Etanercept (ETN) is a disease-modifying anti-rheumatic drug (DMARD) used in the treatment of rheumatoid arthritis (RA) that works as a tumor necrosis factor inhibitor (TNF inhibitor) by blocking the effects of naturally occurring TNF. This review will evaluate the effect of ETN as a monotherapy or combination therapy with methotrexate (MTX) in the treatment of RA. This systematic review was carried out in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) 2020 guidelines. A systematic search was done on PubMed and Google Scholar from 1999 to 2023. Predefined eligibility criteria were set for selected studies, which include: free full-text articles published; randomized control trials (RCTs); systematic reviews and meta-analyses; and observational studies in a patient with RA treated with ETN as initial therapy or as an add-on to conventional disease-modified therapy. Hence, the data had been extracted, and a quality assessment of each study was done by two individual authors. When comparing patients who received 15-25 mg of MTX with those who also received 25 mg of ETN in combination, 71% achieved American College of Rheumatology 20 (ACR20) by 24 weeks, compared to 27% in the MTX and placebo groups (p<0.001), and 39% achieved American College of Rheumatology 50 (ACR50), compared to 3% in the placebo + MTX group (p<0.001). Low disease activity (DAS 28) was more common in patients who had both MTX and ETN (64.5% with DAS <2.4 and 56.3% with DAS 28 <3.2) compared to patients who received only one medication (44.4% with DAS <2.4 and 33.2% with DAS 28 <3.2 for ETN and 38.6% with DAS <2.4 and 28.5% with DAS 28 <3.2 for MTX, with P<0.01). ETN demonstrated smaller changes from baseline in the modified Sharp score (TSS) and erosion scores (ES) at 12 months and two years, as well as a decreased change in the ES score at one year (with a trend of P value = 0.06 for the TSS score), in comparison to those receiving DMARD. Reactions at the injection site (42% vs. 7%, P<0.001) were the only events that occurred significantly more frequently in the ETN plus-MTX group. Combining ETN and MTX appears to help control RA symptoms by decreasing the American College of Rheumatology (ACR) response and DAS score, as well as halting the disease's progression on X-rays. The most common adverse effects were reactions to ETN administered alone at the injection site, likely because of patient awareness of the treatment received. There was also concern about tuberculosis and malignancy, but no recent data is available. Therefore, a larger clinical trial with longer follow-up is required to ascertain long-term safety and benefits.

BACKGROUND: Rheumatoid arthritis (RA) is a chronic autoimmune disease dominated by chronic inflammation of the synovium of the joints. Methotrexate (MTX) is the most widely used in the treatment of RA. This study systematically evaluated the clinical efficacy of MTX on RA and provided a theoretical basis for the clinical treatment of RA. METHODS: Four English databases (PubMed, Embase, Medline, and Web of Sciences) were searched for randomized controlled trials (RCTs) on MTX treatment of RA published from the date of establishment of the database to 2021. The Cochrane Handbook 5.0.2 was used to perform risk bias evaluation and Review Manager 5.3 was used to conduct a meta-analysis. RESULTS: A total of eight articles were included. The meta-analysis showed that, compared to the control group, the number of patients with DAS28-ESR ≤2.6 [erythrocyte sedimentation rate (ESR)] in the MTX alone or MTX combined treatment groups was higher, and the incidence of adverse events was also higher. However, there was no significant difference in the level of alanine aminotransferase (ALT) after treatment versus the control group. DISCUSSION: MTX alone or MTX combined treatment can better control the condition of RA patients without causing damage to the patient's blood system or liver and kidney function, but may increase the probability of adverse events.

