BTG Licensee Cougar Biotechnology Initiates Phase I/II Trial of CB7630 in Advanced Breast Cancer
News Nov 21, 2008
Cougar Biotechnology, Inc. has announced that the first patient was enrolled in a Phase I/II clinical trial of the Company's drug candidate CB7630 (abiraterone acetate), an orally active inhibitor of the steroidal enzyme 17alpha-hydroxylase/C17, 20 lyase, for the treatment of advanced breast cancer.
The Phase I/II trial is being conducted at The Institute of Cancer Research in London and managed by the Drug Development Office of Cancer Research UK, which is funding the trial.
The Phase I/II clinical trial, which is open only to UK women, is an open label, dose escalating study to evaluate the safety and efficacy of CB7630 administered daily to patients with estrogen receptor (ER) positive or androgen receptor (AR) positive, metastatic breast cancer.
Patients enrolled in the trial have disease that has progressed after at least two lines of hormonal therapies, such as aromatase inhibitors and tamoxifen.
Alan H. Auerbach, Chief Executive Officer and President of Cougar Biotechnology said, "Initiating the Phase I/II clinical trial of CB7630 in breast cancer patients is an important milestone for the Company and for the clinical development of the drug, as it represents a second potential indication for CB7630."
Lipid droplets have been found to play critical roles in the life cycles of certain proteins involved in gene expression. Now, a new study describes how lipid droplets regulate these proteins. The research has implications for understanding what helps embryos survive and could cause us to reconsider how we look at lipid-related diseases like obesity.READ MORE
