Safety and Efficacy Study of GM-CSF, Thalidomide Plus Docetaxel in Prostate Cancer

Inclusion Criteria: * Diagnosis of adenocarcinoma of the prostate. * Failure of local treatments (surgery and/or radiation) as defined by a rising PSA; demonstrated by at least three consecutive rises in PSA by intervals of at least 4 weeks apart with an absolute change of at least 1 ng/mL. If the confirmatory PSA (third PSA) is less than the previous screening PSA value, an additional test for rising PSA will be required to document progression. * No clinical or radiographic evidence of disease. * The Zubrod performance status 0-1. * Prior hormonal therapy in the form of neoadjuvant or adjuvant therapy is allowed as long as androgen therapy has been completed at least 1 year prior to study entry. * Adequate hematologic function: absolute granulocytes ≥ 1500/ul, platelets ≥ 100,000/ul, hemoglobin ≥ 10 gm/100 ml within 4 weeks prior to study entry. * Adequate hepatic function: bilirubin ≤ 1.5 mg/dl, liver enzymes ≤ 1.5 ULN within 4 weeks prior to study entry. * Adequate renal function: creatinine ≤ 1.5 x ULN within 4 weeks prior to study entry. * Patients treated with bisphosphonate therapy before or after study entry are eligible to continue in the study. * Negative bone scan within 6 weeks prior to study entry. * Negative CT scan or MRI of the abdomen and pelvis within 6 weeks prior to study entry. * Negative chest x-ray for metastatic disease within 6 weeks prior to study entry. * Patients must sign a written informed consent prior to treatment. Exclusion Criteria: * Serious intercurrent medical illness including symptomatic heart disease within 6 months. * Previous or concurrent invasive cancers other than superficial non-melanomatous skin cancer unless disease-free for at least 5 years. * Major medical or psychiatric illness which, in the investigator's opinion, would prevent completion of treatment and would interfere with follow-up. * History of thromboembolic events (deep venous thrombosis, symptomatic cerebrovascular events or pulmonary embolism), history of MI, within the last 12 months. * History of bleeding disorders that would contraindicate Coumadin® (warfarin) including: esophageal varices and clotting factor defects
