What is "matuzumab"

n. A humanized monoclonal antibody used to treat cancer.

Matuzumab (formerly EMD 72000) is a humanized monoclonal antibody for the treatment of cancer. It binds to the epidermal growth factor receptor (EGFR) with high affinity. The mouse monoclonal antibody (mAb425) from which matuzumab was derived was developed at the Wistar Institute in Philadelphia, Pennsylvania

Produced and developed by Merck Serono in cooperation with Takeda Pharmaceutical, it has undergone phase II clinical trials for the treatment of colorectal, lung, esophageal and stomach cancer early in the 2000s. In August 2007, Merck Serono announced that the preliminary results of the colorectal cancer study were less than promising, and that further trials for treating this type of cancer may be abandoned. In February 2008, the development was halted because of disappointing study results.
