A Prospective Randomized Phase III, Trial Comparing Consolidation Therapy With or Without Strontium-89 Following Induction Chemotherapy in Androgen-Independent Prostate Cancer
OBJECTIVES:
- Compare the effectiveness, in terms of overall survival, of consolidation therapy with
or without strontium chloride Sr 89 after induction chemotherapy in patients with
androgen-independent prostate cancer.
OUTLINE: This is a randomized study. Patients are stratified according to type of induction
chemotherapy (KAVE vs prednisone and docetaxel), number of bony metastases (no more than 20
vs more than 20), ECOG performance status (0-1 vs 2-3), and use of zoledronate (yes vs no).
- Induction therapy: Patients receive 1 of 2 induction therapy regimens.
- Regimen A (KAVE): Patients receive doxorubicin IV over 24 hours on day 1 and oral
ketoconazole three times daily on days 1-7 of weeks 1, 3, and 5. Patients receive
vinblastine IV over 30 minutes on day 1 and oral estramustine three times daily on
days 1-7 of weeks 2, 4, and 6. Patients receive no treatment on weeks 7 and 8.
Treatment repeats every 8 weeks for at least 2 courses* in the absence of disease
progression or unacceptable toxicity.
NOTE: *Patients continue to receive oral ketoconazole three times daily until disease
progression.
- Regimen B (prednisone and docetaxel): Patients receive oral prednisone twice daily on
days 1-21 (days 1-14 of course 5 only) and docetaxel IV over 1 hour on day 1. Treatment
repeats every 21 days for at least 5 courses in the absence of disease progression or
unacceptable toxicity.
- Consolidation therapy: Patients with a prostate-specific antigen (PSA) response
(at least 50% decline in PSA level from baseline at week 16 OR at least 2 PSA
levels decreased at least 50% from baseline) are randomized to 1 of 2
consolidation treatment arms.
- Arm I: Patients receive doxorubicin IV over 24 hours once weekly for 6 weeks plus
strontium chloride Sr 89 IV once at the beginning of chemotherapy.
- Arm II: Patients receive doxorubicin as in arm I. Patients are followed every 4 weeks
until PSA progression and then every 3 months thereafter.
PROJECTED ACCRUAL: Approximately 480 patients (240 randomized) will be accrued for this
study within 48 months.
