Официальное название

A Phase Ic/II Clinical Study to Explore the Safety, Tolerability, Efficacy, and Pharmacokinetics of Multiple Oral Doses of LT-002-158 Tablets in Chinese Adult Patients With Hidradenitis Suppurativa

Обзор

This study is a Phase Ic/II clinical trial conducted in Chinese patients with moderate-to-severe hidradenitis suppurativa (HS), aiming to evaluate the safety and efficacy of LT-002-158 tablets in the treatment of moderate-to-severe HS. The study consists of two parts. The Phase Ic portion employs an open-label, single-arm design to primarily investigate the safety and tolerability of LT-002-158 tablets in patients with moderate-to-severe HS. The Phase II study adopts a randomized, double-blind, placebo-controlled, parallel-group design, with an open-label, single-arm extension phase, to primarily assess the therapeutic efficacy of LT-002-158 tablets in patients with moderate-to-severe HS.
