The GO-MORE study was an open-label, multinational, prospective study that investigated the efficacy and safety of adding golimumab to synthetic disease-modifying antirheumatic drugs (sDMARDs) in patients with active rheumatoid arthritis (RA).
The aim of this study was to assess the efficacy and safety of golimumab add-on therapy in the Polish subpopulation of the GO-MORE study.
Patients were administered 50 mg subcutaneous doses of golimumab once a month for 6 months, while continuing therapy with sDMARDs and/or glucocorticoids (GCS). The primary clinical endpoint was the proportion of patients with moderate or good European League Against Rheumatism (EULAR) response based on the 28-joint disease activity score (DAS28) erythrocyte sedimentation rate (ESR) after 6 months.
The Polish subpopulation (129 patients) was similar to the overall study population (3,280 patients) with regard to age, sex, mean baseline DAS28, inflammatory markers, average methotrexate dose, and GCS use; however, they had a longer disease duration (median: 6.04 vs 4.9 years) and more Polish patients (85.9% vs 78.7%) had high disease activity (DAS28-ESR ≥3.2). At 6 months, 84.5% of Polish patients showed good or moderate EULAR response, 26.4% had low disease activity and 17.1% were in clinical remission, compared with 82.9%, 37.4% and 23.9%, respectively, in the overall study population. Golimumab safety profile was consistent with previous studies and comparable to the overall study population.
The addition of golimumab to sDMARD therapy in Polish RA patients showed good or moderate EULAR DAS28-ESR response in 84.5% of patients, mirroring the overall study population.
