TEL AVIV, Israel, Feb. 03, 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, today announced receipt from the U.S. Patent and Trademark Office (USPTO) of a Notification of Issuance for a patent application entitled, “Humanized antibodies against CEACAM1.” The patent, which expires in 2035, covers protein and DNA sequences pertaining to humanized antibodies capable of specific binding to human CEACAM1 molecules, including Kitov’s first-in-class monoclonal antibody, CM-24, pharmaceutical compositions comprising these antibodies, as well as methods for their use in treating and diagnosing cancer and other conditions.
“This recognition from the USPTO validates the unique profile of Kitov’s CM-24. The mechanism of action of CM-24 results in an enhanced cytotoxic activity of the immune system cells, inducing a tumor’s death,” commented Isaac Israel, Chief Executive Officer of Kitov. “CEACAM1 expression was found to correlate with poor prognosis in patients with non-small cell lung cancer (NSCLC). We strongly believe that the combination of CM-24 with nivolumab has the potential to result in a significant synergistic benefit in patients with NSCLC tumors expressing CEACAM1. We look forward to the initiation of our phase 1/2 clinical trial with CM-24 in the second half of 2020.”
CM-24 is a clinical-stage monoclonal antibody blocking CEACAM1, a well-validated target which is highly expressed in many solid tumors as well as on immune cells and plays a pivotal role in the immune system by blocking immune cells’ access to tumors by CEACAM1-CEACAM1 and CEACAM1-CEACAM5 interaction. CEACAM1 was also shown to regulate TIM3 which induce immune fatigue. This unique mechanism of action positions CM-24 with a differentiated inhibitor of a multi-role immune checkpoint. In a monotherapy phase 1 study, CM-24 demonstrated safety and efficacy with standard dose in about 30% of patients. Kitov will advance CM-24 as a combination therapy with anti-PD1 checkpoint inhibitors for the treatment of non-small cell lung cancer (NSCLC). Kitov has entered into a clinical collaboration agreement with Bristol Myers Squibb Company (BMY) for the planned Phase 1/2 clinical trials to evaluate the combination of CM-24 with the PD-1 inhibitor nivolumab (Opdivo®).
