Data Further Support Potential of NT219 to Overcome Cancer Drug ResistanceTEL AVIV, Israel, Oct. 16, 2020 (GLOBE NEWSWIRE) — Kitov Pharma Ltd. (“Kitov”) (NASDAQ/TASE: KTOV), a clinical-stage company advancing first-in-class therapies to overcome tumor immune evasion and drug resistance, announced new data supporting the mechanism of action of NT219, a dual inhibitor, novel small molecule targeting IRS1/2 and STAT3 is being presented in a video recorded presentation at the Epigenetics and Metabolism AACR Special Virtual Conference by researchers at Tel-Aviv University. The data was generated as part of the Company’s collaboration with Professor Ido Wolf, Head of the Oncology Division, Tel Aviv Sourasky Medical Center.The new data demonstrates IRS2-amplified colorectal cancer (CRC) cells upregulate β-catenin expression, and treatment with NT219 significantly decreased the β-catenin transcriptional activity in these cells. In addition, NT219 markedly inhibited cell viability in a dose-dependent manner. Moreover, there was a unique role for IRS2 in promoting brain metastasis of CRC, suggesting AKT and β-catenin pathways downstream of IRS2 may be involved in mediating the enhanced aggressive phenotype of IRS2-amplified CRC cells in the brain microenvironment. β-catenin signaling by Wnt has been shown to have a number of different cellular influences. Besides cellular proliferation via protein stabilization to promote cellular growth, Wnt/ β-catenin has demonstrated a role in the establishment of the blood brain barrier and impacts the tumor microenvironment, associated with the therapeutic resistance of cancer cells (Dzobo et al, 2019). “These new mechanism of action data, together with the compelling results from our preclinical studies of NT219, further support the rationale behind combining NT219 with various targeted and immune oncology approaches, both in peripheral and nervous system tumor tissues,” said Bertrand Liang, M.D., Ph.D., Chief Medical Officer of Kitov. “We are currently enrolling patients in our Phase 1/2 clinical trial of NT219 as monotherapy for the treatment of advanced solid tumors, as well as in combination with cetuximab, an epithelial growth factor receptor (EGFR) blocking monoclonal antibody, for the treatment of recurrent and/or metastatic solid tumors and head and neck cancer or colorectal adenocarcinoma. We expect top-line data from the first part of this important study in the second half of 2021.”Previously completed preclinical studies demonstrated NT219’s ability to overcome cancer drug resistance in patient-derived xenograft (PDX) models of various advanced cancer types, and to revert resistance to pembrolizumab (Keytruda®). Mice treated concomitantly with a combination of pembrolizumab and NT219 demonstrated complete blockage of tumor progression. Similarly, the combination of NT219 with cetuximab sensitized resistant tumors to this therapy.About Kitov Pharma
Kitov Pharma Ltd. (“Kitov”; NASDAQ/TASE: KTOV) is a clinical-stage company focusing on advancing first-in-class therapies to overcome tumor immune evasion and drug resistance, to create successful long-lasting treatments for people with cancer. Kitov’s oncology pipeline includes NT219 and CM24. NT219 is a small molecule targeting the novel cancer drug resistance pathways IRS1/2 and STAT3. Kitov is currently advancing NT219 as a monotherapy treatment of advanced solid tumors and in combination with cetuximab for the treatment of recurrent or metastatic squamous cell carcinoma of head and neck cancer (SCCHN) in a phase 1/2 study. CM24 is a monoclonal antibody blocking CEACAM1, a novel immune checkpoint that supports tumor immune evasion and survival through multiple pathways. Kitov plans to advance CM24 as a combination therapy with anti-PD1 checkpoint inhibitors in selected cancer indications in a phase 1 study followed by a phase 2 for the treatment of non-small cell lung cancer NSCLC and pancreatic cancer. Kitov has entered into a clinical collaboration agreement with Bristol Myers Squibb Company for the planned phase 1/2 clinical trials to evaluate the combination of CM24 with the PD-1 inhibitor nivolumab (Opdivo®). Kitov is also the owner of Consensi®, a fixed-dose combination of celecoxib and amlodipine besylate, for the simultaneous treatment of osteoarthritis pain and hypertension that was approved by the FDA for marketing in the U.S. Consensi® is being sold in the U.S. by Burke Therapeutics, the marketing partner of Kitov’s U.S. distributor, Coeptis Pharmaceuticals. Kitov has also partnered to commercialize Consensi in China and South Korea. The company is headquartered in Tel Aviv, Israel.
