Brief summary: The primary objective of this study is to compare the efficacy, safety, and tolerability of IDP-120 Gel to IDP-120 Component A, IDP-120 Component B, and IDP-120 Vehicle Gel in subjects with moderate to severe acne vulgaris.

Detailed description: This is a multi-center, randomized, double-blind, vehicle-controlled, 12-week study designed to assess the safety, tolerability, and efficacy of IDP-120 Gel in comparison with IDP-120 Component A, IDP-120 Component B, and IDP-120 Vehicle Gel at Weeks 2, 4, 8, and 12 in subjects with moderate to severe acne. IDP-120 is a gel for the topical treatment of acne.
