a study of tranexamic acid (xp12b) in women with heavy menstrual bleeding

Conditions: Menorrhagia

Summary: this was a multicenter, open-label extension study for subjects completing either of 2 pivotal efficacy studies (nct00401193 or nct00386308). the study consisted of a treatment phase of 9 menstrual periods to assess the safety of tranexamic acid at an oral dose of 1.3 g administered 3 times per day for up to 5 days (maximum of 15 doses) during menstruation. after the last treatment period, a follow-up phone call occurred approximately 30 days (range 25 to 35 days) after the last dose of study drug.
