Integrated Safety Analysis of Telotristat Ethyl in Patients with Carcinoid Heart Disease

#1941

Introduction: Release of serotonin by neuroendocrine tumors is associated with carcinoid heart disease (CaHD), which may pose challenges for carcinoid syndrome (CS) treatment.

Aim(s): We aimed to examine the safety of telotristat ethyl (TE), a novel tryptophan hydroxylase inhibitor, in a subgroup of CS patients (pts) with a medical history of CaHD.

Materials and methods: Adverse event (AE) data were pooled from 2 Phase 3 studies in CS in which 211 pts were randomly assigned 1:1:1 to placebo (pbo), TE 250 mg, or TE 500 mg 3×/day (tid) for 12 weeks and offered open-label 500 mg tid TE in a 36-week extension.
