ZILXI is the First FDA Approved Minocycline Product for the Treatment of Inflammatory Lesions of Rosacea in Adults
ZILXI demonstrated a favorable safety and tolerability profile for up to 52 weeks of treatment
Efficacy of ZILXI continued to develop for an additional 40 weeks of treatment after an initial treatment period of 12 weeks
BRIDGEWATER, N.J., Dec. 01, 2020 (GLOBE NEWSWIRE) — VYNE Therapeutics Inc. (Nasdaq: VYNE) (“VYNE” or the “Company”) announced today the peer reviewed publication of long-term safety and efficacy data for ZILXI™ (minocycline) topical foam, 1.5% in the Journal of Clinical and Aesthetic Dermatology (JCAD). Study FX2016-13 evaluated the safety and efficacy of ZILXI for up to 40 weeks of open-label treatment immediately following an initial 12-week double-blind treatment. This study was conducted by VYNE to support the New Drug Application (NDA) of ZILXI which was approved by the U.S. Food and Drug Administration (FDA) for the treatment of inflammatory lesions of rosacea in adults in May of this year.
“Following the commercial launch of ZILXI in October, we are pleased that JCAD has accepted these long-term safety and efficacy data for publication,” said David Domzalski, CEO of VYNE. “We hope that ZILXI’s safety profile for long term treatment coupled with enduring efficacy will provide patients living with rosacea an attractive new option for lasting control of their disease.”
Highlights from the Long-Term Safety & Efficacy in Study FX2016-13:
Study FX2016-13 included a total of 504 patients in the all-treated population, all of whom had completed 12 weeks of ZILXI or vehicle treatment in one of two preceding double-blind phase 3 studies (Studies FX2016-11 or FX2016-12). Patients continued for up to an additional 40 weeks of open-label treatment with ZILXI.
410 patients completed participation in the study of which 332 patients had received a total of 52 weeks of ZILXI therapy which was in excess of the subject sample size requirements specified in the regulatory guidance for this type of safety evaluation (ICH E1A, 1995). 96.1% of patients participating in study FX2016-13 received a minimum of 26 weeks of ZILXI therapy. Key findings from the study are as follows:
- Non-dermal adverse events were comparable in type and frequency with those reported during the preceding 12-week double-blind studies. The most frequently reported treatment-emergent adverse event in this study was upper respiratory tract infection (common cold) (14 subjects). A total of 5 patients discontinued the study over the course of 40 weeks of treatment due to an adverse event and no serious drug-related adverse events were reported.
- In the assessment of facial dermal tolerability at Week 52, the majority of subjects (>57%) had no signs of burning/stinging, flushing/blushing, dryness/xerosis, itching, peeling/desquamation, or post-inflammatory hyperpigmentation. All facial local tolerability assessments made at Week 52 improved relative to assessments made at the study baseline of the preceding double-blind studies. In this regard, the percentage of patients with clear and almost clear erythema at study baseline of the preceding double-blind studies improved from 4.0% to 59.3% by the end of the open-label study.
- Long-term treatment with ZILXI was associated with a progressive decrease in inflammatory lesions and a parallel increase in the proportion of subjects achieving IGA treatment success. The overall mean percent change (reduction) from study baseline of the preceding double-blind studies when assessed at Week 52 was 82.3%. Equally, the proportion of subjects achieving Investigator Global Assessment (IGA) treatment success (IGA score of 0 “clear” or 1 “almost clear”) at week 52 was 79.8%.
- Subject satisfaction with ZILXI treatment continued to increase when re-assessed at Week 52 relative to Week 12 assessments made in the preceding double-blind studies. At Week 52, the majority of subjects (82.4%) reported being overall “satisfied” or “very satisfied” with ZILXI in treating their rosacea. The majority of subjects (83.2%) were also satisfied or very satisfied with how ZILXI compared with other products, as well as with its ease of use (92.9%). Most subjects (83.2%) reported being “likely” or “very likely” to recommend ZILXI to a friend.
“We are pleased that our comprehensive long-term safety and efficacy evaluation of ZILXI has been published in JCAD. ZILXI is well tolerated, with an acceptable safety profile and impressive long-term efficacy which are important factors in the treatment of chronic, relapsing dermatological conditions such as rosacea,” said Dr. Iain Stuart, Chief Scientific Officer of VYNE.

Rosacea is a diverse skin condition that most commonly presents with symptoms such as deep facial redness, spider veins (telangiectasia) and acne-like inflammatory lesions (papules and pustules). It can create psychosocial burdens, such as embarrassment, anxiety and low self-esteem that can adversely affect quality of life.1 Rosacea is most frequently seen in adults between 30 and 50 years of age. It affects more than 16 million people in the United States; up to 28% of these sufferers have rosacea with inflammatory lesions.2
