The purpose of this study is to assess the safety and tolerability of 68Ga-OPS202 used for the diagnosis of gastroenteropancreatic neuroendocrine tumors (GEP NETs).

68Ga-OPS202 Study for Diagnostic Imaging of GEP NET

An Open-label, Micro-dosing Study to Evaluate Safety, Biodistribution, Dosimetry and Preliminary Efficacy of Two Single 68Ga-OPS202 Doses for the Diagnostic Imaging of Somatostatin Receptor-positive Gastro-entero-pancreatic Neuroendocrine Tumors (GEP NET) Using Positron-emission Tomography / Computed Tomography (PET/CT)

An AE was defined as any untoward medical occurrence in a participant administered a IP and which does not necessarily have a causal relationship with this treatment. For this study, all AEs were regarded as 'treatment emergent', i.e., not seen before administration of the IP or, if already present before administration, worsened after start of administration. An SAE was defined as an event that led to death, was life threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect. An ADR was defined as an AE with probable, possible or unlikely relationship to the administration of 68Ga-OPS202.

Laboratory assessments included hematology, blood biochemistry and urine analysis. Vital signs included systolic and diastolic blood pressure, heart rate and axillary body temperature. Cardiac safety was assessed by 12-lead ECGs and physical examination included general appearance, head, neck, eyes, ears, nose, throat, respiratory, cardiovascular, gastrointestinal, musculoskeletal, neurological, endocrine, lymphatic, dermatological, psychological/psychiatric, abdomen, and genitourinary body systems. All medications (including herbal products) taken from visit 1 (Day 0) to visit 3 (7-15 days after visit 2 (3-4 weeks after visit 1), end of the study) were recorded in the participant's case report form.

At visit 1, after administration of 15 μg 68Ga-OPS202, a dynamic scan was performed in kidney region over first 30 minutes; static scans were performed from head to sub-inguinal region at 0.5, 1, 2 and 4 h post-injection. At visit 2, after administration of 50 μg 68Ga-OPS202, a static scan was performed from head to sub-inguinal region at 1 h post-injection. A previous somatostatin receptor scan had been performed within 6 months prior to Day 0. Lesions were classified into malignant and benign by readers. Lesion matching was performed between somatostatin receptor scan and 1 h-68Ga-OPS202 receptor scans at visit 1 and visit 2. Number of lesions for each organ/tissue and overall were calculated and absolute numbers reported. Two different read sessions were held to generate data sets for evaluation of target variables. Statistical comparisons were only feasible for those organs/ tissues that had sufficient participants with lesions detected.

Tumor contrast in PET imaging was determined by qualitative visual analysis. 68Ga-OPS202 binding was present if at least one lesion, regardless of nature, was detected within respective tissue location. Percentages were based on number of participants with available scan at corresponding time point.

At visit 1, after administration of 15 μg 68Ga-OPS202, a dynamic scan was performed in kidney region over the first 30 minutes (0-0.5 h); static scans were performed from head to sub-inguinal region at 0.5, 1, 2 and 4 h post-injection. At visit 2, after administration of 50 μg 68Ga-OPS202, a static scan was performed from head to sub-inguinal region at 1 h post-injection. A previous somatostatin receptor scan had been performed within 6 months prior to Day 0. Lesions were classified into malignant and benign lesion by the readers according to their experience. Lesion matching was performed between the somatostatin receptor scan and the 1 h-68Ga-OPS202 receptor scans at visit 1 and visit 2. The mean SUVmax of lesions (mean of all identified lesions in the lymph node and liver) was summarized by nature of the lesions (malignant, benign). Statistical comparisons were only feasible for those organs/ tissues that had sufficient participants with lesions detected.

The mean SUVmax of all identified lesions in the respective organ/tissue was determined. Statistical comparisons were only feasible for those organs/ tissues that had sufficient participants with lesions detected.

Lesion matching was performed between somatostatin receptor scan and 1 h-68Ga-OPS202 receptor scans at visit 1 and visit 2. Mean SUVmax of all selected ROIs in corresponding RT was determined. Corresponding RTs were adjacent healthy regions (1 to 3 healthy regions were identified for each lesion), i.e. located in same organ and/or region as lesion. RTs were determined in tissue locations with malignant lesions only. ROIs were also selected in muscle tissue, which was used as an additional reference region. Statistical comparisons were only feasible for those organs/ tissues that had sufficient participants with lesions detected.

The mean SUVmax of all selected ROIs in the corresponding RT was determined. RTs were determined in tissue locations with malignant lesions only. ROIs were also selected in muscle tissue, which was used as an additional reference region. Statistical comparisons were only feasible for those organs/ tissues that had sufficient participants with lesions detected.

The tumor contrast, i.e. the SUV ratio for tumor (malignant lesion)-to-background (3D-SUV-R) of a single lesion was defined as: 3D-SUV-R = SUVmax of lesion / mean of SUVmax of corresponding RTs. Statistical comparisons were only feasible for those organs/ tissues that had sufficient participants with lesions detected.

The tumor contrast, i.e. the SUV ratio for 3D-SUV-R of a single lesion was defined as: 3D-SUV-R = SUVmax of lesion / mean of SUVmax of corresponding RTs. Statistical comparisons were only feasible for those organs/ tissues that had sufficient participants with lesions detected.

The tumor contrast, i.e. the SUV ratio for 3D-SUV-R of a single lesion was defined as: 3D-SUV-R = SUVmax of lesion / mean of SUVmax of corresponding RT. For percent change, 68Ga-OPS202 receptor scan is compared to previous somatostatin receptor scan.

For determining a suitable time window for PET/CT with 68Ga-OPS202, the scans after administration of the 15 μg peptide dose were analyzed and the time point with the highest lesion number per tissue location and overall were determined. If the highest number of lesion was detected at more than one time point, the earliest time point was used.

The time point with the highest mean 3D-SUV-R per tissue location were determined. If the highest mean 3D-SUV-R was detected at more than one time point, the earliest time point was used.

The assessment of every diagnostic 68Ga-OPS202 PET/CT scan of session 2 was rated by the reader from 1 to 5, where 1=worst diagnostic scan and 5=best diagnostic scan. Higher score indicates a better scan.

Ipsen

The SAF included all participants of the FAS who received the IP, regardless of any protocol deviations.

Participants received a single dose of the OPS202 peptide (15 \[± 5\] μg on Day 0. All doses were labeled with 68Ga at a fixed dose of 200 MBq (± 25%) per injection. 68Ga-OPS202 was administered intravenously over a time period of less than 1 minute prior to 3D PET/CT scan. As per the sequential dosing scheme, on Day 21, participants then received a single dose of 50 (± 15) μg of 68Ga-OPS202 prior to 3D PET/CT.
