#62 Genome-wide DNA methylation profiling of pancreatic neuroendocrine tumors identifies distinct methylation profiles and differentially methylated gene promoter regions associated with low, medium and high grade tumors
Introduction: Integration of genetics and epigenetics has emerged as a powerful approach to studying cellular differentiation (Mikkelsen et al, 2009) and tumorigenesis (Shen et al, 2007). The study of DNA methylation is of particular importance in cancer, as causal involvement has been demonstrated and it is the most stable of all epigenetic modifications, making it a desirable marker for both early detection and treatment of tumors. Hypermethylation of CpG sites in gene promoter regions leads to decreased gene expression; if such a gene is a tumor suppressor, this leads to carcinogenesis. To date, there have been no studies of genome-wide DNA methylation profiling of NETs. This study sets out to determine the DNA methylation profiles of low, intermediate and high grade pancreatic NET liver metastases with the intention of identifying dysregulated biological pathways in the development of these tumors. A protocol for the analysis formalin-fixed paraffin embedded tissue (FFPE) has also been developed in order to study these tumors in significant numbers following this pilot study.

#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.

#823 Association Between Tumor Expression of VEGFA, VEGFR1 (FLT1), VEGFR2 (KDR), and Clinical Outcomes in Neuroendocrine Tumors
Introduction: Clinical studies have suggested efficacy of VEGF pathway inhibitors in the treatment of advanced neuroendocrine tumors (NETs).

#849 Patient-Reported Symptom Experiences Following Participation in a Study of Telotristat Etiprate for Patients with Neuroendocrine Tumors and Diarrhea Not Adequately Controlled on Octreotide
Introduction: Telotristat etiprate (LX1606), an oral tryptophan hydroxylase (TPH) inhibitor, was recently evaluated in a dose-escalation (DE) study in patients (pts) with carcinoid tumors and diarrhea not adequately controlled on octreotide.

#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.

#1224 A Randomized Open-label Phase II Study of Everolimus Alone or in Combination with Pasireotide LAR in Advanced, Progressive Pancreatic Neuroendocrine Tumors (pNET): COOPERATE-2 Trial
Introduction: Pasireotide is a somatostatin analog (SSA) that targets somatostatin receptor subtypes 1-3 and 5. An earlier phase I study showed antitumor activity of everolimus+pasireotide LAR (EVE+PAS) in NET.

#1333 Efficacy and Safety of Telotristat Etiprate in Patients with Carcinoid Syndrome not Adequately Controlled by Somatostatin Analog Therapy: Analysis of the Ongoing TELESTAR Extension Period
Introduction: TELESTAR was a pivotal, randomized phase 3 study evaluating telotristat etiprate (TE), a tryptophan hydroxylase inhibitor, among patients (pts) with carcinoid syndrome (CS). When added to somatostatin analogues (SSA), 250 mg tid and 500 mg tid TE each produced significantly greater bowel movement (BM) frequency reduction averaged over 12 weeks (wks) than placebo (PBO) plus SSA (p<0.001). Pts crossed over to open-label (OL) treatment with TE 500 mg tid after Wk 12. The extension phase (Wk 13 to Wk 48) is still ongoing

#1354 Patient Interviews in TELESTAR, a Phase 3 Study of Telotristat Etiprate, Report Meaningful Improvement in Carcinoid Syndrome
Introduction: Telotristat etiprate (TE) reduces serotonin production. In TELESTAR, a phase 3 study in patients (pts) with carcinoid syndrome (CS) on somatostatin analogues with ≥4 bowel movements (BM) per day, TE significantly reduced BM frequency (freq). Overall (n=135), durable response (DR, ≥30% reduction in BMs/day for ≥50% of the study period) was observed in 44% (250 mg tid) and 42% (500 mg tid), vs 20% on placebo (PBO); p≤0.02 for each TE vs. PBO. A subset with similar demographics to the overall trial was interviewed.

#1437 Efficacy and Safety of Everolimus in Advanced, Progressive, Nonfunctional Neuroendocrine Tumors (NET) of the Lung: A Subgroup Analysis of the Phase 3 RADIANT-4 Study
Introduction: In the phase 3, RADIANT-4 study, everolimus (EVE) improved median progression-free survival (PFS) by 7.1 months in patients (pts) with advanced, progressive, nonfunctional NET of lung or GI tract compared to placebo (PBO); HR, 0.48; 95%CI, 0.35-0.67; P<0.00001.
