Can a breathing test personalize nutrition for cancer patients?
NCT ID NCT07776704
First seen Aug 20, 2026 · Last updated Aug 21, 2026 · Updated 1 time
Summary
This trial asks whether using a device that measures a person's actual energy needs (indirect calorimetry) is a better way to prescribe parenteral nutrition—liquid food given through a vein—for adults with cancer who cannot eat enough by mouth. Half of the participants will have their nutrition dose based on this measured energy expenditure, while the other half will receive a standard dose based on body weight. The study will see if the measuring approach is practical and acceptable to patients over an 8-week period.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Indirect calorimetry (a device that measures energy expenditure) and weight-based parenteral nutrition dosing
- What this could lead to
- If successful, this could lead to more personalized and accurate nutrition dosing for cancer patients who cannot eat normally, potentially improving their nutritional status and overall well-being.
- What could go wrong
- This is a small, early-stage feasibility study, so results may not be conclusive. The indirect calorimetry device may be uncomfortable or impractical for some patients, and the study does not yet measure long-term outcomes.
