入选标准

  • 1. Patients aged 18 years and above, willing and able to provide written informed consent.
  • 2. Prostate adenocarcinoma with histological or cytological confirmation without neuroendocrine differentiation nor small cell characteristics
  • 3. Androgen deprivation therapy with GnRH analogs or bilateral orchiectomy (pharmacological or surgical castration). Patients without bilateral orchiectomy must follow a GnRH analog therapy during the trial.
  • 4. Testosterone serum level <= 1,73 nmol/L (50 ng/dL) in screening visit.
  • 5. Patients under bisphosphonate therapy must have received stable doses for the last 4 weeks.
  • 6. Progression disease at inclusion, defined by one or more of the following three criteria during androgen deprivation therapy (according with the criterion nº 3):
  • - PSA progression defined as two elevation of the PSA serum level with >=1 week between each measure. Patients who have received an antiandrogen must present disease progression (>=4 weeks since the last dose of flutamide or >=6 weeks since the last dose of bicalutamide or nilutamide). PSA value in screening visit must be >=2 µg/L (2 ng/mL).
  • - Soft tissue progression defined by RECIST 1.1 criteria
  • - Bone lesion progresión defined by PCWG2 criteria, with two or more new lesions in a scintigraphy
  • 7. Metastatic disease with bone lesions detected by scintigraphy, or measurable soft tissue lesions by CT/MR. Patients with ganglionar disease will be suitable if they have at least one ganglionar lesion with smallest diameter > 2,5 cm.
  • 8. Patients without previous cytotoxic chemotherapy for prostate cancer
  • 9. Patients without previous abiraterone acetate therapy for prostate cancer
  • 10. Asymptomatic patient or mild symptomatic about prostate cancer, (answer in the question nº 3 of the Brief Pain Inventory Short From < 4)
  • 11. ECOG = 0-1.
  • 12. Life expectancy of at least 6 months
  • 13. Patient must be able to swallow the investigation product and to follow the protocol requirements.
  • 14. Biomarker study informed consent
  • Are the trial subjects under 18? no
  • Number of subjects for this age range:
  • F.1.2 Adults (18-64 years) yes
  • F.1.2.1 Number of subjects for this age range 30
  • F.1.3 Elderly (>=65 years) yes
  • F.1.3.1 Number of subjects for this age range 68

  • - Platelet count <100 000/µL
  • - Haemoglobin < 5,6 mmol/L (9 g/dL)
  • 5. Liver function: Serum bilirrubin, ALT or AST > 2,5 x ULN
  • 6. Renal function: Creatinine >177 µmol/L (2 mg/dL).
  • 7. Serum albumin <30 g/L (3,0 g/dL)
  • 8. History of epilepsy or other medical condition which could cause an epileptic crisis as syncope or transient ischemic attack in the last twelve months.
  • 9. Clinically significant cardiovascular disease, including:
  • - Myocardial infarction in the last 6 months

  • - History of clinically significant ventricular arrhythmia
  • - History of second degree AV bock or third degree AV block without permanent pacemaker
  • - Hypotension determined by a baseline systolic blood pressure < 86 mmHg
  • - Bradycardia detemined by heart rate < 50 BPM in baseline ECG
  • - Uncontrolled hypertension (systolic BP > 170 mmHg or diastolic BP > 105 mmHg).
  • 10. Known gastrointestinal (GI) disease that could interfere with the GI absorption.
  • 11. Significant surgery within 4 weeks before enrollment.
  • 12. Use of opioids to control cancer pain within 4 weeks before enrollment.
  • 13. Radiation therapy for treatment of the primary tumor in the last 3 weeks before enrollment

  • 21. Prior therapy or enrollment in a trial with an investigational product which blocks androgen synthesis (abiraterona, TAK-700, TAK-683, TAK-448) or blocks androgen receptors (ARN507, BMS 641988).
  • 22. Included in a previous trial with enzalutamide (MDV3100).
  • 23. Administration of an investigational drug in the last 4 weeks before enrollment
