About this study

Official title: A Phase 1, Drug-Drug Interaction Study to Evaluate the Safety, Tolerability, and the Induction Potential of TBAJ-876 on CYP3A4 and P-glycoprotein and the Inhibition Potential of TBAJ-876 on P-glycoprotein in Healthy Adult Subjects

A Phase 1, Drug-Drug Interaction Study to Evaluate the Safety, Tolerability, and the Induction Potential of TBAJ-876 on CYP3A4 and P-glycoprotein and the Inhibition Potential of TBAJ-876 on P-glycoprotein in Healthy Adult Subjects

Read the detailed description

This study was a two-part, open-label drug-drug interaction study conducted in one study center in the United States. Two groups were planned, Group 1 and Group 2. Group 2 to be conducted based on the Group 1 results.

Group 1 to 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 was only to be conducted if the results of Group 1 show that TBAJ-876 is a moderate inducer of either CYP3A4 (geometric mean ratio [GMR] of midazolam area under the curve [AUC] <0.50 when co-administered with TBAJ-876) or P-glycoprotein (GMR of digoxin AUC <0.50 when co-administered with TBAJ-876) or a moderate inhibitor of P-glycoprotein (GMR of digoxin AUC ≥2.0 when co-administered with TBAJ-876). These results were used to decide that a second phase of the study was not needed.

If Group 1 concluded that TBAJ-876 is a moderate inducer or inhibitor, Group 2 had intended to quantify the magnitude of inhibition or induction of TBAJ-876 of 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 was assessed throughout the study for all subjects. Safety assessments included physical examinations, vital signs, serial ECGs, adverse events (AEs), clinical and laboratory tests (including hematology, serum chemistry, coagulation, and urinalysis).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. TBAJ-876 Effect on the Pharmacokinetics of the CYP-3A4 Substrate Midazolam in Healthy Adult Subjects: Pharmacokinetic Parameters AUC

    Geometric mean and range of midazolam's area under the (plasma concentration vs. time) curve when co-administered with TBAJ-876 versus when administered alone.

    Measured: 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

  2. TBAJ-876 Effect on the Pharmacokinetics of the CYP-3A4 Substrate Midazolam in Healthy Adult Subjects: Pharmacokinetic Parameters CMAX

    Geometric mean and range of midazolam's maximum concentration when co-administered with TBAJ-876 versus when administered alone.

    Measured: 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 and Cmax when co-administered with TBAJ-876 versus when administered alone. Inference will be based on analysis of variance applied to log-transformed parameters.

    Measured: 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 of digoxin'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.

    Measured: Day 2: pre-dose, 0.5, 1, 2, 3, 4, 6, 8, 12, 24, 48, 72, 96 hours; Day 21: pre-dose, 0.5, 1, 2, 3, 4, 6, 8, 12, 24, 48, 72, 96 hours

    Measured: Day 2: pre-dose, 0.5, 1, 2, 3, 4, 6, 8, 12, 24, 48, 72, 96 hours; Day 21: pre-dose, 0.5, 1, 2, 3, 4, 6, 8, 12, 24, 48, 72, 96 hours

  6. TBAJ-876 Effect on the Pharmacokinetics of the P-gp Substrate Digoxin: Geometric Mean Ratio

    Geometric mean ratio of digoxin's area under the (plasma concentration vs. time) curve and Cmax 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.

    Measured: Day 2: pre-dose, 0.5, 1, 2, 3, 4, 6, 8, 12, 24, 48, 72, 96 hours; Day 21: pre-dose, 0.5, 1, 2, 3, 4, 6, 8, 12, 24, 48, 72, 96 hours

Secondary outcomes (1)
  1. Number of Participants With Treatment-Related Adverse Events (TEAE) in Group 1 Population

    Participants will be monitored for any adverse events from the signing of the consent form until the end-of-study visit. The Investigator or a Sub-Investigator will assess its relationship to the study drug.

    Note about ST segment elevation which was reported as a treatment-related adverse event. Upon review of the screening ECG, early repolarization was noted and therefore the ST segment elevation was considered pre-existing and not a TEAE however the AE remained in the database instead of being removed.

    Measured: from date of the start of treatment to the end of study at 25 days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing TBAJ-876, Midazolam and Digoxin in people with Pulmonary Disease and Tuberculosis, Pulmonary, run by Global Alliance for TB Drug Development at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 8 Oct 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 8 Oct 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

TBAJ-876 Effect on the Pharmacokinetics of the CYP-3A4 Substrate Midazolam in Healthy Adult Subjects: Pharmacokinetic Parameters AUC (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). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Oct 2024.
