Sorafenib Tosylate in Treating Patients With Progressive Metastatic Neuroendocrine Tumors

• Status: Completed
• Trial end date: 2013-04-01
• Target enrollment: 0
• Participant gender: All

Summary

This phase II trial is studying how well sorafenib tosylate works in treating patients with progressive metastatic neuroendocrine tumors. Sorafenib tosylate 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)
• Treatments: Niacinamide; Sorafenib
