Tauroursodeoxycholic acid (TUDCA) is a hepatically-synthesized hydrophilic bile acid used for treatment of chronic cholestatic liver diseases. Experimental studies suggest that TUDCA may have cytoprotective and anti-apoptotic effects, with potential neuroprotective activity.
 
In this pilot study, 34 ALS patients were randomized to receive either TUDCA (1 g twice daily for 54 weeks) or placebo after a lead-in period of 3 months. The primary outcome measure was the proportion of patients with with improvement of at least 15% in the Amyotrophic Lateral Sclerosis Functional Rating Scale Revised (ALSFRS-R) slope during the treatment period as compared to the lead-in phase. Secondary outcomes included between-treatment comparison of ALSFRS-R at study end, comparison of the linear regression slopes for ALSFFRS-R mean scores, and the occurrence of adverse events.
 
The treatment group showed a higher proportion of responders compared to those who received placebo (87% vs. 43%, p = 0.021). At study end baseline-adjusted ALSFRS-R was significantly higher (P = 0.007) in TUDCA than in placebo groups. Comparison of the slopes of regression analysis showed slower progression in the TUDCA than in the placebo group (P < 0.01). TUDCA was well tolerated; there were no between group differences in adverse events.
 
Comment: This pilot study provides preliminary clinical data indicating that Tauroursodeoxycholic acid (TUDCA) is safe and may be effective in slowing the progression of ALS.
