(16) Methods of Reducing or Managing Heavy Menstrual Bleeding Associated with Uterine Fibroids
(17) In one embodiment, the present invention relates to methods for reducing or managing heavy menstrual bleeding (HMB) associated with uterine fibroids in subjects in need of treatment thereof. Heavy menstrual bleeding refers to a subject experiencing greater than 80 mL of blood loss per menstrual cycle (a menstrual cycle is typically 28 days). In contrast, women who do not suffer from heavy menstrual bleeding experience about 30-40 mL of blood loss per menstrual cycle. In one aspect, the methods of the present invention can be used to reduce or manage heavy menstrual bleeding in a subject with uterine fibroids to an amount less than 80 mL of blood loss per cycle. In another aspect, the methods of the present invention can be used to reduce the volume of heavy menstrual bleeding in the subject with uterine fibroids by at least 50% from baseline.
(18) Methods for analyzing menstrual blood loss are known in the art and include, for example, the alkaline hematin method. The alkaline hematin method is based on the quantitation of menstrual blood collected on sanitary products (Hallberg L., Nilsoon L., Determination of Menstrual Blood Loss. Scand. J. Clin. Lab. Invest., 1964; 16:244-248). The method uses a strong alkaline solution to chemically convert the heme from bloodstained sanitary products to alkaline hematin, which is measured colorimetrically. When compared to a subject's serum hemoglobin (Hgb), the volume of blood loss in the menstrual products can be determined.
(19) a. Use of Elagolix or a Pharmaceutically Acceptable Salt Thereof
(20) In one aspect, the methods of the present invention involve reducing or managing heavy menstrual bleeding associated with uterine fibroids in a subject in need of treatment thereof. The methods involve administering to a subject suffering from heavy menstrual bleeding associated with uterine fibroids an effective amount of Elagolix or a pharmaceutically acceptable salt thereof. The effective amount or dose of Elagolix or a pharmaceutically acceptable salt thereof that can be administered to a subject is in the range of 300 to 600 mg.

EXAMPLES
Example 1: Summary of Efficacy and Safety Findings in Completed Phase 2 Studies in Endometriosis Subjects
(197) Efficacy
(198) Six Phase 2 randomized, double-blind, placebo-, and/or active-controlled, parallel-group, multiple dose studies were completed to evaluate elagolix as a treatment for endometriosis associated pain. Efficacy was assessed for dysmenorrhea (DYS), nonmenstrual pelvic pain (NMPP), dyspareunia, and general pelvic pain with a range of instruments.
(199) Additional efficacy assessments included quality of life and the use of analgesics for control of endometriosis pain.
(200) Across these Phase 2 studies, the enrollment criteria were similar and were intended to select premenopausal women aged 18 to 49 years of age with endometriosis confirmed by visual inspection (laparoscopy or laparotomy within 5 to 8 years of screening) who experienced moderate to severe endometriosis-associated pain. Women were included if they had regular menstrual cycles and no significant uterine fibroids or pelvic lesions.
(201) Total daily doses of elagolix ranging from 75 to 250 mg were evaluated across a range of pain instruments measuring DYS, NMPP, or general pelvic pain (including patient global impression of change), during 12 or 24 weeks of treatment.
(202) Collectively, these Phase 2 studies showed that elagolix daily doses of 100 to 250 mg were associated with clinically meaningful reductions in endometriosis-associated pain.
(203) Studies also demonstrated that an elagolix daily dose of 150 mg had comparable effect to subcutaneous depot medroxyprogesterone acetate (DMPA-SC) on DYS and NMPP, while elagolix daily doses of 150 mg and 250 mg had less effect compared with leuprorelin.
(204) Additionally, symptoms of dyspareunia were reduced and women reported improved quality of life assessments. Overall usage of analgesics for pain control also decreased in the elagolix treatment arms.
(205) The effects of elagolix on uterine bleeding were evaluated in the Phase 2 endometriosis program, with an analysis of the percentage of days of bleeding per month according to daily reporting of bleeding in an electronic diary (eDiary). These analyses showed that overall, patients on elagolix experienced fewer days of bleeding per month compared with patients who received placebo; patients on 250 mg QD experienced fewer days of bleeding compared with patients on 150 mg QD. Review of individual menstrual charts from daily eDiary records showed that the majority of elagolix recipients experienced reduced bleeding intensity and often had extended intervals between bleeding episodes,
(206) Some subjects experienced periods of oligomenorrhea with some evidence of irregular bleeding as well, particularly at lower doses of elagolix.
(207) Safety
(208) The safety and tolerability of elagolix in women with endometriosis has been evaluated in 6 completed Phase 2 studies including 708 women who received at least 1 dose of elagolix. Overall, 475 women have received elagolix for at least 12 weeks and 278 women for a period of at least 24 weeks. The majority of women were Caucasian (78.9% to 100%), while approximately 7% were black and approximately 4.5% were Hispanic. The mean age across these six Phase 2 studies was 31 to 33 years (range 18 to 48 years) and mean body mass index (BMI) of 23 to 28 kg/m. Overall, 40% to 70% of women had received prior therapy for the treatment of endometriosis, and hormonal contraceptives were the most common class of drug prescribed for the condition. In addition, the majority were receiving analgesic medications (nonsteroidal anti-inflammatory drugs, opioids, and/or other) prior to study enrollment.
