About this study

Official title: Companion Protocol for the ¹³C-Methacetin Breath Test Using the BreathID® MCS System for Conatus Phase 2 Study of Emricasan, an Oral Caspase Inhibitor, Under Protocol IDN-6556-17

This study is a companion protocol that will use the data generated by Conatus' study of emricasan under protocol IDN-6556-17.The IDN-6556-17 study is a Phase 2, multicenter, double-blind, placebo-controlled trial of Emricasan in subjects with decompensated non-alcoholic steatohepatitis (NASH) cirrhosis.

Read the detailed description

The protocol is intended to validate the ability of the MBT to predict deterioration by 48 weeks for all subjects, and at later time points for those followed longer, for subjects with decompensated NASH cirrhosis in the placebo treatment arm of Conatus' study IDN-6556-17.

As one of the Conatus' study secondary objectives, this companion protocol is designed to assess improvement in liver metabolic function as measured by Methacetin Breath Test (MBT) [ Time Frame: Baseline - Final Treatment Visit (at least 48 weeks to a max of 120 weeks) ].

Being tested
Methacetin Breath Test, Emricasan, Placebo oral capsule

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Methacetin Breath TestCombination product

    A breath analyzer will be used to measure changes in carbon 12 to carbon13 ratio as a result of metabolism of the Methacetin substrate before and after treatment.

  • EmricasanDrug

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Subjects Experiencing a High Risk Event Based on a 5.5%/Hour Cut-off

    Binary diagnosis of subjects that are at high risk to develop a deterioration event as determined by the Methacetin Breath Test (MBT) derived from an algorithm developed under other Exalenz clinical studies using a pre-designed cutoff of Percentage Dose Recovery (PDR) peak of < 5.5%/hour. The data was collected and analyzed agnostic to the intervention.

    Measured: 1 hour for MBT for assessment of this diagnostic outcome assessed during screening

Model description
The study treatment duration will be at least 48 weeks with study visits every 4 weeks up to Week 48 and every 8 weeks after Week 48. All subjects will continue treatment until the last subject in the study reaches 48 weeks in the study. At least 30% of subjects randomized should have baseline MELD score ≥15 and ≤20. For each subject, the study will consist of: * Screening period of up to 4 weeks * Randomized, double-blind treatment period of at least 48 weeks * A follow-up visit 2 weeks after completion of study drug treatment The duration of each subject's participation will be at least 54 weeks for those completing the entire study.

Questions about this trial

What is this clinical trial studying?

A study testing Methacetin Breath Test and Emricasan in people with Decompensated Cirrhosis, run by Meridian Bioscience, 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 21 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 20 Dec 2022. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 16 Dec 2020). 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 Subjects Experiencing a High Risk Event Based on a 5.5%/Hour Cut-off (time frame: 1 hour for MBT for assessment of this diagnostic outcome assessed during screening). 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 20 Dec 2022.
