Purple Biotech Reports First Quarter 2023 Financial Results and Provides Business Update
Expands pipeline with acquisition of new tri-specific antibodies
Data readouts for two lead clinical programs expected in 2023
REHOVOT, Israel, May 16, 2023 (GLOBE NEWSWIRE) -- Purple Biotech Ltd. (“Purple Biotech” or “the Company”) (NASDAQ/TASE: PPBT), a clinical-stage company developing first-in-class, effective and durable therapies that harness the power of the tumor microenvironment to overcome tumor immune evasion and drug resistance, today announced financial results for the three months ended March 31, 2023.
"We are optimistic about Purple Biotech's prospects during 2023 and beyond, as the year started off with an important acquisition that brings us a powerful new platform for tri-specific antibodies, complementing our two ongoing clinical programs, both of which are expected to read out during 2023," said Isaac Israel, Acting Chief Executive Officer of Purple Biotech.
"We saw significant progress with both of our ongoing investigational compounds. For CM24, we expanded the Phase 2 clinical trial while maintaining the anticipated enrollment rate. We completed the enrollment of patients in the safety run-in arms and dosed the first patients in the randomized arms, which we anticipate will allow us to obtain further meaningful clinical data this year. We also made significant advancements in our efforts to develop a biomarker that may identify which PDAC patients would be most appropriately treated with CM24. For NT219, we are about to complete the enrollment of patients in both dose-escalation study arms, monotherapy, and in combination with cetuximab, and plan to announce the top-line results at one of the upcoming medical conferences."
"Purple's team and I look forward to continuing to execute on our plans and pursuing our mission to bring hope and to transform the lives of many cancer patients in need."
Corporate Updates
- Immunorizon Acquisition Expands Company Pipeline
Purple Biotech expanded its product pipeline through the acquisition of Immunorizon Ltd. This acquisition brings a portfolio of potential multi-specific T and NK cell engager oncology therapies that selectively activate the immune response within the tumor microenvironment (TME). The lead asset targets the antigen 5T4, activating both T and NK cells to mount a powerful immune system response against cancer cells; importantly, the compound includes a cleavable capping technology that confines the compound’s therapeutic activity to the local TME, thereby potentially increasing the anticipated therapeutic index in patients. The acquisition provides Purple Biotech with a technology platform for tri-specific antibody compounds and offers the potential to further expand to additional targets. The Company anticipates initiating clinical trials evaluating the first of these assets in 2025.
- First Patient Dosed in Open Label, Randomized Arm of CM24 Phase 2 Clinical Trial
Purple Biotech announced on February 14, 2023, that the first patient had been dosed in the randomized arm of the open label Phase 2 clinical trial evaluating CM24 in the treatment of advanced metastatic pancreatic adenocarcinoma (PDAC).
The ongoing Phase 2 trial is investigating CM24, a novel, first-in-class monoclonal antibody that targets CEACAM1, an immune checkpoint protein that promotes tumor immune evasion. The study design compares, in a randomized fashion, treatment with CM24 combined with the PD-1 immune checkpoint inhibitor nivolumab and standard-of-care (SoC) chemotherapy vs. SoC chemotherapy in second-line PDAC patients. Purple Biotech has now treated the first patient in this randomized Phase 2 study that is designed to include approximately 30 patients in the experimental cohort and an additional approximately 30 patients in the control cohort. The Company has completed the enrollment of patients in the safety run-in arms, during which no dose-limiting toxicities (DLTs) have been observed to date and dosed the first patients in the study’s randomized arms. The primary endpoint of this randomized part of the trial is overall survival. We expect to share initial data from this study by the end of 2023 and a topline report by the end of 2024.
- Biomarker Data from CM24 Phase 1 Dose Escalation Study
On March 16, 2023, Purple Biotech shared new results from exploratory analyses from a Phase 1 dose escalation study that assessed the safety and tolerability of CM24 plus nivolumab (NCT04731467). The study enrolled 14 patients with advanced cancers, including 11 patients with PDAC, two with colorectal adenocarcinoma (CRC) and one with papillary thyroid cancer. The analyses conducted in eight evaluable PDAC patients demonstrate clinically meaningful and durable reductions in serum myeloperoxidase, a biomarker for neutrophil extracellular traps (NETs), which promote immune evasion, tumor progression and metastases. These reductions in NET biomarkers followed treatment with CM24 plus nivolumab, both immediately and 15 days after the first administration. In addition, analyses of tumor samples derived from the evaluable PDAC patients suggest that patient survival may be positively associated with higher levels of CEACAM1+ tumor-infiltrating lymphocytes in the TME. These results, along with additional data from this clinical study, are part of the Company’s effort aimed at identifying and evaluating the potential utility of a biomarker to optimize future patient selection.
- New Preclinical Data on Potential of NT219 to Re-sensitize Resistant Tumors to Immune Checkpoint Inhibitors
On April 19, 2023, Purple Biotech announced research findings at the American Association for Cancer Research (AACR) Annual Meeting 2023 in Orlando. The study, conducted by researchers at The University of Texas MD Anderson Cancer Center, showcased the potential of Purple Biotech's NT219, a novel small molecule dual inhibitor, to enhance the effectiveness of Immune Checkpoint Blockage (ICB) therapies. Results demonstrated that NT219, in combination with anti-PD1 or anti-CTLA4 drugs, effectively reprogrammed the immune profile within the TME, converting resistant tumors into responders. In vivo studies using immunocompetent mice demonstrated that the combination of NT219 with either anti-PD1 or anti-CTLA4 therapies significantly increased the presence of activated CD8 cytotoxic T cells and NK cells in the TME, while reducing immunosuppressive populations. Furthermore, the synergistic effect of NT219 and anti-PD1 therapy resulted in significant tumor growth inhibition of ICB-resistant tumors. The study also revealed that NT219 effectively diminished the activation of IRS1 and STAT3, two proteins associated with drug resistance, in both ICB-resistant and ICB-sensitive melanoma cells. These findings may provide a promising avenue for improving the efficacy of ICB therapies in treating resistant tumors.
- Debuts Scientific Advisory Board
Purple Biotech announced on April 25, 2023, the inauguration of its Scientific Advisory Board (SAB). Purple Biotech anticipates conducting regular SAB meetings to advise and assist management with significant scientific judgements regarding its clinical trials as well as to perform external scientific review of pre-clinical and R&D activities.

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/.
