IDHIFA (enasidenib mesylate)

Genetically Validated Trial Activity: Growth 18 active trials
First-in-Class Orphan Drug Priority Review Fast Track
Oncology Approved 2017-08-01

IDHIFA treats adults with acute myeloid leukemia (AML) that has returned or has not responded to previous therapies. It helps patients whose cancer cells carry a specific mutation in the isocitrate dehydrogenase-2 (IDH2) enzyme. Before starting this medication, patients must undergo a specialized test to confirm they have this specific genetic marker.

How IDHIFA Works

This drug works by blocking the activity of the mutated IDH2 enzyme, which is found in certain types of leukemia cells. By inhibiting this enzyme, the medication lowers levels of a substance called 2-hydroxyglutarate and encourages immature cancer cells to develop into mature, functioning myeloid cells. This process helps reduce the overall number of leukemia blast cells in the blood.

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
