A Phase III Multi-center, Randomized, Open-label Study to Evaluate the Efficacy and Safety of Lutathera in Patients With Grade 2 and Grade 3 Advanced GEP-NET

Advanced Accelerator Applications·interventional·Posted Jun 3, 2019·Updated Jan 21, 2026

In Brief

A Phase 3 clinical trial evaluating Lutathera, 30 mg Octreotide long acting repeatable (LAR) (Sandostatin LAR Depot), and 2 other interventions for Gastro-enteropancreatic Neuroendocrine Tumor. Active but no longer recruiting, targeting 226 participants across 40 sites in 9 countries.

Detailed Summary

The aim of NETTER-2 was to determine if Lutathera in combination with long-acting octreotide prolongs progression free survival (PFS) in gastroenteropancreatic neuroendocrine tumor (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 were eligible, as well as patients previously treated with SSAs in the absence of progression.

Interventions

Lutatheradrug

Lutathera is a sterile radiopharmaceutical supplied as a ready-to-use solution for infusion containing 177Lu-DOTA0-Tyr3-octreotate as a drug substance with a volumetric activity of 370 MBq/mL at reference date and time (calibration time). Each Lutathera infusion continued for 30 min.

30 mg Octreotide long acting repeatable (LAR) (Sandostatin LAR Depot)drug

Sandostatin® LAR Depot (octreotide LAR) is a pharmaceutical that was available in single-use kits containing a 6-mL vial of 10 mg, 20 mg, or 30 mg strength for intramuscular injection, a syringe containing 2.5 mL of diluent, two sterile 1½" 19-gauge needles, and two alcohol wipes.

2.5% Lys-Arg sterile amino acid solutiondrug

Participants who received Lutathera were administered a concomitant 2.5% Lys-Arg solution for kidney protection, with each Lutathera dose. The 2.5% Lys-Arg solution was administered intravenously for 4 hours (infusion rate: 250 ml/h); the infusion was to start 30 minutes prior to the start of the Lutathera infusion and continue during (30 min) and up to at least 3 hours after the Lutathera infusion.

High dose 60 mg octreotide long-acting repeatabledrug

Sandostatin® LAR Depot (octreotide LAR) is a pharmaceutical that was available in single-use kits containing a 6-mL vial of 10 mg, 20 mg, or 30 mg strength for intramuscular injection, a syringe containing 2.5 mL of diluent, two sterile 1½" 19-gauge needles, and two alcohol wipes.
