Effectiveness and safety of intravenous golimumab with and without concomitant methotrexate in patients with rheumatoid arthritis in the prospective, noninterventional AWARE study.

BACKGROUND: Biologic therapies are often prescribed for patients with rheumatoid arthritis (RA) who have inadequate responses to or are intolerant of methotrexate (MTX) and patients with poor prognostic indicators. This post hoc analysis evaluated effectiveness and safety of intravenous golimumab + MTX vs golimumab without MTX in RA patients. METHODS: AWARE, a real-world, prospective and pragmatic, Phase 4 study, compared effectiveness and safety of golimumab and infliximab in biologic-naïve and biologic-experienced patients. All treatment decisions were at the discretion of the treating rheumatologist. Effectiveness was evaluated by mean change in CDAI scores at Months 6 and 12. Safety was monitored through approximately 1 year. RESULTS: Among 685 golimumab-treated patients, 420 (61%) received concomitant MTX during the study and 265 (39%) did not receive MTX after enrollment; 63% and 72%, respectively, discontinued the study. Relative to golimumab without MTX, golimumab + MTX patients had shorter mean disease duration (8.7 vs 10.0 years) and a lower proportion received prior biologics (60% vs 72%); mean ± standard deviation (SD) baseline CDAI scores were similar (30.8 ± 15.1 and 32.6 ± 15.4). Mean ± SD changes from baseline in CDAI scores at Months 6 and 12, respectively, were similar with golimumab + MTX (- 10.2 ± 14.2 and - 10.8 ± 13.8) and golimumab without MTX (- 9.6 ± 12.9 and - 9.9 ± 13.1). The incidence of adverse events/100 patient-years (PY) (95% confidence interval [CI]) was 155.6 (145.6, 166.1) for golimumab + MTX and 191.2 (176.2, 207.1) for golimumab without MTX; infections were the most common type. The incidence of infusion reactions/100PY (95% CI) was 2.1 (1.1, 3.6) for golimumab + MTX versus 5.1 (2.9, 8.3) for golimumab without MTX; none were considered serious. For golimumab + MTX versus golimumab without MTX, rates/100PY (95% CI) of serious infections, opportunistic infections, and malignancies were 2.6 (1.5, 4.3) versus 7.0 (4.4, 10.6), 0.9 (0.3, 2.0) versus 2.6 (1.1, 5.0), and 3.0 (1.7, 4.7) versus 1.0 (0.2, 2.8), respectively. CONCLUSIONS: Mean change in CDAI score in the  golimumab without MTX group was generally similar to that of the golimumab + MTX group through 1 year, regardless of prior biologic therapy. Adverse events were consistent with the known IV golimumab safety profile. These results provide real world evidential data that may assist healthcare providers and patients with RA in making informed treatment decisions.

A Pulsed Electrical Joint Stimulator for the Treatment of Osteoarthritis of the Hand and Wrist.

The hand is commonly affected by osteoarthritis (OA). The development and progression of OA are believed to involve inflammation, even in the early stages of the disease. Inflammatory and proinflammatory cytokines have also been shown to be elevated in the flexor tenosynovium of idiopathic carpal tunnel syndrome (CTS). A large percentage of patients with hand OA also have a concomitant CTS. This study evaluated the results of a pulsed electrical joint stimulator in patients who had hand OA with or without CTS. Pain, tenderness, and swelling; grip strength and pinch force; and Patient and Physician Global Assessment and Disabilities of the Arm, Shoulder and Hand (DASH) results were evaluated. The primary efficacy outcome was pain due to OA in the study hand in the past 48 hours. Secondary outcomes consisted of OA pain in the study thumb in the past 48 hours, grip strength, pinch force, and Patient and Physician Global Assessment and DASH results. All 7 outcome parameters improved in OA patients. On physical examination, individual finger and wrist joints had also improved regarding pain, swelling, and tenderness. In the subset of patients with CTS, CTS pain, paresthesia, weakness, and all CTS symptoms had significantly improved. Patient and Physician Global Assessment and DASH results and pinch force were also significantly improved. This pulsed electrical joint stimulator is effective in providing clinically relevant and statistically significant reductions in the signs and symptoms of OA of the hand and CTS. It could be a useful modality for the treatment of patients who have one of these conditions or both. [Orthopedics. 2018; 41(4):e550-e556.].

