CM24 Phase 2 Pancreatic Cancer Interim Data Selected for Late Breaking Abstract Poster Presentation at ASCO 2024 – Interim results to be Announced June 1, 2024

REHOVOT, Israel, May 21, 2024 (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 three months ended March 31, 2024.

“We look forward to presenting compelling interim Phase 2 CM24 data for the treatment of pancreatic cancer at ASCO 2024, where we were selected for a Late Breaking Abstract presentation. These data suggest an exciting medical direction, demonstrating potentially reduced risk of disease progression and death in a very difficult to treat indication. Following the announcement of interim results at ASCO on June 1, 2024, we expect to present topline data before the end of year; these clinical milestones will potentially mark significant catalysts for the value of our development pipeline,” stated Gil Efron, Chief Executive Officer of Purple Biotech. “We also continue to make solid progress on NT219, which is headed into a Phase 2 trial in head and neck cancer, as well as on our tri-specific antibody platform following a Pre-IND meeting with the FDA that provided a clear path forward for our development plan through Phase 1.”

Q1 2024 and Recent Clinical & Corporate Highlights:

• CM24 Pancreatic Cancer Study Selected for Late Breaking Abstract Poster Presentationat ASCO 2024
• Interim data suggest reduced risk of progression or death in the CM24/nivolumab plus standard of care Nal-IRI/5FU/LV arm of the study supported by higher overall response rate (ORR) and disease control rate (DCR) anddecreasing CA19-9 in the experimental arm. Full interim data have been submitted to the ASCO Meeting.
• Interim datato be announced on June 1, 2024 in conjunction with the ASCO presentation
• Topline data expected Q42024

The American Society of Clinical Oncology (ASCO) selected Purple Biotech’s poster titled “Interim results of the Randomized Phase 2 Cohort of Study FW-2020-01 Assessing the Efficacy, Safety and Pharmacodynamics of CM24 in combination with Nivolumab and Chemotherapy in Advanced/metastatic Pancreatic Cancer” for a Late Breaking presentation at ASCO’s 2024 Annual Meeting.

The Phase 2 study is evaluating CM24 in combination with Bristol Myers Squibb’s PD-1 inhibitor nivolumab plus standard of care (SoC) chemotherapy in second line pancreatic ductal adenocarcinoma (PDAC) patients compared to SoC chemotherapy alone. The experimental arms of the study dosed patients with CM24 plus nivolumab and one of two SoC chemotherapies, gemcitabine/nab-paclitaxel or Nal-IRI/5FU/LV, while the control arms dosed with either respective chemotherapy alone. Approximately 60 patients have been enrolled in the randomized study across 18 centers in the U.S., Spain and Israel. Data from the gemcitabine/nab-paclitaxel arm is not yet mature for analysis.

• Phase 2 study of NT219in combination with cetuximab as a 2nd Line treatment for R/M SCCHNis planned to commence in 2024.
• NT219Positive Efficacy Data in Head & Neck Cancer Presented at ESMO-TAT 2024.
• Posters presented at AACR 2024 demonstrated NT219’s efficacy in suppressing cancer stem cells, overcoming resistance to KRASinhibitors andpotential biomarkers for NT219 therapy.
• Established Head & Neck Cancer Scientific Advisory Board.

In a presentation at ESMO-TAT 2024, NT219 in combination with cetuximab demonstrated safety and early activity in patients with Recurrent/Metastatic Squamous Cell Carcinoma of the Head and Neck (R/M SCCHN) with dose-proportional PK values. Of the 7 evaluable R/M SCCHN patients treated at the maximum doses of 50 and 100mg/kg in which anti-tumor activity was observed, the tumor objective response rate (ORR) was 29% and the disease control rate (DCR) was 71%, both highly encouraging results. 100mg/kg was determined to be the recommended Phase 2 dose for NT219 in combination with cetuximab in the treatment of R/M SCCHN.

Key findings were shared in two poster presentations at the American Association for Cancer Research (AACR) 2024 annual meeting in San Diego, California. NT219 was found to significantly suppress cancer stem cells, suggesting a novel therapy and new mechanism to combat cancer recurrence and overcoming resistance to KRAS(G12C) and KRAS(G12D) inhibitors in NSCLC and PDAC cells, respectively. NT219 reverses acquired resistance to KRAS inhibitors by addressing both cellular escape pathways and cancer stem cell mechanisms. Potential biomarkers for NT219 therapy were presented in an additional poster at AACR 2024, and on-target effects of the therapy were demonstrated in patients’ tumors. Analysis of patients’ biopsies pre-treatment suggests activated IGF1R and STAT3 as potential biomarkers for this therapy.

In preparation for its upcoming Phase 2 trial of NT219, Purple Biotech convened a Scientific Advisory Board (SAB) specifically focused on the R/M SCCHN indication. The SAB is comprised of head and neck cancer key opinion leaders including oncologists, researchers, and investigators. The SAB has provided valuable guidance on clinical studies for NT219 in combination with cetuximab as a second/third line treatment and potentially in combination with a PD1 inhibitor as a first line treatment.

• Proof of Concept Achieved forTri-Specific Antibody Platform Technology
  • Platform has potential to produce a pipeline of promising drug candidates across numerous solid cancer tumors
  • Lead asset, IM1240, expected to be ready for Phase 1study by early 2026
    

Purple Biotech’s tri-specific platform is a T cell engager via the anti-CD3 arm, and an NK cell engager via the anti-NKG2A arm, which also functions as an important immune checkpoint inhibitor of both NK cells and specific subsets of T cells; this tri-specific approach unleashes both innate and adaptive immune systems against the tumor. Preclinical studies demonstrated an anti-tumor response and synergistic effects of the NK cell engager with the conditionally-activated T cell engager. The tri-body platform’s cleavable capping technology confines therapeutic activity to the local tumor micro environment, which increases the anticipated therapeutic window in patients.

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. A Phase 1 dose escalation study is being concluded and a phase 2 study of NT219 at its recommended Phase 2 level in combination with cetuximab in patients with recurrent and/or metastatic SCCHN is planned. 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. Additionally, the Company is advancing a preclinical platform of a 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, which is 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/.
