Pelvic pain is the main clinical manifestation associated with endometriosis, a disorder caused by endometrial tissues growing outside the uterus. Pain relievers, hormonal contraceptives, aromatase inhibitors, androgenic agents, and gonadotropin-releasing hormone (Gn-RH) agonists are currently used to manage endometriosis-associated pelvic pain. However, more-efficacious and more easily administered medical options remain a high unmet need. The launches of second-generation, orally administered Gn-RH antagonists will significantly expand the endometriosis therapeutic market by 2026.

Questions Answered:

  • Endometriosis usually affects women of reproductive age. How large are the diagnosed prevalent endometriosis populations in the United States and EU5 (France, Germany, Italy, Spain, and the United Kingdom)? What percentage of diagnosed endometriosis patients received drug treatment in 2016? How will the drug-treated rate change in 2026?
  • We expect that by 2024, three Gn-RH antagonists will be launched. What clinical role will second-generation, oral Gn-RH antagonist therapies play in the management of endometriosis? What are clinical advantages of Gn-RH antagonists compared with Gn-RH agonists?
  • AbbVie’s elagolix is the most advanced oral Gn-RH antagonist in development. How will elagolix be differentiated from other emerging Gn-RH antagonists—relugolix and OBE-2109 in the endometriosis therapeutic market?Which emerging Gn-RH antagonists will enjoy the greatest clinical and commercial success by 2026?
