Clinical Data In the primary endpoint analysis, 87.7% of women achieved the responder criteria defined as a menstrual blood loss volume of less than 80 mL and a 50% or greater reduction from baseline in menstrual blood loss volume during the last 35 days of treatment measured using the alkaline hematin method. The one-year primary endpoint result in the LIBERTY open-label extension study demonstrated durability of the response observed in LIBERTY 1 and 2. In addition, women experienced, on average, an 89.9% reduction in menstrual blood loss from baseline at one year.
Changes in bone mineral density through one year, as assessed by dual energy x-ray absorptiometry (DXA) every three months, were consistent with those in LIBERTY 1 and 2. The incidence of adverse events over one year was consistent with that observed in LIBERTY 1 and 2, with no new safety signals observed. Adverse events reported in more than 10% of women treated with relugolix combination therapy for one year and more frequent than those reported in the placebo group after 6 months included only hot flash. There were no pregnancies reported in the relugolix combination therapy group.
