Chymotrypsinogen/trypsinogen

MELBOURNE, Australia--(BUSINESS WIRE)-- Propanc Biopharma, Inc. (OTC Pink: PPCB) (“Propanc” or the “Company”), a biopharmaceutical company developing novel cancer treatments for patients suffering from recurring and metastatic cancer, today announced that PRP enhances the sensitivity of resistant pancreatic tumor cells to standard chemotherapy treatment and alters the tumor microenvironment by decreasing the fibrotic tissue and its malignancy (ability to spread into surrounding tissues). The results were reported by the Company’s joint researcher, Mrs. Belén Toledo Cutillas, MSc, at the laboratory of Professor Macarena Perán, PhD, University of Jaén, Granada, Spain. Various methods, including apoptosis (programmed cell death) and viability analysis, live/dead assays, and RT-qPCR (real time quantification of gene expression) analyses confirmed PRP enhances the sensitivity of pancreatic tumor cells to standard chemotherapy treatment and decreases expression of genes related to chemoresistance. It was also proven that a major pathway, TGF-β, responsible for tumorigenesis (production or formation of tumors) and metastasis (cancer spread), is involved with the observed effects by inhibiting this pathway after PRP treatment. Similar analyses and an in vivo (in a living organism) study evaluating the effects on the tumor microenvironment confirmed transformational changes to the extracellular matrix components of the resistant tumors and according to Mrs. Cutillas, “seems to re-educate the malignant tumor cells by inducing apoptosis and reversing their malignant phenotype (cellular characteristics).” Dr Julian Kenyon, MD, MB, ChB, Propanc’s Chief Scientific Officer said, “Results from the experiments conducted by Belen demonstrates the effects of PRP on reducing chemoresistance in pancreatic tumor cells, which is a significant issue among pancreatic adenocarcinoma (PDAC) patients, who have a poor 5-year survival rate of less than eight percent. We look forward to investigating the clinical effects in patients as we progress with future planned clinical trials, where an opportunity for a combinatorial therapeutic strategy may be uncovered to treat these resistant tumors.” 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. About Propanc Biopharma, Inc. Propanc Biopharma, Inc. (the “Company”) is developing a novel approach to prevent recurrence and metastasis of solid tumors by using pancreatic proenzymes that target and eradicate cancer stem cells in patients suffering from pancreatic, ovarian, and colorectal cancers.

The Company’s novel proenzyme therapy is based on the science that enzymes stimulate biological reactions in the body, especially enzymes secreted by the pancreas. These pancreatic enzymes could represent the body’s primary defense against cancer.

Initial Discussion Held with Clinical Investigator at Australia’s Biggest Cancer Hospital MELBOURNE, Australia--(BUSINESS WIRE)-- Propanc Biopharma, Inc. (OTC Pink: PPCB) (“Propanc” or the “Company”), a biopharmaceutical company developing novel cancer treatments for patients suffering from recurring and metastatic cancer, today announced that the Company will target the Peter Mac Cancer Center in Melbourne, Australia, as the site for the First-In-Human (FIH) study for PRP in patients with advanced solid tumors. Initial discussion held previously with the Clinical Investigator confirmed the remaining development activities to be conducted by the Company prior to filing the clinical trial application for the FIH study. This includes the finished drug product manufacture and validation of the bioanalytical method to analyze the pharmacokinetics (movement of drug within the body) of PRP during the study. The Peter Mac Cancer Center is a world leading cancer research, education and treatment center and Australia’s only public health service dedicated to caring for people affected by cancer. They have 3,900 employees, including more than 750 laboratory and clinical researchers, all focused on providing better treatments, better care and potential cures for cancer. They are well placed to support the Company’s goals for a world first clinical study of PRP, as a long term, proenzyme therapy for the treatment and prevention of metastatic cancer from solid tumors by targeting and eradicating cancer stem cells, free from side effects normally associated with standard treatment approaches. “We are pleased to have engaged in positive initial discussion with Professor Mark Rosenthal, Director and FIH Clinical Study Investigator at the Peter Mac Cancer Center,” said James Nathanielsz, BAS, MEI, Propanc’s Chief Executive Officer. “We are excited about the opportunity to work with a world class facility like Peter Mac, and it was great to see our mutual excitement about a potential world first study for PRP as a new therapeutic approach to treat and prevent metastatic cancer from solid tumors. Our plan is to undertake the FIH study in Australia, given the favorable R&D cashback benefit where we will receive 43% of our R&D expenditure on local activities, as well as approval from the Australian Government for reimbursement some overseas activities as well. We will then plan to undertake subsequent clinical studies in Europe, as the preeminent region behind the USA, where we will undertake a Pre-IND meeting with the US Food and Drug Administration once we have clinical data from our FIH study. Achieving this exciting development stage in the not-too-distant future could prove transformative for the Company, and its shareholders.” Propanc is set to capitalize on favorable government incentives from the Australian government for future product and clinical development of PRP, receiving a 43.5% cash back benefit on all local R&D activities conducted in Australia. Furthermore, a Certificate for Advance Overseas Finding was received from the Board of Innovation and Science Australia to receive up to a 43.5% “cash back” benefit from overseas R&D expenses. Overseas activities to be undertaken include validation of the pharmacokinetics method for PRP and its manufacture of the finished product for the FIH study.
