EMBO Molecular Medicine: Aivocode CAQK Tetrapeptide Reduces Brain Lesion Size and Inflammation in Mouse and Pig TBI Models, FDA IND Planned

An IQAC-CSIC, UC Davis, and Aivocode collaboration published in EMBO Molecular Medicine demonstrates that the four-amino-acid peptide CAQK, given intravenously after acute traumatic brain injury, homes specifically to a protein overexpressed in injured brain tissue and reduces lesion size, inflammation, and cell death. In mouse and pig TBI models, CAQK-treated animals showed lower expression of inflammatory markers and improved memory and behavioral test outcomes versus untreated controls, with no overt toxicity. Aivocode — a Sanford Burnham Prebys spin-out — has signaled it will seek FDA authorization to begin Phase 1 human trials. The work targets a market with no approved drug for stopping secondary TBI damage; Spain alone records about 100,000 TBIs annually.
