Subcutaneous Golimumab (GLM) Plus DMARDs for Rheumatoid Arthritis, Followed by Intravenous/Subcutaneous GLM Strategy (P06129 AM2)

Study Overview
=================
Brief Summary
-----------------
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.

Detailed Description
-----------------
Participants who had a good or moderate European League Against Rheumatism (EULAR) response but not achieve remission at the end of Part 1 were invited to participate in Part 2 and were randomized to either intravenous golimumab (IV GLM) + subcutaneous golimumab (SC GLM) or SC GLM alone.
