Abstract
BACKGROUND The type of failure may predict response to a second biologic. We evaluated the response to a second tumor necrosis factor inhibitor (TNFi) or non-TNFi in patients failing their initial TNFi, either primarily or secondarily. METHODS Patients with rheumatoid arthritis who were biologic-naive and had a Clinical Disease Activity Index (CDAI) >10, who started their first TNFi for ≥3 months and then switched to a second biologic, were included in the study. Secondary failure was defined as 2 consecutive low-CDAI visits and then switching to a second biologic while they had moderate/severe CDAI. Primary failure was defined if it did not meet the definition of secondary failure, or if they had at least 1 moderate/severe CDAI after 3 months on treatment. We used multivariable logistic regression comparing primary versus secondary failure for achievement of CDAI ≤10 (primary outcome) and minimal clinically important differences (secondary outcome) at 6 months after switch. RESULTS Of the 462 patients included, 64.3% and 35.7% stopped the first TNFi because of a primary and secondary failure, respectively. Patients with primary failure had a more severe disease (CDAI mean, 26.39 vs. 21.61; p < 0.001). The likelihood of achieving CDAI ≤10 (odds ratio, 4.367; 95% confidence interval, 2.428-7.856) and minimal clinically important difference (odds ratio, 2.851; 95% confidence interval, 1.619-5.020) was significantly higher for secondary than primary failure regardless of choice of a second agent. CONCLUSION Patients with rheumatoid arthritis with secondary failure to a first TNFi responded better to a second biologic agent, regardless of the choice of biologic.

Long-Term Durability of Certolizumab Pegol in Patients with Rheumatoid Arthritis Over 5 Years: An Analysis of Pooled Clinical Trial Data. Rheumatol Ther 2023; 10:693-706. [PMID: 36848009 PMCID: PMC10140240 DOI: 10.1007/s40744-023-00541-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2022] [Accepted: 02/09/2023] [Indexed: 03/01/2023] Open
Abstract
INTRODUCTION There is a paucity of data on how patient characteristics may affect the long-term durability of certolizumab pegol (CZP) in patients with rheumatoid arthritis (RA). This study therefore aimed to investigate CZP durability and reasons for discontinuation over 5 years between different subgroups of patients with RA. METHODS Data were pooled from 27 clinical trials in RA patients. Durability was defined as the percentage of patients randomized to CZP at baseline who were still on CZP treatment at a given timepoint. Post hoc analyses of clinical trial data on CZP durability and reasons for discontinuation among different patient subgroups were conducted using Kaplan-Meier curves and Cox proportional hazards modeling. Patient subgroups included: age (18- < 45/45- < 65/ ≥ 65 years), gender (male/female), prior tumor necrosis factor inhibitor (TNFi) use (yes/no), and disease duration (< 1/1- < 5/5- < 10/ ≥ 10 years). RESULTS Among 6927 patients, the durability of CZP was 39.7% at 5 years. Patients aged ≥ 65 years had a 33% greater risk of CZP discontinuation than patients 18- < 45 years (hazard ratio [95% confidence interval]: 1.33 [1.19-1.49]) and patients with prior TNFi use had a 24% greater risk of discontinuing CZP than patients without (1.24 [1.12-1.37]). Conversely, greater durability was observed among patients who had a baseline disease duration of ≥ 1 year. Durability did not differ in the gender subgroup. Of the 6927 patients, the most common reason for discontinuation was inadequate levels of efficacy (13.5%); followed by adverse events (11.9%); consent withdrawn (6.7%); lost to follow-up (1.8%); protocol violation (1.7%); other reasons (9.3%). CONCLUSIONS CZP durability was comparable with durability data on other bDMARDs in RA patients. Patient characteristics that were associated with greater durability included younger age, TNFi-naïvety, and disease duration ≥ 1 year. Findings may be helpful in informing clinicians on a patient's likelihood of discontinuing CZP, based on their baseline characteristics.

