Plans To Commence World-First Phase 1b First-In-Human (FIH) Study of PRP Q1, 2027

MELBOURNE, Australia, Sept. 29, 2026 (GLOBE NEWSWIRE) -- Propanc Biopharma, Inc. (Nasdaq: PPCB) (“Propanc” or the “Company”), a biopharmaceutical company focused on developing novel treatments for chronic diseases, including recurrent and metastatic cancer, today announced an update on corporate progress and reported year-end financial results as of June 30, 2026 (Year end June 30).

CORPORATE HIGHLIGHTS

To commence a world-first Phase 1b FIH study of PRP in Q1, 2027

The multicenter, open-label study will enroll up to 50 patients with advanced solid tumors, including pancreatic, ovarian, and refractory prostate cancers, at trial centers across Australia. The two-part design, dose escalation (Part A) followed by dose expansion (Part B), is intended to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and preliminary antitumor activity of PRP.

Several workstreams are advancing in parallel to support study start:

  • Manufacturing: GMP manufacture of finished drug product is underway. A small-scale technology transfer run has been completed. Two scale-up runs are scheduled this month, with an engineering run planned for late October. Raw drug substance supply for the PRP formulation is secured after recent audit and vendor qualification processes were successfully completed.
  • Bio-analytics: PK method validation has commenced. Development of an anti-drug antibody assay is underway, and in-use stability testing of the finished PRP formulation is scheduled.
  • Regulatory and ethics: Supporting documentation for Human Research Ethics Committee (HREC) submission is in preparation, including the Investigator’s Brochure (IB), a briefing document drawn from the IB, and the clinical trial protocol. Documents will be provided to investigators at Australian trial sites for feasibility assessment ahead of the planned HREC submission in November 2026.

PRP will be administered as a weekly intravenous infusion on Days 1, 8, 15, and 22 of each 28-day cycle. Treatment may continue until a withdrawal criterion is met.

Compelling new preclinical and early translational data for its lead candidate PRP in pancreatic ductal adenocarcinoma (PDAC)

In orthotopic and patient-derived xenograft (PDX) models of advanced PDAC, three-times-weekly intravenous PRP achieved:

  • Greater than 90%, mean, tumor growth inhibition versus vehicle controls (p < 0.001).
  • Marked reduction in metastatic burden in the liver and peritoneum.
  • Significant remodeling of the tumor microenvironment, including decreased cancer-associated fibroblast activity, reduced fibrosis, and suppression of epithelial-mesenchymal transition (EMT) markers.
  • Enhanced sensitivity of chemo-resistant PDAC cells to standard-of-care gemcitabine/nab-paclitaxel, supporting lower chemotherapy doses with improved efficacy.
  • Median overall survival extension of more than 2.5-fold in treated animals compared with controls.

Results were built on previously reported >85% tumor growth inhibition data and peer-reviewed findings on PRP’s effects on PDAC fibroblasts. Limited prior compassionate-use experience with related proenzyme formulations has shown signals of prolonged survival in advanced solid-tumor patients with a favorable safety profile and no severe treatment-related adverse events.

Memorandum of Understanding (MOU) with Avance Clinical Pty Ltd

The MOU sets out the shared intent of Propanc and Avance to work together to support the clinical delivery of Propanc’s Phase 1b, FIH clinical study for PRP. Importantly, both parties intend to approach the collaboration in a spirit of openness, scientific rigor, and shared problem-solving with the goal of advancing PRP efficiently from FIH into Proof-of-Concept and, as data supports, later-phase development. Avance Clinical is a full-service Contract Research Organization (CRO) headquartered in Australia, with extensive operations across North America, Asia Pacific, New Zealand and Europe. With more than 30 years of experience leading early phase clinical trials, they leverage the unique advantages of the Australian market, including rapid ethics approval, and up to 43.5% off with the Australian R&D tax rebate, to provide biotech companies with an accelerated pathway to clinical success.

Contract and Development Manufacturing Organization (CDMO) for GMP manufacture of PRP

The Spanish based CDMO provides end-to-end services for preclinical and clinical projects, with extensive experience in biologics production (plasmid DNA and recombinant proteins) providing services of cell line generation, banking and characterization, analytical development, process development and batches production of both drug substances and drug products. Management are pleased to undertake this pivotal step for GMP production of PRP for the upcoming Phase 1 FIH clinical study.

Service Agreement with FyoniBio GmbH to Establish & Validate Pharmacokinetics Assay for Phase 1b FIH Study

Management has executed a service agreement with FyoniBio GmbH (formerly Glycotope, est. 2010), a German Contract Development Organization (CDO) based in Berlin for establishing and validating a liquid chromatography-mass spectrometry (LC-MS) based pharmacokinetics (PK) assay. The objective is to quantify the Company’s lead asset, PRP, consisting of two proenzymes trypsinogen and chymotrypsinogen, as well as their activated enzyme forms trypsin and chymotrypsin from human serum during the Phase 1b FIH study.

Multi-Yr, Anti-Aging & Cancer Research Collaboration with the Universities of Jaén & Granada, Spain

A multi-year Joint Research Collaboration Agreement has been established with the Universities of Jaén (UJA) and Granada (UGR), Spain. The collaboration involves the evaluation of a senescence-modulating (i.e., anti-aging) compound to mitigate senescence and to complete experiments to further support the claims of recently filed fibrosis and cancer related patent applications, requested by Propanc to UJA’s research group “Biological Technologies of The University of Jaén” and UGR’s Research Group, “Advanced Therapies: Differentiation, Regeneration and Cancer.”

Management Commentary

“The Propanc Executive team are delighted with advancements made in the past financial year,” said Mr. James Nathanielsz, Propanc’s Chief Executive Officer. “The Company is poised to capitalize on the foundation set in the next financial year with the advancement of PRP to a Phase 1b FIH study in up to 50 advanced cancer patients with solid tumors such as pancreatic, ovarian and refractory prostate cancers. Recent clinical advancements observed by companies such as Revolution Medicines and Erasca through KRAS inhibitors for pancreatic cancer are groundbreaking and tremendously exciting, but there is more work to be done to eliminate recurrence and metastasis in patients suffering from this killer disease. PRP is a potential breakthrough therapy that modulates the tumor micro-environment by targeting the EMT (epithelial-mesenchymal transition) process, which drives metastasis, invasion and recurrence from CSCs (cancer stem cells) which often lie dormant, post treatment, causing the cancer to return and spread. By eliminating this threat, not only can PRP improve survival, but is also non-toxic to healthy cells, meaning that patients could have a better quality of life, as well as enhance more durable response rates in combination with other treatments such as chemotherapy, checkpoint inhibitors, or KRAS inhibitors. We look forward to executing our scientific and clinical research activities in the 2026-2027 financial year.”
