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 × 1011, 1 × 1012, or 1 × 1013DNase-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.

Objective.Reduced work participation (WP) is a common problem for patients with rheumatoid arthritis (RA) and generates high costs for society. Therefore, it is important to explore determinants of WP at the start of tumor necrosis factor inhibitor (TNFi) treatment, and for changes in WP after 2 years of TNFi treatment.Methods.Within the Dutch Rheumatoid Arthritis Monitoring (DREAM) biologic register, WP data were available from 508 patients with RA younger than 65 years and without an (early) retirement pension. WP was registered at start of TNFi treatment and after 2 years of followup and was measured by single patient-reported binary questions whether they had work, paid or voluntary, or had a disability allowance or a retirement pension. Determinants measured at baseline were age, sex, disease duration, functional status [through Health Assessment Questionnaire-Disability Index (HAQ-DI)], 28-joint Disease Activity Score (DAS28), rheumatoid factor, presence of erosions, number of previous disease-modifying antirheumatic drugs, and number of comorbidities. During the 2 years of followup, HAQ-DI response and European League Against Rheumatism response were measured. Univariate analyses (excluded if p value was > 0.2) and multivariate (excluded if p value was > 0.1) logistic regression analyses were used.Results.Determinants associated with WP at baseline were having a better HAQ-DI (OR 0.32, p = 0.000) and male sex (OR 0.65, p = 0.065). After 2 years of TNFi therapy, 11.8% (n = 60) started to work and 13.6% (n = 69) stopped working. Determinants associated with starting to work were better baseline HAQ-DI (OR 0.58), positive RF (OR 2.73), and young age (OR 0.96); and for stopping work, worse baseline HAQ-DI (OR 2.74), low HAQ-DI response (OR 0.31), and comorbidity (OR 2.67), all with p < 0.1.Conclusion.Young patients with RA and a high functional status without any comorbidity will have a better chance of working. This supports the main goal in the management of RA: to suppress disease activity as soon and as completely as possible to prevent irreversible destruction of the joints, and thus maintain a good functional status of the patient. Because of the low proportion of variance explained by the models in this study, other factors besides the ones studied are associated with WP.

Differentiation factor (D factor), also called leukemia inhibitory factor (LIF), is a glycoprotein that has been increasingly recognized to possess a wide range of physiological activities. We examined the possibility that the administration of D factor may confer beneficial effects and enhance host resistance against lethal endotoxemia. A single intravenous dose of recombinant human D factor completely protected C57/Bl6 mice from the lethal effect of Escherichia coli endotoxin (lipopolysaccharide [LPS]). The protective effects were dose dependent and observed when administered 2-24 h before LPS. Previous work has shown that interleukin 1 (IL-1) and tumor necrosis factor (TNF) also protect against a subsequent LPS challenge in a dose-dependent manner. When human D factor was combined with sub-protective doses of IL-1 beta or TNF-alpha, there was dramatic synergistic protection against a subsequent lethal LPS challenge.

This study was designed to test the tumor necrosis factor (TNF) WEHI 164 clone 13 bioassay and the interleukin 6 (IL-6) B9 bioassay for sensitivity to endogenously produced dog TNF and IL-6 and then to use these assays to examine the associations between these cytokines and lipopolysaccharide (LPS)-induced fever. When dogs were injected with LPS (40, 10, 1, 0.1, and 0.01 microgram/kg), the resulting fever was dose dependent. A plot of plasma cytokine changes over time following LPS injections showed that the plasma TNF-like activity appeared to increase in an all-or-none dose response, whereas the increase in plasma IL-6-like activity appeared to be log dose dependent. Plasma TNF-like and IL-6-like activity were then separately plotted against temperature change (fever). Statistical analysis supported the interpretation that both TNF-like and IL-6-like activity were related to LPS-fever in an all-or-none manner, with IL-6 having a threshold region. We conclude that if these cytokines are circulating mediators of fever, they may induce fever in an all-or-none fashion.