Abstract
Since we have gained an understanding of the immunological pathophysiology of rheumatic diseases such as rheumatoid arthritis and systemic lupus erythematosus, treatment based on biological drugs has become a fundamental axis. These therapies are oriented towards the regulation of cytokines such as tumour necrosis factor-alpha (TNF-α), interleukin (IL)-6, IL-1, and the modulation of cell-mediated immunity (B cells and T cells) by anti CD20 or anti CTAL-4 agents, and can increase the risk of associated infections or adverse events (AE). In this context, the entry of biotherapeutics represented a challenge for pharmacovigilance, risk management and approval by the main global regulatory agencies regarding biosimilars, where efficacy and safety are based on comparability exercises without being an exact copy in terms of molecular structure. The objective of this review is divided into three fundamental aspects: (i) to illustrate the evolution and focus of pharmacovigilance at the biopharmaceutical level, (ii) to describe the different approved recommendations of biopharmaceuticals (biological and biosimilars) and their use in rheumatic diseases (RDs) such as rheumatoid arthritis (RA), juvenile idiopathic arthritis (JIA), psoriatic arthritis (PsA), ankylosing spondylitis (AS), systemic lupus erythematosus (SLE) and other less frequent RD like cryopyrin-associated autoinflammatory syndromes (CAPS), and (iii) to identify the main AE reported in the post-marketing phase of RD biopharmaceuticals.

Abstract
Background Our study aimed to compare efficacy and safety of Hetero's adalimumab (Mabura®, Hetero Biopharma Limited) versus reference adalimumab (Humira®, Abbvie Inc.) in Indian patients with active rheumatoid arthritis (RA) concomitant on methotrexate (MTX) therapy. Methods Patients (n = 168) were randomized (2:1) to receive either test or reference product for 24 weeks with concomitant MTX. Proportion of patients achieving American College of Rheumatology 20 (ACR20) criteria at week 12 was the primary endpoint. Changes in Disease Activity Score of 28 joints-C-reactive protein (DAS28-CRP), Health Assessment Questionnaire-Disability Index (HAQ-DI), and patients achieving ACR20 at week 24, ACR50/70 at weeks 12 and 24 were secondary endpoints. Results Patients achieving ACR20 responses with test (96.43%) were similar to reference (96.43%) in intention-to-treat (ITT) analysis at week 12. Proportional difference (PD) between groups (PD [95% CI] 0.0 [- 6.0, 6.0], p = 1.000) for ACR20 at week 12 for ITT analysis showed lower limit of the two-sided 95% CI was above the pre-specified noninferiority margin of - 15%. Similar trend in PP analysis (PD [95% CI] 0.0 [- 0.03, 0.07], p = 1.000), confirmed therapeutic equivalence. No significant difference was noted between arms for patients attaining ACR20 at week 24 and ACR50/70 at weeks 12 and 24 (all p > 0.05). DAS28-CRP and HAQ-DI were similar between groups. Total of 54 patients reported 88 AEs during the study. Out of these, 60 AEs were reported in 34 patients with Hetero-Adalimumab and 28 AEs were reported in 20 patients with Reference-Adalimumab. Total two patients, one in each group reported two serious adverse events (Sinusitis and Viral infection) during the study and resolved completely. No deaths and no life threatening AEs were reported. Conclusion Results demonstrated Hetero's adalimumab is as effective and well tolerated as reference adalimumab in patients with active RA concomitantly on MTX therapy.

Abstract
INTRODUCTION The safety profile of adalimumab was previously reported in 23,458 patients across multiple indications. Here we report the long-term safety of adalimumab in adults with plaque psoriasis (Ps), hidradenitis suppurativa (HS), rheumatoid arthritis (RA), ankylosing spondylitis, psoriatic arthritis, non-radiographic axial spondyloarthritis, peripheral spondyloarthritis, Crohn's disease (CD), ulcerative colitis (UC), and non-infectious uveitis (UV). METHODS Safety data from 77 clinical trials were pooled. Safety assessments included adverse events (AEs) and serious AEs (SAEs) that occurred after the first study dose and within 70 days (5 half-lives) after the last study dose. RESULTS A total of 29,967 patients were included, representing 56,916 patient-years (PY) of exposure. The most frequently reported SAE of interest was infection (3.7/100 PY) with highest incidences in CD, RA, UV, and UC (3.5/100 PY-6.9/100 PY); serious infections in Ps (1.8/100 PY) and HS (2.8/100 PY) were lower. The observed number of deaths was below what would be expected in an age- and sex-adjusted population for most adalimumab-treated patients (including Ps). Lack of real-life data and limited long-term data (> 5 years) for most patients are limitations of this analysis. CONCLUSION The safety profile of adalimumab was consistent with previous findings and no new safety signals were observed.

