How XADAGO Works

XADAGO acts as an inhibitor of the enzyme monoamine oxidase B (MAO-B). By blocking the activity of this enzyme, the drug prevents the catabolism, or breakdown, of dopamine. This inhibition is thought to increase dopamine levels and subsequent dopaminergic activity within the brain to exert its therapeutic effects.

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
