Brief Summary

An 18-month double-blind, randomized, placebo-controlled, multicenter, Phase 3 study to evaluate the safety and efficacy of oral nizubaglustat (AZ-3102) in late-infantile and juvenile forms of GM1 gangliosidosis or GM2 gangliosidosis

Conditions

Gangliosidoses, GM2; Gangliosidosis, GM1

Keywords

Nizubaglustat

Outcome Measures

Primary Outcomes (2)

• Change from baseline in total Scale for the Assessment and Rating of Ataxia (SARA) score

  Total SARA comprises eight categories with a cumulative score ranging from 0 (no ataxia) to 40 (most severe ataxia)

  Baseline to month 18

• Change from baseline in functional SARA score

  Functional SARA uses an abbreviated scale that scores 0 to 16, with higher scores indicating more severe impairment

  Baseline to month 18

Secondary Outcomes (20)

• Change from baseline in SARA score for gait/posture

  Baseline to months 6, 12, and 18

• Change from baseline in SARA score for speech

  Baseline to months 6, 12, and 18

• Change from baseline in SARA score for kinetics

  Baseline to months 6, 12, and 18

• Change from baseline in Vineland Adaptive Behavior Scale (VABS)

  Baseline to months 6, 12, and 18

• Change from baseline in Penetration-Aspiration Scale (PAS)

  Baseline to months 6, 12, and 18
