This paper is based upon a long-term cohort study, namely the ANSWER cohort, an observational multi-centre registry of RA patients in the Kansai district of Japan. Analyses demonstrate a difference in observed drug retention between bDMARDs-naïve and bDMARDs-switched patients. 7 bDMARD treatments were compared in patients with no prior exposure to biologics, with abatacept showing the greatest retention rate. In patients that had switched between these same bDMARDs or to tofacitinib throughout t...

This study aimed to characterize temporary interruptions of baricitinib and describe their impact on efficacy and safety. Brief interruptions during phase 3 baricitinib trials were associated with minor increases in symptoms which were resolved following treatment. In life-long, chronic conditions such as RA, interruption of therapy is common for various reasons, such as side effects, non-compliance, or because a patient requires surgery. Concerns have been raised that these treatment breaks cou...

In SELECT-BEYOND, UPA demonstrated clinically meaningful improvements in patient reported outcomes compared to PBO in patients with RA who had an inadequate response to bDMARDs. In this post-hoc analysis of the SELECT-BEYOND study, the effect of UPA 15 or 30 mg on patient reported outcomes were assessed and compared to PBO.Eligible patients (498) with an inadequate response to bDMARDs were randomly assigned 1:1:1 to receive UPA 15 mg, UPA 30 mg or PBO. PROs collected at Wk1, Wk4, and Wk12 includ...

In this post hoc analysis, the effect of UPA 15 or 30 mg on patient reported outcomes were assessed and compared to PBO.Eligible patients (661) with an inadequate response to csDMARDs were randomly assigned 2:2:1:1 to receive background csDMARD therapy with either UPA 15 mg, UPA 30 mg or PBO. PROs collected at Wk4 and Wk1...

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...

RA patients receiving TOF 5 or 10 mg BID plus MTX showed sustained clinical and radiographic treatment effects through months 12-24. The safety profile was consistent with previous TOF studies. The 12-month data from the ORAL Scan study have been previously reported. This report assesses durability of responses, including structural damage progression, and safety with TOF through 24 months. Patients were randomized 4:4:1:1 to receive TOF 5 or 10 mg BID, or PBO advanced to TOF with stable, backgr...

This review shows that changes in lymphocyte subsets were largely within normal reference ranges and were not associated with efficacy or safety end points. BARI is a selective JAK1/JAK2 inhibitor, approved for the treatment of moderate to severe RA. BARI treatment is associated with changes to circulating lymphocyte and lymphocyte subsets, however detailed analyses of these effects, and their relevance to efficacy and safety is lacking. This study investigated the changes in lymphocyte cell sub...

Tofacitinib (TOF) treatment is associated with short-term transient increases in absolute lymphocyte counts (ALC), followed by a gradual decline to reach steady state by ~48 months. Changes in both ALC and lymphocyte subset counts (LSC) were reversible upon TOF discontinuation. Low ALC but not LSC were associated with an increased risk of serious infective episodes (SIEs) and herpes zoster (HZ). This data supported the treatment recommendations on ALC counts for starting and continuing therapy w...

Once daily baricitinib (BARI) inhibited radiographic progression of structural joint damage in patients with an inadequate response or intolerance to csDMARDs over 48 weeks.Current treatment goals aim to use DMARDs to inhibit structural joint damage and prevent long-term functional disability. In RA-BUILD¹, BARI was shown to significantly reduce radiographic joint damage progression in patients with active RA, with an intolerance or inadequate response to csDMARDs. Here, the authors report the l...

This post-hoc analysis of two, Phase 3 studies, ORAL Start and ORAL Standard shows that early treatment response can predict long-term disease activity outcomes. EULAR recommendations suggest that treat-to-target strategies require regular target assessments with treatment approaches changed if targets are not reached at 6 months. To optimize this strategy, therapy outcomes should be known, and the relationship between short and long-term outcomes defined. The current analysis focused on the dis...
