The usual percentage of patients receiving 0.1 mg/Kg/d or less of prednisone after 6 months of treatment is approximately 40%. We believe that adding tocilizumab to the corticotherapy in this protocol could increase the percentage from 40 to 70%.

From an immunological point of view, we believe we will see not only a fall in the Th17 response (as with corticoids alone), but also a rise in Treg lymphocytes.

Condition Intervention Phase
Horton's Disease Drug: corticoids+ tocilizumab 8mg/Kg/month Phase 2
