简要总结
This study primarily evaluates the safety, tolerability, and efficacy of RAG - 17 in adult ALS patients with SOD1 - mutated genes in the real - world setting.
详细描述
Based on the results of the previous investigator - initiated trial (IIT) of RAG - 17 in the treatment of SOD1 - ALS, this study further planned to conduct another small - sample real - world research. By administering regular and quantitative intrathecal injections of RAG - 17 to subjects who meet the inclusion criteria of the study, the safety, tolerability, and efficacy of RAG - 17 in adult ALS patients with SOD1 - mutated genes in the real - world setting will be evaluated.

入选标准
- •18 ≤ Age ≤ 75 years old, regardless of gender.
- •ALS patients with confirmed SOD1 gene mutations (known SOD1 mutation sites with reported relevant disease progression).
- •The diagnosis meets the criteria for definite or probable familial or sporadic ALS in the El Escorial diagnostic criteria for amyotrophic lateral sclerosis revised by the World Federation of Neurology.
- •The patient himself/herself or their legal representative clearly understands, voluntarily participates in this study, and signs the informed consent form.
排除标准
- •Patients with SOD1 mutation sites occurring at nucleotides 44 - 66 (counting from the start of SOD1 protein translation) and patients with P.F21C mutation.
- •Patients diagnosed with other mental illnesses according to the DSM - V diagnostic criteria, or those with obvious suicidal intent.
- •Patients with severe hepatic insufficiency, severe renal insufficiency, or severe cardiac insufficiency. (Severe hepatic insufficiency refers to an ALT value ≥ 2.0 times the upper limit of normal or an AST value ≥ 2.0 times the upper limit of normal; severe renal insufficiency refers to a CRE ≥ 1.5 times the upper limit of normal or an eGFR < 40 mL/min/1.73m²; severe cardiac insufficiency refers to a NYHA score of 3 - 4.)
- •Patients with a history of alcohol or drug abuse.
- •Pregnant, lactating patients, those with a possibility of pregnancy, or patients planning to become pregnant.
- •Patients who have received any vaccination within 28 days.
- •Patients who are unable to cooperate with the follow - up for other reasons.
研究组 & 干预措施
Treatment Group
Patients who meet the inclusion and exclusion criteria are required to come to the hospital at the following time points to complete the intrathecal bolus injection of quantitative RAG - 17, relevant examinations, and evaluations by the research physicians: baseline, 60 ± 3 days, 120 ± 3 days, 180 ± 3 days, 240 ± 3 days, 300 ± 3 days, 360 ± 3 days, 450 ± 3 days, 540 ± 3 days. An online follow - up will be conducted at 570 ± 3 days.
干预措施: A sterile aqueous solution of RAG - 17 preparation (sodium salt) (Drug)
结局指标
主要结局
Incidence of adverse events and serious adverse events
时间窗: Baseline to 570 days
