NO DIFFERENCES IN PATIENT-REPORTED OUTCOMES BY METHOTREXATE DOSE AMONG EARLY RHEUMATOID ARTHRITIS PATIENTS TREATED CONCOMITANTLY WITH ADALIMUMAB: RESULTS FROM THE CONCERTO TRIAL
Annals of the Rheumatic Diseases(2013)
Abstract
Background Methotrexate (MTX) in combination with the tumor necrosis factor inhibitor adalimumab (ADA) is an effective therapy for treating rheumatoid arthritis (RA), but the minimum dose of MTX in combination with ADA that can achieve an acceptable clinical response is not known. Objectives To evaluate different MTX doses in combination with ADA in achieving clinically meaningful improvement in patient-reported outcomes (PROs) in patients (pts) with early RA. Methods CONCERTO was a 26-week (wk), phase 3, double-blind, parallel-arm study in MTX-naive pts with active RA Results Of the 395 pts included in the intent-to-treat population, 358 (91%) completed 26 wks of treatment; 15, 7, 6, and 9% of pts receiving 2.5, 5, 10, or 20 mg MTX, respectively, discontinued treatment prior to completion. Clinically and statistically significant improvements from wk 0 in most PROs occurred in all 4 dose groups by 8 wks, were maintained through 26 wks, and were similar regardless of MTX dose with no statistically significant difference between the dose groups with respect to the HAQ-DI, PCS, and MCS. Image/graph Conclusions Pts treated with ADA in combination with MTX 2.5, 5, 10 or 20 mg per wk experience similar improvements in PROs by wk 8 that are maintained through 26 wks. The differences associated with MTX dose are not statistically significant and, in general, not clinically meaningful. Acknowledgements AbbVie Inc. funded the study (NCT01185301).
