A 24-week randomized clinical trial investigating the efficacy and safety of two doses of etanercept in nail psoriasis

Nail psoriasis is common in patients with psoriasis and can seriously affect their quality of life. Current treatments are limited and there is no standard course of therapy. To assess the efficacy and safety of etanercept (ETN) on nail psoriasis in patients with moderate-to-severe psoriasis. Patients with moderate-to-severe plaque psoriasis, who had previously failed at least one form of systemic therapy for nail psoriasis, were randomized to receive open-label ETN 50 mg twice weekly (BIW) for 12 weeks followed by once weekly (QW) for 12 weeks (BIW/QW group) or ETN 50 mg QW for 24 weeks (QW/QW group). The primary endpoint was the mean improvement in the Nail Psoriasis Severity Index (NAPSI; score range 0-8) over 24 weeks in the target fingernail with the most severe abnormalities. Seventy-two patients received one or more doses of ETN (38 BIW/QW; 34 QW/QW) and 69 patients were included in the modified intent-to-treat population. At baseline, mean (standard error) target fingernail NAPSI score was 6.0 (0.3) in the BIW/QW group and 5.8 (0.3) in the QW/QW group. At week 24, mean target fingernail NAPSI score had decreased significantly by -4.3 [95% confidence interval (CI) -4.9 to -3.7; P < 0.0001] in the BIW/QW group and by -4.4 (95% CI -5.0 to -3.7; P < 0.0001) in the QW/QW group. Improvement in NAPSI showed significant correlation with Psoriasis Area and Severity Index improvement. ETN was well tolerated with no unexpected safety findings. Both ETN regimens were effective at treating nail psoriasis in this patient population.

Clinical trial of etanercept tapering in juvenile idiopathic arthritis during remission

To explore the possibility of step-down method and low dose of etanercept for long-term stable remission of patients with juvenile idiopathic arthritis (JIA). Patients with JIA were enrolled into this study between February 2008 and March 2010 and then followed up for 2 years. The inclusion criteria were clinical remission and use of etanercept for therapy. On the first year of the study, the dose of etanercept was kept at 0.4 mg/kg per week, the half dose of what those patients had been used. On the second year, the dose of etanercept was further lowered to 0.4 mg/kg per month. DMARDs were allowed in this study. MR images were performed to observe joint changes. The primary end point was disease flare defined according to clinical and/or radiological data. The flare rate curve was analyzed by Kaplan-Meier, and logistic regression model was used to find factors associating with disease flare. MRI was performed to prove no active changes or progressions of bone erosions on joints. Thirty-one patients were enrolled in this study. There were 4 patients experiencing disease flare during the first 12th month. During the second year, disease flare was not occurred. Thus, the cumulative flare rate was 12.9 % on 12th month and then unchanged on the second year. Logistic regression model indicates there are no differences in sex, age of disease initiation, disease duration, subtypes, DMARDs, HLA-B27, months of etanercept duration and scores on MRI between patients with remission and those experiencing flares. At the end of the study, MRI found no progressions of joints to the patients keeping stable remission. Step-down method can be used for etanercept tapering. Long-term remission and low flare rate can be got by this method.

Maintenance, reduction, or withdrawal of etanercept after treatment with etanercept and methotrexate in patients with moderate rheumatoid arthritis (PRESERVE): a randomised controlled trial

