Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 17 years and older
  • All sexes
  • No healthy volunteers
  • Child, Adult, Older adult

Who may be able to join

  • Individuals
  • Have provided informed consents (TCH and NIH) by subject or parent/legal guardian/legally authorized representative (as appropriate).
  • Are males or females ≥ 17 years of age at the time of screening
  • Have genetically confirmed diagnosis of syndromic CLN3 disease with
  • EITHER:
  • Two pathogenic mutations in the CLN3 gene, OR B. One confirmed pathogenic AND one variant of unknown significance, OR 2 variants of unknown significance, PLUS (+) secondary confirmation with evidence of characteristic inclusions on electron microscopy AND characteristic clinical course. There is no restriction on the specific CLN3 mutations for eligibility to enroll in the study. The mutations will be recorded in the electronic case report form (eCRF) for potential use in determining if CLN3 genotype is associated with tolerability and/or effectiveness of Beyond Batten Disease Foundation-1 (BBDF-1) (miglustat) therapy.
  • Male and female participants must use a highly effective method of contraception and must continue for the duration of the trial (and for 30 days after the end of treatment).
  • Are able to complete study assessments (subject or caregiver) and return to the clinic as scheduled

Who cannot join

  • Individuals
  • Have a medical condition that in the opinion of the PI would interfere with the safety assessments or increase the subject's risk of adverse events (AEs)
  • Use of any therapy (approved, off-label, or unapproved) intended to modify the course of any neuronal ceroid lipofuscinosis disease, including but not limited to flupirtine or flupirtine derivatives, cerliponase alfa (Brineura)
  • Have, in the opinion of the PI, a clinically significant abnormality in their clinical laboratory values (hematology, chemistry, or urinalysis) at screening that would preclude their participation in the study

About this study

Official title: An Open-label Safety, Pharmacokinetic, and Efficacy Study of the Combination of Miglustat for the Treatment of CLN3 Disease in Patients 17 Years of Age and Older

This is an open label study in approximately 6 subjects in 2 centers to assess the safety, PK, and efficacy of the maximum tolerable dose (MTD) of oral miglustat (100 mg once daily [QD] to 200 mg 3 times daily [TID]) in subjects ≥ 17 years of age with CLN3 disease over a period of 104 weeks.

Conditions

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Miglustat 100 milligrams (mg) Oral CapsuleDrug

    Subjects will initiate miglustat at Week 1 and dosing will be escalated until 600mg/d. If a subject has not reached the maximum dose (600 mg/d) by Week 8, the Week 8 dose will be subject's MTD.

Receives: Drug: Miglustat 100 milligrams (mg) Oral Capsule

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Treatment-emergent Adverse Events.

    Number of treatment-emergent adverse events (TEAEs) assessed at all visits and phone calls, with severity classified according to CTCAE v5.0

    Measured: 78 weeks

Secondary outcomes (6)
  1. Miglustat Pharmacokinetic (PK) Parameter Cmax

    Maximum plasma concentration Cmax

    Measured: 8 weeks

  2. Miglustat PK Parameter Tmax

    Time of Maximum concentration observed T max

    Measured: 8 weeks

  3. Miglustat PK Parameter Area Under Curve (AUC)

    Area under the plasma concentration versus time curve Area Under Curve from pre-administration to 8 hours post-administration (AUC0-8hour). Blood draws were taken at the following time points: pre-miglustat dose (0), 1, 2, 2.5, 3, 4, 6, and 8 hours after 8 weeks of treatment.

    Measured: 8 weeks

  4. Miglustat PK Parameter T1/2

    Miglustat elimination half life T1/2

    Measured: 8 weeks

  5. Clinical Efficacy Based on Unified Batten Disease Rating Scale Subscores

    Change from baseline of the modified Unified Batten Disease Rating Scale (UBDRS) Physical Assessment subscale (score from 0 to 112), specifically developed to assess motor symptoms in subjects with Batten Ceroid Lipofuscinosis, Neuronal 3 (CLN3) disease. Higher scores indicate more severe disease.

    Measured: 78 weeks

  6. Clinical Efficacy With the Seizure Frequency

    Seizure frequency were to be assessed using a seizure diary

    Measured: 78 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Miglustat 100 milligrams (mg) Oral Capsule in people with Batten Disease, run by Beyond Batten Disease Foundation at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 9 Sep 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 9 Sep 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Treatment-emergent Adverse Events. (time frame: 78 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Sep 2025.
