Participants recorded rescue analgesic use for endometriosis-associated pain daily and DYS (pain during menstruation ) and its impact on daily activities each day of their period in an electronic diary (e-Diary). DYS was measured by the 4-point Endometriosis Daily Pain Impact Diary according to the following: * 0: No discomfort * 1: Mild discomfort but I was easily able to do the things I usually do * 2: Moderate discomfort or pain that made it difficult to do some of the things I usually do * 3: Severe pain that made it difficult to do the things I usually do. Pain scores and analgesic use were averaged over 35 days prior to each visit. Response was defined as a reduction of -0.92 or more from baseline in DYS as well as no increase in rescue analgesic use for endometriosis-associated pain (defined as a \< 15% increase in average rescue analgesic pill count and no additional analgesic).
Participants recorded rescue analgesic medication for endometriosis-associated pain and assessed NMPP and its impact on their daily activities each day in an e-Diary was measured by the 4-point Endometriosis Daily Pain Impact Diary according to the following: * 0: No discomfort * 1: Mild discomfort but I was easily able to do the things I usually do * 2: Moderate discomfort or pain that made it difficult to do some of the things I usually do * 3: Severe pain that made it difficult to do the things I usually do. Pain scores and analgesic use were averaged over the 35 days prior to each visit. Response was defined as a reduction of -0.55 or greater from baseline for NMPP as well as no increase in rescue analgesic use for endometriosis-associated pain (defined as a \< 15% increase in average pill count of rescue analgesics and no additional analgesics).
Percentage of responders, defined as participants who met the following conditions: * Menstrual blood loss (MBL) volume \< 80 mL during the Final Month (the last 28 days prior to and including the last dose date), and * ≥ 50% reduction in MBL volume from Baseline to the Final Month. Participants who prematurely discontinued study drug due to "lack of efficacy," "requires surgery or invasive intervention for treatment of uterine fibroids," or "adverse events" were considered non-responders regardless of whether she meets the two aforementioned responder criteria or not.

Estradiol/Norethindrone is an investigational small molecule being developed for endometriosis and uterine fibroids. It is a combination of two hormones, estradiol and norethindrone, and is being studied in premenopausal women. The drug is in Phase 3 clinical development and is not yet approved by the FDA.
Estradiol/Norethindrone is being developed by AbbVie Inc. (NYSE: ABBV). The company is conducting Phase 3 clinical trials to evaluate the drug's safety and efficacy in treating endometriosis and uterine fibroids.
Estradiol/Norethindrone is in Phase 3 clinical development. It is an investigational drug and has not been approved by regulatory authorities. The drug is being studied for the treatment of endometriosis and uterine fibroids in premenopausal women.
Estradiol/Norethindrone has been studied in two completed Phase 3 trials. NCT02925494 evaluated the drug in 433 women with uterine fibroids and heavy menstrual bleeding, while NCT03213457 assessed it in 681 women with moderate to severe endometriosis-associated pain. Both trials were conducted in the United States, Canada, and Puerto Rico.
Estradiol/Norethindrone combines two hormones: estradiol, an estrogen, and norethindrone, a progestin. This combination is designed to regulate the menstrual cycle and reduce symptoms associated with endometriosis and uterine fibroids, such as heavy bleeding and pelvic pain.
