BioVaxys Technology Corp. provided a corporate update on recent advancements of its vaccine platforms, and viral diagnostic and corporate objectives for 2021. BioVaxys announced that it has commenced the clinical development program for BVX-0918A, its haptenized tumor antigen vaccine for ovarian cancer. The Company plans to seek a compassionate use approval in the European Union for Stage III & Stage IV ovarian cancer, followed by submitting an IND in the US. BioVaxys is in discussions with its designated Contract Manufacturing Organization and anticipates the execution of a manufacturing contract in 1Q21. The Company plans to submit its Clinical Trial Application for BVX-0918A with the European Medicines Agency later this year. There are significant unmet therapeutic needs for ovarian cancer treatment. Over 240,000 women are currently diagnosed with ovarian cancer worldwide, and over 140,200 succumbed to the disease. Ovarian cancer is the leading cause of death from gynecologic malignancy in the United States. An estimated 21,750 new cases of ovarian cancer are expected in the United States in 2020 with 13,940 deaths. The case-to-fatality ratio is nearly three times that of breast cancer and makes ovarian cancer the deadliest gynecologic malignancy in developed countries. Like other cancers, the stage of disease is inversely proportional to survival. The 5-year relative survival rate in all stages of the disease is approximately 45%. However, ovarian cancer is usually asymptomatic in the early stages (Stage I and Stage II), and therefore about 80% of patients are diagnosed with advanced stage disease (stages III and IV). The 5-year survival rate for stage III and IV patients is approximately 29%. BioVaxys has developed its vaccine technology platforms based on the established immunological concept that modifying tumor or viral antigens with simple chemicals called haptens makes them more visible to the immune system. The process of haptenization "teaches" a patient's immune system to recognize and make target proteins more 'visible' as foreign, thereby stimulating an immune response. BioVaxys intends to develop its vaccine together with a "checkpoint inhibitor" that reduces or decreases the cellular function of an immune checkpoint gene or gene product. Checkpoint inhibitors are a type of drug that blocks proteins called 'checkpoints' that are made by some types of immune system cells, such as T cells and some cancer cells. These checkpoints help keep immune responses from being too strong, but also can sometimes keep T cells from killing cancer cells. When these checkpoints are blocked, T cells can more effectively kill cancer cells. BioVaxys' focus is on combinations of immune checkpoint inhibitors with its haptenized tumor antigen vaccine---primarily anti-CTLA4, anti-PD1, or PDL1 checkpoint antibodies---for treatment of ovarian cancer and other solid tumors. BioVaxys' rationale is that there is (1) a persistent unmet clinical need because the majority of ovarian cancer patients do not benefit from anti-checkpoint monotherapy; (2) evidence that not all patients make immune responses to their tumors; (3) evidence that immune responses to autologous tumor antigens can be induced by patient-specific vaccines; and (4) clinical evidence from the pre-checkpoint era that suggests survival can be positively impacted by such patient-specific vaccines. BioVaxys also recently completed its preclinical program for its SARS-CoV-2 vaccine candidate, BVX-0320, which included those studies suggested by the U.S. Department of Health and Human Services, Food and Drug Administration Center for Biologics Evaluation and Research "(CBER") in their published guidance on Development and Licensure of Vaccines to Prevent COVID-19. The FDA's non-binding Guidance is intended to assist in the clinical development and licensure of vaccines for the prevention of COVID-19, and reflect the Agency's current thinking on the issue. Conducted by Charles River Laboratories Inc. under contract with BioVaxys, the preclinical program which began in September 2020 evaluated the anti-virus immune response elicited by BVX-0320 in a controlled murine model by measuring the development of antibodies to the protein that binds the virus to human cells. Following two injections of BVX-0320 together with the immunological adjuvant, QS21, to 28 mice at four dosage levels, 96.4% developed positive antibody responses detected at week 6. The BioVaxys team also found that its haptenized SARS-CoV-2 s-spike vaccine activated CD4+ helper T-cells and CD8+ killer T-cells that express the activation markers, CD69 and CD25. This result indicates that immunization with BVX-0320 at two different dose levels of 3µg or 10µg stimulated immune system memory 'helper' T-cells as well as killer T-cells. CD4+ T-cells are crucial in achieving a regulated effective immune response to viral pathogens, and are central to adaptive immune responses. Generated following an immune response, memory 'helper' CD4+ T-cells retain information about the virus, which enables them to respond rapidly after viral exposure. CD8+ T-cells have the capacity to kill cells infected by the virus, thereby stopping viral replication in those cells. Under a BioVaxys-sponsored research collaboration with The Ohio State University Wexner School of Medicine, the OSU researchers used the available remaining mouse sera from the immune response assay to conduct a Plaque Reduction Neutralization Test, where the endpoint is reduction of plaques by 50%, where it was observed in a pooled sample that BVX-0320 elicited the production of neutralizing antibodies to SARS-CoV-2. Plaques are produced by infection of cultured human cells by a live SARS-CoV-2 virus. OSU is one of the few institutions that has the laboratory capability to study live SARS-CoV-2 virus.
