Luspatercept (mIgG2a)
Luspatercept (mIgG2a) (RAP-536) is a fusion protein, consisting of a modified extracellular domain of human ActRIIB linked to the murine IgG2a Fc domain. Luspatercept (mIgG2a) inhibits Smad2/3 signaling, promotes differentiation of late-stage erythroid precursors and mitigates ineffective erythropoiesis (IE) in murine β-thalassemia. Luspatercept (mIgG2a) reduces anemia, α-globin aggregates, hemolysis, and disease complications of IE such as iron overload, splenomegaly, and bone defects[1].
