Using Exhaled Air to Determine Changes in Nutritional Status of Patients on Intravenous Nutrition
NCT02843256 · View on ClinicalTrials.gov ↗
Study Summary
Carbon-12 and carbon-13 are naturally-occurring isotopes that are found in exhaled breath. Investigators have proved that the 13CO2/12CO2 breath delta value (BDV) changes in subjects who were in negative energy balance then fed a positive energy balance meal. Measuring one liter of exhaled breath daily may be a more convenient way to measure negative or positive energy balance in patients receiving intravenous nutrition.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT02843256
The ClinicalTrials.gov registry entry for NCT02843256 describes a study currently listed as completed. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 20 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of Wisconsin, Madison, which has 943 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 3 conditions, with Obesity appearing as the primary indexed condition, and to 1 intervention — of which Isomark Canary is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT02843256 reports 1 study location spanning 1 distinct geographic area — top geographies include Wisconsin. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll. Verify current status, eligibility criteria, and contact details directly at ClinicalTrials.gov, and discuss any participation decision with your own healthcare provider.
