Abstract

Background Baricitinib (bari), a JAK1 and JAK2 inhibitor, was efficacious compared to placebo (PBO) and adalimumab (ADA) in a 52-week (Wk) Ph 3 study in patients (pts) with active rheumatoid arthritis (RA) and an inadequate response (IR) to methotrexate (MTX)1.

Objectives To evaluate changes in lipid and lipoprotein profile over 52 wks of treatment with bari or ADA compared with PBO in the aforesaid study.

Methods MTX-IR pts with active RA were randomized 3:3:2 to bari 4mg once daily (QD), PBO, or ADA 40mg biweekly. Lipid profile was evaluated at baseline and at Wks 12, 24, and 52 and nuclear magnetic resonance (NMR)-measured lipoprotein particle size and number at baseline and Wk 12.

Results Treatment with both bari and ADA resulted in significant mean increases from baseline to Wk 12 in total cholesterol (PBO -0.2%, bari 15%, ADA 7%), triglycerides (PBO 1%, bari 17%, ADA 12%), LDL-C (PBO -0.6%, bari 16%, ADA 9%), and HDL-C (PBO 0.8%, bari 17%, ADA 8%). These increases persisted through Wk 52. The NMR lipoprotein profile revealed similar changes for bari and ADA relative to PBO regarding an increase in large LDL, a decrease of all types of small LDL, and increases in IDL, VLDL and subfractions, and total HDL as well as large and small HDL particles (Table 1). Significant increases in total LDL particle numbers were not observed with either bari or ADA.

NMR analyses (mean change from baseline ± SD)

Conclusions The increase in LDL-C and HDL-C with both bari and ADA is accompanied by an increase in large LDL, total HDL particles and a decrease in small LDL. The nature of these changes may potentially indicate a more atheroprotective profile than that of the PBO group.
