Study 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 Niemann-Pick type C disease

Read the detailed description

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

Exclusion criteria

Exclusion Criteria:

  • A history of medical conditions other than NPC disease that, in the opinion of the Principal Investigator, would confound scientific rigor or the interpretation of results
  • Body weight of \<10 kg
  • The presence of another neurologic disease
  • The presence of moderate or severe hepatic impairment
  • The presence of moderate or severe renal impairment
  • count of \<100x10\^9/L
  • The dose of any anti-epileptic treatment(s) was not stable (required a change in dose within the previous 3 months) and/or a new anti-epileptic treatment (drug or procedure) was prescribed in the month before Baseline
  • Prior use of an drug within the 3 months before Screening; or prior participation in a clinical study involving gene therapy or stem cell transplantation within 2 years prior to Screening
  • A positive serum pregnancy test (for women of )
  • 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 before starting study medication
Terms in these criteria, in plain language(6)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Washout period

A planned gap after a treatment, so that its effects can lessen before the study treatment or a study assessment. Ask the study team and the doctor who prescribed it before changing any medicine.

What researchers measure

Primary outcomes

  1. 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)

    Time frame: Baseline to month 18

  2. 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

    Time frame: Baseline to month 18

Secondary outcomes

  1. Change from baseline in SARA score for gait/posture

    Assessed on a 9-point scale with higher scores indicating inability to complete the task

    Time frame: Baseline to months 6, 12, and 18

  2. Change from baseline in SARA score for speech

    Assessed on a 7-point scale with higher scores indicating unintelligible speech/anarthria

    Time frame: Baseline to months 6, 12, and 18

  3. Change from baseline in SARA score for kinetics

    Time frame: Baseline to months 6, 12, and 18

  6. Change from baseline in 9-Hole Peg Test (9-HPT-D)

    Assessed by the number of pegs per second placed in a 50-second, 9-HPT using the dominant hand

    Time frame: Baseline to months 6, 12, and 18

  7. Change from baseline in NPC-Clinical Severity Scale (NPC-CSS)

    Scores can range from 0 to 61, with a higher score indicating more severe clinical impairment

  8. Change from baseline in Goal Attainment scale (GAS)

    Assesses individual goals achieved during the study

    Time frame: Baseline to months 6, 12, and 18

  9. Change from baseline in Clinician Global Impression of Change (CGI-C)

    Assessed on a 7-point scale with higher scores indicating lower improvement

  13. Time-to-event comparison between nizubaglustat and placebo over the study duration for pre-defined detrimental events of an increase in functional SARA of ≥1.5 points

    Time frame: Baseline to month 18

  14. Time-to-event comparison between nizubaglustat and placebo over the study duration for pre-defined detrimental events of a decrease in PAS of ≥1 point

    Time frame: Baseline to month 18

  15. Time-to-event comparison between nizubaglustat and placebo over the study duration for pre-defined detrimental events of participants leaving the study due to participant/caregiver perception of disease progression/lack of efficacy

    Time frame: Baseline to month 18

  16. Maximum observed plasma concentration (Cmax)

    Time frame: Baseline and months 1,18, and 21
