What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants Reported With Adverse Events (AEs), Serious Adverse Events (SAEs), and Adverse Drug Reactions (ADRs)

    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.

    Measured: From start of IP administration to end of the study visit (approximately 28 to 36 days)

  2. Number of Participants With Clinical Significant Abnormalities in Laboratory Parameters, Vital Signs, Cardiac Safety, Physical Examination, and Required Concomitant Medication

    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.

    Measured: From start of IP administration to end of the study visit (approximately 28 to 36 days)

Secondary outcomes (12)
  1. Number of Malignant and Benign Lesions Detected for Session 1

    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.

    Measured: 6 months prior to Day 0; and 1 hour post-injection on Day 0 and Day 21

  2. Percentage of Participants With Lesion-Associated 68Ga-OPS202 Binding

    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.

    Measured: At 0.5, 1, 2, and 4 hour post-injection on Day 0 and 1 hour post-injection on Day 21

  3. Mean Maximum Standardized Uptake Value (SUVmax) of Malignant and Benign Lesions for Session 1

    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.

    Measured: 6 months prior to Day 0; and 1 hour post-injection on Day 0 and Day 21

  4. Mean SUVmax of Malignant and Benign Lesions for Session 2

    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.

    Measured: At 0.5, 1, 2, and 4 hour post-injection on Day 0 and 1 hour post-injection on Day 21

  5. Mean SUVmax of Reference Tissues (RT) Region of Interests (ROIs) for Session 1

    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.

    Measured: 6 months prior to Day 0; and 1 hour post-injection on Day 0 and Day 21

  6. Mean SUVmax of RT for Session 2

    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.

    Measured: At 0.5, 1, 2, and 4 hour post-injection on Day 0 and 1 hour post-injection on Day 21

  7. Mean Tumor Contrast (3D-SUV-R) of Malignant Lesions Compared to Pre-dose Scans for Session 1

    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.

    Measured: 6 months prior to Day 0; and 1 hour post-injection on Day 0 and Day 21

  8. The 3D-SUV-R of Malignant Lesions for Session 2

    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.

    Measured: At 0.5, 1, 2, and 4 hour post-injection on Day 0 and 1 hour post-injection on Day 21

  9. Percent Change in 3D-SUV-R of Malignant Lesions

    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.

    Measured: 6 months prior to Day 0; and 1 hour post-injection on Day 0 and Day 21

  10. Number of Participants at Each Time Point With the Highest Observed Lesion Number Per Tissue Location

    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.

    Measured: At 0.5, 1, 2, and 4 hour post-injection on Day 0

  11. Number of Participants at Each Time Point With the Highest Mean 3D-SUV-R Tumor Value

    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.

    Measured: At 0.5, 1, 2, and 4 hour post-injection on Day 0

  12. Best Diagnostic Scan Assessment

    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.

    Measured: At 0.5, 1, 2, and 4 hour post-injection on Day 0 and 1 hour post-injection on Day 21

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing satoreotide trizoxetan in people with Gastroenteropancreatic Neuroendocrine Tumors, run by Ipsen at 1 site in Switzerland.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 2 Oct 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 2 Oct 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants Reported With Adverse Events (AEs), Serious Adverse Events (SAEs), and Adverse Drug Reactions (ADRs) (time frame: From start of IP administration to end of the study visit (approximately 28 to 36 days)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Oct 2019.
