Resumen
Fecha de inicio: 1 de junio de 2000
Fecha en la que se inscribió al primer participante.OBJECTIVES: * Compare the time to progression in patients with hormone refractory prostate cancer treated with dexamethasone with or without SU5416. * Determine the differences in PSA kinetics and PSA hazard score between these two regimens in this patient population. * Determine the objective response rate and time to development of new lesions in these patients treated with SU5416. * Determine the toxicity of SU5416 in these patients. OUTLINE: This is a randomized study. Patients are randomized to one of two treatment arms. * Arm I: Patients receive oral dexamethasone once a day 6 days a week. Treatment continues until disease progression, at which time patients cross over to arm II. * Arm II: Patients receive oral dexamethasone as in arm I followed by SU5416 IV over 60 minutes twice weekly for 4 weeks. A smaller dose of dexamethasone is administered the day after SU5416. Treatment continues for a minimum of 2 courses in the absence of unacceptable toxicity or disease progression. PROJECTED ACCRUAL: A total of 60 patients (30 per arm) will be accrued for this study within 16 months.
