ION363 for ALS
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a new treatment called ION363 for individuals with a specific type of ALS (amyotrophic lateral sclerosis) linked to a genetic mutation called FUS. The researchers aim to determine if ION363 can improve patient function and extend life expectancy. Participants will receive either ION363 or a placebo (a substance with no active drug) to compare results. This trial may suit those with ALS symptoms and a confirmed FUS genetic mutation. As a Phase 3 trial, it represents the final step before FDA approval, offering participants an opportunity to contribute to potentially groundbreaking treatment advancements.
Will I have to stop taking my current medications?
The trial requires that participants taking edaravone, riluzole, Relyvrio, sodium phenylbutyrate, or tauroursodeoxycholic acid must be on a stable dose for at least 28 days before starting the study and continue on that dose during the study, unless a doctor advises otherwise. For other medications, they should be stable for at least 1 month before the study, but changes may be allowed with approval.
Is there any evidence suggesting that ION363 is likely to be safe for humans?
Research shows that ION363 has been tested in various settings, including the FDA's expanded access program. In these trials, several patients with ALS (amyotrophic lateral sclerosis) received this treatment. So far, results suggest that ION363 is generally well-tolerated.
For one patient with a specific ALS mutation, researchers administered repeated doses of ION363 through an injection into the spinal area. This method appeared to reduce levels of the harmful protein linked to the disease. While the treatment remains under study, these results are promising for safety.
ION363 is currently being tested in a later phase of clinical trials, which typically involves more participants and examines both safety and effectiveness. This indicates that earlier studies have already provided some evidence of safety. However, like any treatment, there might be risks, and ongoing research is essential to fully understand them.12345Why do researchers think this study treatment might be promising for ALS?
Unlike the standard treatments for ALS, which often focus on managing symptoms with medications like Riluzole and Edaravone, ION363 offers a novel approach by targeting the disease at a genetic level. Researchers are excited about ION363 because it is administered directly into the spinal fluid via lumbar intrathecal injection, potentially allowing for more direct and effective delivery to the central nervous system. This targeted approach could slow down the progression of ALS more effectively than current treatments, offering hope for improved outcomes in patients.
What evidence suggests that ION363 might be an effective treatment for ALS?
Research has shown that ION363, also known as jacifusen, might help treat ALS in people with specific changes in the FUS gene. Studies have found that ION363 can delay nerve cell damage in animals, suggesting it might slow the disease's progression in humans. ION363 reduces the production of harmful proteins from the FUS gene. Early results indicate that it is safe and could improve survival and function for those with this type of ALS. This trial will compare ION363 with a placebo to evaluate its effectiveness and safety, offering hope that ION363 could be an effective treatment option for patients with FUS-ALS.13456
Are You a Good Fit for This Trial?
This trial is for ALS patients with FUS mutations. Adults over 30 and children aged 12-65 can join if they meet certain disease progression rates and breathing capacity criteria. Participants must have stable medication use, a caregiver to report on their condition, and no recent participation in other trials or treatments like gene therapy.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- ION363
Trial Overview
The study tests ION363's effect on ALS symptoms and survival compared to a placebo. It aims to understand how the drug works in the body (pharmacokinetics) and its impact on the disease process (pharmacodynamics).
How Is the Trial Designed?

Treatment groups
Experimental Treatment
Placebo Group
ION363 will be administered by lumbar intrathecal (IT) bolus injection every 12 weeks, with an additional loading dose at 4 weeks, over a 60-week double-blind treatment period in Part 1; every 12 weeks for 84 weeks in the open-label extension treatment period (Part 2), with an additional loading dose administered 4 weeks after the first dose. Patients may continue to receive open-label ION363 every 12 weeks in Part 3 for up to 3 additional years or until ION363 becomes commercially available in the patient's country or until the Sponsor discontinues the development program, whichever occurs earlier.
Placebo will be administered by lumbar IT bolus injection every12 weeks, with an additional loading dose at 4 weeks, over a 60-week double-blind treatment period (Part 1).
