Measure
PET Imaging With 89Zr-DFO-Trastuzumab
Patients will receive 5 mCi + 0.5 mCi of 89Zr-DFO-trastuzumab given IV over 5-10 min. Injection of cold trastuzumab will be mixed with 89Zr-DFO-trastuzumab so that total mass is equal to 50 mg \[1\]. In the first ten patients we wish to obtain normal organ dosimetry, pharmacokinetics \& determine optimal imaging time, therefore these patients will undergo imaging at 4 time points post injection, whole body counts \& blood draws. Subsequent patients will receive the antibody \& will only undergo imaging at a single time point (based on the first 10 patients) \& will not have whole body counts or serial bloods for pharmacokinetics. The administration of 89Zr-DFO-trastuzumab to patients undergoing a second study will be identical as for their baseline study. Patients undergoing a second injection will only have one scan that will be performed within 1 day before or 2 days after their optimum imaging time point, determined from their baseline imaging study. 89Zr-DFO-trastuzumab PET imaging

PRIMARY outcome

Timeframe: 2 years

Population: This study is based on a cohort expansion. All data is appropriately reported as there is only one study cohort

Antibody imaging is considered feasible if 70% of the patients are antibody-imaging positive. Antibody imaging will be considered feasible if 7 or more of the 10 patients in the first cohort are antibody-imaging-positive. We will also require that none of these patients experience severe toxicity attributable to the initial antibody.

SECONDARY outcome

Timeframe: Up to 580 hours

Population: This study is based on a cohort expansion. All data is appropriately reported as there is only one study cohort

Samples will be obtained just prior to injection of the 89Zr DFO-trastuzumab tracer this sample will be banked at -80degree C for future testing for Human anti-human antibody/HAHA if altered biodistribution is observed.
