Recifercept (TA-46) is a soluble, recombinant fibroblast growth factor receptor 3 ( FGFR3 ) molecule. Recifercept can be used as a decoy/ligand trap to decrease the amount of fibroblast growth factors that can bind to mutant FGFR3 receptors. Recifercept can be used for the research of achondroplasia.
