About this study

Official title: AM1476 - A Phase I, Double-blind, Placebo-controlled, Single- and Multiple-oral Dose, Safety, Tolerability, and Pharmacokinetic Study in Healthy Subjects

This is a First in Human (FIH), double-blind, randomised, placebo-controlled study designed to evaluate safety, tolerability and pharmacokinetics (PK) of single and multiple ascending oral doses of AM1476 in healthy subjects.

Read the detailed description

Part A (SAD); In the SAD part of the study, single oral doses of AM1476 will be administered in up to 9 sequential groups, each consisting of 8 subjects randomised to receive either AM1476 or placebo in a 3:1 ratio. The first 2 subjects in each group will be dosed in a sentinel fashion, 1 subject will receive AM1476 and the other will receive placebo as randomised.

Part B (MAD); The MAD part of the study will explore multiple ascending dosing of AM1476 for 10 days. AM1476 will be administered in up to 6 sequential groups, each consisting of 8 subjects randomised to receive either AM1476 or placebo in a 3:1 ratio.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing AM1476 in people with Safety and Tolerability, run by AnaMar AB at 1 site in United Kingdom.

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 28 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 2 Aug 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 Kingdom. 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?

Yes. Results are posted in the registry (first posted 2 Aug 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?

Number of Participants With Treatment-Emergent Adverse Events (time frame: Through study completion, an average of 7 weeks). 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 2 Aug 2024.
