Outcome Measures

Primary Outcomes (1)

  • Immuno PET can be used to visualize the immunological environment of the tumor (Glioblastoma).

    Thus, the aim of the pilot study, which follows an exploratory approach, is to evaluate PET imaging in vivo in patients using PET ligand \[18F\]JNJ-64413739 or a \[18F\] labeled equivalent. To evaluate if it is possible to visualize (visually topically deniable increased Tracer-uptake) the immunological processes in tumor or adjacent brain structures in sufficient image quality. We practice measurement by SUV (= standard uptake value) of the morphologically identified glioblastoma lesion relative to normal brain tissue: TBR (=tumor background ratio) - as a quantification of immunological processes inside the tumor.
