Window of Opportunity Assessment of [Fam-]Trastuzumab DERuxtecan-nxki (T-DXd) Brain Tumor Penetration and Efficacy (WOnDER-BT)
Memorial Sloan Kettering Cancer Center
Summary
The purpose of this study is to find out how much tratuzumab deruxtecan (T-DXd) can penetrate the tumor when injected into the body, and whether T-DXd may be an effective treatment for brain cancers that express the HER2 protein.
