Phase 2 RCT: Lixisenatide slows progression of motor disability in early Parkinson’s disease, but with notable gastrointestinal side effects
30 Apr, 2024 | 13:00h | UTCIn a phase 2, double-blind, randomized, placebo-controlled trial, the effect of lixisenatide, a glucagon-like peptide-1 receptor agonist, was evaluated for its potential to slow the progression of motor disability in patients with early Parkinson’s disease. A total of 156 patients, diagnosed within the past three years and stable on symptom-managing medications, were enrolled and equally divided into lixisenatide and placebo groups. After 12 months, the lixisenatide group showed a slight improvement in motor disability (−0.04 point change) compared to a worsening in the placebo group (3.04 point change) on the Movement Disorder Society–Unified Parkinson’s Disease Rating Scale part III. This difference was statistically significant (p=0.007). However, after a 2-month washout period, improvements were less distinct. Notably, 46% of lixisenatide-treated patients experienced nausea, and 13% reported vomiting. These findings suggest potential benefits of lixisenatide for motor symptoms in Parkinson’s disease, though further research is necessary to fully assess its efficacy and tolerability.
