Shareholder Information

Investor Overview

NovaBay is focused on developing innovative product candidates targeting the treatment or prevention of a wide range of infections in hospital and community environments. Many of these infections have become increasingly difficult to treat because of the rapid increase in infectious microbes that have become resistant to current drugs. Our in vitro and in vivo tests have demonstrated that our compounds kill a wide range of bacteria, viruses and other infection causing microbes, including those that are resistant to multiple antibiotics. We are developing hospital indications ourselves and have partnered certain other indications with Alcon, the world's leading eye care company, and with Galderma S.A., a world leader in dermatology.
