(SGN22E-002) A phase 1b dose-escalation and dose-expansion study of enfortumab vedotin (ASG-22CE) in combination with pembrolizumab and/or chemotherapy for treatment of patients with locally advanced or metastatic urothelial cancer
This study will test an experimental drug (enfortumab vedotin) with different combinations of pembrolizumab and/or chemotherapy. Pembrolizumab is an immune checkpoint inhibitor (CPI) that is used to treat patients with cancer of the urinary system (urothelial cancer). This type of cancer includes cancer of the bladder, renal pelvis, ureter or urethra that has spread to nearby tissues or to other areas of the body. This study will have different parts to look at the side effects of (1) enfortumab vedotin with pembrolizumab, (2) enfortumab vedotin with chemotherapy, and (3) enfortumab vedotin with pembrolizumab and chemotherapy. A side effect is a response to a drug that is not part of the treatment effect. This study will also test if the cancer shrinks with the different treatment combinations.
