Brief summary
This is a Phase 1b, multicenter, randomized, placebo-controlled, double-blind study of 28 days, followed by an 18-month open-label extension, designed to evaluate the safety, pharmacokinetics (PK), and pharmacodynamics (PD) of DNL343 in participants with amyotrophic lateral sclerosis (ALS)
