Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Treatment: Drugs - Telotristat etiprate
Treatment: Drugs - Placebo-matching telotristat etiprate

Experimental: 250 mg Telotristat Etiprate - 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.

Experimental: 500 mg Telotristat Etiprate - 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.

Placebo comparator: Placebo - 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.

Experimental: Telotristat Etiprate Open-Label Extension - 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.

Summary
Brief summary
The primary objective of the study is to confirm that at least 1 or more doses of telotristat etiprate compared to placebo is effective in reducing the number of daily bowel movements (BMs) from baseline averaged over the 12-week double-blind portion (Treatment Period) of the trial in patients not adequately controlled by current SSA therapy.
