About Chemomab Therapeutics Ltd. Chemomab is a clinical stage biotechnology company developing innovative therapeutics for immune-fibrotic diseases with high unmet need. Based on the unique role of the soluble protein CCL24 in promoting fibrosis and inflammation, Chemomab developed nebokitug, a first-in-class dual activity monoclonal antibody that neutralizes CCL24 and has demonstrated disease-modifying potential. In clinical and preclinical studies, nebokitug has been shown to have a favorable safety profile and has been generally well-tolerated, with the potential to treat multiple severe and life-threatening immune-fibrotic diseases. Chemomab has reported positive results from five clinical trials of nebokitug, including the Phase 2 SPRING trial in patients with primary sclerosing cholangitis.
