Abstract: Osteoarthritis (OA) is the most common form of arthritis and one of the leading causes of disability worldwide. The incidence of OA increases with age, and as longevity increases, it will cause a significant socioeconomic burden. No disease-modifying therapy is available for OA. Recent research has highlighted the role of inflammation in the progression of OA. Interleukin-1 appears to have a significant role in disease progression. Since the interleukin-1 receptor antagonist (IL-1Ra) anakinra has been used successfully in the treatment of the inflammation and bone destruction of rheumatoid arthritis, some have suggested that it may be able to retard the disease progression of OA. This article reviews the data on the use of anakinra in OA treatment.

Abstract: The performance of clinical trials can be very rewarding for the practicing or academic clinical rheumatologist. There are at least 50 new compounds - small molecules and biologics - in development for rheumatic diseases such as rheumatoid arthritis, osteoarthritis, systemic lupus erythematosus, ankylosing spondylitis, psoriatic arthritis, scleroderma, gout and fibromyalgia. Clinical trials are important to try to determine the appropriate use of these compounds, as well as to answer questions about their safety. To carry out clinical trials effectively, the physician-investigator must be aware of, and adhere to, the regulatory requirements. The purpose of this article is to review these requirements in depth, as well as to discuss the infrastructure required to establish a successful clinical trial unit.

Abstract: Rheumatoid arthritis (RA), ankylosing spondylitis (AS) and psoriatic arthritis (PsA) are commonly thought of as inflammatory diseases that affect younger individuals. Although the initial presentation of these diseases is commonly in a patient's twenties or thirties, they usually persist for the duration of the patient's life. In addition, up to one-third of patients with RA have disease onset after 60 years of age. Older patients with any of these three diseases are more likely to have more severe disease with significant functional decline. They are also more likely to have co-morbid diseases and use concomitant medications than patients who are younger. In patients with RA, AS or PsA, the introduction of anti-tumour necrosis factor (TNF)-alpha therapies such as etanercept, infliximab and adalimumab has had a significant impact in ameliorating the signs and symptoms of disease, improving patient function and inhibiting radiographic progression. Anti-TNFalpha therapies now have well recognised safety profiles that have been demonstrated in the usual clinical trial populations for these diseases, but such populations under-represent patients > or =65 years of age. This review explores the information currently available regarding patients aged > or =65 years treated with anti-TNFalpha therapies for RA, AS or PsA, focusing on etanercept in RA because of a lack of data for other therapies and conditions. The analyses conducted show that there is similar efficacy in the treatment of RA in patients <65 years old and those > or =65 years of age. Although there are some differences in the adverse events noted in these two age groups, it appears as though treatment of patients > or =65 years of age, compared with age-matched controls, is not dissimilar to treatment of patients <65 years of age compared with their age-matched controls. Only by understanding the risks and benefits of therapy in the older age group can a true risk : benefit profile for etanercept, and ultimately other anti-TNFalpha therapies, be determined by the practising physician and the patient.

Abstract: Tacrolimus is an immunosuppressive drug that has been used widely in organ transplantation and topically for atopic dermatitis. Tacrolimus exerts its immunosuppressive effects by the inhibition of calcineurin, leading to interference with T-cell activation. As T-cell activation plays a major role in the pathogenesis of rheumatoid arthritis, there has been an interest in the use of tacrolimus for the treatment of rheumatoid arthritis. The pharmacological properties of tacrolimus have the potential of suppressing the production of inflammatory cytokines, improvement of joint inflammation, improvement of bone and cartilage destruction, improvement of functional status and relief from arthritic pain. This article reviews the pharmacodynamics, pharmacokinetics, clinical efficacy, safety and role of tacrolimus in the treatment of rheumatoid arthritis.

