NVC-422, or AL-46383A, is a stable compound based on the chemical structures of N-chlorotaurine (NCT) and N,N-dichlorotaurine, which are naturally occurring antimicrobial agents produced by the body’s white blood cells to fight invasive pathogens.

Alcon is conducting a Phase 2 clinical trial of this compound for the treatment of viral conjunctivitis, a form of “pink eye”. The randomized, placebo-controlled trial is enrolling approximately 250 patients at more than 30 medical centers in the United States and worldwide. It is designed to determine the safety and efficacy of NVC-422 or AL-46383A.

About NovaBay’s Aganocide® Compounds

The Aganocide® compounds are novel, proprietary, synthetic N-chlorinated antimicrobial molecules specifically developed by NovaBay to mimic the body’s natural defense against infection. The Aganocide compounds maintain biological activities while improving the stability of naturally occurring N-chlorinated antimicrobial molecules. These highly differentiated, first-in-class, small molecule, patented new chemical entities may deliver the same or better efficacy than currently used antibiotics without contributing to the growing rise of antibiotic-resistant bacterial strains. In preclinical testing, the Aganocide compounds have been shown to be highly effective against bacteria, including its multi-drug resistant strains (such as MRSA), viruses and fungi. They also have been demonstrated to be effective against bacteria in biofilm, which render most antibiotics ineffective. The Aganocide compounds have a broad therapeutic index while providing a high degree of potency and tolerability as well as dosing versatility and flexibility.

About NovaBay Pharmaceuticals, Inc.

NovaBay Pharmaceuticals is a clinical stage biotechnology company focused on developing its proprietary and patented Aganocide® compounds, which are novel, synthetic anti-infective product candidates with equivalent activity to the active antimicrobial molecules generated within white blood cells. NovaBay’s Aganocide compounds are being developed to treat and prevent a wide range of infections without causing bacterial resistance. NovaBay has internal development programs aimed at addressing hospital and respiratory infections. The company has a license and research collaboration agreement with Alcon for use of its Aganocide compounds to treat eye, ear and sinus infections as well as for contact lens care. NovaBay has also entered into an agreement with Galderma S.A. to develop and commercialize Aganocide compounds in acne, impetigo and other dermatological indications.
