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.
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.

Incidence of adverse events and serious adverse events
Incidence of adverse events and serious adverse events within 570 days after treating SOD1 - ALS patients with RAG - 17 in the real world, and number of participants with treatment-related adverse events as assessed by Common Terminology Criteria for Adverse Events (CTCAE) V5.0.
Time frame: Baseline to 570 days
ALSFRS-R score
Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R) score (ALSFRS-R scores from 0 to 48, score decline indicates worse outcome of ALS patients, or disease progression and disability)

The level of SOD1 protein in cerebrospinal fluid
The level of SOD1 protein in the cerebrospinal fluid of ALS patients is positively correlated with the disease severity. Changes in the level of SOD1 protein in cerebrospinal fluid relative to the baseline at 60±3 days, 120±3 days, 180±3 days, 240±3 days, 300±3 days, 360±3 days, 450±3 days, and 540±3 days after treating SOD1 - ALS patients with RAG - 17 in the real - world setting
Time frame: baseline, 60±3 days, 120±3 days, 180±3 days, 240±3 days, 300±3 days, 360±3 days, 450±3 days, and 540±3 days
Plasma neurofilament light chain protein (NFL) level
The level of neurofilament light chain (NFL) in blood of ALS patients. Value increase indicates neuroinflammation or nerve damage. Changes in plasma neurofilament light chain protein (NFL) levels relative to the baseline at 60±3 days, 120±3 days, 180±3 days, 240±3 days, 300±3 days, 360±3 days, 450±3 days, and 540±3 days after treating SOD1 - ALS patients with RAG - 17 in the real world
Time frame: baseline, 60±3 days, 120±3 days, 180±3 days, 240±3 days, 300±3 days, 360±3 days, 450±3 days, and 540±3 days

Invasive mechanical ventilation
The time of occurrence of invasive mechanical ventilation after treating SOD1-ALS patients with RAG-17 in the real world
Time frame: From date of randomization until the date of first documented event about invasive mechanical ventilation. The assessment period is up to 30 months.
Gastrostomy
The time of occurrence of gastrostomy after treating SOD1-ALS patients with RAG-17 in the real world
Time frame: From date of randomization until the date of first documented event about gastrostomy. The assessment period is up to 30 months.
Death

Time frame: From randomization date to date of death from any cause. The assessment period is up to 60 months.
Muscle strength (MRC Scale)
Medical Research Council Scale (MRC Scale) is an assessment that is used to measure the change in muscle strength. MRC Scales ranges from grade 0 to grade 5, where grade 0 means no muscle contraction, grade 5 means muscle has full strength. Changes in muscle strength relative to the baseline at 60±3 days, 120±3 days, 180±3 days, 240±3 days, 300±3 days, 360±3 days, 450±3 days and 540±3 days after treating SOD1-ALS patients with RAG-17 in the real world
Time frame: baseline, 60±3 days, 120±3 days, 180±3 days, 240±3 days, 300±3 days, 360±3 days, 450±3 days and 540±3
ALSAQ-40
Change in Amyotrophic Lateral Sclerosis Assessment Questionnaire-40 (ALSAQ-40) score (from 40 to 200, score decline indicates worse outcome of ALS patients, or disease progression and disability). Changes in ALSAQ-40 relative to the baseline at 60±3 days, 120±3 days, 180±3 days, 240±3 days, 300±3 days, 360±3 days, 450±3 days, 540±3 days and 570±3 days after treating SOD1 - ALS patients with RAG - 17 in the real world
