Endothelin-1 (ET-1) is implicated in the development of the
osteoblastic bone lesions that characterize metastatic
disease.

Thalidomide is a putative angiogenesis inhibitor. It inhibits
angiogenesis and reduces VEGF levels
Bevacizumab, a humanized monoclonal antibody that targets
VEGF
The National Cancer Institute is currently conducting a phase II
study of a four-drug combination consisting of docetaxel,
prednisone, thalidomide, and bevacizumab in men with
chemotherapy-naive progressive HRPC, and the CALGB is
coordinating a phase III, double-blinded, placebo-controlled trial of
docetaxel plus prednisone with or without bevacizumab

conclusions
In the clinic, chemotherapy and bisphosphonates are not
given in any particular sequence, and tratment intervals
vary; preclinical data indicate that to achieve maximum
effects from the combination of treatments, the sequence
and the timing of drug administration have an important role
and could determine the efficacy of the therapy, both in
advanced disease and in the adjuvant setting.
