Omniox is an IND stage biotechnology company founded based on H-NOX technology developed in Michael Marletta’s laboratory at the University of California, Berkeley. We are developing the breakthrough H-NOX platform technology into first-in-class and best-in-class OMX oxygen delivery vehicles that treat a range of significant unmet medical needs where tissue hypoxia drives disease pathology and worsens patient outcomes. Our in-house team is composed of experienced scientific and biotechnology professionals, and our advisory boards include world-leading experts in the appropriate fields of medicine, science, and business. Omniox has received grants and other funding from the National Cancer Institute, National Institute of Neurological Disorders and Stroke, the Wellcome Trust, and private investors. Omniox adheres to NIH/PHS Financial Conflict of Interest requirements.

Jonathan Winger, PhD

Co-Founder and CEO

Jonathan Winger is co-inventor of the H-NOX technology from which OMX therapeutics are derived, and has 20+ years of experience with production and study of H-NOX and other proteins. Prior to assuming the role of CEO, he oversaw the design and characterization of candidate OMX therapeutics, directed process and analytical development, and managed the manufacture of clinical material. Prior to Omniox, Jonathan was an American Heart Association Postdoctoral Fellow at the University of California, Berkeley, where he carried out biochemistry and structural biology studies on H-NOX proteins, kinases, and other proteins. He obtained his PhD in Medicinal Chemistry at the University of Michigan, where he used spectroscopy and enzymology to study the role of soluble guanylate cyclase (sGC), an H-NOX-containing protein, in nitric oxide signaling pathways. Insights gained from this work contributed to the conception and founding of Omniox. Jonathan has published numerous research papers and abstracts, co-authored several book chapters, is a PI on several research grants, and is an inventor on multiple patents.
