Ruxolitinib: evolution or revolution in treatment of patients with polycythemia vera?

Abstract

Current treatments for polycythemia vera have remained unchanged for decades with phlebotomy, hydroxycarbamide (also named hydroxyurea) and to a lesser extent interferon being the cornerstones in our therapeutic armamentarium. However, some patients do not respond to, or indeed experience significant side effects to, these current agents and development of alternative therapeutic options is required. Ruxolitinib, a potent JAK1/2 inhibitor, initially approved for myelofibrosis, was recently approved for patients with polycythemia vera refractory or intolerant to hydroxycarbamide. In this article, we review the currently available efficacy and safety data.
