Tracking inflammatory orbitopathy progression in people receiving second-line treatments

Official title: Treatment of Graves' Orbitopathy in Patients Failing Corticosteroid Therapy: Multicenter National Retrospective Study- Basedow

Run by Centre Hospitalier National d'Ophtalmologie des Quinze-Vingts · NCT07117981 · Data updated 2026-11-12

This project follows adults with moderate-to-severe Graves' orbitopathy who are receiving second-line treatments (immunosuppressants, radiotherapy, or biologics) to see how their eye inflammation and blood markers change over time.

Is this trial a fit for you?

Likely a good fit

Adults (≥18) with moderate-to-severe Graves' orbitopathy who are corticosteroid-resistant or -dependent, have CAS ≥3 (or CAS <3 with moderate-to-severe disease per EUGOGO), and are receiving immunotherapy, biologics, or radiotherapy are ideal candidates.

Probably not a fit

Patients who have had orbital bone or fat decompression, those with severe corneal involvement or optic neuropathy, or those not receiving second-line therapies are unlikely to benefit or qualify for this study.

What this trial studies

This observational study follows adults with moderate to severe Basedow (Graves') orbitopathy who are treated with second-line therapies including immunosuppressants, radiotherapy, or biologic agents. Clinical activity scores (CAS), imaging data, and biological markers will be collected longitudinally to document clinical and biological progression. Eligible patients are corticosteroid-resistant or corticosteroid-dependent and are managed at participating French centers; patients with prior orbital decompression or severe corneal/optic nerve involvement are excluded. The study does not assign treatments but records real-world management and requires patient consent for reuse of health data.

Why it matters

Potential benefit: If successful, the results could help clinicians better time and choose second-line therapies and identify biological markers that predict who will improve.

How similar studies have gone: Some targeted biologic trials (for example teprotumumab) have shown clear clinical benefits in Graves' orbitopathy, but comparative real-world data on biological marker changes across varied second-line treatments remain limited.

* Patients with a CAS ≥ 3 or CAS \<3 with moderate to severe orbitopathy (according to EUGOGO);
* Patients treated with immunotherapy, biotherapy, or radiotherapy as second-line treatment;

* Patients with severe corneal involvement (Grade B or C; NO SPECS classification);
* Patients with optic neuropathy (Grade B and C; NO SPECS classification);
* Patients who have received 1 gram corticosteroid boluses for dysthyroid orbitopathy;
