Summary

This study tested a special radioactive tracer (68GaNOTA-Anti-HER2 VHH1) to see if it can find HER2-positive brain metastases on PET/CT scans. Seven adult cancer patients with at least one brain lesion were enrolled. The goal was to compare tracer uptake in HER2-positive versus HER2-negative tumors to improve detection and guide treatment.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Patients who have given informed consent * Age 18 years or older * Patients with brain metastasized cancer, with at least 1 brain lesion of at least 8 mm maximal diameter, as measured by CT or MRI. * Patients with potentially HER2-positive cancer. Either a HER2 staining should have been done in standard of care, or sufficient tissue should be available for HER2-staining for study purpose. Exclusion Criteria: * Pregnant patients * Breast feeding patients * Patients with recent (\< 1 week) gastrointestinal disorders with diarrhea as major symptom * Patients with any serious active infection * 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 test radiopharmaceutical * Patients who cannot communicate reliably with the investigator * Patients at increased risk of death from a pre-existing concurrent illness
