First seen Jan 04, 2026 · Last updated May 16, 2026 · Updated 23 times

Summary

This study enrolls 400 adults with advanced breast, lung, stomach, or bladder cancer who are receiving antibody-drug conjugates (ADCs), a type of targeted therapy. Researchers will compare tumor samples taken before treatment and after the cancer progresses to identify genetic or molecular changes linked to drug resistance. The goal is to better predict which patients will benefit from ADCs and why resistance develops.
