WebAbstract. Objectives: Clearance of biologics is mediated by two routes: non-specific (linear) protein catabolism and target-mediated (saturable) endocytosis. The hallmark of such target-mediated drug disposition (TMDD) is non-linear clearance, wherein drug clearance and resulting exposure is concentration-dependent.
