COMPETE is an international, prospective, randomized, controlled, open-label, multicenter (conducted in multiple countries simultaneously) phase III clinical trial. This means that during the study, new data will be collected (prospective). Results in patients receiving the investigational treatment will be compared to a control group receiving the standard therapy with Everolimus (controlled). Patients will be randomly assigned to receive either n.c.a. Lutetium-177-Edotreotide or Everolimus, one of the current standard of care treatments (randomized). Both patients and physicians will know which drug is being administered (open-label). The study will be conducted at multiple sites across di erent countries simultaneously (multicenter).

The trial will evaluate the efficacy and safety of the targeted radiopharmaceutical n.c.a. ¹⁷⁷Lu-Edotreotide compared to the standard therapy Everolimus in patients with neuroendocrine tumors of gastroenteric or pancreatic origin (GEP-NETs). Targeted Radionuclide Therapy or Peptide Receptor Radionuclide Therapy (PRRT) is the treatment option for NETs being investigated in this trial. It is not to be confused with traditional radiation therapy, which irradiates tumors from the outside of the body.

The primary objective is to demonstrate the efficacy of Targeted Radionuclide Therapy with n.c.a. ¹⁷⁷Lu-Edotreotide to prolong median progression-free survival (mPFS) in patients with inoperable, progressive, somatostatin receptor positive (SSTR⁺) GEP-NETs, compared to Everolimus. Key secondary objectives are to assess objective response rates (ORR), defined as the proportion of patients achieving partial response (PR) or complete response (CR) as best outcome, after treatment with n.c.a. ¹⁷⁷Lu-Edotreotide compared to Everolimus and to assess overall survival (OS).

The study is conducted in Europe, North America, South Africa and Australia simultaneously in 12 countries at over 43 sites. The first patient was enrolled and treated in Australia.

300 patients with GEP-NETs will be randomized 2:1. Neither you nor your doctor will be able to choose which group you will be assigned. You are twice as likely to receive Targeted Radionuclide Therapy with n.c.a. Lutetium-177-Edotreotide than the standard therapy with Everolimus.

200 patients: Targeted Radionuclide Therapy with n.c.a. ¹⁷⁷Lu-Edotreotide with a maximum of 4 cycles, administered as an infusion at 3-monthly intervals for 9 months, or until diagnosis of progression
To protect the kidneys, 30-60 min before each cycle with Targeted Radionuclide Therapy, an Amino-Acid Solution (AAS) will be given as an infusion over 4-6 h

100 patients: Everolimus, 10 mg daily, administered orally as a tablet
