How VEOZAH Works

Fezolinetant acts as a selective neurokinin 3 (NK3) receptor antagonist. It blocks neurokinin B (NKB) binding on kisspeptin/neurokinin B/dynorphin (KNDy) neurons within the hypothalamic thermoregulatory center to modulate neuronal activity and restore body temperature homeostasis. It demonstrates high affinity for the NK3 receptor (Ki: 19.9 to 22.1 nmol/L), with greater than 450-fold selectivity over NK1 and NK2 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
