Abstract: The present disclosure provides a method of reversing ticagrelor-associated bleeding in a patient by administering an antibody or fragment thereof that binds to ticagrelor.
Abstract: The present inventors succeeded in improving the antibody constant region to have increased stability under acid conditions, reduced heterogeneity originated from disulfide bonds in the hinge region, reduced heterogeneity originated from the H chain C terminus, and increased stability at high concentrations as well as in discovering novel constant region sequences having reduced Fc? receptor-binding, while minimizing the generation of novel T-cell epitope peptides. As a result, the present inventors successfully discovered antibody constant regions with improved physicochemical properties (stability and homogeneity), immunogenicity, safety, and pharmacokinetics.

Abstract: A pharmaceutical composition comprises a GPCR agonist fusion protein in which a GPCR agonist peptide is covalently coupled to albumin via a linker in a manner that is resistant to a retro-Michael addition. Advantageously, compositions presented herein avoid decoupling of the agonist form the albumin while retaining the agonist in a steric relationship to the albumin that allows for effective binding and activation of the GPCR while also enabling gp60-mediated transcytosis and FcRn-mediated albumin recycling. These properties enable ultra-low dosages for the GPCR agonist fusion protein to give a therapeutic effect while substantially reducing or even entirely avoiding adverse effects otherwise commonly associated with unbound agonists. Moreover, these properties also enable transport of the GPCR agonist fusion protein across the blood brain barrier and therefore allow treatment of neural disorders.
