They must not share study info on social media until the study ends. Excluded are those with certain genetic profiles, risks from lumbar puncture, previous oligonucleotide treatment or gene therapy, uncontrolled seizures, or other significant health issues.Check my eligibility
What is being tested?
The HALOS trial is testing ION582 given intrathecally (directly into the spinal canal) to see how safe it is and how well tolerated in different doses among participants with Angelman syndrome. The focus is on understanding the drug's effects and how it moves through and out of the body.See study design
What are the potential side effects?
While specific side effects aren't listed here, common ones related to intrathecal administration may include headache, back pain, nausea or vomiting. There could also be potential reactions at the injection site or systemic effects depending on how ION582 works in the body.