Clinical remission and low disease activity are essential treatment targets in patients with rheumatoid arthritis. Although moderately active rheumatoid arthritis is common, treatment effects in moderate disease have not been well studied. Additionally, optimum use of biologics needs further investigation, including the use of induction, maintenance, and withdrawal treatment strategies. The aim of the PRESERVE trial was to assess whether low disease activity would be sustained with reduced doses or withdrawal of etanercept in patients with moderately active disease. In a randomised controlled trial, patients aged between 18 and 70 years with moderately active rheumatoid arthritis (disease activity score in 28 joints [DAS28] >3.2 and ≤5.1) despite treatment with methotrexate were enrolled at 80 centres in Europe, Latin America, Asia, and Australia between March 6, 2008, and Sept 9, 2009. To be eligible, patients had to have been receiving 15-25 mg of methotrexate every week for at least 8 weeks. In an open-label period of 36 weeks, all patients were given 50 mg etanercept plus methotrexate every week. To be eligible for a subsequent double-blind period of 52 weeks, participants had to have achieved sustained low disease activity. These patients were randomly assigned (1:1:1) by an interactive voice-response system to one of three treatment groups: 50 mg etanercept plus methotrexate, 25 mg etanercept plus methotrexate, or placebo plus methotrexate. Patients were stratified in blocks of three by DAS28 response (low disease activity or remission) at week 36. Patients, investigators, data analysts, and study staff were all masked to treatment allocation. The primary endpoint was the proportion of patients with low disease activity at week 88 in the groups given 50 mg etanercept or placebo in the double-blind period. A conditional primary endpoint was the proportion of patients receiving 25 mg etanercept who achieved low disease activity. Modified intention-to-treat populations were used for analyses. This trial is registered with ClinicalTrials.gov, number NCT00565409. 604 (72.4%) of 834 enrolled patients were eligible for the double-blind period, of whom 202 were assigned to 50 mg etanercept plus methotrexate, 202 to 25 mg etanercept plus methotrexate, and 200 to placebo plus methotrexate. At week 88, 166 (82.6%) of 201 patients who had received at least one dose of 50 mg etanercept and one or more DAS28 evaluations had low disease activity, compared with 84 (42.6%) of 197 who had received placebo (mean difference 40.8%, 95% CI 32.5-49.1%; p<0.0001). Additionally, 159 (79.1%) of 201 patients given 25 mg etanercept had low disease activity at week 88 (mean difference from placebo 35.9%, 27.0-44.8%; p<0.0001). Conventional or reduced doses of etanercept with methotrexate in patients with moderately active rheumatoid arthritis more effectively maintain low disease activity than does methotrexate alone after withdrawal of etanercept.

Rheumatoid arthritis: still a chronic disease

For many years, few treatment options were available for patients with rheumatoid arthritis, leading to extensive joint damage and increased mortality compared with control groups. Progress in treatment of this chronic disease started in 1980 with the widespread use of methotrexate early in the disease course, followed by the first biological treatment to target the cytokine tumour necrosis factor (TNF) in 2000. 1 Klareskog L Catrina AI Paget S Rheumatoid arthritis. Lancet. 2009; 373: 659-672 Summary Full Text Full Text PDF PubMed Scopus (721) Google Scholar Presently, four anti-TNF monoclonal antibodies and one soluble receptor, etanercept, are marketed. Etanercept is a hybrid molecule composed of the soluble form of the type-2 p75 TNF receptor, which is linked to the fragment crystallisable region of IgG. Inhibition of TNF function results from the binding of TNF to etanercept. As a protein, etanercept is given systemically by subcutaneous self-administered injections of 50 mg once weekly. Methotrexate as a small chemical molecule can be taken orally, subcutaneously, or by intramuscular injection every week.

Duration of remission after halving of the etanercept dose in patients with ankylosing spondylitis: a randomized, prospective, long-term, follow-up study

