Hormone Therapy Plus Chemotherapy as Initial Treatment for Local Failures or Advanced Prostate Cancer

Stopped early · Phase 2

Conditions studied: Prostatic Neoplasms

In brief

This study is for men who have prostate cancer and have failed local therapy or are not a candidate for prostatectomy or radiation therapy. The purpose of this research study is to assess the safety and benefit of androgen deprivation therapy (ADT, blocks hormones) plus chemotherapy. Degarelix is the hormone blocking drug that will be used. Doxorubicin, Ketoconazole, Docetaxel and Estramustine are the chemotherapy drugs that will be used. The drugs used in this study are approved by the Food and Drug Administration (FDA). Participants will be treated with ADT plus chemotherapy for three, four, or five 8-week cycles (12, 18, or 24 months). The number of cycles of chemotherapy they receive and the number of months they receive ADT will be based on their disease. The current standard treatment is ADT and chemotherapy. What differs in this research study is the cycling and combination of chemotherapy drugs chosen. The drugs chosen for this study have fewer side effects and are believed to provide maximum benefit.

Who can join

Age: 18 and older. Sex: male. Healthy volunteers: not accepted.

You may qualify if…

• Pathologic proof of adenocarcinoma of the prostate.
• Patients must belong to one of the following subsets:
• Prior local therapy
• Patients with Prostate Specific Antigen (PSA) recurrence following prostatectomy or radiation therapy who have no radiographic involvement. PSA doubling time ≤6 months.
• Nodal involvement only.
• Low volume bone disease: ≤3 metastases.
• Nodal involvement with associated bone involvement.
• High volume bone-visceral disease: Patients with >3 metastatic bone sites or visceral metastases.
• No prior definitive local therapy
• Tumors felt to be unresectable, not candidates for radiation therapy, and PSA elevated with biopsy-proven disease.
• Metastatic disease at presentation.
• Patients may have started ADT within 3 months of study entry.
• No previous cytotoxic therapy is allowed, including systemic irradiation with strontium-89, samarium, or radium-223.
• Previous definitive radiotherapy to one metastatic site is acceptable, provided that unirradiated sites remain. At least 8 weeks must have elapsed since radiation therapy to the pelvis. Patients having limited irradiation of a metastatic site are eligible 4 weeks following radiation.
• Patients may have had previous exposure to ADT if it was given for ≤6 months to "downstage" the primary and provided that such therapy was completed at least 12 months prior to entry into this study with a return of serum testosterone to ≥200 ng/dL.
• Patients must be free of serious comorbidity and have a life expectancy of ≥3 years.
• Patients must have adequate physiologic reserves as evidenced by:
• Eastern Cooperative Oncology Group (ECOG) status of ≤2.
• Patients must have adequate bone marrow function: Platelets ≥100,000 cells/mm3, Hemoglobin ≥9.0 g/dL, and Absolute Neutrophil Count (ANC) ≥1,500 cells/mm3.
• Patients must have adequate renal function: creatinine ≤2 × upper limit of normal (ULN).
• Patients must have adequate liver function: Aspartate aminotransferase (AST) / Alanine transaminase (ALT) ≤2.5 × ULN; alkaline phosphatase <2.5 × ULN, unless bone metastasis is present in the absence of liver metastasis; and bilirubin < ULN or 1.5 mg/dl.
• No evidence of active ischemia on electrocardiogram (ECG) and documentation of ejection fraction (EF) ≥50%.

You may not qualify if…

• Patients must not have a second malignancy unless there is confidence of previous curative therapy.
• Patients with a recent history of transient ischemic attack (TIA) (within 6 months), who are requiring regular antianginal therapy, or who are having claudication sufficient to limit activity are not eligible. Patients with a previous history of deep venous thrombosis or pulmonary embolism (within 12 months) are not eligible
• Patients must not have a serious intercurrent medical or psychiatric illness, including serious active infection.
• Patients must not have sensory neuropathy > grade 1.
