Abstract

Antibody–drug conjugates (ADC) have emerged as one of the pillars of clinical disease management in oncology. The biggest hurdle to widespread development and application of ADCs has been a narrow therapeutic index. Advances in antibody technologies and formats as well as novel linker and payload chemistries have begun to facilitate structural improvements to ADCs. However, the interplay of structural characteristics with physiologic and pharmacologic factors determining therapeutic success has garnered less attention. This review elaborates on the pharmacology of ADCs, the pathophysiology of cancerous tissues, and the reciprocal consequences on ADC properties and functions. While most currently approved ADCs utilize either microtubule inhibition or DNA damage as primary mechanisms of action, we present arguments to expand this repertoire and highlight the need for payload mechanisms that exploit disease-specific vulnerabilities. We promote the idea that the choice of antibody format, targeting antigen, linker properties, and payload of an ADC should be deliberately fit for purpose by taking the pathophysiology of disease and the specific pharmacology of the drug entity into account, thus allowing a higher probability of clinical success.

  • The histological architecture of mCRPC-characterized by dense stroma, low vascularity, and high between-tumor heterogeneity-has limited ADC penetration and distribution within tumor tissue.

    “In particular, the histological architecture of mCRPC—characterized by dense stroma, low vascularity, and high between-tumor heterogeneity—has limited ADC penetration and distribution within tumor tissue219–222.”

    From The evolving landscape of antibody-drug conjugates (ADCs) for treatment of prostate cancer (2025) · cites this paper as [219]

    The ‘Active and passive targeting’ section says that solid-tumor histopathology can hinder ADC access to cancer cells, and ‘The use of advanced preclinical cancer models’ discusses stromal barriers to penetration and distribution. The paper does not establish that mCRPC specifically has dense stroma, low vascularity, or high between-tumor heterogeneity, or that those features have limited ADC distribution in mCRPC.

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.