BackgroundThe aim of this study was to evaluate the proportion of patients with ankylosing spondylitis maintaining clinical remission after reduction of their subcutaneous etanercept dose to 50 mg every other week compared with that in patients receiving etanercept 50 mg weekly.MethodsIn the first phase of this randomized, prospective, follow-up study, all biologic-naïve patients identified between January 2005 and December 2009 as satisfying the modified New York clinical criteria for ankylosing spondylitis treated with etanercept 50 mg weekly were evaluated for disease remission in January 2010. In the second phase, patients meeting the criteria for remission were randomized to receive subcutaneous etanercept as either 50 mg weekly or 50 mg every other week. The randomization allocation was 1:1. Remission was defined as Bath Ankylosing Spondylitis Disease Activity Index < 4, no extra-axial manifestations of peripheral arthritis, dactylitis, tenosynovitis, or iridocyclitis, and normal acute-phase reactants. The patients were assessed at baseline, at weeks 4 and 12, and every 12 weeks thereafter. The last visit constituted the end of the follow-up.ResultsDuring the first phase, 78 patients with ankylosing spondylitis (57 males and 21 females, median age 38 years, median disease duration 12 years) were recruited. In January 2010, after a mean follow-up of 25 ± 11 months, 43 (55.1%) patients achieving clinical remission were randomized to one of the two treatment arms. Twenty-two patients received etanercept 50 mg every other week (group 1) and 21 received etanercept 50 mg weekly (group 2). At the end of follow-up, 19 of 22 (86.3%) subjects in group 1 and 19 of 21 (90.4%) in group 2 were still in remission, with no significant difference between the two groups. The mean follow-up duration in group 1 and group 2 was 22 ± 1 months and 21 ± 1.6 months, respectively.ConclusionRemission of ankylosing spondylitis is possible in at least 50% of patients treated with etanercept 50 mg weekly. After halving of the etanercept dose, remission is maintained in a high percentage of patients during long-term follow-up, with important economic implications.

Clinical and economic efficiency to reduce dose etanercept and adalimumab in patients with rheumatoid arthritis

Methods A retrospective study on a cohort of 13 patients diagnosed rheumatoid artritis (RA) treated with anti-TNF (10 patients with etanercept, and 3 with adalimumab) and clinical remission (DAS28 < 2.6) in the last 6 months, in which reducing the dosing. This reduction was about 30% in both groups (etanercept passed from 25 mg twice a week to 25 mg every 5 days. In the case of Adalimumab it went from 40 mg to 40 mg every 2 weeks every 20 days. Clinical activity was evaluated by clinical activity index (DAS28), for functional capacity was used HAQ (Health Assessment Questionnaire). Others variables studied was visual analog scale (VAS). Analyzing before starting dose reduction, at 3 and 6 months.

Successful treatment of a patient with tumor necrosis factor receptor‐associated periodic syndrome using a half‐dose of etanercept

TNF receptor-associated periodic syndrome (TRAPS) is caused by mutations of TNFRSF1A gene and characterized by recurrent febrile episodes of prolonged duration and initial good response to steroids. Etanercept, a TNF blocker, has been used as a putative molecular-targeted agent for TRAPS, with some patients showing limited efficacy. Here, we report a patient with TRAPS who recovered from steroid dependency by etanercept and kept remission with a reduced dose of etanercept. The pathophysiology of TRAPS still remains to be elucidated and several hypotheses have been proposed. In the most recent hypothesis, the concerted action of wild-type and mutant TNF receptors plays an important role in provoking enhanced inflammation in TRAPS. The excellent response to etanercept in our patient suggested that there is heterogeneity in TRAPS patients in terms of the contribution of normal TNF signaling to autoinflammation.

Etanercept Concentration in Patients with Rheumatoid Arthritis and Its Potential Influence on Treatment Decisions: A Pilot Study

For patients with rheumatoid arthritis (RA), recommendations are inconclusive about whether tumor necrosis factor-α (TNF-α)-blocker therapy should be evaluated at 3 or 6 months. Biomarkers are needed to predict at 3 months which patients would benefit from further treatment because of nonoptimal response. Our objective was to investigate whether serum etanercept (ETN) concentrations and anti-ETN antibodies at 3 months are predictors of clinical response to ETN at 6 months in patients with RA in terms of European League Against Rheumatism criteria and Disease Activity Score in 28 joints (DAS28). Between 2009 and 2010, we included 19 women with active RA who were candidates for ETN therapy. Response criteria were evaluated at 3 and 6 months. Serum concentrations of ETN and anti-ETN antibodies were measured by ELISA at baseline and at 3 and 6 months. Eighteen patients completed followup. Three-month ETN concentrations were lower for 6-month nonresponders than responders (p = 0.03). Three-month ETN levels correlated significantly with change in DAS28 between baseline and 6 months (r = -0.62, p = 0.006). The best predictor of response at 6 months was observed with an ETN threshold of 3.1 μg/ml at 3 months. No anti-ETN antibodies were found. ETN concentrations at 3 months predict response to ETN therapy at 6 months. Low ETN concentrations could explain the absence of response to ETN, suggesting that patients with low ETN levels could benefit from increased ETN dose or earlier interruption of treatment.

