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 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Males or females age 18 years or older in whom the diagnosis of X-ALD has been confirmed by VLCFA assay and/or mutation analysis.
  • Clinical evidence of spinal cord involvement with EDSS score between 1 and 6.5. Patients with an EDSS score of 6.5 are severely affected but have retained the capacity to walk 20 meters with the aid of a walker, crutch, or two canes.
  • Either a normal brain MRI, or a type 3 pattern of MRI abnormality in which the abnormality is considered to represent the centripetal extension of the distal axonopathy.
  • Adrenal function assessed by measurement of plasma ACTH and appropriate steroid replacement if adrenal insufficiency is present.

Who cannot join

  • Kurtzke EDSS score of >6.5.
  • Cognitive or behavioral abnormalities that impair capacity to give informed consent or carry out procedures that form part of the protocol.
  • Current use, or use within 3 months, of Lorenzo's oil or other therapies that may alter the course of X-ALD. Bone marrow transplant will be a permanent exclusion criterion.
  • Contraindications for MRI procedure such as subjects with paramagnetic materials in the body, such as aneurysm clips, pacemakers, intraocular metal or cochlear implants.
  • Subjects who are pregnant.
  • Allergies to peppermint
  • Presence of non-specific conditions that may interfere with clinical assessment or participation in the protocol.

About this study

Study of the use of Lorenzo's oil in adults with adrenomyeloneuropathy, the adult form of Lorenzo's oil.

Read the detailed description

This is a double-masked placebo controlled study of glyceryl trioleate-glyceryl trierucate (Lorenzo's Oil (LO)) therapy in adrenomyeloneuropathy (AMN), the adult form of X-linked adrenoleukodystrophy (X-ALD). AMN is a slowly progressive distal axonopathy that involves the long tracts of the spinal cord and differs from the rapidly progressive inflammatory cerebral forms that most commonly affect boys and adolescents. All forms of X-ALD are associated with the abnormal accumulation of very long chain fatty acids (VLCFA) in plasma and tissues. The oral administration of LO normalizes plasma VLCFA levels within 4 weeks. While previous therapeutic trials of LO therapy in patients with the cerebral forms of X-ALD have been disappointing, recent studies suggest that it is beneficial in two types of X-ALD: 1) as a preventive of neurological involvement in asymptomatic boys; and 2) in AMN, where it appears to slow the rate of progression. None of the previous studies have been controlled, and we are now conducting the first placebo-controlled trial.

The 4-year study will include 120 men with AMN who do not have evidence of cerebral involvement, and 120 women who are heterozygous for X-ALD and have an AMN-like syndrome. The rate of progression will be compared in the LO and placebo groups using the Kurtzke EDSS score as the primary outcome and a variety of secondary outcomes.

Adrenomyeloneuropathy affects about 1 in 40,000 men and 1 in 30,000 women. It is a progressive disorder that leads to inability to walk and other severe deficits. This study will provide definitive information whether Lorenzo's Oil therapy can slow progression.

What participants receive

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

  • Lorenzo's oilDrug

    4:1 glyceryl trioleate-glyceryl trierucate (Lorenzo's oil)given orally, daily as approximately 10% of nutritional calories with supplementation.

What is being measured

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

  1. Clinical Progression of the disorder

    Measured: 48 months

Secondary outcomes (1)
  1. Determine the degree to which newly developed methods to assess spinal cord function and structure in adrenomyeloneuropathy, namely quantitative sensorimotor tests and spinal cord imaging, can act as early surrogate markers of disease progression.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Lorenzo's oil in people with Adrenomyeloneuropathy and Adrenoleukodystrophy, run by Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) 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 4 inclusion and 7 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: stopped early, as of the sponsor's last update on 2 Mar 2012. 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 phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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

Are results available for this study?

The study was stopped early (reason given: Upon recommendation of DSMB). Results are not available in the source record.

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?

Clinical Progression of the disorder (time frame: 48 months). 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 2 Mar 2012; AzTrials last refreshed its copy on 8 Nov 2026.
