Rheumatoid Arthritis
Conditions
Brief summary
This nationwide, multicenter, single arm, prospective, non-interventional study will evaluate the quantitative pattern of NSAID use and the impact of treatment with tocilizumab on NSAID use in a representative cohort of participant with moderate to severe active RA who have either responded inadequately to, or who were intolerant to previous therapy with one or more synthetic disease modifying anti-rheumatic drug (sDMARD), and for whom the physician has made the individual decision to initiate tocilizumab (subcutaneous \[SC\] or intravenous \[IV\]) as first biological disease modifying anti-rheumatic drug (DMARD) therapy according to the summary of product characteristics (SPC).
Interventions
DRUGTocilizumab
Tocilizumab (SC or IV) will be prescribed according to local clinical practice and the SPC.
DRUGNSAIDs
Participants may receive NSAIDs, as prescribed by the treating physician or by self medication. Study protocol does not enforce any particular NSAID.
