KNOXVILLE, Tenn.--(BUSINESS WIRE)--Provectus Biopharmaceuticals, Inc. (NYSE MKT: PVCT, www.pvct.com), a clinical-stage oncology and dermatology biopharmaceutical company ("Provectus"), today reported that the Journal of Clinical and Cellular Immunology has published a paper titled, "The Potential of Intralesional Rose Bengal to Stimulate T-Cell Mediated Anti-Tumor Responses." The paper can be found online at http://www.omicsonline.org/open-access/the-potential-of-intralesional-rose-bengal-to-stimulate-tcell-mediated-antitumor-responses-2155-9899-1000343.php?aid=59072
Authors Ajay V Maker, Bellur Prabhakar, and Krunal Pardiwala state that their "article serves to evaluate the potential of intralesional rose bengal [RB] to stimulate T-cell mediated anti-tumor responses in in-vitro, pre-clinical, and clinical studies." The review covers findings in both animal models and human clinical trials covering the use of intralesional RB in the treatment of: melanoma, breast cancer, ovarian cancer, gastric cancer and sarcoma.
They conclude, "Our current research is establishing the role of RB in generating anti-tumor immune responses in gastrointestinal cancer and liver metastases. Decrease in tumor burden and stimulation of an immune response with PV-10 has been demonstrated in animal models of metastasis, and correlations of these responses in clinical studies is consistent with such results. That PV-10 treatment can potentially increase circulating cytotoxic T-cells, even in patients who were previously treated with immune-activating checkpoint blockade, supports the possibility that RB induced cytotoxicity may activate T-cells that are responsible for the bystander effect on untreated lesions. As such, intralesional therapy with RB may be a promising new mode of therapy to stimulate T-cell mediated anti-tumor immune responses."
