Brief Summary:
The aim of NETTER-2 is to determine if Lutathera in combination with long-acting octreotide prolongs PFS in GEP-NET patients with high proliferation rate tumors (G2 and G3), when given as a first line treatment compared to treatment with high dose (60 mg) long-acting octreotide. Somatostatin analog (SSA) naive patients are eligible, as well as patients previously treated with SSAs in the absence of progression.

Primary Outcome Measures :
- Progression Free Survival (PFS) [ Time Frame: through Week 72 until 99 PFS events are reached ]Time from randomization to the first line progression (centrally assessed according to RECIST 1.1 or death due to any cause)
Secondary Outcome Measures :
- Objective Response Rate [ Time Frame: week 16 ±1; week 24 ±1 and then every 12 ±1 weeks until Week 72 ]Rate of complete and partial responses (CR, PR) (centrally assessed according to RECIST 1.1)
- Time to Deteriration (TTD) global health status, diarrhea, fatigue, pain (EORTC QLQ-C30) [ Time Frame: every 12 ± 1 week from first treatment date until the end of treatment ]TTD is defined as the first deterioration of at least 10 points from baseline in EORTC QLQ-C30 questionnaire: global health status (TTD)-diarrhea (TTD)-fatigue, (TTD)-pain (TTD)
- Disease Control Rate (DCR) [ Time Frame: week 16 ±1; week 24 ±1 and then every 12 ±1 weeks until Week 72 ]Rate of complete response (CR), partial response (PR) and stable disease (SD) centrally assessed according to RECIST 1.1.
- Duration of Response (DOR) [ Time Frame: week 16 ±1; week 24 ±1 and then every 12 ±1 weeks until Week 72 ]Time from initially meeting the criteria for response (CR or PR) until the time of progression according to RECIST 1.1 or death due to underlying disease
- Rate of Adverse Events [ Time Frame: Lutathera: within 2 weeks before infusion and 4 ± 1 weeks after infusion. ]Rate of adverse events scored according to CTCAE grade
- Rate of laboratory toxicities [ Time Frame: Lutathera: within 2 weeks before infusion and 4 ± 1 weeks after infusion. ]Rate of laboratory toxicities scored according to CTCAE grade
- Overall Survival (OS) [ Time Frame: up to 4 years from randomization of last patient ]OS is the time from randomization date until day of death due to any cause.

Criteria
Inclusion Criteria:
- Presence of metastasized or locally advanced, inoperable (curative intent) histologically proven, well differentiated Grade 2 or Grade 3 gastroenteropancreatic neuroendocrine (GEP-NET) tumor diagnosed within 6 months prior to screening.
- Ki67 index ≥10 and ≤ 55%
- Patients ≥ 15 years of age and a body weight of > 40 kg at screening
- Expression of somatostatin receptors on all target lesions documented by CT/MRI scans, assessed by any of the following somatostatin receptor imaging (SRI) modalities within 3 months prior to randomization: [68Ga]-DOTA-TOC (e.g. Somakit-TOC®) PET/CT (or MRI when applicable based on target lesions) imaging, [68Ga]-DOTA-TATE PET/CT (or MRI when applicable based on target lesions) imaging (e.g. NETSPOT®), Somatostatin Receptor scintigraphy (SRS) with [111In]-pentetreotide (Octreoscan® SPECT/CT), SRS with [99mTc]-Tektrotyd, [64Cu]-DOTA-TATE PET/CT (or MRI when applicable based on target lesions) imaging.
- The tumor uptake observed in the target lesions must be > normal liver uptake.
- Karnofsky Performance Score (KPS) ≥ 60
- Presence of at least 1 measurable site of disease
- Patients who have provided a signed informed consent form to participate in the study, obtained prior to the start of any protocol related activities
Exclusion Criteria:
- Creatinine clearance < 40 mL/min calculated by the Cockroft Gault method

- Documented RECIST progression to previous treatments for the current GEP-NET at any time prior to randomization
- Patients for whom in the opinion of the investigator other therapeutic options (eg chemo-, targeted therapy) are considered more appropriate than therapy offered in the study, based on patient and disease characteristics

- Uncontrolled congestive heart failure (NYHA II, III, IV). Patients with history of congestive heart failure who do not violate this exclusion criterion will undergo an evaluation of their cardiac ejection fraction prior to randomization via echocardiography. The results from an earlier assessment (not exceeding 30 days prior to randomization) may substitute the evaluation at the discretion of the Investigator, if no clinical worsening is noted. The patient's measured cardiac ejection fraction in these patients must be ≥40% before randomization.

- Patients with any other significant medical, psychiatric, or surgical condition, currently uncontrolled by treatment, which may interfere with the completion of the study.
- Prior external beam radiation therapy to more than 25% of the bone marrow.
- Current spontaneous urinary incontinence
- Other known co-existing malignancies except non-melanoma skin cancer and carcinoma in situ of the uterine cervix, unless definitively treated and proven no evidence of recurrence for 5 years
- Patient with known incompatibility to CT Scans with IV contrast due to allergic reaction or renal insufficiency. If such a patient can be imaged with MRI, then the patient would not be excluded.
- Hypersensitivity to any somatostatin analogues, the IMPs active substance or to any of the excipients.
