  • Liver function:
  • Serum bilirubin ≤ 1.5 x ULN (except for patients with documented Gilbert's disease),
  • AST and ALT ≤ 1.5 x ULN (and ≤ 5 ULN in case of liver metastases),
  • ALK-P ≤ 2.5 x ULN (in case of bone metastasis, ALK-P<1000U/L if bilirubin is normal) 8. Patients must have received ADT for a maximum of 3 months before randomization and there must be a minimum of 6 weeks between the start of ADT and the start of Docetaxel, 9. Patients willing and clinically fit to receive Docetaxel which is defined by the following :
  • Patients respecting all inclusion and exclusion criteria And

Patients might have received previous radiation therapy directed to bone lesions, 11. Patients able to take oral medication, 12. Patients who have received the information sheet and signed the informed consent form, 13. Male patients who will receive Docetaxel and/or Abiraterone acetate and have partners of childbearing potential and/or pregnant partners must use a method of birth control in addition to an adequate barrier protection (condoms) as determined to be acceptable by the study doctor during the treatment period and for 4 weeks after the last dose of abiraterone acetate and/or for 6 months after the last dose of Docetaxel 14. Patients must be willing and able to comply with scheduled visits, treatment plan, laboratory tests and other study procedures, 15. Patients with a public or a private health insurance coverage, according to local laws for participation in clinical trials.

Exclusion Criteria:

  • And
  • Patients with no contraindication to docetaxel according to the SmPC of the drug And
  • Patients presenting all medical requirements to receive docetaxel according to the investigator's opinion. 10. Patients might have received previous radiation therapy directed to bone lesions, 11. Patients able to take oral medication, 12. Patients who have received the information sheet and signed the informed consent form, 13. Male patients who will receive Docetaxel and/or Abiraterone acetate and have partners of childbearing potential and/or pregnant partners must use a method of birth control in addition to an adequate barrier protection (condoms) as determined to be acceptable by the study doctor during the treatment period and for 4 weeks after the last dose of abiraterone acetate and/or for 6 months after the last dose of Docetaxel 14. Patients must be willing and able to comply with scheduled visits, treatment plan, laboratory tests and other study procedures, 15. Patients with a public or a private health insurance coverage, according to local laws for participation in clinical trials. Exclusion Criteria: 1. Patients with previous definitive local treatment directed to the prostate primary cancer (radiotherapy, brachytherapy, radical prostatectomy, ultrasound, cryotherapy, or other). A previous trans-urethral resection of the prostate (TURP) and previous local treatments of metastase are allowed, 2. Prior cytotoxic chemotherapy or biological therapy for the treatment of prostate cancer, 3. Any chronic medical condition requiring a higher dose of corticosteroid than 5 mg prednisone/prednisolone twice daily, 4. Active infection or other medical condition for which prednisone/prednisolone (corticosteroid) use would be contra-indicated, 5. Previously treated with ketoconazole for prostate cancer for more than 7 days, 6. Prior systemic treatment with an azole drug (e.g. fluconazole, itraconazole) within 4 weeks of randomization, 7. Hypertension not controlled by an anti-hypertensive treatment (systolic BP ≥ 160 mmHg or diastolic BP ≥ 95 mmHg; 3 consecutive measures taken 5 minutes apart), 8. Severe or moderate hepatic impairment (Child
  • Pugh class C or B) 9. Active or symptomatic viral hepatitis or chronic liver disease (except Gilbert's disease), 10. History of pituitary or adrenal dysfunction, 11. Clinically known significant heart disease as evidenced by myocardial infarction, or arterial thrombotic events in the past 6 months, severe or unstable angina, or New York Heart association (NYHA) Class II-IV heart disease or cardiac ejection fraction measurement of < 50% at baseline, 12. Atrial Fibrillation, or other cardiac arrhythmia requiring therapy, 13. Patient with unstable pulmonary disease (eg. Pulmonary embolism) 14. Pathological finding consistent with small cell carcinoma of the prostate, 15. History of malignancy, except non-melanoma skin cancer, with a ≥ 30% probability of recurrence within 24 months, 16. Known allergies, hypersensitivity or intolerance to the study drugs or excipients or docetaxel 17. Administration of an investigational therapeutic within 30 days of randomization, 18. Patients already included in another therapeutic trial involving an experimental drug (patient in a non-experimental trial with no modification of the patient's care can be included), 19. Patients with significantly altered mental status prohibiting the understanding of the study or with psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule or any condition which, in the opinion of the investigator, would preclude participation in this trial. Those conditions should be discussed with the patient before registration in the trial, 20. Individual deprived of liberty or placed under the authority of a tutor. 21. Patients with impaired vision should undergo a prompt and complete ophtalmologic examination. Patients with Cystoid Macular Oeadema cannot be included due to a potential risk of deterioration associated with docetaxel. 22.
