Regarding the participants with MCI or AD, defined based on a clinical dementia rating (CDR) global score of 0.5 or 1, although the 18-month treatment with exenatide was safe and well-tolerated, it did not significantly affect clinical and cognitive measures, nor did it affect MRI cortical thickness and volume or most biomarkers in the cerebrospinal fluid (CSF), plasma, and plasma neuronal extracellular vesicles (EVs)

Mechanisms Under Investigation Current scientific literature suggests that Retatrutide may exert biological activity through mechanisms that include: Simultaneous activation of GLP-1, GIP, and glucagon receptors Modulation of integrated metabolic signaling pathways Influence on energy homeostasis regulation Interaction with endocrine feedback systems Participation in glucose and lipid metabolism pathways Regulation of appetite-related neuroendocrine signaling Many aspects of these mechanisms remain active areas of research and continue to be explored in experimental settings
