About this study

Official title: A Multicenter Randomized Placebo-controlled Double-blind Study to Assess Efficacy and Safety of Glutamine and Creatine Monohydrate in Duchenne Muscular Dystrophy

This study will help to determine the effectiveness of glutamine and creatine as a possible therapy for DMD. Boys with DMD who are enrolled in this trial will be randomly chosen to receive creatine monohydrate or glutamine or an inactive placebo orally for six months. Once a month during the six-month treatment period, the study participants will have their muscle strength evaluated using manual and computerized testing methods. This study will be conducted at several CINRG Centers throughout the U.S., Belgium, Israel and Puerto Rico. This study is supported by the Muscular Dystrophy Association.

Read the detailed description

PURPOSE OF THE STUDY The purpose of this study is to see if children with Duchenne muscular dystrophy (DMD) who are given glutamine (a nutritional supplement) or creatine monohydrate (a nutritional supplement) have changes in strength compared to children who are given no medicinal treatment. Children who are chosen to be in this research study will be diagnosed with DMD, be between the ages of 5 and 10 years old, and will not have participated in any other DMD clinical trials within the last year, and will not have been on medications that disqualify them from participation in this trial. All children in this clinical trial are entered at the discretion of the doctors in charge of the study. During the first and second visits, children who fulfill the criteria for participation in the clinical trial will be determined. We expect 50 subjects to participate at CINRG centers worldwide.

PROCEDURES

Children will be randomized (a procedure like flipping a coin) into one of three groups: treated with glutamine, treated with creatine monohydrate, or untreated (placebo: a sugar pill with no medication). Neither parents, children, nor the doctors treating the children will know the group each child has been assigned to. Because of the study design, there is a possibility that children will receive no treatment (placebo group) during the clinical trial. During the trial children must take one supplement mixed with water in the morning and supplements mixed with water each night.

Nine (9) clinic visits are required to complete this clinical trial. During visits to the clinic, each child will be evaluated by members of the research team to determine the child?s strength. Strength will be measured in different ways: manual testing, quantitative testing, and the usual measures used during visits to the neurologist (child will be asked to rise from the floor, walk across room, etc.). Manual testing is the way strength is usually measured by your child?s doctor. The quantitative muscle strength test (QMT) is a mechanical way to measure strength: the child sits/lays on an examining table and is asked to pull/push a strap. This test will determine the strength of different muscle groups in kilograms of force. An electrocardiogram (ECG, a heart test) will be performed during screening visit 2 and month 6 and blood (a small amount equal to about 2 to 3 tablespoons) will be drawn on screening visit 2 and months 1, 3 and 6. Urine tests will be done at screening visit 2 nd months 1, 3 and 6 to monitor kidney function.

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Creatine Monohydrate and Glutamine in people with Muscular Dystrophy, Duchenne, run by Cooperative International Neuromuscular Research Group 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 10 inclusion and 7 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 27 Oct 2011. 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 combined 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.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00016653, which also lists 1 linked publication.

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 27 Oct 2011.
