About
Adnexus Therapeutics, founded in 2003 and headquartered in Waltham, Massachusetts, was a biopharmaceutical company that pioneered Adnectin therapeutics — engineered variants of the tenth type III domain of human fibronectin. Adnectins were designed as a new protein scaffold platform to generate highly potent, specific, and stable therapeutic agents with favorable half-life and high-yield E. coli production. The company's lead oncology compound, CT-322, was an Adnectin inhibitor of vascular endothelial growth factor receptor-2 (VEGFR-2) developed as an anti-angiogenic cancer therapy. Adnexus was founded by Flagship Pioneering (then Flagship Ventures) and acquired by Bristol-Myers Squibb in September 2007 for approximately $430 million, making it one of the largest biotech acquisitions of that year.
