Founding Story

Gateway stems from a collaboration between doctors at Washington University in St. Louis (WUSTL). After screening FDA-approved drugs in 2006 and discovering a family of drugs that can be used against hearing loss, Drs. Bao, Chole, and Perez formed Gateway Biotechnology, Inc. in 2011 to help transition their preclinical findings into medical interventions against hearing loss.

​Gateway focuses on drug repurposing for hearing disorders by identifying promising drug combinations or drugs not yet available in the United States. By working with academic institutions and pharmaceutical companies, we have developed functional technology platforms to validate the safety, efficacy, and quality of our product lines.

Playing chess. Gateway Biotechnology.
