The study may suggest that other researchers should be less optimistic about the prospects for treating a range of other conditions with newer weight-loss drugs.

The GLP-1 receptor agonist exenatide failed to meet its primary outcome in a phase III trial of Parkinson's disease patients. Weekly injections of the GLP-1 receptor agonist exenatide (Byetta, Bydureon) did not slow Parkinson's disease progression or improve symptoms, the phase III Exenatide-PD3 trial showed.

A drug for treating diabetes similar to popular weight-loss medicines such as Ozempic did not show any benefits for people with Parkinson’s disease, according to a new study. Researchers conducted a double-blind,

WEDNESDAY, Feb. 5, 2025 (HealthDay News) -- Hopes that GLP-1 drugs such as Ozempic and Wegovy could help slow Parkinson's disease have taken an hit. A new study found that a drug in the same class called exenatide, marketed as Byetta, had no effect on slowing the disease or easing its symtoms.

Treatment with exenatide, a GLP-1 receptor agonist, was comparable to placebo in slowing the rate of Parkinson’s disease progression over 96 weeks of treatment, according to a phase 3 study published in The Lancet.

The GLP-1 drug, exenatide, has no positive impact on the movement, symptoms or brain imaging of people with Parkinson's, finds a new study led by UCL researchers.
