E.1.1.1 | Medical condition in easily understood language |
|
E.1.1.2 | Therapeutic area | Diseases [C] - Cancer [C04] |
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective is to assess the contribution of HER2-PET to subsequent anti-HER2-therapy decisions, in patients suspected of metastatic or locally recurrent HER2-positive breast cancer, with a clinical dilemma defined as failure of standard work up to evaluate the HER2 receptor status of their disease. |
|
E.2.2 | Secondary objectives of the trial |
To determine the clinical value of HER2-PET to improve diagnostic and therapeutic understanding for the referring physician.
To evaluate the concordance of HER2-PET with standard conventional work-up.
To analyze the correlation between 89Zr-trastuzumab uptake of the tumor lesions and HER-2 expression on CTCs.
|
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
•Patients with a history of histological and/or cytological proven HER2-positive primary breast cancer. HER2-positivity is defined as:
i. HER2 immunohistochemical score of 3+, or
ii. HER2 immunohistochemical score of 2+ and positive FISH for HER2/c-erbB2 amplification.
•Patients with suspected metastatic disease or local recurrence of HER2-positive breast cancer and a clinical dilemma:
i.in whom standard work up with imaging has failed to solve the clinical dilemma (diagnostic/therapeutic), leaving issues with regard to HER2 status of lesions and
ii.in whom a biopsy is desirable but cannot (easily) be performed due to technical or patient factors or otherwise.
•Standard work-up with imaging is defined as CT chest and abdomen, bone
scintigraphy, as well as FDG-PET.
•Age >18 years of age.
•WHO performance status 0-2.
•Signed written informed consent.
•Able to comply with the protocol. |
|
E.4 | Principal exclusion criteria |
1.Pregnant or lactating women.
2.Prior allergic reaction to immunoglobulins or immunoglobulin allergy.
3.Inability to comply with study procedures
|
|
E.5 End points |
E.5.1 | Primary end point(s) |
Concordance between HER2-PET results and anti-HER2 therapy is defined as HER2 positive lesion(s) on HER2-PET and subsequent anti-HER2 therapy; or no HER2 positive lesions on HER2-PET and no subsequent anti-HER2 therapy. It is considered a clinically relevant contribution of HER2-PET to anti-HER2-therapy decisions if there is a concordance in at least 2/3 of included patients. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Up to 6 weeks before HER2-PET, up to 4 weeks after HER2-PET and more than 3 months after HER2-PET |
|
E.5.2 | Secondary end point(s) |
Secondary endpoints are
•Correlation of HER2-PET results and questionnaire results regarding clinical value of HER2-PET for the referring clinician
•Correlation of HER2-PET results with standard conventional work-up
•Correlation of HER2-PET results and HER-2 expression by CTCs.
|
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
