Interventional
Description of intervention(s) / exposure
Treatment: Drugs - SLS-005
Treatment: Drugs - Placebo

Experimental: SLS-005 0.75 g/kg Dose - SLS-005 (trehalose injection, 90.5 mg/mL for intravenous infusion). SLS-005 will be administered as a weight-based dose of 0.75 g/kg by IV infusion once a week.
For 52 weeks

Experimental: SLS-005 0.50 g/kg Dose - SLS-005 (trehalose injection, 90.5 mg/mL for intravenous infusion). SLS-005 will be administered as a weight-based dose of 0.50 g/kg by IV infusion once a week.
For 52 weeks

Placebo Comparator: Placebo volume equivalent to a SLS-005 0.75 g/kg dose calculation - Placebo (sodium chloride injection, 0.9, USP) will be administered by IV infusion once a week as a weight-based volume equivalent to a SLS-005 0.75 g/kg dose.
For 52 weeks

Placebo Comparator: Placebo volume equivalent to a SLS-005 0.50 g/kg dose calculation - Placebo (sodium chloride injection, 0.9, USP) will be administered by IV infusion once a week as a weight-based volume equivalent to a SLS-005 0.50 g/kg dose.
For 52 weeks

Key exclusion criteria
1. Any hereditary ataxia that is not genetically confirmed to be SCA type 3, or any type
of ataxia that is acquired or secondary to another medical condition including but not
limited to, alcoholism, head injury, multiple sclerosis, olivopontocerebellar atrophy,
multiple system atrophy, or stroke.

2. A score of 4 on any 1 of the 4 items that comprise the m-SARA.

3. Current participation in another clinical trial or completed participation in an
interventional trial less than 30 days prior to the screening visit (90 days for a
biological treatment).

4. Current diagnosis and/or healthcare professional-recommended treatment (medication
and/or diet) of diabetes mellitus type 1 or type 2.

5. Hemoglobin A1c (HbA1c) = 6.5% at the screening visit

6. Prior treatment with SLS-005, any other IV trehalose formulation, or known
hypersensitivity to trehalose.

7. Pregnant or breastfeeding.

8. History of alcohol or drug abuse within the last 2 years.

9. Chronic liver disease including Hepatitis B; Hepatitis C unless successful curative
treatment is documented; human immunodeficiency virus (HIV) infection.

10. Prior history of drug-induced liver injury (DILI) and/or laboratory results at
screening that indicate inadequate liver function (e.g., alanine aminotransferase
[ALT], aspartate aminotransferase [AST], gamma-glutamyl transferase [GGT] > 2 times
the upper limit of normal [x ULN] and/or total bilirubin level > 2 x ULN).

11. Laboratory results at screening that indicate inadequate renal function (e.g.,
estimated creatinine clearance of < 60 mL/min calculated by the Cockcroft and Gault
formula).

12. Any current cardiovascular disease or abnormality on 12-lead ECG at screening that, in
the investigator's opinion, is clinically significant and could be a potential safety
risk to the participant.

13. Any current psychiatric, neurological, or cognitive disorder that, in the
investigator's opinion, may interfere with the participant's ability to provide
informed consent or appropriately complete the study's safety or efficacy assessments.

14. Significant suicide risk as indicated by a "yes" response to question #4 or #5 under
Suicidal Ideation in the past 6 months or any "yes" response under Suicidal Behavior
in the past 3 years on the Columbia Suicide Severity Rating Scale (C-SSRS) during the
screening visit.

15. Any other medical condition or abnormal finding during screening that, in the
investigator's opinion, could confound collection or interpretation of safety or
efficacy data or be a potential safety risk to the participant
