Description
PRIMARY OBJECTIVES: I. Determine the dose of pre-administered cold antibody that optimizes image quality of 64Cu-DOTA-trastuzumab PET without increasing the radiation dose to the heart in women with metastatic HER2 positive breast cancer. II. Determine whether tumor uptake on 64Cu-DOTA-trastuzumab P...
PRIMARY OBJECTIVES: I. Determine the dose of pre-administered cold antibody that optimizes image quality of 64Cu-DOTA-trastuzumab PET without increasing the radiation dose to the heart in women with metastatic HER2 positive breast cancer. II. Determine whether tumor uptake on 64Cu-DOTA-trastuzumab PET correlates with tumor expression of HER2 in women with metastatic disease. III. Perform an exploratory analysis of the relationship between uptake on 64Cu-DOTA-trastuzumab PET, HER2 overexpression, and inactivation of the PI3K/Akt pathway. OUTLINE: This is a part one dose-determining study followed by a part two study. PART ONE: Patients are randomized to 1 of 3 dose levels. Patients undergo a PET scan 24-48 hours after injection of 64 Cu-DOTA-trastuzumab. PART TWO: Patients undergo a PET scan 24-48 hours after injection of 64 Cu-DOTA-trastuzumab at the optimal dose as determined in part one of the study.
