Antibody-drug conjugates as targeted therapy for treating gynecologic cancers: update 2025

Abstract

Purpose of review Provide the most up-to-date information on the dynamic landscape of antibody-drug conjugates (ADCs) in gynecologic cancers. We discuss the latest research that supports the approved ADCs and outline the ongoing trials and preliminary results that may lead to ADC approvals in the future. Current gaps in knowledge and areas for future research are discussed. Recent findings ADCs are rapidly changing the landscape of gynecologic cancer care. Three ADCs are currently FDA approved and used routinely in clinical practice, with many more currently in clinical development. The most common ADC target is folate receptor alpha of which there are 8 different folate receptor targeting ADCs in development. Other targets under investigation include trophoblast cell surface antigen-2 (Trop-2), claudin-6 (CLDN6), cadherin-6 (CDH6), nectin-4, HER-2 and B7-H4. ADCs can cause new and unique adverse effects, including ocular toxicities and interstitial lung disease. Summary ADCs offer the opportunity for a more effective and personalized treatment approach for gynecologic cancer patients. Side effects must be closely monitored, and preventive measures must be followed to maximize benefit and minimize toxicity. A better understanding of the role of target proteins as biomarkers to predict response to ADCs will be critical for successful clinical implementation of ADCs and further research in this area is necessary .
