Ab­b­Vie wins an ap­proval in uter­ine fi­broid-as­so­ci­at­ed heavy bleed­ing. Are ri­vals My­ovant and Ob­sE­va far be­hind?

Women ex­pel on av­er­age about 2 to 3 ta­ble­spoons of blood dur­ing their time of the month. But with uter­ine fi­broids, heavy bleed­ing is typ­i­cal — a third of a cup or more.
