Telotristat Etiprate Open-Label Extension
Following a 3 to 4-week run-in period on stable-dose somatostatin analog (SSA) therapy (octreotide or lanreotide) participants were randomized to receive one 250 mg telotristat etiprate tablet plus one placebo-matching telotristat etiprate tablet administered three times daily for 12 Weeks in the double-blind treatment period, followed by a 36 week open-label extension period.
Following a 3 to 4-week run-in period on stable-dose SSA therapy (octreotide or lanreotide) participants were randomized to receive, one telotristat etiprate 250 mg plus one placebo-matching telotristat etiprate tablet administered 3 times daily for 1 week, followed by two telotristat etiprate (250 mg) tablets administered three times daily for 11 weeks in the double-blind treatment period, followed by a 36 week open-label extension period.
Following a 3 to 4-week run-in period on stable-dose SSA therapy (octreotide or lanreotide) participants were randomized to receive two placebo-matching telotristat etiprate tablets administered three times daily for 12 weeks in the double-blind treatment period, followed by a 36 week open-label extension period.
Patients previously assigned to 250 mg or 500 mg three times daily of telotristat etiprate were administered two 250 mg telotristat etiprate tablets three times daily in a 36 week open-label extension (OLE) period. Patients previously assigned to placebo were administered one 250 mg telotristat etiprate tablet plus one placebo-matching tablet three times daily for one week, followed by two 250 mg telotristat etiprate tablets three times daily for 35 weeks.