(209) Review of the safety data in the completed Phase 2 studies in women with endometriosis indicates that elagolix was safe and well tolerated for all daily doses (100 to 250 mg) that were evaluated. The incidence of AEs (4.8%) that led to discontinuations was 4.8%, The most common adverse events observed with elagolix in both the 12-week and 24-week analysis sets were headache and nausea with an incidence similar to that observed with DMPA-SC in the 24-week analysis. None of these events were serious and they contributed to less than 1% of study discontinuations.
(210) Effects on Bone Mineral Density (BMD)
(211) Changes in BMD at the lumbar spine and the femur were evaluated over 24 weeks in three Phase 2 endometriosis studies. At the lumbar spine, mean BMD percent reductions from baseline appeared to be dose related: 0.11% to 1.29% at the 150 mg dose and 1.63% to 1.86% at the 250 mg dose. In the largest of these studies a small number of subjects, 2/55 (3.6%) in the 150 mg QD and 5/62 (8.1%) in the 75 mg BID regimens had decreases in BMD of the spine that exceeded 5% (no subject exceeded −8%) at 24 weeks. While a larger effect on BMD is anticipated with a 200 or 300 mg BID regimen compared to that observed with 250 mg QD dosed for 6 months in previous studies, the magnitude of this effect is unknown.
(212) A modest degree of bone loss has been seen in elagolix-treated endometriosis subjects at doses that provide partial estrogen suppression (target dose 150 mg QD).
Example 2
(213) This example is a Phase 2a, multicenter, double-blind, placebo-controlled, randomized trial (N=280) with a 3-month treatment duration evaluating the safety and efficacy of Elagolix administered with or without Activella® in premenopausal women with uterine fibroids.
(214) It evaluates the safety and efficacy of 6 doses of Elagolix (100 mg BID, 200 mg BID, 200 mg BID plus low dose Activella® (a combination of 0.5 mg estradiol and 0.1 mg northindrone acetate), 300 mg BID, 300 mg BID plus 1.0 mg of Estrace and 200 mg cyclical Prometrium (collectively referred to as “EP”), 400 mg QD and 600 QD) versus placebo (PBO) to reduce uterine bleeding associated with uterine fibroids and to reduce fibroid volume and uterine volume in premenopausal women 20 to 49 years of age with heavy menstrual bleeding (HMB; >80 mL blood loss per menstrual cycle). The study involved the following six (6) cohorts:
(215) Cohort 1: Elagolix 200 mg BID or placebo (PBO).
(216) Cohort 2: Elagolix 300 mg BID or placebo.
(217) Cohort 3: Elagolix 200 mg BID plus low dose Activella® (a combination of 0.5 mg estradiol and 0.1 mg norethindrone actate).
(218) Cohort 4: Elagolix 100 mg BID, 400 mg QD or placebo.
(219) Cohort 5: Elagolix 600 mg QD.
(220) Cohort 6: Elagolix 300 mg BID plus estrogen (1.0 mg of estradiol (Estrace®)) and 200 mg progesterone (cyclical Prometrium®)) (EP). Estrace® was given daily with Elagolix (continuously) and Prometrium® was given daily for the last 12 days of each 28 day menstrual cycle (cyclical).
(221) An exemplary administration schedule for Elagolix 300 mg BID alone or with add-back is shown in Table A. Subjects can self-administer drug twice a day (in the morning and in the evening approximately 12 hours apart).

(229) Efficacy
(230) There are a number of efficacy endpoints, but a composite endpoint consisting of two bleeding assessments was used to assess one measure of efficacy. It included the percent of subjects who achieved a menstrual blood loss (MBL) volume of <80 mL at the Final Month (last 28 days of treatment), and also achieved a ≥50% reduction in MBL volume from baseline to the Final Month (last 28 days of treatment) as measured by the Alkaline Hematin (AH) method. Eighty-five percent (85%), 97%, and 30% of subjects achieved the composite bleeding assessment endpoint in the 200 mg BID, 300 mg BID, and placebo groups, respectively (P<0.05 for 200 mg BID versus placebo in cohort 1, and 300 mg BID versus placebo in cohort 2). Eighty-two percent (82%) of subjects in the 200 mg BID+low-dose Activella® (low dose Activella® is a combination of (a combination of 0.5 mg estradiol and 0.1 mg norethindrone acetate) group achieved this composite endpoint. With respect to fibroid and uterine volumes, 63%, 55%, and 29% of subjects achieved a ≥25% reduction in fibroid volume and 50%, 68%, and 9% achieved a ≥25% reduction in uterine volume in the 200 mg BID, 300 mg BID, and placebo groups, respectively. In the 200 mg BID+low dose group, 53% and 42% of subjects achieved a ≥25% reduction in fibroid and uterine volume, respectively.
