Protein Deficiency clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

NCT ID: NCT00840112 Terminated - Clinical trials for Peripheral Neuropathy

Vitamin E Treatment for Long-Chain 3-Hydroxyacyl Coenzyme A (CoA) Dehydrogenase (LCHAD) Associated Neuropathy

Start date: July 2010
Phase: N/A
Study type: Interventional

Purpose: People with a genetic defect in the ability to burn fat can also develop a problem with the nerves in their feet. The nerve problem, or neuropathy, can limit their ability to walk. Part of the treatment of their genetic defect in the ability to burn fat is to eat a very low fat diet. Vitamin E is found only in fatty foods like oils and nuts. People with a genetic defect in the ability to burn fat may have low vitamin E because of their low fat diet. The purpose of this study is to test whether vitamin E supplements can improve the nerve function in the feet of people with a genetic defect in the ability to burn fat. Procedures: Blood samples will be drawn at the beginning of the study, after 2 months and after 6 months of vitamin E supplements. The blood will be analyzed for plasma vitamin E concentrations. Around the time of each blood draw subjects will record all the food and beverages he or she consumes for three days. The subject will send the record to the investigator. Subjects will have a physical exam by a doctor specializing in nerves, a neurologist before and after taking vitamin E. They will have nerve function measured with a test called a nerve conduction velocity or NCV. Subjects will be given 800 international units (IU) of vitamin E per day for 6 months.
