About this study

Official title: A Phase 1, Single-Dose, Randomized, Placebo- and Positive-Control, Four-Way, Crossover Study for the Evaluation of the Effect of Epetraborole on QT Intervals in Healthy Adult Subjects

A single-center, 4-way crossover study to evaluate the effect of single therapeutic and supratherapeutic oral doses of epetraborole on the heart rate (HR) corrected QT interval (QTc) by assessing concentration-QT (C-QT) relationship using exposure-response modeling.

Read the detailed description

On Day 1 of each period, subjects will receive 1 of 4 treatments: a single therapeutic dose of epetraborole (Treatment A), a single supratherapeutic dose of epetraborole (Treatment B), a single dose of epetraborole-matching placebo (Treatment C), or a single dose of moxifloxacin (Treatment D). Cardiodynamic ECGs and PK blood samples for epetraborole, metabolite M3, and moxifloxacin (as applicable) will be collected predose and for 24 hours postdose in each period.

There will be a washout of at least 10 days between doses.

Model description
Screening of subjects will occur within 28 days prior to the first dosing. Subjects will be housed on Day -1, at the time indicated by the CRU, until completion of study procedures on Day 2 of each period. On Day 1 of each period, subjects will receive 1 of 4 treatments: a single therapeutic dose of epetraborole (Treatment A), a single supratherapeutic dose of epetraborole (Treatment B), a single dose of epetraborole matching-placebo (Treatment C), or a single dose of moxifloxacin (Treatment D). Cardiodynamic ECGs and PK blood samples for epetraborole, metabolite M3, and moxifloxacin (as applicable) will be collected predose and for 24 hours postdose in each period. There will be a washout of at least 10 days between doses. Safety will be monitored throughout the study by repeated clinical and laboratory evaluations, including a follow-up visit approximately 14 days after the last dose.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Epetraborole and Moxifloxacin in people with Healthy Volunteers, run by AN2 Therapeutics, Inc 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 6 inclusion and 20 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 21 Dec 2023. 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. Some participants in this study may receive a placebo. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Changes to QTc interval (time frame: Study Day -1 to Study Day 2). 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 21 Dec 2023.
