NCT ID NCT04561362

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tests a new drug called BT8009, alone or with another drug (pembrolizumab), in people with advanced solid tumors like bladder, breast, lung, or ovarian cancer. The drug targets a protein called Nectin-4 found on some cancer cells. The trial aims to find safe doses and see if the drug shrinks tumors. It is still early, so the main goals are safety and understanding how the drug works in the body.
