Brief Summary
The purpose of this study is to assess the benefit of 177Lu-DOTATATE versus interferon α-2b in patients with progressive, unresectable, non-pancreatic gastrointestinal neuroendocrine tumors resistant to therapy with somatostatin analogues, in terms of disease control.

Outcome Measures
Primary Outcomes (1)
Progression Free Survival (PFS)
PFS is defined by the time between treatment initiation and the first of the following events: * Disease progression according to RECIST 1.1; * Death of the patient from any cause; * Appearance of confirmed new lesion(s) on 68Ga-DOTATATE PET/CT or 18FDG PET/CT.
3 years [Anticipated]
Secondary Outcomes (3)
Treatment response according to RECIST 1.1 (Response Evaluation Criteria In Solid Tumors)
3 years [Anticipated]
Adverse events according to Common Terminology Criteria for Adverse Events version 4.03 (CTC 4.03-WHO criteria)
3 years [Anticipated]
Tumor 18FDG PET/CT and 68Ga-octreotate PET/CT uptake at baseline, at mid and end of treatment
3 years [Anticipated]
Study Arms (2)
Interferon alpha-2b
ACTIVE COMPARATORInterferon α-2b in a dose of 5000000 Units administered subcutaneously every second day until progression or unacceptable adverse event from a clinical or a patient point of view.
177Lu-DOTATATE
ACTIVE COMPARATORintravenous injection of 177Lu-octreotate with simultaneous infusion of an aminoacid solution
Interventions
Interferon α-2b in a dose of 5000000 Units administered subcutaneously every second day
177Lu-octreotate infusions in fixed activities of 7,4 GigaBecqurel each, given 8-11 weeks apart, injected intravenously with simultaneous infusion of an amino acid solution
Eligibility Criteria
You may qualify if:
- Adult patients (≥ 18 yrs).
- Histology-proven non-pancreatic gastrointestinal NETs.
- Disease progression under SSAs (SSAs-resistant disease). Disease progression must be documented with at least one of the following:
- Radiological disease progression (according to RECIST 1.1) on an MRI or CT over the last 12 months.
- Disease progression on a somatostatin receptor-imaging (PET/CT or SPECT/CT) over the last 12 months (apparition of new lesion(s) or increase in the transaxial plane diameter of more than 30% on the same imaging modality).
- There should be at least one target lesion. A target lesion should fulfill all the following criteria:
- Uptake higher than the physiological liver uptake on the baseline 68Ga-DOTATATE PET/CT
- Longest transaxial plane diameter ≥ 20mm measured on the CT or MRI;
- Not previously irradiated.
- Long-acting SSAs must be discontinued at least 4 weeks before the study treatment start date and, if needed, switched to short-acting analogues which must be stopped 48h before the treatment date.
- Adequate renal function with GFR ≥ 50 mL/min/1.73m2 (evaluated by 51Cr-EDTA test).
- Adequate bone marrow function with:
- Hemoglobin ≥ 9 g/dL;
- Neutrophil ≥ 1.5·109/L;
- Platelet count ≥ 100·109/L.
- +7 more criteria
You may not qualify if:
- Resectable tumor with curative intent.
- Previous PRRT or MIBG treatment.
- Presence of non-benign 18FDG-positive lesions (higher than 2 x normal liver (or thoracic aorta uptake -SUVmax- in case of liver involvement)) without significant 68Ga-DOTATATE uptake.
- Uncontrolled congestive heart failure (NYHA stade ≥ 2).
- Diffuse bone marrow infiltration on the baseline 68Ga-DOTATATE PET/CT confirmed by MRI.
- Prior external beam radiotherapy on kidneys or on more than 25% of bone marrow.
- Patients with known uncontrolled brain metastases.
- History of other active malignant disease or clinical remission less than 5 years (except in case of non melanoma skin cancer or in situ cervical carcinoma).
- Known autoimmune hepatitis.
- Patients after organ transplantation under immunosuppressive therapy.
- Patients with a significant medical, neuro-psychiatric, or surgical condition, currently uncontrolled by treatment, which, in the investigator's opinion, may interfere with completion of the study.
- Hypersensitivity to interferon α-2b or to any component of the product.
- Pregnant or lactating patients.
