Study Endpoints

Primary Endpoints

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.
The primary objective of this trial was to compare changes in the expression of the proliferation marker Ki-67 in malignant breast tissue after treatment with tibolone or placebo.
The primary outcome measure, the proliferation marker Ki-67, was measured at screening (from the screening biopsy) and about 14 days later (from the surgically removed breast tumour tissue)
To show non-inferiority in breast cancer recurrence of tibolone 2.5 mg versus placebo in women with climacteric symptoms who have been surgically treated for primary breast cancer within the last 5 years
At clinical completion
Endometrial biopsy and histological examination
At 1 year and 2 year.
The primary efficacy parameter was reduction in incident new vertebral fractures assessed by spinal radiographs (anterior-posterior and lateral)
3 years

Secondary Endpoints

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
Apoptosis index; estrogen/progesterone/androgen receptors & isoforms; bcl-2, bax; pS2; SOX4; Apolipoprotein D; Angiogenesis parameters; estrogen levels, tibolone and tibolone metabolites.
Outcome parameters were measured during the trial as samples were received and at the end of the clinical phase.
Secondary outcome variables include overall survival, menopausal symptoms, bone mineral density and health-related quality of life.

Frequently asked questions about tibolone

What is tibolone?

Tibolone is a small molecule drug developed by Organon & Co. (ticker OGN). It has been studied in Phase 3 clinical trials for several conditions affecting women, including breast cancer, osteoporosis, sexual dysfunction, and use in postmenopausal women. It is a synthetic steroid that acts on multiple tissues.

What is tibolone used for?

Tibolone has been investigated in Phase 3 trials for osteoporosis in women aged 60 and older, for breast tissue effects in postmenopausal women with breast cancer, for sexual dysfunction in naturally postmenopausal women, and for endometrial effects in postmenopausal women. These studies are completed, and tibolone remains an investigational agent in these programs.

Who makes tibolone?

Tibolone is developed by Organon & Co., which trades under the ticker OGN. Organon sponsored the Phase 3 clinical program evaluating tibolone across breast cancer, osteoporosis, sexual dysfunction, and postmenopausal women indications.

What phase is tibolone in?

Tibolone is in Phase 3 clinical development. Its Phase 3 trials are completed, and no active trials are currently listed. Tibolone is investigational and has not been established as approved for the indications studied in this program.

What clinical trials is tibolone in?

Tibolone has been studied in completed Phase 3 trials including NCT00745108 in postmenopausal women, NCT00725374 in postmenopausal women with breast cancer, NCT00519857 in osteoporosis, and NCT00413764 comparing tibolone with transdermal E2/NETA for sexual function in naturally postmenopausal women. All four trials are completed.

How many patients were enrolled in tibolone trials?

The tibolone Phase 3 program enrolled a total of 4,534 participants across its trials. The largest study, NCT00519857 in osteoporosis, enrolled 4,534 women aged 60 and older. The trials were randomized, double-blind, and placebo-controlled, with some biomarker-selected patient populations.
