Study of Rifampicin in Multiple System Atrophy

Summary

The purpose of this study was to determine whether Rifampicin was effective in slowing or reversing the progression of multiple system atrophy (MSA). Research studies indicate that there is an abnormality in protein synthesis and structure in parts of the brain responsible for MSA (protein misfolding) and the drug Rifampicin could potentially prevent or reverse this protein alteration. The study was done on participants with early MSA. The study consisted of taking the drug 2 times a day for 12 months. Participants underwent an evaluation of symptoms and function and will underwent a neurologic examination at the beginning of the study, at 6 months and at 12 months. They were also be contacted at 3 and 9 months by telephone. Studies were done at 10 participating sites.
