Safety and Efficacy of Intrathecal NTF001 Injection in ALS (NTF-ALS)

2026年5月25日 更新者:Ruijin Hospital

A Study of the Safety and Efficacy of Intrathecal NTF001 Injection in the Treatment of Amyotrophic Lateral Sclerosis

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.

詳細な説明

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.

実験的:Low-dose NTF001
Participants in this cohort will receive a single intrathecal administration of low-dose NTF001 (2E+14 vg)injection.
NTF001 is an investigational AAV-mediated gene therapy product designed to express human neuron-derived neurotrophic factor (NDNF). It will be administered once by intrathecal injection to patients with amyotrophic lateral sclerosis (ALS). Participants will receive NTF001 according to the assigned dose cohort and will be followed for safety, tolerability, and preliminary efficacy.
実験的:High-dose NTF001

メジャーの説明
時間枠
Change From Baseline in ALS Functional Rating Scale-Revised Score
時間枠:Baseline through Week 52
The ALS Functional Rating Scale-Revised (ALSFRS-R) will be used to assess functional status in patients with ALS. The total score ranges from 0 to 48, with higher scores indicating better functional status.
Baseline through Week 52
Change From Baseline in ALS Quality of Life Assessment
時間枠:Baseline through Week 52
Quality of life will be assessed using an ALS-specific quality-of-life questionnaire. Changes from baseline will be evaluated during the follow-up period, with higher or lower scores interpreted according to the scoring rules of the selected questionnaire.
Baseline through Week 52
Change From Baseline in ALSAQ-40 Score
時間枠:Baseline through Week 52
The Amyotrophic Lateral Sclerosis Assessment Questionnaire-40 (ALSAQ-40) will be used to assess disease-specific quality of life. The questionnaire evaluates multiple domains of daily functioning and well-being in patients with ALS, with higher scores generally indicating worse quality of life.
Baseline through Week 52
Change From Baseline in Norris Scale Score
時間枠:Baseline through Week 52
The Norris Scale will be used to assess neurological function and disease severity in patients with amyotrophic lateral sclerosis. Changes from baseline in the Norris Scale score will be evaluated during the follow-up period, with lower scores indicating greater functional impairment.
