SU5416 Compared to Dexamethasone in Treating Patients With Progressive Prostate Cancer That Has Not Responded to Hormone Therapy

• Status: Completed
• Trial end date: 2006-01-01
• Target enrollment: 0
• Participant gender: Male

Summary

RATIONALE: SU5416 may stop the growth of prostate cancer by stopping blood flow to the tumor. Dexamethasone may be effective in slowing the growth of prostate cancer cells. It is not yet known whether SU5416 or dexamethasone is more effective in treating progressive prostate cancer.

PURPOSE: Randomized phase II trial to compare the effectiveness of SU5416 with that of dexamethasone in treating patients who have progressive prostate cancer that has not responded to hormone therapy.

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

Details

• Lead Sponsor: University of Chicago
• Collaborator: National Cancer Institute (NCI)
• Treatments: BB 1101; Dexamethasone; Dexamethasone 21-phosphate; Dexamethasone acetate; Hormones; Semaxinib
