Impact of Concomitant Medication on Efficacy of Telotristat Ethyl – A Post Hoc Subgroup Analysis of the Phase 3 TELESTAR Study in Carcinoid Syndrome
#1940
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.
Aim(s): We aimed to explore TE efficacy in subgroups defined by concomitant therapy.
Materials and methods: 135 pts with CS and ≥4 BMs/day despite somatostatin analog (SSA) therapy were randomly assigned to receive pbo, TE 250 mg, or TE 500 mg 3×/day. Change from Baseline in BM frequency averaged over the 12-week double-blind treatment (DBT) period was analyzed in subgroups defined by use of high or standard stable dose (SSD) of long-acting (LA) SSA and by concomitant use (yes/no [Y/N]) of short-acting (SA) rescue SSAs, antidiarrheals, and narcotics. High LA SSA was defined as octreotide >30 mg/4 weeks, lanreotide >120 mg/4 weeks, or more frequent dosing of either drug.
