NCT03336983.

Study name BonEnza
Methods Recruitment period:
  • December 2017 to still recruiting


Endpoints:
  • evaluation of change in bone response after 6 and 12 months of treatment compared to baseline

  • evaluation of bone repair

  • changes in bone mineral density after 18 months of treatment compared to baseline

  • Functional Assessment of Cancer Therapy‐Prostate (FACT‐P) Questionnaire, including a global quality of life score

  • Brief Pain Inventory‐Short Form Questionnaire (BPI‐SF)

  • weight evaluation

  • C‐terminal telopeptide analysis (CTX, ng/mL)

  • bone alkaline phosphatase analysis


Randomization:
  • intervention vs control

Participants Eligibility criteria:
  • histological diagnosis of prostate carcinoma

  • age > 18 years

  • metastatic disease documented as the presence of bone lesions on bone scan associated or not to soft tissue lesions measurable at computed tomography scan or magnetic resonance imaging

  • no previous hormone or chemotherapeutic treatments given for prostate carcinoma (patients receiving gonadotropin‐releasing hormone (LHRH) analogues therapy for less than 4 months are admitted)

  • Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1

  • expected life expectancy ≥ 6 months

  • patient capable of swallowing study medication and complying with study requirements

  • signed informed consent


Exclusion criteria:
  • presence of active serious disease, active infection, or comorbidity that may prevent study enrollment (at the discretion of the clinical investigator)

  • known or suspected brain metastases or active leptomeningeal dissemination

  • history of other malignant neoplasm except non‐melanoma skin carcinoma during the previous 5 years

  • absolute neutrophil count < 1500/µL, platelet < 100,000/µL, or hemoglobin < 5.6 mmol/L (< 9 g/dL) at screening visit (notably: patients must not receive any growth factor during the previous 7 days or any blood transfusion during the 28 days preceding the hematology sampling performed at screening)

  • total bilirubin, alanine aminotransferase, or aspartate aminotransferase > 2.5 x upper limit of normal at screening visit

  • creatinine > 177 µmol/L (> 2 mg/dL) at screening visit

  • albumin ≤ 30 g/L (≤ 3.0 g/dL) at screening visit

  • history of seizures or any other seizure‐predisposed pathology; history of loss of consciousness or transitory ischemic attack during the 12 months preceding the screening visit

  • clinically significant cardiovascular disease including:

    • myocardial infarction (6 months preceding the screening)

    • uncontrolled angina (3 months preceding the screening)

    • congestive heart failure New York Heart Association (NYHA) class 3 or 4, congestive heart failure NYHA class 3 or 4 in the past, unless a screening echocardiogram or multigated acquisition scan performed within 3 months results in a left ventricular ejection fraction ≥ 45%

    • history of clinically significant ventricular arrhythmias (e.g. ventricular tachycardia, ventricular fibrillation, torsades de pointes)

    • history of Mobitz II second‐ or third‐degree heart block without a permanent pacemaker in place

    • hypotension as indicated by systolic blood pressure < 86 mmHg at the screening visit

    • bradycardia as indicated by a heart rate of < 50 beats per minute on the screening electrocardiogram

    • uncontrolled hypertension as indicated by systolic blood pressure > 170 mmHg or diastolic blood pressure > 105 mmHg at the screening visit

  • gastrointestinal disorder affecting absorption (e.g. gastrectomy, active peptic ulcer disease within last 3 months)

  • major surgery within 4 weeks of enrollment (Day 1 visit)

  • radiation therapy for treatment of the primary tumor within 3 weeks of enrollment (Day 1 visit)

  • use of herbal products that may have hormonal anti‐prostate cancer activity and/or are known to decrease prostate‐specific antigen (PSA) levels (e.g. saw palmetto) or systemic corticosteroids greater than the equivalent of 10 mg of prednisone per day within 4 weeks of enrollment (Day 1 visit)

  • any condition or reason that, in the opinion of the investigator, interferes with the ability of the patient to participate in the trial, which places the patient at undue risk, or complicates the interpretation of safety data


Participants randomized:
  • 120 planned, still recruiting


Country of participants:
  • Italy

Interventions Interventions during study period:
  • enzalutamide

  • enzalutamide + zoledronic acid
