Post-hoc analysis of two tofacitinib phase three studies concludes that tofacitinib treatment resulted in improvements in enthesitis in patients with PsA, regardless of baseline location or severity.

Phase IIb study of brepocitinib in patients with PsA concludes that treatment with brepocitinib 30 mg and 60 mg QD, was superior to placebo at reducing signs and symptoms of PsA and was well-tolerated over 52 weeks.

Post-hoc analysis of SPIRIT-P1 and SPIRIT-P2 concludes that ixekizumab (IXE) is effective in improving axial symptoms in patients with active PsA presenting with axial manifestations.

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.

This study concluded that, in r-axSpA, vertebral corner inflammation may lead to syndesmophyte formation but in a minority of cases via visible fat deposition. Here, investigators aimed to determine how much of the effect of vertebral corner inflammation on the development of syndesmophytes is explained by vertebral corner fat deposition.

This review by Taylor, et al. reviews the long-term safety and efficacy data for baricitinib. Results from several studies showed that baricitinib has greater efficacy and survival compared to TNF inhibitors, and that the rate of CDAI <10 for baricitinib-treated RA patients increased over the course of seven years. Data also showed that remission rates were higher in real-world evidence than in RCTs.

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.

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.

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.
