Frequently asked questions about Estradiol

What is estradiol used for in vasomotor symptoms?

Estradiol is used to treat vasomotor symptoms, the hot flashes and night sweats associated with menopause. In this program it is being developed as estradiol alone and as a combination of estradiol with drospirenone for postmenopausal women with vasomotor symptoms. It is a small molecule in Phase 3 development.

How does estradiol work?

Estradiol works as an agonist at ESR1, the estrogen receptor alpha. By binding and activating this nuclear receptor, it mimics endogenous estrogen signaling, which helps restore hormonal balance and reduce the vasomotor symptoms that follow the decline in estrogen levels after menopause.

Who is developing estradiol for vasomotor symptoms?

Bayer AG is developing estradiol, including the estradiol and drospirenone combination, for vasomotor symptoms. Bayer trades on the OTC market under the ticker BAYRY. The program is in Phase 3 clinical development.

What phase is estradiol in for vasomotor symptoms?

Estradiol is in Phase 3 development for vasomotor symptoms. It is an investigational therapy and is not approved for this use based on the available program information. The Phase 3 study in this program has been completed.

What clinical trials is estradiol in for vasomotor symptoms?

The Phase 3 trial NCT00356447 evaluated the safety and efficacy of drospirenone and estradiol in postmenopausal Chinese women with vasomotor symptoms. It was a randomized, double-blind, placebo-controlled study that enrolled 249 women aged 45 years and older in China and is now completed.

Is estradiol the same as Angeliq or BAY86-4891?

Yes. Estradiol is also known as E2 0.3mg, and the estradiol and drospirenone combination is known as Angeliq or BAY86-4891. These names refer to the same Bayer program, which pairs estradiol with drospirenone for vasomotor symptoms.
