Uterine Fibroids

Estimated Market Size

The National Uterine Fibroids Foundation estimates that as many as 80% of all women in the United States have uterine fibroids, and one in four of these women have symptoms severe enough to require treatment.

  • 700,000 women in the seven major market countries have symptoms severe enough to require surgery or radical treatment.
  • Average age at presentation is 39 while average age at menopause is 49. Treatment for the 10 year period would preserve the uterus until menopause, when fibroids typically resolve spontaneously.

Current Standard of Care

  • Hormone therapy
    • Oral contraceptives and progestins
    • Androgens
  • Gonadotropin releasing hormone agonists, (GnRH agonists), for example, Lupron® (leuprolide acetate). Chronic administration of GnRH agonists reduces the number of GnRH receptors and thereby blocks the action of GnRH in stimulating the pituitary to secrete FSH and LH.
    • GnRH agonists tend to promote bone loss after six months of use
    • Upon cessation of treatment, fibroids typically regenerate rapidly.
  • Uterine artery embolization
  • Myomectomy
  • Hysterectomy
