Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The safety and efficacy of once daily application of IDP 126 Gel will be compared to Epiduo® Forte and IDP-126 Vehicle Gel.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a multicenter, randomized, double-blind, vehicle-controlled, 12-week study designed to assess the safety, tolerability, and efficacy of IDP-126 Gel in comparison with Epiduo® Forte gel and IDP-126 Vehicle Gel at Weeks 2, 4, 8, and 12. To be eligible for the study, subjects must be at least 12 years of age and have a clinical diagnosis of moderate to severe acne (defined as an Evaluator's Global Severity Score \[EGSS\] of 3 or 4), presenting with 30-100 inflammatory facial lesions (papules, pustules, and nodules), 35-150 non-inflammatory facial lesions (open and closed comedones), and ≤ 2 facial nodules.

* Subject must have an EGSS of 3 (moderate) or 4 (severe) at the baseline visit.
* Subjects with a facial acne inflammatory lesion (papules, pustules, and nodules) count no less than 30, but no more than 100.
* Subjects with a facial acne non-inflammatory lesion (open and closed comedones) count no less than 35, but no more than 150.
* Subjects with 2 or fewer facial nodules.

Exclusion Criteria

* Any dermatological conditions on the face that could interfere with clinical evaluations such as acne conglobata, acne fulminans, secondary acne, perioral dermatitis, clinically significant rosacea, gram negative folliculitis, dermatitis, eczema.
* Any underlying disease(s) or some other dermatological condition of the face that requires the use of interfering topical or systemic therapy or makes evaluations and lesion count inconclusive.
* Subjects with more than 2 facial nodules.
* Female subjects who are pregnant, nursing mothers, planning a pregnancy during the course of the study, or become pregnant during the study.
* Use of estrogens (eg, Depogen, Depo-Testadiol, Gynogen, Valergen, etc) for less than 12 weeks immediately preceding study entry; subjects treated with estrogens 12 or more consecutive weeks immediately prior to study entry need not be excluded unless the subject expects to change dose, drug or discontinue estrogen use during the study.
* Treatment of any type of cancer within the last 6 months, with the exception of complete surgical excision of skin cancer outside the treatment area.
* Subjects who have not undergone specified washout period(s) for topical preparations/physical treatments used on the face or subjects who require the concurrent use in the treatment area.
* Subjects who have not undergone specified washout period(s) for systemic medications or subjects who require the concurrent use of systemic medications.
