Rose Bengal disodium

Accelerates wound closure and improves wound healing KNOXVILLE, TN, May 21, 2024 (GLOBE NEWSWIRE) -- Provectus Biopharmaceuticals Inc. (“Provectus” or the “Company”) (OTCQB: PVCT) today announced that non-clinical data on Provectus’s proprietary, pharmaceutical-grade, rose bengal sodium (“RBS”) active pharmaceutical ingredient for the topical treatment of full-thickness cutaneous wounds were presented at the annual meeting of the Society for Investigative Dermatology (“SID”), held May 15-18, 2024 in Dallas, Texas. This work is part of research being conducted by Amina El Ayadi, PhD, Assistant Professor, Surgical Sciences Division of the Burn, Trauma, and Critical Care Research Laboratory in the Department of Surgery at the University of Texas Medical Branch at Galveston (“UTMB”). A copy of UTMB’s poster presentation is available here: . The UTMB team and Dr. El Ayadi concluded that: The application of multidose 0.01% RBS every other day under ambient light (“RBS treatment”) to full-thickness wounds showed: No toxicity or mortality, No loss in body weight, No organ abnormalities, and No observed adverse effect level at the highest tested dose, Transepidermal water loss was significantly reduced by 14 days, suggesting improvement in skin barrier function, Erythema was increased at seven days, suggesting increased blood flow and granulation tissue formation required for wound healing, Vascularity was increased between three and seven days, supporting pro-angiogenic activity needed for wound closure, RBS treatment: Accelerated wound closure (significant difference at three days), Increased collagen density at seven and 14 days, supporting increased wound remodeling and tissue regeneration, and Reduced angiogenesis after wound closure (day 14), which is beneficial in preventing fibrosis. About University of Texas Medical Branch at Galveston Starting from the Texas City Disaster of 1947, the deadliest industrial accident in U.S. history and one of history’s largest non-nuclear explosions, UTMB clinicians and researchers in the Department of Surgery have developed treatments that improve the survival chances of patients with massive burns, reduce scar formation, and accelerate patient recovery. Many novel treatments discovered by UTMB researchers have been adopted by specialist burn centers around the world. The Department of Surgery’s Burn, Trauma, and Critical Care Research Laboratory is equipped with an array of cutting-edge equipment and technologies that support its research activities, including a dedicated cell culture suite, confocal microscope, flow cytometer, Comprehensive Lab Animal Monitoring System, and bioprinter for 3D cell culture.

PDAT clinical outcomes for infectious keratitis from Brazil and Mexico 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.
