will be done regularly to monitor the cancer.

If the cancer gets worse but the treatment is still helping and side effects are manageable, participants may be allowed to continue treatment with their doctor's and the sponsor's agreement.
