Phase II Study of the Use of Neoadjuvant Cabazitaxel With Hormonal Treatment in Patients With High Risk Operable Prostate Cancer, to Assess the Efficacy and Toxicity of Cabazitaxel, and, to Explore Potential Predictive and Prognostic Markers of Clinical Outcome

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

Study Overview

• Status: Not yet recruiting
• Conditions: Prostate Cancer
• Intervention / Treatment: Drug: Cabazitaxel

Detailed Description

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.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
NO_INTERVENTION: control; Immediate surgery (radical prostatectomy) (standard care)
EXPERIMENTAL: 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.	Drug: Cabazitaxel; 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 unless disease progression, unacceptable toxicity or patient request. These patients will have surgery (radical prostatectomy) 4-86 weeks following treatment. *Cabazitaxel dose should be capped at 50mg (BSA=2); Other Names: jevtana, XRP6258, RPR116258A

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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	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.)	through study completion, average 3 years

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
• To assess the efficacy of neoadjuvant Cabazitaxel chemotherapy and hormonal therapy, measuring the pathological and radiological response rates and comparing this to that obtained in a control arm of immediate surgery.	Pathological response rate assessed as per pTNM staging system Radiological response rates as defined in RECIST V1.1 Combined to give overall response rate	3 year follow up
To assess the efficacy of neoadjuvant Cabazitaxel chemotherapy and hormonal therapy, assessing surgical margin involvement and comparing this to that obtained in a control arm of immediate surgery.	The proportion of patients with positive resection margin will be reported and compared across the treatment groups using Chi-square tests. Multivariable models using logistic regression techniques shall be used to adjust for key prognostic variables of interest.	3 year follow up
To assess the efficacy of neoadjuvant Cabazitaxel chemotherapy and hormonal therapy, assessing lymph node involvement and comparing this to that obtained in a control arm of immediate surgery.	The proportion of patients with positive lymph nodes will be reported and compared across the treatment groups using Chi-square tests.	3 year follow up
To assess the efficacy of neoadjuvant Cabazitaxel chemotherapy and hormonal therapy, measuring progression free survival and comparing this to that obtained in a control arm of immediate surgery.		3 year follow up
• To assess the efficacy of neoadjuvant Cabazitaxel chemotherapy and hormonal therapy, measuring overall survival from time of randomisation to death and comparing this to that obtained in a control arm of immediate surgery.		3 year follow up
To assess the efficacy of neoadjuvant Cabazitaxel chemotherapy and hormonal therapy, measuring surgical feasibility and comparing this to that obtained in a control arm of immediate surgery.	The proportion of patients with delays to surgery, perioperative morbidities, mortalities and surgical complications will be reported and compared across the treatment groups.	3 year follow up
To assess the quality of life of patients receiving neoadjuvant Cabazitaxel chemotherapy and hormonal therapy and comparing this to quality of life patients in a control arm of immediate surgery using the EORTC QLQ-C30 version 3 questionnaire.	Responses to EORTC QLQ-C30 will be reported (median, IQR) according to global health status, the functional scales and symptom scales, by intervention group, and over time. Joint modelling or quality-adjusted survival analysis will be undertaken to allow a simultaneous assessment of quality of life and survival.	3 year follow up
