Trial Activity: Declining 2 active trials
First-in-Class Priority Review
Women's Health Approved 2018-07-23

Orilissa helps patients with moderate to severe pain that occurs as a result of endometriosis. It is used to manage these painful symptoms by influencing the body's hormonal signaling. Healthcare providers typically limit how long a patient stays on the medication depending on the specific dose prescribed and any other existing health conditions.

How ORILISSA Works

This medication works by binding to GnRH receptors in the pituitary gland to block natural signaling. This action suppresses the production of luteinizing hormone and follicle-stimulating hormone, which in turn lowers the levels of ovarian hormones like estradiol and progesterone in the bloodstream.

How We Calculate These Metrics

Trial Activity Stage

Measures the current development activity pattern based on trial phases, status, and trends. Important: This measures R&D activity, not commercial lifecycle.

Trial statuses: "Active" means recruiting or ongoing. "Completed" means reached planned endpoint. "Terminated" means stopped early—often due to safety, efficacy, or business reasons.

  • Growth: High proportion of early-phase trials (Phase 1/2), active development
  • Expansion: Significant Phase 3 activity, approaching or pursuing approvals
  • Mature: Substantial Phase 4 post-marketing studies
  • Stable: Mixed phase distribution, steady development
  • Declining: Low active trial ratio, reduced R&D investment
