Chemomab Awarded New European Patent for CM-101, Its First-in Class Monoclonal Antibody in Phase 2 Clinical Development for Primary Sclerosing Cholangitis

—European Patent Office Grants New Patent Covering Use of CM-101 for the Treatment of Multiple Liver Diseases including Primary Sclerosing Cholangitis—

—Further Extends Protections Afforded by CM-101 Composition of Matter and Methods and Use Patents That Have Issued in the U.S., Europe, Israel and Related Territories—

TEL AVIV, Israel, March 25, 2024 (GLOBE NEWSWIRE) -- Chemomab Therapeutics Ltd. (Nasdaq: CMMB), (Chemomab), a clinical stage biotechnology company developing innovative therapeutics to treat rare fibro-inflammatory diseases with high unmet need, today reported that the European Patent Office has granted a new patent for CM-101, Chemomab’s first-in-class monoclonal antibody that neutralizes CCL24, a novel disease target that has been shown to play a critical role in the processes that drive fibrosis and inflammation. CM-101 is currently being assessed in the global Phase 2 SPRING trial for the treatment of primary sclerosing cholangitis (PSC). Patient enrollment in the trial has been completed, with a topline data readout expected midyear 2024.

The new European patent covers the use of CM-101 and sequence-related anti-CCL24 antibodies for the treatment of hepatic (liver) diseases, including PSC.

PSC is a potentially lethal condition that lacks any FDA-approved therapies and frequently requires liver transplantation. Unlike other drugs in development for PSC, CM-101 has a unique dual mechanism of action that simultaneously blocks fibrosis and inflammation. In clinical and preclinical studies, this distinctive approach has been shown to inhibit fibrogenesis and interfere with core PSC pathways.

“This new patent covering the use of CM-101 in liver diseases provides additional intellectual property protection in key European markets in addition to the CM-101 composition of matter patent that has already been granted in Europe. It further supplements the extensive protections afforded by the multiple patents issued and allowed in the U.S., Israel, China and other major territories,” said Adi Mor, PhD, co-founder, Chief Executive Officer and Chief Scientific Officer of Chemomab. “This is an important time for Chemomab as we prepare for the midyear release of topline data from our Phase 2 PSC trial, which could provide the first substantial clinical proof-of-concept of CM-101’s therapeutic activity and represents a potential major catalyst for the company.”
