KNOXVILLE, Tenn.--(BUSINESS WIRE)--Provectus Pharmaceuticals, Inc. (OTC BB: PVCT, http://www.pvct.com), a development-stage oncology and dermatology biopharmaceutical company, announced that final top-line data from its Phase 2 clinical trial of PV-10 for metastatic melanoma were presented at the ESMO (European Society for Medical Oncology) 2012 Congress in Vienna, Austria on October 1, 2012. The data were presented in Poster Presentation III, Abstract #1137P, "Immuno-chemoablation of metastatic melanoma with intralesional rose bengal." The poster was presented by Dr. Sanjiv Agarwala, M.D., Principal Investigator for the Phase 2 trial of PV-10, and Chief of Medical Oncology and Hematology at St. Luke's Hospital and Health Network in Bethlehem, PA. The poster was authored by Dr. Agarwala along with co-authors J.F. Thompson, B.M. Smithers, M. Ross, B.J. Coventry, D.R. Minor, C.R. Scoggins and E. Wachter.
The data presented on response rate and progression free survival corroborated previously presented preliminary data on these topics. Key results include:
Dr. Eric Wachter, PhD, Chief Technical Officer of Provectus and Study Director for the clinical trial, noted that, "These final analyses confirm previously reported trends from preliminary data. The high response rates for target and bystander lesions in Stage III subjects are particularly striking and illustrate the potential for PV-10 to benefit these challenging cases."
Dr. Agarwala, commenting on the reported data, stated, "These results further confirm the robust response that can be achieved with PV-10. This is particularly clear in Stage III patients where it is possible to inject all or virtually all of the patient's melanoma lesions. Despite the strict limits on dosing schedule in the Phase 2 protocol, many of the patients achieved excellent disease control or even complete remission. I find it quite remarkable that this included a number of subjects who experienced favorable response in their untreated skin or visceral lesions."

In addition to these phase 2 data, the company also provided further guidance on final design for its proposed Phase 3 Randomized Controlled Trial ("RCT") of PV-10 for metastatic melanoma. The study design is predicated on testing response of PV-10 in subjects most likely to derive clinical benefit from treatment of their cutaneous and subcutaneous melanoma lesions, specifically Stage III patients comparable to those investigated in the Phase 2 study. The design is anticipated to qualify as a pivotal trial under Special Protocol Assessment ("SPA") with the U.S. FDA. An SPA from the FDA is an agreement that the Phase 3 study design endpoints, statistical analyses and operational components of the planned clinical trials are acceptable to support approval of the product. Design parameters presented at ESMO include:
The study duration is estimated to be approximately 30 months, with commencement expected in late 2012 or early 2013 following completion of review for SPA.
Dr. Wachter, commenting on the Phase 3 study design, noted, "This study is designed to demonstrate delay or avoidance of progression of melanoma from a locoregional disease to a life-threatening systemic stage. The proposed study population experienced excellent response to PV-10 in the Phase 2 study, and this bodes well for the planned Phase 3 study, where subjects will receive treatment on an even more aggressive schedule than that allowed in Phase 2. Since our last meeting with FDA in late 2011, we have carefully studied the outcome of different sub-populations of subjects in the Phase 2 study, reviewed the criteria to be used for unambiguous assessment of response, and fostered relationships with key parties that will provide support in execution of the Phase 3 study. We look forward to formal review of the resultant protocol and supportive programmatic elements with FDA under the SPA process."
Craig Dees, Ph.D, CEO of Provectus said, "The protocol design presented at ESMO reflects guidance we've received during discussions with the FDA and the Australian Therapeutic Goods Association ("TGA") about our proposed Phase 3 trial for metastatic melanoma. We have also completed detailed operational planning, something which the FDA now frequently expects as part of the SPA package and a critical step to assure that the study runs smoothly. The SPA is probably the most important milestone Provectus will have achieved in our efforts to gain approval for PV-10. We expect to keep shareholders updated on our progress as we continue to advance the development of PV-10."
The European Society for Medical Oncology (ESMO) is the leading European professional organization, committed to advancing the specialty of medical oncology and promoting a multidisciplinary approach to cancer treatment and care. Since its founding in 1975 as a non-profit organization, ESMO's mission has been to advance cancer care and cure. It achieves this through fostering and disseminating good science that leads to better medicine and determines best practice.
