The booming class of GLP-1 drugs that includes Ozempic and Wegovy is not only effective for diabetes and obesity, but is also showing early potential to help with conditions involving the brain, like mental health disorders, Alzheimer’s, and even, as new study results suggest — Parkinson’s disease.
In a Phase 2 trial, patients with early Parkinson’s disease taking an older GLP-1 diabetes drug called lixisenatide experienced no worsening of motor symptoms over a year, in contrast to patients on placebo who did, according to the study, published Wednesday in the New England Journal of Medicine.
The difference between the groups — as measured by a test looking at someone’s tremors and rigidity — was small, almost but not quite reaching what is deemed to be a clinically significant difference. Still, the authors said they were encouraged that patients on the drug did not get worse, and the findings add to a growing body of research that suggests this class of medications holds potential as a new way of addressing Parkinson’s, a slow-moving, debilitating disorder that currently lacks any treatments that can halt disease progression.
