- 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. Dr. Parel and the OBC team have spent more than ten years advancing RB PDAT technology against different types of infectious keratitis.
ARVO 2024 RB PDAT presentations included:
- Evaluating the Safety of Rose Bengal Photodynamic Therapy, Huang et al., BPEI (Poster no. B0448, Session: Cornea),
- Rose Bengal Photodynamic Antimicrobial Therapy as an Adjuvant Treatment for Infectious Keratitis, Eskenazi-Betech et al., Instituto de Oftalmologia Fundacion Conde de Valenciana IAP (Mexico) (B0338, Cornea),
- Assessment of photosensitizer concentration with a Singlet Oxygen luminescence dosimeter for Photodynamic Antimicrobial Therapy, Carrera et al., BPEI (B0570, Cornea),
- Clinical outcome in patients with infectious keratitis treated with Rose Bengal Photodynamic Antimicrobial Therapy (RB-PDAT) at the Federal University of Sao Paulo (UNIFESP), Tabuse et al., Universidade Federal de São Paulo (Brazil) (B0575, Cornea),
- Enhanced Fungal Inhibition with High-Dose Rose Bengal Photodynamic Antimiocrobial Therapy, Merikansky et al., BPEI (B0580, Cornea),

- Preclinical/Poster: Exploring the Combination of Rose Bengal Photodynamic Antimicrobial Therapy and Existing Antifungals, Krishna et al., BPEI (B0010, Immunology/Microbiology).
RB PDAT is the subject of two international Phase 3 randomized controlled trials for acanthamoeba and fungal (NCT05110001) and bacterial (NCT06271772) keratitis, and has been used to treat infectious keratitis patients in four countries to date:
- U.S.: BPEI (first clinical reporting: Naranjo et al. 2019),
- India: LV Prasad Eye Institute (Bagga et al. 2022) and Aravind Eye Care System (NCT05110001 data readout planned in Q4 2024),
- Brazil: Universidade Federal de São Paulo (ARVO 2024), and
- Mexico: Instituto de Oftalmología FAP (ARVO 2024).
