Postmenopausal Bone Loss
|Study Design:||Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Factorial Assignment
Primary Purpose: Treatment
|Official Title:||A Randomized Study of the Effects of Tibolone on Bone Density, Menopause Symptoms and Breast Density in High Risk Women After Prophylactic Oophorectomy|
- To compare bone mineral density and markers of bone turnover following oophorectomy in patients receiving tibolone versus placebo
- To compare changes in menopausal symptoms and mammographic breast density in women taking tibolone to women taking placebo
|Study Start Date:||April 2004|
|Study Completion Date:||March 2006|
|Primary Completion Date:||March 2006 (Final data collection date for primary outcome measure)|
Women interested in participating in this study will be allowed to use hormones to manage symptoms for up to 3 months before beginning the study. Those choosing not to take hormones may enroll in the study immediately.
All women will have a baseline mammogram, breast examination, and bone study density performed, along with blood and urine analysis for measurement of bone markers. They will also be asked to take a questionnaire.
Patients will take either tibolone or placebo once daily for 1 year. Neither the patient or the physician will be aware of which treatment a woman is taking during the study.
Patients will return at 6 and 12 months to have a physical examination, blood work, urine collection and bone studies. At one year, a repeat mammogram will be performed. There are also some questionnaires asking about menopause symptoms that will be performed at intervals during the study.
It is also recommended that patients take calcium and vitamin D throughout the study.
