Effect of Prebiotics on the Gut Microbiome Profile and Beta Cell Function (NCT04114357) | Clinical Trial Compass

Effect of Prebiotics on the Gut Microbiome Profile and Beta Cell Function
United States12 participantsStarted 2020-06-22
Plain-language summary
Data suggest that intestinal microbiota might be critically involved both in autoimmunity and in glucose homeostasis. An acetylated and butyrylated form of high amylose maize starch (HAMS-AB) that increases beneficial short chain fatty acid (SCFA) production has been safe and effective in disease prevention in mouse type 1 diabetes (T1D) models. The objective of this application is to assess the effect of administering a prebiotic, such as HAMS- AB, on the gut microbiome profile, glycemia and β-cell function in humans with T1D.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Exclusion criteria
. Presence of severe, active disease that interferes with dietary intake or requires the use of chronic medication, except for well-controlled hypothyroidism and mild asthma not requiring oral steroids.
. Diabetes other than T1D (Known monogenic forms of diabetes, Type 2 diabetes)
. Chronic illness known to affect glucose metabolism (e.g. Cushing syndrome, polycystic ovarian disorder, cystic fibrosis) or taking medications that affect glucose metabolism (e.g. steroids, metformin)
. Psychiatric impairment or current use of anti-psychotic medication
. Any condition that, in the investigator's opinion, may compromise study participation or may confound the interpretation of the study results.
. Female participants of child-bearing age with reproductive potential, must not be pregnant and agree to use an effective form of birth control or be abstinent during the study period (see below)
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
