NCT ID: NCT07300189

Last Updated: 2025-12-23

Basic Information

• Recruitment Status: RECRUITING
• Clinical Phase: PHASE1
• Total Enrollment: 288 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2025-11-06
• Study Completion Date: 2026-11-01

Brief Summary

This phase 1 study is designed to evaluate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of TLC-1180 after single- and multiple-ascending doses in healthy subjects.

Detailed Description

The primary objectives are to assess the safety, tolerability, and plasma PK of TLC-1180 in healthy subjects. The exploratory objective is to evaluate the PD of TLC-1180 in healthy subjects. This study is comprised of four parts: Part A (single-ascending dose), Part B (multiple-ascending dose), optional Part C (adaptive single- and/or multiple-ascending dose), and Part D (relative bioavailability of a tablet formulation of TLC-1180). Up to 72, 100, 100, and 8 healthy subjects will be recruited in Parts A, B, C, and D, respectively. The effect of food on TLC-1180 PK will also be evaluated in this study.

• Subjects who have any serious or active medical or psychiatric illness (including depression) that, in the opinion of the investigator, would interfere with the subject's treatment, assessment, or compliance with the protocol
• Subjects who have received any investigational compound within 30 days or 5 half-lives, whichever is longer, prior to study drug dosing
• Current alcohol abuse that is judged by the investigator to potentially interfere with the subject's compliance or safety
• Current substance abuse that is judged by the investigator to potentially interfere with the subject's compliance or safety
• A positive test result for human immunodeficiency virus (HIV-1) antibody, hepatitis B (HBV) surface antigen, or hepatitis C (HCV) antibody
