This disclosure relates to tolerance inducing peptide (TIP) derived from the amino acid reference locus (AARL) within a FVIII replacement product (FVIIIrp) based on the differences between the expression product of a subject's F8 gene (sFVIII) and the FVIIIrp to provide tolerance induction before, during, and/or after a FVIII replacement therapy in a subject suffering from Hemophila A. Methods of deriving, making, and using the TIP are also disclosed. In some embodiments, the TIP is associated with a nanoparticle, e.g., PLGA or PLGA-PEMA nanoparticle.
