Sichuan Kelun-Biotech Biopharmaceutical Co., Ltd. has announced the receipt of an upfront payment in cash and equity under a license agreement with Windward Bio AG for the co-development project SKB378/HBM9378/WIN378. This project involves a novel, recombinant fully human monoclonal antibody designed to potently bind to the TSLP ligand and inhibit the TSLP mediated signaling pathway, relevant in treating conditions such as asthma and chronic obstructive pulmonary disease (COPD). The company recently received regulatory approval for an IND application for SKB378/HBM9378/WIN378 in January 2025 for the treatment of COPD from the National Medical Products Administration in China. A phase 1 clinical trial for moderate-to-severe asthma has been completed, and Windward Bio is preparing for a phase 2 trial. However, the company has cautioned shareholders and potential investors that SKB378/HBM9378/WIN378 may not ultimately be successfully developed and commercialized.
