• A rigorous 96-week Phase 3 trial involving 194 Parkinson's patients across six UK hospitals found that exenatide, a GLP-1 drug related to Ozempic, showed no benefit in treating or slowing disease progression.
• The double-blind study, led by UCL researchers, revealed no improvements in patient movements, symptoms, or brain imaging results, despite earlier smaller studies suggesting potential benefits.
• The disappointing results represent a setback for the half million Americans with Parkinson's disease, who currently have treatments for symptoms but no options to slow disease progression.
