Two-Year Safety and Effectiveness of Peficitinib in Moderate-To-Severe Rheumatoid Arthritis: A Phase IIb, Open-Label Extension Study

Rheumatol Ther . 2019 Dec;6(4):503-520. doi: 10.1007/s40744-019-00167-6. Epub 2019 Aug 13.

Peficitinib (PEF) 100 mg QD demonstrated a stable safety profile and sustained effectiveness in patients with moderate-to-severe RA in a two-year extension of two global phase IIb studies. Patients enrolled in the LTE had completed one of two 12-week phase IIb PEF trials, one with MTX and one without. The primary objective of the LTE was to assess treatment-emergent adverse events and clinical laboratory evaluations for 105 weeks. As a secondary objective, an additional 2-years of effectiveness ...

Comparison of Baricitinib, Upadacitinib, and Tofacitinib Mediated Regulation of Cytokine Signalling in Human Leukocyte Subpopulations

Arthritis Res Ther. 2019 Aug 2;21(1):183

Different JAKinibs modulated distinct cytokine pathways to varying degrees, and no agent potently or continuously inhibited an individual cytokine signalling pathway throughout the dosing interval. This study aimed to compare the in vitro cellular pharmacology of BARI, TOF and UPA across relevant leukocyte subpopulations, coupled with their in vivo PK, to determine their effects on distinct cytokine pathways. Peripheral blood mononuclear cells from healthy donors were incubated with different JA...

Risk of Serious Infection in Patients with Rheumatoid Arthritis in Routine Care with Abatacept, Rituximab and Tocilizumab in Denmark and Sweden

Ann Rheum Dis. 2019 Mar;78(3):320-327. DOI: 10.1136/annrheumdis-2018-214326

Differences in baseline characteristics and numerical differences in IR of SI between ABA, RRTX and TOZ were observed. The relative risk (RR) of SIs seemed to vary modestly with drug.TNFi treated RA patients in large observational studies have suggested an initial twofold increased risk of SIs compared with biologic-naïve patients. Long-term observational studies on the risk of SIs in patients treated with non-TNFi bDMARDs are sparse.This study aimed to estimate crude as well as age and gender-a...
