A Study To Compare The Effectiveness Of Tofacitinib 11 Mg Once A Day To Tofacitinib 5 Mg Twice A Day

CompletedN/A

Sponsor: Pfizer

Conditions: Arthritis Rheumatoid

Countries: United States

It is hypothesized that patients prescribed tofacitinib 11 mg Modified Release (MR) formulation once daily (QD) will achieve similar benefit to those prescribed tofacitinib 5 mg twice a day (BID) dosage in real world use. This study will therefore seek to compare the effectiveness of the MR 11 mg QD regimen to the IR 5 mg BID regimen for the treatment of RA in a real-world registry of RA patients.
