Source: FDA Label • VANDA PHARMS INC • Atypical Antipsychotic

How FANAPT Works

While the precise mechanism of action is unknown, the efficacy of iloperidone is thought to be mediated through the antagonism of dopamine type 2 (D2) and serotonin type 2 (5-HT2) receptors. The medication also forms an active metabolite called P88, which possesses a receptor binding profile similar to the parent drug. By blocking these specific receptors in the brain, the drug helps manage the symptoms associated with schizophrenia and bipolar I disorder.

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
