Creatine and Glutamine in Steroid-Naive Duchenne Muscular Dystrophy Clinical Trials Data presented on Clinical Trials Search is not meant to be a substitute for qualified health advice, visits or treatment with a real mD. We are not doctors. Always consult your doctor about Creatine and Glutamine in Steroid-Naive Duchenne Muscular Dystrophy conditions. Clinical Trials Search.org is a site devoted to listing clinical research studies in human subjects. Creatine and Glutamine in Steroid-Naive Duchenne Muscular Dystrophy Clinical research trials and Creatine and Glutamine in Steroid-Naive Duchenne Muscular Dystrophy healthcare trials happen in many of places across the United States. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials generally assess the effectivity of new drugs. The purpose of the studies / projects is to solve particular human medical questions. Clinical trials are a popular way for doctors, government agencies, and private sector companies to discover cures for all varieties of conditions, such as Creatine and Glutamine in Steroid-Naive Duchenne Muscular Dystrophy. Creatine and Glutamine in Steroid-Naive Duchenne Muscular Dystrophy Clinical Trials and other clinical trials allow volunteers to have health treatment alternatives before they are available to the masses. Some times the human subjects obtain treatment for without cost, and sometimes they are compensated for their time. Occasionally there is a cost for a Creatine and Glutamine in Steroid-Naive Duchenne Muscular Dystrophy clinical trial. Test subjects oftentimes receive the most effective healthcare possible for their Creatine and Glutamine in Steroid-Naive Duchenne Muscular Dystrophy condition. Dangers are a reality, however, and may include extra or frequent physician visits, healthcare dangers (possibly life-jeopardising), and/or the treatment being uneffective. Trials are federally governed with rigorous guidelines to protect clinical trials patients.

Creatine and Glutamine in Steroid-Naive Duchenne Muscular Dystrophy
For Condition: Muscular Dystrophy, Duchenne
Status: No longer recruiting
Sponsor(s): Cooperative International Neuromuscular Research Group ,
Synopsis: 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.
Details: 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.
Eligibility:
