AKYNZEO (netupitant)

Serotonin 3 Receptor Antagonists Trial Activity: Declining
Oncology Approved 2014-10-10

Akynzeo is a fixed-dose combination medication (netupitant/palonosetron) indicated for use with dexamethasone in adults for the prevention of acute and delayed nausea and vomiting associated with initial and repeat courses of cancer chemotherapy. The oral capsules are indicated for chemotherapy regimens including, but not limited to, highly emetogenic chemotherapy (HEC). The injectable formulations (containing fosnetupitant/palonosetron) are specifically indicated for HEC, though they have not been studied for use with anthracycline plus cyclophosphamide regimens.

How AKYNZEO Works

Akynzeo targets two distinct signaling pathways involved in chemotherapy-induced nausea and vomiting (CINV). Palonosetron is a 5-HT3 receptor antagonist that prevents nausea and vomiting during the acute phase by blocking serotonin receptors on vagal afferents. Netupitant (or its prodrug fosnetupitant) is a selective NK-1 receptor antagonist that inhibits substance P signaling; according to the FDA indication, netupitant contributes to the prevention of nausea and vomiting in both the acute and delayed phases following chemotherapy.

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
