Pazopanib Hydrochloride in Treating Patients With Metastatic Melanoma That Cannot be Removed by Surgery

• Status: Completed
• Trial end date: 2014-01-16
• Target enrollment: 0
• Participant gender: All

Summary

This phase II trial is studying the side effects of pazopanib hydrochloride and to see how well it works in treating patients with metastatic melanoma that cannot be removed by surgery. Pazopanib hydrochloride 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)