Abstract
OBJECTIVE To evaluate the safety of adalimumab in pediatric patients who participated in clinical trials of juvenile idiopathic arthritis (polyarticular juvenile idiopathic arthritis and pediatric enthesitis-related arthritis), psoriasis, and Crohn's disease. STUDY DESIGN This analysis included data from 7 global, randomized, and open-label AbbVie-sponsored clinical trials of adalimumab and their open-label extensions conducted between September 2002 and December 31, 2015 (cutoff date for ongoing studies). Patients who received ≥1 dose of adalimumab subcutaneously were included. Adverse events that occurred after the first dose of adalimumab and up to 70 days (5 half-lives) after the last dose were reported and events per 100 patient-years were calculated. RESULTS The analysis included 577 pediatric patients, representing 1440.7 patient-years of adalimumab exposure. Across indications, the most commonly reported adverse events (events/100 patient-years) were upper respiratory tract infections (24.3), nasopharyngitis (17.3), and headache (19.9). Serious infections (4.0 events/100 patient-years) were the most frequent serious adverse events across indications; the most commonly reported was pneumonia (0.6 events/100 patient-years). Serious infection rates were 2.7, 0.8, and 6.6 events/100 patient-years in patients with juvenile idiopathic arthritis, psoriasis, and Crohn's disease, respectively. No events of malignancies were reported. One death (accidental fall) occurred in a patient with psoriasis. CONCLUSIONS The safety profile of adalimumab in pediatric patients with polyarticular juvenile idiopathic arthritis, enthesitis-related arthritis, psoriasis, and Crohn's disease was generally similar across indications; no new safety signals were identified in the treatment of pediatric patients with adalimumab.

Abstract
Objectives Describe efficacy and safety of 3 years of adalimumab treatment in patients with peripheral spondyloarthritis (pSpA) and identify predictors of remission. Methods Patients with pSpA were randomised to adalimumab 40 mg every other week or placebo for 12 weeks; a 144-week open-label extension followed (NCT01064856). Remission was assessed by the Peripheral SpA Response Criteria (PSpARC) and Ankylosing Spondylitis Disease Activity Score inactive disease (ASDAS ID). Logistic regression analyses were performed to determine predictors of remission at 1 and 3 years and sustained remission (≥24 consecutive weeks). Results In 165 patients, ASDAS ID was achieved by 47% at 1 year and 39% at 3 years; 36% and 33% achieved PSpARC remission, respectively. Sustained ASDAS ID and PSpARC remission were achieved by 52% (86/165) and 42% (70/165) of patients, respectively. Achieving ASDAS ID at week 12 significantly predicted 1 year (OR, 8.64 (95% CI 2.97 to 25.14)), 3 year (OR, 36.12 (95% CI 2.29 to 569.08)) and sustained ASDAS ID (OR, 8.01 (95% CI 2.47 to 25.97)); achieving PSpARC remission at week 12 consistently predicted 1 year (OR, 6.47 (95% CI 1.91 to 21.95)), 3 years (OR, 15.66 (95% CI 4.19 to 58.56)) and sustained PSpARC remission (OR, 20.27 (95% CI 5.37 to 76.46)). No baseline variables consistently predicted 1-year or 3-year remission or sustained remission. The safety profile of adalimumab was consistent with observations in other SpA disease indications. Conclusions In patients with pSpA, early response to adalimumab, but not baseline demographics or disease characteristics, was a better predictor of long-term remission.

