Official title

Phase I Study of Oral Guanabenz for Multiple Sclerosis

Brief summary

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

Background: \- People with multiple sclerosis (MS) get lesions in their brain and spinal cord. These cause neurological symptoms and sometimes disability. Researchers want to see if a blood pressure drug called guanabenz can repair lesions and help people with MS. Objective: \- To see if guanabenz is safe and well tolerated in people with MS. Eligibility: \- People 18 55 years old with MS who have taken glatiramer acetate for the past year. Design: * Participants will be screened in a separate protocol. For 2 months, they will be examined and have magnetic resonance imaging (MRI) scans. This will decide if they are in the Stable or Active MS study group. * The study will last 5 months. There will be up to 11 visits, 5 overnight. * Visit 1: overnight stay at the clinic: * Medical history and physical exam. * Health questionnaire * Bladder ultrasound scan * Brain MRI * Electrocardiogram (EKG) to measure heart electrical activity * Blood will be drawn through an intravenous (IV) line. * Participants may have tests of strength, muscle tone, and movement. * They will get their first dose of the study drug, a tablet taken once a day. * Participants will take the study drug at home and keep a medicine diary. * The dose will slowly increase. Each time, participants will stay overnight at the clinic. They will have a physical exam, EKG, MRI, and IV blood draw. * Visit 6: Participants will have a physical exam, MRI, and blood drawn. They will get a schedule to slowly lower their drug dose and stop taking guanabenz. * Participants will have 2 final visits. They will have a physical exam, EKG, MRI, and IV blood draw.
