Details and patient eligibility

About

Primary purpose of the clinical study is to evaluate the safety, biodistribution and radiation dosimetry of [131I]-SGMIB Anti-HER2 VHH1 in healthy volunteers and patients with HER2+ breast cancer.

Secondary purpose of the clinical study is to evaluate the tumor uptake of [131I]-SGMIB Anti-HER2 VHH1 in patients with HER2+ breast cancer.
