PET/CT Imaging of uPAR-expression in Patients With Neuroendocrine Tumors Using 68Ga-NOTA-AE105

The aim of this non-randomised, prospective study is to investigate the applicability and prognostic value of uPAR PET/CT with the radioligand 68Ga-NOTA-AE105 in patients with neuroendocrine tumors (NETs).

About this study

68Ga-NOTA-AE105 is a radioligand targeting urokinase plasminogen activator receptor (uPAR), which is a promising imaging biomarker of tumor aggressiveness. A total of 120 NET patients will be subjected to a uPAR-PET/CT scan. Follow-up will be performed (from the time of the angiogenesis PET/ CT) at 6 months for disease specific survival (DSS) and a 1 year follow-up for PFS and OS. The uptake of 68Ga-NOTA-AE105 in tumor lesions will be quantified as Standardized Uptake Values (SUVmax/SUVmean) and compared with PFS, DSS and OS (dichotomized above/below median SUVmax and analyzed by Kaplan-Meier)

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Diagnosed with gastro-entero-pancreatic Neuroendocrine Tumors (GEP-NET; grade: G1-G3) or broncho-pulmonary NET.
  • WHO performance status 0-2
  • Must be able to read and understand the patient information in Danish and to give informed consent

Exclusion criteria

  • Pregnancy
  • Breast-feeding
  • Weight more than the maximum weight limit for the PET/CT bed of the scanner (140 kg)
  • History of allergic reaction attributable to compounds of similar chemical or biologic composition to 68Ga-NODAGA-E[c(RGDyK)]2
  • In case of broncho-pulmonary NET, the subtype must not be small cell lung cancer (SCLC)

Treatment and study plan

One injection of 68Ga-NOTA-AE105

Drug

One injection of 68Ga-NORA-AE105

PET/CT

Device

Following injection of 68Ga-NOTA-AE105 the participants will be subjected to whole body PET/CT

Primary outcomes

  1. uPAR PET/CT imaging of patients with neuroendocrine tumors

    Time frame: 1 hour

    The radioligand 68Ga-NOTA-AE105 can be used to visualize neuroendocrine tumors (grade G1-G3)

Secondary outcomes

  1. uPAR PET/CT prognostic factor for progression free survival

    Time frame: 12 months

    The uptake of the 68Ga-NOTA-AE105 in neuroendocrine tumor lesions (quantified as Standard Uptake Values) is associated with progression free survival (PFS) neuroendocrine tumors (grade G1-G3)

  2. uPAR PET/CT prognostic factor for overall and disease specific survival

    Time frame: 12 months

    The uptake of the 68Ga-NOTA-AE105 in neuroendocrine tumor lesions (quantified as Standard Uptake Values) is associated with overall and disease specific free survival (PFS) neuroendocrine tumors (grade G1-G3)
