PLENVU versus sodium picosulfate bowel preparation for children having a colonoscopy
Official title: A Phase 3, Multicentre, Randomised (1:1), Parallel-group, Active-controlled, Central Reader Colonoscopist-blind Study to Evaluate the Bowel Cleansing Efficacy, Safety, Tolerability, Palatability, and Acceptability of PLENVU® as Compared to Sodium Picosulfate in Paediatric Participants From 1 to < 18 Years of Age in Preparation for Colonoscopy (CLARITY)
Run by Norgine · NCT07218523 · Data updated 2026-11-12
This trial will try whether PLENVU® cleans the bowel as well and is as safe and tolerable as sodium picosulfate in children under 18 preparing for a colonoscopy.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are children aged 1 to under 18 years who require a colonoscopy, weigh at least 10 kg (with ages 1 to <4 years above the 10th weight percentile), are not breastfeeding or pregnant, and can be admitted to the clinical research unit for dosing and the procedure.
✕Probably not a fit
Patients with recent severe constipation requiring repeated interventions, known or suspected GI obstruction, ileus, perforation, toxic or ischemic colitis, megacolon, or those who cannot take the oral preparations or are breastfeeding/pregnant are unlikely to benefit from participation.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This is a multicentre, randomized (1:1), active-controlled Phase 3 trial comparing PLENVU® to sodium picosulfate using a two-day split dosing regimen in paediatric participants scheduled for colonoscopy. Participants are admitted to a clinical research unit on Day 1 for intervention administration and remain for the colonoscopy on Day 2, with a safety follow-up by call or visit around Day 9. Bowel cleansing success will be measured using standard scales (e.g., Harefield and Boston bowel preparation scales) along with safety and tolerability assessments. The trial is being conducted at three Belgian centres and includes screening up to 28 days prior to dosing.
Why it matters
Potential benefit: If successful, the intervention could offer a more effective or better-tolerated bowel preparation option for children, improving colon visualization and diagnostic accuracy.
How similar studies have gone: Low-volume bowel preparations like PLENVU® have shown good efficacy and tolerability in adults, but randomized pediatric data are limited.
