A Study of Fedratinib With IDH Inhibition in Advanced-Phase, IDH-Mutated Ph-Negative Myeloproliferative Neoplasms

Doctors leading this study hope to learn about the safety of combining fedratinib (a type of drug called a "JAK inhibitor" whichblocks the activity of janus kinase enzymes in your body) with anti-cancer drugs ivosidenib and enasidenib in participants who have rare blood cancers that show Isocitrate dehydrogenase (IDH) mutations (a type of genetic mutation). Your participation in this research will last about 24 months. The purpose of this research is to gather information on the safety and effectiveness of fedratinib in combination with ivosidenib or enasidenib. While all three drugs are FDA-approved for various conditions, the US Food and Drug Administration (FDA) has not approved the combination of these drugs for the treatment of IDH-mutated blood cancers (known as myeloproliferative neoplasms), and therefore these drugs can only be given in a research study.
