A Phase 1, Drug-Drug Interaction Study of TBAJ-876 in Healthy Adults

Detailed Description
This study is a two-part, open-label drug-drug interaction study conducted in one study center in the United States. Two groups are planned, Group 1 and Group 2. Group 2 will be conducted based on the Group 1 results.
Group 1 will assess the induction potential of TBAJ-876 on the sensitive CYP3A4 substrate midazolam (M) and inhibition and induction potential of TBAJ-876 on the sensitive P-glycoprotein substrate Digoxin (D).
Group 2 will only be conducted if the results of Group 1 show that TBAJ-876 is a moderate inducer of either CYP3A4 (midazolam AUC <0.50 when co-administered with TBAJ-876) or P-glycoprotein (digoxin AUC <0.50 when co-administered with TBAJ-876) or a moderate inhibitor of P-glycoprotein (digoxin AUC ≥2.0 when co-administered with TBAJ-876.
This group will quantify the magnitude of inhibition or induction of TBAJ-876 on the antiretroviral regimen TLD, a fixed dose combination of tenofovir disoproxil fumarate (TFD), lamivudine (3TC) and dolutegravir (DTG), a regimen likely to be used in future clinical studies of TBAJ-876 by subjects living with HIV.
Safety will be assessed throughout the study for all subjects. Safety assessments will include physical examinations, vital signs, serial ECGs, adverse events (AEs), clinical and laboratory tests (including hematology, serum chemistry, coagulation, and urinalysis).

Description
Key Inclusion Criteria:
- Is a healthy adult male or female, 18 to 55 years of age (inclusive) at the time of screening.
- Has a body mass index (BMI) ≥18.5 and ≤32.0 (kg/m2) and a body weight of no less than 50.0 kg at the time of screening and check-in.
- Is medically healthy with no clinically significant screening results (e.g., laboratory profiles normal or up to Grade 1 per Division of Microbiology and Infectious Diseases (DMID) Toxicity Tables), as deemed by the Investigator.
- Has not used tobacco- or nicotine-containing products (including smoking cessation products), for a minimum of 6 months before dosing.
- Is willing and able to consume the entire high-calorie, high-fat breakfast meal in the timeframe required.
Key Exclusion Criteria:
- History or presence of significant cardiovascular abnormalities, heart murmur, pulmonary, hepatic, renal, haematological, gastrointestinal, endocrine, immunologic, dermatologic, neurological, or psychiatric disease as determined by the Investigator to be clinically relevant.
- Any musculoskeletal abnormality (severe tenderness with marked impairment of activity) or musculoskeletal toxicity (frank necrosis).
- Positive results at screening for Human Immunodeficiency Virus (HIV), Hepatitis B Surface Antigen (HBsAg), or Hepatitis C antibodies (HCV).
- Positive Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) results within 6 days prior to Day 1.
- Current or history of prolonged QT syndrome.
- Family history of Long-QT Syndrome or sudden death without a preceding diagnosis of a condition that could be causative of sudden death (such as known coronary artery disease, congestive heart failure or terminal cancer).
- Use of any drugs or substances known to be inducers of CYP enzymes and/or P-gp, including St. John's Wort, within 30 days prior to the first dose of study drug.
- Is lactose intolerant.
- History or presence of allergic, or adverse response to midazolam, digoxin, dolutegravir, tenofovir, lamivudine or any related drugs.

Measure Description |
Time Frame |
---|---|---|
TBAJ-876 effect on the pharmacokinetics of the CYP-3A4 substrate midazolam and the inhibition potential of TBAJ-876 on P-gp in healthy adult subjects
Time Frame: Day 1: pre-dose, 0.25, 0.5, 1, 2, 3, 4, 6, 8, 12, 24 hours; Day 20: pre-dose, 0.25, 0.5, 1, 2, 3, 4, 6, 8, 12, 24 hours
|
Geometric mean ratio of midazolam's area under the (plasma concentration vs. time) curve when co-administered with TBAJ-876 versus when administered alone, and similarly for the maximum concentration.
Inference will be based on analysis of variance applied to log-transformed parameters.
