PET Imaging With Cu-64 Labeled Trastuzumab in HER2+ Metastatic Breast Cancer

Completed · Phase 1

Conditions studied: Breast Cancer

In brief

The purpose of this study is to learn more about how a new study agent works inside the body. The study agent is a protein called 64Cu-trastuzumab. This is a radioactive tracer that was developed at MSKCC to target HER2 protein on cancer cells. A radioactive tracer is a small amount of radioactive dye that follows something else that is not radioactive In this study the study agent, 64Cu-trastuzumab, is the tracer and what's being followed is trastuzumab (Herceptin™). By giving you this tracer after you have treatment with trastuzumab (Herceptin™), we will be able to use PET scans to show us which parts of your body and tumor sites the Herceptin goes to. This will help us to understand better how Herceptin works in the body to fight cancer.

You may qualify if…

• Registered patient at MSKCC
• Age ≥18 years
• Patients with HER2+ metastatic breast cancer (either 3+ by immunohistochemistry or with evidence of gene amplification (>2.0) by fluorescence in situ hybridization (FISH))
