Predictors of Response to Tofacitinib Treatment in Rheumatoid Arthritis Patients

Study Overview
=================
Brief Summary
-----------------
This is a 24-month, prospective, non-interventional, multi-center study with primary aim to identify baseline characteristics of patients that predict response at 6 months of treatment. The study also aims to describe the treatment patterns of RA patients prescribed tofacitinib in a real-world setting and assess the effect of treatment on patient quality of life and physical function. Finally the study will assess the use of healthcare resources and costs in patients with RA treated with tofacitinib in Greece. The planned recruitment period is 12 months. The planned observation period of each patient is 12 months. In this time period up to 4 visits will be documented. The study will be reviewed and approved by the Central Regulatory Committee for NIS and IRB Board of each participating site
