Abstract

A majority of human therapeutic antibody candidates show pharmacokinetic properties suitable for clinical use, but an unexpectedly fast antibody clearance is sometimes observed that may limit the clinical utility. Pharmacokinetic data in cynomolgus monkeys collected for a panel of 52 antibodies showed broad distribution of target-independent clearance values (2.4-61.3 mL/day/kg), with 15 (29%) having clearance > 10 mL/day/kg. Alteration in the interaction with the recycling FcRn receptor did not account for the faster than expected clearance observed for the antibodies; off-target binding was presumed to account for the fast clearance. We developed an assay based on ELISA detection of non-specific binding to baculovirus particles that can identify antibodies having increased risk for fast clearance. This assay can be used during lead generation or optimization to identify antibodies with increased risk of having fast clearance in both humans and cynomolgus monkeys, and thus increase the likelihood of obtaining a suitable drug candidate.

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.
