Abstract
Introduction: This study aimed to evaluate the efficacy and safety of sarecycline in Chinese patients with moderate-to-severe acne vulgaris (AV).
Methods: The 12-week (W) randomized, multicenter, double-blind (DB), placebo-controlled phase 3 trial was conducted from 29 October 2021 to 14 October 2022 at 34 centers in China, with a 36W open-label follow-up (OLFU) until 23 June 2023 for patients who responded to treatment during the DB period. Patients aged 9-45 years with AV were randomized (2:1) to sarecycline (approximately 1.5 mg/kg/day) or placebo for 12W. Treatment responders received sarecycline for an additional 12W if acne recurred during the OLFU. Endpoints were absolute change from baseline (CFB) and percent CFB (%CFB) to W3, W6, W9 and W12 in facial inflammatory lesion counts.
Results: Three hundred ninety-one patients comprised the intent-to-treat analysis set (mean age: 21.9 years; 58.6% female). Sarecycline-treated patients had a statistically significantly greater reduction in the mean (standard error [SE]) absolute and %CFB to W12 in facial inflammatory lesion counts than placebo-treated patients: - 24.3 (0.7) vs. - 15.4 (1.0) (p < 0.001) and - 73.2% vs. - 46.0% (p < 0.001), respectively, with improvements observed as early as W3. Sarecycline was safe and well tolerated through W12. Incidence of treatment-emergent adverse events (TEAEs) with sarecycline (48.3%) was similar to that of placebo (49.6%). Most TEAEs were mild (87.3%), and few patients reported TEAEs that led to discontinuation of sarecycline (1.9%) or placebo (2.3%). Notably, patients whose acne recurred in the OLFU (23/45 [51.1%]) responded well to a second 12W course of sarecycline with a mean (standard deviation [SD]) reduction of - 23.1 (8.9) in the absolute CFB to the first visit after treatment reinitiation in facial inflammatory lesion counts.
Conclusions: Sarecycline was effective and had an acceptable safety profile in treating moderate-to-severe AV in Chinese patients, supporting its value for treating AV in this population.

期刊介绍:
Dermatology and Therapy is an international, open access, peer-reviewed, rapid publication journal (peer review in 2 weeks, published 3–4 weeks from acceptance). The journal is dedicated to the publication of high-quality clinical (all phases), observational, real-world, and health outcomes research around the discovery, development, and use of dermatological therapies. Studies relating to diagnosis, pharmacoeconomics, public health and epidemiology, quality of life, and patient care, management, and education are also encouraged.
Areas of focus include, but are not limited to all clinical aspects of dermatology, such as skin pharmacology; skin development and aging; prevention, diagnosis, and management of skin disorders and melanomas; research into dermal structures and pathology; and all areas of aesthetic dermatology, including skin maintenance, dermatological surgery, and lasers.
The journal is of interest to a broad audience of pharmaceutical and healthcare professionals and publishes original research, reviews, case reports/case series, trial protocols, and short communications. Dermatology and Therapy will consider all scientifically sound research be it positive, confirmatory or negative data. Submissions are welcomed whether they relate to an International and/or a country-specific audience, something that is crucially important when researchers are trying to target more specific patient populations. This inclusive approach allows the journal to assist in the dissemination of quality research, which may be considered of insufficient interest by other journals. The journal appeals to a global audience and receives submissions from all over the world.
