Trial summary

Mucopolysaccharidosis type IVB (Morquio-B disease, MBD) is an autosomal-recessive lysosomal disease caused by mutations in a gene called GLB1. Clinically, Morquio B presents with progressive skeletal deformities involving mostly long bones and spine. Read more about this study

About this study

Official title: Natural History of Morquio B and Late-Onset GM1 Gangliosidosis

Mucopolysaccharidosis type IVB (Morquio-B disease, MBD) is an autosomal-recessive lysosomal disease caused by mutations in a gene called GLB1. Clinically, Morquio B presents with progressive skeletal deformities involving mostly long bones and spine. While the information on GLB1 mutations associated with MBD is limited, there is a significant overlap in clinical presentation between Morquio B and late-onset GM1 gangliosidosis with both conditions being caused by mutations in the same GLB1 gene. In this study, the investigators plan to collect retrospective data from patients' medical charts, as well as, information from the prospective follow up clinic visits. There will be two study visits with the interval of one year. The study procedures will include a detailed physical exam, bone scans, heart and lung function, physical endurance tests, hearing test, laboratory tests and quality of life surveys.

The purpose of this study is to collect data on the natural history of Morquio B and to create a biobank of laboratory samples (blood, urine and skin cells) for future research. This information will improve the understanding of the natural progression of Morquio B disease.

Read the detailed description

The primary objective of this study is to establish the natural history of Morquio B (Mucopolysaccharidosis type IVB, MBD) disease through the collection and analysis of retrospective and prospective data on patients diagnosed with Morquio B. Because of significant overlap in clinical presentation, patients with late-onset GM1 will also be included.

Upon consent, data from clinical, laboratory, functional and quality of life studies, and data from review of medical records will be collected and analyzed descriptively. In addition, the samples of blood, urine and fibroblasts will be collected and stored at BC Children Hospital Research Institute Biobank for future research. The prospective follow up will include two clinic visits, one year apart. The following data will be collected during the prospective observational part of the study (as per study protocol) and retrospective part (whether such data are available from the medical chart):

  • Medical history: Morquio B / Late-onset GM1 gangliosidosis diagnosis, presentation, treatments and symptom progression
  • Physical exam, including neurological and ophthalmological assessments
  • Standard Grip Strength Evaluation
  • Range of motion
  • Six-minute walk test (6MWT)
  • 3-Minute Stair Climb Test
  • Gait and Motion assessment
  • Pulmonary function testing
  • Hearing test
  • Echocardiography
  • EKG
  • X-ray (lumbar spine, upper \& lower limbs, hip)
  • DXA scan
  • Brain MRI
  • Laboratory tests (GAGs assay and pro-inflammatory cytokine panel)
  • Blood, urine and fibroblast samples for biobanking
  • Genetic test (if not done per standard of care)

Additional assessments and evaluations:

  • Patient-reported outcomes: quality of life SF-36, MPS HAQ and the interview on personally meaningful outcomes

Questions about this trial

What is this clinical trial studying?

An observational study of Morquio B Disease and GM1 Gangliosidosis Type III, run by University of British Columbia at 1 site in Canada.

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 3 inclusion and 5 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 30 Apr 2020. 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 Canada. 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 Nataliya Yuskiv, Dr (6048752000 ext. 6399, nyuskiv@cw.bc.ca), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Physical Development (time frame: Through study completion, an average of 1 year). The study lists 14 primary outcomes in all. 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 30 Apr 2020.
