Purple Biotech Reports Fourth Quarter and Full-Year 2024 Financial Results

Completed successful clinical trials for CM24 and NT219 oncology assets, demonstrating clinical benefits and identifying potential biomarkers CM24 is well positioned for personalized treatment, with planned biomarker-driven Phase 2b study based on serum biomarkers CEACAM1 and myeloperoxidase NT219 headed into Phase 2 head and neck cancer study in combination with pembrolizumab (anti-PD1) and in combination with cetuximab (anti-EGFR) CAPTN-3 tri-specific platform yields promising preclinical data, supporting its differentiated benefit and well positioning it in the multi-specific/engagers antibody space REHOVOT, Israel, March 10, 2025 (GLOBE NEWSWIRE) -- Purple Biotech Ltd. ("Purple Biotech" or "the Company") (NASDAQ/TASE: PPBT), a clinical-stage company developing first-in-class therapies that seek to overcome tumor immune evasion and drug resistance, today announced financial results for the three and twelve months ended December 31, 2024. “Our major value-driving milestones in 2024 included completing successful trials for both of our clinical-stage programs, CM24 and NT219, as well as expanding the body of exciting preclinical data for our CAPTN-3 tri-specific platform, supporting its differentiated benefit,” stated Gil Efron, Purple Biotech CEO. “CM24 met all of its efficacy endpoints in the randomized Phase 2 second-line pancreatic cancer trial, which also generated significant biomarker data that is now informing the design of our Phase 2b study for CM24, which we plan to initiate in the second half of 2025. As a biomarker-driven study, the Phase 2b study may evaluate CM24 across multiple oncology indications. “Earlier in 2024, we concluded the dose escalation study for NT219, demonstrating activity in combination with cetuximab, good safety profile, and determining the recommended Phase 2 dose. This enabled us to move forward with a Phase 2 study in head and neck cancer in collaboration with the University of Colorado, which we expect will commence patient enrollment in the first half of 2025. “We believe that our CAPTN-3 platform is well-positioned and differentiated in the T cell engagers (TCE) and multi-specific space, uniquely unleashes both innate and adaptive immune cells against the tumor, demonstrating synergistic effect of the T cell and NK cell activating arms. The unique NKG2A arm in the lead compound acts as a checkpoint inhibitor, enabling simultaneous NK and T cell activation, including effector subsets with high antitumor activity. We are excited about our CAPTN-3 collaboration with the Icahn School of Medicine at Mount Sinai. Our cash runway is expected to extend into mid-2026, providing us with the time to potentially deliver on more catalysts this year, in order to achieve our ambitious programs across all three assets,” Mr. Efron concluded. Q4 2024 and Recent Clinical & Corporate Highlights: CM24 Planned to Advance into Phase 2b Study Supported by Biomarker Data Positive final results from randomized Phase 2 study of CM24 in second line pancreatic cancerSerum CEACAM1 biomarker associated with 79% reduction in risk of death Purple Biotech reported positive final results from the randomized Phase 2 study of CM24, a humanized monoclonal antibody that blocks CEACAM1, in patients with second-line pancreatic ductal adenocarcinoma (PDAC). CM24, in combination with nivolumab and Nal-IRI/5FU/LV chemotherapy, demonstrated consistent improvements across all efficacy endpoints. The enhanced results in patients with elevated CEACAM1 and other serum markers suggest that selecting a biomarker-enriched patient population could further enhance CM24's efficacy, potentially positioning it as a treatment for multiple CEACAM1-expressing malignancies in line with its mechanism of action. A biomarker-enriched patient population analysis based on pretreatment serum CEACAM1 levels demonstrated a significant improvement in the treatment arm over the control arm, with a 79% reduction in risk of death (HR 0.21, p = 0.04), a median overall survival (OS) improvement of 5.1 months, and over 90% reduction in the risk of progression or death (HR < 0.1, p = 0.003), with a median progression-free survival (PFS) improvement of 2.9 months and improvement in the objective response rate (ORR) of 50% in the treatment arm compared to 0% in the control arm. Additional biomarker analysis revealed statistically significant results for 80% of the patients (24 out of 30) with serum CEACAM1 (5-16K pg/mL) or serum NET marker myeloperoxidase (MPO) (200-600 ng/mL) demonstrating 61% reduction in the risk of death (HR 0.39, p= 0.039) and 72% reduction in the risk of progression or death (PFS HR 0.28, P 0.006) following treatment with CM24 and nivolumab in combination with Nal-IRI/5FU/LV chemotherapy compared to same chemotherapy alone. In addition, median PFS increased by 2.2 months, and median OS increased by 2.4 months, from 5.5 months with chemotherapy alone to 7.9 months with the combination therapy. NT219 Advances into Phase 2 Head and Neck Cancer Trial Includes treatment arm of NT219 which we combine for the first time with pembrolizumab (Keytruda) immunotherapy, as well as expansion arm of NT219 combined with cetuximabCollaboration with University of ColoradoLatest patent in U.S. enhances global IP protection The Phase 2 study will evaluate the efficacy and safety of NT219 which we combine for the first time with standard-of-care checkpoint inhibitors, such as pembrolizumab (Keytruda), for the treatment of