Abstract
BACKGROUND This study aimed to compare efficacy and safety of test-adalimumab (CinnoRA®, CinnaGen, Iran) to the innovator product (Humira®, AbbVie, USA) in adult patients with active rheumatoid arthritis (RA). METHODS In this randomized, double-blind, active-controlled, non-inferiority trial, a total of 136 patients with active RA were randomized to receive 40 mg subcutaneous injections of either CinnoRA® or Humira® every other week, while receiving methotrexate (15 mg/week), folic acid (1 mg/day), and prednisolone (7.5 mg/day) over a period of 24 weeks. Physical examinations, vital sign evaluations, and laboratory tests were conducted in patients at baseline and at 12-week and 24-week visits. The primary endpoint in this study was the proportion of patients achieving moderate and good disease activity score in 28 joints-erythrocyte sedimentation rate (DAS28-ESR)-based European League Against Rheumatism (EULAR) response. The secondary endpoints were the proportion of patients achieving American College of Rheumatology (ACR) criteria for 20% (ACR20), 50% (ACR50), and 70% (ACR70) responses along with the disability index of health assessment questionnaire (HAQ), and safety. RESULTS Patients who were randomized to CinnoRA® or Humira® arms had comparable demographic information, laboratory results, and disease characteristics at baseline. The proportion of patients achieving good and moderate EULAR responses in the CinnoRA® group was non-inferior to the Humira® group at 12 and 24 weeks based on both intention-to-treat (ITT) and per-protocol (PP) populations (all p values >0.05). No significant difference was noted in the proportion of patients attaining ACR20, ACR50, and ACR70 responses in the CinnoRA® and Humira® groups (all p values >0.05). Further, the difference in HAQ scores and safety outcome measures between treatment arms was not statistically significant. CONCLUSION CinnoRA® was shown to be non-inferior to Humira® in terms of efficacy at week 24 with a comparable safety profile to the reference product.

Efficacy and Safety of Subcutaneous Golimumab in Methotrexate-Naive Patients With Rheumatoid Arthritis: Five-Year Results of a Randomized Clinical Trial. Arthritis Care Res (Hoboken) 2017; 68:744-52. [PMID: 26474452 PMCID: PMC5089605 DOI: 10.1002/acr.22759] [Citation(s) in RCA: 31] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2015] [Accepted: 10/06/2015] [Indexed: 11/29/2022]
Abstract
Objective To evaluate the safety and efficacy of golimumab through 5 years in adults with active rheumatoid arthritis (RA) who had not previously received methotrexate (MTX). Methods In the GO‐BEFORE study, 637 MTX‐naive adult patients with active RA were randomized (1:1:1:1) to placebo + MTX (group 1), golimumab 100 mg + placebo (group 2), golimumab 50 mg + MTX (group 3), or golimumab 100 mg + MTX (group 4). Inadequate responders in groups 1, 2, and 3 entered early escape at week 28 to golimumab 50 mg + MTX, golimumab 100 mg + MTX, or golimumab 100 mg + MTX, respectively; remaining patients in group 1 could cross over to golimumab 50 mg + MTX at week 52. Assessments included the American College of Rheumatology 20%/50%/70% improvement criteria (ACR20/50/70) response, the Disease Activity Score in 28 joints (DAS28) using C‐reactive protein (CRP) level, and the modified Sharp/van der Heijde score (SHS). Efficacy was analyzed using an intent‐to‐treat (ITT) analysis. Pharmacokinetics and immunogenicity were evaluated at selected visits. Results A total of 422 patients completed golimumab treatment through week 256. At week 256, 72.8%, 54.6%, and 38.0% of all patients in the full ITT population (n = 637) had an ACR20/50/70 response, respectively; 84.1% had a good or moderate DAS28‐CRP response; and 72.7% had a clinically meaningful improvement in physical function. Radiographic progression was minimal in all treatment groups through week 256, and the overall mean change from baseline in SHS was 1.36. Serum trough golimumab concentrations were approximately dose proportional and maintained through week 256. Antibodies to golimumab occurred in 9.6% of patients through week 256. Infections were the most common type of adverse event (AE); 204 of 616 patients (33.1%) had ≥1 serious AE. Conclusion Clinical efficacy with golimumab treatment was maintained through week 256 of the GO‐BEFORE trial of MTX‐naive RA patients. No unexpected AEs occurred; safety results through 5 years are consistent with earlier reports.

