Brief Summary

Multiple system atrophy (MSA) is a fetal, rare neurodegenerative disease presenting with parksinonism, autonomic dysfunction, and cerebellar ataxia. Numerous anti-parkinsonism agents have been developed. However, no medication has yet been proven effective for the symptomatic or even causative treatment in cerebellar ataxia. To our knowledge, cerebellar N-methyl-D- aspartic acid (NMDA) receptors play a special role in the modulation of motor learning and coordination. Tllsh2910, a NMDA modulator, has been found to attenuate the ataxic gait in the mouse model. Here, we designed a large-scale double-blind randomized controlled, cross-over phase III trial to investigate the efficacy of Tllsh2910 in neurodegenerative ataxic patients and the association of gut microbiota change.

Outcome Measures

Primary Outcomes (1)

  • =Scale for the assessment and rating of ataxia (SARA) score

    SARA is an 8-item performance based scale with gait, stance, sitting, speech disturbance, finger chase, nose-finger test, fast alternative hand movements, and heel-shin slide, yielding a total score of 0 (no ataxia) to 40 (most severe ataxia). The change in the SARA score will be recorded from period-level baseline to the end of the 12-week, 24-week, 36-week treatment period.

    Baseline, 12 weeks, 24 weeks, 36 weeks

Secondary Outcomes (6)

  • International Cooperative Ataxia Rating Scale (ICARS) score

    Baseline, 12 weeks, 24 weeks, 36 weeks

  • Unified multiple system atrophy rating scale (UMSARS) Part II score

    Baseline, 12 weeks, 24 weeks, 36 weeks

  • The composition change of gut microbiota

    Baseline, 12 weeks

  • The change of total time needed for a 8-meter walking test

    Baseline, 12 weeks, 24 weeks, 36 weeks

  • The change of the World Health Organization Quality of Life (WHOQOL-BREF) scale

    Baseline, 12 weeks, 24 weeks, 36 weeks

  • +1 more secondary outcomes
