Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: In the present study we will perform a feasibility study to demonstrate that VEGF PET imaging by using 89Zr-bevacizumab as tracer can be used to detect multiple myeloma lesions;Secondary Objective: the comparison of 89Zr-bevacizumab PET imaging with the FDG-PET scan to demonstrate whether increased angiogenesis is associated with enhanced FDG uptake. Furthermore bone marrow material will be stained to for micro vessel density (MVD) and VEGF levels. In addition we will see if there is a correlation between lesion found on the 89Zr-bevacizumab PET scan and expression of VEGF and MVD.;Primary end point(s): 89Zr-bevacizumab tracer uptake in multiple myeloma lesions;Timepoint(s) of evaluation of this end point: 89Zr-bevacizumab tracer uptake in multiple myeloma lesions | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): • The correlation between positive lesions found on the FDG-PET and lesions found on 89Zr-bevacizumab PET. • The correlation between VEGF levels and MVD in bone marrow samples of multiple myeloma patients and lesions found on 89Zr-bevacizumab PET. ;Timepoint(s) of evaluation of this end point: The scans and bone marrow samples will be evaluated directly (after they are peformed). | — |
