VANCOUVER, BC, April 25, 2022 /PRNewswire/ -- BioVaxys Technology Corp. (CSE: BIOV, FRA:5LB, OTCQB:BVAXF) ("BioVaxys" or "Company"), announced today that it has entered into an agreement with the Deaconess Research Institute ("DRI") to supply BioVaxys with surgically debulked tumors from Stage III/Stage IV ovarian cancer patients undergoing treatment at Deaconess Health System ("Deaconess").  DRI, based in Evansville, Indiana, is the clinical studies arm of Deaconess, a premier regional provider of health care services in the United States. Access to ovarian cancer tumor cells is a critical step enabling BioVaxys to validate the manufacturing process for BVX-0918, the Company's autologous haptenized tumor cell vaccine for late-stage ovarian cancer.

The standard of care for late-stage ovarian cancer often involves surgically debulking of the tumor mass.  The debulked tumor cells will be used to test and validate the tumor collection protocol, cryopackaging, cryopreservation, and supply chain logistics for BVX-0918 bioproduction.  Following shipment to BioElpida s.a. ("BioElpida"), the Company's bioproduction partner in Lyon, France, the tumor cells will then be used for process testing and manufacturing "dry runs" of BVX-0918, a major step leading to the completion of Good Manufacturing Process ("GMP") production, a requirement for the planned Clinical Trial Application ("CTA") with the European Medicines Agency ("EMA").   BioVaxys, together with its EU partner, ProCare Health of Barcelona, Spain, is preparing to launch a Phase I clinical study for BVX-0918 later this year.

BioElpida developed various tests and validation procedures needed to support GMP manufacturing, such as sterility testing for transport, hapten fixation, and cryopreservation solutions, as well as antibody generation, bioburden screening of the haptens, and endotoxin assays; access to debulked tumor means that BioElpida will begin the final stages of the vaccine production protocol and GMP validation. BioVaxys and BioElpida have also designed and fabricated a specialized shipping package which would cryopreserve the tumor sample while in transit from any hospital site to the BioElpida site.  

BioVaxys President & Chief Operating Officer Kenneth Kovan says,
"Having complied with the regulatory oversight involved in obtaining waste tumor samples, BioVaxys is now able to provide BioElpida with the materials required for finalizing the vaccine production protocol and performing process validation in the lead up to our planned CTA submission to the European regulator."

BioVaxys' vaccine platform is based on the established immunological concept that modifying surface proteins---whether they are viral or tumor---with haptens makes them more visible to the immune system. This process of haptenization "teaches" a patient's immune system to recognize and make target proteins more "visible" as foreign, thereby stimulating a T-cell mediated immune response.   BioVaxys' cancer vaccines are created by extracting a patient's own (autologous) cancer cells, chemically linking with a hapten, and re-injecting them into the patient to induce an immune response to proteins which are otherwise not immunogenic. Haptenization is a well-known and well-studied immunotherapeutic approach to cancer immunotherapy and has been clinically evaluated in both regional and disseminated metastatic tumors.

A first generation single-hapten vaccine invented by BioVaxys Co-Founder and Chief Medical Officer David Berd, MD, achieved positive immunological and clinical results in Phase I and Phase II human trials in over 600 patients with different tumor types, as well as having no observed toxicity in years of clinical study.  These studies were conducted under an FDA-reviewed IND. A first generation autologous, haptenized vaccine was also tested by Dr. Berd in women with advanced ovarian cancer who had ceased to respond to conventional chemotherapy.  The results were encouraging: In 24 patients, the median overall survival was 25.4 months with a range of 4.5-57.4 months; 8 patients survived for more than 2 years.  BioVaxys has enhanced the first-generation approach by utilizing two haptens ("bi-haptenization"), which the Company believes will yield superior results.

About BioVaxys Technology Corp.

Based in Vancouver, BioVaxys Technology Corp. (www.biovaxys.com) is a British Columbia-registered, clinical stage biotechnology company that is developing viral and oncology vaccine platforms, as well as immuno-diagnostics.  The Company is advancing vaccines for SARS-CoV-2, SARS-CoV-1, and a pan-sarbecovirus vccine based on its haptenized viral protein technology, and is planning a clinical trial of its haptenized autologous cell vaccine used in combination with anti-PD1 and anti-PDL1 checkpoint inhibitors that will initially be developed for Stage III/Stage IV ovarian cancer.  Also in development is CoviDTH®, a diagnostic for evaluating the presence or absence of a T cell immune response to SARS-CoV-2, the virus that causes COVID-19. BioVaxys has two issued US patents, and multiple US and international patent applications related to its cancer vaccines, antiviral vaccines, and diagnostic technologies.

Forward-looking statements in this news release relate to, among other things, completion of the murine model study, regulatory approval for a Phase I study of its BVX-0320 Vaccine Candidate in humans and the overall development of BioVaxys' vaccines, including any haptenized SARS-Cov-2 protein vaccine. There can be no assurance that such statements will prove to be accurate, and actual results and future events could differ materially from those expressed or implied in such forward-looking statements.

These forward-looking statements reflect the beliefs, opinions and projections on the date the statements are made and are based upon a number of assumptions and estimates, primarily the assumption that BioVaxys will be successful in developing and testing vaccines, that, while considered reasonable by the Company, are inherently subject to significant business, economic, competitive, political and social uncertainties and contingencies including, primarily but without limitation, the risk that BioVaxys' vaccines will not prove to be effective and/ or will not receive the required regulatory approvals. With regards to BioVaxys' business, there are a number of risks that could affect the development of its biotechnology products, including, without limitation, the need for additional capital to fund clinical trials, its lack of operating history, uncertainty about whether its products will complete the long, complex and expensive clinical trial and regulatory approval process for approval of new drugs necessary for marketing approval, uncertainty about whether its autologous cell vaccine immunotherapy can be developed to produce safe and effective products and, if so, whether its vaccine products will be commercially accepted and profitable, the expenses, delays and uncertainties and complications typically encountered by development stage biopharmaceutical businesses, financial and development obligations under license arrangements in order to protect its rights to its products and technologies, obtaining and protecting new intellectual property rights and avoiding infringement to third parties and their dependence on manufacturing by third parties.
