Pazopanib in Treating Patients With Metastatic Urothelial Cancer

• Status: Completed
• Trial end date: 2013-12-01
• Target enrollment: 0
• Participant gender: All

Summary

This phase II trial is studying the side effects and how well pazopanib works in treating patients with metastatic urothelial cancer. Pazopanib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: National Cancer Institute (NCI)
