Официальное название

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 Niemann-Pick Type C Disease and in Late-infantile and Juvenile-onset Forms of GM1 Gangliosidosis or GM2 Gangliosidosis

Обзор

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 Niemann-Pick type C disease

Подробное описание

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
