Studying early signs of hereditary spastic paraplegia in at-risk individuals

Studying the Prodromal and Early Phase of Hereditary Spastic Paraplegia Type 4 (SPG4)

Not applicable Interventional University Hospital Tuebingen · NCT03206190

This study is trying to find early signs of hereditary spastic paraplegia in people who might be at risk, to better understand how the disease develops before symptoms show up.

What this trial studies

This study aims to collect prospective longitudinal data on the natural progression of hereditary spastic paraplegia type 4 (SPG4) in presymptomatic mutation carriers and those in the early stages of the disease. It will utilize various interventions, including clinical assessments, cognitive testing, lumbar punctures, blood draws, MRI scans, and electrophysiological evaluations to identify biomarkers that provide objective measures of disease activity. The goal is to better understand the disease before clinical symptoms appear and to track its early progression.

Who should consider this trial

Good fit: Ideal candidates include first-degree relatives of SPG4 patients or symptomatic individuals with a known SPAST mutation, aged 18 to 70 years.

Not a fit: Patients without a known SPAST mutation in their family or those with manifest spastic gait may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to earlier diagnosis and intervention strategies for individuals at risk of developing hereditary spastic paraplegia.

How similar studies have performed: While there have been studies on hereditary spastic paraplegia, this specific approach focusing on presymptomatic carriers and early biomarkers is relatively novel.