OBJECTIVES: To inform the 2019 update of the European League against Rheumatism (EULAR) recommendations for the management of rheumatoid arthritis (RA). METHODS: A systematic literature research (SLR) to investigate the efficacy of any disease-modifying antirheumatic drug (DMARD) (conventional synthetic (cs)DMARD, biological (b) and biosimilar DMARD, targeted synthetic (ts)DMARD) or glucocorticoid (GC) therapy in patients with RA was done by searching MEDLINE, Embase and the Cochrane Library for articles published between 2016 and 8 March 2019. RESULTS: 234 abstracts were selected for detailed assessment, with 136 finally included. They comprised the efficacy of bDMARDs versus placebo or other bDMARDs, efficacy of Janus kinase (JAK) inhibitors (JAKi) across different patient populations and head-to-head of different bDMARDs versus JAKi or other bDMARDs. Switching of bDMARDs to other bDMARDs or tsDMARDs, strategic trials and tapering studies of bDMARDs, csDMARDs and JAKi were assessed. The drugs evaluated included abatacept, adalimumab, ABT-122, baricitinib, certolizumab pegol, SBI-087, CNTO6785, decernotinib, etanercept, filgotinib, golimumab, GCs, GS-9876, guselkumab, hydroxychloroquine, infliximab, leflunomide, mavrilimumab, methotrexate, olokizumab, otilimab, peficitinib, rituximab, sarilumab, salazopyrine, secukinumab, sirukumab, tacrolimus, tocilizumab, tofacitinib, tregalizumab, upadacitinib, ustekinumab and vobarilizumab. The efficacy of many bDMARDs and tsDMARDs was shown. Switching to another tumour necrosis factor inhibitor (TNFi) or non-TNFi bDMARDs after TNFi treatment failure is efficacious. Tapering of DMARDs is possible in patients achieving long-standing stringent clinical remission; in patients with residual disease activity (including patients in LDA) the risk of flares is increased during the tapering. Biosimilars are non-inferior to their reference products. CONCLUSION: This SLR informed the task force regarding the evidence base of various therapeutic regimen for the development of the update of EULAR's RA management recommendation.

OBJECTIVES: The aim of this study was to estimate the effectiveness of first-line biologic disease modifying drugs(boDMARDs), and their approved biosimilars (bsDMARDs), compared with conventional (csDMARD) treatment, in terms of ACR (American College of Rheumatology) and EULAR (European League against Rheumatism) responses. METHODS: Systematic literature search, on eight databases to January 2017, sought ACR and EULAR data from randomized controlled trials (RCTs) of boDMARDs / bsDMARDs (in combination with csDMARDs, or monotherapy). Two adult populations: methotrexate (MTX)-naïve patients with severe active RA; and csDMARD-experienced patients with moderate-to-severe active RA. Network meta-analyses (NMA) were conducted using a Bayesian Markov chain Monte Carlo simulation using a random effects model with a probit link function for ordered categorical. RESULTS: Forty-six RCTs met the eligibility criteria. In the MTX-naïve severe active RA population, no biosimilar trials meeting the inclusion criteria were identified. MTX plus methylprednisolone (MP) was most likely to achieve the best ACR response. There was insufficient evidence that combination boDMARDs was superior to intensive (two or more) csDMARDs. In the csDMARD-experienced, moderate-to-severe RA population, the greatest effects for ACR responses were associated with tocilizumab (TCZ) monotherapy, and combination therapy (plus MTX) with bsDMARD etanercept (ETN) SB4, boDMARD ETN and TCZ. These treatments also had the greatest effects on EULAR responses. No clear differences were found between the boDMARDs and their bsDMARDs. CONCLUSIONS: In MTX-naïve patients, there was insufficient evidence that combination boDMARDs was superior to two or more csDMARDs. In csDMARD-experienced patients, boDMARDs and bsDMARDs were comparable and all combination boDMARDs / bsDMARDs were superior to single csDMARD.

Introduction Early biological treatment of rheumatoid arthritis (RA) may reverse the autoimmune response in some patients resulting in favorable long-term outcomes. Although the cost-effectiveness of this strategy has been questioned, biosimilar entries warrant the revision of clinical and pharmaco-economic evidence. Areas covered We conducted a systematic review of randomized controlled trials (RCTs) published up to 24th May 2018 in Pubmed, EMBASE and Cochrane CENTRAL, comparing infliximab with non-biological therapy in patients with RA naïve to methotrexate. We performed meta-analyses for efficacy outcomes at month 6 and years 1 and 2. Six RCTs were identified, involving 1832 patients. At month 6 ACR70 response and remission, and at year 1 ACR20/ACR70 responses and remission were improved significantly with first-line infliximab versus control. The differences were not significant at year 2. We reviewed cost-utility studies, up to October 31, 2018 in PubMed, Cochrane CENTRAL and the CRD HTA databases. Four studies indicated that first-line use of originator infliximab calculated at 2005-2008 prices was not cost-effective. Expert opinion We demonstrated the efficacy benefits of first-line infliximab therapy up to 1 year in methotrexate-naïve RA. We highlighted the need for standardized reporting of outcomes and conducting cost-effectiveness analyses of first-line biosimilar therapy in RA.

