Detaillierte Beschreibung
PRIMARY OBJECTIVE:
I. To determine sulindac and metabolite levels in healthy participants with atypical nevi and benign nevus at increased risk for melanoma treated with sulindac versus placebo.
SECONDARY OBJECTIVES:
I. To assess the effects of sulindac on apoptosis in atypical nevi of these participants.
II. To assess the effects of sulindac on VEGF expression in atypical nevi of these participants.
III. To assess sulindac and metabolite levels in plasma and its association with drug levels in the target tissue.
OUTLINE: This is a multicenter study. Participants are randomized to 1 of 2 treatment arms.
ARM I: Participants receive oral sulindac twice daily.
ARM II: Participants receive oral placebo twice daily.
In both arms, treatment continues for 8 weeks in the absence of unacceptable toxicity.
Blood and tissue samples are collected at baseline and/or after completion of study therapy and analyzed for sulindac and metabolite levels via high performance liquid chromatography tandem mass spectrometry; the detection of apoptotic cells via TUNEL assay; and VEGF expression via immunohistochemistry assays.
After completion of study therapy, participants are followed for 2 weeks.
