About
This is a single-arm, open-label, early-phase clinical study designed to evaluate the safety, tolerability, and preliminary efficacy of intrathecal NTF001 injection, an AAV-mediated human neuron-derived neurotrophic factor gene therapy, in patients with amyotrophic lateral sclerosis (ALS).
12 patients with ALS will be enrolled. Each participant will receive a single intrathecal administration of NTF001 and will be followed for 52 weeks after treatment. The primary outcome measures include treatment-emergent adverse events (TEAEs) and serious adverse events (SAEs). Secondary outcome measures include changes in the ALS Functional Rating Scale-Revised (ALSFRS-R), quality-of-life assessments, and neurological function.
This study aims to provide preliminary clinical evidence regarding the safety and potential efficacy of intrathecal NTF001 injection in patients with ALS.
Full description
This is a single-arm, open-label, early-phase clinical study designed to evaluate the safety, tolerability, and preliminary efficacy of NTF001 injection in patients with amyotrophic lateral sclerosis (ALS). NTF001 is an investigational AAV-mediated gene therapy product designed to express human neuron-derived neurotrophic factor (NDNF). The investigational product will be administered once by intrathecal injection.
12 patients with ALS will be enrolled in this study. All eligible participants will receive a single intrathecal administration of NTF001 and will undergo scheduled safety and efficacy assessments during a 52-week follow-up period after treatment.
The primary objective of this study is to assess the safety and tolerability of intrathecal NTF001 injection, primarily by evaluating the occurrence of treatment-emergent adverse events (TEAEs), serious adverse events (SAEs), clinically significant laboratory abnormalities, vital signs, neurological examinations, and other safety-related findings.
The secondary objective is to explore the preliminary efficacy of NTF001 in patients with ALS. Efficacy assessments will include changes in the ALS Functional Rating Scale-Revised (ALSFRS-R), quality-of-life assessments, neurological function, and other exploratory clinical indicators.
This study is expected to provide preliminary clinical evidence regarding the safety, tolerability, and potential therapeutic effects of intrathecal NTF001 injection in patients with ALS, and to support further clinical development of AAV-mediated neurotrophic factor gene therapy for ALS.
