About this study

Official title: A Randomized, Double-Blind, Placebo-Controlled, Multi-Center Phase 1b Study to Evaluate the Safety, Efficacy and Mircobiological Response of Oral ABI-M201 in Subjects With Mildly-to-Moderately Active UC With Ongoing Mesalamine Treatment

Phase 1B randomized, double-blind, placebo-controlled, two-cohort clinical trial of ABI-M201 in adult subjects with mildly-to-moderately active Ulcerative Colitis(UC) and ongoing treatment with mesalamine.

Read the detailed description

This multi-center randomized, double-blind, placebo-controlled study will evaluate the safety of ABI-M201 and its effects on disease activity measures in men and women with mildly-to-moderately active UC and ongoing treatment with mesalamine. The study will consist of 2 sequential, non-overlapping participant cohorts, separated by intervening interim analysis (IA). Both cohorts will involve 8-weeks of study drug treatment. Interim data from the initial treatment cohort (Cohort A) will inform decision to advance to the subsequent second cohort (Cohort B) and its dose selection. 20 subjects will be randomized to cohort A (1:1 allocation) and receive treatment with 1 capsule per day of ABI-M201 versus Placebo. 24 subjects will be randomized to cohort B (3:1 allocation) and receive treatment with up to 5 capsules one time a day of ABI-M201 versus Placebo.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ABI-M201 in people with Ulcerative Colitis Chronic Mild and Ulcerative Colitis Chronic Moderate, run by Assembly Biosciences at 11 sites in 2 countries.

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 3 inclusion and 7 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: stopped early, as of the sponsor's last update on 19 Mar 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 11 sites in United States, Canada. 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 was stopped early (reason given: Sponsor Decision). Results are not available in the source record.

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?

Incidence of Treatment-Emergent Adverse Events (time frame: 8-weeks). The study lists 2 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 19 Mar 2021.
