Study summary

The study is a double-blind, placebo-controlled, crossover, randomised trial, in which enrolled subjects will be included for 18 months. This study aims to evaluate the effect of the Colipral as a Food Supplement prescribed according to the standard of care of patients suffering UC during remission phase and DGBI.

The primary objective of the study is to evaluate the variation in gut microbiota, specifically focusing on bacterial diversity and abundance, in patients with UC during the remission phase and DGBI.

The secondary objective of the study is to evaluate the clinical parameters variations (based on fecal calprotectin and IBDQ's score before and after the treatment), the severity of gastrointestinal symptoms, the quality of life, and the maintenance of the remission phase in patients with UC in remission and DGBI.

Read the detailed description

The primary endpoint will be the variation in gut microbiota analyzed through 16S rRNA gene sequencing from a fecal sample of patients presenting UC during remission phase and DGBI at three time points: T=0 (baseline, before treatment), T=1 (after 60 days of treatment A or B), and T=3 (after an additional 60 days of treatment A or B).

The secondary endpoint will be the assessment of the clinical parameters variation based on fecal calprotectin in patients presenting UC during remission phase and DGBI at three time points: T=0 (baseline, before treatment), T=1 (after an additional 60 days of treatment A or B), and T=3 (after 60 days of treatment A or B).

The severity of gastrointestinal symptoms and quality of life will be assessed using the IBDQ, IBS SSS, VAS, and Bristol Stool Scale questionnaires at three time points: T=0 (baseline, before treatment), T=1 (after 60 days of treatment A or B), and T=3 (after an additional 60 days of treatment A or B). Patients' dietary habits will be analysed using the WCRF questionnaire at the first and final visit.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Diagnosis of UC confirmed by clinical, endoscopic and histopathological evidence.
  • Disease in remission phase confirmed by clinical, endoscopic and histopathological evidence for at least 6 months
  • Diagnosis of disorders of gut-brain interaction (DGBI): IBS-D, IBS-M, bloating, and abdominal pain
  • Male/female
  • Age in the range 18-70 years
  • Subjects capable of conforming to the study protocol
  • Subjects who have given their free and

Exclusion criteria

Exclusion criteria:

  • History of gastrointestinal disorders or gastrointestinal surgery interfering with gastrointestinal function
  • Subjects with untreated food intolerance, i.e. remaining symptomatic despite the withdrawal of the suspected food
  • Currently following a restrictive diet (for example low FODMAPs diet or vegan diet)
  • Females of , in the absence of effective methods
  • Subjects who become unable to conform to protocol
  • Recent history or suspicion of alcohol abuse or drug addiction
  • Indication for the initiation of a new drug therapy during the study
  • History of current or recent antibiotic or probiotics use within the last 30 days
  • Subjects who are treated with antibiotics
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

What researchers measure

Primary outcomes

  1. Microbiota gut composition

    The primary endpoint will be the variation in gut microbiota analyzed through 16S rRNA gene sequencing from a fecal sample of patients presenting UC during remission phase and DGBI.

    Time frame: T=0 (baseline, before treatment), T=1 (after 60 days of treatment A or B), and T=3 (after an additional 60 days of treatment A or B).

Secondary outcomes

  1. Fecal calprotectin levels

    Concentration of fecal calprotectin measured in mg/Kg as an objective marker of intestinal inflammation. Normal value is \<250 mg/Kg, with higher values indicating active intestinal inflammation.

    Time frame: T=0 (baseline, before treatment), T=1 (after an additional 60 days of treatment A or B), and T=3 (after 60 days of treatment A or B)

  2. Quality of life in patiets with inflammatory bowel disease

    Quality of life will be assessed using the IBDQ (Inflammatory Bowel Disease Questionnaire). This is a 32-item questionnaire that evaluates symptoms and well-being over the prior two weeks using a 7-point scale from 1 (worst) to 7 (best). Total scores range from 32 to 224, with higher scores indicating a better quality of life.

    Time frame: T=0 (baseline, before treatment), T=1 (after 60 days of treatment A or B), and T=3 (after an additional 60 days of treatment A or B).

  3. Dietary habits

    Patients' dietary habits will be analysed using the WCRF questionnaire, which assesses dietary habits, particularly the questions focus on common eating patterns.

    Time frame: T=0 (baseline, before treatment) and T=3 (after taking both treatment A and treatment B)

  4. Gastrointestinal symptom severity in patients with Irritable Bowel Syndrome

    The severity of gastrointestinal symptoms will be assessed using IBS Symptom Severity Scale, which measures the intensity and frequency of abdominal pain, severity of abdominal distention, and dissatisfaction with bowel habits. Scores on the IBS-SSS range from 0 to 500 with higher scores indicating more severe symptoms.

    Time frame: T=0 (baseline, before treatment), T=1 (after 60 days of treatment A or B), and T=3 (after an additional 60 days of treatment A or B).

  5. Severity of gastrointestinal symptoms

    Severity of gastrointestinal symptoms will be assessed using the Visual Analog Scale (VAS) that measure for acute and chronic pain by making a handwritten mark on a 10-cm line (0 = "No Pain" to 100 = "Worst Imaginable Pain"). The patient marks a point on the line corresponding to their symptom intensity.

    Time frame: T=0 (baseline, before treatment), T=1 (after 60 days of treatment A or B), and T=3 (after an additional 60 days of treatment A or B).

  6. Severity of gastrointestinal symptoms

    Severity of gastrointestinal symptoms will be assessed using Bristol Stool Scale. This is a chart that rate the stools into seven categories based on form and consistency. Types 1,2 (constipation), types 3,4 (normal bowel function), types 5,6,7(diarrhea).

    Time frame: T=0 (baseline, before treatment), T=1 (after 60 days of treatment A or B), and T=3 (after an additional 60 days of treatment A or B).
