About this study

Official title: A Phase 1, Open-Label, Fixed Sequence, Drug-Drug Interaction Study to Evaluate the Effect of Inhibition of Uridine 5'-Diphosphate-glucuronosyltransferases (UGTs) on the Pharmacokinetics of Ecopipam Tablets and Its Active Metabolite (EBS-101-40853) in Healthy Subjects

This is a single center, open-label, fixed sequence, drug-drug interaction (DDI) study in healthy subjects.

Read the detailed description

Following a 28-day Screening period, eligible subjects will enter the clinical research unit (CRU) and will be enrolled into either Cohort A or B. Subjects in both cohorts will receive a single dose of ecopipam on Day 1. On Day 7, subjects will begin taking a UGT inhibitor according to their assigned cohort. Subjects in Cohort A will receive mefenamic acid 250 mg every 6 hours for 7 days, while subjects in Cohort B will receive divalproex sodium ER 1250 mg once a day for 10 days. A single oral dose of ecopipam will also be administered to Cohort A on Day 7, 1 hour after the first dose of mefenamic acid, and to Cohort B on Day 10, 1 hour after administration of divalproex sodium ER. Subjects in Cohort A will continue taking mefenamic acid through the evening of Day 13 and will remain in the CRU until discharged on Day 14/ET. Subjects in Cohort B will continue taking divalproex sodium ER through Day 16 and will remain in the CRU until discharge on Day 17/ET.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ecopipam HCL, Mefenamic acid and Divalproex Sodium ER in people with Drug Interaction, run by Emalex Biosciences 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 5 inclusion and 14 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 22 Jul 2021. 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. 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?

Cmax of ecopipam in the presence of mefenamic acid (time frame: Up to Day 16). The study lists 12 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 22 Jul 2021.
