About this study

Official title: A Pilot, Phase 1, Single-site, Single-dose, Randomized, Open-label, Two-treatment, Two-sequence, Four-period Replicated Crossover Study Evaluating the Within-subject Pharmacokinetic Variability and Relative Bioavailability of the Phase 3 and Common Blend Formulations of Eliglustat in Healthy Adult Subjects.

The primary objective of this pilot study is to determine the within-subject pharmacokinetic (PK) variability and relative bioavailability of single oral 150-mg doses of eliglustat administered as the Phase 3 formulation (3x50-mg capsules) and the common blend proposed commercial formulation (1x150-mg capsule) in healthy adult subjects, which will be used to plan and support the design of a subsequent bioequivalence study.

Read the detailed description

This will be a single-site, single-dose, randomized, open-label, two-treatment, two-sequence, four-period replicated crossover study in healthy adult subjects. The study will comprise a screening period, four treatment periods with a 7-day washout between dosing in each period, and a safety follow-up visit.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Eliglustat, common blend proposed commercial formulation and Eliglustat, Phase 3 capsule formulation in people with Healthy Volunteer, run by Genzyme, a Sanofi Company 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 9 inclusion and 20 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 23 Mar 2015. 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?

Eliglustat plasma concentration over time (time frame: Plasma concentration-time data will be obtained pre-dose (within 30 minutes prior to dosing) and at 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 12, 18, 24, 36, 48, and 72 hours after dosing in each treatment period.). 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 23 Mar 2015.
