About this study

Official title: A Phase 1, Double-blind, Placebo-controlled, Dose-Ranging Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Food Effect of Epetraborole Tablets Administered for up to 28 Days in Healthy Adult Subjects

This is a Phase 1b double-blind, placebo-controlled, dose-ranging study to evaluate the safety, tolerability, PK, and food effect of epetraborole tablets administered to healthy adult subjects for up to 28 days.

Read the detailed description

Up to 56 healthy male and female adult subjects will be enrolled into one of 7 Dose Cohorts (Dose Cohorts 1 to 7; n = 8 per cohort). Cohort 7 (n = 8) is a Food Effect Cohort and subjects will receive a single dose of epetraborole or placebo in a Fasted state (Period 1) followed by a second dose of the same Investigational Product (IP) in a Fed state (Period 2) after a washout period of at least 7 days (+3 days). The dose of IP to be administered in Cohort 7 will be determined based on the Safety Monitoring Group recommendation following evaluation of safety and available PK data (at least 14 days) in Cohort 1 through Cohort 6. Up to 16 additional subjects may be included for the purposes of cohort expansion or to explore a dose intermediate to previously evaluated doses.

Subjects in each Dose Cohort (n=8) will be randomized 3:1 to receive epetraborole (n=6) or matching placebo (n=2) and will receive oral doses of epetraborole or placebo. Investigational product will be administered with approximately 240 mL (8 fluid ounces) of non-carbonated water to each subject following an overnight fast of at least 8 hours, except for Period 2 (Fed) of Cohort 7. Subjects will be required to fast for a minimum of 2 hours following administration of IP.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Epetraborole in people with Healthy Volunteers, run by AN2 Therapeutics, Inc at 1 site in Australia.

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 19 inclusion and 16 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 Mar 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 Australia. 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?

Evaluate the Incidence of Treatment Emergent Adverse Events at Baseline and Through Study Completion (time frame: From Day 1 through last follow-up visit (7 days after last dose)). The study lists 13 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 21 Mar 2024.
