Provectus has announced new preclinical research published in The Journal of Antibiotics demonstrating that its pharmaceutical-grade rose bengal sodium (RBS) effectively inhibits the growth of colistin-resistant gram-negative (G-) bacteria and exhibits rapid-killing characteristics. Colistin is recognized as a last-resort treatment for severe bacterial infections and is classified by the WHO as critically important to human health. The research, led by Dr. Michio Kurosu at the University of Tennessee Health Science Center, shows that Provectus' RBS formulation (HP-RBf) has significant potential against these resistant pathogens. This reinforces the capability of RBS to contribute to combination therapies in treating infectious diseases, as stated by Dominic Rodrigues, Vice Chair of Provectus’ Board of Directors.
Provectus (OTCQB: PVCT) issued a letter to stockholders highlighting 2023 plans focused on maximizing long-term value. The company, a late-stage biotechnology firm, is advancing its lead molecule, rose bengal sodium (RBS), through multiple clinical trials targeting various cancers.

Provectus presented promising results from its ongoing Phase 1b/2 study of PV-10 and Keytruda for treating Stage III cutaneous melanoma at Melanoma Bridge 2022. Highlights include a 50% complete response rate (3/6 patients) and an 83% overall response rate (5/6 patients). Rapid complete responses were observed within 15 to 27 weeks. The study reported an 83% progression-free survival rate and a 100% overall survival rate for complete responders after 18 to 36 months. The findings suggest significant potential for the combination therapy, with plans for a Phase 2/3 trial in 2023.
