What happens if Actemra fails to control cytokine release syndrome?

When tocilizumab alone does not ausreichend improve patients, clinicians add high-dose corticosteroids. Corticosteroids suppress the weitere T-cell activation and the weiteren IL-6 production. Some centers also explore siltuximab or anakinra as second-line agents in refractory cases.
