TUDCA (tauroursodeoxycholic acid) is a small molecule that is being explored for its potential as a treatment for amyotrophic lateral sclerosis (ALS). TUDCA may decrease nerve cell death through its ability to act as an antioxidant that prevents toxic reactive oxygen from accumulating inside cells. There may also be an effect on immune function.
TUDCA-ALS is a randomized, double-blind, placebo-controlled study. This means the effect of TUDCA is tested by comparing a group of patients that receive TUDCA to a group of patients receiving a placebo-drug. Patients will be randomized to one of two treatment arms. During the study, both the patient as the research team do not know who is receiving placebo or TUDCA. This will help researchers to assess potential side- and treatment effects of TUDCA.
