A B7 homolog 3–directed antibody-drug conjugate, demonstrated an overall response rate of 48.2%, with a median duration of response of 5.3 months, and a median progression-free survival of 4.9 months. The 9-month overall survival estimate was 59.1%. This represents another ADC with promising activity, although interstitial lung disease remains a concern, occurring in approximately 12% of patients.
