Summary: The investigators conduct a prospective cohort study to explore the treatment effectiveness of continuous infusion of intrathecal baclofen (ITB) for hereditary spastic paraplegia (HSP) in China, delve into the optimal timing for starting treatment, and investigate the response differences among different subtypes. The ultimate goal is to provide clinical evidence and guidance for the application o...

Background: - Some nerve and muscle disorders that start early in life (before age 25), like some forms of muscular dystrophy, can run in families. However, the genetic causes of these disorders are not known. Also, doctors do not fully understand how symptoms of these disorders change over time. Researchers want to learn more about genetic nerve and muscle disorders that start in childhood by studying affect...

Summary: Hereditary Spastic Paraplegia (HSP) is a diverse group of genetic neurological conditions causing progressive weakness and spasticity in the lower limbs, severely reducing balance and gait capabilities. There is currently a lack of structured neurorehabilitation programs aimed at improving gait in adults with HSP. This protocol seeks to assess the feasibility and effectiveness of a structured trai...

Summary: The purpose of this study is to learn more about amyotrophic lateral sclerosis (ALS) and other related neurodegenerative diseases, including frontotemporal dementia (FTD), primary lateral sclerosis (PLS), hereditary spastic paraplegia (HSP), progressive muscular atrophy (PMA) and multisystem proteinopathy (MSP). More precisely, the investigator wants to identify the links that exist between the di...

Summary: 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...

Summary: The purpose of the HSP Sequencing Initiative is to better understand the role of genetics in hereditary spastic paraplegia (HSP) and related disorders. The HSPs are a group of more than 80 inherited neurological diseases that share the common feature of progressive spasticity. Collectively, the HSPs present the most common cause of inherited spasticity and associated disability, with a combined pr...

Summary: Patients will undergo a combined rehabilitation treatment consisting of 15 sessions on Lokomat and 15 sessions of physical therapy over three weeks for a total of 30 sessions. Two sessions/day for 5 days a week. The same subjects will conduct clinical-functional assessments before, at the end of treatment, and after a 3-month follow-up: 3D Gait Analysis with defined protocol (BTSBioenginner); Spas...

Summary: The Registry and Natural History Study for Early Onset Hereditary Spastic Paraplegia (HSP) is focused on gathering longitudinal clinical data as well as biological samples (skin and/or blood and/or saliva) from male and female patients, under the age of 30, who exhibited early onset symptoms of HSP with (1) a clinical diagnosis of hereditary spastic paraplegia and (2) the presence of variants in H...

Summary: 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 ...

Summary: 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 o...

Summary: Hereditary spastic paraplegia type 4 is the most frequent mutation of hereditary spastic paraplegias. It is commonly described as pure, with progressive weakness of the lower limbs, pyramidal syndrome and vesico-sphincter disorders. However, cognitive disorders have been reported for over 20 years, but remain poorly characterized.

Summary: To assess the safety and tolerability of single and multiple doses of MTR-601 in normal healthy volunteers under fed and fasted conditions. To evaluate the plasma and urine pharmacokinetics (PK) of MTR-601. To evaluate the pharmacodynamic (PD) effects of MTR-601 on muscle strength and muscle accumulation of MTR-601 by muscle biopsy and other potential mechanistic, predictive and PD markers of MTR-...
