Could a cholesterol drug and vitamin ease thyroid eye disease?
NCT ID NCT07400757
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether taking a statin (atorvastatin) and vitamin D can calm inflammation and reduce eye bulging in people with active thyroid eye disease. 120 adults will be randomly assigned to standard care alone, statin plus standard care, vitamin D plus standard care, or both supplements plus standard care for 24 weeks. The goal is to see if these simple, low-cost treatments can improve disease activity and eye symptoms.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Atorvastatin (Lipitor) and vitamin D
- What this could lead to
- If it works, this could offer a simple, low-cost way to control active thyroid eye disease and reduce the need for stronger treatments.
- What could go wrong
- This is a small, early-phase trial (120 people) testing a repurposed drug and supplement. The effects may be modest or not better than standard care, and side effects like muscle pain or high blood sugar are possible.
