#4663 CAREFNDR: A phase III, randomised, parallel group, placebo-controlled study to evaluate the efficacy and safety of paltusotine in adults with carcinoid syndrome due to well-differentiated neuroendocrine tumours

Introduction: Paltusotine is a once-daily, oral, nonpeptide, selective SST2 receptor agonist in development for carcinoid syndrome (CS) treatment. In a Phase 2, open-label, dose-ranging study, paltusotine reduced the frequency and severity of CS symptoms and was well tolerated (NCT05361668).

#4181 High prevalence of deficiencies in fat-soluble vitamins, minerals and trace elements but no relation with malnutrition in patients with gastroenteropancreatic neuroendocrine tumors using somatostatin analogues

Introduction: Since 2019 the Global Leadership Into Malnutrition (GLIM) criteria exist for diagnosing malnutrition. Patients (pts) with gastoenteropancreatic (GEP) neuroendocrine tumors (NETs) treated with somatostatin analogues (SSAs) are at risk of malnutrition. Deficiencies in fat-soluble vitamins, minerals and trace elements (micronutrients) are not part of the GLIM criteria but frequently reported in pts with GEP-NETs treated with SSAs.

#4173 The global leadership into malnutrition criteria reveals a high percentage of malnutrition which negatively influences overall survival in patients with gastroenteropancreatic neuroendocrine tumors (GEP-NETs) treated with somatostatin analogues

Introduction: Patients (pts) with GEP-NETs treated with somatostatin analogues (SSA’s) are at risk of malnutrition. This has been reported, using weight loss or body mass index (BMI) only. The Global leadership into malnutrition (GLIM) criteria include weight loss, BMI and sarcopenia. In pts with other types of cancer the presence of malnutrition, has a negative effect on overall survival (OS). In pts with GEP-NETs treated with SSA’s this has not been explored before.

#4161 177Lu-DOTATATE (177Lu) efficacy in metastatic well-differentiated neuroendocrine tumors (wdNET): Differences in response according to metastases (met) location

Introduction: Treatment with 177Lu is standard of care for wdNET with high somatostatin receptor expression. Patterns of response could differ between hepatic (hep) and extrahepatic (ehep) met.