Defining Patient Complexity

Background Perineural inhibitors of tumor necrosis factor have recently generated intense interest as an alternative to epidural steroid injections for lumbosacral radiculopathy. Objective To evaluate whether epidural steroids, etanercept, or saline better improves pain and function in adults with lumbosacral radiculopathy. Design A multicenter, 3-group, randomized, placebo-controlled trial conducted from 2008 to 2011. Randomization was computer-generated and stratified by site. Pharmacists prepared the syringes. Patients, treating physicians, and nurses assessing outcomes were blinded to treatment assignment. (ClinicalTrials.gov registration number: NCT00733096) Setting Military and civilian treatment centers. Patients 84 adults with lumbosacral radiculopathy of less than 6 months' duration. Intervention 2 epidural injections of steroids, etanercept, or saline, mixed with bupivacaine and separated by 2 weeks. Measurements The primary outcome measure was leg pain 1 month after the second injection. All patients had 1-month follow-up visits; patients whose condition improved remained blinded for the 6-month study period. Results The group that received epidural steroids had greater reductions in the primary outcome measure than those who received saline (mean difference, -1.26 [95% CI, -2.79 to 0.27]; P = 0.11) or etanercept (mean difference, -1.01 [CI, -2.60 to 0.58]; P = 0.21). For back pain, smaller differences favoring steroids compared with saline (mean difference, -0.52 [CI, -1.85 to 0.81]; P = 0.44) and etanercept (mean difference, -0.92 [CI,-2.28 to 0.44]; P = 0.18) were observed. The largest differences were noted for functional capacity, in which etanercept fared worse than the other treatments: steroids vs. etanercept (mean difference, -16.16 [CI, -26.05 to -6.27]; P = 0.002), steroids vs. saline (mean difference, -5.87 [CI, -15.59 to 3.85]; P = 0.23), and etanercept vs. saline (mean difference, 10.29 [CI, 0.55 to 20.04]; P = 0.04). More patients treated with epidural steroids (75%) reported 50% or greater leg pain relief and a positive global perceived effect at 1 month than those who received saline (50%) or etanercept (42%) (P = 0.09). Limitation Short-term follow-up, small sample size, and a possibly subtherapeutic dose of etanercept. Conclusion Epidural steroid injections may provide modest short-term pain relief for some adults with lumbosacral radiculopathy, but larger studies with longer follow-up are needed to confirm their benefits.

The efficacy and safety of etanercept when used with as-needed adjunctive topical therapy in a randomised, double-blind study in subjects with moderate-to-severe psoriasis (the PRISTINE trial)

Objective: To assess the efficacy and safety of two etanercept dose regimens for psoriasis treatment. Methods: Subjects were ≥18 years old with stable moderate-to-severe plaque psoriasis. Subjects were randomised to etanercept 50 mg once weekly (QW) or 50 mg twice weekly (BIW) double-blind for 12 weeks, followed by 50 mg QW open label in all subjects through week 24. Only mild topical corticosteroids were permitted on scalp, axillae and groin for first 12 weeks; topical medications (corticosteroids of all potencies, vitamin D analogues and combination products) were allowed as needed for second 12 weeks at physicians' discretion, consistent with “real-world” therapeutic practice. An independent ethics committee reviewed and approved the study protocol. Results: At week 24, 59.9% and 78.2% in the QW/QW and BIW/QW groups achieved PASI 75 improvement. Mean percentage PASI improvement in these groups was 58.5% and 74.1% at week 12 and 70.7% and 81.3% at week 24. Although permitted from weeks 12 to 24, topical agents were used in only 27.7% and 22.6% in the QW/QW and BIW/QW groups by week 24. Conclusion: Both etanercept regimens were efficacious in moderate-to-severe psoriasis, although the BIW/QW regimen consistently provided higher response rates than the QW/QW regimen. More potent topical medications were used electively in <25% of subjects in each group.

