About this study

The goal of this study is to assess the ability of MRI techniques to detect early stages of lipid accumulation in the liver of ASMD patients with the chronic visceral subtype compared to healthy subjects.

Participants will undergo an MRI with MR Spectroscopy (MRS) to measure lipid accumulation (steatosis) and MR Elastography (MRE) to measure liver stiffness (fibrosis).

Read the detailed description

Rationale: Acid sphingomyelinase deficiency (ASMD) is a rare lysosomal storage disorder caused by a deficiency of sphingomyelinase resulting in accumulation of the sphingolipid sphingomyelin (SM) in the liver, spleen and lungs. Accumulation of SM in the liver leads to liver fibrosis in a subset of ASMD patients. Enzyme replacement therapy (ERT, olipudase alfa, Sanofi Genzyme) is currently investigated in a phase 2/3 trial and recently received market authorization by the EMA and FDA. As ASMD is a slowly progressive disease, detection of early stages of SM storage in the liver might aid in identifying patients at risk for major complications who would benefit from therapy. Two magnetic resonance (MR) based techniques might be of interest: MR Spectroscopy (MRS) to measure lipid accumulation (steatosis) and MR Elastography (MRE) to measure liver stiffness (fibrosis).

Objective: To assess the ability of MRI techniques to detect early stages of lipid accumulation in the liver of ASMD patients with the chronic visceral subtype compared to healthy subjects.

Study design: Cross-sectional pilot study in which MRS and MRE measurements of ASMD patients will be compared to measurements in healthy subjects. All ASMD patients who participate will undergo an MRI during their yearly assessments. Patients eligible for therapy will also undergo an MRI after one year of treatment.

Study population: All adult patients with ASMD visiting the outpatient clinic for metabolic disorders of the Amsterdam UMC will be invited to participate. Participating ASMD patients will be matched to healthy controls based on age, sex and BMI in a ratio of 1:1.

Main study endpoint: Fat fraction in volume percentage (%) of liver tissue of ASMD patients measured with MRS compared to values of healthy subjects.

Nature and extent of the burden and risks associated with participation, benefit and group relatedness: The MRI procedure yields no risk: at most patients might feel uncomfortable lying in the tight space. Patients and healthy subjects will not directly benefit from participation in the study. The results of the study may improve clinical care in the future.

What participants receive

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

  • MR Spectroscopy (MRS)Diagnostic test

    MR Spectroscopy (MRS)

  • MR Elastography (MRE)Diagnostic test

    MR Elastography (MRE) with a device that induces shear waves in the body. This device is placed upon the abdomen of the subject and is hold in place by straps. The device will produce low-frequency vibrations (e.g. 30-60 Hz) which are not painful to the participant. A declaration of conformity and a safety document are provided in the study dossier.

What is being measured

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

  1. Fat fraction in volume percentage measured with MRS-PDFF

    Fat fraction in volume percentage measured with MRS-PDFF of ASMD patients compared to age-, sex, and BMI-matched healthy subjects.

    Measured: 1 year

Secondary outcomes (3)
  1. Liver stiffness in kPa measured with MRE

    Liver stiffness in kPa measured with MRE of ASMD patients compared to age-, sex, and BMI-matched healthy subjects.

    Measured: 1 year

  2. Correlations between fat fraction and/or liver stiffness and liver parameters

    Correlations between fat fraction and/or liver stiffness and liver parameters (i.e. liver stiffness measured with fibroscan, liver volume and plasma ALT and AST levels)

    Measured: 1 year

  3. Correlations between fat fraction and/or liver stiffness and general disease parameters

    Correlations between fat fraction and/or liver stiffness and general disease parameters (i.e. spleen volume, CO diffusion capacity, plasma LSM, LSM-509 and chitotriosidase levels)

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

A study testing MR Spectroscopy (MRS) and MR Elastography (MRE) in people with Asmd, Visceral Type, run by Eline C. B. Eskes at 1 site in Netherlands.

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 3 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: status not confirmed, as of the sponsor's last update on 15 Jun 2023. 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 Netherlands. 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.

Are results available for this study?

Results are not available in the source record.

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

Contact Eline CB Eskes, MD (0205669111, e.c.eskes@amsterdamumc.nl), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Fat fraction in volume percentage measured with MRS-PDFF (time frame: 1 year). 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 15 Jun 2023.
