Assessment of the Efficacy of E. Coli 5C in the Management of Post-Colonoscopy Symptoms
Assessment of the Efficacy of E. Coli 5C in the Management of Post-colonoscopy Symptoms: a Randomised, Double-blind, Placebo-controlled Trial.
This prospective, randomized, double-blind, placebo-controlled clinical trial will evaluate the efficacy and safety of Escherichia coli 5C (Colipral®) in adult patients undergoing diagnostic colonoscopy. Participants will be randomized in a 1:1 ratio to receive either Colipral® or placebo for 14 days immediately after colonoscopy. The study aims to determine whether Colipral® reduces post-colonoscopy gastrointestinal symptoms compared with placebo, using validated symptom and stool assessment tools, patient-reported global improvement, and safety monitoring.

Descrição detalhada
Patients undergoing diagnostic colonoscopy may experience gastrointestinal discomfort in the days following the procedure, which may be related to alterations in the intestinal microbiota induced by bowel preparation. This study is designed to evaluate whether supplementation with Escherichia coli 5C (Colipral®) can reduce post-colonoscopy gastrointestinal symptoms compared with placebo.
This is a prospective, randomized, double-blind, placebo-controlled clinical trial. Adult patients undergoing complete diagnostic colonoscopy will be screened according to predefined inclusion and exclusion criteria and enrolled after written informed consent. Participants will be randomly assigned in a 1:1 ratio to receive either Colipral® or placebo for 14 days immediately following colonoscopy. The study treatment will be administered as 2 capsules per day, with 1 capsule in the morning and 1 capsule in the evening after dinner.
Clinical assessments will be performed at baseline and at 48 hours, 7 days, and 14 days after colonoscopy, with patient global impression of change and clinically relevant improvement assessed only at Day 7 and Day 14. The primary efficacy endpoint is the between-group difference in change in Gastrointestinal Symptom Rating Scale (GSRS) total score from baseline to Day 14. Secondary assessments include numerical rating scale (NRS) symptom scores, stool consistency, bowel movement frequency, patient global impression of change, clinically relevant improvement in gastrointestinal symptoms, use of rescue medication, treatment adherence, tolerability, and adverse events.
The study is designed to assess both the clinical efficacy and safety of Colipral® in the management of post-colonoscopy symptoms in adult patients.
