“We are delighted that Dave Weiner is rejoining the company,” said Adi Mor, PhD, co-founder and Chief Executive Officer of Chemomab. “Dave has worked with Chemomab for a number of years and was a major contributor to the design of the clinical program that resulted in the successful nebokitug Phase 2 SPRING trial in primary sclerosing cholangitis (PSC). We anticipate a smooth transition with our PSC Phase 2 program now successfully completed and our planning for next steps underway. We also want to thank Matt Frankel for his contributions to our medical and clinical achievements and we wish him success in his future endeavors.”
Dr. Mor continued, “Jack Lawler has been instrumental in our clinical progress over the past three years. His leadership in building a first-rate U.S.-based clinical organization that successfully implemented a global PSC clinical program for nebokitug and delivered positive clinical results on budget and ahead of schedule has been invaluable. Jack also helped spearhead our efforts to build strong relationships with PSC opinion leaders, leading clinical centers and advocates worldwide that will serve us well going forward.”
Dr. Weiner commented, “I welcome the opportunity to rejoin Chemomab at this exciting time for the company. We have reported compelling clinical proof-of-concept data showing that nebokitug has the potential to become the first FDA-approved drug for PSC with disease-modifying activity and that it also may have potential in other fibro-inflammatory diseases. These are challenging times for our industry but with our experienced team and record of cost-effective scientific and clinical progress, I am optimistic we will realize the great medical, clinical and commercial potential of nebokitug. I look forward to working again with Jack, who I view as among the most effective clinical operations experts in our industry.”

About Chemomab Therapeutics Ltd. Chemomab is a clinical stage biotechnology company developing innovative therapeutics for fibro-inflammatory diseases with high unmet need. Based on the unique role of the soluble protein CCL24 in promoting fibrosis and inflammation, Chemomab developed nebokitug (CM-101), 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 fibro-inflammatory diseases. Chemomab has reported positive results from four clinical trials of nebokitug in patients. Based on positive data from its Phase 2 SPRING trial in primary sclerosing cholangitis (PSC), the company is preparing for potential initiation of a nebokitug PSC Phase 3 trial. The design of Phase 3 calls for a single pivotal trial based on a clinical event primary endpoint that provides a clear and streamlined pathway to potential full regulatory approval. Nebokitug has received FDA and EMA Orphan Drug and FDA Fast Track designations for the treatment of PSC. Chemomab’s nebokitug program for the treatment of systemic sclerosis has an open U.S. IND.
