  • This agreement represents the first strategic cooperation between two of the key players in biopharmaceutical industries in Suzhou, China.


  • ALK-1(Activin receptor-like kinase-1) antibody was originally developed by Pfizer. Pfizer completed two Phase I clinical trials in more than 100 patients with advanced solid tumors in the United States, Italy, South Korea, and Japan.


  • Kintor has been granted an exclusive and worldwide rights to develop, manufacture and commercialize this novel anti-angiogenic antibody drug, which is expected tobecome the first fully human therapeutic monoclonal antibody that targets ALK-1 globally.


SUZHOU, China, August 22, 2019 - CMAB Biopharma (Suzhou) Inc. (“CMAB”), a pure-play CDMO business in biologics and Suzhou Kintor Pharmaceuticals, Inc. (“Kintor”), an innovative biopharmaceutical enterprise, announced a comprehensive strategic cooperation agreement for the development and manufacturing of ALK-1 monoclonal antibody (mAb).

ALK-1 mAb, a monoclonal antibody targeting ALK-1 had been studied in two Phase-I clinical trials in the United States, Italy, South Korea and Japan from 2007 to 2014. In these two clinical studies, ALK-1 mAb demonstrated favorable PK and safety profile and reasonable clinical benefits, which suggest that this novel therapeutic antibody has a potential to be a first-in-classin targeting ALK-1, an angiogenesis target. Kintor has been granted the exclusiveand worldwide rights to develop, manufacture and commercialize this novel anti-angiogenic drug, and has initiated a Phase II clinical trial in the combination with Nivolumab in the patients with hepatocellular carcinoma (HCC) in Taiwan. This is the first time Pfizer has licensed a Chinese company to develop a new antibody drug for oncology indications, which is expected to become the first fully human therapeutic monoclonal antibody that targets ALK-1 in the world.

According to the agreement, CMAB will provide a full range of CMC research and manufacturing services that meet the IND application requirements of China and the United States. This strategic cooperation will support the clinical development of ALK-1 antibody worldwide by Kintor.

To support Kintor's clinical development plan, CMAB will not only provide professional CMC technology and manufacturing services for Kintor, but also make full use of its team's expertise in IND application both in China and the United States. CMAB is also excited for supporting the commercialization and marketing of ALK-1 antibody in the future.
