Summary

This is an intent-to-treat, parallel design, multicenter randomized trial and the primary intervention is a double-blind comparison of Imiquimod (IMQ) vs. placebo cream for preventing basal cell carcinoma (BCC) of the skin on the face at one year and over 3 years after therapy. Participants will apply the IMQ or placebo cream to the face daily at bedtime for 12 weeks. This study will recruit 1630 Veterans at high risk of BCC from 17 VA medical centers.

Conditions

Interventions

DRUG

5% Imiquimod cream

Topical 5% Imiquimod cream will be applied once daily to the face in a thin layer for 12 weeks. Three packets of cream will be defined as one dose or application. The cream should be applied to the face prior to normal sleeping hours (it is readily absorbed) and left on the skin for 6-10 hours (i.e. overnight). Rest periods will be allowed if bothersome side effects occur.

DRUG

Placebo Vehicle Control Cream

The placebo vehicle control cream will be a virtually identical cream (to the Imiquimod cream) that contains no Imiquimod. This cream will be applied once daily to the face in a thin layer for 12 weeks. Three packets of cream will be defined as one dose or application. The cream should be applied to the face prior to normal sleeping hours (it is readily absorbed) and left on the skin for 6-10 hours (i.e. overnight). Rest periods will be allowed if bothersome side effects occur.
