Topical Myristyl Nicotinate Cream on the Skin of Healthy Volunteers

Phase 1

Completed

Brief Summary: RATIONALE: Chemoprevention is the use of certain drugs to keep cancer from forming. The use of topical myristyl nicotinate cream may stop skin cancer from forming.

PURPOSE: This randomized phase I trial is studying the side effects and best way to give topical myristyl nicotinate cream on the skin of healthy volunteers.

Detailed Description: OBJECTIVES:

* To determine if topical myristyl nicotinate (MN) is a safe, tolerable treatment in healthy volunteers.

* To determine if topically administered MN cream is associated with any significant local or systemic toxicity in normal human subjects in a one-month period.

OUTLINE: Participants are randomized to 1 of 2 treatment arms and serve as their own controls.

* Arm I: Participants apply topical myristyl nicotinate to one forearm and topical placebo to the other forearm once daily for 4 weeks.

* Arm II: Participants receive treatment as in arm I but on opposite forearms. All participants undergo blood collection for chemistry analysis (SMA-20 and CBC) at baseline and at 2 and 4 weeks.
