    Study Title:

    A Prospective, Randomized, Controlled, Open-label, Multicenter Trial to Evaluate Efficacy, Safety and Patient-reported Outcomes of Peptide Receptor Radionuclide Therapy (PRRT) with Lutetium (177Lu) Edotreotide compared to Best Standard of Care in Patients with Well-differentiated Aggressive Grade 2 and Grade 3, Somatostatin Receptor-positive (SSTR+), Neuroendocrine Tumors of GastroEnteric or Pancreatic Origin (COMPOSE)


    The purpose of the study is to evaluate the efficacy, safety & patient-reported outcomes of peptide receptor radionuclide therapy (PRRT) with 177Lu-Edotreotide as 1st or 2nd line of treatment compared to best standard of care in patients with well-differentiated aggressive grade 2 and grade 3, somatostatin receptor-positive (SSTR+), neuroendocrine tumours of gastroenteric or pancreatic origin.


    Primary objective: To demonstrate the efficacy of PRRT with lutetium (177Lu) edotreotide in the treatment of aggressive Grade 2 (G2; Ki67 between 15 and 20, both inclusive) and Grade 3 (G3; Ki-67 above 20 up to 55, inclusive) SSTR+ GEP-NETs compared to best standard of care (investigator s choice [from the protocol comparator list]). Secondary objectives: 1. To further demonstrate the efficacy of PRRT with lutetium (177Lu) edotreotide. 2. To assess the impact of PRRT with lutetium (177Lu) edotreotide on trial patient s health-related quality of life (HRQL) and neuroendocrine functional tumor symptoms during and after therapy in comparison to best standard of care. 3. To assess the safety and tolerability of PRRT with lutetium (177Lu) edotreotide in trial patients compared to control treatment options. Exploratory objectives: To assess the association of clinical/radiological outcomes with baseline characteristics, functional images and tumor gene profiling.
