HER2 PET Imaging in Breast Cancer Patients Using [68GA]ABY-025
- Conditions
- HER2-positive Breast Cancer
- Interventions
- Other: Radiolabeled [68Ga]ABY-025
- Registration Number
- NCT02095210
- Lead Sponsor
- Dorte Nielsen
- Brief Summary
This is an open-labeled, exploratory, single center study. Patients with a big primary breast cancer (≥ 3 cm) or metastatic first line, routinely have their HER2-expression determined by biopsy. Patients having a HER2-positive tumor will be recruited to the study. A \[18F\]FDG PET/ceCT scan is performed for the measurement of uptake in the tumour and diagnosis of possible metastases. Each subject will receive a single injection of the investigational product \[68Ga\]ABY-025, followed by measurement of uptake in the tumour or metastases and in normal organs. The investigations will be repeated after HER2 directed therapy.

- Haemoglobin: > 5.0 mmol/L
- Platelets: > 50.0 x 10^9/L
- ALT, ALP: =< 3 times Upper Limit of Normal
- Bilirubin =< 2.0 times Upper Limit of Normal
- Serum creatinine: Within Normal Limits

-
Informed consent
-
- Known hypersensitivity to Dotarem® 2. Active known autoimmune disease or history of autoimmune disease 3. Active serious infection according to investigator evaluation 4. Known HIV positive or chronically active hepatitis B or C 5. Administration of other investigational medicinal product within 30 days of screening 6. Pregnant or breast-feeding 7. Women capable of childbearing not using a sufficient non-hormonal method of birth control 8. Other primary malignancies (including primary brain tumors) within the last 5 years before inclusion, with exception of sufficiently treated in situ carcinoma of the cervix, squamous carcinoma of the skin or sufficiently controlled limited basal cell carcinoma of the skin 9. Signs of any other disease, metabolic or psychological dysfunction, findings at physical examination or laboratory findings, which give reasonable suspicion of a disease or condition that would contraindicate use of the IMP, could influence the patient's compliance with the study routines or involves an increased risk for treatment-related complications.
