Antibody Pharmacokinetics and Pharmacodynamics

Abstract

The U.S. Food and Drug administration (FDA) has approved several polyclonal antibody preparations and at least 18 monoclonal antibody preparations (antibodies, antibody fragments, antibody fusion proteins, etc.). These drugs, which may be considered as a diverse group of therapeutic proteins, are associated with several interesting pharmacokinetic characteristics. Saturable binding with target antigen may influence antibody disposition, potentially leading to nonlinear distribution and elimination. Independent of antigen interaction, concentration-dependent elimination may be expected for IgG antibodies, due to the influence of the Brambell receptor, FcRn, which protects IgG from catabolism. Antibody administration may induce the development of an endogenous antibody response, which may alter the pharmacokinetics of the therapeutic antibody. Additionally, the pharmacodynamics of antibodies are also complex; these drugs may be used for a wide array of therapeutic applications, and effects may be achieved by a variety of mechanisms. This article provides an overview of many of the complexities associated with antibody pharmacokinetics and pharmacodynamics.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Elimination of mAbs through the kidney is considered insignificant, since typical mAb molecular weight (150 kDa) is higher than the glomerular filtration threshold (~55 kDa).

    “Elimination of mAbs through the kidney is considered insignificant, since typical mAb molecular weight (150 kDa) is higher than the glomerular filtration threshold (∼55 kDa).23”
  • At steady state, mAbs generally exhibit a low volume of distribution of 3-8 L, reflecting their confined distribution to the vascular and interstitial spaces because of their size and polarity.

    “At steady state, mAbs generally exhibit a low volume of distribution of 3–8 L (Table 3), reflecting their confined distribution to the vascular and interstitial spaces because of their size and polarity.23”
  • Nonspecific clearance is considered dose-independent since most therapeutic antibodies at clinically relevant dose levels would fall far below the circulating endogenous IgG levels of ~10 g/ml.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
