Kidney cancer trial pulled before it even started

NCT ID NCT05487859

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study planned to test whether adding acarbose, a drug normally used for diabetes, could improve standard immunotherapy for advanced kidney cancer. The goal was to see if the combination was safe and affected gut bacteria. However, the trial was withdrawn before enrolling any participants, so no results are available.

What this could mean

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

Active substance

Acarbose (a diabetes drug that may affect the immune system)

What this could lead to

If it had worked, this could have pointed toward a new way to boost standard immunotherapy for advanced kidney cancer.

What could go wrong

The trial was withdrawn before any patients enrolled, so we have no data on safety or effectiveness. Acarbose is not a standard cancer treatment, and its benefits in this setting are entirely unknown.
