Foamix Announces Enrollment of First Patient in Phase 2 Acne Clinical Trial for FCD105 Minocycline 3% and Adapalene 0.3% Combination Foam

REHOVOT, Israel and BRIDGEWATER, N.J., Sept. 19, 2019 (GLOBE NEWSWIRE) — Foamix Pharmaceuticals Ltd. (NASDAQ:FOMX), today announced that the first patient has been enrolled in its Phase 2 clinical trial to evaluate the efficacy and safety of its topical combination foam, comprised of minocycline 3% and adapalene 0.3%, FCD105 for the treatment of moderate-to-severe acne vulgaris.

“FCD105 combines minocycline and adapalene, which are two leading agents for treating inflammatory and non-inflammatory comedonal acne lesions, respectively, in a convenient, foam-based product. We currently expect topline data from this study in mid-2020,” said David Domzalski, CEO of Foamix. “The initiation of this Phase 2 clinical trial for FCD105 is an important milestone for Foamix, as this would be our first follow-on product behind our lead product candidates, FMX101 for moderate to severe acne vulgaris, and FMX103, for the treatment of moderate-to-severe papulopustular rosacea.”

Study Design

The Phase 2 clinical trial is expected to enroll approximately 400 patients, aged 12 years and older, with moderate-to-severe acne vulgaris. This prospective, randomized, double-blind, vehicle-controlled trial will be conducted at multiple sites throughout the United States. Patients will be randomized to one of four treatment arms: FCD105 foam, 0.3% adapalene foam, 3% minocycline foam or vehicle foam and will self-apply their assigned treatment once daily for 12 weeks. The study design follows current regulatory standards in evaluating the safety and efficacy of combination products of this type.

The primary endpoints are: 1) the proportion of patients achieving success at week 12 based on an Investigator’s Global Assessment (success is defined as a score of “clear” or “minimal” and at least a 2 category improvement from baseline), 2) the mean change from baseline in inflammatory lesion counts in each treatment group at week 12, and 3) the mean change from baseline in non-inflammatory lesion counts in each treatment group at week 12.  Safety evaluation will include reported adverse events, skin tolerability assessments, physical examinations and vital signs.

About FCD105

FCD105 is Foamix’s proprietary 3% minocycline, 0.3% adapalene combination foam formulation intended for the treatment of moderate-to-severe acne vulgaris. FCD105 combines the bacteriostatic and anti-inflammatory properties of minocycline with the third-generation retinoid, adapalene, which acts in regulating the differentiation of follicular epithelial cells. Oral minocycline and topical adapalene products are approved for use in the treatment of acne vulgaris in the USA, with the latter available in combination and as monotherapy. Foamix’s FMX101 (minocycline 4% foam) New Drug Application (NDA) is undergoing review by FDA under the 505(b)(2) regulatory pathway with a PFUFA action date of 20 October 2019. Pending a successful development program, the FCD105 NDA is intended to be filed under the same regulatory pathway.

About Acne Vulgaris

Acne is a chronic, inflammatory skin condition that affects the skin’s oil glands and hair follicles. It is characterized by both inflammatory lesions (papules and pustules) and non-inflammatory lesions (open and closed comedones) affecting primarily the face and other areas of the body. Acne affects approximately 40 to 50 million people in the U.S. alone, of whom approximately 10 million have moderate-to-severe disease that significantly impacts self-esteem and quality of life. For most people, acne diminishes over time and tends to disappear or decrease, by age 25. However, some individuals, particularly women, can experience acne much later in life.
