PharmaCyte Biotech Closer to Submitting IND by Completing Encapsulation of Second Manufacturing Run of Clinical Trial Product
7 November 2019 - - US-based biotechnology company PharmaCyte Biotech, Inc. (OTCQB: PMCB) is closer to submitting an Investigational New Drug application to the US Food and Drug Administration, the company said.
PharmaCyte partner, Austrianova Singapore (Austrianova), has successfully completed encapsulation of the cells from PharmaCyte's Master Cell Bank in the second of two staggered and back-to-back manufacturing runs for the production of PharmaCyte's clinical trial product.
This product will be used for PharmaCyte's planned clinical trial in patients with locally advanced, inoperable pancreatic cancer.
Most of the work needed for PharmaCyte to submit an IND to the FDA has been completed. The rate limiting factor is and always has been for Austrianova to complete successfully two back-to-back manufacturing runs.
During PharmaCyte's recent shareholder update call, the company reported on Austrianova's work to encapsulate successfully PharmaCyte's genetically modified human cells that will be used to treat patients suffering from LAPC.
After months of extensive research and development by a team of experts from Austrianova and PharmaCyte, a total of eight different changes were made to the manufacturing process.
It was not until the eighth and final change was made that the encapsulated cells grew as well in Austrianova's manufacturing facility in Thailand as they grew at Austrianova's R and D facility in Singapore.
Once the recently encapsulated cells in this second of two manufacturing runs have completely filled the capsules, they will be placed into PharmaCyte's clinical trial syringes and then frozen.
A representative sample of those syringes will be thawed and undergo the FDA required "release testing."
All "release testing" related to safety of the encapsulated cells is being outsourced by PharmaCyte to independent third-party laboratories in Europe. All "release testing" related to functionality of the encapsulated cells is being handled by Austrianova at its GMP facility in Thailand.
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.
