Provectus Pharmaceuticals Receives US Patent Allowance to Provide Further Protection for Novel Photodynamic Drug PH-12KNOXVILLE, Tenn.--(BUSINESS WIRE)--Mar 4, 2008 - Provectus Pharmaceuticals, Inc. (OTC BB: PVCT), a development-stage oncology and dermatology biopharmaceutical company, has received allowance of a second US patent application protecting a novel photoactive analog of its lead photodynamic product PH-10, from the United States Patent and Trademark Office (USPTO). The pending patent covers systemic use of the drug, PH-12, for photodynamic treatment of cancer, skin diseases, and other tissue disorders using visible light activation.
"As with PH-10, visible light can be used to activate PH-12 in target tissue," noted Craig Dees, PhD, CEO of Provectus. "Because it was designed to have enhanced efficiency of activation, it is particularly suitable for treatment of internal body tissues or larger diseased areas."
Dees continued: "While we remain focused on clinical development of our lead therapeutic products, PV-10 for cancer and PH-10 for dermatology, this new patent will further solidify an important longer-term opportunity in our development pipeline. It is likely to be some time before we commence clinical testing of PH-12, but given the large potential value in markets worldwide, protection of this new technology enhances value for our shareholders now."
The allowance increases Provectus' US patent portfolio to five pending and seventeen issued patents, with the Company's most recent patent, US Patent 7,338,652, having issued earlier today. In mid-January, the Company received allowance of its patent application in India covering its lead dermatology agent, PH-10, along with a number of related agents, for treatment of skin diseases such as psoriasis and eczema. In February, Provectus received allowance of its patent applications in Europe and China covering diagnostic use of PV-10 and a number of related agents in CT and MRI imaging.
