Background: Our objective was to evaluate the effect of background biological disease-modifying anti-rheumatic drugs (bDMARDs) and/or corticosteroids (CS) on response to nonsteroidal anti-inflammatory drugs (NSAIDs) in rheumatoid arthritis (RA) patients. Methods: The following efficacy endpoints were evaluated using time-weighted change from baseline in a 12-week, randomized controlled clinical trial with etoricoxib: Patient Global Assessment of Pain, Swollen Joint Count, Tender Joint Count, Health Assessment Questionnaire. The following three treatment groups were evaluated: placebo, pooled etoricoxib 10/30/60 mg, and etoricoxib 90 mg. Screening values, values post flare, as well as changes after treatment were analyzed. Results: Of the 1014 patients screened, 761 were randomized; 50% were on no background bDMARDs and/or CS therapy, 23% used bDMARDs, 34% used CS, and 8% used both bDMARDs and CS. It was demonstrated that RA patients on bDMARDs or CS had similar pain levels at screening as patients without this co-medication. They experienced flare upon NSAID withdrawal and demonstrated dose-dependent pain improvement with etoricoxib. Conclusion: These results support that RA patients receiving bDMARDs or CS may still require the use of concomitant analgesics to treat pain. Clinicians should continue to monitor and treat pain even after initiating a bDMARD and/or CS.
