This study aims to show how digestive enzyme supplements help the body break down fats, proteins, and carbohydrates, especially after eating a high-fat, high-protein meal. Digestive enzymes are essential for nutrient absorption, but some people-such as those with certain medical conditions or high-protein diets-may not produce enough on their own. Poor digestion can lead to bloating, discomfort, and gut imbalances. This clinical trial tests a delayed-release, porcine-derived enzyme blend to see if it improves digestion and reduces symptoms like bloating and gas after eating a high-fat and high protein meal.

The carbohydrate inulin (from chicory root) is a healthy prebiotic ingredient found in dietary supplements and fortified foods (Nagy et al). Inulin is representative of a broader class of typically health-associated, yet fermentable carbohydrates called fructans that occur naturally in many vegetables, fruits, and wheat. Fructans, or long chains of fructose units, are resistant to human digestive enzyme hydrolysis and transit intact to the small intestine and colon where they undergo rapid fermentation by intestinal microbes. This microbial metabolism of fructans produces gas and other fermentation byproducts that can lead to excess gastrointestinal (GI) symptoms like abdominal bloating, cramping, stomach rumbling, and flatulence (Bonnema et al; Briet et al; Bruhwyler et al), especially in individuals with irritable bowel syndrome (Van den Houte et al). A new digestive enzyme called fructanase was developed to help with GI symptoms associated with fructan consumption. Positive findings from in vitro digestion simulations (Guice et al) and a first-in-human safety trial (Garvey et al) helped define the fructanase dose for this clinical trial-the primary objective of which is to investigate the effect of oral fructanase administration on GI symptoms in healthy adults after consuming oatmeal with added inulin (25 grams). Secondary outcomes include breath hydrogen and methane levels, which serve as biomarkers of intestinal microbial fermentation. The investigators hypothesize that fructanase administration will lower the severity of GI symptoms after inulin consumption, as well as lower breath biomarkers of intestinal microbial fermentation, compared to placebo.

Sub-optimal transfer of clinical information during inter-hospital transfer (IHT, the transfer of patients between acute care hospitals) is common and can lead to patient harm. To address this problem, the investigators will use key stakeholder input to refine and implement an interoperable health information exchange platform that integrates with the electronic health record and improves the reliability of and access to necessary clinical information in three use cases involving transfer of patients between sending and receiving hospitals with varying levels of affiliation and health record integration. The investigators will assess the effect of this intervention on frequency of medical errors, evaluate the use and usability of this platform from the perspective of those that interact with it, and use these results to develop a dissemination plan to spread implementation and use of this platform across other similar institutions.

The goal of this study is to determine the safety and efficacy of two enzyme cocktails in healthy adults with mild to moderate gastrointestinal discomfort. The main question aims to answer whether a 4-week administration of an enzyme cocktail can improve how the participant feels about their gut health. This is done by completing a weekly questionnaire, and the results are compared between the 4 weeks the participants are on a placebo and the 4 weeks the participants are on the enzyme cocktail. Participants will also provide a stool sample at the start and end of each treatment. Stool samples will collected and stored in case further microbiome analysis is warranted.

This clinical trial aims to understand the feasibility of patients taking ketone body supplement beta-hydroxybutyrate (BHB) for 4 weeks with a confirmed diagnosis of Crohn's disease and starting new therapy for active disease. The main questions it aims to answer are: * BHB supplementation will be feasible and acceptable to patients. * BHB supplementation will be associated with a reduction in systemic inflammation. * BHB supplementation will be associated with a reduction in pro-inflammatory bacterial colonies. Participants will: * Take 3 capsules x 3 times per day for 4 weeks. * Document food consumption using a 24-hour food recall questionnaire. * Provide blood and fecal samples twice, at the beginning of the study and the 4-week mark. Researchers will compare the group taking the ketone body supplement and the group not taking the supplement to see if the supplement provides relief of symptoms suffered from Crohn's disease.

A positive impact of a fermented dairy protein with prebiotic fiber supplement on self-reported GI complaints and wellbeing has been suggested (Wardenaar et al. 2024). The following project aims to further investigate the impact of this supplements in athletes with and without GI complaints in two separate data collections. Part I of the data collection aims to investigate the impact of this supplement vs. a placebo on carbohydrate malabsorption (as a potential cause for GI distress) in athletes that normally don't identify as having GI complaints (randomized double-blind cross over study design covering a total of 9 weeks, including a 3-week washout period). Part II of the data collection aims to confirm the earlier found results in the previous study (Wardenaar et al. 2024) in a group athletes self-reporting GI complaints that will be randomized into an intervention group or a placebo group (randomized double-blind parallel study design covering a total of 3 weeks).

