Efficacy of Tibolone Versus Transdermal E2/NETA on Sexual Function in Naturally Postmenopausal Women (P06089)
Study Details
Study Description
Brief Summary
Tibolone has been registered for treatment of menopausal symptoms. It is, however, not known what the effects are of tibolone in postmenopausal women diagnosed with sexual dysfunction. This is important because there is currently no approved treatment of libido problems in postmenopausal women. Therefore, the primary aim of this study was to compare the effects of tibolone with an estrogen/progestogen skin patch in postmenopausal women diagnosed sexual dysfunction.

Outcome Measures
Primary Outcome Measures
- Compare the effect of tibolone (2.5 mg) to transdermal E2/NETA (50/140 mcg) on the vaginal bleeding and spotting rate in healthy postmenopausal women with sexual dysfunction. [Week 13-24 of the in treatment period]
- Compare the effect of tibolone to E2/NETA on sexual functioning in healthy postmenopausal women with sexual dysfunction. [Week 8-12 and Week 20-24 of the in-treatment period.]
Secondary Outcome Measures
- Compare the effects of tibolone to E2/NETA on the frequency of satisfactory sexual events, the frequency of sexual fantasies and subjective arousal, scores on the FSFI, FSDS, WHQ and endocrine parameters [Week 8-12 and Week 20-24 of the in-treatment period]
