Rose Bengal disodium

Collaboration between Bascom Palmer Eye Institute and Provectus Biopharmaceuticals KNOXVILLE, TN / ACCESSWIRE / December 10, 2024 / VisiRose, a clinical-stage biotechnology company, is introducing Rose Bengal Photodynamic Antimicrobial Therapy (RB PDAT), a groundbreaking, non-invasive investigational treatment for infectious keratitis and other serious eye infections developed by the University of Miami Miller School of Medicine's Bascom Palmer Eye Institute (BPEI). VisiRose, a newly launched company of Provectus Biopharmaceuticals (OTCQB:PVCT) and the University, is focused on commercializing this innovative ocular research by combining a formulation of Provectus's pharmaceutical-grade bioactive synthetic small molecule Rose Bengal Sodium (RBS) and BPEI's light-based medical device to treat eye infections caused by bacteria, fungi, and parasites.RB PDAT offers a potential solution to the growing global problem of antimicrobial resistance (AMR), providing a broad-spectrum ocular therapy that may be safe, effective, and cost-efficient. The treatment has shown rapid infection resolution and improved patient outcomes in clinical trials across the U.S., India, Brazil, and Mexico."RB PDAT is a revolutionary, non-invasive treatment showing remarkable promise for patients with severe infectious keratitis. This innovative therapy harnesses the power of light to combat infection and offers new hope for preserving vision," said Jean-Marie Parel, IngETS-G, Ph.D., FAIMBE, FARVO, Director and co-founder of the Ophthalmic Biophysics Center at BPEI.Guillermo Amescua, M.D., Professor of Clinical Ophthalmology, Medical Director of the Ocular Microbiology Laboratory, and a board-certified ophthalmologist at BPEI added, "VisiRose is crucial for translating the innovation of RB PDAT from the laboratory to a widely accessible treatment, ultimately benefiting countless patients worldwide.""VisiRose is the bridge that connects innovation with impact. It enables us to bring the hope of RB PDAT to patients who desperately need it, transforming lives and shaping the future of eye care," said Ed Pershing, Chairman of the Board of Directors of VisiRose and Provectus.Dominic Rodrigues, Acting CEO of VisiRose added, "RB PDAT offers a beacon of hope for patients facing the threat of vision loss from infectious keratitis. This innovative therapy, with its targeted action and dual benefits, represents a significant advancement in eye care, paving the way for a brighter future for those struggling with this challenging condition."In more than 500 patients, RB PDAT has shown promising results in treating severe eye infections where traditional therapies have failed. VisiRose is poised to address a significant gap in the $60 billion global ophthalmic market, focusing on regions and populations impacted by rising AMR and the lack of access to effective treatments.About VisiRoseVisiRose is a newly launched, clinical-stage biotechnology company of the University of Miami and Provectus Biopharmaceuticals, focused on commercializing the Miller School of Medicine's Bascom Palmer Eye Institute and its Ophthalmic Biophysics Center's innovative ocular research using Provectus's bioactive synthetic small molecule Rose Bengal Sodium (RBS).

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.
