Gemstone Biotherapeutics was founded in Baltimore, MD in 2013 as a pre-clinical research and development initiative built on a foundation of exclusively-licensed IP from The Johns Hopkins University. We are currently focused on incubating and commercializing two specific wound healing products from our pipeline that target and repair the physiological deficiencies of acute and chronic wounds to heal them more rapidly and ensure they remain healed.


Our best-in-class research collaborators include clinical and commercial institutions, including NYU Winthrop University Hospital, The Johns Hopkins University, and UPenn School of Veterinary Medicine. We are moving our technology through FDA approval, clinical trials, reimbursement studies in support of future productizing, licensing, or other strategic partnerships.
