Evaluation of Topical Application of BMX-010 in Subjects With Acne Vulgaris.

Part A is designed to confirm the optimal formulation, strength, and dosing frequency of the
study drug in patients with Acne. Up to 60 subjects will be enrolled in this part.

Part B is designed to be a randomized, double-blind trial studying the optimal formulation,
strength, and dosing frequency of BMX-010 as determined in Part A, compared to Placebo in
patients with Acne. Up to 150 subjects will be enrolled in this part. In both parts, adult
subjects with Rosacea will be enrolled.
