Telotristat Etiprate Produces Clinical and Biochemical Responses in Patients with Carcinoid Syndrome: Results of a Phase 2, Multicenter, Open-label, Serial-Ascending Study Abstract #661

Introduction: Excess serotonin (5-HT) in patients (pts) with carcinoid syndrome (CS) is associated with symptoms including increased bowel movement (BM) frequency.
Aim(s): We evaluated the safety/tolerability of telotristat etiprate in CS with intrapatient dose escalation/2 weeks (150, 250, 350, and 500 mg tid) in pts averaging >4 BM/day, with/without concomitant somatostatin analogs.
Materials and methods: Efficacy objectives included evaluation of change in BM/day, stool form, abdominal pain, flushing, adequate relief (AR) of gastrointestinal symptoms, and urinary 5-hydroxyindoleacetic acid (u5-HIAA) levels. The maximum dose/patient was extended for 4 weeks, (total 12 weeks dosing). If a dose limiting toxicity occurred, the dose was reduced to the prior level.

#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.

#131 Efficacy and safety results from a Phase II study of pasireotide (SOM230) in the treatment of patients with metastatic NETs refractory or resistant to octreotide LAR
Introduction: Pasireotide, a multi-receptor targeted somatostatin analogue, has 30-, 5- and 39-fold greater affinity for sst1,3 and sst5 receptors, respectively, and a slightly lower affinity for sst2, than octreotide. Because of this multi-receptor binding profile, pasireotide may be effective in controlling symptoms of carcinoid syndrome in patients with gastroenteropancreatic neuroendocrine tumors (NETs) who are no longer responsive to currently available somatostatin analogues.
