Who can take part

  • Able to provide written informed consent
  • Age greater than or equal to 19 years
  • Biopsy-proven, well-differentiated grade 1 - 3 NET
  • Gastroenteropancreatic tumors (e.g. carcinoids, gastrinoma, insulinoma, glucagonoma, VIPoma, etc.), functioning and non-functioning
  • Sympathoadrenal system tumors (phaeochromocytoma, paraganglioma)
  • Pulmonary NET, functioning and non-functioning
  • Easter Cooperative Oncology Group (ECOG) ≤ 2
  • Ki67 ≤ 55%
  • Progressive disease demonstrated by RECIST 1.1 criteria within the 6 months preceding the study
  • Patients with other evidence of progressive disease that is not demonstrated on CT (like rising biomarkers) may be included, at the discretion of the Tumour Review Board
  • If response to other treatments is considered adequate according to other criteria, the Tumour Review Board may consider excluding the patient from participation in the study
  • Tumour Review Board confirmation of suitability to proceed to PRRT treatment and enrollment in this trial
  • Positive PET SSR imaging (Krenning score 2 or higher) in previous 6 months (68Ga-DOTATOC, 68Ga-DOTATATE, 18F-AmBF3-TATE). If PET SSR imaging is not available 111In-penetreotide scintigraphy (Octreotide scan) is acceptable
  • Adequate laboratory parameters within two weeks of enrollment
  • Kidneys; Serum creatinine ≤ 150 µmol/L; GFR ≥ 40 ml/min (using plasma clearance values)
  • Marrow; Hemoglobin ≥ 80 g/L; WBC ≥ 2 x 109/L; Platelets ≥ 75 x 109/L; Liver
  • Total bilirubin ≤ 3 x upper limit of normal (ULN)
  • ALT ≤ 3 x ULN or ≤ 5 x ULN if liver metastasis
  • Alkaline phosphatase ≤ 3 x ULN or ≤ 5 x ULN if liver metastasis
  • Subject's ability to comply with scheduled visits, treatment plans, laboratory tests, imaging tests, and other procedures required as detailed in the protocol

Who cannot take part

  • Women and men of childbearing potential Procreation; Women: pregnancy test done before enrollment before each treatment cycle. And subject must use adequate contraception for the duration of therapy, be surgically sterile, or post-menopausal; Men: must be surgically sterile or use adequate contraception for the duration of the therapy
  • Curative medical or surgical treatment, local liver embolization, or debulking are appropriate options
  • Radiotherapy to target lesions ≤ 12 weeks ago or to more than 25% of bone marrow
  • PRRT at any time prior to randomization in this study
  • Systemic therapy (chemotherapy) within 4 weeks of PRRT and other locoregional therapies (radioisotope, embolization) within 12 weeks prior to enrollment. Ongoing use of somatostatin analogs for control of symptoms is allowed
  • Patient with another non-cutaneous (excluding melanoma) active cancer requiring therapeutic intervention
  • Co-morbidities that could, in the opinion of the PI, interfere with safe delivery of PRRT (like urinary incontinence, psychiatric illness), uncontrolled congestive heart failure (NYHA II, III, IV)
  • Life expectancy is less than 12 weeks
  • Known brain metastases (unless treated and stable for more than 3 months)
  • Breastfeeding (if patients elect to discontinue breast feeding, they can participate in the trial)

About the trial

What the trial wants to find out

This study is to assess if personalized peptide receptor radionuclide therapy (PRRT) with 177Lu-DOTATOC results in fewer adverse events than standard PRRT. Subjects will be randomized to either receive personalized or standard PRRT. Personalized PRRT will be determined based on dosimetry calculations after the first cycle. In addition comparisons, will be made with progression-free survival, serial CT imaging, ctDNA, and quality of life questionnaires. Subjects will be followed for 5 years or until they have progression and are switched to another systemic treatment (not including treatment with somatostatin analogues).

The 2 groups in the trial

  • Standard PRRTExisting treatment, for comparison

    For standard PRRT 177Lu-DOTATOC therapy, the administered activity will be 7.4 GBq ± 10% as an intravenous infusion over a time of 10 to 30 minutes.

    Treatment: 177Lu-DOTATOC

  • Personalized PRRTTreatment being tested

    For 177Lu-DOTATOC therapy, for the first cycle the administered activity will be 7.4 GBq ± 10% as an intravenous infusion over a time of 10 to 30 minutes.Subsequent cycles will be adjusted based on dosimetry calculations.

    Treatment: 177Lu-DOTATOC
