An Investigational Scan (64Cu-DOTA-Trastuzumab PET/MRI) in Imaging Patients With HER2+ Breast Cancer With Brain Metastasis
Pilot Study to Evaluate 64Cu-DOTA-Trastuzumab Imaging in Patients With HER2+ Breast Cancer With Brain Metastatsis Treated With Fam-Trastuzumab Deruxtecan
City of Hope Medical Center
10 participants

INTERVENTIONAL
Conditions
Summary
This clinical trial examines an investigational scan (64Cu-DOTA-trastuzumab positron emission tomography \[PET\]/magnetic resonance imaging \[MRI\]) in imaging patients with HER2+ breast cancer that has spread to the brain (brain metastasis). Diagnostic procedures, such as 64Cu-DOTA-trastuzumab PET/MRI, may help find HER2+ breast cancer that has spread to the brain and determine whether cancer in the brain takes up trastuzumab, which may predict for response to trastuzumab deruxtecan (the standard of care chemotherapy).
