| Measure | Time frame |
|---|---|
| Main Objective: To characterize preliminary targeting properties of [68Ga]-NeoBOMB1 in patients with malignancies known to overexpress GRPR.; Secondary Objective: •To assess safety and tolerability of a single diagnostic dose of [68Ga]-NeoBOMB1 administered as an intravenous bolus injection. •To assess the bio-distribution, pharmacokinetics, radiation dosimetry, and absorbed doses in critical organs for [68Ga]-NeoBOMB1 in a limited set of patients. •To establish the optimal threshold, expressed as Standardized Uptake Value (SUV), to discriminate Positron Emission Tomography (PET) imaging positive results from negative ones. •To estimate the [68Ga]-NeoBOMB1 PET imaging performance lesion-based and patient-based relative to a comparable standard imaging practice (eg PET, CT) according to the tumour type. •To estimate the [68Ga]-NeoBOMB1 PET diagnostic performance lesion-based and patient-based relative to the GRPR histopathology findings (e.g. IHC) ; Primary end point(s): •Number and location of tumour lesions detected by [68Ga]-NeoBOMB1 overall and for each tumour type •Calculation of the ratio tumour/background SUV and calculation of percentage absorbed dose in tumour overall and for each tumour type. ; Timepoint(s) of evaluation of this end point: Immediately after radiotracer injection, 4 scans with 6-7 bed positions will be acquired at approximately 15min, 1h±15min, 2h±15min and 4h±30min p.i. CT low dose attenuation scans will be acquired after every PET scan. PET data will be corrected for photon attenuation, dead-time, random events and scatter. A whole-body high dose CT will be acquired only if the conventional imaging of the patient is older than 1 month. Patients of the non-dosimetry group will undergo 2 whole-body PET/CT scans at 90±30 min and at 150±30 min. Patients with prostate cancer wil | — |

|---|---|
| Secondary end point(s): •Standard safety parameters (clinical monitoring, laboratory, ECG) •Tolerability and safety of the administration of a diagnostic dose of [68Ga]-NeoBOMB1 in patients with malignancies known to overexpress GRPR as determined by absence of: -increased number of SAEs compared to other peptide-based radiotracers; -clinically relevant changes of physiological parameters (blood pressure, heart rate, ECG findings) •Generation of decay corrected tissue TACs from [68Ga]-NeoBOMB1 PET/CT images in normal organs, tumour lesions. •Quantification of urinary excretion of [68Ga]-NeoBOMB1 •Calculation of half-life of [68Ga]-NeoBOMB1 in blood •Generation of non-decay-corrected time activity curves from [68Ga]-NeoBOMB1 PET/CT images in normal organs, tumour lesions •Calculation of residence times in organs and tumour lesions of [68Ga]-NeoBOMB1 •Calculation of absorbed doses and effective whole body dose of [68Ga]-NeoBOMB1 •Calculation of the SUV of each lesion •Number and location of tumour lesion detected by [68Ga]-NeoBOMB1 in comparison with comparable standard imaging modalities such as FDG-PET •Calculation of the [68Ga]-NeoBOMB1 PET overall, positive and negative agreement on a lesion-by-lesion basis as well as on a patient basis relative to the standard imaging overall and for each tumour type •Comparison of number of patients with tumour lesions detected and number of tumour lesions detected by [68Ga]-NeoBOMB1 with cytology and/or histopathology from archival and/or recent biopsy specimens •Calculation of the [68Ga]-NeoBOMB1 PET sensitivity and specificity on a lesion-by-lesion basis for all lesions with associated biopsy data, and on a patient basis relative to histopathology / cytology data ; Timepoint(s) | — |
