About this study

Official title: A Phase 1 Relative Bioavailability Study Comparing The Pharmacokinetics Of Aramchol Meglumine Granules For Oral Suspension To Aramchol Free Acid 300 mg Tablets In Healthy Volunteers

This is a Phase 1 Relative Bioavailability Study Comparing The Pharmacokinetics Of Aramchol Meglumine (AM) Granules For Oral Suspension To Aramchol Free Acid (AA) 300 mg Tablets In Healthy Volunteers

Read the detailed description

A single center, 3-period, open-label, crossover study in healthy male and female volunteers who will receive 2 single doses of Aramchol meglumine (AM) and 1 single dose of Aramchol free acid (AA) under fasting conditions.

A single 400 mg dose of Aramchol meglumine (AM; Test 1) will be administered to all study subjects in Period 1.

The second dose of Aramchol meglumine (AM) will be between 200 mg and 800 mg and will be selected after review of the pharmacokinetics (PK) from Period 1.

In Periods 2 and 3, study subjects will be randomized 1:1 to receive the second dose of Aramchol meglumine (AM; Test 2) in one period and a 300 mg tablet of Aramchol free acid (AA; Reference) in the other period. Each product will be given under fasting conditions. The study periods will be separated by a wash-out period of at least 14 days.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Aramchol meglumine and Aramchol free acid in people with Healthy, run by Galmed Pharmaceuticals Ltd at 1 site in Bulgaria.

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 14 inclusion and 36 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 1 Jun 2026. 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 Bulgaria. 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 1 Jun 2026). 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?

Cmax of Aramchol (time frame: 8 days 19 blood samples were drawn in each study period: within 10 minutes pre-dose and 2, 3, 4, 6, 8, 10, 12,14, 18, 24, 30, 36, 48 (Day 3), 72 (Day 4), 96 (Day 5), 120 (Day 6), 144(Day 7), 168 hours (Day 8) post-dose.). The study lists 3 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 1 Jun 2026.
