Natural History Study for Pediatric Patients With Early Onset of Either GM1 Gangliosidosis, GM2 Gangliosidoses, or Gaucher Disease Type 2 (RETRIEVE)

November 5, 2021 updated by: Idorsia Pharmaceuticals Ltd.

This study is being conducted to better understand the natural course of GM1 gangliosidosis, GM2 gangliosidoses and Gaucher disease Type 2 (GD2). Information is planned to be gathered on at least 180 patients with GM1 gangliosidosis, GM2 gangliosidoses, and Gaucher Disease type 2. Retrospective data collection is planned for at least 150 deceased patients (Group A). Group B is for patients alive at the time of enrollment. In Group B it is planned to prospectively collect more comprehensive data from at least 30 patients. The purpose of this study is to collect relevant information for a adequate design of a potential subsequent research program in these diseases.

In this study no therapy is being offered.

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

1 second and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

This study will be conducted in hospitals/clinical centers managing pediatric patients with GM1 gangliosidosis, GM2 gangliosidoses, and/or Gaucher Disease type 2 across several countries in North America, South America, and Europe. In order to minimize the patient/data selection bias, the centers are asked to include all eligible patients from their center.

Description

Inclusion Criteria:

  • Patient with either GM1 gangliosidosis, GM2 gangliosidoses (Tay-Sachs, Sandhoff, or AB Variant), or Gaucher Disease Type 2.
  • Diagnosis confirmed by either biochemical (enzyme activity) or genetic testing, or both.
  • Date of birth on or after 1 January 2000.
  • Onset of first neurological symptom within 24 months of age.
  • Informed consent of parent or legal guardian as required by local law.

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.
Group A - Retrospective data collection
Participants with a confirmed diagnosis, either deceased patients or patients whose survival status is not known at enrollment.
Group B - Prospective data collection
Participants who are alive at enrollment. Data collection is retrospective for the time between birth and enrollment visit, and data collection is prospective from the enrollment visit onwards. Visits are performed as per local standard of care.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Survival of pediatric patients with early onset of GM1 gangliosidosis, GM2 gangliosidoses, and Gaucher Disease type 2
Time Frame: 2.5 years
2.5 years

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Epidemiological data available from medical records
Time Frame: 2.5 years
Patients' medical record data such as date of diagnosis, the date of appearance of first neurological symptom, dates of gain or loss of specific abilities (e.g. ability to sit) will be collected, if available.
2.5 years

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
July 31, 2019

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
October 30, 2021

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