Abstract: Anakinra (Amgen, Inc.) is a specific receptor antagonist of IL-1 that differs from naturally occurring IL-1 receptor antagonist by the presence of a methionine group. Anakinra has been shown to be of benefit in patients with active rheumatoid arthritis, either when given alone or in combination with methotrexate, as assessed by improvement in clinical signs and symptoms, decreased radiographic progression and improvement in patient function, pain and fatigue, although it appears to be effective in fewer patients than anti-TNF agents. It has a favourable safety profile as demonstrated in clinical trials. The physician and patient must be cognizant of serious infectious episodes. Many of the rare side effects seen with TNF blockers, such as tuberculosis, other opportunistic infections, worsening of congestive heart failure and the development of demyelinating disease, have not been seen in patients treated with anakinra. Anakinra should not be given in combination with anti-TNF agents.

Abstract: Tumor necrosis factor (TNF) antagonists are biologic response modifiers that have significantly improved the outcomes in patients with rheumatoid arthritis (RA). At this report, safety data were collected on approximately 271,000 patients administered infliximab (as of February 2002), 121,000 patients administered etanercept (as of December 2001), and on 2400 patients who received adalimumab in trials in connection with the regulatory approval process (approval granted December 2002 in the US and September 2003 in European Union). Infliximab and etanercept have predictable and manageable safety profiles, and preliminary data suggest that the profile of adalimumab is comparable. Safety issues involving the anti-TNF agents as a class include the risk of injection-site reactions or infusion-related reactions, infection (for example, serious, opportunistic, or tubercular), malignancy, autoimmunity, and demyelinating and neurologic disorders. Injection-site and infusion-related reactions are most often easily managed and rarely lead to discontinuation of therapy. Infections can be minimized or prevented by screening and careful monitoring and follow-up; most infections respond to appropriate medical treatment. More studies are needed to evaluate the occurrence of malignancies in patients with RA to determine the potential risk posed by therapy. Antibody formation can follow the administration of any biologic agent. Although demyelinating disease has been reported with anti-TNF agents, it is not clear whether a causal relationship exists. Overall, the anti-TNF agents are well tolerated and have demonstrated a favorable benefit-to-risk profile in patients with RA.

Abstract: Tumor necrosis factor (TNF) antagonists have dramatically improved the outcomes of rheumatoid arthritis (RA). Three agents currently available in the USA--infliximab, etanercept, and adalimumab--have been designed to modify the biologic effects of TNF. Infliximab and adalimumab are monoclonal antibodies, and etanercept is a soluble protein. The pharmacokinetic and pharmacodynamic properties of each differs significantly from those of the others. All three agents are effective and safe, and can improve the quality of life in patients with RA. Although no direct comparisons are available, clinical trials provide evidence that can be used to evaluate the comparative efficacy of these agents. Infliximab, in combination with methotrexate, has been shown to relieve the signs and symptoms of RA, decrease total joint score progression, prevent joint erosions and joint-space narrowing, and improve physical function for up to 2 years. Etanercept has been shown to relieve the signs and symptoms of RA, decrease total joint score progression, and slow the rate of joint destruction, and might improve physical function. Etanercept is approved with and without methotrexate for patients who have demonstrated an incomplete response to therapy with methotrexate and other disease-modifying anti-rheumatic drugs (DMARDs), as well as for first-line therapy in early RA, psoriatic arthritis, and juvenile RA. Adalimumab relieves the signs and symptoms of RA with and without methotrexate and other DMARDs, decreases total joint score progression, prevents joint erosions and joint-space narrowing in combination with methotrexate, and might improve physical function. When selecting a TNF antagonist, rheumatologists should weigh evidence and experience with specific agents before a decision is made for use in therapy.

Abstract: The definition of disease-modifying antirheumatic drugs (DMARDs) has changed dramatically over the last decade. Current expectations of efficacy now include amelioration of signs and symptoms of disease activity as well as slowing, if not complete cessation, of disease progression as evidenced by Xray progression and significant improvement of patient function. Rheumatologists assess the safety profile of these agents more critically in an attempt to increase the risk:benefit profile. Traditional agents, such as methotrexate (MTX), sulfasalazine and leflunomide have provided patients with substantial relief of symptoms and some decrease of X-ray progression but have been hampered by the frequent occurrence of significant adverse events (AEs) and inability to maintain benefit for a prolonged period of time. With the increased understanding of the basic mechanism of the disease process, there has been the introduction of four biological disease-modifying agents introduced into clinical practice which have substantially increased the risk:benefit ratio for patients with various rheumatic diseases.

Abstract: Meloxicam (Mobic trade mark, Boehringer Ingelheim) is a relatively new oral non-steroidal anti-inflammatory drug (NSAID) approved for the treatment of osteoarthritis in the US. It has also been evaluated for the treatment of rheumatoid arthritis, ankylosing spondylitis and acute 'rheumatic' pain. Meloxicam has been shown to be COX-2 preferential, particularly at its lowest therapeutic dose, and is anti-inflammatory by inhibiting prostanoid synthesis in inflammatory cells. Since it is COX-2 preferential, it would be expected to have less gastrointestinal toxicity than non-selective NSAIDs. In clinical trials of meloxicam in osteoarthritis, it was found to be as effective as piroxicam, diclofenac and naproxen with less clinical gastrointestinal symptoms and less perforations, obstructions and bleeds by meta-analysis. Adverse events, including peripheral oedema and hypertension, occurred at a similar rate as with traditional NSAIDs.

Abstract: The traditional approach to the treatment of rheumatoid arthritis (RA) has been the use of nonsteroidal anti-inflammatory drugs usually in combination with a disease-modifying antirheumatic drug (DMARD) such as hydroxychloroquine, gold, sulfasalazine, methotrexate, leflunomide or cyclosporin. Each of these DMARDs has its own distinct toxicities but has also been shown to be effective in reducing signs and symptoms of disease and to some extent, reduce radiological progression. Within the past 10 years, the combination of several traditional DMARDs has been shown to have increased efficacy over monotherapy without a significant increase in toxicity in a majority of studies. Recently, the US Food and Drug Administration has approved infliximab, a chimeric monoclonal antibody to tumour necrosis factor (TNF)-alpha in combination with methotrexate, for the treatment of signs and symptoms of RA, delay of radiological progression of disease and improvement of physical function while anakinra, an interleukin-1 receptor antagonist, has been approved for the treatment of the signs and symptoms of RA either as monotherapy or in combination with methotrexate. Etanercept is the first biological response modifier approved for use in RA in the US. Double-blind, randomised controlled studies have shown etanercept to be effective therapy in patients with RA who have had inadequate response to DMARDs, in combination with methotrexate, and as early monotherapy. Similar results were seen in juvenile and psoriatic arthritis in DMARD nonresponders. Open-label studies have shown efficacy in adult Still's disease, ankylosing spondylitis, progressive systemic sclerosis, Wegener's granulomatosis and chronic uveitis. Safety issues are a concern because of the ubiquitous role of TNF. To date the only consistent adverse event seen with etanercept has been injection site reactions. Infections occur at the same rate and with the same frequency as the placebo population. There should be caution, however, with using etanercept in patients with a serious infection, or recurrent infections or patients with untreated or latent tuberculosis. As of yet there has not been seen an increase of malignancies. Rare neurological and haematological events have been noted. Etanercept has been a significant addition to the armamentarium of medications for the treatment of RA, juvenile and psoriatic arthritis. Preliminary data show that it may be well tolerated and effective in other rheumatic diseases in which there is over production of TNFalpha.

