|---|---|
| Main Objective: To evaluate the efficacy of prucalopride compared to placebo for the treatment of functional constipation in a paediatric population, aged =6 months to <18 years.;Secondary Objective: 1. Investigation of the individual symptoms defined by the Rome III criteria: bowel frequency, faecal incontinence, retentive posturing or excessive volitional stool retention, defecation pain, stool consistency, occurrence of large diameter stools. In addition use of rescue medication, abdominal pain and toilet training*. 2. Pharmacokinetics: sparse blood sampling at single dose and steady state to enable population pharmacokinetic modelling. 3. Safety and tolerability: evaluation of prucalopride treatment up to 24 weeks. *Only for older children after acquisition of toileting skills (as standard of care).;Primary end point(s): The proportion of responders, defined as subjects with an average spontaneous‡ defecation frequency of =3 times/week AND an average number of = 1 episode of faecal incontinence/2 weeks# (as calculated over week 5 to 8 of the double-blind treatment phase). ‡A spontaneous bowel movement (SBM) is defined as a non-laxative induced BM, i.e. not preceded within a period of 24 hours by the intake of a laxative agent or by the use of an enema. #Faecal incontinence will only be taken into account in children after acquisition of toileting skills.;Timepoint(s) of evaluation of this end point: According to the study design, primary endpoint will be evaluated on double-blind placebo controlled data; safety up to 24 weeks will make use of double-blind and open-label data.The first two weeks of the double-blind treatment phase will not be used for the primary efficacy analysis because of a possible effect of the use of an enema or oral laxative agent during run-in to remove the impaction. For evaluation of dose adjustment week 3 and 4 will be used. At the week 4 visit a possible dose adjustment might occur, the endpoint will therefore be determined from week | — |
Secondary
| Measure | Time frame |

| Secondary end point(s): Secondary endpoints following individual Rome III3 criteria: • The proportion of subjects with an average spontaneous defecation frequency of =3 times/week • Number of faecal incontinence episodes/week • Weekly frequency of retentive posturing or excessive volitional stool retention • Frequency of defecation pain (6-point scale; only in subjects of 3 years or older) • Stool consistency/week (4-point scale for children wearing diapers or 7-point Bristol scale for children without diapers ) • Weekly number of large stools Other secondary endpoints: • Time to first SBM • Number of SBMs/week, BMs/week and change from baseline • Amount of rescue medication used/week • Abdominal pain score/week (6-points scale; only in subjects of 3 years or older) • Global assessment of severity of constipation • Global assessment of efficacy of treatment • Weekly frequency of toilet training (only for subjects after acquisition of toileting skills);Timepoint(s) of evaluation of this end point: Diary secondary endpoints are evaluated on a weekly basis. Global assessments are done at every visit. | — |
