简要总结

Studies objectives:

To evaluate the safety, tolerability and efficacy of ACC given in combination with ZA or with Denosumab as compared to placebo given with ZA or with Denosumab as outline below:

  • Safety and Tolerability:
  • Adverse events (AEs) and serious AEs
  • Safety laboratory measurements
  • Hypercalcemic and hypercalciuric episodes
  • Treatment withdrawal due to AEs and overall

Efficacy:

  • Skeletal Related Events (SREs)
  • Measurable and evaluable disease progression
  • Progression Free Survival (PFS)
  • Pain assessment via the VAS scale

入选标准

  • Age > 18 year
  • Histologic proof of Castrate Resistant Prostate Cancer with Bone Metastasis
  • Systemic steroids are only allowed if needed for hormonal therapy
  • Previous radiation therapy must have been completed more than four weeks prior to enrollment into this study, unless subjects are under radiotherapy as a rescue therapy. Subjects must have recovered from all side effects.
  • The last dose of chemotherapy must have been completed at least four weeks prior to enrollment into this study, and subjects must have recovered from all side effects.
  • Subjects must have a performance status of 0-2 by the ECOG Scale.
  • Subjects must have pretreatment (obtained < 7 days prior to treatment) granulocyte count of > 2,000/μL, platelet count of > 100,000/μL, WBC > 3,000/μL, hemoglobin ≥ 10.0 g/dL, serum creatinine < 1.5 mg/dL, bilirubin < 1.5 mg/dL, and ALT/AST not more than 3x the upper limit of normal (or not more than 5x if the elevation is due to liver metastases).
  • Subjects must be normo-calcemic upon study entry.
  • Subjects must be Vitamin D sufficient upon study entry, which is defined as 25(OH)D serum level >20 ng/mL (50 nmol/L) according to a document composed by the Food and Nutrition Board of the Institute of Medicine, USA. If the subject is Vitamin D insufficient or deficient, then a loading dose of Vitamin D3 will be administered as follows:
  • If the serum 25(OH)D level is 12-20 ng/mL (30-50 nmol/L) then a loading oral dose of 50,000 IU of Vitamin D3 should be administered twice with 3-5 days in between the doses.
  • If the serum 25(OH)D level is ≤ 12 ng/mL (30 nmol/L), then a loading oral dose of 50,000 IU of Vitamin D3 will be administered three times with 3-5 days in between the doses. Serum 25(OH)D levels will be checked 1-2 weeks following the last loading.
  • Regardless of Vitamin D levels, all subjects will receive a daily maintenance dose of 1000 IU Vitamin D3, which should be taken in the morning with breakfast.
  • Estimated life expectancy of > 3 months.
  • Subjects must be accessible for follow-up.
  • Written informed consent will be obtained.

排除标准

  • Concurrent treatment with acute anticancer therapy
  • Hormonal and corticosteroid therapies for Skeletal Related Events are not allowed
  • Sarcoidosis
  • Hypercalcemia
  • Hypophosphatemia
  • Hypoparathyroidism/Hyperparathyroidism
  • Major surgery within 4 weeks of anticipated inception of AMOR-1therapy
  • Serious intercurrent infections or non-malignant medical illnesses that are uncontrolled or whose control may be jeopardized by the complications of therapy
  • Psychiatric disorders rendering subjects incapable of complying with the requirements of the protocol
  • Any illness or condition deemed by the investigator to contra-indicate treatment with AMOR-1 or ZA or Denosumab
  • Hypersensitivity to ZA or Denosumab or Abiraterone acetate or Enzalutamide, or to any bisphosphonates or to any of the following excipients: Mannitol and Sodium citrate.
  • Active cancer treatment except hormonal
