Study Endpoints

Primary Endpoints

Endometrial Hyperplasia Based on Histological Assessment of Endometrial Biopsies
Week 52

The endometrial hyperplasia rate was calculated based on the number of patients with endometrial hyperplasia/endometrial carcinoma divided by the total number of subjects with interpretable biopsies at Week 52.

Clinical symptoms
after 12 months
Relief of vaginal symptoms
over 12 months of treatment
Safety: Long-term effect on the endometrium assessed through evaluation of endometrial biopsies. AEs, clinical laboratory data and serum hormone levels
Area under the curve (AUC(0-t)), maximal concentration (Cmax) of estradiol after baseline correction
from dosing to day 4

Frequently asked questions about estradiol

What is estradiol used for in menopause?

Estradiol is a small molecule used to treat symptoms of menopause, specifically postmenopausal vaginal atrophy. It is being developed by Novo Nordisk A/S as a low-dose vaginal tablet. The drug is currently in Phase 3 clinical development for this indication.

How does estradiol work?

Estradiol is a form of estrogen, a female sex hormone. It works by replacing the estrogen that decreases during menopause, which helps relieve symptoms such as vaginal atrophy. The drug is administered as a vaginal tablet to deliver the hormone locally.

Who makes estradiol?

Estradiol is being developed by Novo Nordisk A/S, a pharmaceutical company listed on the stock exchange under the ticker NVO. The company is conducting clinical trials to evaluate the drug for the treatment of postmenopausal vaginal atrophy.

What phase is estradiol in?

Estradiol is in Phase 3 clinical development. It has completed six trials, including two Phase 3 studies, with a total enrollment of 1,105 participants. The drug is investigational and has not yet been approved by regulatory authorities.

What clinical trials is estradiol in?

Estradiol has been studied in several clinical trials, including NCT00108849 and NCT00431132, both Phase 3 studies for postmenopausal vaginal atrophy. Other trials include NCT01085877 and NCT01486979, which are Phase 1 studies. All trials have been completed.

Is estradiol the same as Vagifem?

Yes, estradiol is the active ingredient in Vagifem, a vaginal tablet used to treat postmenopausal vaginal atrophy. Clinical trials such as NCT00108849 and NCT00431132 specifically evaluated low doses of Vagifem in postmenopausal women.
