A Phase 2, Multicenter, Randomized, Double-Blind, Vehicle-Controlled, Parallel-Group, Clinical Study Comparing the Efficacy and Safety of IDP-126 Gel in the Treatment of Acne Vulgaris

Updated on 7 November 2020


Clinical research study for the treatment of moderate to severe acne vulgaris.


The main purpose of this study is to evaluate the safety, efficacy, and tolerability of a once-daily topical application of IDP-126 Gel in subjects with moderate to severe acne. Subjects must be at least 9 years of age or older and generally healthy. IDP-126 Gel is a fixed dose combination of clindamycin phosphate, benzoyl peroxide (BPO), and adapalene. This study will compare IDP-126 Gel to its active gel components (clindamycin phosphate, BPO, adapalene), as well as its Vehicle Gel. “Vehicle” is a term to describe a gel that looks like the IDP-126 Gel but does not contain any active drug (similar to a placebo). If you decide to be in this research study, you may receive either the IDP-126 Gel, a combination of the individual components of the IDP-126 Gel (clindamycin phosphate, BPO, and/or adapalene), or the IDP-126 Vehicle Gel.

Participation will be approximately 12 weeks (3 months), including 6 in office visits:

You may receive up to $300.00 if you complete the whole study, as a compensation for your time and travel.
