The proenzymes composition patent is an important part of the IP portfolio as it covers possible future clinical dosage ranges for PRP as the Company advances into early-stage clinical development. Japan is considered an important pharmaceutical market, which is estimated to reach $46.36 Billion revenue in 2024, according to www.statista.com. The largest sector is oncology drugs, projected to have a market volume of $8.95 Billion in 2024, which overall, is experiencing a surge in demand for innovative drugs driven by an aging population and increasing prevalence of chronic (long term) diseases (www.statista.com).

The cancer treatment patent describes a method to target and eradicate cancer stem cells (CSCs) using PRP which minimizes the progression of cancer in a patient. Currently, progression, or spread of cancer, called metastatic cancer, is the main cause of patient death for sufferers. Malaysia is one of the largest countries in South East Asia. In 2024, the projected revenue in the pharmaceutical market in Southeast Asia is expected to reach $13.40 Billion. The largest market within this market is oncology drugs, which is projected to have a market volume of $2.40 Billion this year, according to www.evaluate.com.

"We are building an extensive and mature intellectual property portfolio around the use of proenzymes as a novel treatment for advanced solid tumors," said Mr. James Nathanielsz, Propanc’s Chief Executive Officer. "We plan to grow our intellectual property portfolio by filing additional provisional patent applications, as we progress PRP into the clinic. Intellectual property protection is a cornerstone of our drug development strategy, as we seek to protect the tremendous value in our promising lead product candidate, PRP. We look forward to executing our plans to advance PRP into a Phase 1b clinical study in advanced cancer patients, as a novel therapy for the treatment and prevention of metastatic cancer from solid tumors by targeting and eradicating CSCs, but without the side effects normally associated with standard treatment approaches."

About PRP:

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 pancreatic, ovarian, kidney, breast, brain, prostate, colorectal, lung, liver, uterine, and skin cancers. Orphan Drug Designation status of PRP has been granted from the US Food and Drug Administration (FDA) for treatment of pancreatic cancer.
