Ruxolitinib, formerly known as INCB018424 or INC424, is a potent and selective oral inhibitor of Janus kinase (JAK) 1 and JAK2. Ruxolitinib has been approved for the treatment of myelofibrosis (MF) by the US Food and Drug Administration (FDA) in 2011 and by the European Medicines Agency (EMA) in 2012, followed by the approval for the treatment of hydroxyurea (HU)-resistant or -intolerant polycythemia vera (PV) in 2014. Both MF and PV are myeloproliferative neoplasms (MPNs) which are characterized by the aberrant activation of the JAK–STAT pathway. Clinically, MF features bone marrow fibrosis, splenomegaly, abnormal blood counts, and poor quality-of-life through associated symptoms. PV is characterized by the overproduction of primarily red blood cells (RBC), risk of thrombotic complications, and development of secondary MF. Ruxolitinib treatment results in a meaningful reduction in spleen size and symptom burden in the majority of MF patients and may also have a favorable effect on survival. In PV, ruxolitinib effectively controls the hematocrit and reduces splenomegaly. Since recently, ruxolitinib is also under investigation for the treatment of graft-versus-host disease (GvHD) after allogeneic hematopoietic stem cell transplantation (HSCT). Toxicities of ruxolitinib include myelosuppression, which results in dose-limiting thrombocytopenia and anemia, and viral reactivations. The metabolization of ruxolitinib through CYP3A4 needs to be considered particularly if co-administered with potent CYP3A4 inhibitors. Several further JAK inhibitors are currently under investigation for MPNs or other immuno-inflammatory diseases.
