Criteria

Eligibility Criteria:

• Male 18 years of age.

• Patients must have stopped bisphosphonates 28 days prior to study entry.

• No prior malignancy allowed except for adequately treated basal cell or squamous cell skin cancer, or adequately treated stage I or II cancer from which the patient is currently in remission, and has been disease free for at least 5 years.

• Patients must have recovered from major infections and/or surgical procedures, and in the opinion of the investigator not have significant active concurrent medical illness, such as a history of significant neurologic or psychiatric disorders including psychotic disorders, dementia, or seizures that would preclude protocol treatment or survival.
