What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Mean abdominal pain scores as measured by the ESM tool.
Time Frame: 14 weeks (i.e. once during one week before linaclotide treatment, once during one week during linaclotide treatment and once during one week after the 12 week treatment period).
|
Weekly average of mean abdominal pain scores per day on the ESM-PROM per period (i.e.
baseline, after 4 weeks and after 12 weeks).
Mean scores per day will be calculated, followed by calculating the mean of those 7 scores.
|
14 weeks (i.e. once during one week before linaclotide treatment, once during one week during linaclotide treatment and once during one week after the 12 week treatment period).
|
Maximum abdominal pain scores as measured by the ESM tool.
Time Frame: 14 weeks (i.e. once during one week before linaclotide treatment, once during one week during linaclotide treatment and once during one week after the 12 week treatment period).
|
Weekly average of the maximum abdominal pain scores per day on the ESM-PROM per period (i.e.
baseline, after 4 weeks and after 12 weeks).
Maximum scores per day will be determined, followed by calculating the mean of those 7 scores.
|
14 weeks (i.e. once during one week before linaclotide treatment, once during one week during linaclotide treatment and once during one week after the 12 week treatment period).
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of bowel movements.
Time Frame: 14 weeks (i.e. once during one week before linaclotide treatment, once during one week during linaclotide treatment and once during one week after the 12 week treatment period).
|
Number of complete spontaneous bowel movements per week, as measured by the ESM tool.
|
14 weeks (i.e. once during one week before linaclotide treatment, once during one week during linaclotide treatment and once during one week after the 12 week treatment period).
|
Symptom scores for other symptoms than abdominal pain, as measured by the ESM tool.
Time Frame: 14 weeks (i.e. once during one week before linaclotide treatment, once during one week during linaclotide treatment and once during one week after the 12 week treatment period).
|
Symptom scores for non-GI physical symptoms, psychological symptoms, contextual information and information on food and drug intake.
|
14 weeks (i.e. once during one week before linaclotide treatment, once during one week during linaclotide treatment and once during one week after the 12 week treatment period).