Vaccine responses in patients with rheumatoid arthritis treated with certolizumab pegol: results from a single-blind randomized phase IV trial.

OBJECTIVE: To evaluate the humoral immune response to pneumococcal and influenza vaccination in adults with rheumatoid arthritis (RA) receiving certolizumab pegol (CZP). METHODS: In this 6-week, single-blind, placebo-controlled trial with optional 6-month open-label extension (NCT00993668), patients were stratified by concomitant methotrexate (MTX) use and randomized to receive CZP 400 mg (loading dose; according to CZP label) or placebo at weeks 0, 2, and 4. Pneumococcal (polysaccharide 23) and influenza vaccines were administered at Week 2. Satisfactory humoral immune response, defined as ≥2-fold titer increase in ≥3 of 6 pneumococcal antigens and ≥4-fold titer increase in ≥2 of 3 influenza antigens, were assessed independently 4 weeks after vaccination. RESULTS: Following pneumococcal vaccination, 62.5% of placebo patients and 54.5% of CZP patients without effective titers at baseline achieved a humoral response (difference in proportions was -8.0 percentage points; 95% CI -22.5 to 6.6%). Following influenza vaccination, 61.4% of placebo and 53.5% of CZP patients without effective titers at baseline achieved a humoral response (difference in proportions: -8.0 percentage points; 95% CI -22.9 to 7.0%). In all patients, including those with effective titers at baseline, 58.2% of placebo and 53.3% of CZP patients developed satisfactory pneumococcal titers, and 54.1% of placebo and 50.5% of CZP patients developed satisfactory influenza antibody titers. Vaccine responses to pneumococcal and influenza antigens were reduced similarly in both treatment groups with concomitant MTX use. CONCLUSION: Humoral immune responses to pneumococcal and influenza vaccination are not impaired when given during the loading phase of CZP treatment in patients with RA.

Synergistic effect of using a transcutaneous electrical joint stimulator and an unloading brace in treating osteoarthritis of the knee.

Medical treatments and less invasive surgical approaches for knee osteoarthritis are variably effective, and total knee arthroplasty (TKA) is generally reserved for the most severe cases. The care gap between more conservative treatments and TKA leaves many patients with unresolved pain and loss of function for long periods. We conducted a study to determine if incorporating the BioniCare stimulator into an unloading brace would produce more rapid improvement and result in increased adherence and efficacy. Two hundred eighty-nine patients treated only with BioniCare served as historical controls and were compared with 225 patients treated with BioniCare combined with an unloading brace. Means and standard deviations of the changes in scores for pain intensity in the past 48 hours, pain and associated symptoms, patient global assessment, pain on going up or down stairs, and pain on walking on a flat surface and the effect sizes at 1, 3, 6, and 12 months, as well as the percentages of patients achieving at least 20% improvement, and at least 50% improvement, demonstrated that treatment with stimulator and unloading brace combined was significantly superior to treatment with the stimulator alone.

Safety, tolerability, and clinical outcomes after intraarticular injection of a recombinant adeno-associated vector containing a tumor necrosis factor antagonist gene: results of a phase 1/2 Study.

