Ropeginterferon alfa-2b was approved for medical use in Europe in 2019 and the United States in 2021.[3][2] In the United Kingdom it costs the NHS about £1,800 for 250 mcg as of 2021.[5] This amount in the United States is about 3,600 USD as of 2022.[6]

Medical uses

In the European Union, ropeginterferon alfa-2b is indicated as monotherapy in adults for the treatment of polycythemia vera without symptomatic splenomegaly.[3] In the United States it is indicated for the treatment of polycythemia vera.[2][4]

Dosage

It is generally started at a dose of 100 mcg every 2 weeks, which may be increased to 500 mcg every 2 weeks based on blood tests.[2]

History

The effectiveness and safety of ropeginterferon alfa-2b were evaluated in a multicenter, single-arm trial that lasted 7.5 years.[4] In this trial, 51 adults with polycythemia vera received ropeginterferon alfa-2b for an average of about five years.[4] The effectiveness of ropeginterferon alfa-2b was assessed by looking at how many participants achieved complete hematological response, which meant that participants had a red blood cell volume of less than 45% without a recent phlebotomy, normal white cell counts and platelet counts, a normal spleen size, and no blood clots.[4] Overall, 61% of participants had a complete hematological response.[4] The U.S. Food and Drug Administration (FDA) granted the application for Ropeginterferon_alfa-2b orphan drug designation and granted the approval of Besremi to PharmaEssentia Corporation[4] Ropeginterferon alfa-2b is the first medication approved by the U.S. Food and Drug Administration (FDA) to treat polycythemia vera that people can take regardless of their treatment history, and the first interferon therapy specifically approved for polycythemia vera.[4]
