Plain-language summary
In this Phase 1 adult symptomatic patients with amyotrophic lateral sclerosis (ALS) carrying a superoxide dismutase 1 (SOD1) gene mutation thought to be causative of ALS, will receive single ascending doses of ARO-SOD1 administered by intrathecal (IT) infusion. The study is primarily intended to evaluate safety, but will also evaluate the effect of ARO-SOD1 on SOD1 cerebrospinal fluid (CSF) levels as a biomarker of pharmacodynamic (PD) effect, therefore lumbar punctures will be required at timepoints throughout the study. After each participant has completed their individual final visit, participants whose SOD1 CSF levels have recovered to a satisfactory level may rescreen and enroll into higher dose cohorts; or if unable or unwilling to rescreen may enroll into an open-label study to be added by amendment when supported by nonclinical data for multidose administration.

* Slow Vital Capacity (SVC) ≥ 50% of predicted value adjusted for sex, age, and height (from a sitting position) at Screening
* Body Mass Index (BMI) ≥ 18.0 kg/m2 at Screening
* Able to complete at least 6 months of follow-up

Males must not donate sperm and females must not donate eggs during the study and for at least 90 days following the end of the study or last dose of study drug, whichever is later.
Exclusion Criteria:
* Current or anticipated need of a diaphragm pacing system (DPS) during the study

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
