Could a common blood pressure drug shrink kidney tumors?
NCT ID NCT02104011
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This pilot study tested whether propranolol, a beta-blocker, could shrink or stabilize kidney angiomyolipomas in people with tuberous sclerosis. Only 2 participants were enrolled before the trial was terminated, so the results are very limited. The goal was to find a less invasive alternative to surgery or embolization.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Propranolol (a beta-blocker, commonly used for high blood pressure)
- What this could lead to
- If it works, this could point toward a non-invasive treatment option for kidney tumors in tuberous sclerosis, potentially avoiding surgery or embolization.
- What could go wrong
- This was a very small pilot trial with only 2 participants and was terminated early, so results are not reliable. Beta-blockers may not shrink these tumors, and side effects like low blood pressure or fatigue are possible.