Abstract: OBJECTIVE: To determine the safety and efficacy of additional courses of rituximab in patients with rheumatoid arthritis (RA). METHODS: An open-label extension analysis of RA patients previously treated with rituximab was conducted. Patients who had participated in any of 3 double-blind trials were eligible for additional courses (2 infusions of 1,000 mg given 2 weeks apart) if they exhibited a swollen joint count and tender joint count of > or =8 with > or =16 weeks elapsing after the previous course. Safety was assessed in patients receiving all or a portion of a rituximab course. Efficacy was assessed 24 weeks after each course, using the American College of Rheumatology 20% criteria for improvement (ACR20), ACR50, ACR70, European League Against Rheumatism (EULAR) response criteria, Disease Activity Score in 28 joints, the disability index of the Health Assessment Questionnaire, and Short Form 36 scores, stratified according to prior tumor necrosis factor (TNF) inhibitor exposure. RESULTS: A total of 1,039 patients received > or =1 course of rituximab. Of these, 570 received 2 courses, 191 received 3 courses, and 40 received 4 courses, for a total of 1,669 patient-years. Irrespective of prior TNF inhibitor exposure, ACR20 responses were comparable at week 24 after course 1 and at week 24 after course 2 (65% versus 72%), as were ACR50 and ACR70 responses. EULAR moderate/good responses were also comparable in course 2 relative to course 1 (88% versus 79%), with EULAR remission occurring in a 2-fold higher proportion of patients after course 2 than after course 1 (13% versus 6%). The most common adverse events, which were mild-to-moderate acute infusion-related events, decreased with each course. The serious infection rate after course 1 (5.1 per 100 patient-years) remained stable through additional courses. The proportion of patients with circulating IgM and IgG levels below the lower limit of normal (LLN) increased with subsequent courses; however, serious infection rates in these patients (5.6 per 100 patient-years in patients with low IgM levels and 4.8 per 100 patient-years in patients with low IgG levels were comparable with those in patients with immunoglobulin levels above the LLN (4.7 per 100 patient-years). Patients with human antichimeric antibody (9.2%) did not exhibit decreasing efficacy or present additional safety concerns. CONCLUSION: These findings indicate that patients treated with repeated courses of rituximab have sustained clinical responses with no new adverse events.

Abstract: OBJECTIVE: To examine the efficacy and safety of different rituximab doses plus methotrexate (MTX), with or without glucocorticoids, in patients with active rheumatoid arthritis (RA) resistant to disease-modifying antirheumatic drugs (DMARDs), including biologic agents. METHODS: A total of 465 patients were randomized into 9 treatment groups: 3 rituximab groups (placebo [n = 149], 500 mg [n = 124], or 1,000 mg [n = 192] on days 1 and 15) each also taking either placebo glucocorticoids, intravenous methylprednisolone premedication, or intravenous methylprednisolone premedication plus oral prednisone for 2 weeks. All patients received MTX (10-25 mg/week); no other DMARDs were permitted. RESULTS: Significantly more patients who received 2 500-mg or 2 1,000-mg infusions of rituximab met the American College of Rheumatology 20% improvement criteria (achieved an ACR20 response) at week 24 (55% and 54%, respectively) compared with placebo (28%; P < 0.0001). ACR50 responses were achieved by 33%, 34%, and 13% of patients, respectively (P < 0.001), and ACR70 responses were achieved by 13%, 20%, and 5% of patients (P < 0.05). Changes in the Disease Activity Score in 28 joints (-1.79, -2.05, -0.67; P < 0.0001) and moderate to good responses on the European League Against Rheumatism criteria (P < 0.0001) reflected the ACR criteria responses. Glucocorticoids did not contribute significantly to the primary efficacy end point, ACR20 response at 24 weeks. Intravenous glucocorticoid premedication reduced the frequency and intensity of first infusion-associated events; oral glucocorticoids conferred no additional safety benefit. Rituximab was well tolerated; the type and severity of infections was similar to those for placebo. CONCLUSION: Both rituximab doses were effective and well tolerated when added to MTX therapy in patients with active RA. The primary end point (ACR20 response) was independent of glucocorticoids, although intravenous glucocorticoid premedication improved tolerability during the first rituximab infusion.

Abstract: OBJECTIVE: In a phase 2 study, to assess the efficacy and safety of pegsunercept, a soluble tumor necrosis factor receptor type I, for the treatment of rheumatoid arthritis (RA). METHODS: Patients were randomized to receive weekly subcutaneous injections of placebo (n = 61) or active drug [400 microg/kg (n = 67) or 800 microg/kg (n = 66)] for 12 weeks. The primary efficacy endpoint was American College of Rheumatology 20% response (ACR20) at Week 12. Secondary efficacy measures included ACR50 and ACR70 responses, and changes in individual ACR components at Week 12. Safety assessments included summaries of adverse events including infectious episodes. RESULTS: Treatment with pegsunercept resulted in a significantly higher ACR20 response at Week 12 in the 800 microg/kg group (45%) compared with the placebo group (26%; p = 0.020). The treatment effect of pegsunercept (both doses) over the study period showed statistically significant improvement for most ACR components and health related quality of life, with the 800 microg/kg group showing greater clinical improvements in efficacy measures. The overall incidence of adverse events and infectious episodes was similar among the treatment and placebo groups. CONCLUSION: In this 12 week dose-finding study of 194 patients, weekly subcutaneous dosing with pegsunercept showed beneficial effects in improving the signs and symptoms of RA. It appeared to be safe and well tolerated in this small number of patients. Significant clinical improvements were seen in patients in the 800 microg/kg group; however, this dose may be suboptimal, and further evaluation of this product with higher doses or a more frequent dosing regimen is warranted.

