ABSTRACT
BACKGROUND & AIMS:
Prucalopride is a selective, high-affinity agonist of the 5-hydroxytryptamine (serotonin) receptor 4 that enhances motility in the gastrointestinal tract. We performed a multicenter, randomized, placebo-controlled, double-blind, phase 3 trial to evaluate the efficacy and safety of prucalopride in children (6 months to 18 years old) with functional constipation.METHODS:
Children with functional constipation, based on the Rome III criteria, were given prucalopride (children ≤ 50 kg were given a 0.04 mg/kg oral solution; children >50 kg were given a 2-mg tablet) or placebo once daily for 8 weeks. The primary efficacy end point was the proportion of children with toileting skills who had a mean of ≥ 3 spontaneous bowel movements/week and ≤ 1 episode of fecal incontinence/2 weeks, from study weeks 5-8 (responders). Adverse events, clinical laboratory values, and electrocardiograms were monitored.RESULTS:
Efficacy and safety were assessed in 213 children (106 prucalopride, 107 placebo). Twenty-five percent were younger than 4 years old, 50% were 4-11 years old, and 25% were 12-18 years old; 55.4% were girls. At screening, 62.3% of patients in the prucalopride group and 55.1% in the placebo group had a history of fecal incontinence; 60.4% and 55.1% in the prucalopride and placebo groups, respectively, had a mean of ≤ 1 spontaneous bowel movements/week. The proportion of responders was similar between groups (prucalopride, 17.0% and placebo, 17.8%). There were no statistically significant differences in the primary efficacy end point when patients were stratified by sex, age group, or country. The incidence of treatment-emergent adverse events was similar in the prucalopride (69.8%) and placebo (60.7%) groups.CONCLUSIONS:
Prucalopride, although generally well tolerated, was not more effective than placebo in children with functional constipation. ClinicalTrials.gov Number NCT01330381.Palavras-chave
