TEL AVIV, Israel, June 28, 2022 /PRNewswire/ -- Chemomab Therapeutics, Ltd. (Nasdaq: CMMB) (Chemomab), a clinical stage biotechnology company focused on the discovery and development of innovative therapeutics for fibrotic and inflammatory diseases with high unmet need, today reported that the United States Patent and Trademark Office has issued a new patent for CM-101, Chemomab's first-in-class monoclonal antibody that neutralizes CCL24, a novel disease target at the confluence of fibrosis and inflammation. The new patent covers the use of CM-101 and sequence-related CCL24 antibodies for the treatment of hepatic (liver) diseases. CM-101 is currently in a Phase 2 trial for the treatment of primary sclerosing cholangitis (PSC), a potentially lethal disease affecting the bile ducts of the liver, as well as a Phase 2 liver fibrosis study.

"We have been diligent in obtaining expanded intellectual property coverage for CM-101 and sequence-related CCL24 neutralizing antibodies," noted Adi Mor, PhD, co-founder and Chief Scientific Officer of Chemomab. "This new U.S. patent covering the use of CM-101 in treating liver diseases provides major additional protections for our current clinical programs in PSC and liver fibrosis, as well as other serious liver disorders we may pursue going forward."

U.S. Patent No.11365246, "Anti CCL24 (eotaxin 2) Antibodies for Use in the Treatment of Hepatic Disease" has a filing date of March 8, 2018, and a grant date of June 21, 2022, with corresponding first to expire claims in 2038 and a possible patent term extension of up to an additional five years, as provided under the Drug Price Competition and Patent Restoration Act (35 U.S.C. §156).

About CM-101

CM-101 is a monoclonal antibody that neutralizes the soluble protein CCL24, a cytokine family member that can trigger self-reinforcing inflammatory and fibrotic pathways implicated in a number of serious progressive diseases. In extensive preclinical studies, Chemomab has validated CCL24's role as a target while establishing CM-101 proof-of-concept in studies in multiple disease models and patient samples. CM-101 was safe and well tolerated in Phase 1 clinical trials and it improved liver biomarkers, decreased liver stiffness and demonstrated a favorable PK and target engagement profile in patients with nonalcoholic fatty liver disease. CM-101 is currently in two Phase 2 trials in patients with primary sclerosing cholangitis and liver fibrosis. A third Phase 2 trial in systemic sclerosis is expected to start before year-end.
