Executive Summary

[GLP-1 receptor](/entities/glp1-receptor) agonists represent one of the most promising repurposing opportunities in neurodegeneration. Originally developed for type 2 diabetes, these agents have demonstrated neuroprotective effects through multiple mechanisms including enhanced insulin signaling, reduced neuroinflammation, mitochondrial protection, and synaptic plasticity support[@glp2023][@exenatide2022]. The class benefits from established safety profiles from diabetes indications, facilitating clinical translation.

The investment landscape for GLP-1 agonists in neurodegeneration is characterized by strong Big Pharma interest, active clinical development across Alzheimer's and Parkinson's diseases, and significant market potential. Key opportunities exist in biomarker development, combination therapies, and patient stratification strategies.

Market Overview

Current Market Size

The global GLP-1 receptor agonist market for diabetes is approximately $35 billion (2024), with neurodegenerative disease indications representing a potential $15-20 billion addition by 2030[@glp2024]. The expansion is driven by:

• Aging population demographics: Rising AD and PD prevalence globally
• Reimbursement pathways: Established pricing models for GLP-1 class in diabetes
• Disease modification potential: Unlike symptomatic treatments, GLP-1 agonists may slow disease progression
• Repurposing efficiency: Existing safety data reduces development costs and timeline

Therapeutic Approach

Mechanism of Action

GLP-1 receptor activation in the brain exerts neuroprotective effects through[@glp2023][@exenatide2022][@glp2023a]:

• Insulin sensitization: Addresses brain insulin resistance in AD
• Neuroinflammation reduction: Suppresses microglial activation
• Mitochondrial protection: Maintains neuronal energy metabolism
• Synaptic plasticity: Supports cognitive function
• [Autophagy](/entities/autophagy) promotion: Enhances clearance of protein aggregates

Competitive Advantages vs. Other Approaches

| Approach | Advantages | Disadvantages |
|----------|------------|---------------|
| GLP-1 agonists | Established safety, oral/injectable options, multi-mechanism | CNS penetration variable |
