Inclusion Criteria

1) Male and female of any race and > 6 years old; 2) Positive genetic test for SCA7; 3) Signed Informed Consent (in case of minors, written informed consent must be obtained by parents or legal representative).
Are the trial subjects under 18? yes
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range 29
F.1.3 Elderly (>=65 years) yes

Exclusion Criteria

1) Female subjects: pregnant or lactating women cannot participate in the study. Women of childbearing potential cannot participate unless willing to use highly effective contraception methods as combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation (oral, intravaginal or transdermal); progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable or implantable; intrauterine device (IUD); intrauterine hormone-releasing system (IUS); bilateral tubal occlusion; vasectomised partner; sexual abstinence. In case of use of oral contraception, women should have been stable on the same pill for a minimum of 3 months before taking study drug. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception. 2.) Subjects with a clinically significant or unstable medical or surgical condition that would preclude safe and complete study participation. Such conditions may include cardiovascular, pulmonary, hepatic, renal, severe systemic mycotic infections, metabolic diseases or malignancies; 3) Hepatic diseases with serum values of alanine aminotransferase, aspartate aminotransferase or bilirubin > 1·5 times above normal limit 4) Any medical or psychiatric condition that may affect the subject ability to give informed consent, or to complete the study, or if the subject is considered by the treating neurologist to be, for any other reason, an unsuitable candidate for this study; 5)Known hypersensitivity to any component of riluzole (Glentek).

Study & Design

• Study Type: Interventional clinical trial of medicinal product
• Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
Main Objective: To compare the two study arms for the proportion of patients who remain stable at SARA score and visual acuity at 18 months respect to run-in.;Secondary Objective: To evaluate the effect of riluzole on visual function using quantitative ophthalmologic assessments and on SARA score, as continuous values, assessing changes at 18 months compared to run-in.<br>To investigate the safety and tolerability of riluzole administered in SCA 7 patients.;Primary end point(s): The primary endpoints will be the proportion of patients with stable SARA score and visual acuity expressed as log MAR units at 18 months, in comparison with the same parameters as mean of t0-t3-t6 evaluations .;Timepoint(s) of evaluation of this end point: Months: 0, 3, 6, 18

Secondary Outcome Measures

Name	Time	Method
Secondary end point(s): The secondary endpoint will be quantitative ophthalmologic assessments (via a Farnsworth D15 Arrangement Test, Visual evoked, Electroretinography, Optical Coherence tomography, Computerized visual field examination) and SARA score as continuous values at 18 months, in comparison with the same parameters calculated for each patient as mean of t0-t3-t6 evaluations; The safety profile will be assessed through the recording, reporting and analyzing of baseline medical conditions, adverse events, physical examination findings including laboratory tests.;Timepoint(s) of evaluation of this end point: Months: 0, 3, 6, 18; Months: 3, 6, 9, 12, 15, 18