Abstract: OBJECTIVE: To determine in a placebo-controlled, double-blind trial the safety profile of daily anakinra (Kineret) use in patients with active rheumatoid arthritis (RA) and concurrent comorbid conditions. METHODS: In 169 centers in 9 countries, 1,414 patients with active RA were randomly assigned to receive either anakinra (100 mg) or placebo treatment (4:1 anakinra-to-placebo allocation ratio), with study drug administered by daily subcutaneous injection for 6 months. The current post hoc analysis assessed baseline comorbid conditions, and patients were considered at high risk for the occurrence of adverse events if they had a history of at least one of the following: cardiovascular event, pulmonary event, central nervous system-related event, infection, diabetes, malignancy, or renal impairment. Within each treatment group (anakinra or placebo), incidence rates were summarized for serious adverse events, infectious events, and serious infectious events in high-risk patients and compared with these incidence rates in patients without comorbid conditions. RESULTS: The majority of patients in the trial had one or more comorbid conditions. In these high-risk patients, there were no differences in the incidence of serious adverse events or infectious events between treatment groups. The incidence of serious infectious events with anakinra use was similar between high-risk patients (2.5%) and the entire study population (2.1%) and was not attributable to any single comorbidity. CONCLUSION: Results of the analysis of adverse events in patients with active RA and coexisting comorbidities suggest that the favorable safety profile of anakinra is maintained in a high-risk patient population.

Abstract: OBJECTIVE: To examine the safety of anakinra when added to a background of standard rheumatoid arthritis (RA) medications in patients with RA with active disease. METHODS: This analysis further evaluates data from the first 6 months of a blinded, placebo controlled safety trial that had a subsequent 30 month, open label portion (not reported here). Patients with RA with a wide range of comorbid conditions, disease activity, and background medications were randomly assigned in a 4:1 allocation ratio to treatment with anakinra 100 mg or placebo administered daily by injection. Safety was assessed by comparing adverse event profiles between anakinra and placebo patients according to concomitant medications received. RESULTS: Anakinra patients (n = 1116) showed no difference in the incidence of upper respiratory infections or overall serious adverse events compared with placebo patients (n = 283). The anakinra group had more injection site reactions (72.6% vs 32.9% in placebo) and a small increase in serious infections (2.1% vs 0.4% in placebo). Anakinra's safety profile did not differ in patients receiving antihypertensive, antidiabetic, or statin drugs. CONCLUSION: This study indicates that anakinra has a good safety profile in patients typically seen in a rheumatology practice who are considered candidates for therapy with agents that are immunomodulatory and disease modifying. Except for injection site reactions and a nonstatistically although potentially clinically significant increase in serious infections in the anakinra versus the placebo groups, the addition of anakinra to a stable background regimen of RA medications introduced no other important safety risk in patients with RA.