Abstract
BACKGROUND To examine how closely reporting rates in the FDA Adverse Event Reporting System (FAERS) reflect expected rates of known adverse drug events (ADEs). METHODS We selected three groups of drugs to reflect hypothesized variation in sensitivity to reporting, including statins, biologics, and narrow therapeutics index drugs (NTI). The numbers of ADEs in FAERS were divided by utilization estimates from ambulatory health care data (NAMCS/NHAMCS) to calculate a reported proportion. One sample z-test for proportions compared the proportion of ADEs reported to an expected ADE proportion derived from drug labels, reference databases, and peer-reviewed papers. RESULTS The majority of drug-ADE pairs showed significant under-reporting. For example, roughly 0.01% to 44% of statin events were reported (z-test p < 0.0001). Biological (0.002% to >100%) and NTI (20% to >100%) drugs had relatively higher reporting rates. Roughly 20% to 33% of the minimum number of expected serious events were reported with biologics and NTI drugs. CONCLUSIONS This study supports previous evidence of under-reporting of ADEs in spontaneous reporting data. But, under-reporting varies considerably by the type of drug and the type of ADEs, and this variability in under-reporting should be considered when interpreting safety signals.

Long-Term Maintenance of Certolizumab Pegol Safety and Efficacy, in Combination with Methotrexate and as Monotherapy, in Rheumatoid Arthritis Patients. Rheumatol Ther 2017; 4:57-69. [PMID: 28353191 PMCID: PMC5443729 DOI: 10.1007/s40744-017-0060-8] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2017] [Indexed: 01/22/2023] Open
Abstract
INTRODUCTION The safety and efficacy of certolizumab pegol (CZP) 400 mg every 4 weeks (Q4W) monotherapy (FAST4WARD/NCT00548834) and in combination with methotrexate (MTX) (014/NCT00544154) in active rheumatoid arthritis (RA) has been published previously. This report outlines final long-term outcomes from the open-label extension (OLE) study (015/NCT00160693), which enrolled patients from these randomized controlled trials (RCTs). METHODS Patients who withdrew from or completed the 24-week 014/FAST4WARD RCTs were enrolled and received CZP 400 mg Q4W with/without MTX. Exposure-adjusted event rates (ER) per 100 patient-years (PYs) of adverse events (AEs) and serious AEs (SAEs) were reported for all patients receiving ≥1 dose of CZP in RCTs or OLE (N = 427) between first CZP dose and up to 24 weeks after last CZP dose or study withdrawal. Efficacy assessments included clinical (ACR20/50/70 response rates, TJC, SJC) and patient-reported outcomes (HAQ-DI, PtGADA, pain, fatigue) to week 304 (5.8 years) in the CZP intent-to-treat population. SDAI and CDAI outcomes were analyzed post hoc. Outcomes for CZP monotherapy and CZP+MTX combination-therapy were compared. RESULTS Globally, ERs of AEs and SAEs were 408.1 and 25.2 per 100 PY, respectively. Eleven patients had AEs leading to death (ER 0.6). Improvements in clinical and patient-reported outcomes during the 24-week RCTs were maintained to week 304, and were similar between all subpopulations. CONCLUSIONS The longest exposure duration to date with CZP 400 mg Q4W treatment confirmed the safety profile observed in previous studies. Initial improvements in signs and symptoms of RA, including PROs, were maintained in both CZP monotherapy and CZP + MTX combination-therapy patients.

Do tumor necrosis factor inhibitors increase cancer risk in patients with chronic immune-mediated inflammatory disorders? Cytokine 2016; 101:78-88. [PMID: 27688201 DOI: 10.1016/j.cyto.2016.09.013] [Citation(s) in RCA: 35] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2016] [Revised: 09/17/2016] [Accepted: 09/19/2016] [Indexed: 02/05/2023]
Abstract
Inhibition of tumor necrosis factor (TNF) activity has profoundly changed the management of several immune-mediated inflammatory diseases with great benefit for patients. The application of TNF inhibitors (TNFi), however, also brings a new concern, malignancy. We performed a systemic review to collect the studies reporting cancer incidences and risks in TNFi users regardless of indications. TNFi were most frequently used in treating patients with rheumatoid arthritis (RA) and inflammatory bowel diseases (IBD). In RA patients without prior cancer history, the incidences of malignancies ranged from the lowest rate 0 per 1000 person-years in etanercept users regarding lymphoma to the highest rate 35.62 per 1000 person-years in adalimumab users on non-melanoma skin cancer (NMSC), while in those patients with prior cancer history, the recurrent incidences of malignancies ranged from the lowest rate 5.05 per 1000 person-years regarding melanoma to the highest rate 63.20 per 1000 person-years on basal cell carcinoma (BCC) in TNFi users. In IBD patients, incidences ranged from 0 per 1000 person-years in TNFi users on lymphoma to 34.0 per 1000 person-years in infliximab users on overall cancer. However, these incidence rates of overall cancer, lymphoma and melanoma were not higher in comparison with those patients who were not treated with TNFi. Compared to general population, incidences of lymphoma were elevated in RA patients and rates of NMSC were higher in patients with psoriasis, RA and IBD. In conclusion, cancer incidences vary across different studies, indications, cancer types and studies with different individual TNFi. Treatment with TNFi is not associated with increased malignant risks of overall cancer, lymphoma or melanoma. Results of NMSC risk were inconsistent among studies. A latest prospective registry study demonstrated a small increased risk of squamous cell cancer in RA patients treated with TNFi (one additional case for every 1600years of treatment experience). Further prospective studies are needed to verify whether TNFi users have higher NMSC risk than non-TNFi users.

