NCT00426777

Brief Summary

Prostate cancer patients treated with LHRH agonists (e.g., leuprolide) lose bone mineral density. This is similar to post-menopausal osteoporosis. Risedronate is approved to prevent osteoporosis. We hypothesize that risedronate may also be effective in prostate cancer patients treated with LHRH agonists.

You may qualify if:

  • Patients over 18 years of age.
  • Histologically confirmed diagnosis of prostate cancer without metastases.
  • Patient must have negative bone scan to rule out bone metastases.
  • Patient for whom androgen deprivation therapy with leuprolide acetate is indicated for at least 1 year.
  • Eastern Cooperative Oncology Group (ECOG) score of 0 - 2.
  • Study medication must be started within 3 months of initiation of ADT.
  • Signed written informed consent.

You may not qualify if:

  • Prior ADT (greater than 3 months).
  • History of treatment with calcitriol or bisphosphonates.
  • Suppressive doses of thyroxine within the previous year.
  • Concomitant or prior history of long-term treatment (greater than or equal to 3 months) with systemic glucocorticoids.
  • Evidence of any of the following conditions per subject self-report or chart review:
  • Current hyper- or hypothyroidism (stable on thyroid replacement therapy is allowed, if TSH is within normal reference range).
  • Paget's disease, Cushing's disease, hyperprolactinemia, chronic liver disease. Unstable systemic disease including active infection, uncontrolled hypertension, unstable angina, congestive heart failure, or myocardial infarction within 6 months before randomization.
  • Major surgery or significant traumatic injury occurring within 1 month prior to randomization.
  • Known hypersensitivity to leuprolide acetate or any of the components found in Eligard
  • Any concurrent condition that would make it undesirable, in the physician's opinion, for the subject to participate in the study or would jeopardize compliance with the protocol.
