Propanc Biopharma Receives Certificate of Grant for “Proenzyme Composition” Patent from US Patent & Trademark Office

Fourth US Granted Patent Captures Claims for Future Clinical Dose of PRP

MELBOURNE, Australia, Sept. 17, 2025 (GLOBE NEWSWIRE) -- Propanc Biopharma, Inc. (Nasdaq: PPCB) (“Propanc” or the “Company”), a biopharmaceutical company developing novel cancer treatments for patients suffering from recurring and metastatic cancer, today announced that a certificate of grant for the Company’s “proenzyme composition” patent was received from the US Patent & Trademark Office (USPTO). The patent specifically captures a future clinical dose of the Company’s lead asset, PRP. This is the fourth US patent granted in this key strategic jurisdiction. Currently, the Company’s intellectual property portfolio consists of 90 patents filed in major jurisdictions relating to the use of PRP against solid tumors.

The proenzymes composition patent is an important part of the IP portfolio covering a possible future clinical dose of PRP, as the Company advances to a Phase 1B, First-In-Human (FIH) study in advanced cancer patients suffering from solid tumors. The patent has also been granted in other major jurisdictions such as Europe, Japan and throughout Southeast Asia. PRP is targeting the global metastatic cancer treatment market, projected to be worth US$111.2 billion by 2027, according to Emergen Research.

“We continue to grow our intellectual property portfolio in the United States, which is our most important jurisdiction,” said Mr. James Nathanielsz, Propanc’s Chief Executive Officer. “Our lead asset, PRP, is an exciting method to prevent and treat metastatic cancer from solid tumors without the severe, or even serious side effects often associated with standard therapies. PRP is relatively non-toxic because it does not kill cancer cells directly but induces cell differentiation so that they become less malignant and die off naturally. This unique phenomenon is specific to PRP, which acts as an ‘EMT (epithelial to mesenechymal transition) modulator’, enforcing the cancer cells to behave more as a normalized cell so that it is no longer a threat. We are pushing towards the commencement of the Phase 1B study next year. We are also pursuing every avenue for raising sufficient capital and employing a digital asset diversification strategy to ensure optimal cash flow as we advance PRP towards important clinical milestones.”
