Sulindac in Preventing Melanoma in Healthy Participants Who Are at Increased Risk of Melanoma

• Status: Completed
• Trial end date: 2011-02-01
• Target enrollment: 0
• Participant gender: All

Summary

This randomized phase II trial is studying how well sulindac works in preventing melanoma in healthy participants who are at increased risk of melanoma. Sulindac may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether sulindac is more effective than a placebo in preventing melanoma in individuals with many moles and abnormal moles.
