Kintor Pharma Announces Dosing of First Patient in Phase II Clinical Trial of KX-826 for the Treatment of Androgenic Alopecia Female Patients in China

SUZHOU,China,Nov. 12,2021 -- Kintor Pharmaceutical Limited ("Kintor Pharma",HKEX: 9939),a clinical-stage biotechnology company developing innovative small molecule and biological therapeutics,today announced that the company has dosed the first patient in its phase II clinical trial of pyrilutamide ("KX-826") in China for the treatment of androgenetic alopecia (AGA) female patients.

The phase II trial is a randomized,double-blind,placebo-controlled,multi-regional study to evaluate the efficacy and safety of KX-826 for the treatment of AGA in adult females (N=160). The primary endpoint for the trial is the change from baseline in non-vellus target area hair counts (TAHC) at week 24.

Dr. Youzhi Tong,founder,Chairman and CEO of Kintor Pharma,commented,"The population of those who suffer from hair loss has a large number and tends to be younger. By the end of 2020,the number of hair loss in China had exceeded 252 million,among which about 87 million were women. AGA accounts for approximately 90% of patients with hair loss,but there are few therapeutic drugs. So,a safer and more effective drug is in urgent need to address the concerns for the people suffering from hair loss. As a topical AR antagonist with an identified target,KX-826 has showed good efficacy and safety profile in the phase II clinical trial in China for the treatment of AGA male patients. We look forward to further expanding the clinical potential of KX-826 and benefiting more people suffering from hair loss."
