How REXULTI Works

Brexpiprazole is a serotonin-dopamine activity modulator (SDAM). While its precise mechanism is not fully established, its efficacy is thought to be mediated through a combination of partial agonist activity at serotonin 5-HT1A and dopamine D2 receptors, and antagonist activity at serotonin 5-HT2A receptors. It also demonstrates high affinity (antagonist activity) for noradrenergic alpha-1B and alpha-2C receptors. Compared to earlier atypical antipsychotics like aripiprazole, brexpiprazole has lower intrinsic activity at the D2 receptor and higher affinity for 5-HT1A and 5-HT2A receptors.

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
