Phase 3 trial of baricitinib demonstrates efficacy with acceptable safety profile in polyarticular and extended oligoarticular juvenile idiopathic arthritis, juvenile psoriatic arthritis and enthesitis-related arthritis.

Data from this open-label extension showed the efficacy of upadacitinib observed at 56 weeks was maintained through to 152 weeks in the treatment of patients with PsA. No cumulative adverse effects were observed, and no new safety signals were identified.

Cicirello, et al. present results showing that baricitinib is comparable in treatment persistence with TNF inhibitors. However, treatment persistence up to 24 months was significantly longer for baricitinib, but the effect size of one month is not clinically meaningful.

This single-centre study by Khan, et al. suggests that high-dose methotrexate (25 mg/week, subcutaneously) may be as efficacious as tofacitinib in patients with established RA who are DMARD naïve or have not received a therapeutic dose of DMARDs.

The study demonstrated that obesity is a factor that could play a role in treatment decision-making in people living with inflammatory arthritis (IA). It appears that efficacy of TNFi is affected by patients’ weight/BMI in all forms of IA, while this is not the case for TCZ and ABA in RA, as well for IL-17 and IL-23 inhibitors in PsA.

Kristensen, et al. used mediation modelling to show that tofacitinib indirectly improved fatigue symptoms via back pain and morning stiffness. This study was carried out using FACIT-F- and BASDAI Q1-based models to determine the relationship between these variables.

This observational study suggested that obesity did not affect secukinumab treatment response and drug retention in AS patients.

Tofacitinib treatment is associated with a significant improvement in CANDEN MRI scores of spinal inflammation in axSpA patients. This study by Østergaard, et al. also validates the CANDEN MRI scoring system as an approach for measuring axSpA-associated inflammatory lesions.

Administration of IV-golimumab 2 mg/kg improves fatigue symptoms in axial spondylitis in a 52 Week study. At Week 16 of treatment, improvements in ASAS, ASDAS, BASDAI and SF-36 scores were observed at week 16 of treatment.
