Disegno dello studio
Allocation: Randomized. Intervention model: Parallel Assignment. Primary purpose: Treatment. Masking: None (Open Label). (ICTRP)

Criteri di inclusione/esclusione
Gender: Male
Maximum age: N/A
Minimum age: 18 Years
Inclusion criteria:

1. Histologically or cytologically confirmed adenocarcinoma of the prostate,

2. Metastatic disease documented by a positive bone scan (any technique) or CT scan or
an MRI. For patients with nodal metastases only, only patients with extra-pelvic
enlarged lymph nodes (lymph nodes located above the iliac bifurcation) can be
included if they have either:

o At least one extra-pelvic lymph node = 2 cm or extra-pelvic lymph node (s) = 1 cm
if the patients also have at least one pelvic lymph node = 2 cm

3. Patients with ECOG = 1 (patient with PS 2 due to bone pain can be accrued in the
trial),

4. Life expectancy of at least 6 months,

5. Male aged = 18 years old and = 80 years old ,

6. Hematology values:

- Hemoglobin = 10.0 g/dL,

- Platelet count = 100,000/mL,

- Neutrophil = 1500 cells/mm?

7. Biochemistry values:

- Renal function: Serum creatinine < 1.5 x ULN or a calculated creatinine
clearance = 60 mL/min,

- Serum potassium = 4 mmol/L,

- 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 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 metastases 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 in the past 6 months as evidenced by
myocardial infarction, or arterial thrombotic events, 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 ophthalmologic
examination.

Patients with Cystoid Macular Oedema cannot be included due to a potential risk of
deterioration associated with docetaxel.

22. Concomitant use of strong CYP3A4 inhibitors (clarithromycin, indinavir, nefazodone,
nelfinavir, ritonavir, saquinavir, telithromycin.) (ICTRP)
