Abstract
Infliximab is a mouse/human chimeric IgG1 monoclonal antibody which recognizes the proinflammatory cytokine, tumor necrosis factor α (TNFα), and inhibits receptor interactions, thereby decreasing inflammation and autoimmune response in patients. This monoclonal antibody has been successfully used to treat rheumatoid arthritis, ankylosing spondylitis, and psoriatic arthritis. However, the high treatment cost limits patient access to this biotherapy. One alternative to this problem is the use of biosimilars. In this work, we describe the stable expression and physicochemical characterization of an anti-TNFα antibody. While infliximab is produced in recombinant murine SP2/0 cells, our anti-TNFα IgG antibody was expressed in recombinant murine NS0 myeloma cells. The best anti-TNFα antibody-expressing clone was selected from three clone candidates based on the stability of IgG expression levels, specific productivity as well as TNFα-binding activity compared to commercial infliximab. Our results indicate that the selected cell clone, culture medium, and fermentation mode allowed for the production of an anti-TNFα antibody with similar characteristics to the reference commercially available product. An optimization of the selected culture medium by metabolomics may increase the volumetric productivity of the process to satisfy the demand for this product. Further experiments should be performed to evaluate the biological properties of this anti-TNFα antibody. KEY POINTS: • An anti-TNFα antibody was produced in NS0 cells using perfusion culture. • A proprietary chemically defined culture medium was used to replace commercially available protein-free medium. • The purified anti-TNFα antibody was comparable to the reference marketed product.

Microfluidic-assisted electrospinning, an alternative to coaxial, as a controlled dual drug release system to treat inflammatory arthritic diseases. Biomater Adv 2022; 134:112585.

Abstract
Inflammatory arthritic diseases are characterized by a persistent inflammation of the synovial tissues where tumor necrosis factor alpha (TNFα) and interleukin-6 (IL-6) pro-inflammatory cytokines are over-expressed, leading to progressive musculoskeletal disability. Methotrexate (MTX), a disease-modifying-anti-rheumatic drug (DMARD) commonly applied in their treatment, can be used in combination with biological-DMARDs as anti-TNFα antibody to improve the treatments efficacy. However, their systemic administration comes with severe side-effects and limited therapeutic efficacy due to their off-target distribution and short half-life. To overcome such limitations, encapsulation of clinically relevant concentrations of MTX and anti-TNFα antibody into polycaprolactone (PCL) or poly(vinyl-alcohol) (PVA) microfluidic-assisted or coaxial electrospun fibrous meshes is proposed as local controlled dual drug release systems. Release studies show that microfluidic-assisted electrospinning meshes encapsulating both drugs achieved higher concentrations than coaxials. Biological assays using human articular chondrocytes (hACs) and monocytic cells (THP-1 cell line) demonstrate that fibrous meshes encapsulating the drugs are non-toxic. The systems' efficacy is proved by a significant decrease of TNFα and IL-6 concentrations in conditioned medium of lipopolysaccharide (LPS)-stimulated THP-1 cells, especially in the presence of microfluidic-assisted electrospun meshes, when compared with THP-1 conditioned medium (59.5% and 83.9% less, respectively). Therefore, microfluidic-assisted electrospinning fibrous meshes with encapsulating drugs represent an alternative to coaxial, as a local therapy for inflammatory arthritis diseases.

Abstract
BACKGROUND The global phase 3 studies of golimumab [PURSUIT-SC and PURSUIT-maintenance (M)], an anti-tumor necrosis factor-α (anti-TNFα) antibody, have demonstrated clinical efficacy and safety as induction and maintenance therapies in patients with moderate to severely active ulcerative colitis (UC). This study aimed to evaluate the efficacy and safety of golimumab as maintenance therapy in the Japanese population. METHODS In this phase 3, double-blind (DB), placebo-controlled, parallel group, randomized withdrawal study, 144 Japanese patients with moderately to severely active UC received golimumab doses of 200 mg (at week 0) and 100 mg (at week 2) subcutaneously during the 6-week open-label induction phase. Patients who responded to golimumab induction therapy entered the DB maintenance (M) phase and were randomized (1:1) to receive 100 mg of golimumab subcutaneous injection (SC) or placebo every 4 weeks for 52 weeks. The primary endpoint was clinical response through M-week 54; secondary endpoints included clinical remission and mucosal healing at M-week 30 and 54. RESULTS Among induction responders, more patients on golimumab treatment (56.3%) maintained clinical response through M-week 54 versus the placebo group (19.4%). At both M-week 30 and 54, 50% golimumab-treated patients achieved clinical remission versus the placebo group (6.5%) and a higher proportion of patients on golimumab (59.4%) experienced mucosal healing than the placebo group (16.1%). Incidence of treatment-emergent adverse events was 96.9% in the golimumab group and 71% in the placebo group. Overall, the efficacy and safety results in this study were comparable with those observed in global studies. CONCLUSIONS Golimumab SC treatment maintained clinical efficacy through week 54 among induction responders, and no new safety signals were observed in the patients with moderate to severely active UC. CLINICAL TRIAL REGISTRATION The study is registered at ClinicalTrials.gov NCT01863771.

Abstract
OBJECTIVES To identify the specific characteristics of patients with refractory intestinal Behçet's disease (BD) who required more than glucocorticoid (GC) and/or 5-aminosalicylic acid (5-ASA) treatment. METHODS A retrospective review of the patient records in a university hospital identified 34 patients with intestinal BD. The patients treated only with glucocorticoid and/or 5-ASA (n = 8) were compared with refractory cases which required additional immunosuppressants, anti-TNFα antibodies, or surgery (n = 12). RESULTS In the refractory group, ulcers were found outside the ileocecal region more often, and more active intestinal bleeding or melena was observed, than in the GC/5ASA-controlled group (75% vs 0%, p = 0.001), (58% vs 0%, p = 0.015). The refractory group also showed higher positivity for HLA-B51 (45% vs 0%, p = 0.044), higher blood C-reactive protein (CRP) levels (14.7 ± 8.74 vs 3.93 ± 6.33 mg/dL, p = 0.046), and a higher white blood cell or WBC count (14750 ± 6760 vs 7210 ± 1830/μl, p = 0.025) at onset. The existence of either HLA-B51, melena, or elevated CRP of more than 4 mg/dL predicted the refractory form of BD with 100% sensitivity and 85.7% specificity. CONCLUSIONS Refractory intestinal BD was distinguished from the non-refractory form by distinct clinical and laboratory findings. These findings will be useful in identifying patients who require intensive therapy (e.g., anti-TNFα antibodies) in addition to GC/5ASA.