recurrent/metastatic squamous cell carcinoma of the head and neck (R/M SCCHN) and in combination with epidermal growth factor receptor (EGFR) blockers, such as cetuximab (Erbitux), which demonstrated activity in Purple Biotech’s Phase 1 dose escalation study. The Phase 2 study, expected to begin in the first half of 2025, is designed with two single-arm cohorts: one will evaluate NT219 in combination with pembrolizumab, and the other will evaluate NT219 in combination with cetuximab for the treatment of R/M SCCHN. Additionally, the study will explore potential biomarkers identified in a previous clinical study of NT219. The investigator-initiated Phase 2 trial is led by Dr. Antonio Jimeno, Professor and Director of the Head and Neck Cancer Program at the University of Colorado Anschutz Medical Campus. The U.S. Patent and Trademark Office issued a patent for NT219 used in combination with EGFR antibodies for treating cancer patients who have acquired resistance to EGFR therapies. This latest U.S. patent completes the geographic patent protection for NT219 used in combination with cetuximab in major markets, such as the United States, Europe, China and Japan. We believe this additional patent positions the Company well for the potential future commercialization of NT219. CAPTN-3 Tri-Specific Antibody Platform Preclinical Studies Advance Toward First-in-Human Clinical Trials New data presented at EORTC-NCI-AACR Symposium on Molecular Targets and Cancer TherapeuticsResearch collaboration with Icahn School of Medicine at Mount Sinai New data on CAPTN-3 were presented at the 36th European Organization for Research and Treatment of Cancer, National Cancer Institute, American Association for Cancer Research (EORTC-NCI-AACR) Symposium on Molecular Targets and Cancer Therapeutics. CAPTN-3 demonstrated sustained tumor regression in a triple-negative breast cancer in-vivo model, as well as dose-dependent activity and a synergistic effect of the engager arms in non-small cell lung cancer patient-derived explants. IM1240, Purple’s lead tribody candidate, demonstrated that cytokine release is 5T4-dependent and suppressed by the conditionally activated capping technology, suggesting a potentially beneficial safety profile. Purple Biotech entered into a Research Collaboration Agreement with the Icahn School of Medicine at Mount Sinai in New York to explore the immunoregulation of NK and T cells within the tumor microenvironment by CAPTN-3 multi-specific engagers, designed with the purpose of enhancing tumor-specific immunity against various cancer types. This collaboration offers an opportunity to deepen the understanding of tumor immune evasion mechanisms that CAPTN-3 uniquely addresses, with the goal of paving the way for effective treatments for many challenging tumor indications. Purple Biotech is working with Principal Investigator Amir Horowitz, PhD, and his team at Mount Sinai to validate the unique aspects of the CAPTN-3 design in a wide screen of patient-derived tumors, potentially providing new insights for overcoming resistance to standard frontline immunotherapies.

(NASDAQ/TASE: PPBT) is a clinical-stage company developing first-in-class therapies that seek to overcome tumor immune evasion and drug resistance. The Company's oncology pipeline includes CM24, NT219, and CAPTN-3. CM24 is a humanized monoclonal antibody that blocks CEACAM1, which supports tumor immune evasion and survival through multiple pathways. CEACAM1 on tumor cells, immune cells and neutrophils extracellular traps is a novel target for the treatment of multiple cancer indications. As proof of concept of these novel pathways, the Company completed a Phase 2 study for the treatment of pancreatic ductal adenocarcinoma (PDAC) with CM24 as a combination therapy with the anti-PD-1 checkpoint inhibitor nivolumab and chemotherapy, demonstrating clear and consistent improvement across all efficacy endpoints and the identification of two potential serum biomarkers. NT219 is a dual inhibitor, novel small molecule that simultaneously targets IRS1/2 and STAT3. A Phase 1 dose escalation study was concluded as a monotherapy and in combination with cetuximab, in which NT219 demonstrated anti-tumor activity in combination with cetuximab in second-line patients with recurrent and/or metastatic squamous cell carcinoma of the head and neck (R/M SCCHN). The Company is advancing NT219 into a Phase 2 study in collaboration with the University of Colorado, to treat R/M SCCHN patients in combination with cetuximab or pembrolizumab. The Company is advancing CAPTN-3, a preclinical platform of conditionally activated tri-specific antibodies, which engage both T cells and NK cells to induce a strong, localized immune response within the tumor microenvironment. The cleavable capping technology confines the compound's therapeutic activity to the local tumor microenvironment, thereby potentially increasing the anticipated therapeutic window in patients. The third arm specifically targets the Tumor Associated Antigen (TAA). The technology presents a novel mechanism of action by unleashing both innate and adaptive immune systems to mount an optimal anti-tumoral immune response. IM1240 is the first tri-specific antibody in development that targets the 5T4 antigen, which is expressed in a variety of solid tumors and is associated with advanced disease, increased invasiveness, and poor clinical outcomes. The Company's corporate headquarters are located in Rehovot, Israel. For more information, please visit https://purple-biotech.com/.
