Official title

Double Blind Placebo-Controlled Phase I/II Clinical Trial of Idebenone in Patients With Primary Progressive Multiple Sclerosis

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Background: * Multiple sclerosis (MS) is an inflammatory disorder of the central nervous system that progressively weakens and destroys the pathways of the nervous system. About 10 percent to 15 percent of patients develop primary-progressive MS (PP-MS), characterized by progressive accumulation of disability from the disease onset, without any marked improvements or relapses. There are currently no effective treatments for PP-MS. * Idebenone is a manmade drug that is similar to a naturally occurring compound known as coenzyme Q10, a common dietary supplement. Research data suggest that idebenone may be able to limit demyelination and death of brain cells and thereby slow or halt the progression of neurological dysfunction such as that occurring in MS. Objectives: \- To evaluate the safety and effectiveness of using idebenone to treat primary progressive MS. Eligibility: \- Individuals between 18 and 65 years of age who have been diagnosed with primary progressive multiple sclerosis. Design: * The study will last 3 years and will be divided into two parts: a 1-year pretreatment baseline and 2 years of treatment with either idebenone or a placebo. * Pre-treatment study: approximately 5 clinic visits over 1 year. * Visit 1: Comprehensive medical history and neurological examination, with brain scans and neurological tests. * Visit 2: Magnetic resonance imaging (MRI) scan of the spine and lymphocytapheresis (withdrawal of white blood cells for testing). * Visit 3: Lumbar puncture. * Visit 4: Skin biopsy. * Visit 5: Repeat MRI of the brain and spinal cord, as well as neurological tests; these tests will be scheduled over 2 days. * After the five pretreatment visits, patients will receive a 6-month supply of study medication (either idebenone or a placebo) to take three times a day with food * Patients will continue to have regular followup clinic visits with brain MRI scans, blood tests, and other evaluations of brain and nervous system function. Randomly selected participants will have additional MRI scans for further safety precautions.
