A
GM-CSF given in combination with ketoconazole and mitoxantrone in patients with progressive prostate cancer despite androgen deprivation and prior taxane containing chemotherapy
|
Drug: GM-CSF
GM-CSF will be administered as a subcutaneous injection at a dose of 250mcg/m2/d (maximum 500 mcg) on weeks 2 and 3 each 21 day cycle (total of 14 days).
Drug: Ketoconazole
Ketoconazole will be administered daily at a dose of 400 mg po tid (either 1 hour before or 2 hours after meals), ascorbic acid 250 mg po tid (given with ketoconazole) and replacement doses of hydrocortisone (20 mg po in the morning and 10 mg po in the evening).
Drug: Mitoxantrone
Mitoxantrone will be given at dose of 12 mg/m2 every 3 weeks, up to a maximum cumulative dose of 140 mg/m2

Prostate cancer is the second leading cause of cancer death in American men. Hormonal ablation, in the form of medical or surgical castration is the cornerstone of management for metastatic prostate cancer however, treatment options for a patient in whom androgen ablation fails are limited. Second-line hormonal agents are generally associated with low response rates and no documented survival benefit.
A variety of taxane-based regimens have been tested in hormone refractory prostate cancer, yielding response rates between 38% - 69%. As responses to taxane-based regimens have appeared to exceed those typically associated with mitoxantrone plus prednisone, taxane-based therapy has been widely used in the community, typically as first line therapy. Second line therapy, which are non-taxane based and have comparable activities do not exist.
This study builds on experience in drug development for advanced prostate cancer demonstrating the following:
The importance of this trial in the broader context of clinical research for prostate cancer is twofold: One, it represents an attempt to offer second line immunotherapy plus chemotherapy to patients who have failed prior frontline taxane based therapy. Two, this is the first trial to assess the combination of GM-CSF plus ketoconazole and mitoxantrone.
