Randomized Controlled Trial Multicenter Study
Efficacy and safety of olokizumab in patients with rheumatoid arthritis with an inadequate response to TNF inhibitor therapy: outcomes of a randomised Phase IIb study.
The aim of this 12-week Phase IIb study was to assess the efficacy and safety of olokizumab (OKZ), a humanised anti-IL6 monoclonal antibody, in patients with rheumatoid arthritis (RA) with moderate-to-severe disease activity who had previously failed tumour necrosis factor (TNF) inhibitor therapy. The dose-exposure-response relationship for OKZ was also investigated. ⋯ OKZ produced significantly greater reductions in DAS28(CRP) from baseline at Week 12 compared with PBO. Reported AEs were consistent with the safety profile expected of this class of drug, with no new safety signals identified.

Randomized Controlled Trial Multicenter Study Comparative Study
Head-to-head, randomised, crossover study of oral versus subcutaneous methotrexate in patients with rheumatoid arthritis: drug-exposure limitations of oral methotrexate at doses ≥15 mg may be overcome with subcutaneous administration.
To compare the relative bioavailability, safety and tolerability of oral methotrexate (MTX) and subcutaneous (SC) MTX administered via an auto-injector (MTXAI) in patients with rheumatoid arthritis (RA). ⋯ Unlike oral MTX, the systemic exposure of SC MTX did not plateau over the doses studied, particularly at doses ≥15 mg/week. In this study, higher systemic MTX exposure was not associated with increases in AEs. Patients with an inadequate clinical response to oral MTX may benefit from higher drug exposure by switching to SC MTX.

Increased subchondral bone turnover may contribute to pain in osteoarthritis (OA). ⋯ Our data suggest that early targeting of osteoclasts may reduce pain associated with OA.

Interstitial lung disease (ILD) is associated with high morbidity and mortality in rheumatoid arthritis (RA). Citrullinated proteins are observed in RA lung tissues; however, the association of specific anticitrullinated peptide antibodies (ACPA) with ILD in RA is unknown. ⋯ Our findings of a broader ACPA repertoire in RA ILD suggest a possible role for ACPA in the pathogenesis of ILD.

Patients with autoimmune rheumatic diseases are more susceptible to infectious complications during the course of their disease. The introduction of biologics has been a major achievement in treating these diseases, but an increased risk of infection associated with these therapies has become evident. ⋯ A search was made of Medline (via PubMed) from 1970 to January 2014 to provide results. This review aims to provide a systematic analysis of the data about vaccines and biologics and considers recommendations for vaccination in adult patients with autoimmune rheumatic diseases treated with biologics.