Epidural Steroids, Etanercept, or Saline in Subacute Sciatica

Active surveillance (AS) and watchful waiting (WW) have been proposed as management strategies for low-risk, localized prostate cancer. To systematically review strategies for observational management of prostate cancer (AS or WW), factors affecting their utilization, and comparative effectiveness of observational management versus immediate treatment with curative intent. MEDLINE and Cochrane databases (from inception to August 2011). Screened abstracts and reviewed full-text publications to identify eligible studies. One reviewer extracted data, and another verified quantitative data. Two independent reviewers rated study quality and strength of evidence for comparative effectiveness. Sixteen independent cohorts defined AS, 42 studies evaluated factors that affect the use of observational strategies, and 2 evidence reports and 22 recent studies reported comparisons of WW versus treatment with curative intent. The most common eligibility criteria for AS were tumor stage (all cohorts), Gleason score (12 cohorts), prostate-specific antigen (PSA) concentration (10 cohorts), and number of biopsy cores positive for cancer (8 cohorts). For monitoring, studies used combinations of periodic PSA testing (all cohorts), digital rectal examination (14 cohorts), and rebiopsy (14 cohorts). Predictors of receiving no active treatment included older age, comorbid conditions, lower Gleason score, tumor stage, PSA concentration, and favorable risk group. No published studies compared AS with immediate treatment with curative intent. Watchful waiting was generally less effective than treatment with curative intent; however, applicability to contemporary patients may be limited. Active surveillance and WW often could not be differentiated in the reviewed studies. Published randomized trials have assessed only WW and did not enroll patients diagnosed by PSA screening. Evidence is insufficient to assess whether AS is an appropriate option for men with localized prostate cancer. A standard definition of AS that clearly distinguishes it from WW is needed to clarify scientific discourse. Agency for Healthcare Research and Quality.

Integrated safety analysis: Short- and long-term safety profiles of etanercept in patients with psoriasis

Multiple trials demonstrate the tolerability and safety of etanercept. However, there are limited data on etanercept tolerability in large populations of patients with psoriasis or with extended therapy. We sought to determine whether there is an increased safety risk associated with higher etanercept doses or with extended exposure in patients with psoriasis. Integrated adverse event (AE) data from etanercept psoriasis trials were used to evaluate short-term (up to 12 weeks from controlled studies) and long-term (up to 144 weeks from uncontrolled extension studies) safety of etanercept (25 mg once weekly to 50 mg twice weekly). Long-term data were stratified by treatment regimens. Rates of noninfectious and infectious AE and standardized incidence ratios for malignancies were determined. In short-term analyses, rates of noninfectious and infectious AE and serious noninfectious and infectious AE were comparable between placebo and etanercept groups. In both short- and long-term analyses, there were no dose-related increases in these events. Cumulative event rates for serious infections were not significantly different across dose groups and over time. The standardized incidence ratios for malignancies excluding nonmelanoma skin cancers did not achieve statistical significance. There was no increase in overall malignancies with etanercept therapy compared with the psoriasis population. Lymphoma (n = 2 patients), demyelination (n = 2), congestive heart failure (n = 7), and opportunistic infection (n = 1) were rare. Study limitations include the rarity of some events and the resultant broad 95% confidence intervals. In this integrated analysis, etanercept was well tolerated, and there were no signs of dose-related or cumulative toxicity over time.

Patterns of biologic agent utilization among patients with rheumatoid arthritis: a retrospective cohort study.

