Neuroendocrine tumors (NETs) represent a rare and diverse group of tumors with predominant location in the gastro-entero-pancreatic and bronchopulmonary system. At initial diagnosis 50% of the patients present with metastatic disease whereas more than 80% develop metastases in the course of the disease with liver metastases as the most frequent ones. In consideration of the variable and sometimes indolent tumor growth behaviour, risk stratification is an important need for the...

Background: The phase III, placebo-controlled, randomized TELESTAR study evaluated efficacy and safety of telotristat ethyl (TE) in patients (pts) with diarrhoea (≥4 bowel movements (BMs)/day) due to carcinoid syndrome (CS) inadequately controlled by somatostatin analogs (SSAs). TE, a tryptophan hydroxylase inhibitor, decreases peripheral serotonin levels. As add-on treatment to SSAs, TE 250 mg 3x/day (tid) and TE 500 mg tid significantly reduced BM frequency (P...

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 ti...
