In this study, we compare the health-related quality of life (HRQoL) of patients with moderate-to-severe rheumatoid arthritis (RA), psoriatic arthritis (PsA), and ankylosing spondylitis (AS), and study the effect of treatment with infliximab on the HRQoL of patients with these diseases. Short Form Health Survey-36 (SF-36) data from the placebo-controlled phases of 4 studies of infliximab in patients with inflammatory rheumatic diseases (n = 1990) were evaluated. Data came from the Anti-TNF Trial in Rheumatoid Arthritis with Concomitant Therapy (ATTRACT) (n = 428), the Safety Trial for Rheumatoid Arthritis with REMICADE Therapy (START) (n = 1083), the Ankylosing Spondylitis Study for the Evaluation of Recombinant Infliximab Therapy (ASSERT) (n = 279), and the Infliximab Multinational Psoriatic Arthritis Clinical Trial II (IMPACT II) (n = 200). SF-36 assessments were made at weeks 0, 10, 30, and 54 in ATTRACT, weeks 0, 6, and 22 in START, weeks 0, 12, and 24 in ASSERT, and weeks 0 and 14 in IMPACT II. All patient populations had significantly impaired physical aspects of HRQoL at baseline relative to the general population of the United States, and the magnitude of impairment was similar across the diseases. Mean baseline physical component summary scores were 29 in the RA cohort, 32 in the PsA cohort, and 29 in the AS cohort. In all 3 diseases, patients who received infliximab showed significant improvement in physical component summary scores compared with those who received placebo. The magnitude of the difference of improvement (effect size, 95%CI) between infliximab and placebo groups was similar in the AS (10.1, 9.2–11.0), PsA (8.6, 7.8–9.4), and RA (10.1, 9.2–11.0) cohorts. Patients with RA and those with PsA treated with infliximab also showed greater improvement in the mental component summary score than those in the placebo group with an effect size of 4.6 (4.2–5.1) in RA and 2.7 (2.4–3.1) in PsA. Patients in large randomized controlled studies of infliximab in RA, PsA, and AS had similar impairment in physical aspects of HRQoL at baseline and showed significantly greater improvement in HRQoL after treatment with infliximab.

OBJECTIVE To evaluate the effect of antitumor necrosis factor-alpha monoclonal antibody infliximab treatment on anemia in patients with rheumatoid arthritis (RA). METHODS Data from patients with RA who received infliximab or placebo in the multicenter, placebo-controlled, double-blind, randomized ATTRACT, ASPIRE, and START studies were included in this post-hoc, pooled analysis. Infliximab (3 to 10 mg/kg) was administered every 4 or 8 weeks, and all patients received stable doses of methotrexate (MTX). We determined the percentage of anemic patients (baseline hemoglobin level <12 g/dL) who had an increase from baseline in hemoglobin level greater than or equal to 1 or 2 g/dL or achieved normal hemoglobin level at week 22. The association of improvement in anemia with improvement in clinical parameters was also evaluated. RESULTS Among patients with anemia at baseline, infliximab plus MTX treatment produced a significantly greater mean (standard deviation) increase in hemoglobin level from baseline to week 22 (0.74 [1.12], P < 0.0001) than placebo plus MTX (0.30 [0.92]). Significantly (P < 0.001) greater proportions of anemic patients treated with infliximab plus MTX had either at least a 1 g/dL (40%) or at least a 2 g/dL (12%) increase in hemoglobin level from baseline to week 22 or achieved normal hemoglobin level (43%) when compared with placebo plus MTX (19, 5, and 28%, respectively). Greater improvement in hemoglobin level among infliximab plus MTX-treated patients was consistently observed across subgroups and in patients without clinical response (American College of Rheumatology 20% response criteria) at week 22. Multiple regression analysis indicated that the effect of infliximab plus MTX on anemia was independent of improvement in disease activity. CONCLUSION Treatment with infliximab plus MTX significantly improved hemoglobin level among anemic RA patients when compared with treatment with placebo plus MTX, even after adjusting for improvement in disease activity.

OBJECTIVE To compare employability between patients with early and long-standing rheumatoid arthritis (RA) and examine the relationships between improvement in employability and disease stage after adjustment for demographic characteristics, disease activity, physical functioning, and response to therapy. METHODS We evaluated the employability data from 2 double-blind, randomized, placebo-controlled studies of infliximab plus methotrexate (MTX) in patients with RA. Patients were incomplete responders to MTX in 1 study and had never taken MTX in the other study. Patients age <65 years were categorized as having early RA (< or =3 years disease duration) or long-standing RA (>3 years disease duration). Physical functioning was assessed using the Health Assessment Questionnaire (HAQ) and clinical response was determined based on the American College of Rheumatology 20% improvement criteria (ACR20). RESULTS Patients with early RA were more likely to be employable at baseline than those with long-standing RA, even after adjusting for baseline HAQ scores. Among patients who were not employable at baseline but achieved an ACR20 response after 1 year of treatment, after adjusting for baseline HAQ score, the patients with early RA who had never taken MTX were 3 times more likely to become employable compared with those with long-standing RA who had an incomplete response to MTX at baseline. CONCLUSION In 2 clinical trials, patients with early RA were more likely to show improved employment outcomes after treatment than those with long-standing RA, suggesting intervention as early as possible in the disease course maximizes an individual patients employment potential.

