About this study

Official title: A Randomized, Double-Blind, Placebo-Controlled, Parallel Group 26-Week Dose-Investigating Study to Explore the Pharmacokinetics, Pharmacodynamic Effects, Efficacy, Safety and Tolerability of RO5186582 in Children With Down Syndrome Aged 6-11 Years

This study will evaluate the safety, tolerability, efficacy, and pharmacokinetic and pharmacodynamic activity of 3 different dosages of RO5186582 compared with placebo. A total of approximately 46 participants will be enrolled, in order to have at least 32 evaluable, and will be randomly assigned to 1 of 4 treatments in a 1:1:1:1 ratio, with 9 children per treatment arm. The target ratio between 6-8 years and 9-11 years age groups is approximately 1:1 in each treatment arm, with a minimum of 3 children per age group in each treatment arm.

What participants receive

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

  • PlaceboDrug

    Participants will receive matching placebo PO BID. Study medication will first be administered on Day 1, and only the morning dose will be given on the last day of treatment (Week 26).

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing RO5186582 in people with Down Syndrome, run by Hoffmann-La Roche at 9 sites 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 2 inclusion and 8 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 6 Jul 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 9 sites 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.

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 stopped early (reason given: Study was terminated due to data from another study showing no efficacy. There were no safety issues of concern.). 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?

Percentage of Participants With Adverse Events (AEs) (time frame: Baseline up to Week 6). The study lists 9 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 6 Jul 2017.
