Sol-Gel Technologies Initiates Pivotal Phase III Clinical Program of TWIN for the Treatment of Acne Vulgaris
First subject dosed in pivotal Phase III program evaluating TWIN in subjects with moderate-to-severe acne vulgaris
Two Phase III trials expected to enroll a total of approximately 840 subjects
Top-line data anticipated by the end of 2019
“Initiating the Phase III program for TWIN is a transformational milestone for
The program consists of two randomized, double-blind, vehicle-controlled Phase III clinical trials. Each pivotal trial is planned to enroll approximately 420 subjects aged 9 and above at a 2:1 ratio, with a power of 99%. The objective of the study is to evaluate the efficacy and safety of TWIN, a topical cream containing encapsulated tretinoin and encapsulated benzoyl peroxide, compared to vehicle when applied once daily for 12 weeks in patients with moderate-to-severe acne vulgaris.
The pivotal TWIN clinical program is being executed under a Special Protocol Assessment (SPA) agreement with the
Based on the FDA’s feedback provided in the minutes of the End-of-Phase II meeting and the associated SPA agreement, key elements of the Phase III program are:
- Only the TWIN and vehicle cream (placebo) arms are required for the Phase III clinical trials, as the requirements of the combination rule act were satisfied in our Phase II trial.
- No pediatric clinical studies are required to support our future marketing application.
- No long-term safety study will be required to support our marketing application, as long as we demonstrate that the systemic exposure of our product candidate is comparable to the reference-listed drug.
TWIN is a novel non-antibiotic topical cream for the treatment of acne vulgaris that is designed to be tolerable and highly effective. TWIN is the first acne treatment that contains a fixed-dose combination of benzoyl peroxide and tretinoin, which are separately encapsulated in silica using our proprietary technology. Tretinoin and benzoyl peroxide are widely believed to be effective as a combination treatment for acne. The silica microcapsule protects tretinoin from oxidative decomposition by benzoyl peroxide, thereby enhancing the stability and shelf-life of the product. The silica shell also creates a barrier between the drug substances and the skin and as a result is expected to reduce irritation typically associated with topical application of benzoyl peroxide and tretinoin, thereby increasing the tolerability of TWIN on acne-affected skin.
