JAK Inhibitors and the Risk of Malignancy: A Meta-analysis Across Disease Indications

Ann Rheum Dis. 2023;82(8):1059–1067 doi: 10.1136/ard-2023-224049

The objective of this study was to estimate the association of JAKi with the incidence of malignancy, compared with placebo, TNFi and MTX.

Braun et al. studied a large cohort of patients with nr-axSpA, that demonstrated a secukinumab reduced SI joint inflammation (BME), this reduction was sustained over 104 weeks, from an overall low baseline level of spinal inflammation or structural damage.

The results from Simon, et al. show that baricitinib treatment correlates with improvements in bone stiffness. Further improvements were also observed at the end of Week 52, with an increase in estimated failure load and no measurable progression in bone erosion being reported.

Reinisch, et al. show that filgotinib treatment has no effect on semen parameters for men with active inflammatory diseases. This contrasts with pre-clinical studies that showed fertility issues in male animals.

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.

Results from the 3-year PsABio study demonstrated that, generally, ustekinumab and TNFi treatment led to an improvement in PROs. In coming to this conclusion, researchers aimed to evaluate the real-world effect of ustekinumab or a TNFi on PRO and their association with effectiveness endpoints in PsA patients over 3 years.

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.

Pots hoc analysis of peficitinib Phase 3 trials shows that continued treatment with peficitinib up to Week 52 is linked to improved remission rates in Asian patients with RA.
