What You Need to Know Before You Apply

What is the purpose of this trial?

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.

Will I have to stop taking my current medications?

Yes, you may need to stop taking certain medications. The trial excludes participants who are currently using any medication that could affect the condition being studied or the study drug, including over-the-counter and herbal remedies, within the past 5 days.

Is prucalopride safe for humans?

Prucalopride has been studied for safety, particularly regarding its effects on the heart. A large study found that it did not increase the risk of major heart problems like heart attacks or strokes compared to another treatment for constipation.12345

How is the drug Prucalopride different from other treatments for constipation?

Prucalopride is unique because it is a 5-HT4 receptor agonist (a type of drug that stimulates specific receptors in the gut to enhance movement) and is specifically used for people who do not get relief from regular laxatives. It is particularly effective for chronic constipation and related conditions, offering an alternative when other treatments fail.678910

What data supports the effectiveness of the drug Prucalopride for treating constipation?

Research shows that Prucalopride is effective in improving bowel habits and relieving symptoms of chronic constipation, especially in patients who did not find relief with other treatments. Studies have demonstrated significant improvements in patient satisfaction and quality of life compared to a placebo.78111213

Are You a Good Fit for This Trial?

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 Are the Treatments Tested in This Trial?

Interventions

  • Placebo
  • Prucalopride
Trial Overview 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.

Published Research Related to This Trial

A study analyzing 31,542 adverse event reports from the FDA found that semaglutide, a GLP-1 analogue, has a higher potential for misuse and abuse compared to other GLP-1 receptor agonists, with significant reporting odds ratios for issues like drug abuse and withdrawal syndrome.
The findings suggest that semaglutide may be misused as a weight-loss treatment in non-obese individuals, highlighting the need for further research to fully understand its safety profile and the implications of its use outside of approved indications.
Is There a Risk for Semaglutide Misuse? Focus on the Food and Drug Administration's FDA Adverse Events Reporting System (FAERS) Pharmacovigilance Dataset.Chiappini, S., Vickers-Smith, R., Harris, D., et al.[2023]
In a study involving 2117 participants treated with semaglutide 2.4 mg for 68 weeks, gastrointestinal adverse events (AEs) like nausea and diarrhea were more common than in the placebo group, but these AEs were mostly mild and transient, with only 4.3% of participants discontinuing treatment due to them.
Weight loss with semaglutide was significant and similar in participants with and without GI AEs, indicating that the weight loss effects of semaglutide are largely independent of these gastrointestinal side effects.
