REHOVOT, Israel, Nov. 21, 2023 (GLOBE NEWSWIRE) -- Purple Biotech Ltd. ("Purple Biotech" or "the Company") (NASDAQ/TASE: PPBT), a clinical-stage company developing first-in-class therapies that harness the power of the tumor microenvironment to overcome tumor immune evasion and drug resistance, today announced financial results for the third quarter and nine months ended September 30, 2023.

"We are pleased to report that we expect to complete patient enrollment in our Phase 2 randomized CM24 pancreatic cancer study soon, ahead of our previous plan and that might result in earlier than anticipated analysis of interim and top line overall survival (OS) data during 2024. The interim data look will occur in 2024 when sufficient progression free survival (PFS) and OS events are registered and enable a meaningful data interpretation for a larger number of patients. Recently reported biomarker data demonstrates CM24’s mechanism of action for this important indication in dire need of a more effective drug that prolongs survival,” stated Purple Biotech CEO, Gil Efron.

“Our Phase 1/2 dose escalation study of NT219 in head and neck cancer demonstrated initial activity at the dose level of 50 mg/kg. We continue dose optimization at a higher dose level and expect to report additional data during the first half of 2024 in parallel to preparing to enter a Phase 2 study.”

“With a cash runway that extends more than two years, through the second half of 2025, Purple Biotech is very well positioned to execute on multiple value-driving milestones. Moreover, we expect 2024 to be a year with major clinical data catalysts.”

Q3 2023 and Recent Corporate Highlights:

• CM24 Pancreatic Cancer Program Advances
  • Phase 2 enrollment ahead of schedule
  • Interim results for PFS and OS expected in H1 2024 with topline results expected in H2 2024
  • Biomarker data supporting MOA presented at A A CR

Patient enrollment in the Phase 2 study of CM24 was accelerated and the Company’s plan to enroll approximately 60 patients is expected to be completed soon, ahead of schedule. Since OS and PFS are event-based endpoints, a meaningful estimate of the endpoint can be achieved once sufficient events occur in the study arms. We expected this to happen in 2024 when enough PFS and OS events are registered and enable meaningful data interpretation for a larger number of patients. The acceleration allows the Company to reduce the total cost of the trial and to report, possibly earlier than expected, an interim OS analysis, the study’s primary endpoint, together with the analysis of PFS during 1H 2024 . The randomized Phase 2 study ( NCT04731467 ), in clinical collaboration with Bristol Myers Squibb (BMS), is evaluating CM24 in combination with BMS’s nivolumab plus chemotherapy in PDAC patients as a second line treatment as compared to chemotherapy alone.

New biomarker data for CM24 were presented at the American Association for Cancer Research (AACR) Special Conference: Pancreatic Cancer in a scientific poster titled "Phase 1 Study of CM24 in Combination with Nivolumab in Patients with Advanced Pancreatic Cancer - Survival, Exploratory Biomarkers and Effect on Neutrophil Extracellular Traps (NETs)". The study showed a high expression of CEACAM1, CM24’s target, on neutrophils and Neutrophil Extracellular Traps (NETs), and that there are enhanced levels of serum NETs in PDAC patients. This study demonstrated for the first time that CM24 treatment significantly reduced the level of NET marker in patients' serum, suggesting CM24’s novel mechanism of action (MOA) in treating pancreatic cancer.

• NT219 Positive Phase 1/2 Interim Results in Head & Neck Cancer
  • Anti-tumor activity with confirmed partial response s in highest , to date, dose cohort
  • Phase 2 study is being designed
  • Fortified IP protection with new patent

Initial anti-tumor activity was demonstrated at the 50mg/kg dose level of NT219 at 50mg/kg in combination with cetuximab in the Phase 1 dose escalation study. A dose-dependent increase in drug exposure of NT219 was reported and target engagement was observed in tumor samples, with 2 of the 4 evaluable recurrent and metastatic squamous cell carcinoma of the head and neck patients dosed at 50mg/kg demonstrated confirmed partial response.

A new patent was granted in China for NT219’s pharmaceutical composition. The new patent protects the method which prevents the conversion of NT219 from its active form to a less active form and supports maintenance of the active form during manufacturing, storage, and handling until administered to the patient.

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 NT219, CM24 and IM1240. NT219 is a dual inhibitor, novel small molecule that simultaneously targets IRS1/2 and STAT3. In a Phase 1/2 study of NT219, the Company is currently advancing it in a dose escalation as a monotherapy treatment of solid tumors, and in a dose escalation in combination with cetuximab for the treatment of recurrent and metastatic squamous cell carcinoma of the head and neck (SCCHN) or colorectal adenocarcinoma (CRC). These studies will be followed by an expansion phase of NT219 at its recommended Phase 2 level in combination with cetuximab in patients with recurrent and metastatic SCCHN. CM24 is a humanized monoclonal antibody that blocks CEACAM1, an immune checkpoint protein that supports tumor immune evasion and survival through multiple 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. IM1240 is a preclinical, conditionally-activated tri-specific antibody that engages both T cells and NK cells to mount a strong, localized immune response within the tumor microenvironment. The third arm specifically targets the Tumor Associated Antigen (TAA) 5T4 that is expressed in a variety of solid tumors and is correlated with advanced disease, increased invasiveness and poor clinical outcomes. IM1240 has a cleavable capping technology that confines the compound's therapeutic activity to the local tumor microenvironment, and thereby potentially increases the anticipated therapeutic window in patients. The Company's corporate headquarters are located in Rehovot, Israel. For more information, please visit https://purple-biotech.com/ .