BackgroundThe role of biologic therapies in the treatment of rheumatoid arthritis has expanded, but dosing patterns in the first versus subsequent lines of therapy have not been thoroughly explored.MethodsIn order to describe patterns of biologic agent utilization among patients with rheumatoid arthritis, health care claims data on use of abatacept, rituximab, or the anti-tumor necrosis factor (TNF) agents etanercept, adalimumab, and infliximab in first- or subsequent-line settings were used to form patient cohorts. Variables included: starting dose (first administration or fill), maintenance dose (third administration or fill), average dose, dose escalation, inter-infusion interval, and discontinuation (gap in therapy > 60 days or switch). Time to discontinuation was assessed with Kaplan-Meier curves and Cox proportional hazards models.ResultsOver 1 year, average (SD) doses of first-line etanercept (N = 1593; 45.4 [8.8] mg/week), adalimumab (N = 1040; 40.7 [10.4] mg/2 weeks), and abatacept (N = 360; 715.4 [214.5] mg/4 weeks) were similar to the starting and maintenance doses; the average infliximab dose (N = 538; 441.0 [209.2] mg/8 weeks) was greater than the starting and maintenance doses. Trends in the subsequent-line anti-TNF cohorts were similar. The percentages with a dose escalation or discontinuation were greater in the subsequent-line anti-TNF cohorts. The proportion with a dose escalation was greatest for the infliximab cohorts (61.2% first-line and 80.2% subsequent-line). The average period between abatacept infusions was 4.8 [1.4] weeks (4-week approved schedule); and 6.8 [2.6] months between rituximab courses (currently approved schedule is 6 months). Time to discontinuation was significantly shorter for subsequent-line than first-line anti-TNF therapy (median 9.7 vs. 12.5 mo; p < 0.001). The hazard ratio for discontinuing subsequent-line versus first-line anti-TNF therapy was 1.177 (p < 0.001).ConclusionsSubsequent-line anti-TNF therapy cohorts had higher rates of discontinuation, dose escalation, and shorter time to discontinuation than first-line anti-TNF cohorts.

Etanercept-Induced Encephalopathy in a 7-Year-Old Child

Adverse events were reported in various patients treated with etanercept, including infections (sepsis and tuberculosis), malignancies (e.g., lymphoma), demyelinating disorders, and autoimmune diseases. Only two adult patients with etanercept-related encephalopathy were previously reported. We describe a 7-year-old patient who developed encephalopathy immediately after his third dose of etanercept. To the best of our knowledge, ours is the first report of a pediatric patient with a diagnosis of systemic arthritis and who developed etanercept-related encephalopathy.

Long-term, continuous dosing of etanercept in patients with plaque psoriasis

Psoriasis, a chronic inflammatory skin disease, is characterized by periods of remission and relapse of lesions. Etanercept is approved for treatment of moderate-to-severe plaque psoriasis (25 mg twice weekly or 50 mg weekly). This review of three clinical trials evaluated the efficacy and safety of long-term, continuous (≥48 weeks) etanercept therapy in 1887 subjects with moderate-to-severe psoriasis (total exposure: 2458.0 subject-years). Efficacy end points across the three studies included: percent subjects achieving improvement of ≥75% from baseline in the Psoriasis Area and Severity Index; mean percentage improvement from baseline of Psoriasis Area and Severity Index; mean Physician’s Global Assessment psoriasis score; and Dermatology Life Quality Index total score (mean percentage improvement from baseline). Safety was also assessed. This article summarizes the sustained efficacy of long-term continuous etanercept therapy, which was generally consistent across the three trials. There were no new or...

Combined treatment with etanercept 50 mg once weekly and narrow-band ultraviolet B phototherapy in chronic plaque psoriasis

The combination of etanercept, a tumour necrosis factor α inhibitor, with narrow-band ultraviolet B (NB-UVB) phototherapy has recently been reported to be effective in moderate-to-severe plaque psoriasis, yielding better results than either monotherapy. To assess the efficacy and safety of this combined treatment using the lower approved etanercept dosage. In this single-arm open-label study patients received etanercept 50 mg once weekly combined with NB-UVB phototherapy three times weekly for 8 weeks, followed by etanercept alone until week 12. We evaluated the proportion of patients achieving 75%, 90% and 100% improvement of their initial PASI score (PASI75, PASI90, and PASI100, respectively). Patients were 19 men and 14 women, mean age 48.3 years ± 12.1 standard deviation (SD) and mean baseline Psoriasis Area and Severity Index (PASI) score 22.5 ± 7.5. On treatment weeks 4, 8, and 12, 24.2%, 66.7%, and 81.8% of patients achieved PASI75; 8.0%, 15.1%, and 57.6% reached PASI90, and 0%, 6.0%, and 24.2% attained PASI100, respectively. There were no severe side effects. Low-dosage etanercept combined with NB-UVB phototherapy is an effective, safe and economical approach to treat moderate-to-severe plaque psoriasis. Further studies are clearly required to assess its long-term efficacy and safety.

