Testing a new medication to slow muscle weakness in early ALS

This trial is testing a medication called pridopidine to see if it can help slow the progression of ALS (amyotrophic lateral sclerosis). About 500 people with early-stage ALS will participate. Half will receive the medication while the other third will receive a placebo (a pill with no active ingredient), and researchers will compare how each group progresses over time.

ALS is a serious disease that weakens muscles over time, and current treatments only help a little. Researchers hope this medication might slow down how quickly the disease progresses, giving people with ALS more time and better quality of life.
