Recent research suggests that a diabetes medication can potentially slow down the motor-related difficulties experienced by individuals with Parkinson’s disease, as indicated by findings published in the New England Journal of Medicine.
Affecting approximately 10 million persons globally, Parkinson’s is a debilitating affliction of the nervous system for which there is no known cure. The disorder manifests with symptoms such as tremors, lethargy in movement, difficulties with speech, and balance issues, all of which progressively worsen.
One avenue of research involves GLP-1 receptor agonists, a set of drugs that imitate a hormone found in the digestive tract and which are typically prescribed for the management of diabetes and obesity. These drugs are being explored for their potential neuron-protective properties.
Despite the intrigue, clinical benefits for Parkinson’s patients have thus far been nominal, with early-stage studies yielding inconclusive outcomes.
In the most recent study, a cohort of 156 individuals in the preliminary stages of Parkinson’s was assembled throughout France. Participants were then randomly assigned to either receive lixisenatide, marketed under Adlyxin and Lyxumia and produced by Sanofi, or a placebo.
After tracking the participants for one year, those who received the actual medication, administered by injection, witnessed no deterioration in their motor capabilities, unlike the placebo group.
The improvement in symptoms was qualified as “modest” in the study report and was primarily discernible through the professional assessment of participants engaged in various physical tasks. Olivier Rascol, a neurologist from Toulouse University and a primary author of the study, communicated to AFP that with an extended monitoring period, the manifested benefits may become more pronounced.
Rascol accentuated that this study notably demonstrates the medication’s impact on mitigating the progression of Parkinson’s disease, attributing this effect to its neuroprotective properties.
Reported Gastrointestinal Side Effects
Reported side effects from the medication predominately involved gastrointestinal issues like nausea, vomiting, and reflux, with some participants experiencing weight reduction.
Both Rasol and fellow researcher Wassilios Meissner, a neurologist from Bordeaux University Hospital, emphasized the necessity for further investigation to validate the drug’s safety and effectiveness prior to widespread patient use.
Michael Okun, the Parkinson’s Foundation’s medical director, shared with AFP that while the practical differences in patient outcomes were not particularly impactful, the statistical data and comparisons with other studies merit further consideration and inquiry.
“Experts will likely argue whether this study meets a minimum threshold for neuroprotection, and it likely does not,” articulated Okun, expressing concern regarding the observed weight loss in patients.
Neurology professor Rodolfo Savica from the Mayo Clinic in Minnesota remarked that the study hints at a potential therapeutic effect but reiterated the call for replication to substantiate the findings. He also suggested that further exploration into how separating patients by age might uncover the age brackets where the drug is more efficacious.
Anticipation is high for the outcomes of other imminent trials which may corroborate the results of this research.

FAQs about Diabetes Drug’s Effect on Parkinson’s Disease
- What is the drug mentioned in the study?
- The drug explored in the study is lixisenatide, marketed under the brand names Adlyxin and Lyxumia by Sanofi.
- What is the proposed benefit of this drug for Parkinson’s Disease?
- The benefit suggested by this research is the slowing down of motor symptom progression associated with Parkinson’s disease through what is thought to be a neuroprotective effect.
- What were the side effects experienced by those taking the medication?
- The main side effects included gastrointestinal problems such as nausea, vomiting, and reflux. A few participants also experienced weight loss.
- Is lixisenatide currently recommended for use in Parkinson’s patients?
- No, lixisenatide is not currently recommended for Parkinson’s patients as more research needs to be done to ensure safety and effectiveness.
- How significant were the study results?
- The study describes a “modest” improvement in symptoms. While statistically significant, these changes were not considered to have a remarkably noticeable clinical effect.
Conclusion
The study indicating that lixisenatide, a drug currently used for diabetes treatment, may slow the progression of Parkinson’s Disease motor symptoms is a hopeful breakthrough, marking a potential new avenue for therapeutic intervention. With notable cautionary advice from experts to replicate and further investigate the study’s findings before clinical application, the Parkinson’s community awaits additional research to unlock the drug’s full potential with eagerness. The ongoing battle against Parkinson’s may be far from over, but each scientific endeavor like this one sheds new light on possible pathways to ease the burden of the disease.
