STOP-HSP.Net: a Registry for Hereditary Spastic Paraplegia as an Integration Tool for Future Therapeutic Strategies

Overview

Our goal is to create a solid and harmonious disease registry of patient affected by hereditary spastic paraplegia (HSP) that facilitates the collection and management of patients' data over time encouraging the research and the development of future clinical trials. In-depth clinical phenotyping will develop significant clinical outcome measures that can be used in clinical trials and will allow the phenotypic complexity of the disease to be captured with the use of validated clinical scales, biomarkers and so-called patient reported outcomes (PROs).

The registry will involve five recruiting clinical centres (IRCCS Fondazione Stella Maris in Pisa, IRCCS Eugenio Medea in Conegliano, IRCCS Policlinico Gemelli in Rome, IRCCS Istituto di Scienze Neurologiche in Bologna, Università degli studi di Messina) and a data analysis partner (CINECA). Participants will be assessed annually at one of the five participating clinical sites. For each patient, at least one follow-up visit will be scheduled at an interval of 12 months in order to monitor and compare the longitudinal progression of HSP in similar groups (for example based on phenotype, age at onset, or genotype). At each visit all enrolled subjects will carry out a clinical-instrumental evaluation as per clinical practice, including: anamnestic collection, general and neurological objective examination; administration of illness scales (e.g. the SPRS scale) and quality of life questionnaires. Any biological samples will be collected as tissues, blood or urine and stored in the laboratories or bio-repositories of the individual centers and also reported in the electronic clinical report form (CRF) of STOP-HSP.net. The results of further diagnostic tests carried out such as Optical coherence tomography (OCT), brain magnetic resonance imaging (MRI) or neurophysiology performed during diagnostic practice or clinical follow up will also be collected. Any further clinical scales/evaluation questionnaires to be administered will be selected according to clinical need based on the neurological characteristics and genotype of each participant. All data relating to further instrumental and/or neurophysiological investigations carried out by the patient for clinical needs will also be collected. The data collected during the aforementioned clinical-instrumental-laboratory evaluations will be entered into the STOP-HSP.net register in pseudonymized form.
