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.

To date, XPOVIO® has already been included in national health insurance or reimbursement schemes in South Korea, the mainland of China, Australia and Singapore, and is expected to achieve national reimbursement coverage in more APAC markets. XPOVIO® has been approved for multiple indications in nine markets across the APAC region. Antengene has submitted a new drug application (NDA) for XPOVIO® in Indonesia with approval expected in the second half of 2024. SHANGHAI and HONG KONG, Oct. 17, 2024 /PRNewswire/ -- Antengene Corporation Limited ("Antengene", SEHK: 6996.HK), a leading innovative, commercial-stage global biopharmaceutical company dedicated to discovering, developing and commercializing first-in-class and/or best-in-class medicines for hematologic malignancies and solid tumors, today announced that the South Korean Ministry of Food and Drug Safety (MFDS) has approved a supplemental New Drug Application (sNDA) for XPOVIO ® (selinexor) in combination with bortezomib and dexamethasone for the treatment of adult patients with multiple myeloma (MM) who have received at least one prior therapy. Prior to the recent approval, XPOVIO ® has been approved for two indications in South Korea that are: in combination with dexamethasone for the treatment of adult patients with relapsed or refractory MM (R/R MM); and as a monotherapy for the treatment of adult patients with relapsed or refractory diffuse large B-cell lymphoma (R/R DLBCL). In July 2024, XPOVIO ® was included into the reimbursement drug list in South Korea, thus became the first XPO1 inhibitor approved for public insurance coverage in the country. With a novel mechanism of action, XPOVIO® is the world's first approved orally-available, selective XPO1 inhibitor, which has already been approved in nine countries and regions in APAC and included in the national insurance schemes in South Korea, the mainland of China, Australia, and Singapore. This recent approval for XPOVIO® in South Korea will bring another innovative therapy to the clinical management of MM patients in South Korea, benefiting countless patients and families. While bringing XPOVIO® to more APAC markets, Antengene is also striving to expand the indications of XPOVIO®. Leveraging the drug's novel mechanism of action, Antengene is currently developing multiple combination regimens of XPOVIO® for the treatment of various indications including myelofibrosis (MF), and endometrial cancer. About XPOVIO® (selinexor) XPOVIO® is the world's first approved orally-available, selective inhibitor of the nuclear export protein XPO1. It offers a novel mechanism of action, synergistic effects in combination regimens, fast onset of action, and durable responses. By blocking the nuclear export protein XPO1, XPOVIO® can promote the intranuclear accumulation and activation of tumor suppressor proteins and growth regulating proteins, and down-regulate the levels of multiple oncogenic proteins. XPOVIO® delivers its antitumor effects through three mechanistic pathways: 1) exerting antitumor effects by inducing the intranuclear accumulation of tumor suppressor proteins; 2) reducing the level of oncogenic proteins in the cytoplasm by inducing the intranuclear accumulation of oncogenic mRNAs; 3) restoring hormone sensitivity by activating the glucocorticoid receptors (GR) pathway. To utilize its unique mechanism of actions, XPOVIO® is being evaluated for use in multiple combination regimens in a range of indications. At present, Antengene is conducting multiple clinical studies of XPOVIO® in the mainland of China for the treatment of relapsed/refractory hematologic malignancies and solid tumors (3 of these studies are being jointly conducted by Antengene and Karyopharm Therapeutics Inc.

