E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To demonstrate the superiority of cabazitaxel plus prednisone at 25 mg/m² (Arm A) plus ADT versus ADT plus prednisone (Arm B) in term of progression-free survival (PFS) in hormone-sensitive prostate cancer patients who fail to achieve PSA nadir value after 6 months of LHRH-A therapy for rising PSA after curative therapy. |
|
E.2.2 | Secondary objectives of the trial |
To compare the two study arms for: · biochemical PFS · time to castration-resistance development · metastasis-free survival · overall survival · tolerability · impact on the quality of life |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Patients meeting all of the following criteria will be considered for enrollment into the study: 1. Pathologically confirmed adenocarcinoma of the prostate 2. Absence of distant metastasis at the diagnosis 3. Adequate radical treatment for prostate cancer: the following treatments are allowed for management of initial disease · Radical prostatectomy · External radical radiotherapy · Interstitial brachytherapy 4. Biochemical failure after primary treatment with curative intent (as per EAU 2011 guideline definitions): XML File Identifier: pgnqMWgEieDXnccenPA31nFWt5A= Page 15/25 · After RP: PSA level > 0.2 ng/ml with a second confirmation · After EBRT: PSA level > 2 ng/ml above the nadir · After IB: : PSA level > 2 ng/ml above the nadir 5. ADT for biochemical failure (all LHRH-A formulations and dosages are allowed) according to the daily clinical practice 6. Failure to achieve PSA nadir value after 6 months with ADT: patients who receiving ADT are followed every two months and are evaluated after 6 months of treatment comparing the PSA value to the value which was achieved at the nadir after radical treatment and before biochemical progression. The patients could be classified according to three different conditions: · Good responders to ADT (6-month PSA is equal or less than PSA nadir value) · Partially responders to ADT (6-month PSA is lower than value before ADT start but is greater than PSA nadir value) · Non responders to ADT (6-month PSA is greater than PSA nadir value or is increasing after a transient response) For the purposes of the present study are eligible only the patients partially responders 7. ECOG Performance Status 0 or 1 8. Laboratory requirements at entry EudraCT No. C.HO.SE. Protocol, Version 1.1, July 2012 28 · Absolute neutrophils ≥ 1.5 x 109/L · Platelets ≥ 100 x 109/L, Hemoglobin ≥ 9 g/dl · Serum creatinine <1.5 x ULN (If creatinine 1.0 - 1.5 x ULN, creatinine clearance calculated according to CKD-EPI formula should be ≥60 mL/min) · Serum bilirubin < 1 x UNL ASAT and ALAT < 2.5 UNL 9. Ability to fill the quality of life questionnaire 10. Obtained signed informed consent prior to start protocol specific requirements 11. Patient compliance and geographic proximity that allow adequate follow-up. |
|
E.4 | Principal exclusion criteria |
Patients presenting with any of the following will not be included in the study: 1. Age > 75 years 2. Prior systemic chemotherapy 3. Prior complete androgen blockage 4. Prior ADT for the biochemical failure lasting more than 6 months 5. History of prior malignancies, except for cured non melanoma skin cancer or other cancer curatively treated and with no evidence of disease for at least five years 6. Significant neurological or psychiatric disorders such as dementia that would prohibit them to understanding or rendering informed consent or from fully complying with treatment and follow-up 7. Other serious concomitant illness of medical conditions 8. Any other condition which in the judgment of the investigator would place the subject at undue risk or interfere with the study. |
