The study will involve two treatment groups. Eligible patients will be randomized to receive either FXFM244 - 1%, FXFM244 - 4% , in a blinded fashion. Patients will be treated twice daily for 7 days. Following the screening period and baseline visit, study subjects will return at days 3, 7 and 14. At each visit, patients will be evaluated via lesion count, global assessment tolerability and safety.
