MELBOURNE, Australia, June 16, 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 that Mr. James Nathanielsz, Propanc's Chief Executive Officer, toured the GMP (Good Manufacturing Practice) facility of the European CDMO (Contract Development and Manufacturing Organization) in preparation for the upcoming production of the Company's lead asset, PRP, for the upcoming Phase 1b, First-In-Human (FIH) study in 30 – 40 advanced cancer patients suffering from solid tumors. In addition to touring the facility, the joint development team, consisting of Propanc's R&D team and the key personnel from the CDMO engaged in discussions regarding the proposed project timelines, including the pre-production, engineering run and future GMP production and release of PRP, a world-first, fixed combination of two proenzymes, trypsinogen and chymotrypsinogen administered by I.V. injection once weekly. The plan is to undertake the following steps towards preparation of the finished drug product for the Phase 1b, FIH study, according to the following target dates:

Preproduction in August 2026
Engineering run in October 2026
GMP manufacture to commence December 2026

It is anticipated that four weeks stability data post the engineering run will be sufficient to support a Phase 1B clinical trial application in Australia planned for submission in 2026.

Established in 2017, they provide services to a wide range of clients, including startups, large pharmaceutical companies, and other CDMOs, helping their biologic products reach the market efficiently. Operating across two building sites totaling 4,500sqm, with additional space reserved for future expansion, key facility allocations include 500sqm for development activities, 1,400sqm for cGMP manufacturing, 400sqm for analytical testing and a 400sqm cGMP warehouse. The company holds multiple certifications, including ISO 9001:2015, ISO 13485:2016, ISO 14001:2015, and GMP compliance, ensuring high-quality standards across all stages of biologics production.

"Visiting our CDMO partner provides tremendous benefits being able to visualize future cGMP production of PRP, building the foundation for a strong partnership and creating an understanding between the parties about the vision for the future, in particular, our plans for PRP as a world first cancer therapy for the treatment and prevention of metastatic cancer from solid tumors, which are often incurable," said Mr. Nathanielsz. "In addition, visiting the facility in person has helped me to appreciate the significant capital investment into their modern equipment and building facilities which are perfectly suited for early-stage developers whom they desire to grow with. I am looking forward to working with our partner of choice after an extensive process to identify the right characteristics in the people, their facilities, and processes. We believe we have the tools in place to advance PRP through clinical development as efficiently as possible."
