Kintor Pharma Announces Completion of Subject Enrollment and Dosing in Phase I Clinical Trial of AR-PROTAC(GT20029) in China

SUZHOU,China,Aug. 9,2022 --Kintor Pharmaceutical Limited ("Kintor Pharma",HKEX: 9939),a clinical-stage biotechnology company developing innovative small molecules and biological therapeutics,today announced that the company has completed the enrollment and dosing of 92 subjects for its phase I clinical trial of GT20029 in China for the treatment of androgenetic alopecia (AGA) and acne on August 8,2022.

Developed using Kintor's proprietary Proteolysis Targeting Chimera (PROTAC) platform,GT20029 is the world's first topical androgen receptor (AR) PROTAC compound which entered the clinical stage.

The phase I clinical trial is a randomized,double-blind,placebo-controlled study to evaluate the safety and pharmacokinetics of GT20029 (gel/tincture) following topical administration in single dose and multiple ascending doses in healthy subjects. The leading principal investigators (leading PIs) of the phase I clinical trial are Professor Zhang Jing and AssociateProfessor Wu Xiaojie from Huashan Hospital affiliated to Fudan University. We expect to complete the database lock and preform data analysis in Q4,2022.

In preclinical studies,GT20029 has demonstrated a positive safety profile and was shown to effectively block the AR pathway and physiological function by degrading the AR protein.In addition,by limiting skin penetration,GT20029 inhibits androgenetic effects locally in peripheral skin tissues,avoiding systemic effects and increasing its safety profile.

Dr. Youzhi Tong,founder,Chairman,and CEO of Kintor Pharma,commented,"Both indications of AGA and acne have great unmet clinical needs. As the world's first company to develop a topical AR-PROTAC compound,Kintor is currently conducting phase I clinical trials of GT20029 in China and the United States. We hope to advance a new and effective treatment option for hundreds of millions of patients with AGA and acne worldwide,as well as provide a successful case for the application of PROTAC technology to local drug targets on skin surfaces."
