CMAB and Kintor Announce a New Comprehensive Collaboration to Develop and Manufacture the ALK-1 Monoclonal Antibody
  • 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.
