Study of Atorvastatin and Its Effects in Clinical and Radiological Aspects in Patients With Moderate-to-Severe Thyroid Eye Disease (SEMAR-TED)

August 7, 2026 updated by: Banu Aji Dibyasakti

Adjunctive Atorvastatin in Moderate-to-severe Thyroid Eye Disease (SEMAR-TED: Structural, Biomarker Expression and Muscle Endpoints of Atorvastatin): Study Protocol for a Randomised, Open-label, Assessor-masked Controlled Trial

The trial tests the hypothesis that, in adults with active, moderate-to-severe Graves' orbitopathy, 24 weeks of oral atorvastatin 20 mg daily added to a standard 12-week course of intravenous methylprednisolone produces a greater reduction in extraocular muscle size than intravenous methylprednisolone alone, and that any such reduction is accompanied by lower expression of TSH receptor, IGF-1 receptor, PDGF receptor, PI3K/AKT and miR-155 transcripts, and higher expression of miR-146a. The prespecified direction for miR-146a follows its reported suppression in CD4+ T cells in active disease [26]. Reported directions of change are compartment-specific and not unanimous, so the transcript analyses are exploratory.

  • For women of childbearing potential, agreement to use effective contraception until week 24

Exclusion Criteria:

  • Sight-threatening disease at screening: dysthyroid optic neuropathy or corneal breakdown
  • Any other autoimmune disease requiring systemic immunosuppresion

  • Current or recent (within 3 months) use of any lipid-lowering drug
  • Any contraindication to orbital decompression
  • Any independent indication for lipid-lowering therapy: established atherosclerotic cardiovascular disease, more than one cardiovascular risk factor (diabetes mellitus, hypertension, obesity), or LDL cholesterol ≥ 190 mg/dL
  • Systemic glucocorticoid or immunosuppressive treatment for orbitopathy within the preceding 3 months
  • Previous orbital irradiation or orbital surgery
  • Alanine or aspartate aminotransferase > 3 × upper limit of normal, or creatine kinase > 5 × upper limit of normal, at screening
  • Estimated glomerular filtration rate < 30 mL/min/1.73 m²
  • Pregnancy at screening (confirmed by a negative test before randomisation) or breastfeeding
  • Concomitant treatment with a strong CYP3A4 inhibitor
  • Any condition that, in the opinion of the investigator, would prevent completion of the trial

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Individual rectus muscle diameters
Time Frame: At the first week,12th week, and 24th week from starting point of treatment
The primary outcome is measuring the rectus muscle diameters using Coronal CT, per muscle, both orbits
At the first week,12th week, and 24th week from starting point of treatment

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Composite ocular response
Time Frame: At Week 24th

A participant is a responder if at least two of the five criteria below are met in the more affected eye, with no deterioration in any of them in either eye:

  1. reduction in clinical activity score of 2 points or more;
  2. reduction in proptosis of 2 mm or more, without an increase of 2 mm or more in the fellow eye;
  3. reduction in vertical palpebral fissure height of 2 mm or more, with the same proviso for the fellow eye;
  4. disappearance of diplopia, or improvement by at least one Gorman grade;
  5. improvement in best-corrected visual acuity of 0.1 logMAR or more, this being the step on the logMAR chart closest to the 0.2-decimal criterion used in STAGO.
