Abstract

Insights

Antibody-drug conjugates (ADCs) targeting nectin-4, Trop-2, and HER-2 are advancing urothelial carcinoma treatment. Enfortumab vedotin and sacituzumab govitecan show promise, with HER-2 ADCs under investigation.

Area of Science:

  • Oncology
  • Pharmacology

Background:

  • Antibody-drug conjugates (ADCs) are increasingly vital in treating various cancers, including urothelial carcinoma.
  • Several ADCs targeting specific antigens are under clinical investigation for urothelial carcinoma.

Purpose of the Study:

  • To review recent clinical investigations of ADCs targeting nectin-4, Trop-2, HER-2, and other antigens in urothelial carcinoma.
  • To summarize efficacy, toxicity, resistance mechanisms, and preclinical data for these ADCs.

Main Methods:

  • Literature review of clinical trials and preclinical studies on ADCs in urothelial carcinoma.
  • Analysis of efficacy and toxicity data for ADCs alone and in combination with immunotherapy.

Main Results:

  • Enfortumab vedotin and sacituzumab govitecan are effective in unselected urothelial carcinoma patients.
  • HER-2 ADCs show promise but are limited to patients with high HER-2 expression/amplification.
  • Combination therapies, particularly with immune checkpoint inhibitors, are under active investigation.

Conclusions:

  • Enfortumab vedotin plus pembrolizumab is supported as first-line therapy for metastatic/unresectable locally advanced urothelial carcinoma.
  • Sacituzumab govitecan serves as a later-line option.
  • HER-2 targeted ADC therapy is promising and warrants further investigation.
