Coya Therapeutics Inc. has unveiled promising findings from its research into COYA 303, an innovative biologic combination therapy incorporating LD IL-2 and a GLP-1 receptor agonist (GLP-1RA). The study, conducted on an in vivo lipopolysaccharide (LPS) mouse model of systemic and neuroinflammation, revealed significant therapeutic potential, particularly for conditions like Alzheimer's disease.

The initial animal cohort treated with COYA 303 demonstrated broad systemic and central immunomodulatory activity. This included a notable decrease in LPS-induced pro-inflammatory myeloid cells and associated cytokines, alongside an increase in beneficial anti-inflammatory immune cell subsets. Crucially, the therapy also led to a reduction in neuroinflammation within the brain's cortex and hippocampus. These compelling results highlight COYA 303's capacity to modify inflammatory pathways critical to neurodegenerative disease progression, reinforcing its continued development for conditions where chronic inflammation is a primary pathological driver. Previously, in vitro research indicated that combining LD IL-2 with a GLP-1RA synergistically boosts Treg numbers and function while diminishing pro-inflammatory activity.

Dr. Arun Swaminathan, Coya's CEO, expressed optimism regarding these initial positive signals. He emphasized the increasing recognition of GLP-1 receptor agonists as potential treatments beyond metabolic disorders, noting the strong interest generated by upcoming readouts for semaglutide in Alzheimer's disease. The company is actively pursuing further research with experimental cohorts 2 and 3 to evaluate modified treatment protocols, specifically focusing on the optimal timing of treatment initiation relative to the onset of inflammation.

These encouraging developments offer a beacon of hope in the fight against Alzheimer's and other neurodegenerative conditions. The potential of COYA 303 to not only mitigate inflammation but also enhance beneficial immune responses could pave the way for novel therapeutic strategies, underscoring a proactive approach to combating complex diseases through innovative scientific exploration and collaboration.