Abstract: OBJECTIVE: To determine the safety and efficacy of etanercept in a multicenter, randomized, placebo-controlled, double-blind trial of adults with moderate to severe active ankylosing spondylitis (AS). METHODS: Patients (n = 277) were treated with either etanercept 25 mg (n = 138) or placebo (n = 139) subcutaneously twice weekly for 24 weeks. The primary outcome measures were the percentages of patients achieving the Assessments in Ankylosing Spondylitis 20% response (ASAS20) at weeks 12 and 24. Other outcome measures included the percentage of patients achieving higher ASAS responses, and the safety of etanercept in patients with AS. All outcome measures were assessed at 2, 4, 8, 12, and 24 weeks. RESULTS: Treatment with etanercept resulted in dramatic improvement. The ASAS20 was achieved by 59% of patients in the etanercept group and by 28% of patients in the placebo group (P < 0.0001) at week 12, and by 57% and 22% of patients, respectively, at week 24 (P < 0.0001). All individual ASAS components, acute-phase reactant levels, and spinal mobility measures were also significantly improved. The safety profile of etanercept was similar to that reported in studies of patients with rheumatoid arthritis or psoriatic arthritis. The only adverse events that occurred significantly more often in the etanercept group were injection-site reactions, accidental injuries, and upper respiratory tract infections. CONCLUSION: Etanercept is a highly effective and well tolerated treatment in patients with active AS.

Abstract: OBJECTIVE: This Phase III, placebo and active controlled, multicenter trial evaluated the efficacy and safety of meloxicam 7.5, 15, and 22.5 mg daily for the treatment of rheumatoid arthritis (RA). METHODS: A 12 week, randomized, double blind, double dummy, parallel group trial compared daily oral meloxicam 7.5, 15, and 22.5 mg to placebo (negative control) and diclofenac 75 mg BID (positive control). A total of 894 patients (18 years of age with confirmed RA who flared following an NSAID-free period) were randomized to be treated. Baseline scores for all endpoints were similar among the treatment groups. Patient assessments were at 0, 2, 4, 8, and 12 weeks or early termination. RESULTS: All treatment groups demonstrated significant improvement from baseline (p < 0.001). Meloxicam 7.5 and 22.5 mg was significantly superior to placebo in all 5 primary efficacy endpoints (swollen joint count, tender joint count, patient pain, patient and physician global; all p < 0.05). Diclofenac 150 mg was superior to placebo for 4 of 5 primary efficacy measures (all but swollen joint count; p < 0.05) and meloxicam 15 mg was superior for 3 of 5 primary endpoints (patient pain and patient and physician global). AUC of patient global, patient pain, and modified Health Assessment Questionnaire demonstrated dose-response (p < 0.04), while AUC ACR20 showed a qualitative trend in the same direction. The rate of gastrointestinal (GI) events during the 12 week trial for all doses of meloxicam and diclofenac did not differ significantly from placebo (23.2-32.0%). GI withdrawals were comparable and not significantly different across all treatment groups (4.3-5.7%). CONCLUSION: This trial demonstrated a dose response relationship for meloxicam 7.5, 15, and 22.5 mg using AUC measurement of response for the treatment of RA. All 3 doses of meloxicam. and positive control, were effective in the treatment of RA. The overall incidence rate of GI events did not differ significantly from placebo in either the meloxicam treatment groups or the positive control.

Abstract: CONTEXT: Leflunomide is a reversible inhibitor of de novo pyrimidine synthesis shown to be effective in a phase 2 trial in 402 patients with active rheumatoid arthritis (RA). OBJECTIVE: To compare the efficacy and safety of leflunomide treatment with placebo and methotrexate treatment in patients with active RA. DESIGN: Randomized, double-blind, placebo, and active-controlled 12-month study. SETTING: Forty-seven university and private rheumatology practices in the United States and Canada. PATIENTS: Diagnosis of RA by the American College of Rheumatology (ACR) criteria for duration of 6 months or longer and no previous methotrexate treatment. INTERVENTION: Leflunomide treatment (20 mg/d), placebo, or methotrexate treatment (7.5-15 mg/wk). MAIN OUTCOME MEASURES: American College of Rheumatology success rate (completed 52 weeks of treatment and met the ACR > or = 20% response criteria), disease progression as assessed by x-ray films, and improvement in function and health-related quality of life using the intent-to-treat population. RESULTS: The 482 patients studied were predominantly women (mean age, 54 years; mean disease duration, 6.7 years) for whom a mean of 0.8 disease-modifying antirheumatic drugs had failed. The ACR response and success rates for patients receiving leflunomide treatment (52% and 41%, respectively) and methotrexate treatment (46% and 35%, respectively) were significantly higher than those for patients receiving placebo (26% and 19%, respectively) (P<.001), and they were statistically equivalent, with mean time to initial response at 8.4 weeks for patients receiving leflunomide vs 9.5 weeks for patients receiving methotrexate therapy. X-ray analyses demonstrated less disease progression with leflunomide (P=.001) and methotrexate (P = .02) therapy than with placebo. Leflunomide and methotrexate treatment improved measures of physical function and health-related quality of life significantly more than placebo (P<.001 and P<.05, respectively). Common adverse events for patients receiving leflunomide treatment included gastrointestinal complaints, skin rash, and reversible alopecia. Asymptomatic transaminase elevations resulted in treatment discontinuations for 7.1% of patients receiving leflunomide therapy, 1.7% of patients receiving placebo, and 3.3% of patients receiving methotrexate therapy. CONCLUSIONS: Clinical responses following administration of leflunomide, a new therapeutic agent for the treatment of RA, were statistically superior to those with placebo and equivalent to those with methotrexate treatment. Both active treatments improved signs and symptoms of active RA, delayed disease progression as demonstrated by x-ray films, and improved function and health-related quality of life.

