A Study Evaluating the Impact of Regular FODMAP-targeting Digestive Enzyme Blend Use on Gastrointestinal Symptoms in Individuals With Self-Reported Bloating

What this study is about

This study is a randomly assigned, where neither patients nor doctors know which treatment is given, compared against an inactive treatment, within-individual crossover trial designed to assess the impact of regular use of a consumer-grade FODMAP-targeting digestive enzyme blend (FODZYME®) on gastrointestinal symptoms in adults with self-reported bloating.

View original scientific description

This study is a randomized, double-blind, placebo-controlled, within-individual crossover trial designed to assess the impact of regular use of a consumer-grade FODMAP-targeting digestive enzyme blend (FODZYME®) on gastrointestinal symptoms in adults with self-reported bloating.1 The study's rationale is based on the fact that fermentable carbohydrates (FODMAPs) are often poorly absorbed and can trigger symptoms like bloating and abdominal pain. While a Low FODMAP Diet (LFD) is clinically validated for symptom relief, it is restrictive. The enzyme blend is intended to offer a more flexible, enzyme-based solution by targeting and breaking down FODMAPs, such as fructan, GOS, and lactose, before they ferment in the colon. The primary objective is to evaluate the product's impact on bloating symptoms, measured by the mean PROMIS scale Gastrointestinal Gas and Bloating score. Secondary and exploratory objectives include assessing the impact on overall gastrointestinal symptom severity (IBS-SSS), abdominal pain (PROMIS Belly Pain score), food-related quality of life (FR-QoL-29), and anxiety (GAD-7 scores). The study also aims to evaluate these effects across various Irritable Bowel Syndrome (IBS) subgroups (IBS-C, IBS-D, IBS-M). The trial is a consumer-driven, decentralized research study utilizing validated patient-reported outcome measures that can be completed in a home setting.

Who can participate

This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.

Inclusion criteria

  • Individuals aged 18 years old or older
  • Screening score of \>= 55 on the PROMIS Scale v1.1 - Gastrointestinal Gas and Bloating 13a scale.
  • Screening severity score of \>= 55 on the PROMIS Scale v1.0 - Gastrointestinal Belly Pain scale.
  • Screening score of \<10 on the Generalized Anxiety Disorder 7-item (GAD-7) scale
  • Adults with or without IBS are eligible; participants with IBS experiencing symptoms must meet the Rome IV criteria as determined by the Rome IV Diagnostic Questionnaire (R4DQ) IBS Module.
  • Able to maintain 80% compliance with daily questionnaires during the 2 week run-in period.
  • In good general health at the time of screening (Investigator discretion).
  • Able to read and understand English and provide informed consent.
  • Able to use a personal smartphone device and download Chloe by People Science.
  • Able to receive shipment of the product at an address within the United States.
  • Able to complete study assessments over the course of up to 19 weeks.

Exclusion criteria

  • Do not have a personal smartphone, internet access, or unwilling to download Chloe.
  • Concomitant Therapies: Participants receiving any of the following treatments or therapies are excluded:
  • Any investigational therapies or treatments (pharmaceuticals, devices, supplements) within 30 days prior to randomization.
  • Ongoing psychological therapies specifically targeting gastrointestinal symptoms or functional disorders, including but not limited to GI-directed Cognitive Behavioral Therapy (CBT), GI hypnotherapy, or other therapies for Disorders of Gut-Brain Interaction (DGBI).
  • Treatment with Glucagon-like peptide-1 (GLP-1) agonists (e.g., semaglutide, tirzepatide) within the last 90 days prior to randomization, due to their known effects on gut motility and GI symptoms.
  • Current or recent (within the last 6 months) chemotherapy or immunotherapy for cancer treatment.
  • Current or planned use of any other digestive enzymes prescription or over-the-counter (OTC).
  • Chronic use (defined as daily use for \>30 days within the last 90 days) of any medication known to have substantial gastrointestinal side effects (e.g., diarrhea, constipation, nausea) that, in the opinion of the Principal Investigator, may confound the assessment of study outcomes. This may include high-dose NSAIDs, opioids, prokinetics, bile acid binders, or certain antibiotics.
  • Variable use of probiotics, fiber supplements, laxatives, stool softeners, antidiarrheals (if taking) in the last 30 days. Variable use is defined as use of any probiotic, fiber supplement, laxative, stool softener, or antidiarrheal with a dose change greater than 50% in the last 30 days or initiation or discontinuation of a gut-active product in the last 30 days.
  • Other Illnesses or Conditions: Participants who have the following comorbidities or gastrointestinal illnesses are excluded:
  • Currently diagnosed with Alcohol Use Disorder and/or Substance Use Disorder
  • Currently pregnant, planning to become pregnant in the next 4 months, or breastfeeding
  • History of bariatric or other significant gastrointestinal surgery (e.g., small bowel resection, total colectomy) that has permanently altered GI anatomy or function. Standard appendectomy or cholecystectomy are generally permitted. Any underlying medical conditions or comorbidities that may confound the assessment of digestive symptoms or the evaluation of the study outcomes (e.g., Type I diabetes, Endometriosis, etc.).
  • Acute gastroenteritis within the past 4 weeks;
  • New diagnosis workup planned during study that may change diagnosis/ behavior/ medications (eg. colonoscopy prep or major bowel cleanse, upcoming GI consult that could affect eligibility).
  • Have a significant illness, disease or condition which, in the opinion of the principal investigator, may impact their ability to participate in the study or impact the study outcomes.
  • Self-reported known hypersensitivity or previous allergic reaction to corn and/or any previous reaction to digestive enzyme supplements (eg. Beano and Lactaid)
  • Comorbid GI conditions: IBD - Ulcerative Colitis or Crohn's Disease, Microscopic Colitis, history of small bowel or colonic surgeries, Celiac disease, or Bile Acid Malabsorption (BAM).
  • Screening score of ≥10 on the Generalized Anxiety Disorder 7-item (GAD-7) scale
  • On a low FODMAP diet based on FODMAP FFQ results at Screening
  • History of following a low FODMAP diet in the past 6 months (self-reported)
  • Any history of following LFD (Low FODMAP Diet) with no response (i.e. failed LFD in past)
  • Participants who are on or plan to initiate a major restrictive or elimination diet, or a structured weight-loss diet, during the study period.
  • No planned changes in diet, lifestyle or medications for IBS during study period.
  • Use of any antibiotics, antifungals, or antivirals within 2 weeks prior to randomization.
  • Participants planning extended travel that would interfere with compliance or study procedures.
  • Are unlikely for any reason to be able to comply with the trial or considered unsuited for participation in the study by the Principal Investigator.

Frequently asked questions

What is a clinical trial?

A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.

Is it safe to participate?

Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.

Will I be compensated?

Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.

Will I receive a placebo instead of treatment?

When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.

Can I leave a trial if I change my mind?

Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.

How long does a clinical trial last?

Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
