Patients with amyotrophic lateral sclerosis (ALS) have a median survival of 2 to 5 years. There are 3 FDA-approved drugs for ALS (riluzole, edaravone and Relyvrio [phenylbuturate/taurursodiol]), but they only lead to modest benefit. There are several pathways involved in the disease, but all of them lead to neuroinflammation.
