Topline data from Phase 2 CM24 pancreatic cancer trial expected by the end of 2024

New CM24 biomarkers data presented during the third quarter of 2024 including two predicting serum biomarkers identified and associated with CM24 novel targets

CAPTN-3 tri-specific antibody platform data presented at the ENA Symposium October 2024

REHOVOT, Israel, Nov. 15, 2024 (GLOBE NEWSWIRE) -- Purple Biotech Ltd. ("Purple Biotech" or "the Company") (NASDAQ/TASE: PPBT), a clinical-stage company developing first-in-class therapies that overcome tumor immune evasion and drug resistance, today announced financial results for the three and nine months ended September 30, 2024.

“Marking what we believe to be the most significant value-driving event for Purple Biotech’s clinical programs to date, we are on track to complete CM24’s Phase 2 study in pancreatic cancer and report topline results by the end of this year,” stated Purple Biotech’s CEO, Gil Efron. “The interim Phase 2 CM24 data released so far demonstrated efficacy, and new biomarker data indicate potential to further improve outcomes in a future study through the use of one or more serum biomarkers for patient selection. This would position CM24 as a potentially promising CEACAM1 and Neutrophils Extracellular Trap (NET) targeted therapy. While we advance CM24 as a second line treatment for pancreatic cancer, we are planning to address additional unmet needs in other indications based on CM24’s demonstrated mechanism of action in our Phase 2 study. Our cash runway now extends into the fourth quarter of 2025. We continue to advance our clinical assets and believe we will be soon well positioned for partnerships across our pipeline.“

Q3 2024 and Recent Clinical & Corporate Highlights:

• Phase 2 CM24 pancreatic cancer study on track for conclusion with topline data expected in 2024: Serum biomarkers may improve outcomes in future studies

New positive biomarker findings for CM24, a multi-functional CEACAM1 inhibitor, were presented at the American Association for Cancer Research® (AACR) Special Conference on Advances in Pancreatic Cancer Research in a poster titled "Exploratory biomarker evaluation of the randomized Phase 2 cohort of CM24 in combination with nivolumab and chemotherapy in advanced/metastatic pancreatic cancer".

The summary of findings presented at AACR include the following:

• High CEACAM1 and low PDL1 expression in tumors, as well as their combination were identified as potential biomarkers associated with improved overall survival (OS) of pancreatic ductal adenocarcinoma (PDAC) patients (HR=0.1 and prolongation of 4.1 months in median OS, P = 0.01, for the combination), which support the CM24/nivolumab combined treatment

• Improved OS was demonstrated for patients with selected pretreatment serum neutrophil extracellular trap (NET) marker myeloperoxidase (MPO) levels (HR=0.38 and prolongation of 3.3 months in median OS, P = 0.1), with a similar trend in patients with NET-positive tumors

• The results presented in the poster propose NETs as a novel mechanism of action and a potential biomarker for CM24-based therapy

• New biomarker data supports the potential for future biomarker-guided studies and the exploration of CM24's efficacy in other cancers where the novel target CEACAM1 plays a key role in cancer progression and immune evasion.

More recent biomarker data specific to serum CEACAM1, associated with a 79% reduction in risk of death were announced by Purple Biotech in November 2024:

PDAC patients who had pretreatment serum CEACAM1 levels between 6K and 15K pg/mL demonstrated the best outcomes following treatment with CM24 and nivolumab in combination with irinotecan/fluoropyrimidine based chemotherapy compared to chemotherapy alone.

• Median progression free survival (PFS) of this group was 4.6 months (hazard ratio [HR] < 0.1, P = 0.003)

• Risk of death was reduced by 79% (HR = 0.21, P = 0.04)

• Median OS increased from 3.6 months with chemotherapy alone to 8.7 months with the combination therapy.

