International GNE Myopathy Patient Registry

August 13, 2026 updated by: Newcastle University

International GNE Myopathy Patient Registry (GNE001)

GNE myopathy, an ultra-rare disease, is a severe progressive myopathy that typically presents in early adulthood as weakness in the distal muscles of the lower extremities and progresses proximally, leading to a loss of muscle strength and function, and ultimately a wheelchair-bound state. The rate of progression is gradual and variable over the course of 10-20 years or longer.

There is a need to understand the world wide epidemiology of this ultra-rare condition, better understand a long-term disease course and the progression of disease-specific features, support translational research by evaluating burden illness and support clinical research recruitment. Therefore, the study will longitudinally collect information via an online patient registry platform.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

GNE myopathy is an ultra- rare condition. Most of the knowledge is coming from case reports or small cohort observations. There is a need to more precisely understand the long-term disease course and the progression of disease-specific features of GNE myopathy, and in turn characterise the overall burden of this illness. Also, to better understand the disease, describe it variability, genotype-phenotype correlation, quality of life, epidemiology, health-economics aspects and need for assistive walking devices. Collected data needs to be harmonised to be compatible collaborative work with Remudy (Japanese patient registry). This collaborative effort will enable the analysis of the largest GNE myopathy data set in the world. To this end, this study will collect patient information longitudinally. Upon patient's agreement, the registry curator can contact nominated clinicians to request additional data or data validation.

Study Objectives

The objectives of the study are to:

  • Longitudinally characterize disease-specific features of GNE myopathy
  • Characterize the burden of illness and quality of life in patients with GNE myopathy
  • Support recruitment in research activities
  • Inform registry participants via newsletters about scientific developments in the GNE myopathy field

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Must have a diagnosis of GNE myopathy (also known as HIBM, Quadriceps Sparing Myopathy (QSM), Inclusion Body Myopathy Type 2, distal myopathy with rimmed vacuoles (DMRV), or Nonaka disease)

Description

Inclusion Criteria:

  • Aged 18 years or older at the time of informed consent
  • Clinical and/or genetic diagnosis of GNE myopathy (also known as HIBM, QSM, Inclusion Body Myopathy Type 2, DMRV, or Nonaka disease)
  • Willing and able to provided electronic (or written) consent and comply with all study requirements.

Exclusion Criteria:

  • Under 18 years of age

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available.
