In the GiACTA trial,1 tocilizumab (TCZ) combined with prednisone (PDN) was significantly superior to PDN alone to obtain the remission in patients with giant cell arteritis (GCA) with and without concomitant large vessel vasculitis (LVV). To date, no data on the management of patients achieving the remission with TCZ monotherapy after a short course of combined treatment with CS are available.
To investigate the persistence of remission after TCZ interruption, we designed an open-label, prospective trial of 15 consecutive patients meeting the American College of Rheumatology 1990 criteria for GCA.2 Four patients had refractory GCA and 11 were new diagnoses (clinical and demographic data: see online supplementary table S1). All had concomitant thoracic LVV evidenced by 18-fluorodeoxyglucose (FDG)-positron emission tomography (PET)/CT. Total vascular score (TVS), maximal standardised uptake value (SUVmax) and target to background ratio …
