#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).

#4544 Spatial and temporal intratumour heterogeneity of pancreatic neuroendocrine tumours (PanNET)

Introduction: Data derived from the study of intertumour heterogeneity have led to propose that PanNET evolution may start either from beta cells with good prognosis, or from alpha cells with sequential alterations of MDA (MENIN-DAXX/ATRX) leading to more aggressive lesions.

#4427 Surufatinib combined with hepatic artery infusion chemotherapy (HAIC) as second-line and maintenance therapy for neuroendocrine carcinoma with liver metastases: A single-arm, open-label, single-centre phase II clinical study (SuHaNec)

Introduction: Neuroendocrine carcinoma (NEC) is rare and highly aggressive, and liver metastasis leads to worse outcomes for patients (pts) with limited treatment options and poor prognosis. Surufatinib (SUR) exhibited promising antitumour activity in neuroendocrine neoplasms.
