It is not known if Idhifa is safe or effective in children.

Idhifa is approved to be used with the RealTime IDH2 Assay, a diagnostic that detects specific mutations in the IDH2 gene in patients with AML. IDH2 gene mutations may lead to immature blood cells becoming cancerous and dividing uncontrollably, causing AML.
