Result Consistent with Immunologic Cell Death Caused by PV-10

KNOXVILLE, Tenn.--(BUSINESS WIRE)--Provectus Biopharmaceuticals, Inc. (NYSE MKT: PVCT,, a clinical-stage oncology and dermatology biopharmaceutical company ("Provectus"), today announced data discussing the immunologic effects of PV-10 on colon cancer cells were presented yesterday at the 11th Annual Academic Surgical Congress in Jacksonville, Florida.

The abstract, titled "PV-10 Induces Potent Immunogenic Apoptosis in Colon Cancer Cells," was presented by N. M. Kunda of the University of Illinois at Chicago, Division of Surgical Oncology, Department of Surgery, College of Medicine, Chicago, IL, USA. The research team is led by Dr. A.V. Maker, and co-authors in addition to Drs. Kunda and Maker are: J. Qin, G. Qiao also of UIC, Division of Surgical Oncology, Department of Surgery. The team of authors also includes B. Prabhakarof the University of Illinois at Chicago, Department of Microbiology & Immunology, College of Medicine, Chicago, IL, USA. Dr. Maker belongs to both Departments.

In the presentation, Dr. Kunda noted that in vitro testing of PV-10 on colon cancer (murine CT-26 cells) showed cytotoxicity consistent with immunogenic apoptosis. Further, he stated that the researchers observed cell arrest, apoptosis, autophagy and endoplasmic reticulum (ER) stress. He concluded that these results are consistent with immunologic cell death caused by PV-10.

Dr. Eric Wachter, CTO of Provectus, said, "The work reported in Dr. Kunda's presentation further expands our understanding of the mechanism of action of PV-10 as an ablative immunotherapy for solid tumors, and parallels immunologic signaling noted upon ablation of melanoma with PV-10."

About the Academic Surgical Congress

The Academic Surgical Congress is organized by the Association for Academic Surgery (AAS) and the Society of University Surgeons (SUS). The purpose of the AAS is to stimulate young surgeons and surgical scientists to pursue careers in academic surgery and support them in establishing themselves as investigators and educators; to provide a forum for senior surgical residents, fellows and junior faculty members to present papers on subjects of clinical, laboratory or educational research; and to facilitate the development of young surgeons and surgical scientists as investigators and educators. Its additional mission is to inspire and develop young academic surgeons. The SUS exists to advance the art and science of surgery by (1) the encouragement of its members to pursue original investigations both in the clinic and in the laboratory; (2) the development of methods of graduate teaching of surgery with particular reference to the resident system; (3) free and informal interchange of ideas pertaining to the above subjects.

Risks and uncertainties that could cause our actual results to materially differ from those described in forward-looking statements include those discussed in our filings with the Securities and Exchange Commission (including those described in Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2014) and the following:

  • our determination, based on guidance from the FDA, whether to proceed with or without a partner with the fully enrolled phase 3 trial of PV-10 to treat locally advanced cutaneous melanoma and the costs associated with such a trial if it is necessary to complete (versus interim data alone);
  • our determination whether to license PV-10, our investigational drug product for melanoma and other solid tumors such as cancers of the liver, if such licensure is appropriate considering the timing and structure of such a license, or to commercialize PV-10 on our own to treat melanoma and other solid tumors such as cancers of the liver;
  • our ability to license PH-10, our investigational drug product for dermatology, PH-10, on the basis of our phase 2 atopic dermatitis and psoriasis results, which are in the process of being further developed in conjunction with mechanism of action studies; and
  • our ability to raise additional capital if we determine to commercialize PV-10 and/or PH-10 on our own, although our expectation is to be acquired by a prospective pharmaceutical or biotech concern prior to commercialization.
