About
Researchers want to learn if patritumab deruxtecan (MK-1022) can treat certain breast cancers. The breast cancers being studied are HER2 positive unresectable locally advanced or metastatic (the cancer has spread to other parts of the body). The goals of this study are to learn:
- About the safety and how well people tolerate of patritumab deruxtecan
- How many people have the cancer respond (get smaller or go away) to treatment
Full description
The following countries will be participating in the trial: Canada, United Kingdom, Israel, Japan, South Korea, and USA.
