Purple Biotech Reports Second Quarter 2025 Financial Results

Platform validating preclinical data presented at EACR 2025 for CAPTN-3 tri-specific T cell engager show synergistic activity of the platform’s masked CD3, NKG2A, and tumor-associated antigen arms First CAPTN-3 trispecific antibody targeting novel tumor associated antigen, 5T4, advances toward first-in-human clinical trials, with IND submission expected in 2026 Positive Phase 2 data from CM24 study in biomarker-enriched pancreatic ductal adenocarcinoma (PDAC) reported at AACR 2025 NT219 Phase 2 study in head and neck cancer initiated in June 2025 REHOVOT, Israel, Aug. 06, 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, announced today financial results for the three months ended June 30, 2025. “Our CAPTN-3 tri-specific antibody platform is differentiated not only by its masked CD3 arm for conditional T cell activation, but also by the addition of an NKG2A arm for additional T cell and NK cell activation, and a third arm targeting the tumor-associated antigen. This approach is supported by other masked TCEs showing early safety and efficacy signals,” stated Purple Biotech CEO Gil Efron. “We are focusing our activities on advancing IM1240, our first CAPTN-3 antibody, through IND-enabling studies, with the goal of initiating a Phase 1 study in 2026. Additionally, we have now established a clear path forward for CM24 for its Phase 2b study, utilizing the predictive biomarkers we observed in the Phase 2 trial, and we are seeking partners or investment to support this next study.” Recent Clinical and Corporate Highlights: CAPTN-3 Tri-Specific Antibody Platform Showcased comprehensive in vivo and ex vivo data at EACR 2025, highlighting the synergistic activity of the platform’s masked CD3, NKG2A, and tumor-associated antigen arms Platform was spotlighted by Dr. Amir Horowitz at ASGCT 2025 for its approach to targeting the HLA-E/NKG2A axis to selectively activate NK and CD8+ T cells, potentially addressing treatment resistance First investigational new drug (IND) application from the CAPTN-3 platform, for IM1240 capped-CD3x5T4xNKG2A antibody, is expected to be submitted in 2026 CM24 (α-CEACAM1 monoclonal antibody) Final Phase 2 data for CM24 study presented at AACR Annual Meeting 2025 Statistically significant efficacy in biomarker subgroup analyses was observed: 78% reduction in risk of death and 81% reduction in risk of progression or death in patients with defined pretreatment ranges of serum or tumor CEACAM1 and 37.5% objective response rate (ORR) in this subgroup compared to 0% in the respective control group61% reduction in risk of death and 72% reduction in risk of progression or death in patients with defined pretreatment ranges of serum CEACAM1 or myeloperoxidase (MPO) and 31% ORR in this subgroup compared to 0% in the respective control group90% reduction in risk of death and 81% reduction in risk of progression or death in high tumor CEACAM1 and low PD-L1 combined positive score (CPS) subgroup The biomarkers identified in the CM24 Phase 2 study are planned to be used for patient selection in the Phase 2b study NT219 (IRS1/2 degrader and STAT3 blocker) Biomarker insights from the Phase 1 study were presented at AACR Annual Meeting 2025 Initiated NT219 Phase 2 study in recurrent and/or metastatic squamous cell carcinoma of the head and neck (R/M SCCHN) to evaluate NT219 in combination with pembrolizumab (Keytruda) or cetuximab (Erbitux) Phase 2 study is led by Dr. Antonio Jimeno, Professor and Director of the Head and Neck Cancer Program, and Principal Investigator Dr. Alice Weaver, at the University of Colorado Anschutz Medical Campus Financial Results for the Three Months Ended June 30, 2025 Research and Development Expenses were $0.6 million for the three months ended June 30, 2025, reflecting a decrease of $1.8 million, or 76.9%, from $2.4 million in the same period of 2024. The decrease was primarily due to reduced costs associated with the CM24 Phase 2 study. General and Administrative Expenses were $0.7 million for the three months ended June 30, 2025, compared to $1.1 million in the same period of 2024, representing a decrease of $0.4 million, or 36.0%, mainly due to a $0.2 million decrease in a non-cash expense and $0.2 million reduction in cash and non-cash salaries and related expenses. Operating Loss was $1.2 million for the three months ended June 30, 2025, a decrease of $2.2 million, or 64.3%, compared to $3.5 million in the same period of 2024, mainly due to the decrease in the CM24 Phase 2 study expenses. Adjusted Operating Loss (as reconciled below) was $1.2 million for the three months ended June 30, 2025, a decrease of $2.0 million, compared to $3.2 million in the same period of 2024, primarily due to the decrease in the CM24 Phase 2 study expenses. Finance Income, net was $0.1 million for the three months ended June 30, 2025, compared to $1.0 million in the same period of 2024, representing a decrease of $0.9 million, primarily attributable to a decrease in non-cash gain resulting from the revaluation of outstanding warrants. Net Loss was $1.1 million, or $0.40 per basic and diluted ADS for the three months ended June 30, 2025, compared to a net loss of $2.4 million, or $1.80 per basic and diluted ADS, in the same period of 2024. The decrease in net loss was mainly due to the $2.2 million decrease in operating expenses and $0.9 million decrease in finance income, net. As of June 30, 2025, Purple Biotech had cash and cash equivalents and short-term deposits of $5.6 million. The Company cash runway is expected into the third quarter of 2026. About Purple Biotech Purple Biotech Ltd. (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 CAPTN-3, CM24 and NT219. 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. 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 neutrophil 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 and other potential tissue 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). A Phase 2 study in collaboration with the University of Colorado Anschutz Medical Campus, to treat R/M SCCHN patients with NT219 in combination with cetuximab or pembrolizumab was initiated. The Company’s corporate headquarters are located in Rehovot, Israel. For more information, please visit https://purple-biotech.com/.