OBJECTIVES: To assess the efficacy and safety of methotrexate (MTX) in combination with an approved biological agent compared to biological monotherapy, in the management of patients with rheumatoid arthritis (RA). METHODS: MEDLINE, EMBASE, CENTRAL and other sources were searched for randomised trials evaluating a biological agent plus MTX versus the same biological agent in monotherapy. Co-primary outcomes were ACR50 and the number of patients who discontinued due to adverse events (AEs). Random-effects models were applied for meta-analyses with risk ratio and 95% confidence intervals and the GRADE approach was used to assess confidence in the estimates. RESULTS: The analysis comprised 16 trials (4965 patients), including all biological agents approved for RA except anakinra and certolizumab. The overall likelihood of responding to therapy (i.e. ACR50) after 6 months was 32% better when MTX was given concomitantly with biological agents (1.32 [1.20-1.45]; P < 0.001) corresponding to 11 more out of 100 patients (7-16 more); Moderate Quality Evidence. Discontinuing due to AEs from concomitant use of MTX was potentially 20% increased (1.21 [0.97-1.50]; P = 0.09) compared to biological monotherapy corresponding to 1 more out of 100 patients (0-3 more); Moderate Quality Evidence. CONCLUSIONS: Randomised trials provide Moderate Quality Evidence for a favourable benefit-harm balance supporting concomitant use of MTX rather than monotherapy when prescribing a biological agent in patients with RA although in absolute terms only 7-16 more out of 100 patients will achieve an ACR50 response after 6 months of this combination therapy.

INTRODUCTION: Synthesis of evidence on the long-term use of first-line biologic therapy in patients with early rheumatoid arthritis (RA) is required. We compared the efficacy of up to 5 years' treatment with first-line tumor necrosis factor inhibitors (TNFis) versus other treatment strategies in this population. METHODS: Previous systematic reviews, PubMed and the Cochrane Central Register of Controlled Trials were searched for randomized controlled trials (RCTs) involving treatment of methotrexate-naïve RA patients with first-line TNFis. Literature was synthesized qualitatively, and a meta-analysis conducted to evaluate American College of Rheumatology (ACR) responses, clinical remission defined by any standard measure, and Health Assessment Questionnaire Disability Index (HAQ) at Years 2 and/or 5. RESULTS: Ten RCTs involving 4306 patients [first-line TNFi, n = 2234; other treatment strategies (control), n = 2072] were included in the meta-analysis. Three studies were double-blind for the first 2 years, while seven were partly/completely open label during this period. Five studies reported data at Year 5; all were open label at this time point. At Year 2, ACR50 response, ACR70 response and remission rates were significantly improved with first-line TNFi versus control in double-blind RCTs [log-odds ratio (OR) 0.32 [95% confidence interval (CI) 0.02, 0.62; p = 0.035], log-OR 0.48 (95% CI 0.20, 0.77; p = 0.001), and log-OR 0.44 (95% CI 0.13, 0.74; p = 0.005), respectively], but not in open-label studies. No significant between-group differences were observed in mean HAQ at Year 2 in double-blind or open-label RCTs or in ACR response or remission outcomes at Year 5. CONCLUSION: In double-blind studies, 2-year efficacy outcomes were significantly improved with first-line TNFi versus other treatment strategies in patients with MTX-naïve RA. No significant differences in these outcomes were observed when data from open-label RCTs were considered on their own. Further data on the efficacy of TNFi therapy over ≥ 2 years in patients with methotrexate-naïve RA are required. Plain language summary available for this article.

The effect of five approved tumour necrosis factor inhibitors (TNFi: infliximab, etanercept, adalimumab, certolizumab, and golimumab) on joint destruction in rheumatoid arthritis (RA) have been compared versus methotrexate (MTX) in randomized controlled trials (RCTs) but have not been compared directly to each other or to an otherwise untreated placebo control. The present analysis compares effects of standard doses, high doses, and low doses of TNFis on radiographic joint destruction in RA and relate these effects to MTX and placebo by means of a Bayesian network meta-analysis. We identified 31 RCTs of the effect of TNFis on joint destruction and 5 RCTs with controls, which indirectly could link otherwise untreated placebo controls to the TNFi treatments in the network. The previously untested comparison with placebo was performed to estimate not only the effect relative to another drug, but also the absolute attainable effect. Compared to placebo there was a highly significant inhibitory effect on joint destruction of infliximab, etanercept, adalimumab, certolizumab, and golimumab, which was about 0.9% per year as monotherapy and about 1.2% per year when combined with MTX. Although significantly better than MTX and placebo, golimumab seemed inferior to the remaining TNFis. There was no difference between original reference drugs (Remicade, Enbrel) and the almost identical copy drugs (biosimilars).

