SHENZHEN, CHINA, Sept. 28, 2025 (GLOBE NEWSWIRE) -- China Medical System Holdings Limited ("CMS") is pleased to announce that its subsidiaries, Dermavon Holdings Limited ("Dermavon", an innovative pharmaceutical company specialized in skin health which is applying for a separate listing on the Main Board of The Stock Exchange of Hong Kong Limited, please refer to the announcement published by CMS on 22 April 2025 for details) together with its subsidiaries, obtained positive results from the phase 3 clinical trial (the "Trial") of ruxolitinib cream (the "Product") in patients with mild to moderate atopic dermatitis (AD) in China.
The Trial is a randomized, double-blind, placebo-controlled, multi-centre clinical trial, with 192 patients enrolled in total, aiming to evaluate the safety and efficacy of the Product in patients with mild to moderate AD. The leading institution is Shanghai Dermatology Hospital, and the principal investigator is Professor Shi Yuling.
The phase 3 clinical trial of ruxolitinib cream in patients with mild to moderate AD in China met its primary endpoint, demonstrating that a significantly higher proportion of patients treated with ruxolitinib cream achieved IGA (Investigator's Global Assessment) of 0 or 1 with at least two grades of reduction from baseline at week 8, compared with placebo (63.0% vs 9.2%, P<0.001). For the key secondary endpoint, the proportion of patients achieving at least a 75% improvement from baseline in the Eczema Area and Severity Index score (EASI 75) of treatment with ruxolitinib cream was also significantly higher than placebo, at week 8 (78.0% vs 15.4%, P<0.001). In terms of safety, the severity of treatment-emergent adverse events (TEAE) during the treatment period was mostly mild or moderate, with no TEAEs leading to discontinuation of the study drug. Overall, the ruxolitinib cream was safe and well-tolerated.
CMS is actively moving forward the Product's new drug application (NDA) in China.
About AD
AD is a chronic, recurrent and inflammatory dermatologic disease, with the main clinical manifestations of dry skin, chronic eczema-like lesions and obvious itching or pruritus, which may seriously affect the quality of life of patients. It is estimated that there are over 54 million AD patients in China by 2024. Based on SCORAD scores, the proportions of mild, moderate, and severe AD in China in 2024 was 73%, 25%, and 2%, respectively[1]. Topical drugs are the most basic treatment for AD. Traditional topical medications such as topical corticosteroids (TCS) and topical calcineurin inhibitors (TCIs) have clinical pain points with long-term adverse reactions or limited efficacy, therefore novel treatments are urgently needed.
