ROP-ET and BESREMI PASS

One of the clinical studies, ROP-ET, examined the use of ropeginterferon alfa-2b in people with essential thrombocythemia (ET), a disease in which the body produces too many platelets. The trial, a prospective, multicenter, single-arm phase III study, investigated the safety and efficacy of ropeginterferon alfa-2b in ET patients unable to receive available cytoreductive therapies¹.

The other investigation, the BESREMi-PASS study, looked at how the medicine performs in everyday clinical practice among people with polycythemia vera (PV). PV is a rare cancer of the blood-building stem cells in the bone marrow resulting in a chronic increase of red blood cells, white blood cells and platelets.

Solutions for unmet medical need

Both studies provide new insights into how ropeginterferon alfa-2b may help people living with these chronic blood cancers.

Martin Steinhart, CEO of AOP Health, concludes: “AOP Health was founded to address unmet patient needs in rare indications. Our continued investment in research and development is a testament to that commitment, resulting in new findings that we are now proud to share with the scientific community at ASH.”

About Ropeginterferon alfa-2b

Ropeginterferon alfa-2b is the first interferon approved for polycythemia vera, a myelo­proliferative neoplasm (MPN), indicated in the European Union as monotherapy in adults for treatment of polycythaemia vera without symptomatic enlarged spleen.

Ropeginterferon alfa-2b is a long-acting, mono-pegylated proline interferon (ATC L03AB15). It is administered once every 2 weeks initially, or up to every 4 weeks after stabilization of blood values. It is designed to be self-administered subcutaneously with a pre-filled pen.
