- Primary Outcome Measures
Name Time Method Number of Participants With Treatment-Emergent Adverse Events (TEAEs) First dose of study drug (Day 1) up to 15 days post last dose (approximately up to 236 weeks) An adverse event (AE) is defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not considered drug-related. An AE includes any noxious, pathological, or unintended change in anatomical, physiological, or metabolic functions as indicated by physical signs or symptoms occurring in any phase of the clinical study whether or not considered related to the study medication. A TEAE is an AE that occurs or worsens after receiving study drug.
- Secondary Outcome Measures
Name Time Method Change From Baseline in European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ-C30) Score at Each Visit Baseline, Weeks 24, 48, 72 and 84 QLQ-C30 is a standardized 30-item scale to assess health-related quality of life composed of 5 functional scales (physical functioning \[5 items\], role functioning \[2 items\], emotional functioning \[4 items\], cognitive functioning \[2 items\], and social functioning \[2 items\]); 3 symptom scales (fatigue \[3 items\], nausea/vomiting \[2 items\], and pain \[2 items\]); a global health status (GHS) /quality of life (QOL) scale \[2 items\]; 6 single items (dyspnoea, insomnia, appetite loss, constipation, diarrhoea, and financial difficulties). 28 questions answered:1 (not at all) to 4 (very much) and 2 questions on overall health/QOL answered:1 (poor) to 7 (excellent). All of the scales and single-item measures are transformed to a score:0 to 100. For functioning scales and global QOL higher scores indicate better functioning (a positive change from Baseline indicates improvement); for symptom scales higher scores indicate more severe symptoms (a negative change from Baseline indicates improvement).
Change From Baseline in Gastrointestinal Symptoms of Carcinoid Neuroendocrine Tumors (GI.NET21) Score at Each Visit Baseline, Weeks 24, 48, 72 and 84 GI.NET21 is a standardized 21-item scale composed of both multi-item scales and single-item measures that include 5 functional scales (gastrointestinal (GI) \[5 items\], endocrine \[3 items\], treatment-related \[3 items\], social functioning \[3 items\], and disease-related worries scale \[DRWS\] \[3 items\]) and 4 single items (muscle and bone pain symptom (BPS), sexual functioning, communication function (CF), body image and information about the disease). Each item is scored from 1 (not at all) to 4 (very much). All of the scales and single-item measures are transformed to a score of 0 to 100. For functioning scales higher scores indicate better functioning (a positive change from Baseline indicates improvement); for symptom scales higher scores indicate more severe symptoms (a negative change from Baseline indicates improvement).
Percentage of Participants With Adequate Relief as Per Subjective Global Assessment Question Baseline, Weeks 12, 24, 36, 48, 60, 72 and 84 Participants were asked to respond to the following question: "In the past 7 days, have you had adequate relief of your carcinoid syndrome bowel complaints such as diarrhea, urgent need to have a bowel movement, abdominal pain, or discomfort? The percentage of participants reporting adequate relief (answered Yes) were reported.
Change From Baseline in Subjective Global Assessment of Carcinoid Syndrome Symptoms on 11-Point Numeric Scale at Each Visit Baseline, Weeks 12, 24, 36, 48, 60, 72 and 84 Participants were asked the following question to assess global symptoms associated with carcinoid syndrome (CS) on an 11-point scale: "Rate the severity of your overall carcinoid symptoms over the past 7 days on a scale from 0 to 10, where 0=no symptoms and 10=worst symptoms ever experienced. A negative change from baseline indicated improvement.