OBJECTIVE: To assess safety and clinical outcomes in patients with inflammatory arthritis after intraarticular (IA) injection of rAAV2-TNFR:Fc, a recombinant adeno-associated viral vector containing the human tumor necrosis factor (TNF) receptor-immunoglobulin (IgG1) Fc fusion (TNFR:Fc) gene. METHODS: In this phase 1/2 randomized study, adults with persistent moderate or severe inflammation in a target joint, being treated with or without systemic anti-TNF therapy, received a single IA injection of either rAAV2-TNFR:Fc (1 x 10(11), 1 x 10(12), or 1 x 10(13) DNase-resistant particles/ml joint volume) or placebo, followed by open-label rAAV2-TNFR:Fc 12-30 weeks later, depending on when the target joint met predetermined criteria for reinjection. RESULTS: 127 subjects received the first injection of blinded study drug; 95 subjects received open-label rAAV2-TNFR:Fc. Administration site reactions, consisting of transient mild to moderate increases in tenderness and swelling of the injected joint, occurred after 23/191 (12%) rAAV2-TNFR:Fc injections and were dose-dependent. Rates of other adverse events were not dose-dependent. Notable serious adverse events (SAE) included culture-negative septic arthritis in a subject receiving leflunomide and fatal disseminated histoplasmosis considered unrelated to rAAV2-TNFR:Fc in a subject receiving adalimumab. In the phase 2 portion of the study, a 30% decrease in target joint global visual analog scale was observed in 21/50 (42%) rAAV2-TNFR:Fc subjects and 3/16 (19%) placebo subjects 12 weeks after first injection (p = 0.14). CONCLUSION: IA rAAV2-TNFR:Fc resulted in administration site reactions after 12% of injections. A fatal SAE, disseminated histoplasmosis, was considered not related to study agent. Patient-reported outcome measures of clinical response showed greater improvement in treated patients than placebo patients.

Ocrelizumab, a humanized anti-CD20 monoclonal antibody, in the treatment of patients with rheumatoid arthritis: a phase I/II randomized, blinded, placebo-controlled, dose-ranging study.

OBJECTIVE: Ocrelizumab, a humanized anti-CD20 monoclonal antibody, was studied in a first-in-human trial in rheumatoid arthritis (RA) patients receiving concomitant methotrexate (MTX). METHODS: The ACTION trial was a combined phase I/II study of placebo plus MTX versus ocrelizumab plus MTX in 237 RA patients (intent-to-treat population). During phase I, 45 patients were treated with 1 of 5 escalating doses of study drug (infusions on days 1 and 15, 10-1,000 mg per each infusion). An additional 192 patients were randomized during phase II. Eligible patients had active disease, an inadequate response to treatment with at least MTX, rheumatoid factor positivity, and elevated levels of acute-phase reactants. The total study duration was 72 weeks. B cell pharmacodynamics over time was investigated. RESULTS: Baseline demographics were similar among the treatment groups. Based on the entire 72-week data set, the incidence of serious adverse events in the ocrelizumab-treated patients was 17.9%, as compared with 14.6% in placebo-treated patients. The incidence of serious infections was 2.0% in all ocrelizumab-treated patients and 4.9% in placebo-treated patients. Infusion-associated adverse events were mostly grade 1 or grade 2 and were more frequent around the time of the first infusion. No serious infusion-associated adverse events were reported in the ocrelizumab group. Evidence of clinical activity was observed at all doses evaluated. Peripheral B cell depletion after infusion was rapid at all doses, with earlier repletion of B cells at doses of 10 mg and 50 mg. Human anti-human antibodies were detected in 19% and 10%, respectively, of those receiving 10 mg and 50 mg of ocrelizumab, compared with 0-5% of those receiving 200, 500, and 1,000 mg. CONCLUSION: Ocrelizumab therapy in combination with MTX was well tolerated. Doses of 200 mg (2 infusions) and higher showed better clinical responses, better reduction of C-reactive protein levels, and very low immunogenicity.

The efficacy and safety of rituximab in patients with active rheumatoid arthritis despite methotrexate treatment: results of a phase IIB randomized, double-blind, placebo-controlled, dose-ranging trial.

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.

The safety of anakinra in high-risk patients with active rheumatoid arthritis: six-month observations of patients with comorbid conditions.

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.

Concomitant medication use in a large, international, multicenter, placebo controlled trial of anakinra, a recombinant interleukin 1 receptor antagonist, in patients with rheumatoid arthritis.

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.

Gastrointestinal tolerability and effectiveness of rofecoxib versus naproxen in the treatment of osteoarthritis: a randomized, controlled trial.