Abstract: Nonsteroidal anti-inflammatory drugs. (NSAIDs) inhibit both cyclooxygenase (COX)-1 and COX-2 isoenzymes and are effective in the treatment of inflammatory disorders. This 8-week, double-masked, placebo-controlled trial was undertaken to assess the safety profile, tolerability, and effective dose range of once-daily rofecoxib, a COX-2-specific inhibitor, in the treatment of rheumatoid arthritis (RA). After a 3- to 15-day washout of prior NSAID therapy, 658 patients were randomly allocated to receive placebo or rofecoxib 5 mg, 25 mg, or 50 mg once daily. Safety profile, tolerability, and efficacy were evaluated after 2, 4, and 8 weeks of therapy. Six hundred fifty-eight patients (168, 158, 171, and 161 in the placebo and 5-mg, 25-mg, and 50-mg rofecoxib groups, respectively) were enrolled at 79 clinical centers in the United States. Mean age was 55 years, mean duration of RA was 10 years, and 506 (77%) of the 658 patients were female. All groups had similar baseline demographic characteristics. Patients taking rofecoxib 25 and 50 mg showed significant clinical improvement compared with those taking placebo; 43.9% in the rofecoxib 25-mg group and 49.7% in the rofecoxib 50-mg group completed the treatment period and achieved an American College of Rheumatology 20 response (P = 0.025 and 0.001 vs. placebo, respectively). The 5-mg dose of rofecoxib did not differ significantly from placebo. Patients in the rofecoxib 25- and 50-mg groups showed significant improvement in key individual efficacy measurements, including patient global assessment of pain, patient and investigator global assessment of disease activity, and Stanford Health Assessment Questionnaire Disability Index (P<0.05 vs placebo). Compared with placebo, significantly fewer patients in the 25-mg and 50-mg rofecoxib groups discontinued therapy because of lack of efficacy (P = 0.02 and P = 0.032, respectively). Our results show that rofecoxib 25 and 50 mg once daily was effective and generally well-tolerated in patients with RA.

Abstract: OBJECTIVE: To evaluate the efficacy and safety of the Prosorba column as a treatment for rheumatoid arthritis (RA) in patients with active and treatment-resistant (refractory) disease. METHODS: A sham-controlled, randomized, double-blind, multicenter trial of Prosorba versus sham apheresis was performed in patients with RA who had failed to respond to treatment with methotrexate or at least 2 other second-line drugs. Patients received 12 weekly treatments with Prosorba or sham apheresis, with efficacy evaluated 7-8 weeks after treatment ended. Patients were characterized as responders if they experienced improvement according to the American College of Rheumatology (ACR) response criteria at the efficacy time point. A data safety monitoring board (DSMB) evaluated interim analyses for the possibility of early completion of the trial. RESULTS: Patients in the trial had RA for an average of 15.5 years (range 1.7-50.6) and had failed an average of 4.2 second-line drug treatments prior to entry. After the completion of treatment of 91 randomized patients, the DSMB stopped the trial early due to successful outcomes. Of the 47 patients in the Prosorba arm, 31.9% experienced ACR-defined improvement versus 11.4% of the 44 patients in the sham-treated arm (P = 0.019 after adjustment for interim analysis). When results from 8 additional patients, who had completed blinded treatments at the time of DSMB action, were added to the analysis (n = 99), results were unchanged. The most common adverse events were a short-term flare in joint pain and swelling following treatment, a side effect that occurred in most subjects at least once in both treatment arms. Other side effects, although common, occurred equally as frequently in both treatment groups. CONCLUSION: Apheresis with the Prosorba column is an efficacious treatment for RA in patients with active disease who have failed other treatments.

