REVIEW
Hannah A Blair, Emma D Deeks
The biological DMARD (bDMARD) abatacept (Orencia(®)), a recombinant fusion protein, selectively modulates a co-stimulatory signal necessary for T-cell activation. In the EU, abatacept is approved for use in patients with highly active and progressive rheumatoid arthritis (RA) not previously treated with methotrexate. Abatacept is also approved for the treatment of moderate to severe active RA in patients with an inadequate response to previous therapy with at least one conventional DMARD (cDMARD), including methotrexate or a TNF inhibitor...

Design of efficacious Treg-based therapies and establishment of clinical tolerance in autoimmune diseases have proven to be challenging. The clinical implementation of Treg immunotherapy has been hampered by various impediments related to the stability and isolation procedures of Tregs as well as the specific in vivo targets of Treg modalities. Herein, we have demonstrated that Foxp3+ Tregs potently suppress autoimmune responses in vivo through inhibition of the autophagic machinery in DCs in a cytotoxic T-lymphocyte-associated protein 4-dependent (CTLA4-dependent) manner...

BACKGROUND: Juvenile idiopathic arthritis (JIA) is characterised by joint pain, swelling and a limitation of movement caused by inflammation. Subsequent joint damage can lead to disability and growth restriction. Treatment commonly includes disease-modifying antirheumatic drugs (DMARDs), such as methotrexate. Clinical practice now favours newer drugs termed biologic DMARDs where indicated. OBJECTIVE: To assess the clinical effectiveness and cost-effectiveness of four biologic DMARDs [etanercept (Enbrel(®), Pfizer), abatacept (Orencia(®), Bristol-Myers Squibb), adalimumab (Humira(®), AbbVie) and tocilizumab (RoActemra(®), Roche) - with or without methotrexate where indicated] for the treatment of JIA (systemic or oligoarticular JIA are excluded)...

To investigate whether stroke pathogenesis and sequelae are conditional on place of initial stroke occurrence, 2,238 incident stroke cases among Rochester, Minnesota, residents in the period from 1950 to 1984 were evaluated. Virtually compete case ascertainment of first strokes in Rochester nursing homes (153 strokes), hospitals (194), and homes (1,891) was possible through a medical record linkage system. Stroke cases were reviewed by a neurologist applying uniform criteria. Although most patients had the first stroke at home (84%), there was an increasing trend over the study period of first strokes occurring while patients were hospitalized...

To investigate the risk and prognostic factors for in-hospital incident stroke and stroke mortality, surveillance was conducted on Rochester, MN, residents free of stroke when admitted to the hospital in the years 1950 through 1984. The in-hospital first stroke attack rates remained stable for the calendar years 1970,1976, and 1980. Of the first strokes that occurred in the hospital, 42% were adventitious. In approximately 60% of patients with adventitious strokes, the strokes developed within 2 days after a hospital procedure...

Currently, polymer-based prefillable syringes are being promoted to the pharmaceutical market because they provide an increased break resistance relative to traditionally used glass syringes. Despite this significant advantage, the possibility that barrel material can affect the oligomeric state of the protein drug exists. The present study was designed to compare the effect of different syringe materials and silicone oil lubrication on the protein aggregation. The stability of a recombinant fusion protein, abatacept (Orencia), and a fully human recombinant immunoglobulin G1, adalimumab (Humira), was assessed in silicone oil-free (SOF) and silicone oil-lubricated 1-mL glass syringes and polymer-based syringes in accelerated stress study...

BACKGROUND: Rheumatoid arthritis (RA) is a chronic, inflammatory disease affecting synovial joints. Patients with persistent, active disease have traditionally been treated with disease-modifying antirheumatic drugs (DMARDs) (eg, methotrexate) or biologic agents (eg, tumor necrosis factor [TNF] antagonists). However, patients may discontinue these treatments due to toxicity, infection, or lack of efficacy. Two additional biologic therapies-rituximab and abatacept-are currently available for TNF-antagonist inadequate responders...

REVIEW
Gillian M Keating
The biological disease-modifying antirheumatic drug abatacept (Orencia) has a novel mechanism of action; its activity is mediated via the selective modulation of T cell co-stimulation. This article reviews the clinical efficacy and tolerability of intravenous and subcutaneous abatacept in patients with rheumatoid arthritis (RA) and intravenous abatacept in patients with juvenile idiopathic arthritis (JIA), as well as summarizing its pharmacological properties. In patients with RA, the beneficial effects of intravenous or subcutaneous abatacept on signs and symptoms, disease activity, the progression of structural damage, physical function and/or health-related quality of life were seen in a number of well-designed trials, including in methotrexate-naive patients with early RA and poor prognostic factors and in patients with established RA and an inadequate response to either methotrexate or anti-tumour necrosis factor therapy...
