That being said, I'm not as concerned as others about the relatively small difference, which was statistically significant, between the groups. Exenatide is believed to slow PD progression more so than reverse it. One year is not that much time in the normal progression of PD symptoms. Just think about how each of us vary from day to day. I don't think any of us would notice a two point UPDRS improvement or decline. I think the mild improvement in the test group compared to the mild deterioration in the placebo group is about all you could have hoped for over the course of one year. I also think that difference, along with the important DatScan results, is "indicative" of the drug effect being neuroprotective rather than just symptomatic. I would imagine that the Phase 3 trial, which will happen sometime in the future, will be longer term. It will probably be in the range of three years, like the design of the current ongoing Isradipine trial. Unfortunately, that's the time that is needed to see meaningful differences in progression compared to a placebo. Gary |

and just when you thought it was safe to get back in the water ...
A couple more exenatide write-ups! The SoPD blog has had another go at it, and the researchers have written an open-access editorial. Exenatide: An editorial | The Science of Parkinson's disease Is Exenatide a Treatment for Parkinson’s Disease? - IOS Press |

What is the relationship between alpha-synuclein and Exenatide?
Given the supposed centrality of alpha-synuclein in the pathogenesis of PD, you would expect any treatment which slowed the progression of PD to involve alpha-synuclein in some way. John

Quite a bit has happened since we last discussed exenatide.
This recent post on the SoPD blog can help bring us all up to date. :-) What do you do with a problem like Exenatide?: What do you do with a problem like Exenatide? | The Science of Parkinson's |

Thanks jeffreyn - it is fascinating and potentially important.
As an aside, one of my colleagues has spent a long time solving the structures of venom components and then testing them for possible clinical use - it is an important research area.

As well as discussing exenatide, the recent SoPD post also discusses research on another GLP-1 receptor agonist called NLY01. A recent AlzForum article also provides a good overview/discussion of this NLY01 research (IMHO).

A Phase 2 trial of another GLP-1 receptor agonist (liraglutide) is currently recruiting PwPs (Cedars-Sinai Medical Center, Los Angeles).
