Abstract

Abstract : Background: Feasibility of discontinuation of biologic agents in patients with rheumatoid arthritis (RA) who have reached stable remission has been investigated. Although evidence has been accumulating regarding tumour necrosis factor inhibitors, the possibility of tocilizumab-free strategy is still unclear. Objectives: To evaluate the sustained remission and low disease activity after discontinuation of tocilizumab in patients with RA who were treated with tocilizumab alone or in combination with methotrexate. Methods: The SURPRISE study was a 2 year randomised, controlled study. Patients with active RA despite methotrexate were randomised to tocilizumab added to methotrexate (ADD-ON) or switch to tocilizumab alone (SWITCH). At week 52, tocilizumab was discontinued in patients who achieved remission based on disease activity score for 28 joints (DAS28-ESR<2.6). The endpoints of the second year included tocilizumab-free sustained remission rates at week 104, sustained low disease activity rates, radiological outcomes assessed with the modified total Sharp score (mTSS), and safety. The efficacy of re-instituted tocilizumab/methotrexate was also assessed. Results: 105 patients who achieved remission at 52 week discontinued tocilizumab; 51 in the ADD-ON continued methotrexate and 54 in the SWITCH were observed without medication. Whereas sustained DAS28 remission rates at week 104 were 24% for the ADD-ON and 14% for the SWITCH (p=0.29), sustained low disease activity rate was significantly higher in the ADD-ON than in the SWITCH (55% vs 27%, p=0.005, figure 1). Radiographical progression was comparable in the 2 groups (mTSS; 0.37 vs 0.64, p=0.36). Re-start of tocilizumab induced remission in all patients except two irrespective of concurrent methotrexate after 36 weeks while re-start of methotrexate was effective only in a half of patients. Conclusions: Sustained low disease activity after tocilizumab discontinuation could be maintained with continued methotrexate in more than half of patients. Re-treatment with tocilizumab led remission in more than 90% patients. Disclosure of Interest: Y.
