What is Emavusertib?

Emavusertib is an orally bioavailable reversible inhibitor of IRAK4 kinase. It blocks IRAK4-mediated signaling and NF-kB pathway activation, reducing inflammatory cytokine expression and pro-survival factors. It is studied in relapsed or refractory hematologic malignancies, primary CNS lymphoma, myelodysplastic syndromes, and anemia.
