Sichuan Kelun-Biotech Biopharmaceutical Co., Ltd. ("Kelun-Biotech" or the "Company", 6990.HK) announced that it has received a clinical trial notice from the Center for Drug Evaluation (CDE) of the National Medical Products Administration (NMPA) approving the Investigational New Drug (IND) application for PD-1 x VEGF bispecific antibody SKB118 (also known as CR-001) for the treatment of advanced solid tumors.

In December 2025, Kelun-Biotech and Crescent Biopharma ("Crescent") entered into a strategic collaboration for SKB118/CR-001. Under the collaboration, Crescent granted Kelun-Biotech exclusive rights to research, develop, manufacture and commercialize SKB118/CR-001 in Greater China (including Mainland China, Hong Kong, Macau, and Taiwan). In January 2026, Crescent announced the regulatory clearance of the IND application for SKB118/CR-001 by the U.S. Food and Drug Administration (FDA) to initiate its global ASCEND Phase I/II clinical trial (NCT07335497) for the treatment of locally advanced or metastatic solid tumors. The trial is ongoing and expected to initially enroll up to 290 patients.

Dr. Michael Ge, CEO of Kelun-Biotech, stated: "We are pleased to see the approval of the IND application for SKB118 in China, which marks the simultaneous advancement of clinical development in China and globally. Since entering into the collaboration with Crescent, we have worked closely and leveraged complementary advantages with each other to efficiently drive the R&D of the collaborative product candidates. Based on our ADC+IO strategies, we will actively explore the potential of combining SKB118 with our proprietary ADC assets to unlock the synergistic value of our portfolio and expand more treatment possibilities for cancer patients."
