Recruiting PHASE4 Locally Advanced Bladder Urothelial Carcinoma

New treatment option for Locally Advanced Bladder Urothelial Carcinoma

Official title Enfortumab Vedotin and Pembrolizumab With Cystectomy and/or Ureterectomy for Locally Advanced or Metastatic Bladder and Upper Urothelial Tract Cancer, CAST-AI Trial

ClinicalTrials.gov ID: NCT06764095

What this study is testing

What is Enfortumab Vedotin?

Enfortumab Vedotin is an investigational medicine, given as an infusion into a vein, being studied as a potential treatment for locally advanced bladder urothelial carcinoma.

Also referred to as AGS 22ME, AGS-22M6E.

Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
This phase IV trial tests the impact of standard of care enfortumab vedotin and pembrolizumab followed by removal of all or part of the bladder (cytoreductive cystectomy) and/or removal of all or part of the tube that carriers urine from the kidneys to the bladder (ureterectomy) on outcomes in patients with bladder and upper urothelial tract that has spread to nearby tissue or lymph nodes (locally advanced) or that has spread from where it first started (primary site) to other places in the body (metastatic). Enfortumab vedotin is a monoclonal antibody, enfortumab, linked to an anticancer drug called vedotin.
  • Phase 4: studies an already-approved treatment
  • Time commitment: about 18 months