Oat Fiber for Digestive Health

Los Angeles, California
The goal of this interventional study is to evaluate the tolerability and potential health benefits of oat fiber oligosaccharide (BG-OS) in healthy adults aged 18-70 years. The main questions it aims to answer are: * Does oat fiber dose impact gastrointestinal tolerability, as assessed by changes in symptoms using the Gastrointestinal Symptom Rating Scale (GSRS)? * Does oat fiber reduce postprandial glucose levels after a white rice challenge? Researchers will compare three groups receiving different doses of oat fiber (5 g, 10 g, and 20 g) to assess dose-related effects. Participants will: * Complete daily surveys on gastrointestinal symptoms, diet, energy, and sleep quality. * Use a continuous glucose monitoring device (CGM) to track glucose levels throughout the study. * Participate in standardized white rice challenge tests to measure glucose uptake during baseline and at one time point during study. * Provide stool samples during baseline and at the end of the study for gut microbiota analysis. * Undergo blood tests for biomarkers like CBC, CMP, and A1C at the beginning and end of the study.

"My orthopedist recommended a half replacement of my right knee. I have had both hips replaced. Currently have arthritis in knee, shoulder, and thumb. I want to avoid surgery, and I'm open-minded about trying a trial before using surgery as a last resort."

HZ
Arthritis PatientAge: 78

"I've been struggling with ADHD and anxiety since I was 9 years old. I'm currently 30. I really don't like how numb the medications make me feel. And especially now, that I've lost my grandma and my aunt 8 days apart, my anxiety has been even worse. So I'm trying to find something new."

FF
ADHD PatientAge: 31

"I've tried several different SSRIs over the past 23 years with no luck. Some of these new treatments seem interesting... haven't tried anything like them before. I really hope that one could work."

ZS
Depression PatientAge: 51

"I have dealt with voice and vocal fold issues related to paralysis for over 12 years. This problem has negatively impacted virtually every facet of my life. I am an otherwise healthy 48 year old married father of 3 living. My youngest daughter is 12 and has never heard my real voice. I am now having breathing issues related to the paralysis as well as trouble swallowing some liquids. In my research I have seen some recent trials focused on helping people like me."

Frequently Asked Questions

How much do Digestive Health clinical trials pay?

Each trial will compensate patients a different amount, but $50-100 for each visit is a fairly common range for Phase 2–4 trials (Phase 1 trials often pay substantially more). Further, most trials will cover the costs of a travel to-and-from the clinic.

How do Digestive Health clinical trials work?

After a researcher reviews your profile, they may choose to invite you in to a screening appointment, where they'll determine if you meet 100% of the eligibility requirements. If you do, you'll be sorted into one of the treatment groups, and receive your study drug. For some trials, there is a chance you'll receive a placebo. Across Digestive Health trials 30% of clinical trials have a placebo. Typically, you'll be required to check-in with the clinic every month or so. The average trial length for Digestive Health is 12 months.

How do I participate in a study as a "healthy volunteer"?

Not all studies recruit healthy volunteers: usually, Phase 1 studies do. Participating as a healthy volunteer means you will go to a research facility several times over a few days or weeks to receive a dose of either the test treatment or a "placebo," which is a harmless substance that helps researchers compare results. You will have routine tests during these visits, and you'll be compensated for your time and travel, with the number of appointments and details varying by study.

What does the "phase" of a clinical trial mean?

The phase of a trial reveals what stage the drug is in to get approval for a specific condition. Phase 1 trials are the trials to collect safety data in humans. Phase 2 trials are those where the drug has some data showing safety in humans, but where further human data is needed on drug effectiveness. Phase 3 trials are in the final step before approval. The drug already has data showing both safety and effectiveness. As a general rule, Phase 3 trials are more promising than Phase 2, and Phase 2 trials are more promising than phase 1.

Do I need to be insured to participate in a Digestive Health medical study?

Clinical trials are almost always free to participants, and so do not require insurance. The only exception here are trials focused on cancer, because only a small part of the typical treatment plan is actually experimental. For these cancer trials, participants typically need insurance to cover all the non-experimental components.

What are the newest Digestive Health clinical trials?

Most recently, we added Digestive Enzymes for Indigestion, Fermented Dairy Protein for Digestive Health and Oat Fiber for Digestive Health to the Power online platform.
