The Spastic Paraplegia-Centers of Excellence Research Network (SP-CERN): Clinical Trial Readiness for Hereditary Spastic Paraplegia.

OBJECTIVES

The primary objective of this paper was to present the establishment of the Spastic Paraplegia-Centers of Excellence Research Network (SP-CERN) aimed at promoting clinical trial readiness for hereditary spastic paraplegia (HSP). SP-CERN is unique in its approach to addressing the diagnostic and therapeutic challenges associated with HSP through a large-scale, collaborative effort.

METHODS

Participants with HSP are identified through multicenter collaborations across 11 institutions in the United States. SP-CERN systematically collects longitudinal clinical data, biospecimens, and wearable device data from patients. Data are stored in a centralized REDCap database, facilitating shared access for analysis. Patients are evaluated using standardized assessment tools for motor function, biomarkers, and digital outcome measures.

RESULTS

SP-CERN has established a biorepository, centralized data collection methods, and standardized clinical assessments. It is conducting natural history studies for all HSP subtypes, enabling the validation of biomarkers and development of gene-based therapies.

DISCUSSION

SP-CERN's collaborative approach bridges gaps in clinical care and research for HSP by improving diagnostic capabilities and promoting clinical trial readiness. This initiative represents a framework for rare disease research, accelerating the development of novel therapies and improving patient outcomes through standardized, multi-institutional collaboration.
