This is a pilot, prospective registry study run by the Spastic Paraplegia - Centers of Excellence Research Network (SP-CERN). It aims to enroll about 100 people with genetically confirmed hereditary spastic paraplegia type 4 (SPG4) or type 5A (SPG5A) to create a shared clinical database and biobank. The pilot will also test standard outcome measures and harmonize procedures across sites to prepare for future research. No treatments are assigned in this observational study.

What it is studying. The study is collecting natural history data on SPG4 and SPG5A, storing blood and genetic samples, validating clinician- and patient-reported outcome measures and biomarkers, and testing procedures for a shared, harmonized research infrastructure.

What the researchers hope to learn. Establish a shared clinical database and biobank for SPG4 and SPG5A; harmonize outcome measures across sites; discover and validate biomarkers and patient- and clinician-reported measures; improve understanding of molecular causes to support development of future therapeutic targets and adequately powered clinical trials.

What this study is about

The study's own summary, as published on ClinicalTrials.gov. Underlined terms have a short explanation.

The Spastic Paraplegia - Centers of Excellence Research Network (SP-CERN) is a collaborative research consortium dedicated to advancing the understanding, diagnosis, and treatment of hereditary spastic paraplegia (HSP) and primary lateral sclerosis (PLS). Aims of the consortium are to a) perform natural history studies of HSP subtypes, b) discover and validate biomarkers and clinician- and patient-reported outcome measures, c) uncover HSP's molecular pathophysiology and develop rational therapeutic targets, and d) perform sufficiently powered clinical trials. The current pilot study is aimed at enrolling 100 individuals with hereditary spastic paraplegia type 4 (SPG4) or hereditary spastic paraplegia type 5A (SPG5A).

Study description and what participation involves

The study's detailed description, as published on ClinicalTrials.gov.

Show the detailed description from the registry

The hereditary spastic paraplegias (HSPs) include over 80 rare neurogenetic disorders, collectively representing the most prevalent cause of inherited spasticity and related disabilities globally. In all forms of HSP, there is a progressive deterioration of the long axonal tracts, resulting in substantial motor dysfunction and various other symptoms. Primary lateral sclerosis (PLS) is a related, degenerative neurological disorder characterized by the progressive deterioration of upper motor neurons. Both conditions result in muscle weakness and spasticity, with significant morbidity and impact on quality of life. The Spastic Paraplegia - Centers of Excellence Research Network (SP-CERN) is a collaborative research consortium dedicated to advancing the understanding, diagnosis, and treatment of hereditary spastic paraplegia (HSP) and primary lateral sclerosis (PLS). SP-CERN provides a registry and natural history study across the whole age span, a biobank, and a genome archive. This will set the stage for a multitude of opportunities for improved diagnosis and trial readiness. A second objective is to harmonize this effort with similar consortia, especially in Europe, in addition to Asia, South America, and Africa, to help accelerate basic and clinical research on HSP and PLS on a global level. In summary, SP-CERN will support critical research infrastructure for collaborative high-quality research on HSP and PLS in North America and beyond. General aims include: A. Establish a shared clinical database, a repository of biospecimen samples, and a central database for the storage of all genetic data in SP-CERN. B. Synchronize and harmonize collaborations between institutions, clinical sites, and international collaborators through the development of a central research protocol in order to standardize outcome measures and maximize the quality of research and data to ensure clinical trial readiness by regulatory standards. C. Build comprehensive programs for advancements in diagnosis, provide more opportunities for innovative treatments, and increase access to high-quality healthcare for HSP and PLS patients. Specific aims for this first pilot study are: 1a. Enrollment of 100 individuals with genetically-confirmed hereditary spastic paraplegia type 4 (SPG4) or hereditary spastic paraplegia type 5A (SPG5A) in the shared clinical database. 1b. Biobanking of blood samples from 100 individuals with SPG4 or SPG5A in a shared biobank.

AI summaryWhat participation may involve, in plain languageShow ▾Hide ▴

AI-written from the registry record, not the study's own wording. May contain errors or omissions. Check the registry text on this page and the original record ↗ before acting on it.

If you join, you'll be entered into a shared clinical database and followed as part of a natural-history pilot for about 2 years. You will be asked to give blood samples for a biobank and to allow genetic data to be stored in a central genome archive. Study staff will collect clinical information and may ask you to complete clinician- and patient-reported outcome measures or other standard assessments. The registry does not list other specific procedures.

How the study is structured. This is a prospective, observational cohort (registry) pilot. Participants provide clinical information and blood samples; their data and samples are stored in a central database and biobank. The project follows participants and collects data over a two-year pilot period to standardize measures and prepare for larger studies. No experimental treatments are given.

Questions you could ask

These questions are suggestions for a conversation with the study team or your own clinician, not advice.

  • This is an observational study, so the study itself gives no treatment. What would taking part involve for me, and would it change my usual care?
  • The listed sites are in United States. Is any of them reachable for me, and does the study help with travel?
  • Which of the eligibility criteria would need to be checked with tests before I could join?

natural history
A study that follows how a condition changes over time without assigning an experimental treatment. It may involve study visits and tests, and is often used to plan future trials.
biomarkers
Something measurable in the body, such as a blood test result or an imaging finding, that indicates how a condition or treatment is behaving.
outcome measures
Something the study measures to judge its results, such as a symptom score, a blood test or survival. Outcomes are grouped as primary, secondary and sometimes exploratory.
Inclusion Criteria
The conditions a person must meet to be considered for the study, for example a confirmed diagnosis, an age range or a test result.
Exclusion Criteria
