Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

 NCT04180904
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

The study asks if dietary change and nutritional support improves disease activity and if patients are better able to improve or sustain progress with additional incentives. The study will use an online program to communicate with participants through text and online surveys. This 24-week trial will enroll 90 patients in the US and Canada with New York University as a back-up site.

Arms & Interventions

Arms

Active Comparator: Diet 1

Diet 1 will focus on the dietary pattern and monitor types of foods, supplementary nutrition, and provide nutritional support with a dietitian.

Active Comparator: Diet 2

Diet 2 will focus on the dietary pattern and monitor the amount of food, complimentary nutrition, and nutritional support with a dietitian.

No Intervention: Diet 3

Diet 3 will focus on healthy dietary patterns and provide nutritional support with a dietitian.

Interventions

Other: - Diet 1

Diet 1 will focus on which foods are eaten and the impact on disease outcomes.

Other: - Diet 2

This diet will limit the amount of food energy consumed each day and the impact on disease outcomes. This will be determined by factors including the subject's demographics (age, sex, weight, height).
