Ascletis Announces First Patient Dosed in the Phase II Clinical Trial of FASN Inhibitor ASC40 for Treatment of Moderate to Severe Acne
HANGZHOU and SHAOXING,China,Jan. 13,2022 --Ascletis Pharma Inc. (HKEX: 1672) today announces the dosing of the first patient in the Phase II clinical trial of ASC40 for moderate to severe acne. ASC40 is an oral,selective inhibitor of fatty acid synthase (FASN),a key enzyme which regulates de novo lipogenesis. Human sebum production requires de novo lipogenesis,which is increased in acne and suppressed by the FASN inhibitor ASC40.
The Phase II trial is a randomized,double-blind,placebo-controlled,multicenter clinical trial in China to evaluate the safety and efficacy of ASC40 for the treatment of patients with moderate to severe acne. About 180 patients will be randomized into three active treatment arms or one placebo control arm at the ratio of 1:1:1:1and receive ASC40 (25 mg,50 mg or 75 mg) or matching placebo orally once a day for 12 weeks. The primary outcomes include percentage change of total lesion count at week 12 compared to baseline and ratio of subjects,whose Investigator's Global Assessment (IGA) grades are decreased by ≥2 grades at week 12 compared to baseline.
Acne is the eighth most prevalent disease in the world and affects more than 640 million people globally. The onset of acne often coincides with pubertal hormonal changes,and the condition affects approximately 85% of adolescents and young adults aged 12 to 25 years. However,acne can also persist into or develop during adulthood.
Current first-line treatments for acne include topical creams such as topical retinoids and androgen receptor inhibitor,oral isotretinoin,and antibiotics. A report published by Allied Market Research indicated that the global acne medication market size was US$11.86 billion in 2019,and is projected to reach US$13.35 billion by 2027.
"As a candidate for acne treatment with novel mechanism of action,The dosing of the first patient with ASC40 is the first step for the clinical development in China,and we are looking forward to the trial results," said by Prof. Leihong Xiang,principal investigator of ASC40 Phase II trial for moderate to severe acne vulgaris,chief physician of Dermatological Department,Huashan Hospital,Fudan University,executive deputy director of Institute of Dermatology,deputy director of Dermatology Division of Chinese Medical Doctor Association.
"We have observed that ASC40 inhibited human facial sebum production in the Phase I clinical study. Based on the underlying mechanism of action of ASC40,I am looking forward to the data from this phase II study for the treatment of acne."said Dr. Jinzi J. Wu,Founder,Chairman and CEO of Ascletis.
