About this trial

This is an interventional diagnostic trial for Neuroendocrine Carcinoma

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Patients of either gender, aged at least 18 years.
  • Karnofsky status equal or greater than 60.
  • Life expectancy of at least 12 weeks.
  • Histologically and/or clinically confirmed and/or suspicious of NET.
  • Somatostatin-analogue scintigraphies scan with result (positive or negative) within the last 4 weeks.
  • Recent Blood test results up to 2-3 weeks as follows:(WBC:equal/higher 2*109/L; Haemoglobin: equal/higher 8.0g/Dl; Platelets: equal/higher 50x109/L; ALT, AST, AP: equal/lower 5 times ULN; Bilirubin: equal/lower 3 times ULN; Serum creatinine: within normal range or <120μmol/L for patients aged 60 years or older.
  • Negative pregnancy test in women capable of child-bearing.

Exclusion Criteria:

  • Known hypersensitivity to DOTA, to 68Gallium, to Octreotate or to any of the excipients of 68Ga-DOTATATE.
  • Therapeutic use of any somatostatin analogue, including Sandostatin® LAR (within 28 days) and Sandostatin® (within 2 days) prior to study imaging. If a patient is on Sandostatin® LAR a wash-out phase of 28 days is required before the injection of the study drug.
  • Pregnant or breast-feeding women.
  • Current somatic or psychiatric disease/condition that may interfere with the objectives and assessments of the study.

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

68Ga-DOTATATE PET scans

Arm Description

This is an open-label, single-dose diagnostic study using DOTATATE peptide, labelled with the 68Ga tracer. The radiation (imaging) dose will be 111-185MBq (3 - 5 mCi) ±25%. Imaging will start 90 ±30 minutes after injection. The diagnostic sensitivity, specificity and accuracy of the study drug are being compared with a predefined standard of truth (SOT) parameters. A comparative conventional scan, such as anatomical imaging modalities CT, ultrasound, and MRI or functional imaging using 18F-FDG and NaF PET/CT or bone scan is being used to evaluate the diagnostic efficacy of 68Ga-DOTATATE.

Outcomes

Primary Outcome Measures

Number of lesions detected by 68GA-DOTATATE compared to conventional imaging technique
We want to determine if the 68Ga-DOTATATE PET/CT scan changes care plans compared to conventional imaging/diagnostic techniques (Octreoscan, MRI).

Secondary Outcome Measures

Frequency and severity of Adverse Events
Adverse events will be collected from the time of 68Ga-DOTATATE injection until 48 hours post-injection visit. Adverse events will be classified using criteria for adverse events (CTCAE) Version 4.

5. Study Description

Brief Summary
To evaluate the concordance and discordance between results of 68Ga-DOTATATE PET-CT scan and OctreoScan ® which is considered standard of care diagnostic test for neuroendocrine cancers and other imaging modalities like CT scan/MRI as gold standard.
Detailed Description
The number of lesions that could be identified clearly as single foci will be determined for each patient. The same anatomic areas will be imaged with 68Ga-DOTATATE PET and 111In-penteoctreotide Scintigraphy to ensure relevant comparison of lesion detection. Because of confluence and inability to clearly delineate single liver lesions in some cases, liver metastases will be classified as 1 organ metastasis, independent of the number of liver metastases present. Lymph nodes smaller than 1 cm on CT or MRI and showing marked avidity for 68Ga- DOTATATE and 111In-penteoctreotide will be labeled as positive for disease. The presence of lesions will be confirmed by cross-sectional imaging of all patients with CT or MRI.
