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.

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.

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,

The FDA approved an apomorphine hydrochloride infusion device (Onapgo) to treat motor fluctuations in adults with advanced Parkinson's disease, Supernus Pharmaceuticals announced on Tuesday. The wearable device is the first subcutaneous apomorphine infusion device for Parkinson's and provides continuous treatment during the day, Supernus noted.

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.
