Summary

This study tests a new device that uses a sensor placed on the chest to measure kidney function in 15 adults with heart failure. Participants receive an injection of a fluorescent dye (Relmapirazin) and a standard contrast agent (iohexol), then the sensor tracks how quickly the dye clears from the skin. Researchers compare these readings to traditional blood tests to see if the sensor is accurate enough for routine use.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Relmapirazin (Lumitrace) injection and iohexol

What this could lead to

If successful, this could provide a simpler, less invasive way to monitor kidney function in heart failure patients, reducing the need for repeated blood draws.

What could go wrong

This is a very small, early study with only 15 participants, so results may not apply to everyone. The sensor's accuracy may not meet the target, and it is not a treatment.
