Higel, Fabian; Seidl, Andreas; Sörgel, Fritz; Friess, Wolfgang (2016): N-glycosylation heterogeneity and the influence on structure, function and pharmacokinetics of monoclonal antibodies and Fc fusion proteins. In: European Journal of Pharmaceutics and Biopharmaceutics, Vol. 100: pp. 94-100

Monoclonal antibody and Fc fusion protein drugs are complex heterogeneous mixtures of numerous different protein variants and modifications. N-glycosylation as one of the most complex post translational modification influences the structural characteristics of the antibodies Fc part thereby potentially modulating effector function and pharmacokinetics. Several investigations on the relationship between N-glycosylation and pharmacokinetics have been published. However, this structure-function relationship is not fully understood. In this review potential alterations with focus on N-glycosylation of mAbs and Fc fusion proteins and the possible effects on the pharmacokinetics are reviewed and the current understandings of the underlying mechanisms are described.
