E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the efficacy of guselkumab compared to placebo, in combination with a 26-week glucocorticoid (GC) taper regimen, in adult participants with new-onset or relapsing giant cell arteritis (GCA) |
|
E.2.2 | Secondary objectives of the trial |
- To evaluate the efficacy of guselkumab compared to placebo, in combination with a 26-week GC taper regimen, in adult participants with new-onset or relapsing GCA as measured by alternative definitions of GC free remission, GC-sparing effects, and prevention of disease flares. - To evaluate the safety of guselkumab, in combination with a 26-week GC taper regimen, in adult participants with new-onset or relapsing GCA. - To evaluate the PK and immunogenicity of guselkumab, in combination with a 26-week GC taper regimen, in adult participants with new-onset or relapsing GCA.
