Clinical Trial Summary

This is an open-label single photon emission tomography/computed tomography (SPECT/CT) study to investigate the imaging performance of 99mTc-MIRC213 in breast cancer patients. A single dose of 11.1-14.8Mega-Becquerel (MBq) per kilogram body weight 99mTc-MIRC213 will be injected intravenously. Visual and semiquantitative method will be used to assess the SPECT/CT images.


Clinical Trial Description

99mTc-MIRC213 is an nano affibody probe targeting HER2. The investigators will determine the use of 99mTc-MIRC213 SPECT/CT in the detection of HER2- positive breast cancer, and to compare its diagnostic value with routine immunohistochemistry (IHC) pathological staining. HER2 imaging, specifically to HER2 receptor expressed on malignant breast cancer cell surface, might help for targeted therapy with monoclonal antibody such as trastuzumab in breast cancer, and may improve the treatment strategy of breast cancer. The investigator will determine the use of 99mTc-MIRC213 SPECT/CT in stratifying breast cancer. ;
