What is being measured

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

  1. Composition of Stool Micro Biome Diversity and Phylogenetic Distribution at 0 Days, 8 Days and 28 Days

    Relative abundance is defined as the proportion of total identified bacteria in a sample that are a given type of bacteria. As an example a relative abundance of firmicutes equal to 0.9 would mean that 90% of the bacteria identified in a sample are firmicutes

    Measured: Baseline, Day 8, Day 28

  2. Laboratory Parameters at Day 0, Day 8 and 28 Calcium, Bilirubin, Glucose, Blood Urea Nitrogen, Creatinine

    Measured: Baseline, Day 8, Day 28

  3. Indirect Calorimetry Data at 0 Day, 8 Days and 28 Days Volume of Oxygen and Volume Carbon Dioxide

    Measured: Baseline, Day 8, Day 28

  4. Indirect Calorimetry Data at 0 Day, 8 Days and 28 Days Respiratory Quotient RQ

    The respiratory quotient is a ratio between the volume of carbon dioxide exhaled and the volume of oxygen inhaled during respiration. It typically ranges between 0.7 and 1.0 and is an indicator of metabolic fuel or substrate use in tissues; it must be calculated under resting or steady-state exercise conditions. A ratio of 0.7 is indicative of mixed fat use, whereas a ratio of 1.0 indicates the exclusive use of carbohydrates

    Measured: Baseline, Day 8, Day 28

  5. Fecal Intestinal Antimicrobial Peptide Secretion at 0 Days, 8 Days and 28 Days Total Protein

    Measured: Baseline, Day 8, Day 28

  6. Fecal Intestinal Antimicrobial Peptide Secretion at 0 Days, 8 Days and 28 Days Normalized Calprotectin and Human Beta-Defensin2

    Measured: Baseline, Day 8, Day 28

  7. Serum Indicators of Intestinal Permeability at 0 Days, 8 Days and 28 Days Serum Lipopolysaccharide, Hyaluronan

    Measured: Baseline, Day 8, Day 28

  8. Serum Indicators of Inflammation and Injury at Baseline, 8 Days and 28 Days-tumor Necrosis Factor (TNF) Alpha, Interleukin 6 (IL-6)

    Measured: Baseline, Day 8, Day 28

  9. Baseline Serum Indicators of Inflammation and Injury at Baseline, 8 Days and 28 Days-C-reactive Protein

    Measured: Baseline, Day 8, Day 28

  10. Blood Protein, Hemoglobin and Albumin Levels at Baseline, Day 8, and Day 28

    Measured: Baseline, day 8 day 28

  11. White Blood Cell and Platelet Count at Baseline, Day 8, and Day 28

    Measured: baseline, day 8, and day 28

  12. Alkaline Phosphatase, Alanine Transaminase , and Aspartate Transaminase at Baseline, Day 8, and Day 28

    Measured: baseline, day 8, and day 28

  13. Serum Sodium, Potassium, and Carbon Dioxide at Baseline Day 8 and Day 28

    Measured: baseline, day 8, and day 28

  14. Resting Energy Expenditure (REE) and Metabolic Rate at Baseline Day 8 an Day 28

    Measured: Baseline, day 8, and day 28

  15. Resting Energy Expenditure as a Percent of Predicted at Baseline, Day 8, and Day 28

    This values measures the amount of energy a person uses during rest and compares it the average expected number of someone who is the same gender, age, and race.

    Measured: Baseline, day 8, and day 28

Questions about this trial

What is this clinical trial studying?

A study testing Hyaluronan in people with Gastrointestinal Microbiome, run by The Cleveland Clinic 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 13 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 3 Sep 2020. 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?

Yes. Results are posted in the registry (first posted 13 Aug 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Composition of Stool Micro Biome Diversity and Phylogenetic Distribution at 0 Days, 8 Days and 28 Days (time frame: Baseline, Day 8, Day 28). The study lists 15 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 NCT02867605, which also lists 2 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 3 Sep 2020.
