Toremifene Citrate for Prevention of Bone Fractures in Men With Prostate Cancer on Androgen Deprivation Therapy

Phase 3
Completed
Conditions
Prostate Cancer
Osteoporosis
Fractures
Registration Number
NCT00129142
Lead Sponsor
GTx
Brief Summary

Androgen deprivation therapy (ADT) treatment for prostate cancer decreases the natural hormone called testosterone. This type of therapy is very effective for the treatment of prostate cancer. However, one of the side effects is bone loss or thinning of the bones that can lead to osteoporosis and an increased risk of bone fractures (breaking of the bones). The purpose of the study is to determine whether or not the addition of toremifene citrate (the study drug) to therapy can prevent or decrease the number of bone fractures and to evaluate its impact on side effects associated with testosterone reduction therapy.

  • Have any disease or condition that would preclude an accurate evaluation of radiographs of the thoracic and lumbar spine (at least eight evaluable vertebrae in the range T4 to L4) [for example, severe scoliosis, or sequelae of orthopedic procedures or other surgery]
  • Have > 4 vertebral fragility fractures
  • Have any history of other carcinomas within the last 5 years (except nonmelanoma cutaneous malignancies and superficial bladder cancer with no evidence of recurrence which will not be excluded). NOTE: Patients with cancers other than nonmelanoma cutaneous malignancies and superficial bladder cancer with no evidence of tumor recurrence for at least 5 years after definitive treatment will not be excluded from this study.
  • Have Paget's disease of bone
  • Have active systemic viral, bacterial or fungal infections requiring treatment
  • Have, in the judgment of the investigator, a clinically significant concurrent illness or psychological, familial, sociological, geographical or other concomitant condition that would not permit adequate follow-up and compliance with the study protocol for the full 24-month duration of the study
  • Received treatment with other investigational agents within 30 days prior to randomization
  • Taking finasteride (e.g., Proscar®), dutasteride (e.g., Avodart®), Danocrine® (danazol) or testosterone-like supplements, such as dehydroepiandrosterone (DHEA) [subject is eligible if he stops these agents for a total washout of 45 days prior to randomization and agrees not to use these agents for the duration of the study]
  • Taking herbal medicine or dietary supplements for prostate health, such as PC SPES and saw palmetto (also known as Serenoa repens) [subject is eligible if he stops these agents for a total washout of 45 days prior to randomization and agrees not to use these agents for the duration of the study].