Objective. To evaluate the effect of golimumab on physical function, general health, and fatigue in patients with active rheumatoid arthritis (RA) despite methotrexate (MTX) therapy. Methods. In the multicenter, randomized, placebo-controlled GO-FORWARD study, 444 adults with active RA despite MTX received subcutaneous placebo + MTX (crossover to golimumab 50 mg at Week 24), golimumab 100 mg + placebo, golimumab 50 mg + MTX, or golimumab 100 mg + MTX every 4 weeks. Physical function and general health were assessed using the Health Assessment Questionnaire-Disability Index (HAQ-DI) and Physical and Mental Component Summary (PCS, MCS) scores of the Medical Outcomes Study Short Form-36 questionnaire (SF-36), respectively, through Week 52. Fatigue was measured through Week 24 using the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue) questionnaire. Results. Mean improvements from baseline in HAQ-DI, SF-36 PCS, and FACIT-Fatigue scores (Weeks 14 and 24) were significantly greater for golimumab 50 mg + MTX and 100 mg + MTX versus placebo + MTX. Significantly greater proportions of patients treated with golimumab + MTX achieved clinically meaningful improvements from baseline to Weeks 14 and 24 in HAQ-DI, PCS, and FACIT-Fatigue scores. Mean improvements in SF-36 PCS (Week 14), MCS (Week 24), and FACIT-Fatigue (Weeks 14 and 24) scores were significantly greater for golimumab 100 mg + placebo versus placebo + MTX. Mean improvements from baseline in HAQ-DI, SF-36 PCS, and MCS scores through Week 24 were sustained through Week 52. Conclusion. Patients with active RA despite MTX had significant improvement in physical function, general health, and fatigue following golimumab + MTX therapy; improvements in physical function and general health were maintained through Week 52.

OBJECTIVE Anemia is a common complication in patients with inflammatory diseases such as ankylosing spondylitis (AS). This post hoc analysis of a large, randomized, placebo-controlled trial examined the effect of infliximab on hemoglobin levels, physical function, and fatigue in patients with AS. METHODS Patients received infliximab 5 mg/kg (n = 188) or placebo (n = 68) at weeks 0, 2, 6, 12, and 18. Hemoglobin, interleukin-6 (IL-6), and C-reactive protein (CRP) levels, fatigue (visual analog scale [VAS]), physical function (Bath Ankylosing Spondylitis Functional Index [BASFI]), and disease activity were evaluated at baseline and week 24. Anemia was defined as a hemoglobin level <12 gm/dl for women and <13 gm/dl for men. RESULTS At baseline, 11 placebo group patients (16.2%) and 37 infliximab group patients (19.7%) had anemia. Of these, more infliximab-treated patients achieved normal hemoglobin levels at week 24 compared with patients receiving placebo (70.3% versus 27.3%; P = 0.0155). Infliximab-treated patients had significant improvements in mean hemoglobin concentration (0.7 gm/dl versus -0.3 gm/dl), BASFI score (-2.1 versus -0.2), and fatigue VAS score (-2.4 versus -0.4) compared with placebo patients (P < 0.001). Multiple regression analyses showed that improvements in hemoglobin level were significantly and independently associated with improvements in physical function and fatigue. Infliximab-treated patients with elevated CRP or IL-6 levels at baseline were more likely than those with low levels to have improvement in hemoglobin levels. CONCLUSION Infliximab treatment significantly decreased the proportion of AS patients with anemia and improved hemoglobin levels compared with placebo. Improvement in hemoglobin level was independently associated with improvements in physical function and fatigue.

