The U.S. Food and Drug Administration on Tuesday approved a new drug for people who have a rare, inherited type of amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease.
The medication, toferson (Qalsody), targets a mutation in the SOD1-ALS gene. ALS attacks and kills nerve cells that control voluntary muscles. With ALS, patients lose nerve cells that affect chewing, walking, breathing and talking. The muscles weaken, and that leads to paralysis.
