BRISDELLE Boxed Warning

SUICIDAL THOUGHTS AND BEHAVIORS Selective serotonin reuptake inhibitors (SSRIs) increased the risk of suicidal thoughts and behavior in pediatric and young adult patients in short-term trials for the treatment of major depressive disorder and other psychiatric disorders. Because BRISDELLE is an SSRI, closely monitor BRISDELLE-treated patients closely for emergence of suicidal thoughts and behaviors [see Warnings and Precautions ( 5.1 )] .

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
