NCT00392015
The purpose of this study is to determine whether a new investigational malaria vaccine is safe, well tolerated and effective against experimental exposure to malaria when given to healthy people with no previous exposure to malaria. The vaccine consists of a modified form of a relatively common virus, adenovirus, that has been rendered incapable of replicating itself and modified to deliver the malaria gene of interest to the body's cells allowing the cell to manufacture the protein encoded by the gene and present it to the body's immune system in a more natural and presumably effective way.

NCT01854359
Background: \- The Idebenone in Patients With Primary Progressive Multiple Sclerosis (IPPoMS) trial tested a new drug for multiple sclerosis. In the IPPoMS trial, participants took either idebenone or placebo. Researchers want to give idebenone to all participants for 1 year. It is still not certain whether idebenone can slow the progression of multiple sclerosis, but this study may help answer that question. Objectives: * To provide idebenone to all participants on the IPPoMS trial. * To collect data on the safety and effectiveness of idebenone for primary progressive multiple sclerosis. Eligibility: \- Individuals at least 18 years of age who have completed 3 years in the IPPoMS trial. Design: * The first study visit for this trial will happen on the same day as the last visit for the IPPoMS trial. * Participants will provide a blood samples and will have a lumbar puncture. They will also receive a new supply of idebenone to take three times a day with food. They will keep a diary to report on any side effects. * After this first treatment visit, participants will have two follow-up visits to the NIH 6 months apart. These visits may be scheduled over multiple days. Participants will provide blood and urine samples. They will also have imaging studies of the brain and spine. * Participants will have phone calls with the study researchers to provide updates on their condition and any side effects.
