About this study
Time-restricted feeding (TRF) is a dietary regimen involving the consumption of food and liquids within a defined time window with or without additional restriction on dietary composition. TRF has been associated with improvements in inflammation, host metabolism, autophagy, gut microbial composition, and gut permeability. Crohn's disease is an inflammatory bowel disease of unknown etiology that likely results from a combination of genetic and environmental factors. This proposed study will test the hypothesis that a time-restricted feeding regimen will improve clinical outcomes and favorably influence the gut microbiome in patients with active Crohn's disease. If time-restricted fasting proves beneficial to this patient population then it will pave the way for larger, prospective studies and clinical trials.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Time Restricted FeedingOther
Also called Intermittent Fasting
The counseling on the regimen will involve instructing the subjects on study compliance and fasting times. Subjects will be instructed to choose an eight-hour eating window (e.g., 11:00am - 7:00pm) during which the patient will be able to eat his/her normal diet. During the 16-hour fasting window (e.g., 7:00pm - 11:00am), the participant will be able to drink regular water and black coffee.
| Study group | Role | What they receive |
|---|---|---|
| Time Restricted Feeding | Experimental | Subjects will be required to fast for 16 consecutive hours daily for 4 weeks. The registered dietitian will provide subjects counseling on the intermittent fasting regimen. Receives: Other: Time Restricted Feeding |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in patient reported outcomes as measured by Patient Recorded Outcome 2 (PRO2) scores.
This will be measured to assess clinical response as determined by a reduction of either 8 or more points or a total PRO2 score of less than or equal to 8 points. The PRO2 score scale ranges from a score of 0 as the minimum and has no maximum limit. A score below 8 is considered remission; a score less than 14 is considered mild; and a score greater than 34 is considered severe.
Measured: Baseline (Week 0); 4 weeks after incorporating time restricted feeding into diet
Change in Inflammatory Markers as measured by blood C-reactive protein (CRP).
This will be measured to assess clinical response as determined by a reduction of 50% or more from baseline or normalization of the CRP level results.
Measured: Baseline (Week 0); 4 weeks after incorporating time restricted feeding into diet
Change in inflammatory markers as measured by fecal calprotectin lab results
This will be measured to assess clinical changes as determined by a reduction of 50% or more from baseline or normalization of the calprotectin levels results.
Measured: Baseline (Week 0); 4 weeks after incorporating time restricted feeding into diet
Secondary outcomes (2)
Change in taxonomic composition of the gut microbiome as measured by Polymerase Chain Reaction (PCR) analysis.
This will be measured to assess the impact of time restricted feeding on intestinal microbiota composition.
Measured: Baseline (Week 0); 4 weeks after incorporating time restricted feeding into diet
Markers of systemic peripheral blood immunity as measured by Mass Cytometry by Time-Of-Flight (CyTOF) analysis.
This will be measured to assess the effect of time restricted feeding on immune cell composition.
Measured: Baseline (Week 0); 4 weeks after incorporating time restricted feeding into diet

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Time-restricted feeding (TRF) is a dietary regimen involving the consumption of food and liquids within a defined time window with or without additional restriction on dietary composition. TRF has been associated with improvements in inflammation, host metabolism, autophagy, gut microbial composition, and gut permeability. Crohn's disease is an inflammatory bowel disease of unknown etiology that likely results from a combination of genetic and environmental factors. This proposed study will test the hypothesis that a time-restricted feeding regimen will improve clinical outcomes and favorably influence the gut microbiome in patients with active Crohn's disease. If time-restricted fasting proves beneficial to this patient population then it will pave the way for larger, prospective studies and clinical trials.

Questions about this trial
What is this clinical trial studying?
A study testing Time Restricted Feeding in people with Crohn's Disease (CD), run by Weill Medical College of Cornell University at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 31 Jan 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in patient reported outcomes as measured by Patient Recorded Outcome 2 (PRO2) scores. (time frame: Baseline (Week 0); 4 weeks after incorporating time restricted feeding into diet). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04271748, which also lists 8 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Jan 2023.