Abstract
AIM Adalimumab effectiveness on clinical, functional and work-related outcomes was evaluated in patients with active ankylosing spondylitis or psoriatic arthritis treated in routine clinical practice in central-eastern Europe. METHODS Patients (n = 555) were followed for 12 months. Primary end point was percentage of patients with a treatment response (≥50% decrease from baseline in Bath Ankylosing Spondylitis Disease Activity Index or ≥1.2 point decrease from baseline in Disease Activity Index-28 joint for axial or peripheral symptoms, respectively). Functional status was evaluated by the Bath Ankylosing Spondylitis Functional Index and Health Assessment Questionnaire Disability Index. Working ability was evaluated by the Work Productivity and Activity Impairment Questionnaire - Specific Health Problem. RESULTS 76.1% of patients with axial symptoms and 83.5% with peripheral symptoms achieved a treatment response. Frequency of extra-articular manifestations decreased. Improvements were observed in functional status and workability. No new safety signals were observed. CONCLUSION Adalimumab was effective and well tolerated during real-world use in central-eastern Europe.

Abstract
Introduction As patients with rheumatoid arthritis (RA) receive treatment with anti-tumour necrosis factors over several years, it is important to evaluate their long-term safety and efficacy. The objective of this study was to examine the safety and benefits of certolizumab pegol (CZP)+methotrexate (MTX) treatment for almost 5 years in patients with RA. Methods Patients who completed the 24-week Rheumatoid Arthritis Prevention of Structural Damage (RAPID) 2 randomized controlled trial (RCT; NCT00160602), or who were American College of Rheumatology (ACR) 20 non-responders at Week 16, entered the open-label extension (OLE; NCT00160641). After ≥6 months treatment with CZP 400 mg every two weeks (Q2W), dose was reduced to 200 mg Q2W, the approved maintenance dose. Safety data are presented from all patients who received ≥1 dose CZP (Safety population, n=612). Efficacy data are presented to Week 232 for the intent-to-treat (ITT, n=492) and Week 24 CZP RCT Completer (n=342) populations, and through 192 weeks of dose-reduction for the Dose-reduction population (patients whose CZP dose was reduced to 200 mg, n=369). Radiographic progression (modified total Sharp score change from RCT baseline >0.5) to Week 128 is reported for the Week 24 CZP Completers. Results In the RCT, 619 patients were randomized to CZP+MTX (n=492) or placebo+MTX (n=127). Overall, 567 patients (91.6%) entered the OLE: 447 CZP and 120 placebo patients. Of all randomized patients, 358 (57.8%) were ongoing at Week 232. Annual drop-out rates during the first four years ranged from 8.4–15.0%. Event rates per 100 patient-years were 163.0 for adverse events (AEs) and 15.7 for serious AEs. Nineteen patients (3.1%) had fatal AEs (incidence rate=0.8). Clinical improvements in the RCT were maintained to Week 232 in the CZP Completers: mean Disease Activity Score 28 (Erythrocyte Sedimentation Rate) change from baseline was −3.4 and ACR20/50/70 responses 68.4%/47.1%/25.1% (non-responder imputation). Similar improvements observed in the ITT were maintained following dose-reduction. 73.2% of CZP Completers had no radiographic progression at Week 128. Conclusions In patients with active RA despite MTX therapy, CZP was well tolerated, with no new safety signals identified. CZP provided sustained improvements in clinical outcomes for almost 5 years. Trial registration ClinicalTrials.gov, NCT00160602 and NCT00160641. Registered 8 September 2005.

