Enrollment

21 participants

Start Date

Feb 4, 2026

Study Type

INTERVENTIONAL

Conditions

GM2 Gangliosidosis Niemann-Pick Type C Disease

Summary

This open-label study aims to gather long-term safety, tolerability, PK, biomarker, and clinical efficacy data relating to daily administration of Nizubaglustat in participants previously enrolled in the Phase 2 RAINBOW study (Cohort 1). In addition, the study aims to assess safety, clinical, and biochemical impact of transitioning NPC disease patients to Nizubaglustat after prior treatment with stable, full-dose Miglustat (Cohort 2).

Eligibility

Min Age: 12 Years

Inclusion Criteria10

Cohort 1 (NPC and GM2 patients):
Have been randomized into Phase 2 Study AZA-001-5A2-01.
OR
Cohort 2 (NPC patients):
Be male or female aged ≥12 years
Have a genetically-confirmed diagnosis of NPC disease
Have received full-dose Miglustat treatment for at least 12 months and experienced disease stabilization or worsening with treatment over the 2 previous clinic visits. Patients experiencing clinical improvement with Miglustat over the preceding 3 months should not be considered for this study.
Wish to change treatment to Nizubaglustat for their NPC disease.
Participants from Phase 2 Study AZA-001-5A2-01 (RAINBOW) who transitioned to Miglustat may be eligible for Cohort 2 if they meet all other criteria.
Participation is supported and deemed beneficial by the Principal Investigator. Be willing and able to be evaluated for all protocol assessments.
