Chemomab Announces FDA Clearance of Its IND Application for CM-101, a First-In-Class CCL24 Neutralizing Antibody for the Treatment of Primary Sclerosing Cholangitis

    • First U.S. IND Enables Increase in the Number of Clinical Sites for Chemomab’s Ongoing Phase 2 SPRING Trial
    • Initiation of U.S. Trials in Line with Announced Corporate Strategy to Expand the Company’s Clinical and Commercial Presence in the U.S.

TEL AVIV, Israel – Chemomab Therapeutics, Ltd. (Nasdaq: CMMB) (Chemomab), a clinical-stage biotech company focused on the discovery and development of innovative therapeutics for fibrotic and inflammatory diseases with high unmet need, today announced that the U.S. Food and Drug Administration (“FDA”) has cleared the company’s Investigational New Drug (“IND”) application for CM-101, a first-in-class CCL24-neutralizing antibody for the treatment of the rare disease primary sclerosing cholangitis (PSC). The Phase 2 SPRING trial assessing CM-101 as a potential treatment for PSC is already underway in Europe and Israel and is now being expanded to include U.S. sites.

“FDA clearance of the IND for our first U.S. clinical trial is an important milestone for Chemomab,” said Adi Mor, PhD, co-founder and Chief Scientific Officer of Chemomab. “This clearance allows us to significantly increase the number of clinical sites in our Phase 2 SPRING study, as we augment our development capabilities and expand our clinical and business presence in the U.S.”

Chemomab’s SPRING trial is a Phase 2 multicenter, double-blind, placebo-controlled study designed to evaluate the safety and efficacy of CM-101 over 15 weeks of treatment in patients with PSC. The trial will include clinical sites in the U.S., U.K., E.U. and Israel. The initial clinical readout is expected in 2022.

About CM-101

Chemomab’s lead clinical candidate, CM-101, is a first-in-class monoclonal antibody targeting the soluble protein CCL24, a novel and differentiated target that is overexpressed in fibrotic tissues. In preclinical studies, CCL24 has been shown to play a unique and pivotal role in promoting fibrosis and inflammation, inducing a dual effect that includes the direct activation of fibroblasts and recruitment of inflammatory cells to damaged tissues. CM-101 has been shown to substantially attenuate fibrosis and inflammation across a wide range of in vitro and in vivo models, including experimental models of primary sclerosing cholangitis, systemic sclerosis, idiopathic pulmonary fibrosis, and nonalcoholic steatohepatitis.

CM-101 appeared safe and well-tolerated in Phase 1a and 1b clinical studies in healthy volunteers and non-alcoholic fatty liver disease (NAFLD) patients. It is currently being assessed in the Phase 2 SPRING trial in PSC and in a Phase 2 liver fibrosis study. A third Phase 2 trial in systemic sclerosis is expected to begin in early 2022.

About Primary Sclerosing Cholangitis

Primary sclerosing cholangitis is a rare and serious disease of the bile ducts in the liver. An estimated 30,000 people in the U.S. alone have the condition. In PSC, inflammation eventually leads to fibrosis, or scarring, of the bile ducts and the liver. These scars make the ducts hard and narrow and gradually cause serious liver damage. The majority of people with PSC also have inflammatory bowel disease. The exact cause of PSC is unknown, but an autoimmune-fibrotic mechanism may play an important role. PSC typically progresses slowly but it can eventually lead to repeated infections, liver failure and cancers of the bile duct, liver or colon. There are no approved therapies for PSC—care focuses on managing symptoms and, when possible, temporarily opening blocked bile ducts. A liver transplant is the only known intervention with curative potential for advanced PSC, but the disease may recur in the transplanted liver in some patients.

About Chemomab Therapeutics Ltd.

Chemomab is a clinical-stage biotech company focusing on the discovery and development of innovative therapeutics for fibrotic and inflammatory diseases with high unmet need. Based on the unique and pivotal role of the soluble protein CCL24 in promoting fibrosis and inflammation, Chemomab developed CM-101, a monoclonal antibody designed to bind and block CCL24 activity. CM-101 has demonstrated the potential to treat multiple severe and life-threatening fibrotic and inflammatory diseases. It is currently in two Phase 2 safety and efficacy trials—one in patients with primary sclerosing cholangitis and the second in patients with liver fibrosis, with a third Phase 2 trial in systemic sclerosis expected to begin early in 2022.
