Resumen
Fecha de inicio: 1 de mayo de 2003
Fecha en la que se inscribió al primer participante.OBJECTIVES: Primary * Compare time to progression in patients with androgen-independent prostate cancer and bone metastases treated with docetaxel with vs without imatinib mesylate. Secondary * Compare the response rates in patients treated with these regimens. * Compare the toxic effects of these regimens in these patients. * Compare quality of life of patients treated with these regimens. OUTLINE: This is a randomized, double-blind, placebo-controlled study. Patients are stratified according to hemoglobin (< 11g/dL vs ≥ 11 g/dL), alkaline phosphatase (normal vs elevated), number of prior regimens (0 vs 1 or 2), and ECOG performance score (0 or 1 vs 2). Patients are randomized to 1 of 2 treatment arms. * Arm I: Patients receive docetaxel IV on days 1, 8, 15, and 22 and oral imatinib mesylate once daily on days 1-43. * Arm II: Patients receive docetaxel as in arm I and oral placebo once daily on days 1-43. In both arms, courses repeat every 43 days in the absence of disease progression or unacceptable toxicity. Patients who progress on arm II may cross over to arm I. PROJECTED ACCRUAL: A total of 152 patients (76 per treatment arm) will be accrued for this study.