VIP943 demonstrates promising safety and tolerability and achieves two complete responses to date in Phase 1 dose-escalation study, reinforcing the program’s potential and validating the VersAptx™ Platform technology Vincerx focusing resources on continued development of VIP943 Expected cash runway into early 2025 Management to host webcast and Q&A today at 5:00 PM EDT to review pipeline and corporate updates, followed by commentary from key opinion leader Dr. M. Yair Levy Oct. 07, 2024 -- Vincerx Pharma, Inc. (Nasdaq: VINC), a biopharmaceutical company aspiring to address the unmet medical needs of patients with cancer through paradigm-shifting therapeutics, announced two complete responses in the ongoing first-in-human, Phase 1 dose-escalation study of VIP943, the Company’s next-generation antibody-drug conjugate (ADC) being evaluated in relapsed/refractory acute myeloid leukemia (AML), higher-risk myelodysplastic syndrome (HR-MDS), and B-cell acute lymphoblastic leukemia (B-ALL). The Company also provided pipeline and corporate updates. The ongoing Phase 1 dose-escalation study of VIP943 has enrolled 22 patients to date across several escalating dose cohorts (0.2 to 1.3 mg/kg once weekly). These 22 patients represent a ‘hard-to-treat’ salvage population, which rarely responds to monotherapy. Nine patients (six AML; three HR-MDS) have received at least three doses of an efficacious dose of VIP943 (i.e., ≥1.0 mg/kg). Of these nine patients, four (44%) remain on study. So far, one patient with relapsed AML has achieved complete remission with incomplete hematologic improvement (CRi) and one patient with HR-MDS has achieved complete remission with limited count recovery (CRL) based on international consensus response criteria. These response criteria are widely recognized as an approvable benchmark in AML and MDS studies, further underscoring the significance of these early results. “We are excited by the emerging data from our Phase 1 study of VIP943, showing clinical responses in difficult-to-treat patients," said Ahmed Hamdy, M.D., Chief Executive Officer of Vincerx. "We believe these promising clinical responses highlight the potential of VIP943 as a best-in-class therapy for CD123+ hematologic malignancies and validate our VersAptx platform’s ability to create safer, more effective bioconjugates by overcoming the challenges of historical ADCs.” As of August 2024, VIP943 has shown favorable safety and tolerability, with no dose-limiting toxicities reported in 22 patients. Serious adverse events (SAEs) have been consistent with expectations for this patient population. The most common SAEs included pneumonia (three patients, 14%), and cellulitis and febrile neutropenia (two patients each, 9%). Only one patient (5%) experienced a drug-related SAE (Grade 3 diarrhea). Target engagement (i.e., receptor occupancy) has been demonstrated by binding of VIP943 to CD123+ peripheral blood blasts from patients with AML from the Phase 1 study. Maximal receptor occupancy of 84% was achieved in the highest dose cohort (1.3 mg/kg). Across all the cohorts, receptor occupancy was retained for less than 96 hours. Concurrent decreases in CD123+ peripheral blood blasts were also observed after dosing. These pharmacodynamic (PD) markers show that VIP943 is binding to and eliminating CD123+ malignant cells. Preliminary pharmacokinetic (PK) data continues to show low release of payload (≤1% in plasma). The half-life of VIP943 is less than 96 hours, and no accumulation occurs with repeat dosing. These PK and PD results have prompted evaluation of twice weekly dosing of VIP943 as a potential “induction” regimen. Enrollment in the once weekly and twice weekly dosing cohorts is ongoing. Dr. Hamdy continued, “Our initial clinical results demonstrate that VersAptx is a next-generation platform that overcomes key challenges associated with traditional ADCs. The PK profile shows that our linker is stable, cleaving exclusively inside cells without extracellular degradation. Our PD results coupled with clinical responses confirm the payload effectively kills cancer cells in peripheral blood and bone marrow without harming nearby healthy tissue. This innovative design with proof-of-concept in Phase 1 reinforces our confidence in VersAptx as a transformative platform for ADC development.” The company anticipates providing another data update on the ongoing Phase 1 VIP943 study by the end of the year. Dr. M. Yair Levy, Director of Hematologic Malignancies Research at Texas Oncology added, "Although this is still early data, VIP943 is clearly differentiated from other ADCs, particularly with its favorable safety profile. We’re not seeing neutropenia as a dose-limiting toxicity, which is encouraging and may allow the drug to move into earlier lines of therapy in combination. I look forward to the continued development of VIP943 and its potential to improve treatment options for patients with CD123+ malignancies.” VIP236 is Vincerx’s first-in-class small molecule drug conjugate (SMDC) being evaluated