What this trial studies

This study evaluates the efficacy and safety of secukinumab, administered subcutaneously at a dose of 300 mg, in patients with new onset giant cell arteritis (GCA) who are in clinical remission. Participants will receive either secukinumab or a placebo, both in combination with a glucocorticoid taper regimen. The study aims to assess the therapeutic benefit of targeting the IL-17 pathway in GCA, based on previous findings linking IL-17A to the disease's inflammatory processes. The results will support health technology assessments for secukinumab in Germany.

Who should consider this trial

Good fit: Ideal candidates are adults aged 50 and older with a recent diagnosis of new-onset giant cell arteritis.

Not a fit: Patients with chronic giant cell arteritis or those not in clinical remission may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with giant cell arteritis, potentially improving their quality of life and disease management.

How similar studies have performed: Other studies targeting the IL-17 pathway have shown promise in treating similar inflammatory conditions, suggesting potential success for this approach in GCA.

Exclusion Criteria:

Participants meeting any of the following criteria are not eligible for inclusion in this study.

3. Participants not eligible for glucocorticoid monotherapy due to known increased risk for or presence of GC-related adverse-effects or complications and/or intolerance to GCs, such as osteoporosis, diabetes mellitus, cardiovascular disease and glaucoma as assessed at the investigator's discretion (see Appendix 15.2).

4. Previous exposure to secukinumab or another biologic drug directly targeting IL-17 or IL-17 receptor.

5. Participants treated with any cell-depleting therapies including but not limited to anti- CD20 or investigational agents (e.g., anti-CD3, anti-CD4, anti-CD5 or anti-CD19).

6. Previous participation in clinical trials for GCA 7. Participants who have been treated with inhibitors directly targeting IL-12 and/or IL-23 (such as ustekinumab, guselkumab, tildrakizumab, risankizumab), IL-1 or IL-1 receptor (such as anakinra or canakinumab), or abatacept within 4 weeks or within 5 half-lives of the drug (whichever is longer) prior to BSL.

8. Treatment with tocilizumab, other IL-6/IL6-R inhibitor or JAK inhibitor within 12 weeks or within 5 half-lives of the drug (whichever is longer) prior to BSL, or if participant did not respond to or experienced a clinical relapse during treatment any time before BSL.

9. Any treatment received for GCA other than GCs and participant did not respond to treatment or experienced a clinical relapse during treatment any time before BSL.

10. Any other biologics within 4 weeks or within 5 half-lives of the drug (whichever is longer) prior to BSL.

11. Participants treated with i.v. immunoglobulins or plasmapheresis within 8 weeks prior to BSL.

12. Participants treated with cyclophosphamide, tacrolimus, everolimus hydroxychloroquine, cyclosporine A, azathioprine, sulfasalazine, mycophenolate mofetil within 6 months prior to BSL.

13. Participants treated with methotrexate (MTX), within 4 weeks prior to BSL. 14. Participants treated with leflunomide within 8 weeks prior to BSL unless a cholestyramine washout has been performed in which case the participant must be treated within 4 weeks of BSL.

22. Active ongoing diseases which in the opinion of the investigator immunocompromises the participant and/or places the participant at unacceptable risk for treatment with immunomodulatory therapy.

23. Active ongoing inflammatory diseases or underlying metabolic, hematologic, renal, hepatic, pulmonary, neurologic, endocrine, cardiac, infectious or gastrointestinal conditions, which in the opinion of the investigator immunocomprises the participant and/or places the participant at unacceptable risk for participation in an immunomodulatory therapy.

24. Major ischemic event (e.g., myocardial infarction, stroke, etc.) or transient ischemic attack (TIA) (except ischemia-related vision loss), related or unrelated to GCA, within 12 weeks of screening.

If presence of latent tuberculosis is established, then treatment according to local country guidelines must be initiated prior to BSL.
