Frequently asked questions about Estradiol/Norethindrone

What is Estradiol used for?

Estradiol is a small molecule being developed by Teva Pharmaceutical Industries Limited for the treatment of dyspareunia, which is pain during intercourse, in women with vulvar and vaginal atrophy. It is also studied in healthy volunteers for pharmacokinetic purposes. The drug is currently in Phase 3 clinical development.

Who makes Estradiol?

Teva Pharmaceutical Industries Limited (NYSE: TEVA) is developing Estradiol. The company is conducting clinical trials to evaluate the drug's safety and efficacy for treating dyspareunia associated with vulvar and vaginal atrophy.

What phase is Estradiol in?

Estradiol is in Phase 3 clinical development. A completed Phase 3 trial (NCT05617820) compared Estradiol vaginal inserts 4 mcg to IMVEXXY (estradiol vaginal inserts 4 mcg) in the treatment of dyspareunia in women with vulvar and vaginal atrophy.

What clinical trials is Estradiol in?

Estradiol has been studied in three clinical trials. Two Phase 1 trials (NCT01157182 and NCT01181726) evaluated Estradiol/Norethindrone Acetate Tablets under fasting and fed conditions in healthy women. A Phase 3 trial (NCT05617820) compared Estradiol vaginal inserts to IMVEXXY in treating dyspareunia.

Is Estradiol FDA approved?

Estradiol is an investigational drug still in clinical development. It has completed Phase 3 trials but has not been reported as FDA approved. The Phase 3 trial compared Estradiol vaginal inserts to IMVEXXY, which is an approved product, but Estradiol itself remains under investigation.

How does Estradiol work?

Estradiol is a form of estrogen, a female sex hormone. In the context of treating dyspareunia, it works by replacing estrogen in vaginal tissue, which helps restore the health of the vaginal lining and reduce pain during intercourse associated with vulvar and vaginal atrophy.
