#2909 Serotonin-Secreting NeuroEndocrine Neoplasms of the Pancreas: Which Are the Primary Pancreatic Carcinoids?
Introduction: Serotonin-secreting pancreatic neuroendocrine neoplasms (5-HT-secreting pNENs) are very rare. They are characterised by high urinary 5-hydroxyindole-acetic acid (5-HIAA) levels (or high serum 5-HT levels).

#121 Serotonin synthesis inhibitors: a novel approach for managing gastrointestinal symptoms in carcinoid syndrome
Introduction: Carcinoid syndrome (CS) occurs when metastatic carcinoid tumors secrete large amounts of serotonin (5-HT) and other bioactive substances into systemic circulation, causing a variety of symptoms, including GI symptoms such as profound diarrhea. Reduction in 5-HT production by the tumor would be expected to improve symptoms in patients with CS.

#394 Efficacy of Telotristat Etiprate in Refractory Carcinoid Syndrome: Results of a Randomized, Placebo-controlled, Multicenter Study
Introduction: Diarrhea associated with carcinoid syndrome (CS) has been attributed to excess serotonin. Telotristat etiprate is an oral serotonin synthesis inhibitor that decreases peripheral serotonin production.

#396 Telotristat Etiprate Produces Clinical and Biochemical Responses in Patients with Symptomatic Carcinoid Syndrome: Preliminary Results of an Ongoing Phase 2, Multicenter, Open-label, Serial-ascending, European Study
Introduction: Excess serotonin (5-HT) may cause gastrointestinal (GI) symptoms (e.g., diarrhea) in carcinoid syndrome (CS) patients. Telotristat etiprate is an oral serotonin synthesis inhibitor designed to reduce peripheral 5-HT levels and alleviate GI distress.

#870 Telotristat Etiprate (TE) in a Cohort of Carcinoid Heart Disease Patients in Two Phase 2 Trials
Introduction: Serotonin is a key mediator of carcinoid syndrome (CS). High levels of urinary 5-hydroxyindoleacetic acid (u5-HIAA, a serotonin metabolite) have also been linked with carcinoid heart disease (CaHD). Telotristat etiprate (TE), a novel, oral inhibitor of serotonin synthesis, is in Phase 3 development for the treatment of CS.

#1068 Telotristat Etiprate in a Subset of Carcinoid Syndrome Patients Who Have High Levels of Urinary 5-hydroxyindoleacetic Acid and Frequent Flushing
Introduction: Serotonin is a key mediator of carcinoid syndrome (CS). CS patients (pts) with high levels of urinary 5-hydroxyindoleacetic acid (u5-HIAA, a serotonin metabolite) and >3 flushing episodes/day are at increased risk of developing carcinoid heart disease (CaHD).

#3075 Telotristat Makes Significant Difference on Symptoms and Serotonin Levels in a Population with Widespread GI-NET and Severe Carcinoid Syndrome
Introduction: In spite of new treatments like PRRT or everolimus there is a clinical need for systemic therapies that complement SSAs (somatostatin analogs) and antidiarrheal agents in the treatment of carcinoid syndrome, a late stage problem in s-i-NET. Telotristat is a promising addition to our therapeutic arsenal.

#2905 DNA Methyltransferase Inhibitor Hydralazine Induces Upregulation of Somatostatin Type 2 Receptors in Human Neuroendocrine Tumor Cells
Introduction: Epidrugs like DNA methyltransferase inhibitors (DNMTi) can increase somatostatin receptor type 2 (SST2) expression in neuroendocrine tumor (NET) cells in vitro and in vivo. This effect could be used for NET patients with low SST2 expression who are currently ineligible for somatostatin analogue (SSA) treatment. However, the DNMTi known to stimulate SST2 have either a high toxicity profile or are not yet approved.

#2988 Epigenetic Treatment with Histone Deacetylase Inhibitor Enhances Uptake of [111In]In-DOTA-TATE by Increased SST2 Expression on Neuroendocrine Tumor Cells
Introduction: The somatostatin-2 receptor (SST2) is a target for peptide receptor radionuclide therapy (PRRT) in neuroendocrine tumors (NETs). By using epigenetic drugs, which can regulate gene transcription, PRRT efficacy may be further improved due to enhanced SST2 expression.

#2840 A Real-World Study of Patients with Carcinoid Syndrome at King’s College Hospital on Long-Term Telotristat Therapy
Introduction: Telotristat ethyl is a tryptophan hydroxylase inhibitor that has been shown to be effective against symptoms of carcinoid syndrome refractory to standard somatostatin analogue therapy by directly inhibiting serotonin production. While clinical trials have established short-term efficacy of the drug, we report an exploratory real-world study of 15 patients with metastatic neuroendocrine tumours on long-term Telotristat (median duration=8 months).