BACKGROUND: Gastrointestinal (GI) toxicity mediated by dual cyclooxygenase (COX)-1 and COX-2 inhibition of nonsteroidal anti-inflammatory drugs (NSAIDs) can cause serious alterations of mucosal integrity or, more commonly, intolerable GI symptoms that may necessitate discontinuation of therapy. Unlike NSAIDs, rofecoxib targets only the COX-2 isoform. OBJECTIVE: To assess the tolerability of rofecoxib compared with naproxen for treatment of osteoarthritis. DESIGN: Randomized, controlled trial. SETTING: 600 office and clinical research sites. PATIENTS: 5557 patients (mean age, 63 years) with a baseline diagnosis of osteoarthritis of the knee, hip, hand, or spine. INTERVENTION: Rofecoxib, 25 mg/d, or naproxen, 500 mg twice daily. Use of routine medications, including aspirin, was permitted. MEASUREMENTS: Discontinuation due to GI adverse events (primary end point) and use of concomitant medication to treat GI symptoms (secondary end point). Efficacy was determined by patient-reported global assessment of disease status and the Australian/Canadian Osteoarthritis Hand Index, as well as discontinuations due to lack of efficacy. Patients were evaluated at baseline and at weeks 6 and 12. RESULTS: Rates of cumulative discontinuation due to GI adverse events were statistically significantly lower in the rofecoxib group than in the naproxen group (5.9% vs. 8.1%; relative risk, 0.74 [95% CI, 0.60 to 0.92]; P = 0.005), as were rates of cumulative use of medication to treat GI symptoms (9.1% vs. 11.2%; relative risk, 0.79 [CI, 0.66 to 0.96]; P = 0.014]). Subgroup analysis of patients who used low-dose aspirin (13%) and those who previously discontinued using arthritis medication because of GI symptoms (15%) demonstrated a relative risk similar to the overall sample for discontinuation due to GI adverse events (relative risk, 0.56 [CI, 0.31 to 1.01] and 0.53 [CI, 0.34 to 0.84], respectively). No statistically significant difference was observed between treatments for efficacy in treating osteoarthritis or for occurrence of other adverse events. CONCLUSIONS: In patients with osteoarthritis treated for 12 weeks, rofecoxib, 25 mg/d, was as effective as naproxen, 500 mg twice daily, but had statistically significantly superior GI tolerability and led to less use of concomitant GI medications. Benefits of rofecoxib in subgroup analyses were consistent with findings in the overall sample.

Anakinra, a recombinant human interleukin-1 receptor antagonist (r-metHuIL-1ra), in patients with rheumatoid arthritis: A large, international, multicenter, placebo-controlled trial.

OBJECTIVE: To evaluate the safety of anakinra (a recombinant human interleukin-1 receptor antagonist) in a large population of patients with rheumatoid arthritis (RA), typical of those seen in clinical practice. METHODS: A total of 1,414 patients were randomly assigned to treatment with 100 mg of anakinra or placebo, administered daily by subcutaneous injection. Background medications included disease-modifying antirheumatic drugs, corticosteroids, and nonsteroidal antiinflammatory drugs, alone or in combination. The primary end point was safety, which was evaluated by adverse events (including infections), discontinuation from study due to adverse events, and death. RESULTS: Safety was evaluated in 1,399 patients (1,116 in the anakinra group and 283 in the placebo group; 15 patients were randomized but did not receive any study drug) during the initial 6-month, double-blind, placebo-controlled phase of this long-term safety study. Baseline demographics, disease characteristics, and concomitant medications were similar between the 2 groups. The study group included patients with numerous comorbid conditions and a wide range of RA disease activity. Serious adverse events occurred at a similar rate in the anakinra group and the placebo group (7.7% and 7.8%, respectively). Serious infectious episodes were observed more frequently in the anakinra group (2.1% versus 0.4% in the placebo group). The rate of withdrawal due to adverse events was 13.4% in the anakinra group and 9.2% in the placebo group. CONCLUSION: Results from this large, placebo-controlled safety study demonstrate that anakinra is safe and well tolerated in a diverse population of patients with RA, including those with comorbid conditions and those using multiple combinations of concomitant therapies. Although the frequency of serious infection was slightly higher in the anakinra group, no infection was attributed to opportunistic microorganisms or resulted in death.
