Summary:

      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.

          -  Subject with blood parameters within normal ranges

          -  Age: at least 18 years old

        Patients will only be included in the study if they meet all of the following criteria:

          -  Patients who have given informed consent

          -  Patients that agree not to drink alcoholic beverages or use any drugs during the study

          -  Patients with local, locally advanced or metastatic HER2+ breast carcinoma as
             diagnosed on biopsied tissue by immunohistochemistry or fluorescence in situ
             hybridization (FISH).

        Exclusion Criteria:

        Patients will not be included in the study if one of the following criteria applies:

          -  Patients who have any other life-threatening illness or organ system dysfunction,
             which in the opinion of the investigator would either compromise patient safety or
             interfere with the evaluation of the safety of the test radiopharmaceutical
