Brief Summary

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.

Conditions

Spinocerebellar Ataxias; Spinocerebellar Ataxia Type 1; Spinocerebellar Ataxia Type 2; Spinocerebellar Ataxia 3; Spinocerebellar Ataxia Type 6; MSA-C

Outcome Measures

Primary Outcomes (1)

• Scale for the Assessment and Rating of Ataxia

  The total score on the Scale for the Assessment and Rating of Ataxia (SARA) The SARA is a tool for assessing ataxia. It has eight categories with an accumulative score ranging from 0 (no ataxia) to 40 (most severe ataxia). When completing the outcome measure each category is assessed and scored accordingly. Scores for the eight items range as follows: Gait (0-8 points), Stance (0-6 points), Sitting (0-4 points) Speech disturbance (0-6 points) Finger chase (0-4 points) Nose-finger test (0-4 points) Fast alternating hand movement (0-4 points) Heel-shin slide (0-4 points) Once each of the 8 categories have been assessed, the total is calculated to determine the severity of ataxia. For motor activities of the four extremities (items 5-8), assessments are performed bilaterally, and the mean values are used to obtain the total score. A higher score would indicate a worsening in ataxia. A lowered score may indicate the ataxia is improving.

  Up to 12 months

Eligibility Criteria

• Age: 18 Years - 75 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Informed Consent a. Subjects (or legally acceptable representative as required by the IRB/IEC) must provide a written signed informed consent form/forms (IRB/EC specific) prior to the initiation of any protocol required procedures.
• Age and Sex a. Male and female outpatient subjects between the ages of 18 - 75, inclusive
• Target Populations
• a. Subjects with (1) a known or suspected diagnosis of a specific hereditary ataxia: SCA3/dizziness-predominant or SCA1, SCA2, SCA3, SCA6, already taking Riluzole for more than 8 weeks; (2) non-genetic pure cerebellar ataxia; (3) MSA-C: i. SCA subjects should have confirmed genotypic diagnosis from a CLIA-certified lab or a family member that has had such testing.
• ii. Alternatively, subjects must be willing to undergo genetic testing from a CLIA-certified lab if testing has not been previously done on the study subject and a copy of results is not available for verification.
• b. Ability to ambulate 8 meters without assistance (canes and other devices allowed); c. Determined by the investigator to be medically stable at Baseline as assessed by medical history, physical examination, laboratory test results available in medical record, and electrocardiogram testing available in medical record. Subjects must be physically able and expected to complete the trial as designed; d. Minimum of 6 years of education; e. Subjects must have adequate hearing, vision, and language skills to perform interviews as specified in the protocol; f. Subjects must be able to understand and agree to comply with the prescribed dosage regimens and procedures; report for regularly scheduled office visits; and reliably communicate with study personnel about adverse events and concomitant medications; g. Women of childbearing potential (WOCBP) and men must be using an acceptable method of contraception to avoid pregnancy throughout the study and for up to 30 day after the last dose of investigational product in such a manner that risk of pregnancy is minimized. The requisite drug interaction studies to determine the interaction of BHV-4157 with oral contraceptives have not been performed to date. It is therefore not possible to determine the efficacy of oral contraceptives as an effective method of contraception for WOCBP who participation this study. Oral estrogen and progestin hormonal contraceptives as a sole method of contraception are therefore prohibited. It is required that all WOCBP use two methods of contraception for the duration of the study (i.e. beginning at first treatment to 30 days after the last dose of study drug).The two methods should include one barrier method (ex. condom with spermicidal gel, intrauterine devices, cervical cap etc.) and one other method. The other method could include oral contraceptives or another barrier method.
• h. Women of childbearing potential must have a negative serum pregnancy test at screening and a negative urine pregnancy test within 72 hours of dosing.

You may not qualify if:

• <!-- -->
• Target Disease Exceptions
• a. Clinical history of stroke. Note: Subjects with a history of transient ischemic attack (TIA) may be enrolled, if it occurred at least 3 months prior to screening and the subject is prescribed appropriate treatment \[e.g., platelet aggregation inhibitors\]; b. Immunocompromised subjects. Note: Subjects taking a systemic immunosuppressive agent may enter treatment phase if they are on a stable dose, have no clinically relevant immunosuppression, and have a white blood count (WBC) within normal limits; c. Active liver disease or a history of hepatic intolerance to medications that in the investigator's judgment, is medically significant; d. History of medically significant gastrointestinal (GI) illnesses including: i. A current diagnosis of active, peptic ulceration or gastrointestinal bleeding within the last 6 months and/or chronic inflammatory bowel disease at screening; ii. A history of any gastrointestinal surgery that impacts the absorption of study drug; iii. Chronic or frequent episodes of loose stools; bowel movements; e.

(Note: Subjects with a history of localized skin cancer, basal cell or squamous cell carcinoma, may be enrolled in the study as long as they are cancer free prior to randomization. Subjects with other localized cancers (without metastatic spread) who have previously completed their course of treatment more than 2 years prior to baseline, are not currently receiving treatment and have been in remission may be enrolled only if, in the opinion of the investigator, there is no expectation for recurrence or further cancer treatment during the study period. Antihormonal therapy (e.g., tamoxifen) is allowed if the subject's cancer is in remission and the subject is on maintenance therapy to reduce their risk of recurrence; g. Any unstable cardiovascular (includes uncontrolled hypertension), pulmonary, gastrointestinal, or hepatic disease 30 days prior to screening; h. End-stage cardiovascular disease (e.g., Congestive Heart Failure New York Heart Association/CHF NYHA Class III or IV or unstable angina); i.

History of neurosyphilis (as indicated by a positive rapid plasma reagin \[RPR\] test and a positive confirmatory test); l. History of drug or alcohol abuse within 12 months as defined by DSM-IV-TR-TR criteria; m. History or evidence of any medical, neurological or psychological condition that would expose the subject to an undue risk of a significant adverse event or interfere with assessments of safety and efficacy during the course of the trial as determined by the clinical judgment of the investigator; n. History of chronic pulmonary disease or chronic pulmonary symptoms
• Physical and Laboratory Test Findings
• a. Uncontrolled hypertension at screening (e.g., repeated diastolic measurements ≥ 96 mmHg); b. Subjects with history of hypothyroidism may participate in the study, provided they are euthyroid on stable thyroid replacement therapy for at least 3 months prior to Baseline, and therapy is expected to remain stable during the course of the study; c.
