简要总结
This study is evaluating the efficacy of cabazitaxel and hormonal treatment as neoadjuvant treatment for patients with clinically operable disease suitable for surgery, and a high risk of relapse after surgery
详细描述
This study is evaluating the efficacy of cabazitaxel and hormonal treatment (LHRH analogues) as neoadjuvant treatment for patients with clinically operable disease suitable for surgery (no lymph node, visceral or bony metastases), and a high risk of relapse after surgery (5 year risk of relapse).
Patients will receive four cycles of neoadjuvant treatment (cabazitaxel treatment and 3 months LHRH treatment) unless there is evidence of disease progression, unacceptable toxicity or patient request to withdraw consent.

Chronic stable atrial fibrillation on stable anticoagulant therapy is allowed.
研究组 & 干预措施
treatment
14 days prior to starting Cabazitaxel patients will take 50mg Bicalutamide once daily for 21 days.
7 days prior to starting Cabazitaxel patients will be given 3 months LHRH treatment via injection. The entire dose will be administered via one injection 7 days prior to starting Cabazitaxel. This may be either leuprorelin or goserelin acetate and should be given as per local practice.
At least 30 minutes prior to each administration of Cabazitaxel, patients will be administered IV premedication consisting of:
50mg Ranitidine 10mg Chlorphenamine 8mg Dexamethasone Daily from Day 1 until end of Cabazitaxel treatment patients will take 10mg Prednisolone once daily from Day 1 until end of Cabazitaxel treatment Day 1 of each cycle - Patients will receive Cabazitaxel 25 mg/m2 intravenously over one hour every 21 days (on Day 1 of each cycle). Treatment will be continued for 4 cycles.
干预措施: Cabazitaxel (Drug)
结局指标
主要结局
To assess the efficacy activity of neoadjuvant Cabazitaxel chemotherapy and hormonal therapy in patients with high risk operable prostate cancer, measuring the reduction in treatment failure and comparing this to that obtained in the control arm
时间窗: through study completion, average 3 years
Treatment failure is defined as: PSA level ≥ 0.12ng/ml measured on at least two occasions (1 confirmatory sample) post-surgery within three years of follow-up or death related to prostate cancer or use of a salvage therapy or not undergoing surgery at all.)