Objective. To evaluate the effects of golimumab therapy on achieving inactive disease or major improvement, as assessed by the Ankylosing Spondylitis Disease Activity Score (ASDAS), and improvements in health-related quality of life (HRQOL) and productivity through 2 years in patients with AS. Methods. In the phase III GO-RAISE trial, 356 patients were randomized to placebo with crossover to golimumab 50 mg at Week 24 (n = 78), golimumab 50 mg (n = 138), or golimumab 100 mg (n = 140) at baseline and every 4 weeks. The proportions of patients with ASDAS major improvement (improvement ≥ 2.0) or inactive disease (score < 1.3) were determined. HRQOL was assessed using the 36-item Medical Outcomes Study Short Form-36 physical/mental component summary (SF-36 PCS/MCS) scores (normal score ≥ 50). The effect of disease on productivity was assessed by visual analog scale (0–10). Regression analyses on the association of disease activity and HRQOL were performed. The final assessment was at Week 104. Results. Significantly greater proportions of golimumab-treated patients achieved ASDAS major improvement or inactive disease at weeks 14 and 24 versus placebo. Through Week 104, patients who achieved ASDAS inactive disease or major improvement had significantly greater improvements in SF-36 PCS and MCS scores and productivity than did patients not meeting these targets. Among all patients, achieving ASDAS inactive disease at weeks 52 and 104 was associated with normalized SF-36 PCS/MCS scores and significant improvements in work productivity. Conclusion. Greater proportions of golimumab-treated patients achieved ASDAS major improvement or inactive disease and improved HRQOL versus placebo. Achieving an inactive disease state by ASDAS criteria (< 1.3) was associated with normalized HRQOL through 2 years.

Objective. To evaluate the effects of intravenous (IV) golimumab 2 mg/kg + methotrexate (MTX) on patient-reported measures of health-related quality of life (HRQOL) in patients with active rheumatoid arthritis (RA) despite prior MTX therapy. Methods. In this randomized, multicenter, double-blind, placebo-controlled, phase III trial, adults with RA were randomly assigned to receive IV placebo (n = 197) or golimumab 2 mg/kg (n = 395) infusions at Week 0, Week 4, and every 8 weeks thereafter. All patients continued stable oral MTX (15–25 mg/wk). HRQOL assessments included Health Assessment Questionnaire-Disability Index (HAQ-DI; physical function), Medical Outcomes Study Short Form-36 questionnaire physical/mental component summary (SF-36 PCS/MCS) scores, EQ-5D assessment of current health state, Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue) questionnaire, and disease effect on productivity [10-cm visual analog scale (VAS)]. Results. Mean HAQ-DI improvements from baseline were significantly greater with golimumab + MTX than placebo + MTX at Week 14 and Week 24 (p < 0.001). Significantly greater improvements in all 8 individual SF-36 subscores and both the SF-36 PCS and MCS scores (p < 0.001) also accompanied golimumab + MTX therapy. Improved EQ-5D and EQ-5D VAS (p < 0.001) and FACIT-Fatigue (p < 0.001) scores were also observed for golimumab + MTX-treated patients at Week 12, Week 16, and Week 24, and greater proportions of golimumab + MTX-treated patients had clinically meaningful improvements in these measures. Greater reductions in disease effect on productivity were observed with golimumab + MTX versus placebo + MTX at Week 24 (p < 0.001). Improvements in physical function, HRQOL, fatigue, and productivity significantly correlated with disease activity improvement. Conclusion. In active RA, IV golimumab + MTX significantly improved physical function, HRQOL, fatigue, and productivity using multiple measurement tools; all correlated with improvements in disease activity (NCT00973479, EudraCT 2008-006064-11).

Objective. To evaluate the safety and efficacy of golimumab (GOL), a human antitumor necrosis factor antibody, in patients with active rheumatoid arthritis (RA) despite methotrexate (MTX) therapy through 5 years in the GO-FORWARD trial. Methods. Patients with active RA despite MTX therapy were randomly assigned to receive placebo + MTX (Group 1), GOL 100 mg + placebo (Group 2), GOL 50 mg + MTX (Group 3), or GOL 100 mg + MTX (Group 4). Patients in groups 1, 2, and 3 with inadequate response could enter early escape at Week 16 to GOL 50 mg + MTX or GOL 100 mg + MTX, and all remaining Group 1 patients crossed over to GOL 50 mg + MTX at Week 24. The blind was maintained through the 52-week database lock, after which treatment adjustments were permitted. Adverse events (AE) were monitored through Week 268. Efficacy was evaluated using the American College of Rheumatology (ACR) 20/50/70 responses and a 28-joint Disease Activity Score using C-reactive protein (DAS28-CRP). Response rates at Week 256 were analyzed by an intent-to-treat analysis. Results. A total of 444 patients were randomized, and 313 received GOL through Week 252; 301 patients completed the safety followup through Week 268. Infections were the most common type of AE; 172 patients (39.6%) had ≥ 1 serious AE. No unexpected safety signals were observed. At Week 256, ACR20/50/70 responses were achieved by 63.1%, 40.8%, and 24.1%, respectively, of all randomized patients. About 78% of all patients achieved a good or moderate DAS28-CRP response. Conclusion. Improvements in the signs and symptoms of RA were maintained through 5 years. AE through 5 years were consistent with earlier reports of the GO-FORWARD trial; no apparent increased risk was observed over time.
