Part 1 of this trial will assess the safety and effectiveness of subcutaneous (SC) golimumab administered by autoinjector once monthly, when combined with different disease-modifying antirheumatic drug (DMARD) regimens used in daily rheumatology practice. Subsequently, Part 2 will study if a strategy of intravenous (IV) golimumab to induce remission followed by SC golimumab to retain remission is superior to continuing a SC regimen.
