Propanc Biopharma Reports Significant Effects of PRP Against the Tumor Microenvironment

Rhea-AI Summary

Propanc Biopharma (OTC Pink: PPCB) reported on the positive effects of its lead product candidate, PRP, against tumor microenvironments, as highlighted by researcher Belén Toledo Cutillas at the University of Jaén. PRP demonstrated an ability to inhibit tumor development, reduce cell proliferation, and promote healthy cell characteristics. This research emphasizes PRP's potential in combating drug resistance and metastasis, which are significant challenges in cancer treatment. PRP consists of trypsinogen and chymotrypsinogen, and acts selectively on tumor cells, targeting various cancers.

Positive

• PRP shows anti-tumor effects, inhibiting tumor development.
• Reduces cell proliferation and promotes differentiation.
• Potential to address drug resistance and prevent metastasis.

Negative

• None.

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 significant effects of PRP against the tumor microenvironment and pre-metastatic niche has been reported by the Company’s joint researcher, Mrs. Belén Toledo Cutillas MSc, at the laboratory of Professor Macarena Perán, PhD, University of Jaén. Treatment with PRP was shown to have a favorable impact inhibiting, slowing, or reversing tumor development by acting as an anti-tumor agent, decreasing tumor cell proliferation, developing a non-malignant phenotype (observable characteristics) and promoting cell adhesion (sticking close to one another) and differentiation (cell specialization rather than stem cell like). It was concluded that PRP could have a significant impact on the tumor microenvironment as a potential clinical application. PRP is a combination of the two proenzymes trypsinogen and chymotrypsinogen.

Cancer remains one of the leading causes of death, globally. Despite recent advances in understanding its molecular and genetic basis, more than one third of those affected die each year from cancer. These alarming results are mainly attributed to current therapies not fully effective against cancer cells which may develop drug resistance, leading to recurrence and metastasis, causing more than 90% of cancer-related deaths. According to Mrs. Cutillas, “This is why we need to find better and more effective therapeutic strategies”. She explains that tumor formation is influenced by two factors, genetic changes in tumor cells and the rearrangement of components of the tumor microenvironment. In recent years, cancer research has focused on the tumor microenvironment.

Numerous assays, in vitro and in vivo studies, were conducted by Mrs. Cutillas confirming that PRP appears to have an anti-tumor effect and can act selectively against specific tumor elements, without affecting the non-tumor microenvironment and preventing its malignification (i.e., the process of making malignant).

Dr Julian Kenyon, MD, MB, ChB, Propanc’s Chief Scientific Officer said, “The work undertaken by Mrs Cutillas highlights the significant potential applications of PRP in a clinical setting, specifically relating to drug resistance, and consequently recurrence and metastasis, which is the biggest cause of death for sufferers. The pioneering research being undertaken with our joint researchers at the Universities of Jaén and Granada, continues to confirm our belief in the therapeutic potential of PRP, and may lead to exciting new ways to treat cancer patients suffering from solid tumors whilst reducing the threat of recurrence.”

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.

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. For more information, please visit www.propanc.com.

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.
