Exclusion Criteria:

  • Patients taking regular oral steroids, above the allowed limit of 10mg/day methylprednisolone or analogues, for any reason. Patients must not have had steroids for 28 days prior to study entry.

  • Evidence of significant uncontrolled concomitant disease that could affect compliance with the protocol or interpretation of results.
  • Active or untreated CNS metastases as determined by computed tomography (CT) or magnetic resonance imaging evaluation during screening and prior radiographic assessments.
  • Patients with treated asymptomatic CNS metastases are eligible, provided they meet all of the following criteria: 1. Evaluable or measurable disease outside the CNS 2. No metastases to midbrain, pons, medulla, or within 10 mm of the optic apparatus (optic nerves and chiasm) 3. No history of intracranial or spinal cord hemorrhage 4.

Subjects with clinically relevant ongoing complications from prior surgery are not eligible.

Patients who are receiving bisphosphonate therapy or denosumab specifically to prevent skeletal events and who do not have a history of clinically significant hypercalcemia are eligible. Patients who are receiving denosumab prior to enrollment must be willing and eligible to receive a bisphosphonate instead while on study.
