Abstract

Bispecific antibodies are on the cusp of coming of age as therapeutics more than half a century after they were first described. Two bispecific antibodies, catumaxomab (Removab(®), anti-EpCAM×anti-CD3) and blinatumomab (Blincyto(®), anti-CD19×anti-CD3) are approved for therapy, and >30 additional bispecific antibodies are currently in clinical development. Many of these investigational bispecific antibody drugs are designed to retarget T cells to kill tumor cells, whereas most others are intended to interact with two different disease mediators such as cell surface receptors, soluble ligands and other proteins. The modular architecture of antibodies has been exploited to create more than 60 different bispecific antibody formats. These formats vary in many ways including their molecular weight, number of antigen-binding sites, spatial relationship between different binding sites, valency for each antigen, ability to support secondary immune functions and pharmacokinetic half-life. These diverse formats provide great opportunity to tailor the design of bispecific antibodies to match the proposed mechanisms of action and the intended clinical application.

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.
