An exploratory study to assess the distribution of 111In-ABY-002 tracer uptake for SPECT imaging in subjects with metastatic HER2-positive breast cancer

Conditions
Female subjects having metastatic breast cancer with verified HER2 positive status (DAKO's HerceptTest) in the original primary tumor or one of the current metastases.

Inclusion Criteria

a) Female subjects > 18 years of age
b) Diagnosis of breast cancer
c) HER2-positive diagnosis of the primary tumor or one of the current metastases based on DAKO’s HercepTest, IHC 3+ expression status, or IHC 2+ and HER2 gene amplified according to FISH
d) Volumetrically quantifiable tumor lesions on CT with at least one lesion > 1.0 cm in greatest diameter (quantification) outside the liver.
e) ECOG performance status of = 2.
f) Life expectancy of at least 12 weeks

Primary Outcome Measures
NameTimeMethod
Main Objective: To assess the distribution of 111In-ABY-002 tracer uptake in normal organs and tumor lesions that are detectable with CT, with emphasis on identifying possible heterogeneity in uptake between and within individual metastatic lesions.;Secondary Objective: To assess the safety and tolerability of a single intravenous administration of 111In-ABY-002 in subjects with documented HER2-positive breast cancer,<br>To investigate whole body dosimetry of 111In-ABY-002,<br>To use the kinetics of radionucleide concentration in blood to estimate the absorbed dose in boone marrow.;Primary end point(s): <br>Comparative image analysis of 111In-ABY-002 SPECT images and CT images; <br>-tracer uptake coinciding with normal organ boundaries<br>-tracer uptake coinciding with metastatic lesions visible on CT<br>-focal tracer uptake in regions without pathological findings on CT <br>
