Please see NCT #07054515 for information on the AZA-001-301 Master Protocol PRIMARY OBJECTIVE The primary objective of this study is to demonstrate superior efficacy on ataxic manifestations with oral nizubaglustat dosing compared with placebo when administered over 18 months in participants with late-infantile and juvenile forms of NPC disease SECONDARY OBJECTIVES I. To assess additional efficacy in ataxic and non-ataxic manifestations comparing nizubaglustat dosing with placebo when administered over 18 months in participants with late-infantile and juvenile forms of NPC disease II. To assess the pharmacokinetic (PK) properties of nizubaglustat after administration of the first dose (Visit 1) and at steady state after multiple once daily doses III. To assess the pharmacodynamic (PD) effects of nizubaglustat IV. To assess the safety and tolerability of daily oral nizubaglustat dosing compared with placebo, when administered over 18 months in participants with late-infantile and juvenile forms of NPC disease
