B7-H4-directed agents, particularly antibody-drug conjugates (ADCs) like puxitatug samrotecan (AZD8205), felmetatug vedotin (SGN-B7H4V), and GSK5733584, have demonstrated early clinical activity with promising response rates in triple-negative breast cancer (TNBC). Combination strategies, such as ADCs with anti-PD-1 or PARP inhibitor therapies, have also shown enhanced tumor regression in preclinical models and are the subject of several ongoing clinical trials. This review highlights the current landscape of B7-H4-targeted agents, their progress in clinical trials, and the potential for combination approaches to improve outcomes in B7-H4-expressing cancers.
