Patients with androgen independent prostate cancer who do not have bone or visceral metastases are selected for this trial because they are a patient population that is likely to have no symptoms from the disease or rapid progression that would suggest the need for chemotherapy. Additionally, given the preclinical data suggesting that IGF-1 expression and signaling occurs concomitantly with the onset of androgen independent growth, it is felt that testing in the "early" androgen independent state is warranted. This trial is consistent with overall goal to develop IGF-1 targeted therapies in patients with disease progression and a lower disease burden.
