#3018 Real-Life Data for Telotristat Ethyl in Resistant-to-Treatment Carcinoid Syndrome: Is It Efficacious in Carcinoid Flushing as Well?

Introduction: Results from clinical trials with telotristat ethyl (TE) are really encouraging about its role in carcinoid syndrome-associated diarrhoea, however, its efficacy in flushing has been equivocal.

#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.

#2130 Remote Tracking of Symptoms, QoL and Wellbeing within the New Wales NET Service

Introduction: Patients with NETs have worse health-related quality of life (HRQoL) than the general population. Technological advances have significantly increased electronic patient-reported outcome (ePRO) data collection capabilities. There is little longitudinal PRO/ePRO data and limited data on gastrointestinal symptoms, particularly ‘diarrhoea’, in NET patients.

#2097 Oral Ondansetron Offers Effective Symptomatic Bridging for Carcinoid Syndrome Refractory to Somatostatin Analogues

Introduction: Somatostatin analogues (SSA) are standard for symptomatic patients with neuroendocrine tumours (NETs). However, most patients experience tachyphylaxis, and limited options exist for this refractory carcinoid syndrome (RCS). Recently, ondansetron has been associated with reduction of bowel movement in a small series.

#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).
