简要总结
The purpose of this study is to assess the relative efficacy and toxicity of combination therapy of GM-CSF, Thalidomide plus Docetaxel in patients with prostate cancer with a rising PSA.
详细描述
As more men are being diagnosed and treated for prostate cancer at an early age, the number who experiences a rising level of prostate-specific antigen (PSA) after initial treatment is increasing, affecting approximately 50,000 patients each year.
These three drugs are commercially available. Thalidomide is an angiogenesis inhibitor which blocks the development of new blood vessels. GM-CSF stimulates the body's immune response to fight cancer. Docetaxel is the most active chemotherapeutic agent in the treatment of prostate cancer. GM-CSF and thalidomide have proven activity in suppressing PSA values.
This study design offers an opportunity to add cytotoxic therapy (docetaxel) in combination with an active pathobiologic regimen (GM-CSF plus thalidomide) to eradicate micrometastatic disease, thus potentially offering a significant delay to clinical failure as measured by a rise in PSA or radiographic involvement. Additionally, delays in the use of hormone therapy has the potential to be of significant benefit.
GM-CSF will be administered at a fixed dose 3 days per week by subcutaneous injection for 12 months. Participants will receive a fixed dose of thalidomide orally at bedtime daily without interruption for 12 months. Docetaxel will be administered intravenously over 1 hour on week 1 of every cycle (every 3 weeks) for 18 weeks.

入选标准
- •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-
- •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.
排除标准
- •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
