ACHIEVING COMPREHENSIVE DISEASE CONTROL IN LONG-STANDING OR EARLY RHEUMATOID ARTHRITIS PATIENTS TREATED WITH ADALIMUMAB PLUS METHOTREXATE VERSUS METHOTREXATE ALONE

Background: Effective treatment of rheumatoid arthritis (RA) patients (pts) aims to suppress inflammation, preserve physical function, and prevent structural damage, which together represent the hallmarks of comprehensive disease control (CDC). Objectives: The present analysis evaluated CDC attainment following 1 year of treatment with adalimumab (ADA) + methotrexate (MTX) vs MTX alone in 3 different randomized, controlled trials (RCTs). Methods: Patient data originate from the DE019, OPTIMA, and PREMIER RCTs. DE019 enrolled pts with long-standing RA (mean =11 years) and an inadequate response (IR) to MTX; OPTIMA and PREMIER enrolled early RA (mean =0.4 and 0.7 years, respectively) and MTX-naïve pts. All studies included a comparison of ADA+MTX vs placebo (PBO)+MTX and were of at least 1 year duration. Changes to assigned treatment strategy were not allowed in DE019 or PREMIER but were made on the basis of achieving a stable low disease activity [LDA, DAS28(CRP) <3.2] target at weeks 22 and 26 in OPTIMA; PBO+MTX-IR could receive open-label (OL) ADA+MTX for an additional 52 weeks (Rescue ADA arm). CDC was defined for this analysis as the simultaneous achievement of LDA, normal function (HAQ-DI <0.5), and the absence of radiographic progression (ΔmTSS ≤0.5). Results: Approximately one-fifth (19%) of ADA+MTX-treated pts in DE019 achieved CDC at 1 year vs 5% of PBO+MTX-treated pts (P <.001, Table). The addition of OL ADA+MTX to PBO+MTX-IR in the Rescue ADA arm of OPTIMA permitted 29% (n/N=102/348) of early RA pts to achieve CDC following 1 year of treatment, a proportion that was comparable with the proportion of MTX-naïve early RA pts treated with ADA+MTX in PREMIER achieving CDC at 1 year (32%, n/N=87/268). Image/graph: Conclusions: CDC appears to be a realistic treatment goal in RA. Treatment with the combination of ADA+MTX earlier in the course of disease increased the likelihood of being able to achieve CDC. References: Smolen, et al.
