AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for adults with ALS caused by a change (mutation) in the SOD1 gene. It is the first test of the study drug ALN-SOD in people.
- Age
- 18 years or older
- Sex
- All sexes can join.
- Disease stage
- Weakness from ALS. Breathing capacity (slow vital capacity) of at least 50% of the predicted value. Body mass index of 35 kg/m2 or less.
- Earlier treatment
- If taking riluzole or edaravone, the dose must be stable for at least 4 weeks before the first dose. People who had tofersen in the last 6 months cannot join.
- Biomarker or test result
- A SOD1 gene variant that is known to be linked to ALS or is likely to cause ALS. Platelet count above 50,000/microliter.
Main reasons for not taking part
- Taking part in another interventional clinical trial
- Has had a tracheostomy
- Has dementia
- Uncontrolled psychiatric disease in the past 30 days
- Brain or spinal disease or injury that would interfere with the lumbar puncture, or an implanted CSF shunt or CNS catheter

- Original description
This study is researching an experimental drug called ALN-SOD (called "study drug"). This study is focused on people with Amyotrophic Lateral Sclerosis (ALS) caused by a change in a gene called the Superoxide Dismutase-1 (SOD1) gene. This type of ALS is known as "SOD1-ALS". This is the first time that ALN-SOD will be given to people.Read full original descriptionShow less
First in Human Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of Multiple Ascending Doses of Intrathecally Administered ALN-SOD in Participants With Amyotrophic Lateral Sclerosis and SOD1 Mutations
This study is researching an experimental drug called ALN-SOD (called "study drug"). This study is focused on people with Amyotrophic Lateral Sclerosis (ALS) caused by a change in a gene called the Superoxide Dismutase-1 (SOD1) gene. This type of ALS is known as "SOD1-ALS". This is the first time that ALN-SOD will be given to people.
The aim of the study is to see how safe and tolerable the study drug is.
The study is looking at several other research questions, including:
* The effect the study drug has on specific biomarkers, which are substances in the blood or in the fluid that surrounds the brain and spinal cord, known as Cerebrospinal Fluid (CSF) * How much study drug is in the blood and in the CSF, at different times * Whether the body makes antibodies against the study drug (which could make the drug less effective or could lead to side effects) * What effects the study drug has on ALS symptoms
Inclusion: Weakness attributable to ALS and a SOD1 variant that has been previously described as associated with ALS or is considered likely to cause ALS, as defined in the protocol; Slow Vital Capacity (SVC) ≥50% predicted value based on age, gender and height, measured in upright position; Body Mass Index (BMI) ≤35 kg/m2 at time of screening; If participants are taking riluzole or edaravone, they must be on a stable dose for at least 4 weeks prior to initial dosing visit and are expected to remain at that dose until the end of the study; Platelet count >50,000/microliter; Has normal blood pressure readings, as defined in the protocol.
Exclusion: Concurrent participation in another interventional clinical trial; Has received treatment with tofersen within 6 months prior to screening; NOTE: Other protocol defined inclusion / exclusion criteria apply; Has dementia, as assessed by the investigator; Has uncontrolled psychiatric disease, including psychosis, active or recent suicidal ideation, untreated major depression, in the past 30 days; Has a medical history of brain or spinal disease/injury that would interfere with the Lumbar Puncture (LP) process, CSF circulation or safety assessment, as defined in the protocol; Has had a tracheostomy; Presence of an implanted shunt for the drainage of CSF or an implanted Central Nervous System (CNS) catheter; Presents any concern to the study investigator that might confound the results of the study or poses an additional risk to the participant by their participation in the study; Was hospitalized (ie, >24 hours) for any reason other than ALS within 30 days of screening.
