Figitumumab (previously CP-751871) is a monoclonal antibody[1] targeting the insulin-like growth factor-1 receptor that was investigated for the treatment of various types of cancer, for example adrenocortical carcinoma[2] and non-small cell lung cancer (NSCLC).[3]

This drug was being developed by Pfizer, but they ceased development of the drug in January 2011 and has stopped its manufacture.[4]

Anti-cancer mechanism

See Insulin-like growth factor 1 receptor role in cancer.

Clinical trials

The first phase III trial (for NSCLC) was suspended in December 2009 due to excess deaths[5] but others continued.[6][7]

It was to have been included in the I-SPY2 breast cancer trial.[8]
