A Randomized Phase II Trial of Bone-Targeted Therapy Consisting of Strontium-89 and Doxorubicin With or Without Celecoxib in Androgen-Independent Prostate Cancer
A Randomized Phase II Trial of Bone-Targeted Therapy Consisting of Strontium-89 and Doxorubicin With or Without Celecoxib in Androgen-Independent Prostate Cancer
RATIONALE: Drugs used in chemotherapy, such as doxorubicin, work in different ways to stop tumor cells from dividing so they stop growing or die. Strontium-89 may relieve bone pain caused by prostate cancer. Celecoxib may stop the growth of cancer by stopping blood flow to the tumor and by blocking the enzymes necessary for tumor cell growth. Combining doxorubicin and strontium-89 with celecoxib may kill more tumor cells.
PURPOSE: This randomized phase II trial is studying celecoxib together with doxorubicin and strontium-89 to see how well they work compared to doxorubicin and strontium-89 alone in treating patients with progressive androgen-independent prostate cancer and bone metastases.
OBJECTIVES:
OUTLINE: This is a randomized study. Patients are stratified according to extent of bone metastases on bone scan (> 20 lesions vs ≤ 20 lesions) and quality of response (i.e., decline of the prostate-specific antigen from baseline) to prior induction chemotherapy (≥ 80% vs < 80%). Patients are randomized to 1 of 2 treatment arms.
PROJECTED ACCRUAL: A total of 70 patients (35 per treatment arm) will be accrued for this study within 18 months.
DISEASE CHARACTERISTICS:
Diagnosis of androgen-independent prostate cancer
Progressive disease after response to prior induction chemotherapy (prostate-specific antigen decline of at least 50% from baseline after 16 weeks of treatment)
No symptomatic lymphadenopathy (i.e., scrotal or pedal edema)
