PharmaCyte Biotech Successfully Completes Three-Month Stability Study

LAGUNA HILLS, Calif.–(BUSINESS WIRE)–#3monthstabilitystudypassesalltests–PharmaCyte Biotech, Inc. (OTCQB: PMCB), a biotechnology company focused on developing cellular therapies for cancer and diabetes using its signature live-cell encapsulation technology, Cell-in-a-Box®, announced today that it has successfully completed the three-month product stability testing that is required by the U.S. Food and Drug Administration (FDA) for its CypCaps™ and CypCaps™ passed all of the FDA-required tests. This is the final product that will be used in the company’s planned clinical trial in locally advanced, inoperable pancreatic cancer.

PharmaCyte’s Chief Executive Officer, Kenneth L. Waggoner, said of the completed three-month stability study, “We are pleased to announce that our Cell-in-a-Box® encapsulated cell product CypCaps™ has passed all of the FDA-required tests for the first three-months of a 24-month stability study. This is part of an ongoing study to determine the shelf life of the CypCaps™ final product that the FDA requires for all medical products. The data will be included in our IND. All future longer-term shelf life analyses, such as the next one at six months post-production, will be reported to the FDA but is not required for PharmaCyte to submit an IND.”

As based in the ICH guidelines, regulatory agencies around the world, including the FDA, require a shelf-life determination for all medical products. Living products, like cell therapies such as CypCaps™, as well as live vaccines etc., are particularly sensitive and more prone to inactivation over time, so it is especially important to determine the shelf-life for these products.

A battery of tests was performed on CypCaps™ that had been frozen post-production for three months of storage at -80C. Samples were thawed to show that the cells inside the CypCaps™ were still alive and functional as well as free of infectious agents. Some of these tests were performed by Austrianova (cell count, biological activity of the cells, capsule integrity, label integrity), whereas others (sterility, pH measurement) were performed by contract labs.

About PharmaCyte Biotech

PharmaCyte Biotech, Inc. (PharmaCyte) is a biotechnology company developing cellular therapies for cancer and diabetes based upon a proprietary cellulose-based live cell encapsulation technology known as “Cell-in-a-Box®.” This technology will be used as a platform upon which therapies for several types of cancer and diabetes are being developed.

PharmaCyte’s therapy for cancer involves encapsulating genetically engineered human cells that convert an inactive chemotherapy drug into its active or “cancer-killing” form. For pancreatic cancer, these encapsulated cells are implanted in the blood supply to the patient’s tumor as close as possible to the site of the tumor. Once implanted, a chemotherapy drug that is normally activated in the liver (ifosfamide) is given intravenously at one-third the normal dose. The ifosfamide is carried by the circulatory system to where the encapsulated cells have been implanted. When the ifosfamide flows through pores in the capsules, the live cells inside act as a “bio-artificial liver” and activate the chemotherapy drug at the site of the cancer. This “targeted chemotherapy” has proven effective and safe to use in past clinical trials and results in little to no treatment related side effects.

PharmaCyte’s therapy for Type 1 diabetes and insulin-dependent Type 2 diabetes involves encapsulating a human cell line that has been genetically engineered to produce and release insulin in response to the levels of blood sugar in the human body. PharmaCyte is developing the use of genetically modified liver cells and stem cells, as well as beta islet cells, to treat diabetes. The encapsulation will be done using the Cell-in-a-Box® technology. Once the encapsulated cells are implanted in a diabetic patient, they will function as a “bio-artificial pancreas” for purposes of insulin production.