in an ongoing first-in-human, Phase 1 dose-escalation study as a monotherapy in patients with advanced solid tumors. As of September 2024, 29 patients have been enrolled. Of these patients, 20 were evaluable per-protocol for response from the every 2- or 3-week schedule; nine of 20 patients had stable disease for a disease control rate of 45%. In addition, one of these subjects has been on treatment for over 300 days and four additional patients were on study for more than 120 days, demonstrating promising monotherapy duration of response in patients with advanced cancer. VIP236 continued to show a favorable safety and tolerability profile in these 29 patients, with no instances of the dose-limiting side effects commonly associated with camptothecins, such as life-threatening diarrhea, severe stomatitis/mucositis, or interstitial lung disease. These results support the potential role of VIP236 as a strong combination agent for the treatment of advanced cancers. Considering the promising VIP236 clinical data, the Company intends to pursue a strategic partner to champion its future development for the benefit of patients. “We've made significant progress in identifying an effective dose and schedule. We believe it is now crucial to study VIP236 in the right patient population, which could include triple-negative breast cancer and gastric cancer, where camptothecins are used, especially in combination with other anticancer agents,” added Dr. Hamdy. By transitioning VIP236 to a partnering asset, the Company plans to streamline its operations and focus its efforts on the continued development of its lead ADC, VIP943. Enitociclib, a highly selective CDK9 inhibitor, is currently being evaluated in a Phase 1 dose-escalation study in combination with venetoclax and prednisone for relapsed/refractory diffuse large B-cell lymphoma (DLBCL) and peripheral T-cell lymphoma (PTCL), in collaboration with the National Institutes of Health (NIH). As of September 2024, the study reported four partial responses (PRs) in seven patients (57% overall response rate), including one patient with double hit lymphoma (DH-DLBCL) and three patients with PTCL. All responses occurred in patients considered refractory by SCHOLAR-1 criteria and included one patient with prior CAR-T therapy. The study is currently enrolling in the third dose level (enitociclib 30 mg [efficacious dose] and venetoclax 600 mg) with two patients enrolled to date. Additionally, in a separate Phase 1 study of enitociclib as a monotherapy (30 mg), one patient with transformed follicular lymphoma achieved a metabolic PR. As of September 2024, this patient remains on enitociclib monotherapy after more than 26 months. Overall, these clinical results continue to show the promising safety, tolerability, and efficacy of enitociclib for the treatment of relapsed/refractory lymphoma. The Company is actively focused on finding a strategic partner to continue the development of this asset. VIP236, the first-in-class SMDC from the VersAptx Platform, consists of an αvβ3 integrin binder, a neutrophil elastase linker cleaved in the tumor microenvironment, and a camptothecin payload optimized for high permeability and low active efflux. VIP236 was designed to deliver its payload to advanced/metastatic solid tumors that express αvβ3. VIP236 is being evaluated in a first-in-human, Phase 1 dose escalation study in patients with advanced malignancies (NCT05712889). VIP943, the first ADC from the VersAptx platform, consists of an anti-CD123 antibody, a unique linker cleaved intracellularly by legumain, and a novel kinesin spindle protein inhibitor (KSPi) payload enhanced with Vincerx’s CellTrapper™ technology. Vincerx’s proprietary effector chemistry (linker + payload) was designed to reduce non-specific release of the payload and ensure payload accumulation in cancer cells versus healthy cells. The increased therapeutic index has the potential to address challenges associated with many ADCs by improving efficacy and reducing severe toxicities. VIP943 is being evaluated in a Phase 1 dose-escalation trial in patients with relapsed/refractory AML, HR-MDS, and B-ALL who have exhausted standard therapeutic options (NCT06034275). Enitociclib, a highly selective CDK9 inhibitor, is currently being evaluated in a Phase 1 dose-escalation study (NCT05371054) in combination with venetoclax and prednisone for DLBCL and PTCL, in collaboration with the NIH. Enitociclib has demonstrated favorable safety and PK, with significant clinical benefits across various indications, including durable complete metabolic remissions in patients with double-hit (DH)-DLBCL and stable disease in solid tumors, notably in ovarian cancer, suggesting promising potential for future combination studies. VersAptx is a versatile and adaptable next-generation bioconjugation platform. The modular nature of this innovative platform allows the combination of different targeting, linker, and payload technologies to develop bespoke bioconjugates that address different cancer biologies.
