#2262 Time to Sustained Improvement in Bowel Movement Frequency with Telotristat Ethyl: Analyses of Two Phase 3 Studies in Carcinoid Syndrome
Introduction: Telotristat ethyl (TE) is a treatment for carcinoid syndrome (CS) diarrhea used in combination with somatostatin analog (SSA) therapy. In the Phase 3, randomized, placebo-controlled, double-blind TELESTAR and TELECAST studies, CS patients received TE at 250 mg 3 times per day (tid), 500 mg tid, or placebo tid in addition to SSAs.

#1856 Relationship Between Symptoms and HRQoL Benefits in Patients (pts) with Carcinoid Syndrome (CS): A Post-Hoc Analysis of Telotristat Ethyl (TE) TELESTAR Trial
Introduction: TELESTAR previously demonstrated the efficacy and safety of TE in pts with CS experiencing >4 Bowel Movements (BM) per day despite stable-dose somatostatin analog therapy. Significantly higher rates of Durable Response (DR, predefined as Bowel Movement (BM) frequency reduction ≥30% from baseline for ≥50% of the 12 week double blind period) were observed with TE (TE 250mg: 44%, TE 500mg: 42%) vs placebo (20%).

#1940 Impact of Concomitant Medication on Efficacy of Telotristat Ethyl – A Post Hoc Subgroup Analysis of the Phase 3 TELESTAR Study in Carcinoid Syndrome
Introduction: The tryptophan hydroxylase inhibitor telotristat ethyl (TE) significantly reduced bowel movement (BM) frequency versus placebo (pbo) in patients (pts) with carcinoid syndrome (CS) in the TELESTAR study.

#1941 Integrated Safety Analysis of Telotristat Ethyl in Patients with Carcinoid Heart Disease
Introduction: Release of serotonin by neuroendocrine tumors is associated with carcinoid heart disease (CaHD), which may pose challenges for carcinoid syndrome (CS) treatment.

#1942 Telotristat Ethyl in Carcinoid Syndrome: Safety and Efficacy Results of an Open-Label Extension of the TELECAST Phase 3 Clinical Trial
Introduction: TELECAST assessed telotristat ethyl (TE), a tryptophan hydroxylase inhibitor, in patients (pts) with carcinoid syndrome (CS) with ≥1 CS symptom/sign and a mean 2.5 bowel movements (BMs) per day. Pts were somatostatin analog treated (89%), with gastrointestinal (90%; [diarrhea, 70%]) and cardiac disorders (42%), including carcinoid heart disease. At Week (W) 12, TE (250 and 500 mg 3×/day; tid) significantly reduced urinary 5-hydroxyindoleacetic acid (u5-HIAA) and BMs/day vs placebo (pbo) (p≤0.008). After W12, pts crossed over to an open-label extension (OLE) with TE 500 mg tid (W13–48).

#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.

#1812 Correlation of Plasma (p) and Urine (u) 5-HIAA Levels in Patients (pts) with Carcinoid Syndrome (CS) – Post-Hoc Analyses from the TELESTAR Study
Introduction: Telotristat ethyl (TE) is an oral tryptophan hydroxylase inhibitor in development for treating CS symptoms. During the double-blind treatment [DBT] period of the phase 3, 12-week, placebo-controlled TELESTAR study, TE was well tolerated and significantly reduced bowel-movement frequency and u5-HIAA levels compared with placebo (PBO) in NET patients with CS treated with a SSA.

#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.

#1272 Telotristat Etiprate Appears to Halt Carcinoid Heart Disease
Introduction: Carcinoid Heart Disease (CHD) is a serious complication of the Carcinoid Syndrome (in as many as 50% of patients during the course of their disease). 46% of cases operated with bioprosthetic valves develop recurrent carcinoid valvulopathy on the newly implanted tissue valves. Until now, only mechanical prosthetic valves avoid recurrent fibrosis.
