Clinical Trial Summary

After renal transplantation 5 to 10% of patients experience allograft rejection. Rapid and accurate diagnosis is vital for implementation of additional immunosuppressive therapy. Currently, a renal biopsy is essential for the diagnosis of renal allograft rejection. However, this is an intervention associated with complications like bleeding, patient discomfort and hospital admission. Additionally, limited biopsy sample size may lead to false negative results. So, the introduction of a new non-invasive diagnostic tool for allograft rejection could have major implications for the care of renal transplant recipients. For the purpose of visualizing infiltrating T lymphocytes with positron emission tomography (PET), the tracer 18-Fluor-Interleukin-2 ([18F]FB-IL2) has been developed. The investigators hypothesized that a high correlation exists between [18F]FB-IL2 uptake and the extend of T cell infiltration into renal transplants with signs of rejection

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The ability of the [18F]FB-IL2 PET to detect renal transplant rejection	Uptake of [18F]FB-IL2 in the renal transplant will be correlated to inflammatory infiltrate and histological BANFF score.	At study day 2, when PET procedure is performed.
Secondary	Uptake of [18F]FB-IL2 and correlation with renal function	Uptake of [18F]FB-IL2 in the renal transplant will be correlated to renal function as measured by 24-hours urine clearance and the Modification of Diet in Renal Disease equation (MDRD).	At study day 2, when PET procedure is performed.
Secondary	Uptake of [18F]FB-IL2 and correlation with T-cell subpopulations	Uptake of [18F]FB-IL2 in the renal transplant will be correlated to T-cell subpopulations in urine and blood.	At study day 2, when PET procedure is performed.
