Current Clinical Investigations in Myelofibrosis.

The US Food and Drug Administration (FDA) approval of Janus kinase 2 inhibitors, ruxolitinib and fedratinib for the treatment of intermediate-2 or high-risk primary or secondary myelofibrosis (MF) has revolutionized the management of MF. Nevertheless, these drugs do not reliably alter the natural history of disease. Burgeoning understanding of the molecular pathogenesis and the bone marrow microenvironment in MF has galvanized the development of targeted therapeutics. This review provides insight into the novel therapies under clinical evaluation.
