Abstract

Objectives

To assess the efficacy and safety of certolizumab pegol (CZP)+dose-optimised methotrexate (MTX) versus placebo (PBO)+dose-optimised MTX in inducing and sustaining clinical remission in DMARD-naïve patients with moderate-to-severe, active, progressive rheumatoid arthritis (RA), with poor prognostic factors over 52 weeks.

Methods

DMARD-naïve patients with ≤1 year of active RA were randomised (3:1) in a double-blind manner to CZP (400 mg Weeks 0, 2, 4, then 200 mg Q2W to Week 52)+MTX or PBO+MTX (the mean optimised-MTX dose=21 and 22 mg/week, respectively). Sustained remission (sREM) and sustained low disease activity (sLDA; DAS28(ESR)<2.6 and DAS28(ESR)≤3.2, respectively, at both Weeks 40 and 52) were the primary and secondary endpoints.

Results

Patients were randomised to CZP+MTX (n=660) and PBO+MTX (n=219). At Week 52, significantly more patients assigned to CZP+MTX compared with PBO+MTX achieved sREM (28.9% vs 15.0%, p<0.001) and sLDA (43.8% vs 28.6%, p<0.001). Inhibition of radiographic progression and improvements in physical functioning were significantly greater for CZP+MTX versus PBO+MTX (van der Heijde modified total Sharp score (mTSS) mean absolute change from baseline (CFB): 0.2 vs 1.8, p<0.001, rate of mTSS non-progressors: 70.3% vs 49.7%, p<0.001; least squares (LS) mean CFB in Health Assessment Questionnaire-Disability Index (HAQ-DI): −1.00 vs −0.82, p<0.001). Incidence of adverse events (AEs) and serious AEs was similar between treatment groups. Infection was the most frequent AE, with higher incidence for CZP+MTX (71.8/100 patient-years (PY)) versus PBO+MTX (52.7/100 PY); the rate of serious infection was similar between CZP+MTX (3.3/100 PY) and PBO+MTX (3.7/100 PY).

Conclusions

CZP+dose-optimised MTX treatment of DMARD-naïve early RA resulted in significantly more patients achieving sREM and sLDA, improved physical function and inhibited structural damage compared with PBO+dose-optimised MTX.

The PREMIER study: A multicenter, randomized, double-blind clinical trial of combination therapy with adalimumab plus methotrexate versus methotrexate alone or adalimumab alone in patients with early, aggressive rheumatoid arthritis who had not had previous methotrexate treatment.

Ferdinand C Breedveld, Michael Weisman, Arthur F Kavanaugh … (2006)

To compare the efficacy and safety of adalimumab plus methotrexate (MTX) versus MTX monotherapy or adalimumab monotherapy in patients with early, aggressive rheumatoid arthritis (RA) who had not previously received MTX treatment. This was a 2-year, multicenter, double-blind, active comparator-controlled study of 799 RA patients with active disease of < 3 years' duration who had never been treated with MTX. Treatments included adalimumab 40 mg subcutaneously every other week plus oral MTX, adalimumab 40 mg subcutaneously every other week, or weekly oral MTX. Co-primary end points at year 1 were American College of Rheumatology 50% improvement (ACR50) and mean change from baseline in the modified total Sharp score. Combination therapy was superior to both MTX and adalimumab monotherapy in all outcomes measured. At year 1, more patients receiving combination therapy exhibited an ACR50 response (62%) than did patients who received MTX or adalimumab monotherapy (46% and 41%, respectively; both P < 0.001). Similar superiority of combination therapy was seen in ACR20, ACR70, and ACR90 response rates at 1 and 2 years. There was significantly less radiographic progression (P < or = 0.002) among patients in the combination treatment arm at both year 1 and year 2 (1.3 and 1.9 Sharp units, respectively) than in patients in the MTX arm (5.7 and 10.4 Sharp units) or the adalimumab arm (3.0 and 5.5 Sharp units). After 2 years of treatment, 49% of patients receiving combination therapy exhibited disease remission (28-joint Disease Activity Score <2.6), and 49% exhibited a major clinical response (ACR70 response for at least 6 continuous months), rates approximately twice those found among patients receiving either monotherapy. The adverse event profiles were comparable in all 3 groups. In this population of patients with early, aggressive RA, combination therapy with adalimumab plus MTX was significantly superior to either MTX alone or adalimumab alone in improving signs and symptoms of disease, inhibiting radiographic progression, and effecting clinical remission.

