DUAL GLP-1/GIP RECEPTOR AGONISTS THAT CAN CROSS THE BBB SHOW SUPERIOR NEUROPROTECTIVE EFFECTS (ADPD 2025) - "Methods Bydureon (exenatide) and Adlyxin (lixisenatide) showed disease-modifying protective effects in patients with PD in two phase 2 clinical trials...NLY01, a pegylated form of exenatide that can't cross the BBB did not show any effects in PD patients in a phase 2 trial...Results Currently, two phase 3 trials are ongoing, testing the diabetes drug Ozempic/Wegovy (semaglutide) in AD patients...In animal models of AD or PD, dual agonists were able to protect neurons better than GLP-1 class drugs such as liraglutide, semaglutide or tirzepatide that were designed to treat diabetes and that stay in the blood for longer periods. Conclusions The dual GLP-1/GIP receptor agonist KP405 (DA5-CH) is currently in a phase 1 clinical trial and Results will be shared at the conference."

Drug Development. (PubMed, Alzheimers Dement) - "The results demonstrate that enhanced BBB penetration of GLP-1 class drugs shows superior neuroprotective effects in a 3xtg mouse model of AD. This mirrors the observations from clinical trials in PD patients that show enhanced protection with drugs that can cross the BBB better."

The neuroprotective properties of GLP-1R agonists correlate with their ability to cross the blood-brain barrier (AAIC 2024) - "Exenatide and Lixisenatide both showed excellent protective effects in patients Parkinson's disease (PD) and both drugs can readily cross the BBB. Liraglutide showed limited effects and can only cross the BBB at a low rate. A pegylated form of exenatide NLY01 did not show any effects in a clinical trial and the drug does not cross the BBB... The results demonstrate that enhanced BBB penetration of GLP-1 class drugs shows superior neuroprotective effects in a 3xtg mouse model of AD. This mirrors the observations from clinical trials in PD patients that show enhanced protection with drugs that can cross the BBB better."

The Effects of NLY01, a Novel Glucagon-Like Peptide-1 Receptor Agonist, on Cuprizone-Induced Demyelination and Remyelination: Challenges and Future Perspectives. (PubMed, Neurotherapeutics) - "In summary, despite the promising anti-inflammatory and neuroprotective effects of GLP-1R agonists that have been previously described, our experiments provided no evidence to support a beneficial effect of NLY01 on limiting demyelination or enhancing remyelination. This information may be useful in selecting proper outcome measures in clinical trials of this promising class of drugs in MS."

D&D Pharmatech "Simultaneous clinical trials in the US" (Hankyung) - “Investors are paying attention to D&D Pharmatech because it has several new drug candidates that can work on the global stage. The best is 'NLY01', a brain disease treatment….D&D Pharmatech also challenged the Alzheimer's treatment market with the same substance. In the first half of next year, it plans to enter a phase 2 clinical trial targeting 540 patients. It also submitted a clinical trial plan to the FDA.”

Blocking microglial activation of reactive astrocytes is neuroprotective in models of Alzheimer's disease. (PubMed, Acta Neuropathol Commun) - "Our study indicates that the GLP-1 pathway plays a critical role in microglia-reactive astrocyte associated neuroinflammation in AD and the effects of NLY01 are primarily mediated through a direct action on Aβ-induced GLP-1R microglia, contributing to the inhibition of astrocyte reactivity. These results show that targeting upregulated GLP-1R in microglia is a viable therapy for AD and other neurodegenerative disorders."
