Cystinuria drug trial pulled before it even started

NCT ID NCT04147871

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study was designed to test whether ADV7103, a combination of potassium citrate and potassium bicarbonate, could help people with cystinuria by making their urine less acidic. The goal was to see if it could raise urine pH to 7.0 or higher, which might reduce kidney stone formation. However, the trial was withdrawn before enrolling any participants, so no data were collected.

What this could mean

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

Active substance

ADV7103 (a mix of potassium citrate and potassium bicarbonate)

What this could lead to

If it had worked, this could have pointed toward a better way to manage cystinuria by controlling urine acidity to prevent kidney stones.

What could go wrong

The trial was withdrawn before enrolling anyone, so no results are available. Even if run, it was an early-stage study with a short 7-day treatment period, so long-term benefits and safety would remain uncertain.