The Phase 2 randomized study is evaluating CM24 in combination with Bristol Myers Squibb’s PD-1 inhibitor nivolumab plus standard of care (SoC) chemotherapy as a second line treatment of patients with PDAC. In the experimental arms of the study patients were treated with CM24 plus nivolumab and one of two SoC chemotherapies, gemcitabine/nab-paclitaxel or Nal-IRI/5FU/LV, while patients in the control arms are administered with either respective chemotherapies alone. Sixty-three patients have been enrolled across 18 centers in the U.S., Spain and Israel. The gemcitabine/nab-paclitaxel-based part of the study was impacted by informative censoring of the control arm that led to an imbalance between the control and experimental cohorts, rendering this part of the study unsuitable for analysis; this part of the study has no impact on the CM24+nivolumab+Nal-IRI/5FU/LV portion of the study.

• NT219 Phase 2 study in head and neck cancer planned to commence H1 2025

A Phase 2 study of NT219, a first-in-class, small molecule dual inhibitor of IRS1/2 and STAT3, is planned to commence in the first half of 2025. The recommended Phase 2 dose of 100 mg/kg was achieved in the prior Phase 1/2 dose escalation study, which demonstrated anti-tumor activity at the target exposure level and was well tolerated in combination with cetuximab as a second line treatment of recurrent metastatic squamous cell carcinoma of the head and neck.

• CAPTN-3 tri-specific platform data presented at key molecular targets and cancer therapeutics conference

New data regarding Purple Biotech’s novel tri-specific antibody platform, 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 (the "Triple Meeting") in a poster titled "CAPTN-3: A novel platform of conditionally activated T cell and NK cell engagers". CAPTN-3 demonstrated sustained tumor regression in a triple negative breast cancer in-vivo model as well as dose dependent activity and synergistic effect of the engager arms in non-small cell lung cancer patient-derived explants. Purple Biotech’s lead tribody candidate, IM1240, demonstrated that cytokine release is 5T4-dependent and suppressed by the conditionally activated capping technology, suggesting a potentially beneficial safety profile of this tribody. The data further demonstrated additional tribodies, suggesting CAPTN-3’s plug and play platform capability. Purple Biotech continues to accumulate data supporting the benefit of dual engagement of both T cells and NK cells.

Non-IFRS Financial Measures.

This press release includes information about certain financial measures that are not prepared in accordance with International Financial Reporting Standards (“IFRS”), including adjusted operating loss and adjusted net loss. These non-IFRS measures are not based on any standardized methodology prescribed by IFRS and are not necessarily comparable to similar measures presented by other companies. Adjusted operating loss and adjusted net loss adjust for non-cash share-based compensation expenses and adjusted net loss also adjusts for non-cash financial instruments evaluation income. The Company's management and board of directors utilize these non-IFRS financial measures to evaluate the Company's performance. The Company provides these non-IFRS measures of the Company's performance to investors because management believes that these non-IFRS financial measures, when viewed with the Company's results under IFRS and the accompanying reconciliations, are useful in identifying underlying trends in ongoing operations. However, these non-IFRS measures are not measures of financial performance under IFRS and, accordingly, should not be considered as alternatives to IFRS measures as indicators of operating performance. Further, these non-IFRS measures should not be considered measures of the Company's liquidity. A reconciliation of certain IFRS to non-IFRS financial measures has been provided in the tables included in this press release.

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 CM24, NT219 and IM1240. CM24 is a humanized monoclonal antibody that blocks CEACAM1, that 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 a proof of concept of these novel pathways, the Company is advancing CM24 as a combination therapy with anti-PD-1 checkpoint inhibitors in a Phase 2 study for the treatment of pancreatic ductal adenocarcinoma (PDAC). The Company has entered into a clinical collaboration agreement with Bristol Myers Squibb for the Phase 2 clinical trials to evaluate the combination of CM24 with the PD-1 inhibitor nivolumab in addition to chemotherapy. 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 SCCHN (R/N SCCHN). The Company is advancing CAPTN-3, a preclinical platform of conditionally-activated tri-specific antibody that engages 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, and thereby potentially increases 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 5T4 expressed in a variety of solid tumors and is correlated 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/.
