Seurat Therapeutics, Inc. (Seurat) announced today the publication of preclinical studies of its lead product candidate, intranasal insulin-like growth factor-1 (IGF-1), in a rat model of migraine headaches, in the scientific journal Brain Research. The studies were conducted in Dr. Richard Kraig's laboratory at the University of Chicago. Seurat is the world-wide licensee of patents for nasal IGF-1 treatment of migraine headaches from the University of Chicago.
The publication reports that trigeminal pain pathway activation is significantly reduced after intranasal IGF-1 treatment. The studies demonstrated that oxidative stress increases calcitonin gene-related peptide (CGRP) expression, a trigeminal system pain pathway mediator associated with migraine; and that intranasal IGF-1 significantly reduces oxidative stress levels and trigeminal ganglion CGRP. This beneficial effect was not associated with hypoglycemia, which can occur with systemic administration of IGF-1. These findings support that intranasal IGF-1 has a unique potential to safely prevent migraine headaches through multiple novel mechanisms.
Further studies and clinical trials will be needed to validate this observation in humans, but we are enthusiastic about the results." Yuan Zhang, Ph.D., M.S., CEO of Seurat
IGF-1's therapeutic effects involve reducing oxidative stress and the amount of CGRP, which are known to be involved in human migraine headaches. This suggests that IGF-1 alone or in combination with other ant-CGRP agents may provide better migraine relief, something we are actively testing in the lab." Richard Kraig, M.D., Ph.D., the William D. Mabie Professor in the Neurosciences at The University of Chicago and CSO of Seurat
"If continued testing demonstrates that nasal delivery of IGF-1 is safe and effective for treatment of migraine headaches in humans, Seurat has the potential of helping approximately 39 million migraine sufferers in the United States," said Martin Sanders, MD, Chairman of Seurat.
The studies were supported with funding from Seurat, the National Institute of Neurologic Diseases and Stroke, the University of Chicago's Institute for Translational Medicine, Polsky Center's George Schultz Innovation Fund, Booth School of Business's Edward L. Kaplan, '71, New Venture Challenge, the Chicago Biomedical Consortium, and CuresWithinReach. Source:
