Study Results Position Company to Target Segments of $270B+ Multi-Billion Dollar Drug Delivery Systems Market1 VANCOUVER, BC, Oct. 31, 2024 /PRNewswire/ -- BioVaxys Technology Corp. (CSE: BIOV) (FRA: 5LB) (OTCQB: BVAXF) ("BioVaxys" or the "Company") highlights studies showing that its novel immune educating delivery platform, DPX™, recruits and activates unique subsets of antigen presenting cells ("APCs") to drive immunogenicity of antigens, and exhibits superior immune activation compared to aqueous and emulsion-based antigen delivery systems. With cancer vaccines, the successful eradication of tumors relies on the persistent delivery of antigenic APCs to prime potent, antigen specific, cytotoxic T cells. Current peptide antigen delivery methods include using either water-based formulations which provide short exposure of peptides to immune cells, or oil-in-water emulsions that provide longer peptide exposure but that can elicit dysfunctional T cell phenotypes. In contrast, BioVaxys' DPX technology is a non-aqueous, lipid-in-oil, immune-educating therapeutic delivery platform that keeps the antigen cargo at the site of injection, ensuring that uptake of the DPX-encapsulated cargo is an active process driven by the APCs across time. In a study done in collaboration with Dalhousie University of Halifax, Nova Scotia, DPX was compared to aqueous and emulsion-based formulations to evaluate the dynamics of immune cell recruitment to the site of injection, antigen consumption, and trafficking by immune cells. Immune cell composition and antigen uptake at the injection site were assessed by multi-parameter flow cytometry and confocal microscopy using model peptide antigens administered in mice. Antigen-specific immune responses were assessed by interferon-gamma (IFN-γ)-based Enzyme-Linked Immunospot (ELISpot) assay to measure IFN-γ, the presence of which plays a crucial role in activating the immune system. The ELISpot assay is a sensitive method for measuring the number of cells that produce cytokines or antibodies in response to an antigen. "BioVaxys is at the forefront of a significant shift in the drug delivery landscape," James Passin, CEO of BioVaxys, stated, "These groundbreaking study results validate our strategic position in an important segment of the multi-billion drug delivery market. DPX not only outperforms current antigen delivery solutions but also demonstrate inherent immune-activating properties, opening up significant revenue potential across multiple market segments." The study results showed that aqueous formulations were poorly able to retain lymphocytes at the injection site and consequently did not elicit a detectable IFN-γ ELISpot response. Both DPX and the oil emulsion were superior in recruiting APCs to the injection site and inducing antigen-specific immune responses, and with significant increases in immune cell infiltration detected as early as 2 days post DPX injection. However, a significant difference between DPX and oil emulsion was that antigen presentation driven by the DPX platform resulted in activation of more critical markers of T cell subsets than emulsion. An additional and highly significant finding is that recruitment and activation of these T cell subsets by DPX was evident regardless of whether an antigen was contained as cargo in DPX, indicating that DPX on its own has immune system activating properties. Kenneth Kovan, President and Chief Operating Officer at BioVaxys, stated "We know that compared to DPX remaining at the injection site, emulsion-based and aqueous formulations leach cargo into surrounding tissues. These findings further highlight the quantitative, qualitative, and temporal differences in immune cell recruitment by DPX and two common delivery platforms and show the character of the immune response triggered by the DPX platform via activation of T cell subsets with intrinsically higher capacity for antigen uptake, presentation, and activation." BioVaxys is planning to present additional data in early December on the unique characteristics of DPX 1Drug Delivery Devices Market Size, Share & Trends Analysis Report By Application (Oncology, Infectious Diseases), By Route Of Administration (Oral, Transdermal, Injectable), By End-use, By Region, And Segment Forecasts, 2024 – 2030, Grand View Research About BioVaxys Technology Corp.

BOSTON, Oct. 31, 2024 /PRNewswire/ -- In a remarkable development for cancer research, patients with advanced-stage cancer have benefited from SUPLEXA, a personalized treatment that trains the patient's own immune cells to fight cancer. "Cancer often gains the upper hand by suppressing the immune system. Our approach flips the script: we isolate immune cells from this suppressive environment, we reactivate their inherent cancer-fighting abilities in a laboratory, and return them back to the patient", said Dr Frank Borriello, Founder and CEO of Boston-based Alloplex Biotherapeutics[1]. While the science behind SUPLEXA is sophisticated, the process for patients and clinicians is surprisingly straight-forward. A single 50 mL blood draw from the patient is all it takes to develop a complete course of SUPLEXA therapy. With nothing more than standard lab equipment, the patient's white blood cells are isolated and 'trained' outside the body (ex vivo) using Alloplex's proprietary ENLIST immune cell training technology. About a month later, the enhanced blood cells are infused into the patient, where they not only seek out and destroy rogue cancer cells — that had, until then, evaded the immune system — but improve the overall immune health of the patient. Full results of the first-in-human trial[2] will be released at the 2024 SITC conference in November. The Australian study showed no treatment-related serious adverse events — unsurprising, given that SUPLEXA is made from the patients' own immune cells that have simply undergone a training process to improve their functionality before being reintroduced to the patient. Remarkably, and in addition to its strong safety profile, SUPLEXA transformed the lives of patients with various cancer types. Its most striking results were observed in patients with a specific type of advanced colorectal cancer (CRC) and renal cell carcinoma (RCC). Three CRC patients derived significant clinical benefit: one achieved a complete response (CR), another a partial response (PR) and another stable disease (SD). "Many of these patients sustained a strong clinical response for up to two years," said Dr. Borriello. Of the ten RCC patients, one achieved a partial response (PR) and six achieved stable disease (SD) while only 3 had progressive disease (PD). Patients with other solid tumors, including melanoma, breast and lung cancer, also demonstrated long-term SD with SUPLEXA. While quality of life assessments were not formally captured in this study, patients reported improvements in their well-being, a reduction in pain and improved symptom control. For the participating patients who had exhausted all standard treatment options, "SUPLEXA has been a remarkable experience," said Principal Investigator, Assoc. Professor Rohit Joshi[3], who led the first-in-human study across three sites in Australia[4]. "It's also allowed them to continue with their normal lives, have a vacation, take up new hobbies and spend more time with family and friends," said Assoc. Prof. Rohit Joshi. FDA Opens Door to Proceed With encouragement from the FDA to proceed with an Investigational New Drug (IND) submission, Alloplex Biotherapeutics plans to initiate Phase 2 clinical trials of SUPLEXA in early 2025. The trial will combine SUPLEXA with immune checkpoint inhibitors (ICIs) in patients with a specific type of colorectal cancer. The goal is to test, in a controlled clinical setting, whether SUPLEXA's complementary mechanisms can enhance patient outcomes by amplifying the effectiveness of ICIs, which are the standard of care for this type of cancer. Notes: Alloplex Biotherapeutics is a private Boston-based company founded in 2016 with a singular focus on developing its ENLIST immune cell training platform for cancer. SUPLEXA cells represent the first candidate to emerge from this platform that harnesses and amplifies the innate capabilities of the immune system, Full clinical and scientific results of the trial will be presented at the Society for Immunotherapy of Cancer 'SITC' meeting in Houston, Texas in early November 2024. Abstracts #378 and #678 will be presented in the Immune Engineering Workshop and at the Annual Meeting. Assoc. Professor Rohit Joshi, MBBS, MD, FRACP, FACP, FRCP, is a highly published and renowned medical oncology consultant. He is an Associate Professor at the University of South Australia and University of Adelaide; and Director of Cancer Research SA ('CRSA'). The company's first-in-human clinical trial enrolled 35 patients with a variety of advanced cancer types. It was an open label, single-agent, basket study across three clinical sites in Australia and concluded in June 2024. The three sites in Australia where the SUPLEXA trial was carried out are: (1) Cancer Research SA ('CRSA') in Adelaide, South Australia; (2) Southern Oncology Research United ('SOCRU') in Adelaide, South Australia, and (3) Greenslopes Private Hospital / Gallipoli Medical Research Foundation, in Brisbane, Queensland.
