NCT04399265

Brief Summary

This study evaluates the effectiveness of oral trehalose in alleviating the neuropathological and motor behaviour deficits among patients with SCA3. A total of 40 participants with SCA3 will be recruited, with 20 participants to be administered with trehalose while another 20 participants to be administered with a maltose placebo.

    Baseline, 3 months, and 6 months; as well as 3, 6, 9, and 12 months post-treatment follow-up.

  • Changes from Baseline Wechsler Adult Intelligence Scale (WAIS - 4) at 3 months and 6 months; as well as 3, 6, 9, and 12 months post-treatment follow-up.

    Baseline, 3 months, and 6 months; as well as 3, 6, 9, and 12 months post-treatment follow-up.

  • Changes from Baseline Delis-Kaplan Executive Function System (D - KEFS) at 3 months and 6 months; as well as 3, 6, 9, and 12 months post-treatment follow-up.

    Baseline, 3 months, and 6 months; as well as 3, 6, 9, and 12 months post-treatment follow-up.

  • +3 more secondary outcomes

Other Outcomes (4)

  • Changes from Baseline Structural / T1 MRI at 3 months.

    Baseline and 3 months

  • Changes from Baseline Situational Motivation Scale (SIMS) at 3 months and 6 months; as well as 3, 6, 9, and 12 months post-treatment follow-up.

    Baseline, 3 months, and 6 months; as well as 3, 6, 9, and 12 months post-treatment follow-up.

PARTICIPANT, OUTCOMES ASSESSOR
Masking Details
Patients with SCA 3 will be randomised into the active treatment group and placebo group to which they are blinded from their group allocation. Likewise, the outcome assessor will be blinded from the patient's group status. A partial unblinding will be made with Group A vs. Group B (rather than the actual grouping) for preliminary analysis on Visit 1 and Visit 2.

Intervention Model
PARALLEL
Model Details: This study will employ a double-blind randomised controlled trial (RCT) with two arms. Patients with SCA3 will be randomly allocated to oral trehalose group and a maltose placebo group. A total of 20 participants will be allocated to each group. There is a possibility of including other types of SCA at later stage of the study.