High-dose etanercept in ankylosing spondylitis: results of a 12-week randomized, double blind, controlled multicentre study (LOADET study)

Etanercept 50 mg a week is approved in the treatment of AS. Increasing the etanercept dose to 100 mg/week improves efficacy in cutaneous psoriasis, a clinical manifestation related to the spondylarthritis family, while maintaining its safety profile. The purpose of this study was to evaluate the efficacy and safety of etanercept 100 vs 50 mg/week in patients with AS. Adult patients with AS were randomized to receive etanercept 50 mg twice a week (biw), or etanercept 50 mg once a week (qw) for 12 weeks. The primary efficacy endpoint was Ankylosing Spondylitis Assessment Study (ASAS20) response at Week 12; secondary endpoints included ASAS40, ASAS50, ASAS70 and ASAS5/6 responses, partial remission and quality of life. Safety was assessed until 15 days after the last visit. A total of 108 patients were randomly selected and treated, 54 in each arm. At 12 weeks, ASAS20 response was achieved by 34 (71%) out of 48 patients of the etanercept 50 mg biw group and by 37 (76%) out of 49 patients of the etanercept 50 mg qw group (not statistically significant differences). Other efficacy variables improved significantly over time, but not between treatment groups. Fifty-six patients experienced at least one adverse event (generally, infections and infestations, gastrointestinal disorders and injection site reactions), most of them mild or moderate. High-dose (100 mg/week) etanercept in the treatment of AS for 12 weeks is as safe as the standard dose (50 mg/week). However, it does not significantly increase its efficacy. Trial Registration.

Baseline characteristics and patient reported outcome data of patients prescribed etanercept: web-based and telephone evaluation.

BackgroundThe anti-TNF inhibitor, etanercept is administered as a once or twice weekly subcutaneous injection for the treatment of rheumatoid arthritis, psoriasis, ankylosing spondylitis, psoriatic arthritis and juvenile idiopathic arthritis (JIA). Limited data from the patients' perspective are available on the use of biologics in the treatment of these chronic conditions and this evaluation was designed to collect data from patients who had been prescribed etanercept for the first time. This manuscript describes the self-reported baseline characteristics and health-related quality of life of patients prior to treatment. Follow-up data will be reported separately.MethodsPatients throughout the United Kingdom prescribed etanercept were invited to participate in an evaluation of their condition and treatment using a data collection tool consisting of a web-based system supplemented by telephone reporting (PROBE). Outcome measures reported at baseline included demographic data, the condition being treated, previous treatment with biologic agents and current and previous medications. Questions modified from standard, validated quality of life questionnaires such as EQ-5D were incorporated and patients made a global assessment of the severity of their own illness using the CGI-S scale.ResultsA total of 344 patients/carers/parents participated in the evaluation at baseline, 290 (84%) by online questionnaire and 54 (16%) by telephone. Overall, the study population had a mean age of 53 years, was predominantly female (62%) and 20% had been previously treated with a biologic agent. A total of 191 (56%) patients were receiving treatment with etanercept for rheumatoid arthritis, 44 (13%) for psoriatic arthritis, 43 (13%) for ankylosing spondylitis, 35 (10%) for psoriasis, 9 (3%) for known juvenile idiopathic arthritis (JIA) and 22 (6%) for another condition/patient unsure/missing response. All patients were prescribed the 50 mg weekly dose of etanercept except for 1 patient with JIA (40 mg) dose and 2 patients with psoriasis (100 mg). Thirty-eight percent of patients with rheumatoid arthritis were not receiving treatment with methotrexate.ConclusionsThe baseline characteristics and health-related quality of life of first time users of etanercept can be adequately described using self-reported patient data collected using an online questionnaire with a telephone option (PROBE).
