What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants With Treatment-Emergent Adverse Events (TEAEs) in the Double-Blind Treatment Period
An adverse event (AE) was defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related. A TEAE was an AE reported after the first dose of randomized treatment on Day 1.
Measured: First dose of study drug to within 30 days of last dose of study drug in the Double-Blind Treatment Period (Up to 17.1 Weeks)
Primary: Percent Change From Baseline in Urinary 5-hydroxyindoleacetic Acid (u5-HIAA) Levels
u5-HIAA is a standard test used in clinical practice to assess neuroendocrine tumor (NET) activity and is collected as a 24-hour urine specimen. A negative change from Baseline indicates improvement.
Measured: Baseline and 12 Weeks
Number of Participants With Treatment-Emergent Adverse Events (TEAEs) in the Open-Label Extension Period
An adverse event (AE) was defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug related. A TEAE was an AE reported after the first dose of randomized treatment on Day 1.
Measured: First dose of study drug to within 30 days of last dose of study drug in the Open-Label Extension Period (Up to 52.6 Weeks)
Secondary outcomes (6)
Change From Baseline in the Number of Bowel Movements (BMs) Per Day Averaged Over 12 Weeks
Participants recorded the number of bowel movements per day in a daily diary. The total number of BMs per day were averaged over the 12-week period. A negative change from Baseline indicates improvement.
Measured: Baseline and 12 weeks
Change From Baseline in Stool Form/Consistency Averaged Across All Time-Points
Participants assessed stool form/consistency of a BM using the Bristol Stool Form Scale where: 1=hard lumps to 7=watery liquid. The daily scores were averaged over the 12-week period. A negative change indicates improvement.
Measured: Baseline and 12 Weeks
Change From Baseline in the Number of Daily Cutaneous Flushing Episodes Averaged Across All Time-Points
Participants recorded the number daily flushing episodes per day in a daily diary. The total number of flushing episodes per day were averaged over the 12-week period. A negative change from Baseline indicates improvement.
Measured: Baseline and 12 Weeks
Change From Baseline in Abdominal Pain Averaged Across All Time-Points
Participants recorded abdominal pain in a daily diary. Participants evaluated the level of any abdominal pain using an 11-point numeric rating scale, where: 0=no pain to 10=worst pain ever experienced. The average daily abdominal pain was averaged over the 12-week period. A negative change from Baseline indicates improvement.
Measured: Baseline and 12 Weeks
Change in the Frequency of Rescue Short-acting, Somatostatin Analog (SSA) Used to Treat Carcinoid Syndrome Symptoms Averaged Across All Time-Points
The frequency (the number of times) the participant used rescue with SSA to control symptoms was recorded in a daily diary. The daily number of rescue treatments with SSA was averaged over the 12- week period. A negative change from Baseline (less use of SSA) indicates improvement.
Measured: Baseline and 12 weeks
Change From Baseline in the Number of Daily BMs Averaged Over the 12-Week Double-Blind Period, Among Participants Who Were Not Receiving SSA Therapy at Baseline
Participants recorded the number of bowel movements per day in a daily diary. The total number of BMs per day were averaged over the 12-week period. A negative change from Baseline indicates improvement.
Measured: Baseline and 12 Weeks

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Telotristat etiprate in people with Carcinoid Syndrome, run by Lexicon Pharmaceuticals at 50 sites in 11 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 26 Feb 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 50 sites in Germany, United States, United Kingdom, France, Spain and 6 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 25 Sep 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Participants With Treatment-Emergent Adverse Events (TEAEs) in the Double-Blind Treatment Period (time frame: First dose of study drug to within 30 days of last dose of study drug in the Double-Blind Treatment Period (Up to 17.1 Weeks)). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02063659, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Feb 2018.
