E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective is to evaluate the clinical utility of experimental PET scans, in the setting of MBC at first presentation. These scans include 18F-FES-PET and 89Zr-trastuzumab-PET scans at baseline, and 18F-FDG-PET for early response measurement. |
|
E.2.2 | Secondary objectives of the trial |
Secondary objectives are: a) Relation of experimental PET scans (baseline 18F-FES-PET and 89Zr-trastuzumab-PET; 18F-FDG-PET scan after 2 weeks for early response evaluation) to (progression free) survival. b) Relation of DNA sequencing, RNA expression analysis (including microRNA [miRNA] analysis) and kinome profiling of the biopsy and venous blood, of CTC count and ER/HER2 status of CTCs, as well as circulating tumor DNA to all imaging (standard and experimental), and clinical follow-up data (treatment response and survival). c) Assessment of molecular characteristics (pathological examination and molecular analysis) of primary biopsy, new baseline biopsy of a metastasis and (optional) biopsy taken during treatment and relation to all molecular, imaging (standard and experimental) and clinical follow up data (treatment response and survival). d) Assessment of cost-effectiveness of experimental PET scans. e) Quality of life assessment before and during therapy. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Patient with first presentation of MBC, regardless of ER and HER2 status of the primary tumor, who is eligible for first-line systemic therapy.
2. Patient with non-rapidly progressive MBC, not requiring urgent initiation of chemotherapy, based on clinician's evaluation which may include:
•no recent (< 2 weeks prior to screening visit) significant worsening of MBC related signs and symptoms according to patient history.
•in case of liver metastases: no significant (>50%) increase in liver function tests ASAT and ALAT in 2 weeks prior to screening visit.
3. Patients in whom standard imaging work-up of MBC was recently (≤ 28 days) performed. Standard imaging must include: CT chest/abdomen, 18F-FDG-PET and bone scintigraphy.
4. Patient with measurable or clinically evaluable (bone only) disease on recent standard work up of MBC are eligible.
5. Metastatic lesion(s) of which a histological biopsy can safely be obtained according to standard clinical care procedures.
6. Primary tumor blocks available for confirmatory central laboratory ER/HER2 testing in the UMCG. If available a snap frozen sample of the primary tumor will also be centralized in the UMCG.
7. WHO performance status 0-2.
8. Patient is able to undergo PET imaging procedures.
9. Age >18 years of age, willing and able to comply with the protocol as judged by the investigator.
10. Signed written informed consent.
|
|
E.4 | Principal exclusion criteria |
1. Contraindications for systemic treatment (as will be assigned based on biopsy and experimental scan results), either chemotherapy, hormonal therapy or anti-HER2 therapy, based on clinical judgment of treating medical oncologist and patient history.
2. Pregnant or lactating women.
3. Prior allergic reaction to immunoglobulins or immunoglobulin allergy.
4. Inability to comply with study procedures.
5. Rapidly progressive (visceral) disease requiring rapid initiation of chemotherapy.

E.5 End points |
E.5.1 | Primary end point(s) |
In patients with measurable disease: treatment response on CT at 8 weeks (day 56 ± 3), according to RECIST1.1 criteria (both per patient and per metastasis). In patients with (non-measurable) bone metastases only, clinical response to treatment: progressive disease is defined as substantial worsening of overall complaints, meriting discontinuation of therapy. (Non-)response is related to baseline 18F-FES-PET and 89Zr-trastuzumab-PET (both per patient and per metastasis analysis); and 18F-FDG-PET at 2 weeks of treatment (both per patient and per metastasis analysis). |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
8 weeks (56 +/- 3 days) after treatment start |
|
E.5.2 | Secondary end point(s) |
- The relation between progression free survival (PFS, defined as time from start of treatment until moment of documented tumor progression or death) to either positive or negative baseline 18F-FES-PET, 89Zr-trastuzumab-PET and 2 week 18F-FDG-PET.
- The relation between DNA sequencing and RNA expression analysis (including miRNA analysis) of the biopsy and venous blood samples to all molecular, imaging (standard and experimental) and clinical follow-up data (treatment response and survival).
- The relation between miRNA analysis of the baseline biopsy and a venous blood sample at baseline, and all other molecular, imaging and clinical follow-up data.
- The relation between peptide profiling of new baseline biopsy and venous blood samples (baseline and day of standard response assessment) and all other molecular, imaging and clinical follow-up data.
- The assessment of molecular changes of primary biopsy, new baseline biopsy and (optional) biopsy taken during treatment and the relation to all other molecular, imaging and clinical follow up data.
- The relation between CTC count and ER/HER2 status of CTCs at baseline and all molecular findings of the available biopsies (primary, baseline and, if feasible later biopsies) and venous blood samples, all imaging and clinical follow-up data.
- The assessment of circulating tumor DNA analysis at baseline, day of early 18F-FDG-PET and standard response assessment to the molecular findings of the available biopsies and venous blood samples, as well as to all imaging and clinical follow-up data.
- The relation between peptide profiling of the baseline biopsy and venous blood samples (baseline and day of standard response assessment), and all other molecular, imaging and clinical follow-up data.
- The relation between circulating miRNA analysis (baseline) and all other molecular, imaging and clinical follow-up data.
- The quantification of the cost-effectiveness of the experimental imaging (baseline 18F-FES-PET and 89Zr-trastuzumab-PET; 2 week 18F-FDG-PET) as described in paragraph 7.4.6.
- The assessment of patients’ QoL before and during treatment.
