Trial summary

The purpose of this study is to see whether hematopoietic stem cell transplant (HSCT) patients can consistently eat a diet rich in prebiotics. This type of diet may be helpful in maintaining diversity in the gastrointestinal (GI) system and therefore potentially decreasing risk of other GI problems. Read more about this study

About this study

Official title: Effects of Prebiotics on Gut Microbiome in Patients Undergoing Stem Cell Transplants

The purpose of this study is to see whether hematopoietic stem cell transplant (HSCT) patients can consistently eat a diet rich in prebiotics. This type of diet may be helpful in maintaining diversity in the gastrointestinal (GI) system and therefore potentially decreasing risk of other GI problems.

Read the detailed description

Maintaining gastrointestinal (GI) microbiome diversity has been shown to improve treatment related mortality in HSCT patients. Interventions to improve GI microbial diversity could be beneficial to this patient population. Diets rich in prebiotics have been shown to increase gut microbial diversity and improve symptoms in other gastrointestinal diseases. Prebiotics are non-digestible carbohydrates that promote growth of commensal organisms in the gut by providing nutrition. Some examples are brown rice, green apples, and tomatoes. Our theory is that consuming a diet rich in prebiotics pre- and during the first 100 days following HSCT will help to reduce acute graft versus host disease (aGVHD) overall, and specifically acute GI GVHD, and clostridium difficile (C.Diff). Participants will be encouraged to eat at least 2 servings of a prebiotic-rich food from time of admission for HSCT through 100 days following HSCT and will be clinically monitored, including for acute GVHD, acute GI GVHD and C.Diff. Stool samples will be collected from all participants about once every 4 weeks.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Frequency of participants ingesting the required diet

    Frequency of participants reporting ingesting at least 2 servings of prebiotics on ≥ 80% of study days

    Measured: From initiation of conditioning regimen for HSCT through 100 days following HSCT

Secondary outcomes (4)
  1. Incidence and severity of acute GVHD (aGVHD) and acute GI GVHD

    Stage and grade of aGVHD (allogeneic HSCT participants only)

    Measured: Within the first 100 days following HSCT

  2. Incidence of CDiff infection

    Number of people diagnosed with CDiff during the time frame

    Measured: Within the first 100 days following HSCT

  3. Patient weight

    Measured: From initiation of conditioning regimen for HSCT through 100 days following HSCT

  4. Number of days to neutrophil engraftment

    Absolute neutrophil count >1000 for 1 day or > 500 for 3 consecutive days

    Measured: From initiation of conditioning regimen for HSCT through 100 days following HSCT

Questions about this trial

What is this clinical trial studying?

A study testing Pre-biotic foods/drinks in people with Multiple Myeloma and Acute Myeloid Leukemia, run by University of Virginia 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 8 inclusion and 3 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 4 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?

Frequency of participants ingesting the required diet (time frame: From initiation of conditioning regimen for HSCT through 100 days following HSCT). 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 4 Jan 2023.
