Overview investigating the effect of extended-release exenatide (Bydureon) injections versus placebo on progression of disease, non-motor, and motor symptoms. A second phase 2 study in South Korea is studying the effect of Peptron's novel sustained release formulation of Exenatide, PT320, on motor function.

[P3, UCL] important, Exenatide-PD3, ISRCTN14552789, NCT04232969,
Estimated Study Completion Date : July 31, 2024


PROTOCOL: (Vijiaratnam, 2021 #2793)
Sse:
The sample size is based on the detectable effect size (primary outcome is the MDS-UPDRS motor subsection in the OFF medication state) for a two-arm (exenatide vs placebo) parallel-group trial design. The calculations assume a common SD of 13.5, and a correlation of 0.70 between baseline and follow-up MDS-UPDRS measurements. These estimates are reasonable based on data from the previous exenatide-PD trial.14 On this basis, 160 evaluable participants divided equally between the two groups is sufficient to detect a difference of 5.0 MDS-UPDRS part 3 points in the OFF medication state between the two groups adjusting for baseline MDS-UPDRS part 3 OFF scores, with 90% power and at a significance level of 0.05. Assuming 20% attrition (withdrawal/lost to follow-up), 200 participants will be recruited.

Neuraly (D&D Phamatech)'s NLY01, is in a p2 clinical trial. This novel pegylated form of exenatide will be compared to placebo to assess its safety, tolerability, and efficacy in PD. (NCT04154072, N=240, recruitment to finish by end of the 2021 year); (cf: would like to start AD study (IND cleared, Phase 2b study), N=518):
Based on previous blind data analysis (UPDRS Part 3 and Part2+3 with 157 patients), we are very much convinced of a high probability of success in this ongoing Ph2 study.

- lixisenatide, liraglutide, and semaglutide are being studied in phase 2 placebo-controlled trials to assess the drugs' effects on motor outcomes in PD (studied by Toulouse University Hospital with Sanofi, Cedars-Sinai Medical Center with Novo Nordisk, and Oslo University Hospital, respectively). The trials of these three re-purposed compounds all involve early-stage PD, with the primary outcome measure of change in motor function from baseline to trial end-point.
- These four p2 studies vary in their treatment duration; the study of semaglutide is the longest with 4 years of treatment, with 13.5 m for the study of liraglutide, 12m study of lixisenatide, and 9 m for the Neuraly study of NLY01. The lixisenatide study is unique amongst these four trials in that it has a washout period of 2 m after the 12-m treatment phase.

https://papers.ssrn.com/sol3/papers.cfm?abstract_id=4212371 liraglutide 1.2 or 1.8 mg SC daily, RCT, 52W, 2:1 randomization, Sixty-three subjects were enrolled and randomized to liraglutide (n=42) or placebo (n=21). There were 12 early withdrawals (9 liraglutide, 3 placebo), 4 of whom completed week 28 endpoint assessments. At 54 weeks, NMSS scores had improved by 6.6 points in the liraglutide group and worsened by 6.5 points in the placebo group, a 13.1 point adjusted mean difference (p <0.05). MDS-UPDRS part III and MDRS-2 score changes did not significantly differ between liraglutide and placebo. Secondary outcome analyses revealed a significant improvement of MDS-UPDRS part II (p=0.001), PDQ-39 (p<0.001), and Parkinson's Anxiety Scale Avoidance Behavior scores (p <0.05) in the treatment group. MDRS-2 sub-scores did not further differentiate study groups, while Delis-Kaplan Executive Function System letter fluency scores favored placebo group (p <0.05).
