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.


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.

Outcome

Type Measure Description Time frame Safety issue
Primary Dosimetric distribution of radiopharmaceuticals Input the data of 5-6 patients into HERMES software, and analyze the dose distribution of radioactive drugs in human body through HERMES software 2 months
Primary Standardized uptake value The semiquantitative analysis will be performed by the same person for all the cases, and the standardized uptake value (SUV) of the tracer in breast tumor will be measured. SUV were obtained by a self-made software and referring to phantom study.If the SUV value cannot be obtained, the COUNTS of target organ/background ratio between the lesion and surrounding tissues shall be used for calculation. 1 year
Secondary Adverse events collection Adverse events within 1 week after the injection and scanning of patients and patients will be followed and assessed 1 year
