Brief summary: The purpose of this study is to demonstrate the efficacy and safety of subcutaneously (s.c.) administered secukinumab 300 mg in combination with glucocorticoid taper regimen compared to placebo in combination with glucocorticoid taper regimen, in adult patients with new onset of giant cell arteritis (GCA) who are in clinical remission and who are eligible for treatment with glucocorticoid-monotherapy as per current clinical practice and treatment guidelines for the targeted participant population, thereby supporting health technology assessments (HTAs) of secukinumab in Germany.

Detailed description: Recent scientific evidence identified an association between polymorphisms within the IL-17A locus and GCA, supporting a role for IL-17A in vasculitis pathophysiology. Analysis of the inflammatory processes in the aortic wall has indicated that inflammatory cytokines, such as IL-6 and IL-17A are involved in GCA pathogenesis. Elevated IL-17A mRNA levels are correlated with IL-6 and IL-23p19 mRNA levels indicating the involvement of the IL-23/Th17 axis in GCA. With its pleiotropic activity on many different cell types, IL-17A may actively contribute to the inflammatory processes in GCA. In addition, animal studies also support a role of IL-17A as a driver of vasculitis, since mice deficient in IRF-4 binding protein, which have increased IL-21 and IL-17A expression, spontaneously develop arthritis-like joint disease and large vessel vasculitis (LVV).

As secukinumab has already demonstrated a positive benefit/risk profile in the treatment of multiple chronic inflammatory diseases, including PsO, PsA and axSpA, and based on the scientific rationale for targeting the IL-17 pathway in GCA as well as on the basis of the currently ongoing Phase 2 Proof-of-Concept trial the which evaluates the efficacy, safety and tolerability of 300 mg secukinumab compared to placebo, in combination with a 26-week prednisolone taper regimen in adult subjects with GCA (EudraCT number: 2018-002610-12) (Venhoff, et al., 2021), inhibition of IL-17A by secukinumab has a potential therapeutic benefit for GCA patients.

The purpose of this study is to demonstrate the efficacy and safety of subcutaneously (s.c.) administered secukinumab 300 mg in combination with glucocorticoid taper regimen compared to placebo in combination with glucocorticoid taper regimen, in adult patients with new onset of giant cell arteritis (GCA) who are in clinical remission and who are eligible for treatment with glucocorticoid-monotherapy as per current clinical practice and treatment guidelines for the targeted participant population, thereby supporting health technology assessments (HTAs) of secukinumab in Germany.

   * Temporal artery biopsy revealing features of GCA AND/OR evidence of vasculitis in cranial or extracranial arteries by angiography or cross-sectional imaging study such as ultrasound, magnetic resonance angiography (MRA), computed tomography angiography (CTA), positron emission tomography - computed tomography (PET-CT)
5. Participants must be in clinical remission at BSL:

   - Definition of clinical remission: absence of signs and symptoms attributable to active GCA as determined by the investigator.

Exclusion Criteria:

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