Machado–Joseph Disease clinical trials at UCLA

24 adults, between the ages of 18 and 75 years, with cerebellar ataxia will be enrolled in a 12 week trial of BHV-4157 for treatment of ataxia. BHV-4157 is a pro-drug of riluzole (which is currently FDA-approved for ALS, Lou Gehrig's disease). There will be 5 visits to UCLA required--Screening when general and neurological examination, blood and urine testing, ECG, and questionnaires will be administered; Baseline when general and neurological examination and questionnaires will be administered and study drug dispensed; Week 4 and Week 12 when general and neurological examination, blood and urine testing, ECG, and questionnaires will be administered; 2 weeks after finishing study drug when general examination and blood testing will be completed. There is an option for a 36 week extension of the study drug trial.

The purpose of this study is to compare the efficacy of Troriluzole (200 mg once daily) versus placebo after 48 weeks of treatment in subjects with spinocerebellar ataxia (SCA).
