A Phase 2 Safety and Efficacy Study of UHE-101 Cream in Subjects With Acne Vulgaris

The purpose of this study is to test a topical cream (UHE-101) containing 1.0% of active drug, for 12 weeks, in boys and girls, men and women, in the treatment of facial acne.

Patients who qualify for this study will apply the study cream twice daily (once in the morning and once in the evening) for 12 weeks.

Half of the patients in this study will receive UHE-101 cream and half will receive a vehicle cream that does not include an active drug (i.e., placebo). This is a double-blind study, which means that neither the patient nor the investigator will know which cream the patient is using. The study will last about 12 weeks and will involve 5 clinic visits.
