About this study

Official title: A Randomized, Double-Blind, Placebo-Controlled Efficacy and Safety Trial of Trehalose for the Treatment of

BB-OPMD-202 is a randomized, double-blind, placebo-controlled study of IV trehalose for treatment of OPMD. The study includes a 4-week screening period, a 24-week blinded treatment period during which patients will receive weekly infusions of trehalose or placebo, followed by a 24-week open-label extension period during which all patients will receive weekly infusions of trehalose. Patients will undergo a safety follow-up assessment 4 weeks after their last treatment.

Read the detailed description

After signing informed consent, patients will undergo two rounds of ice-cold water and nectar drinking tests at least 1 week apart to confirm oropharyngeal dysfunction. Patients who have confirmed oropharyngeal dysfunction, i.e., an ice-cold water drinking test time of 8 seconds or greater at both rounds, in addition to an SSQ score of >235, will be enrolled. Baseline values for all safety and efficacy parameters will be established during the screening period. Patients will be randomized in a 1:1 ratio, to trehalose or placebo, at the time of enrollment. Randomization will be stratified according to the patient's score on the SSQ at screening (≤ 799 or ≥ 800).

Patients randomized to trehalose will receive a 1-hour IV infusion of trehalose at a dose of 0.75 g/kg weekly for 24 weeks. Patients randomized to placebo (normal saline) will receive a weight-based equal volume of placebo weekly for 24 weeks.

After Week 24, patients may transition to an open-label extension of the study (extension period). During the extension period, patients will be treated with weekly infusion of trehalose at a dose of 0.75 g/kg for 24 weeks, followed by a 4-week safety follow-up (total duration of study = 56 weeks).

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Trehalose in people with Oculopharyngeal Muscular Dystrophy, run by Bioblast Pharma Ltd. at 3 sites in Canada.

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 17 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The record says: withdrawn, as of the sponsor's last update on 13 Jan 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 withdrawn before enrolling participants, so there are no results.

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?

Drinking Test Time (time frame: 24 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 13 Jan 2020.
