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

StatusRecruitingThe study is currently enrolling participants. Only the study team can say whether a particular person can join.
Study typeInterventionalA study in which researchers assign participants to one or more interventions, such as a drug, procedure, device, behavioural programme or other approach, to measure their effects.
PhasePhase 3A later-stage study, usually with more participants, designed to give stronger evidence about how well a treatment works and how safe it is. It often compares the treatment with standard care or a placebo, and results may support an application for approval.

This is an 18-month, randomized, double-blind, placebo-controlled Phase 3 study of once-daily oral nizubaglustat in people with late‑infantile or juvenile‑onset Niemann‑Pick Type C disease. Participants are randomly assigned to nizubaglustat or matching placebo and monitored with neurological and functional assessments. The study collects safety data, drug levels, and measures of neurologic function over the treatment period.

What it is studying. The study tests whether daily oral nizubaglustat, compared with placebo, affects ataxic manifestations over 18 months in people with late‑infantile or juvenile NPC. It also evaluates other neurologic and functional outcomes, pharmacokinetics and pharmacodynamics, and the safety and tolerability of the drug.

What the researchers hope to learn. Primary scientific goal: compare nizubaglustat versus placebo on ataxic manifestations (measured by SARA) over 18 months. Secondary goals: assess additional ataxic and non‑ataxic clinical outcomes, seizure measures, pharmacokinetics and pharmacodynamics, biomarker changes, and safety/tolerability.

  • Current treatment with miglustat, provided the patient has been using the recommended dose for most of the past 12 months AND is, in the opinion of the investigator, satisfactorily treated with miglustat. Any participants receiving miglustat are required to undergo a 1-month washout period before starting study medication

Study description and what participation involves

The study's detailed description, as published on ClinicalTrials.gov.

Detailed description from the registry

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

Participants are randomly assigned, in double‑blind fashion, to take once‑daily oral nizubaglustat or matching placebo for 18 months. They will attend regular clinic visits for neurologic and functional tests (including SARA and other scales at baseline and at months 6, 12, and 18), complete questionnaires and goal assessments, keep a seizure diary, and provide blood samples for safety and drug‑level (PK/PD) testing (PK sampling is planned at baseline and at months 1, 18, and 21). Women of childbearing potential will have pregnancy testing and must follow contraceptive guidance; people on miglustat must complete a 1‑month washout before starting study medication.

How the study is structured. Participants are randomly assigned to one of two parallel groups: once-daily oral nizubaglustat dispersible tablets or matching placebo. The trial is double-blind (quadruply masked), so participants, caregivers, investigators, and outcome assessors do not know the assignment. Study visits include baseline and periodic neurologic and functional assessments (including SARA ataxia scoring), safety testing, and blood sampling for drug levels and biomarkers over the 18-month treatment period.

Questions you could ask

These questions are suggestions for a conversation with the study team or your own clinician, not advice.

  • Some participants receive a placebo. How is that decided, and what happens for placebo-group participants when the study ends?
  • The listed sites are in Argentina, Australia, Brazil, Canada, Germany, India, Italy, Mexico, Pakistan, Portugal, Spain, Switzerland, Turkey, United Kingdom, United States. Is any of them reachable for me, and does the study help with travel?
  • Which of the eligibility criteria would need to be checked with tests before I could join?

Terms used on this page · explanations by MedicalUpdates.ai

double-blind
Two types of people involved in the study do not know which intervention a participant is receiving. The ClinicalTrials.gov record specifies who is masked, for example participants, care providers, investigators or outcome assessors.
randomized
Participants are assigned to the study groups by chance, like a coin toss, rather than chosen by the doctor or the participant. This is done so the groups are comparable.
placebo-controlled
A study design in which one group receives a placebo so that the study treatment's effects can be compared with no active treatment.
informed consent
The process of explaining a study, including its risks and what participation involves, so that a person can decide freely whether to take part. Consent is usually documented in writing, and a participant can choose to leave the study later.
Baseline
Measurements taken at the start of the study, before any study treatment, so that later results can be compared with them.
childbearing potential
Studies often ask participants who could become pregnant, or could father a child, to use contraception during the study and for a period afterwards, because the effect of the treatment on a pregnancy is unknown.
Principal Investigator
The doctor or scientist responsible for running the study at a site or overall.
investigational drug
A treatment that is being tested and has not been approved for this use. It may be approved for a different condition. Being studied does not mean it works or is available outside the study.
before Screening
The checks done before enrolment to see whether a person qualifies, such as tests, scans or a review of medical history.
washout period
A period during which a participant stops a previous treatment before starting the study treatment, so the earlier treatment does not affect the results.
Inclusion Criteria
The conditions a person must meet to be considered for the study, for example a confirmed diagnosis, an age range or a test result.
Exclusion Criteria
The conditions that rule a person out even if they meet the inclusion criteria, for example other illnesses, certain medicines or pregnancy.
PRIMARY OBJECTIVE
The main result the study is designed to measure and report on. Other results, called secondary outcomes, are also collected.
placebo
A treatment that looks like the study treatment but contains no active ingredient. Some participants receive it instead of the study treatment, usually without knowing which they got.
pharmacokinetic
How the body absorbs, distributes, breaks down and removes a drug. It is studied by measuring drug levels or related substances at set times after a dose.
pharmacodynamic
What a drug does to the body, for example how it changes a blood marker or a symptom, and how that relates to the dose.
