Summary

This trial tests prucalopride, a medicine that helps improve bowel movements, in children and teenagers aged 3 to 17 with functional constipation. The study will check if prucalopride works and if it has any side effects. Participants will be given either a low dose or a high dose for several months, with an option to continue for a longer period. Prucalopride has been shown to improve bowel function in adults with chronic constipation.

Who is the study for?
This trial is for children and teenagers aged 6 months to 17 years with functional constipation, which means they have difficulty passing stools not caused by other health issues or medications. They must weigh at least 5.5 kg (12 lbs), be toilet-trained if over 3 years old, and experience less than three bowel movements per week among other specific criteria related to stool characteristics.
What is being tested?
The study tests prucalopride's effectiveness in improving bowel movements in young patients with functional constipation. It has two parts: the first part randomly assigns participants to a low dose of prucalopride, a higher dose, or a placebo for 12 weeks; the second part continues treatment for another 36 weeks, with placebo group members switching to prucalopride.
What are the potential side effects?
Possible side effects from prucalopride may include abdominal pain, diarrhea, headache, nausea, fatigue and an increase in heart rate. The severity of these side effects can vary between individuals.

Trial Design

5Treatment groups
Experimental Treatment
Placebo Group
Group I: Part B: Low Dose PrucaloprideExperimental Treatment1 Intervention
Participants weighing \<50 kg will receive 0.04 mg/kg of prucalopride oral solution (will draw the required volume from one bottle of 0.4 mg/mL and one bottle of placebo oral solution to account for the daily dose assigned), QD or participants weighing ≥50 kg will receive one 2 mg of prucalopride oral tablet and one placebo oral tablet, QD, for 36 weeks during the 40-week Part B Period. Prucalopride (oral solution or tablet) will be dosed depending on the participant's BW at the randomization visit.
Group II: Part B: High Dose PrucaloprideExperimental Treatment1 Intervention
Participants weighing \<50 kg will receive 0.08 mg/kg of prucalopride oral solution (will draw the required volume from two bottles of 0.4 mg/mL to account for the daily dose assigned), QD or participants weighing ≥50 kg will receive two 2 mg of prucalopride oral tablets, QD, for 36 weeks during the 40-week Part B Period. Prucalopride (oral solution or tablet) will be dosed depending on the participant's BW at the randomization visit.
Group III: Part A: Low Dose PrucaloprideExperimental Treatment1 Intervention
Participants weighing \<50 kg will receive 0.04 milligrams per kilogram (mg/kg) of prucalopride oral solution (will draw the required volume from one bottle of 0.4 milligram per milliliter \[mg/mL\] and one bottle of placebo oral solution), QD or participants weighing ≥50 kg will receive one 2 milligram (mg) of prucalopride oral tablet and one placebo oral tablet, QD, during 12 weeks in Part A. Prucalopride (oral solution or tablet) will be dosed depending on the participant's BW at the randomization visit.
Group IV: Part A: High Dose PrucaloprideExperimental Treatment1 Intervention
Participants weighing \<50 kg will receive 0.08 mg/kg of prucalopride oral solution (will draw the required volume from two bottles of 0.4 mg/mL to account for the daily dose assigned), QD or participants weighing ≥50 kg will receive two 2 mg of prucalopride oral tablets, QD, during 12 weeks of treatment period in Part A. Prucalopride (oral solution or tablet) will be dosed depending on the participant's BW at the randomization visit.
Group V: Part A: PlaceboPlacebo Group1 Intervention
Participants weighing \<50 kilograms (kg) will draw equal volumes from two bottles of placebo oral solution to account for the daily dose assigned or participants weighing ≥ 50 kg will receive two placebo oral tablets, once daily (QD), during 12 weeks in Part A. Prucalopride matching placebo (oral solution or tablet) will be dosed depending on the participant's body weight (BW) at the randomization visit.

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
Prucalopride, a selective serotonin 5-HT4 receptor agonist, stimulates colonic motility by enhancing the peristaltic reflex and accelerating colonic transit. This is particularly beneficial for patients with functional constipation as it directly addresses the underlying issue of slow bowel movements. Other common treatments include bulk-forming agents like psyllium, which increase stool bulk and trigger bowel movements; osmotic laxatives like polyethylene glycol, which draw water into the bowel to soften stools and stimulate bowel movements; stimulant laxatives like bisacodyl, which induce bowel contractions; and stool softeners like docusate, which ease stool passage by increasing water and fat penetration. Understanding these mechanisms helps patients and doctors choose the most appropriate treatment based on the specific cause and severity of constipation.