Abstract Purpose To assess safety and effectiveness of anti-tumor necrosis factor (anti-TNF) therapy in IBD patients ≥ 60 years. Methods Ninety IBD patients ≥ 60 years at initiation of anti-TNF therapy, 145 IBD patients ≥ 60 years without anti-TNF therapy and 257 IBD patients < 60 years at initiation of anti-TNF therapy were retrospectively included in this multicentre study. Primary outcome was the occurrence of severe adverse events (SAEs), serious infections and malignancies. Secondary outcome was effectiveness of therapy. Cox regression analyses were used to assess differences in safety and effectiveness. In safety analyses, first older patients with and without anti-TNF therapy and then older and younger patients with anti-TNF therapy were assessed. Results In older IBD patients, the use of anti-TNF therapy was associated with serious infections (aHR 3.920, 95% CI 1.185–12.973, p = .025). In anti-TNF-exposed patients, cardiovascular disease associated with serious infections (aHR 3.279, 95% CI 1.098–9.790, p = .033) and the presence of multiple comorbidities (aHR 9.138 (1.248–66.935), p = .029) with malignancies, while patient age did not associate with safety outcomes. Effectiveness of therapy was not affected by age or comorbidity. Conclusion Older patients receiving anti-TNF therapy have a higher risk of serious infections compared with older IBD patients without anti-TNF therapy, but not compared with younger patients receiving anti-TNF therapy. However, in anti-TNF-exposed patients, comorbidity was found to be an indicator with regards to SAEs. Effectiveness was comparable between older and younger patients.

Objective.To evaluate the safety and effectiveness of rituximab (RTX) in combination with methotrexate in patients with active rheumatoid arthritis (RA) after failure of a single tumor necrosis factor-α (TNF-α) inhibitor. Changes in patient-reported outcomes after primary treatment or retreatment with RTX and factors determining retreatment in clinical practice were also evaluated.Methods.In this phase 3b open-label, multicenter trial, patients received 2 slow infusions of RTX 1000 mg 14 days apart after premedication (primary treatment). Patients with a clinically relevant response could receive retreatment between 24 and 48 weeks. The primary endpoint was evaluation of safety. Secondary outcomes were safety of retreatment, effectiveness of primary treatment and retreatment, and changes in patient-reported outcomes after primary treatment or retreatment.Results.Of 120 patients enrolled at 36 centers and receiving primary RTX treatment, 77 received retreatment, 112 completed the 24-week primary treatment period, and 25 completed the 48-week primary treatment and retreatment period following a single course of RTX. The most common adverse events were mild to moderate nausea, vomiting, nasopharyngitis, and headache. No infections or infusion reactions were considered life-threatening. At 24 weeks, 58%, 27%, and 7% of patients achieved American College of Rheumatology 20, 50, and 70 improvements, respectively, and similar improvements were seen after retreatment.Conclusion.RTX was well tolerated, with a low incidence of infusion reactions and infections. Efficacy results, including enhanced response in rheumatoid factor-positive patients, were comparable to those reported in the literature. Based on its efficacy and safety profile and retreatment schedule, RTX is an attractive treatment option for patients that have not responded to a single TNF-α inhibitor.

ABSTRACT Bikunin, a Kunitz-type protease inhibitor, exhibits anti-inflammatory activity in protection against cancer and inflammation. To investigate the molecular mechanism of this inhibition, we analyzed the effect of bikunin on tumor necrosis factor alpha (TNF-α) production in human peripheral mononuclear cells stimulated by lipopolysaccharide (LPS), an inflammatory inducer. Here, we show the following results. (i) LPS induced TNF-α expression in time- and dose-dependent manners through phosphorylation of extracellular signal-regulated kinases 1 and 2 (ERK1/2), c-Jun N-terminal kinase (JNK), and p38 mitogen-activated protein kinase pathways. (ii) Bikunin inhibits LPS-induced up-regulation of TNF-α protein expression in a dose-dependent manner, reaching 60% inhibition at the highest doses of bikunin tested (5.0 μM). (iii) Inhibition by bikunin of TNF-α induction correlates with the suppressive capacity of ERK1/2, JNK, and p38 signaling pathways, implicating repressions of at least three different signals in the inhibition. (iv) Bikunin blocks the induction of TNF-α target molecules interleukin-1β (IL-1β) and IL-6 proteins. (v) Bikunin is functional in vivo, and this glycoprotein blocks systemic TNF-α release in mice challenged with LPS. (vi) Finally, bikunin can prevent LPS-induced lethality. In conclusion, bikunin significantly inhibits LPS-induced TNF-α production, suggesting a mechanism of anti-inflammation by bikunin through control of cytokine induction during inflammation. Bikunin might be a candidate for the treatment of inflammation, including septic shock.
