About this trial
SPG56 is one of the complicated and early-onset HSP subtypes caused by genetic mutations in CYP2U1. So far, there is no standardized and specific clinical therapy for SPG56. The goal of this clinical trial is to explore the efficacy and safety of calcium folinate in the treatment of SPG56 patients.
This study is prospective, open-label and single arm and this trial will last for 6 years. A total of 10 patients will participate and they will receive calcium folinate treatment and professional clinical evaluation regularly.

Trial outcomes
Primary outcomes
GMFM-88
The change in the Gross Motor Function Measure-88 (GMFM-88) score from baseline (range: 0-264, higher scores mean a better outcome).
Secondary outcomes
SPRS score
The change in the Spastic Paraplegia Rating Scale (SPRS) score from baseline (range: 0-52, higher scores mean a worse outcome).
MMSE score
The change in the Mini-Mental State Examination (MMSE) score from baseline (range: 0-30, higher scores mean a better outcome).
Laboratory indicators
The change in the Laboratory indicators (blood biochemistry, lipid metabolism, folate, etc) and the number of participants with abnormal laboratory indicators.
Cranial CT/MRI
