Could a common cholesterol drug shrink uterine fibroids?

NCT ID NCT03400826

First seen Jul 21, 2026 · Last updated Jul 22, 2026 · Updated 1 time

Summary

This phase II trial tests whether simvastatin, a widely used cholesterol medication, can reduce the size of uterine fibroids and ease related symptoms. Researchers will give 60 women either simvastatin or a placebo daily for 12 weeks, measuring fibroid volume by ultrasound and tracking symptom changes with a validated questionnaire. The goal is to find a simple, drug-based alternative to surgery for fibroids.

What this could mean

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

Active substance
simvastatin 40 mg daily for 12 weeks
What this could lead to
If it works, this could point toward a non-surgical treatment for uterine fibroids using a common, low-cost drug.
What could go wrong
This is a small, early-phase trial with only 60 participants. The drug may not shrink fibroids or improve symptoms, and simvastatin has known side effects like muscle pain.