Background: The mainstream medications for rheumatoid arthritis (RA) include conventional disease-modifying antirheumatic drugs (cDMARDs), which mostly are methotrexate (MTX), and biologic agents such as adalimumab (ADA), certolizumab (CZP), etanercept (ETN), golimumab (GOL), infliximab (IFX), and tocilizumab (TCZ). This network meta-analysis was aimed at evaluating the efficacy and safety of the medications above and interventions combining cDMARDs and biologic agents for patients with RA. Methods: PubMed, EMBASE, Cochrane Library, and ClinicalTrials.gov were searched systematically for eligible randomized controlled trials (RCTs). Outcomes concerning efficacy and safety were evaluated utilizing odds ratios (ORs) and 95% credible intervals (CrI). The outcomes of efficacy would be evaluated through remission and American College of Rheumatology (ACR) scores. The surface under the cumulative ranking curve (SUCRA) was calculated to rank each treatment on each index. Results: A total of 20 RCTs with 9,047 patients were included, and the efficacy and safety of the concerning interventions for RA were evaluated. Compared with cDMARDs alone, TCZ+MTX, ETN+MTX, IFX+MTX, TCZ, and ADA+MTX showed significant statistical advantage on ACR20, ACR50, and ACR70. Apart from that, as for remission, TCZ+MTX, IFX+MTX, TCZ, and CZP+MTX performed better compared to cDMARDs alone. The SUCRA ranking also indicated that TCZ+MTX was the intervention with best ranking in the entire four efficacy indexes followed by ETX+MTX and IFX+MTX. However, there was no obvious difference among these medications compared with cDMARDs when it comes to safety, which need more specific studies on that. Conclusion: TCZ+MTX was potentially the most recommended combination of medications for RA due to its good performance in all outcomes of efficacy. ETX+MTX and IFX+MTX, which also performed well, could be introduced as alternative treatments. However, considering the adverse events, the treatments concerning should be introduced with caution.

OBJECTIVES: Compare the benefits and harms of drug therapies for adults with early rheumatoid arthritis (RA) within 1 year of diagnosis, updating the findings on early RA from the 2012 review. DATA SOURCES: English-language articles identified through MEDLINE®, Cochrane Library, Embase®, International Pharmaceutical Abstracts, gray literature, the previous 2012 review, expert recommendations, reference lists of published literature, and supplemental evidence data requests from January 2011 to October 5, 2017. REVIEW METHODS: Literature was synthesized qualitatively in narrative form and summary tables within and between corticosteroids and classes of disease-modifying antirheumatic drugs (DMARDs). Additionally, combination treatment strategies were examined. We conducted network meta-analysis for five outcomes: American College of Rheumatology 50-percent improvement (ACR50), remission based on Disease Activity Score (DAS), radiographic joint damage, all discontinuations, and discontinuations due to adverse events. Eligibility for network meta-analyses required the following: (1) patients with early RA had not attempted prior treatment with methotrexate (MTX), (2) doses of treatments were within ranges approved by the Food and Drug Administration (FDA), (3) length of followup was similar, and (4) studies were double-blinded randomized controlled trials of low or medium risk of bias. RESULTS: We analyzed 49 studies: 41 RCTs and 8 observational studies reported in 124 published articles. All included studies enrolled patients with moderate to high disease activity at baseline as measured with mean or median DAS 28 scores. A combination of corticosteroids plus MTX achieved higher remission rates than with MTX monotherapy (low strength of evidence [SOE]). Combination therapy with TNF (tumor necrosis factor) or non-TNF biologics plus MTX improved disease control, remission, and functional capacity compared with monotherapy with either MTX or a biologic (low to moderate SOE). Network meta-analyses found higher ACR50 response for combination therapy of biologics plus MTX than for MTX monotherapy (range of relative risk, 1.20 [95% confidence interval (CI), 1.04 to 1.38] to 1.57 [95% CI, 1.30 to 1.88]). In available data, consisting mostly of clinical trials, no significant differences emerged between any DMARDs for rates of discontinuation attributable to adverse events or serious adverse events (low SOE for adalimumab, certolizumab pegol, etanercept, infliximab, or abatacept with MTX, and moderate SOE for rituximab or tocilizumab with MTX). Data about subgroups (based on disease activity, prior therapy, demographics, and the presence of other serious conditions) were insufficient. No difference in findings were noted in MTX naïve and resistant populations. We found no studies of biosimilars for patients with early RA. CONCLUSIONS: Qualitative synthesis and network meta-analyses suggest that the combination of MTX with TNF or non-TNF biologics improves disease activity and remission when compared with biologic monotherapy or a conventional synthetic DMARD (csDMARD) monotherapy in patients with moderate to high disease activity at baseline as measured with mean or median DAS 28 scores. Overall rates of adverse events and discontinuation were similar among patients given csDMARDs, TNF biologics, and non-TNF biologics. We did not find eligible studies of biosimilars.
