About

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.

Full 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.

Sex: All

Ages: 18 to 55 years old

Volunteers: Accepts Healthy Volunteers

• Subjects who have been treated with systemic steroids, immunosuppressant therapies, or chemotherapeutic agents within 3 months prior to Screening or expected to receive these agents during the study (e.g., corticosteroids, immunoglobulins, and other immune- or cytokine-based therapies)
• Medical history of serious skin disease in the opinion of the investigator, such as but not limited to rash, food allergy, eczema, psoriasis, or urticaria
• Medical history of drug sensitivity or drug allergy (such as anaphylaxis or hepatoxicity)
• Presence or history of cardiovascular disease, including significant cardiovascular disease (including a history of myocardial infarction based on ECG and/or clinical history), history of cardiac conduction abnormalities (including any history of ventricular tachycardia), congestive heart failure, cardiomyopathy with left ventricular ejection fraction < 40%, a family history of Long QT Syndrome, or unexplained death in an otherwise healthy individual between the ages of 1 and 30 years
• Syncope, palpitations, or unexplained dizziness
• Implanted defibrillator or pacemaker
• Medical history of liver disease, including but not limited to alcoholic liver disease, autoimmune disorders (e.g., primary biliary cholangitis, primary sclerosing cholangitis, autoimmune hepatitis), drug-induced hepatotoxicity, Wilson disease, clinically significant iron overload, or alpha-1-antitrypsin deficiency)
• History of rhabdomyolysis
• Severe peptic ulcer disease, gastroesophageal reflux disease, or other gastric acid hypersecretory conditions
