AB0405 Baseline Predictors of Remission Rates during Golimumab Treatment for Rheumatoid Arthritis in the GO-MORE Study
2014
Background In patients with rheumatoid arthritis (RA), current treatment strategies aim for clinical remission. Knowing which patients are likely to respond to biologic treatment is helpful when considering treatment options. Objectives To evaluate baseline characteristics that predict remission after 6 months of add-on golimumab (GLM) treatment in patients with active RA despite disease-modifying antirheumatic drug (DMARD) therapy. Methods GO-MORE was an open-label, multinational, prospective study in biologic-naive patients with active RA (28-joint disease activity score based on erythrocyte sedimentation rate [DAS28-ESR] ≥3.2) despite DMARD therapy. 1 Patients received 50-mg subcutaneous GLM once monthly for 6 months. In post hoc analyses, univariate logistic regression models were used to examine relationships between month-6 remission (DAS28-ESR 1.125 to P Results In 3280 efficacy-evaluable patients, mean disease duration was 7.6 years; mean DAS28–ESR was 5.97 (SD=1.095). Overall, 23.9% (784/3280) of patients attained remission after 6 months9 GLM treatment. 1 The final multivariate analyses of 6-month DAS28-ESR remission did not include baseline MTX dose, previously failed DMARDs, disease duration, PGA, and SJC28 because they were not significant in initial analyses. In the final model, lower likelihood of remission was associated with being female (vs male, odds ratio [OR]=.652, P P P P =.002]). Greater likelihood of remission was associated with lower baseline ESR (OR=.565) and TJC28 (OR=.943), P P =.0017). Smoking status was not associated with remission. Conclusions In this large, multinational, observational study of patients with RA treated with GLM, attainment of 6-month remission was associated with several baseline predictors, notably sex, ESR, TJC28, comorbidities, and HAQ. Factors not associated with remission included disease duration, SJC, number of failed DMARDs, and MTX dose. References Combe B et al. Ann Rheum Dis. doi:10.1136/annrheumdis-2013-203229.
