Efficacy Study Evaluating Chemotherapy in Prostate Cancer — SensiCab  

Prostate Cancer Clinical Trial

Official title: Randomized Phase III Trial Comparing Cabazitaxel Combination Hormone Therapy to Hormone Therapy Alone in Metastatic Prostate Cancer or High Risk Disease

Status Recruiting

Clinical Trial Summary

This clinical trial is designed on the basis of an unmet clinical need, as well as other factors including: 1) the ability to identify subjects at high risk of dying early from their disease, 2) the fact that hormonal therapy has already been shown to improve survival when applied early in the natural history, 3) the availability of chemotherapy such as cabazitaxel that can improve survival in subjects with advanced disease and 4) that chemotherapy (docetaxel) given concomitant with hormone treatment has proven to prolong time to progression.

It is the investigators hypothesis that a more appropriate group of patients who may benefit from the curative potential of systemic chemo-hormonal modality is that with minimal, but detectable disease who have a high probability of developing metastatic disease, clinical symptoms and eventually death from prostate cancer in a defined time frame. The investigators hypothesize further that the approach is likely to be more effective at a time of minimal tumour burden, resulting in minimization of the overall burden of therapy and better quality of life while on treatment.

This trial will determine whether any benefit is gained by adding chemotherapy before hormonal therapy to hormonal therapy alone in the population of subjects with metastatic or high risk disease.

Clinical Trial Description

This clinical trial is designed on the basis of an unmet clinical need, as well as other factors including: 1) the ability to identify subjects at high risk of dying early from their disease, 2) the fact that hormonal therapy has already been shown to improve survival when applied early in the natural history, 3) the availability of chemotherapy such as cabazitaxel that can improve survival in subjects with advanced disease and 4) that chemotherapy (docetaxel) given concomitant with hormone treatment has proven to prolong time to progression.

It is the investigators hypothesis that a more appropriate group of patients who may benefit from the curative potential of systemic chemo-hormonal modality is that with minimal, but detectable disease who have a high probability of developing metastatic disease, clinical symptoms and eventually death from prostate cancer in a defined time frame. The investigators hypothesize further that the approach is likely to be more effective at a time of minimal tumour burden, resulting in minimization of the overall burden of therapy and better quality of life while on treatment.

This trial will determine whether any benefit is gained by adding chemotherapy before hormonal therapy to hormonal therapy alone in the population of subjects with metastatic or high risk disease. Two therapeutic approaches will be compared in this two-arm randomized clinical trial. The control Arm A provides hormonal therapy alone. The experimental Arm B involves treatment with hormone therapy + Cabazitaxel 25 mg / m² / day on day 1 every 3 weeks continued if the patient has stable or responding disease up to 10 cycles. For the schematic representation of study design please see Section 7.3.1.

Subjects with primary metastatic or N+ or high risk disease (PSA>100) will be eligible. The primary endpoint of the trial is overall survival.

Based on the yearly number of prostate cancer patients who are diagnosed with metastatic or high risk disease, approximately 1200 men per year (if +15% improvement)are potential candidates for this approach in the Scandinavian countries . ;
