About

This phase 1 study is designed to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of TLC-2716 after single- and multiple-ascending doses in healthy subjects.

Full description

This study is a randomized, placebo-controlled, sponsor-unblinded, and comprised of three parts: Part A (single-ascending dose), Part B (multiple-ascending dose), and Part C (adaptive single- and/or multiple-ascending dose).

Enrollment: 100 patients

Sex: All

Ages: 18 to 55 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Non-smoking, healthy male or female subject between 18 and 55 years of age, inclusive
• Body mass index from 19 to 35 kg/m2, inclusive
• Estimated glomerular filtration rate ≥ 80 mL/min
• Normal liver biochemistry tests
• Screening laboratory evaluations (hematology, chemistry, and urinalysis) must fall within the normal range of the local laboratory's reference ranges unless the results have been determined by the investigator to have no clinical significance
• Subject must have either a normal 12-lead electrocardiogram (ECG) or one with abnormalities that are considered clinically insignificant by the investigator
• Females of childbearing potential must have a negative pregnancy test at Screening and clinic admission
• Male subjects and female subjects of childbearing potential who engage in heterosexual intercourse must agree to use protocol-specified method(s) of contraception
• Must, in the opinion of the investigator, be in good health based upon medical history and physical examination, including vital signs

Exclusion criteria

• Pregnant or lactating subjects
• Subjects with triglycerides ≥ 500 mg/dL
• Subjects with low-density lipoprotein ≥ 190 mg/dL
• 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
• Subjects who have taken any prescription medications or over-the-counter medications, including herbal products, within 28 days prior to start of study drug dosing, with the exception of vitamins, acetaminophen (paracetamol), ibuprofen, and/or hormonal contraceptive medications
• 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)
• Severe peptic ulcer disease, gastroesophageal reflux disease, or other gastric acid hypersecretory conditions
• History of medical or surgical treatment that permanently alters intestinal absorption (e.g., gastric or intestinal surgery)
• Subjects who have received vaccination for COVID-19 within 14 days of Admission

Note: Other protocol defined Inclusion/Exclusion criteria may apply.

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Sequential Assignment

Masking: Double Blind

---

100 participants in 3 patient groups

Part A: Single Ascending Dose (SAD)

Experimental group

Description:

Part A will be comprised of up to 50 participants over 5 cohorts of 10. Each participant will receive a single oral dose of TLC-2716 or placebo at different dose levels (1 cohort per dose level).

Treatment:

Other: Placebo

Drug: TLC-2716

Part B: Multiple Ascending Dose (MAD)

Experimental group

Description:

Part B will be comprised of up to 50 healthy participants over 5 cohorts of 10. Each participant will receive 14 oral doses of TLC-2716 or placebo over 14 days (given once daily) at different dose levels (1 cohort per dose level).

Treatment:

Other: Placebo

Drug: TLC-2716

Part C: Adaptive SAD and/or MAD

Experimental group

Description:

Part C is an adaptive style where the dosing level is a single- or multiple-ascending dose design. Based on safety and pharmacokinetic data from Parts A and B, doses for Part C will be chosen. Part C will be comprised of up to 50 participants over 5 cohorts of 10. Each participant will receive an oral dose of TLC-2716 or placebo at different dose levels (1 cohort per dose level).

Treatment:

Other: Placebo

Drug: TLC-2716
