Objective:

To report the FDA approval of rusfertide (MIMRYLO) for treating erythrocytosis in adults with polycythemia vera.

Approach:
  • Treatment Overview: Rusfertide is a hepcidin mimetic administered weekly via subcutaneous injection, aimed at regulating iron distribution and red blood cell overproduction.
  • Clinical Trial: The approval was supported by the phase 3 VERIFY trial, a randomized, placebo-controlled study involving 293 patients with uncontrolled hematocrit.
Key Findings:
  • 77% of patients receiving rusfertide plus standard of care achieved a clinical response during weeks 20 to 32.
  • Rusfertide treatment resulted in better hematocrit control and reduced need for phlebotomy compared to placebo.
  • Common adverse reactions included injection-site reactions (56%) and anemia (16%).
Limitations:
  • Warnings include new or worsening thrombocytosis, injection-site reactions, and embryo-fetal toxicity.
