Many of the posts that I have written discussed the need for evaluating our current advanced prostate cancer drugs in both combinations and their sequencing. We have a number of new drugs, but we don’t understand how best to sequence them, or whether or not some drugs would do better and extend life by taking [...]
The pharmaceutical company Exelixis has announced that their experimental treatment, cabozantinib has failed the Phase III clinical trial for men with metastatic castration-resistant prostate cancer (mCRPC). In the trial the experimental treatment cabozantinib was compared to the drug prednisone. In the trial known as COMET-1, Cabozantinib, a tyrosine kinase inhibitor, did not meet its primary [...]
Osteoblasts and osteoclasts are the process that the body uses to breakdown old bone and then to rebuild it with new bone. c-Met is a tyrosine kinase expressed by osteoblasts and osteoclasts, and overexpressed by prostate cancer cells. This over expression leads to the eventual development of bone metastases. The experimental treatment known as Cabozantinib [...]
Cabozantinib (XL184) is an orally bioavailable tyrosine kinase inhibitor with activity against MET and vascular endothelial growth factor receptor 2. It is designed to target the men with castration resistant prostate cancer (CRPC). Results from a phase II randomized discontinuation trial with an expansion cohort of XL184 have recently been released. The trial included men [...]
According to researchers from the University of Michigan Comprehensive Cancer Center, Ann Arbor, Michigan men with advanced prostate cancer experienced significant and rapid positive effects from an investigational treatment known as cabozantinib. In a n article published online in the Journal of Clinical Oncology (Nov. 19, 2012) approximately two-thirds of men who were treated with [...]
