    LAGUNA HILLS, CA, July 22, 2021 (BUSINESS WIRE) — PharmaCyte Biotech, Inc. (OTCQB: PMCBD), 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 three independent industry publications mention PharmaCyte and/or its past clinical trials and their contributions to prior and future work in the treatment of pancreatic cancer.

    PharmaCyte’s Chief Executive Officer (CEO), Kenneth L. Waggoner, commenting on the Company’s expected uplist to Nasdaq said, “As we head into the ninth day of a required 10 days of trading following a reverse stock split, we remain above the price requirement necessary to complete our list of criteria for the expected uplist. Our hope is that PharmaCyte will be trading on the highly respected platform and will become a Nasdaq listed company as early as next week.”

    Waggoner continued, “With a number of recent well-respected scientific review publications supporting the approach that our technology uses as a promising treatment for pancreatic cancer, it is a validation, of sorts, of our approach and technology against the disease by independent scientists.”

    Three recently published high profile international medical and scientific review articles have highlighted PharmaCyte’s pancreatic cancer treatment. The articles mention (i) the treatment’s use in clinical trials to develop a cellular microencapsulation technology to treat pancreatic cancer; (ii) the use of prodrugs in its treatment; and (iii) the treatment’s role in improving the pancreatic cancer treatment landscape.

    First, the respected scientific journal, Drug Discovery Today, published an article by a Spanish academic group, known for their expertise in the field of cellular encapsulation titled, “Cell microencapsulation technologies for sustained drug delivery: Clinical trials and companies.” This publication stresses that the Cell-in-a-Box® technology has been tested for years at the preclinical level as well as in two previously successful human clinical trials.

    The authors summarize the results of the trials, essentially stating that microencapsulated cells that overexpressed cytochrome P450 2B1 (CYP2B1), which metabolizes the chemotherapy prodrug ifosfamide, transformed it into its active metabolites. These microencapsulated cells were implanted in 27 patients with pancreatic cancer. By placing the microencapsulated cells close to the area to be treated, a more focused therapy is obtained and, thus, better results are expected with lower doses of the chemotherapy prodrug ifosfamide.

    In the first Phase 1/2 clinical trial using a 1 g/m2/ per day dose of ifosfamide, the median survival of patients was doubled and only one of the patients had treatment-related adverse effects. In a second Phase 2 clinical trial, the prodrug ifosfamide per day dose was increased to 2 g/m2/day. The results showed greater severe adverse effects, but the efficacy profile was similar to the results from the Phase 1/2 clinical trial. The publication notes that PharmaCyte is “continuing with these promising clinical trials and are currently conducting the tests required by the regulatory agencies to begin a Phase 2b clinical trial as soon as possible.” (Lopez-Mendez et al., 2021, Drug Discovery Today 26, 852-861)

    The sentiment expressed by Lopez-Mendez et al. is echoed in another recent review from the World Journal of Gastroenterology, “Room for improvement in the treatment of pancreatic cancer: Novel opportunities from gene targeted therapy,” from the Department of Gastroenterology, Addenbrooke’s Hospital, Cambridge, U.K. This particular review specifically states, “The cytochrome P450/ifosfamide system proof of concept from pre-clinical studies has been used to conduct Phase 1 and Phase 2 clinical trials in pancreatic cancer patients with phenomenal success (improvement of 1-year survival by 3-fold and median survival doubled)” (Galanopoulos et al., 2021, World J Gastroenterol 27, 3568-3580).

    The third publication supports the activity of PharmaCyte’s pancreatic cancer treatment titled, “Prodrugs and prodrug-activated systems in gene therapy.” This publication that appeared in the

    high impact journal Molecular Therapy states, “At a dose of 1 g/m2, ifosfamide was well tolerated by all patients in the first part of the trial, with regression of tumors in four patients and stable disease in the other participants.” (Sheikh et al., 2021, Molecular Therapy 29, 1716-1728)

    PharmaCyte’s CEO added, “The positive assessments of our technology and its use in the treatment of pancreatic cancer by the authors of these key publications, underscore how important it is for us to receive the U.S. Food and Drug Administration’s approval to start our clinical trial in locally advanced and inoperable pancreatic cancer.”

    About PharmaCyte Biotech

    PharmaCyte Biotech, Inc. 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 is being 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, the chemotherapy prodrug ifosfamide that is normally activated in the liver 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 prodrug ifosfamide at the site of the cancer. This “targeted chemotherapy” has proven effective and safe to use in past clinical trials and we believe 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 liver 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 also considering the use of genetically modified stem cells to treat diabetes. The encapsulation of the cell lines will be done using the Cell-in-a-Box® technology. Once the encapsulated cells are implanted in a diabetic patient, we anticipate that they will function as a “bio-artificial pancreas” for purposes of insulin production.
