Motesanib (AMG 706) is an experimental drug candidate originally developed by Amgen[1] but later investigated by the Takeda Pharmaceutical Company. It is an orally administered small molecule belonging to angiokinase inhibitor class which acts as an antagonist of VEGF receptors, platelet-derived growth factor receptors, and stem cell factor receptors.[2] It is used as the phosphate salt motesanib diphosphate. After clinical trials in thyroid cancer, non-small cell lung cancer, gastrointestinal stromal cancer, colorectal cancer, and breast cancer, the drug was not found to show sufficient efficacy for further development, and development was abandoned by Takeda.[3]

Clinical trials[edit]

Motesanib was originally investigated for effectiveness against advanced nonsquamous non-small-cell lung cancer (NSCLC), with Phase II trials indicating an effectiveness comparable to bevacizumab when they were both used in combination with paclitaxel/carboplatin.[4] However a later and more detailed Phase III trial failed to show any benefit for the treatment of NSCLC.[2][5] A second Phase III trial was started in 2012,[6] which focused on patients from Asian backgrounds (performed on the bases of subgroup analysis)[7] however this also failed to meet its primary endpoint.[8]

The drug has undergone a Phase II evaluation as first-line therapy for breast cancer[2] however this study found no evidence to support further investigation.[9] Phase II testing against persistent or recurrent ovarian, fallopian tube and primary peritoneal carcinomas was also unsuccessful.[10] Two phase II clinical trials for thyroid cancer showed promising results.[11][12][13]
