Abstract

Background Assessment of structural damage progression, clinical efficacy and safety in patients with early-stage rheumatoid arthritis (RA) naïve to methotrexate (MTX) and with poor prognostic factors with certolizumab pegol (CZP) has not been performed so far.

Objectives To report the efficacy and safety of using CZP in combination with MTX compared to MTX alone, in early Japanese RA patients who were MTX-naïve with poor prognostic factors.

Methods Patients with early RA (<12 months from onset of persistent RA symptoms) fulfilling the 2010 ACR/EULAR Classification Criteria were enrolled in this multicenter, double-blind, randomized study (NCT01451203). Patients were included if they had poor prognostic factors: high-positive anti-CCP (>3xULN), and either positive rheumatoid factor or erosion on radiographs; were naïve to MTX, and had at least moderate disease activity (DAS28≥3.2). Patients were randomized 1:1 to either CZP+MTX or placebo (PBO)+MTX with oral MTX escalated to 16mg by Week (Wk) 8 unless safety issues and tolerability precluded further dose increase. The primary endpoint was inhibition of radiographic progression (change from baseline in modified total Sharp score [ΔmTSS]) at Wk52. Secondary endpoints were ΔmTSS at Wk24, and clinical remission rates by DAS28, ACR/EULAR (SDAI), and ACR/EULAR (Boolean) at Wks24 and 52.

Results The FAS population consisted of 316 patients with mean age 49.2±10.5yrs, symptoms duration 4.1±2.9 months, DAS28: 5.45±1.15 and mTSS: 5.55±12.43 at baseline, with the groups well-balanced. The average dose of concomitant MTX throughout the study was 11.61±2.8mg/wk. The CZP+MTX group (n=159) showed significantly greater inhibition of radiographic progression relative to the PBO+MTX group (n=157) at Wk52 (p<0.001) and at Wk24 (p=0.003) in the primary analyses of ANCOVA on the ranks. Similar results were obtained in the sensitivity analyses using ANCOVA at Wk52 (ΔmTSS=0.36 vs 1.58; p<0.001) and at Wk24 (ΔmTSS=0.26 vs 0.86; p=0.003). Clinical remission rates of the CZP+MTX group were significantly higher compared to those of the PBO+MTX group at Wk24 (DAS28: 52.8% vs 30.6% [p<0.001]; SDAI: 48.4% vs 29.3% [p<0.001]; Boolean: 36.5% vs 22.3% [p=0.007]) and at Wk52 (DAS28: 57.2% vs 36.9% [p<0.001]; SDAI: 57.9% vs 33.8% [p<0.001]; Boolean: 45.3% vs 28.0% [p=0.002]) (Figure). The combination therapy was well tolerated, with no new or unexpected safety signals observed.

Conclusions Combination of CZP with MTX was significantly more effective than PBO with MTX in inhibiting structural disease progression, as well as in achieving clinical remission in Japanese patients with early RA with poor prognostic factors.