Abstract
OBJECTIVE To evaluate the long-term effectiveness and safety of 10 years of adalimumab (ADA) treatment in DMARD-refractory RA patients and to analyse efficacy based on RF status and baseline disease duration. METHODS DE020 was a multicentre, phase 3, open-label continuation study. Adult RA patients who received s.c. ADA (40 mg every other week or monthly) in one of four early assessment studies could receive ADA for ≤10 years in DE020. Assessments included the 28-joint DAS with CRP (DAS28-CRP), Simplified Disease Activity Index (SDAI), HAQ Disability Index (HAQ-DI) and safety as events per 100 patient-years. RESULTS Of 846 enrolled patients, mean age at baseline was 55.6 years, 78.1% were women, mean disease duration was 11.7 years and 27.0% were RF(-). Among 286 (33.8%) patients who completed 10 years of ADA, 168/236 (71.2%) achieved DAS28-CRP ≤3.2, 101/238 (42.4%) achieved HAQ-DI <0.5 and 90/241 (37.3%) achieved DAS28-CRP ≤3.2 plus HAQ-DI <0.5. DAS28-CRP- or SDAI-based remission was observed in 135/236 (57.2%) and 70/236 (29.7%) patients, respectively. Effectiveness outcomes were similar regardless of RF status. Higher proportions of patients with shorter vs longer baseline disease duration (≤2 vs >2 years) achieved HAQ-DI <0.5 (60.6% vs 39.5%; P = 0.023) and DAS28-CRP ≤3.2 plus HAQ-DI <0.5 (58.1% vs 32.5%; P = 0.006). Adverse events (317.2 events per 100 patient-years) during ADA exposure were consistent with the expected safety profile for TNF inhibitors. CONCLUSION ADA led to sustained clinical and functional responses in the 33.8% of treatment-refractory RA patients who completed 10 years of treatment. Patients with shorter disease duration achieved better outcomes, highlighting the need for early treatment. No unexpected safety findings were observed.

Abstract
OBJECTIVE To estimate cost per patient-year in response during 2 years following biologic initiation among patients with rheumatoid arthritis (RA). METHODS Adults newly initiating biologics for RA (etanercept, abatacept, adalimumab, certolizumab, golimumab, or infliximab) between January 2009 and July 2011 were identified in the MarketScan Commercial Database. Eligible patients were continuously enrolled 6 months before (pre-index) and 24 months after (post-index) their first (index) biologic claim. Biologic effectiveness was assessed using six criteria during 2-year follow-up: treatment adherence ≥80%, no biologic dose escalation, no biologic switch, no new disease-modifying anti-rheumatic drug, no new/increased glucocorticoid dose, and limited intra-articular joint injections (≤2). After a 90-day period of non-response for a treatment failure, effectiveness or failure of subsequent treatment was assessed again for the index biologic or new biologic (after switching). Post-index RA-related medical, pharmacy, and drug administration costs were attributed to the index biologic. Cost per patient-year in response was calculated as RA-related costs divided by duration of response. RESULTS Overall, 15.0% of patients (1229/8193) did not fail any criterion for 2 years and were effectively treated. Mean duration of response was highest for etanercept (538.3 days), followed by golimumab (537.0 days; p = 0.864), adalimumab (534.7 days; p = 0.301), certolizumab (524.0 days; p = 0.165), infliximab (480.0 days; p < 0.001), and abatacept (482.3 days; p < 0.001). Total disease-related cost per patient-year in response was lower for patients initiated on etanercept ($25,086) than for patients initiated on adalimumab ($25,960), certolizumab ($26,339), golimumab ($26,332), abatacept ($35,581), or infliximab ($36,107). LIMITATIONS This study was limited to employer-paid commercial insurance. Database analyses cannot determine reasons for failing criteria. The algorithm was not designed and validated for 2 years of follow-up. CONCLUSIONS An effectiveness algorithm estimated that initiating etanercept was the most effective treatment during 2 years of follow-up, with the lowest cost per patient-year in response.
