In Vivo Stability of Therapeutic Proteins

Significant efforts are made to characterize molecular liabilities and degradation of the drug substance (DS) and drug product (DP) during various product life-cycle stages. The in vivo fate of a therapeutic protein is usually only considered in terms of pharmacokinetics (PKs) and pharmacodynamics (PDs). However, the environment in the human body differs substantially from that of the matrix (formulation) of the DP and may impact on the...