Abstract: BACKGROUND: Tumour necrosis factor alpha (TNFalpha) is a proinflammatory cytokine involved in the pathogenesis of rheumatoid arthritis (RA). Treatment with TNFalpha inhibitors reduces disease activity and improves outcomes for patients with RA. This study evaluated the efficacy and safety of certolizumab pegol 400 mg, a novel, poly-(ethylene glycol) (PEG)ylated, Fc-free TNFalpha inhibitor, as monotherapy in patients with active RA. METHODS: In this 24-week, multicentre, randomised, double-blind, placebo-controlled study, 220 patients previously failing > or =1 disease-modifying antirheumatic drug (DMARD) were randomised 1:1 to receive subcutaneous certolizumab pegol 400 mg (n = 111) or placebo (n = 109) every 4 weeks. The primary endpoint was 20% improvement according to the American College of Rheumatology criteria (ACR20) at week 24. Secondary endpoints included ACR50/70 response, ACR component scores, 28-joint Disease Activity Score Erythrocyte Sedimentation Rate 3 (DAS28(ESR)3), patient-reported outcomes (including physical function, health-related quality of life (HRQoL), pain and fatigue) and safety. RESULTS: At week 24, the ACR20 response rates were 45.5% for certolizumab pegol 400 mg every 4 weeks vs 9.3% for placebo (p<0.001). Differences for certolizumab pegol vs placebo in the ACR20 response were statistically significant as early as week 1 through to week 24 (p<0.001). Significant improvements in ACR50, ACR components, DAS28(ESR)3 and all patient-reported outcomes were also observed early with certolizumab pegol and were sustained throughout the study. Most adverse events were mild or moderate and no deaths or cases of tuberculosis were reported. CONCLUSIONS: Treatment with certolizumab pegol 400 mg monotherapy every 4 weeks effectively reduced the signs and symptoms of active RA in patients previously failing > or =1 DMARD compared with placebo, and demonstrated an acceptable safety profile. Trial registration number: NCT00548834.

Abstract: OBJECTIVES: To determine the long term safety profile of the tumour necrosis factor (TNF) antagonist etanercept in subjects with rheumatoid arthritis (RA), psoriatic arthritis (PsA), or ankylosing spondylitis (AS) aged > or =65 years in comparison with subjects aged <65 years. METHODS: Safety data from an integrated database of 4322 subjects enrolled in 18 RA trials, 2 PsA trials, and 2 AS trials were analysed. Safety end points included subject incidence of all adverse events (AE), serious adverse events (SAE), infectious events (IE), medically important infections (MII), and deaths. Events of particular interest in subjects treated with TNF modulating biological treatments, including demyelinating diseases, tuberculosis, lymphomas, and cardiovascular diseases, were also evaluated. RESULTS: The incidence of AE, SAE, IE, MII, and malignancies was not significantly raised in elderly subjects in comparison with subjects aged <65 years. No cases of tuberculosis were reported in the trials. Demyelinating diseases were seen only in subjects aged <65 years. The incidence and types of death in the elderly subjects were consistent with the expected rates for subjects of comparable age. CONCLUSIONS: Etanercept is a generally safe and well tolerated biological agent for treatment of rheumatological diseases in the elderly, and the risk of AE in these studies was no greater in subjects aged > or =65 years than in younger subjects.
