A Phase II Trial of Combination Therapy With Celecoxib and Taxotere for the Treatment of Stage D3 Prostate Cancer

Inclusion Criteria

• •Patient must have histologically proven adenocarcinoma of the prostate gland.
• •Patient must have evidence of progressive metastatic disease (e.g., bone, pelvic mass, lymph node, liver or lung metastases) within 6 weeks prior to participation in the study.
• •Patients who have evaluable but not measurable disease must not have an elevated PSA level as the only evidence of disease. While castrated, the patients should have rising PSA on two consecutive measurements at least 1 week apart. The confirmatory PSA must be obtained within 1 week prior to study registration and should be \>10ng/ml.
• •Patients with bone metastases only (i.e., lacking soft-tissue disease) must have a PSA level of \> 10 ng/ml. Patients with soft tissue metastases and /or visceral disease must have either measurable disease or a PSA level of \> 10 ng/ml.
• •Radiological evidence of hydronephrosis will not by itself constitute evidence of metastatic disease.
• •Patients must have had prior treatment with bilateral orchiectomy or other primary hormonal therapy (e.g., estrogen therapy, LHRH analog + flutamide, etc.) with evidence of treatment failure.
• •NOTE: patients who have not undergone bilateral orchiectomy must continue LHRH agonist therapy (e.g., depot leuprolide or goserelin) while receiving this protocol therapy. For these patients the testosterone level should be preferably checked before enrollment and should be \< 50 ng/dl.
• •For patients previously treated with flutamide (Eulexin), nilutamide (Nilandron), or bicalutamide (Casodex): Patients must have discontinued flutamide or nilutamide \< 4 weeks and for bicalutamide 6 weeks prior to registration.
• •Patients must not have received prior treatment with chemotherapy within the last 5 years.
• •Patients must not have had prior radiotherapy \< 4 weeks prior to this protocol treatment.
• •Patients must not have previously received Strontium 89, Samarium 153, or other radioisotope therapies.
• •Patients must have recovered from all toxicities due to prior treatment for prostate cancer prior to receiving this protocol treatment.
• •Patients must have adequate bone marrow function: (WBC \> 4000/ mm3, granulocytes \> 1500/ mm3, platelet count \> 100,000/mm3, and Hemoglobin \> 8.0 g/dl \< 4 weeks prior to participate in this study.
• •Patients must have the following chemistry values \< 4 weeks prior to participate in this study:
• •Total bilirubin must be within normal limits.
• •Creatinine \< 2.0 mg/d. or creatinine clearance \> 50 ml/min
• •Transaminases (SGOT and/or SGPT) may be up to 2.5 x institutional upper limit of normal (ULN) if alkaline phosphastase is \< ULN, or alkaline phosphastase may be up to 4 x ULN if transaminases are \< ULN.
• •Peripheral neuropathy must be \< grade 1
• •Patients must have no active angina pectoris, or known heart disease of New York Heart Association Class III-IV. Patients must not have a history of myocardial infarction \< 6 months prior to the study participation.
• •Patients with a history of prior malignancy are eligible provided they were treated with curative intent and have been free of disease for the time period considered appropriate for the specific cancer.
• •No serious concurrent medical illness or active infection should be present which would jeopardize the ability of the patient to receive the chemotherapy outlined in this protocol with reasonable safety.
• •Sexually active patients must use an accepted and effective method of contraception while receiving protocol treatment.
• •Patients must have a Karnofsky Performance Scale (KPS) score over 50. (equaling ECOG Performance Scale of 0, 1, or 2).
• •Age \> 18 years
