Introduction to Bumetanide
Bumetanide is a loop diuretic commonly used to treat edema associated with congestive heart failure, nephrotic syndrome, and hepatic disease. Recently, it has been explored for its potential in treating autism spectrum disorder (ASD).
Clinical Trials Update for Bumetanide in ASD
Phase III Trials for ASD Treatment
Two significant phase III clinical trials, known as the SIGN 1 and SIGN 2 trials, were conducted to evaluate the efficacy and safety of bumetanide oral solution for treating ASD in children and adolescents. The SIGN 1 trial enrolled patients aged 7-17 years, while the SIGN 2 trial included younger patients aged 2-6 years. Both trials were randomized, double-blind, and placebo-controlled, with patients receiving bumetanide oral solution or placebo twice daily for a 6-month period[1][4].
Outcomes of the Trials
The primary endpoint of these trials was the change in the Childhood Autism Rating Scale 2 (CARS2) total raw score from baseline to Week 26. However, both studies were terminated early due to the absence of any significant difference between the bumetanide and placebo groups. The CARS2 total raw score decreased similarly in both the bumetanide and placebo groups, with no statistically significant difference observed. Additionally, no differences were found in secondary efficacy endpoints, including the Social Responsiveness Scale-2, Clinical Global Impression Scale, and Vineland Adaptive Behavior Scale[1][4].
Adverse Events
The trials also reported treatment-emergent adverse events that occurred more frequently with bumetanide than with placebo, including thirst, polyuria, hypokalemia, and dry mouth[1].
Future Directions
Despite the disappointing results, researchers suggest that it may be too soon to give up on bumetanide for ASD treatment. They propose that future trials should have stricter inclusion criteria and use methods like electroencephalography to identify participants who are more likely to respond to the drug. A study led by Hilgo Bruining used brain-wave markers to predict with 92% accuracy which participants would show a greater reduction in repetitive behaviors in response to bumetanide[4].
