A Study to Evaluate the Reduction in Sebum (Skin Oil) Induced by Clascoterone Cream 1% in Acne Patients

Completed · Phase 4

Conditions studied: Acne Vulgaris

In brief

The etiology of acne is heavily dependent on the production of sebum by the sebaceous glands that results in the growth of the bacteria c. acnes. If no sebum is present, there is no nutritional source for the c. acnes, the bacteria die, and acne resolves. An FDA approved acne medication consisting of clascoterone cream 1% is believed to effectively treat acne due to a decrease in sebum production. This mechanism of action has been postulated based on efficacy observed in the phase III trials that lead to its approval. This research aims to demonstrate the effect of clascoterone cream 1% in sebum reduction.
