The Canadian foundation patent is the final application in the Company’s foundation patent family to achieve allowance. This means that allowance or grant status has been secured in every jurisdiction in which the Company filed a foundation patent application. Propanc has an accepted application or achieved grant status for the foundation patent in over 30 different countries across North America, Europe, Asia, the Middle East and Japan.
For the US granted CSCs patent, the claims cover a method to minimize the progression of cancer in a patient who has already received a first line treatment by detecting the presence of CSCs followed by administering PRP. This patent describes the clinical application of PRP when the patient experiences a relapse and the cancer returns after primary standard of care has been applied.
"The milestones achieved for our intellectual property portfolio in North America are highly significant, as we now have patents in force in every jurisdiction selected by the Company for future commercialization of PRP," said James Nathanielsz, BAS, MEI, Propanc’s Chief Executive Officer. "This represents perseverance and 15 years of hard work to reach a stage where we have established our IP portfolio. Our technology is a novel approach for the treatment and prevention of metastatic cancer from solid tumors, which is the leading cause of death for sufferers. Our therapy is free from side effects normally associated with standard treatment approaches, based off our limited clinical experience from treatment. We look forward to advancing PRP to a First-In-Human study in advanced cancer patients to further establish the benefits of this first-in-class treatment."
Dr Julian Kenyon, MD, MB, ChB, Propanc’s Chief Scientific Officer, said, "More than 15 years ago, we determined to find a way to patent this unique treatment approach for cancer sufferers based on an initial investigation at my clinical practice. I believe PRP can become an important treatment approach to control the spread of solid tumors by targeting CSCs. We are very interested in possible clinical applications of PRP, such as treating resistant tumors post standard therapy, or as a chemo-sensitizing agent. We expect to continue to grow and expand our intellectual property portfolio whilst advancing PRP into the clinic to establish proof of concept in a target patient population, and identify a suitable partner for licensing."
PRP is a mixture of two proenzymes, trypsinogen and chymotrypsinogen from bovine pancreas, administered by intravenous injection. A synergistic ratio of 1:6 inhibits growth of most tumor cells. Examples include kidney, ovarian, breast, brain, prostate, colorectal, lung, liver, uterine, and skin cancers.