Comparison of methotrexate monotherapy with a combination of methotrexate and etanercept in active, early, moderate to severe rheumatoid arthritis (COMET): a randomised, double-blind, parallel treatment trial.

Paul Emery, Ferdinand C Breedveld, Stephen D Hall … (2008)

Remission and radiographic non-progression are goals in the treatment of early rheumatoid arthritis. The aim of the combination of methotrexate and etanercept in active early rheumatoid arthritis (COMET) trial is to compare remission and radiographic non-progression in patients treated with methotrexate monotherapy or with methotrexate plus etanercept. 542 outpatients who were methotrexate-naive and had had early moderate-to-severe rheumatoid arthritis for 3-24 months were randomly assigned to receive either methotrexate alone titrated up from 7.5 mg a week to a maximum of 20 mg a week by week 8 or methotrexate (same titration) plus etanercept 50 mg a week. Coprimary endpoints at 52 weeks were remission measured with the disease activity score in 28 joints (DAS28) and radiographic non-progression measured with modified total Sharp score. Treatment was allocated with a computerised randomisation and enrolment system, which masked both participants and carers. Analysis was done by modified intention to treat with last observation carried forward for missing data. This study is registered with ClinicalTrials.gov, number NCT00195494). 274 participants were randomly assigned to receive combined treatment and 268 methotrexate alone. 132 of 265 (50%, 95% CI 44-56%) patients who took combined treatment and were available for assessment achieved clinical remission compared with 73 of 263 (28%, 23-33%) taking methotrexate alone (effect difference 22.05%, 95%CI 13.96-30.15%, p 5.1). 196 of 246 (80%, 75-85%) and 135 of 230 (59%, 53-65%), respectively, achieved radiographic non-progression (20.98%, 12.97-29.09%, p<0.0001). Serious adverse events were similar between groups. Both clinical remission and radiographic non-progression are achievable goals in patients with early severe rheumatoid arthritis within 1 year of combined treatment with etanercept plus methotrexate.

Certolizumab pegol plus methotrexate is significantly more effective than placebo plus methotrexate in active rheumatoid arthritis: findings of a fifty-two-week, phase III, multicenter, randomized, double-blind, placebo-controlled, parallel-group study.

Edward Clark Keystone, Désirée Heijde, David Mason … (2008)

To evaluate the efficacy and safety of 2 dosage regimens of lyophilized certolizumab pegol (a novel PEGylated anti-tumor necrosis factor agent) as adjunctive therapy to methotrexate (MTX) in patients with active rheumatoid arthritis (RA) with an inadequate response to MTX therapy alone. In this 52-week, phase III, multicenter, randomized, double-blind, placebo-controlled, parallel-group trial, 982 patients were randomized 2:2:1 to receive treatment with subcutaneous certolizumab pegol at an initial dosage of 400 mg given at weeks 0, 2, and 4, with a subsequent dosage of 200 mg or 400 mg given every 2 weeks, plus MTX, or placebo plus MTX. Co-primary end points were the response rate at week 24 according to the American College of Rheumatology 20% criteria for improvement (ACR20) and the mean change from baseline in the modified total Sharp score at week 52. At week 24, ACR20 response rates using nonresponder imputation for the certolizumab pegol 200-mg and 400-mg groups were 58.8% and 60.8%, respectively, as compared with 13.6% for the placebo group. Differences in ACR20 response rates versus placebo were significant at week 1 and were sustained to week 52 (P < 0.001). At week 52, mean radiographic progression from baseline was reduced in patients treated with certolizumab pegol 200 mg (0.4 Sharp units) or 400 mg (0.2 Sharp units) as compared with that in placebo-treated patients (2.8 Sharp units) (P < 0.001 by rank analysis). Improvements in all ACR core set of disease activity measures, including physical function, were observed by week 1 with both certolizumab pegol dosage regimens. Most adverse events were mild or moderate. Treatment with certolizumab pegol 200 or 400 mg plus MTX resulted in a rapid and sustained reduction in RA signs and symptoms, inhibited the progression of structural joint damage, and improved physical function as compared with placebo plus MTX treatment in RA patients with an incomplete response to MTX.
