How REZLIDHIA Works

Olutasidenib is a small-molecule inhibitor of mutated IDH1 enzymes. It specifically inhibits various R132 substitution mutations (including R132H, R132L, R132S, R132G, and R132C) without inhibiting wild-type IDH1 or mutated IDH2 proteins. By blocking these mutant enzymes, the drug reduces the accumulation of the oncometabolite 2-hydroxyglutarate (2-HG), thereby restoring normal cellular differentiation in leukemia cells.

REZLIDHIA Boxed Warning

DIFFERENTIATION SYNDROME Differentiation syndrome, which can be fatal, can occur with REZLIDHIA treatment. Symptoms may include dyspnea, pulmonary infiltrates/pleuropericardial effusion, kidney injury, hypotension, fever, and weight gain. If differentiation syndrome is suspected, withhold REZLIDHIA and initiate treatment with corticosteroids and hemodynamic monitoring until symptom resolution [see Warnings and Precautions ( 5.1 )] .

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
