2022年2月28日,嘉兴特科罗生物科技有限公司(以下简称“特科罗”)宣布,其针对雄激素性脱发(AGA)患者的外用药TDM-105795酊剂于上周2月23日在美国完成临床一期1b(MAD)试验第一个剂量组全部病人入组,并开始给患者用药。特科罗是专注皮肤新药研发的生物制药公司。

我们预期目前临床的研究结果能够指导我们选择适合的配方浓度剂量,以进行后续临床二期的研究,即验证雄激素性脱发治疗的概念(PoC)。患者在用药治疗几个月内,我们预计将可以观察到TDM-105795在临床前测试中证明的促进毛发生长的效果。
治疗雄激素性脱发的TDM-105795是特科罗公司治疗各种皮肤病管道产品中的第一个重磅临床药物。公司正努力将治疗湿疹/特应性皮炎的第二个管道产品在今年年中引入临床研究。

This second clinical trial in the program is a 28-day multiple dose escalation study entitled, “A Randomized, Double-Blind, Vehicle-Controlled, Parallel Group, Multi-Dose Escalation Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of TDM-105795 in Healthy Male Subjects with Androgenetic Alopecia”.

雄激素性脱发(AGA),也称为男性或女性型秃发,是影响男性和女性的最常见脱发,男性发病率更高。超过一半的成年男性患有AGA,50岁及以上的男性中,这一比例可升到80%以上。男性AGA的特点是发际线后退,头顶和头前部秃顶。女性AGA通常表现为头顶头发变稀疏。导致脱发的病因还很不清楚,脱发是退行性疾病,遗传、心理、精神、内分泌和代谢等因素都可能引起脱发。AGA的发病机制与毛囊细胞中雄激素受体的过度激活有关,使静止的毛囊无法重新进入生长期,导致毛囊萎缩。
