Clinical trials

The goal of this clinical trial is to evaluate the rapid onset characteristics of TLL-018 in moderate-to-severe CSU with inadequate response to second-generation H1 antihistamines. The main objectives are: To evaluate the rapid onset characteristics of TLL-018 in participants with moderate-to-severe chronic spontaneous urticaria. To evaluate the safety profile of TLL-018 in participants with moderate-to-severe chronic spontaneous urticaria. To evaluate the pharmacokinetic (PK) profile of TLL-018 in participants with moderate-to-severe chronic spontaneous urticaria. Participants will be randomly allocated at a 1:1:1 ratio to receive TLL-018 10 mg, TLL-018 20 mg, or placebo orally after meals.

The goal of this clinical trial is to learn if different doses of TLL-018 works to treat in moderate-to-severe chronic spontaneous urticaria (CSU) participants . It will also learn about the safety of TLL-018. The main questions it aims to answer are: Which is the best regimen of TLL-018 administration in reducing or eliminating symptoms (hives, itch, and/or angioedema) ? What medical problems do participants have when taking TLL-018? Researchers will compare different doses of TLL-018, and placebo (a look-alike substance that contains no drug). Participants will: Take TLL-018 or a placebo every day for 12 weeks Visit the clinic once every 4 weeks for checkups and tests Keep a diary of their symptoms

This is a randomized, double-blind, placebo-controlled parallel-group Phase II study. The study aims to evaluate the efficacy and safety of TLL-018 in adult patients with moderate to severe active rheumatoid arthritis who have inadequate response or intolerance to conventional synthetic disease-modifying antirheumatic drugs (csDMARDs).

This study is a randomized, double-blind, placebo-controlled, multicenter Phase Ib/II clinical study designed to evaluate the efficacy, safety, and PK characteristics of HL-300 ointment with different concentration regimens for mild-to-moderate AD.

The primary objective of the study is to evaluate the long-term safety, tolerability, and efficacy of TLL-018 in patients with rheumatoid arthritis (RA) who have completed a preceding randomized controlled trial with TLL-018.
