News release Jan 16 BioVaxys Developing DPX to be the Carrier of Choice for mRNA Vaccines, a market projected to grow to USD$48,000,000,000 by 2030* VANCOUVER, BC, Jan. 16, 2025 /CNW/ -- BioVaxys Technology Corp. (CSE: BIOV) (FRA: 5LB) (OTCQB: BVAXF) ("BioVaxys" or the "Company") highlights the potential for its DPX™ non-systemic immune educating platform to address the inherent limitations of lipid nanoparticles ("LNPs") for packaging and delivering mRNA and other polynucleotides. Continued development of DPX-mRNA formulations is one of the Company's objectives, with BioVaxys pursuing collaborations with companies and academic institutions that possess pipelines of promising tumor and virus-specific polynucleotide antigens.
BioVaxys' DPX™ technology ("DPX") is a patented delivery platform that can incorporate a range of bioactive molecules, such as mRNA/polynucleotides, peptides/proteins, virus-like particles, and small molecules, to produce targeted, long-lasting immune responses enabled by various formulated components. The DPX platform facilitates antigen delivery to regional lymph nodes and has been demonstrated to induce robust and durable T cell and B cell responses in pre-clinical and clinical studies for both cancer and infectious disease.
Data from proof-of-concept studies of DPX-mRNA formulations conducted in collaboration with leading RNA technology company Etherna and PCI Biotech demonstrate that DPX provides enhanced in vitro and in vivo stability of packaged mRNA, attracts a therapeutically unique subset of Antigen Presenting Cells (APCs) to the injection site for targeted uptake of mRNA by the immune system, and that immunization with DPX containing mRNA induces specific immune responses towards encoded antigens.
mRNA vaccines have emerged as a major scientific breakthrough in the development of immuno-therapeutics and have become the foundation for many new vaccine programs as the Covid pandemic accelerated the development of mRNA vaccines. The genetic sequence in mRNA vaccines instructs host cells to produce proteins to elicit immunological responses and prepare the immune system to fight infections or cancer cells.
During the pandemic, mRNA vaccines were proven to be highly effective, with billions of doses administered worldwide. However, their rapid development has led to challenges, particularly concerning relatively strong adverse reactions, including severe ones. Adverse reactions associated with current mRNA vaccines are primarily attributed to the LNPs that carry the mRNA. LNPs possess immunostimulatory properties and can spill out of the injection site, leading to systemic inflammatory responses. While these adverse reactions may be considered acceptable for a limited number of doses during a pandemic, a safer platform that allows multiple doses over a lifetime is desirable for the extension of mRNA vaccine applications to other applications.
For instance, mRNA that is packaged using LNP- based vaccine delivery systems enters cells through endocytosis and faces several limitations and challenges such as systemic delivery leading to rapid degradation by nucleases, macrophage phagocytosis removal, and renal filtration clearance. Due to their relatively short half-life, LNPs can show instability under in vivo conditions. Endosomal escape and removal through macrophages of lipid nanoparticles is possible without proper cellular uptake. Their instability and degradation affect their storage, delivery, and overall efficiency, compared with prior studies demonstrating that DPX™ recruits and activates unique subsets of antigen presenting cells ("APCs") to drive immunogenicity of antigens, exhibiting superior immune activation compared to aqueous and emulsion-based antigen delivery systems. The studies with Etherna and PCI Biotech demonstrated a preliminary, non-optimized, mRNA formulated in DPX with shelf-life integrity maintained for over the 14 days of the study, with mRNA formulated in DPX demonstrated to be stable for up to 14 days in vivo. It was also seen that DPX attracts a unique subset of antigen presenting cells (APCs) to site of injection for targeted uptake of mRNA, with immunization with DPX containing mRNA inducing a specific immune response towards encoded antigens.
BioVaxys President and Chief Operating Officer Kenneth Kovan says "The DPX platform is essentially a 'pipeline from a product' and will play a significant commercial role for the Company as an enabling technology for delivering nucleic acids and other antigens. DPX is ideal for mRNA delivery, as it remains localized and does not spill out from the injection site and has superior stability than LNPs. With better manufacturing economics than LNPs, it is generating interest from potential partners in the mRNA vaccine field."
BioVaxys has several issued patents related to DPX-mRNA formulations.

About BioVaxys Technology Corp.
BioVaxys Technology Corp. (www.biovaxys.com) is a clinical-stage biopharmaceutical company dedicated to improving patient lives with novel immunotherapies based on its DPX™ immune-educating technology platform and its HapTenix© 'neoantigen' tumor cell construct platform, for treating cancers, infectious disease, antigen desensitization for food allergy, and other immunological diseases. Through a differentiated mechanism of action, the DPX™ platform delivers instruction to the immune system to generate a specific, robust, and persistent immune response. The Company's clinical stage pipeline includes maveropepimut-S (MVP-S), based on the DPX™ platform, and is in Phase IIB clinical development for advanced Relapsed-Refractory Diffuse Large B Cell Lymphoma (DLBCL) and platinum resistant Ovarian Cancer. MVP-S delivers antigenic peptides from survivin, a well-recognized cancer antigen commonly overexpressed in advanced cancers, and also delivers an innate immune activator and a universal CD4 T cell helper peptide. MVP-S has been well tolerated and has demonstrated defined clinical benefit in multiple cancer indications as well as the activation of a targeted and sustained, survivin-specific anti-tumor immune response. BioVaxys is also developing DPX™+SurMAGE, a dual-targeted immunotherapy combining antigenic peptides for both the survivin and MAGE-A9 cancer proteins to elicit immune responses to these two distinct cancer antigens simultaneously, DPX™-RSV for Respiratory Syncytial Virus, DPX+rPA for peanut allergy prophylaxis, and BVX-0918, a personalized immunotherapeutic vaccine using its proprietary HapTenix© 'neoantigen' tumor cell construct platform for refractive late-stage ovarian cancer. BioVaxys common shares are listed on the CSE under the stock symbol 'BIOV', trade on the Frankfurt Bourse (FRA: 5LB), and in the US (OTCQB: BVAXF).
