PV-10's Systemic Tumor-Specific Immune Response is Subject of Research Article Published in PLOS ONE

KNOXVILLE, Tenn.--(BUSINESS WIRE)-- Provectus Pharmaceuticals, Inc. (OTCQB: PVCT, http://www.pvct.com), a development-stage oncology and dermatology biopharmaceutical company, announces that an article based on research conducted at the Moffitt Cancer Center with intralesional PV-10 has been published in PLOS ONE, an international, peer-reviewed, open-access, online publication. The article, entitled, "Intralesional Injection of Rose Bengal Induces a Systemic Tumor-Specific Immune Response in Murine Models of Melanoma and Breast Cancer," was authored by Paul Toomey, M.D., Krithika Kodumudi, Ph.D., Amy Weber, Lisa Kuhn, Ellen Moore, Arnod A. Sarnaik, M.D. and Shari Pilon-Thomas, Ph.D., all researchers with Moffitt's Immunology Program. The featured work resulted in part from a Provectus-sponsored research program led by Pilon-Thomas.

Provectus's PV-10, a 10% solution of Rose Bengal, is currently being examined as a novel cancer therapeutic. It is designed to selectively target and destroy cancer cells without harming surrounding healthy tissue, significantly reducing potential for systemic side effects. In melanoma patients, intralesional (IL) injection of PV-10 has led to regression of injected lesions as well as uninjected distant metastases (i.e., bystander lesions).

The PLOS ONE article, based on results of a Moffitt study initially presented in April 2013 at the annual meeting of the American Association of Cancer Research, examines the immunologic mechanism of PV-10 treatment in murine models of breast cancer and melanoma, to determine how IL PV-10 therapy induces the systemic anti-tumor immune response apparent in bystander responses in clinical trial participants.

The researchers conclude that intralesional PV-10, in addition to reducing the growth of directly injected tumors, leads to the induction of a robust anti-tumor T cell response and supports the use of PV-10 to induce systemic anti-tumor immunity in the treatment of metastatic melanoma and breast cancer. In addition to demonstrating that intralesional PV-10 therapy induces tumor-specific T cell-mediated immunity in multiple histologic subtypes, the article's authors note that their research supports the concept of combining IL PV-10 with immunotherapy for advanced malignancies.

Dr. Craig Dees, PhD, CEO of Provectus Pharmaceuticals, commented, "We are delighted to see that this valuable research conducted at the Moffitt Cancer Center, designed to elucidate the immunologic mechanism of action of intralesional Rose Bengal, has been published by an internationally recognized peer-reviewed journal. As the on-going companion clinical study continues, we are learning more about PV-10's unique mechanisms of action and its potential to induce a systemic immune response both as a monotherapy and potentially as a synergistic adjunct to other cancer therapeutics."

About Provectus Pharmaceuticals, Inc.

Provectus Pharmaceuticals specializes in developing oncology and dermatology therapies. Its novel oncology drug PV-10 is designed to selectively target and destroy cancer cells without harming surrounding healthy tissue, significantly reducing potential for systemic side effects. Its oncology focus is on melanoma, breast cancer and cancers of the liver. The Company has received orphan drug designations from the FDA for its melanoma and hepatocellular carcinoma indications. Its dermatological drug PH-10 also targets abnormal or diseased cells, with the current focus on psoriasis and atopic dermatitis. Provectus has recently completed Phase 2 trials of PV-10 as a therapy for metastatic melanoma, and of PH-10 as a topical treatment for atopic dermatitis and psoriasis. Information about these and the Company's other clinical trials can be found at the NIH registry, www.clinicaltrials.gov.
