Inclusion Criteria4
- Male and female patients ≥18 years of age with Sporadic or familial ALS. In Part 1, patients must have a risk of ALS progression characterized by a European Network for the Cure of ALS (ENCALS) risk profile score ≥ -6 and ≤ -3.

- If taking riluzole, edaravone, and/or sodium phenylbutyrate and taurursodiol, must be on a stable dose prior to Screening. Sodium phenylbutyrate and taurursodiol are not permitted for patients enrolled in Part 2 of the study.
- Part 2 only: Patients with a pathogenic mutation in superoxide dismutase 1 gene (SOD1) must not be receiving treatment with tofersen or eligible for treatment with tofersen if available. Patients who have received prior treatment with tofersen and discontinued due to safety and/or efficacy reasons prior to Screening are eligible.
- Part 2 only: Use of ultra high-dose methylcobalamin for the treatment of ALS is permitted provided the patient has been on a stable dose for ≥11 weeks prior to the Day 1 visit.
