KNOXVILLE, TN, May 14, 2024 (GLOBE NEWSWIRE) -- Provectus Biopharmaceuticals, Inc. (“Provectus” or the “Company”) (OTCQB: PVCT) today announced that clinical and non-clinical data on rose bengal photodynamic antimicrobial therapy (“RB PDAT”) were presented at the annual meeting of the Association for Research in Vision and Ophthalmology (“ARVO”), held May 5-9, 2024 in Seattle, Washington. The ARVO annual meeting brings together approximately 10,000 vision researchers, clinicians, and scientists from around the world for scientific sessions, poster presentations, and invited speaker sessions.

Provectus entered into an exclusive worldwide license agreement with the University of Miami (the “University”) in April 2024 for its intellectual property related to RB PDAT for treating bacterial, fungal, and parasitic (acanthamoeba) eye infections. The Company and University plan to form a start-up biotechnology company (e.g., “Eyecare NewCo”), potentially in the third quarter of 2024, aimed at commercializing the University’s PDAT light source medical device in combination with a drug formulation of Provectus’s proprietary pharmaceutical-grade rose bengal active pharmaceutical ingredient (“RB API”). The Company would contribute the RB PDAT license to and have an exclusive RB API supply arrangement with Eyecare NewCo.

RB PDAT emerged under the leadership of Jean-Marie Parel, IngETS-G, Ph.D., FARVO, Director of Bascom Palmer Eye Institute’s (“BPEI’s”) Ophthalmic Biophysics Center at the University of Miami Miller School of Medicine. Dr. Parel and the OBC team have spent more than ten years advancing RB PDAT technology against different types of infectious keratitis.
