Main objective
Scope: Efficacy, Safety, Dose response, Therapy
The aim of the study is to develop an algorithm for the treatment of GEPNET patients using ItraPol and LutaPol isotope mixtures (177Lu-DOTATATE and 90Y-DOTATATE) based on personalized dosimetry.
Secondary objectives 1
- The specific goal is to assess the effectiveness and safety of personalized treatment of GEP-NET patients using 177Lu-DOTATATE and 90Y-Lu- DOTATATE mixtures compared to standard treatment of NEN patients using 177Lu-DOTATATE

Randomised Controlled | None | Group A: Treatment with [177Lu]Lu-DOTA-TATE with fixed doses of 7400 MBq radioactivity Group B: Treatment with [177Lu]Lu-DOTA-TATE with [90Y]Y-DOTA-TATE - initially in a ratio of 3700:1850 MBq/MBq. Based on imaging studies and pharmacokinetics and calculated absorbed doses in tumour, kidney and bone marrow in subsequent cycles, the ratio of 90Y to fixed 177Lu radioactivity will be individually adjusted. Group C: Treatment with [177Lu]Lu-DOTA-TATE with [90Y]Y-DOTA-TATE - initially in a ratio of 3700:1850 MBq. Based on imaging studies and pharmacokinetics and calculated absorbed doses in tumour, kidney and bone marrow in subsequent cycles, the ratio of 177Lu to fixed 90Y radioactivity will be individually selected. Group D: Treatment with [177Lu]Lu-DOTA-TATE initially with a dose of 7400 MBq and then with an individualised dose based on imaging studies and pharmacokinetics and calculated absorbed doses in the tumour, kidney and bone marrow. |

Eligibility criteria
Principal inclusion / exclusion criteria as submitted by sponsor
Inclusion criteria 1
- Associated with neuroendocrine tumour: a)Presence of advanced, unresectable, histopathologically confirmed well and intermediate differentiated (G1 and G2) neuroendocrine tumour with high expression of somatostatin receptors on somatostatin receptor imaging (SRI) PET/CT with 68Ga-DOTA-TATE performed up to 12 weeks prior to first administration of therapy b)Detection of tumour progression according to RECIST criteria 1. 1 on multiphasic CT or dynamic MR imaging within 18 months, with a qualifying study performed up to 12 weeks prior to the first administration of therapy c)Laboratory tests*: ◦ Blood count with smear Hb > 9g/dl, platelets > 100,000/μl, leukocytes > 3,000/μl, neutrocytes > 1.5,000/μl, ◦ Creatinine <120 μmol/l (1.36 mg/dl) or eGFR>45 ml/min. ◦ ALT, AspAT, total bilirubin (values not exceeding 3x the reference standard) **it is acceptable to use for qualification the results of biochemical and haematological tests that are part of the medical history if they were performed up to 12 weeks before the qualifying visit and if, in the opinion of the investigator, there is no need and no indication to repeat them Patient-related: Patient's overall Karnofsky score ≥60%. Expected survival of more than 6 months. Age over 18 years, with no upper age limit. Ability to give informed consent to participate in the study. Signing an informed consent form to participate in the study.
Exclusion criteria 1
- Cancer-related: Patient disability (Karnofsky <60) Expected survival of less than 6 months. Treatment for another malignancy less than 5 years prior to randomisation. Associated with current and past medical therapies and interventions: PRRT in the past. Chemotherapy or molecular treatment (for NEN or other cancer) in the past. Patient-related: Age under 18 years.

Endpoints
Primary and secondary outcome measures (English text)
Primary endpoints 1
- Disease progression assessed by CT or MRI according to RECIST 1.1. Timepoints of Primary End Point evaluation: control imaging investigations (CT or MRI) using the technique identical with the one based on which the patient was qualified for the trial, performed after 3,6,12,24,36,49,60 months after completion of therapy with assessment according to RECIST 1.1
Secondary endpoints 1
- Assessment of effectiveness and safety of personalized therapy. It is planned to perform biochemical tests during visit W1, during hospitalization and in the course of observation every 3 months (tests of blood morphology, urea, creatinine, eGFR, bilirubin). Total volume of blood collected at single timepoint - 6.8 ml.
