About this study

This pilot study will look at whether infusion of nutrients into the duodenum or into the stomach will result in:

  1. decrease in hunger and food intake
  2. greater weight loss due to loss of body fat with reductions in waist and hip circumferences
  3. improvements in other weight-related health conditions such as diabetes, high blood pressure, and high blood triglycerides. Inclusion criteria: 25-60 years old with a BMI of ≥ 30≤55 kg/m2.

Subjects (16 individuals) will be in the study for 12 days and have a dobhoff tube placed at the start of the study. Subjects will visit MCRU daily for 12 days where meals will be provided, and where anthropometric measures, blood work during an oral mixed meal tolerance test (study start and study end), and surveys will be completed. The dobhoff tube will remain in place until the end of the study.

Read the detailed description

The investigators propose a pilot study to evaluate whether mimicking rapid gastric emptying with duodenal infusion (DI) of nutrients (treatment) compared to gastric infusion (GI) of nutrients (control) over 12 days will result in 1) decrease in caloric intake 2) loss of body weight 3) improvements in comorbidities, particularly glucose metabolism, decrease in blood triglycerides and hypertension and increase in serum bile acids. Individuals eligible for the study will provide written informed consent. A comprehensive health and weight history will be obtained and physical exam obtained. Randomization will be 1:1 to DI vs. GI. There will be 8 individuals per treatment arm. A Dobhoff tube will be placed in each participant from nose either into duodenum (DI) or into stomach (GI). Participants will be allowed to eat three buffet style meals per day at 8.30 am, noon and 4 pm. The food intake will be noted for each meal by the investigators. Participants will note their feelings of hunger, fullness, bloating, nausea, and energy on a visual analogue scale every fifteen minutes for an hour starting at the initiation of the infusion. The placement of the tube (into stomach or duodenum) will be confirmed on day 1, day 6 and day 12 with radiographs. If necessary, fluoroscopy will be used only once during the study on day 1 to adjust the placement of the tube. During the study, the health of the participants will also be monitored and medications (if any) will be adjusted (if required) on a daily basis.

Intervention Group:

For first three days of the study (starting on Day#2), DI with 180 ml of warm saline will be given over 6 to 15 minutes through the Dobhoff tube starting a minute before initiation of each of the meal. For the remaining 7 days of the study, DI with nutrients in the form of 180 ml (266 Kcal) of warm Ensure Complete (Abbott Nutrition, OH) will be given over 6 to 15 minutes starting a minute before initiation of each meal. If they desire, participants will be allowed to eat a snack after the third meal.

Comparison group:

For first three days of the study (starting on Day#2), GI with 180 ml of warm saline will be given over 6 to 15 minutes through the Dobhoff tube starting a minute before initiation of each of the meal. For the remaining 7 days of the infusion part of the study, GI with nutrients in the form of 180 ml (266 Kcal) of warm Ensure Complete (Abbott Nutrition, OH) will be given over 6 to 15 minutes starting a minute before initiation of each meal. If they desire, participants will be allowed to eat a snack after the third meal.

Questions about this trial

What is this clinical trial studying?

A study testing Infusion in people with Obesity, run by University of Michigan 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 2 inclusion and 8 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 20 Dec 2018. 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 body weight (time frame: 12 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 20 Dec 2018.
