Frequently asked questions about levonorgestrel/ Microlut

What is Levonorgestrel used for?

Levonorgestrel is a small molecule being studied for contraception, endometriosis, and biological availability. It is developed by Bayer AG. In clinical trials, it has been evaluated as an intravaginal ring for contraception and in a dose-finding study for endometriosis.

Who makes Levonorgestrel?

Levonorgestrel is developed by Bayer AG, a company traded under the ticker BAYRY. Bayer has conducted multiple clinical trials with Levonorgestrel, including Phase 3 studies for contraception and a Phase 2 study for endometriosis.

What phase is Levonorgestrel in?

Levonorgestrel has completed Phase 3 clinical trials for contraception and a Phase 2 trial for endometriosis. It remains an investigational drug in clinical development, as no approval status has been reported for these indications.

What clinical trials is Levonorgestrel in?

Levonorgestrel has been studied in several completed trials. NCT02403401 was a Phase 3 safety and efficacy study of an intravaginal ring with Levonorgestrel for contraception. NCT02203331 was a Phase 2 dose-finding study for endometriosis. NCT03074045 compared a levonorgestrel-releasing system to a combined oral contraceptive.

How does Levonorgestrel work?

Levonorgestrel is a progestin hormone. It works by suppressing ovulation and thickening cervical mucus to prevent sperm penetration, which is its mechanism for contraception. In endometriosis, it may reduce endometrial tissue growth through its progestogenic effects.

Is Levonorgestrel the same as LNG?

Yes, Levonorgestrel is commonly abbreviated as LNG. Clinical trial titles refer to it as LNG, such as in the study of an intravaginal ring with LNG for contraception. It is also known by the code name Bay98-7196 in some research contexts.
