The Company plans to present trial data along with a proposed Phase 3 development program in an End of Phase 2 meeting with the FDA before the end of this year
BRIDGEWATER, N.J., June 02, 2020 (GLOBE NEWSWIRE) — Menlo Therapeutics Inc. (Nasdaq: MNLO) (“Menlo” or the “Company”), a specialty pharmaceutical company focused on developing and commercializing proprietary therapies to address unmet needs in dermatology, today announced positive results from a Phase 2 clinical trial evaluating the preliminary safety and efficacy of FCD105 (3% minocycline / 0.3% adapalene foam), the first ever topical minocycline-based combination product, for the treatment of moderate-to-severe acne vulgaris. Study FX2016-40 enrolled 447 patients in the United States who were randomized to either FCD105 foam, 3% minocycline foam, 0.3% adapalene foam, or vehicle foam. The Company has begun preparations to conduct an End of Phase 2 meeting with the FDA before the end of this year.
FCD105 showed a highly statistically significant improvement compared to vehicle for the endpoints of (1) Investigator’s Global Assessment (IGA) treatment success (IGA score “0” or “1” and at least a two-grade improvement from baseline) and (2) absolute change from baseline in mean inflammatory counts at Week 12. The proportion of patients achieving IGA treatment success in the FCD105 treatment group was 35.9% compared to 15.7% of patients in the vehicle treatment group (p=0.0003). Absolute reduction in inflammatory lesion counts at Week 12 was -19.4 (-64.1%) for the FCD105 treatment group compared to -15.58 (-50.9%) for the vehicle treatment group (p=0.0020).
The trial was not originally powered to demonstrate a statistical difference between FCD105 and either 3% minocycline foam or 0.3% adapalene foam treatments; however, the majority of these comparisons did show a statistically significant improvement of FCD105 at Week 12. Numerical improvement was observed for FCD105 on all efficacy endpoints for these comparisons at Week 12.
Absolute reduction in non-inflammatory lesion counts at Week 12 was also assessed with a mean lesion count reduction of -24.94 (-51.0%) for the FCD105 treatment group compared to -22.87 (-45.9%) for the vehicle treatment group. Although numerical improvement was shown, this was not statistically significant, which has been attributed to outlier results affecting both FCD105 and vehicle treatment groups. Conversely, absolute reduction in non-inflammatory lesion counts at Week 12 for FCD105 did show a statistically significant improvement compared to each of (1) 3% minocycline foam and (2) 0.3% adapalene foam.
The most commonly reported treatment-emergent adverse event in the trial was upper respiratory tract infection (4.9% in the vehicle treatment group) with dry skin being the most commonly reported cutaneous adverse event (3.6% in the 0.3% adapalene treatment group). The majority of adverse events were assessed as mild in severity. There were no serious adverse events.
FCD105 was comparably tolerated to vehicle in all local skin tolerability assessments with 93% or greater of severity scores being assessed as “none” or “mild” for burning/stinging, itching, dryness, scaling, erythema and hyperpigmentation.
“We are pleased with the results of this study. The data suggests FCD105 has the potential to be a best-in-class treatment for patients with acne and could provide an important new treatment option for this challenging condition,” said Dr. Iain Stuart, Chief Scientific Officer of Menlo. “We look forward to engaging with the FDA on these data and our plans for the Phase 3 program.”
About Study FX2016-40
Study FX2016-40 is a prospective, randomized, double-blind, vehicle-controlled Phase 2 trial that enrolled patients aged 12 years and older with a clinical diagnosis of moderate-to-severe acne vulgaris. Patients were randomized to one of four treatment arms: FCD105 foam, 3% minocycline foam, 0.3% adapalene foam, or vehicle foam and self-applied their assigned treatment once daily for 12 weeks. The primary efficacy endpoints were: (1) the proportion of patients achieving treatment success at Week 12 based on an Investigator’s Global Assessment (success is defined as a score of 0 “clear” or 1 “minimal” and at least a two-grade 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 evaluations include reported adverse events, local skin tolerability assessments, physical examinations and vital signs.
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.
FCD105 is Menlo’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 United States, with the latter available in combination and as monotherapy. Pending a successful development program, the FCD105 new drug application is intended to be filed under the FDA’s 505(b)(2) regulatory pathway.
Menlo Therapeutics Inc. recently combined with Foamix Pharmaceuticals Ltd. to form a different type of biopharmaceutical company working to solve some of today’s most difficult therapeutic challenges in dermatology and beyond.
With expertise in topical medicine innovation as a springboard, the Company is working to develop and commercialize a variety of solutions using its proprietary Molecule Stabilizing Technology (MST™), and has received FDA approval for AMZEEQ® (minocycline) topical foam, 4%, the world’s first topical minocycline, and now also for ZILXI™ (minocycline) topical foam, 1.5%, the first minocycline product of any kind to be approved by the FDA for use in rosacea.
