Pharmacokinetics of Upadacitinib with Clinical Regimens of the Extended-Release Formulation Utilized in Rheumatoid Arthritis Phase 3 Trials

Clin Pharmacol Drug Dev. 2019 Feb;8(2):208-216. doi: 10.1002/cpdd.462

Upadacitinib (UPA) extended release (ER) formulation dosing achieved the target profile that enables single dosing in patients with RA. In early clinical studies, UPA was given as an immediate release (IR) formulation, however patients were noted to experience fluctuations in blood plasma concentrations. To enhance patient compliance in UPA Phase 3 trials, ER tablets have been developed. Here, authors aimed at characterising the pharmacokinetics of UPA single and multiple doses of ER compared wi...

Effectiveness and Safety of Tofacitinib in Rheumatoid Arthritis: a Cohort Study

Arthritis Res Ther 2018; 20(1):60 doi: 10.1186/s13075-018-1539-6

A retrospective cohort study of tofacitinib (TOF) revealed that patients previously treated with methotrexate who initiated TOF, presented no differences in hospitalised infections or effectiveness, compared with non-TNF biologics. Currently, TOF is recommended in ACR and EULAR guidelines as an alternative to biologics after first-line cDMARD therapy. Previous indirect comparisons have shown that patients with RA who experience cDMARD failure show similar efficacy when given TNFis, abatacept, to...

Effect of Discontinuation or Initiation of Methotrexate or Glucocorticoids on Tofacitinib Efficacy in Patients with Rheumatoid Arthritis: A Post Hoc Analysis

Rheumatol Ther 2018 Jun; 5(1):203–14. DOI: 10.1007/s40744-018-0093-7

Methotrexate (MTX) or Glucocorticoid (GC) discontinuation has little effect on CDAI response in patients given tofacitinib (TOF) for up to 3 years. Patients receiving TOF who showed initial improvements benefitted from initiation of MTX or GCs. Concomitant treatments such as MTX or GC are commonly used in combination with RA therapies to improve or accelerate clinical responses. However, their use is associated with many adverse events so clinicians aim to use them for a minimal duration.This po...

Radiographic Joint Damage in Early Rheumatoid Arthritis Patients: Comparing Tocilizumab- and Methotrexate-based Treat-to-target Strategies

Rheumatology (Oxford) 2018; 57(2):309–17

Tocilizumab (TCZ) therapy in DMARD-naïve patients with RA, is more effective at reducing erosion progression, particularly in the feet, compared with treat-to-target methotrexate (MTX) therapy. This analysis looked at radiographic joint damage, including separate examination of erosion progression and joint space narrowing (JSN) in the hands and feet of patients enrolled in the U-Act-Early trial. Radiographic damage is a common symptom of RA, with treat-to-target strategies aimed at preventing ...

Tofacitinib with Conventional Synthetic Disease-modifying Antirheumatic Drugs in Chinese Patients with Rheumatoid Arthritis: Patient-reported Outcomes from a Phase 3 Randomised Controlled Trial

Int J Rheum Dis 2018; 21(2):402–14

This Chinese sub-population of patients with RA from ORAL Sync reported significant improvements in patient-reported outcomes (PROs), which were maintained up to 12 months from tofacitinib (TOF) treatment initiation. ORAL Sync was a randomised, Phase 3 study investigating TOF therapy in combination with csDMARDs in patients with active RA who had previously had an inadequate response to csDMARDs. To date, this is the only Phase 3 study of TOF in patients from China with RA. This analysis include...

Tapering versus Steady-state Methotrexate in Combination with Tocilizumab for Rheumatoid Arthritis: a Randomised, Double-blind Trial

Rheumatology (Oxford) 2018;57(1):84–91

Methotrexate (MTX) tapering in patients with active, severe RA receiving intravenous tocilizumab (TCZ) was non-inferior to continuing stable MTX doses in maintaining a good/moderate EULAR response. Although MTX and bDMARD combination therapy may produce better response rates than bDMARD monotherapy, one third of patients discontinue or are non-compliant with MTX due to preference or toxicity. This randomised, non-inferiority study investigated the efficacy and tolerability of MTX tapering and ma...

2017 was a successful year for rheumatoid arthritis research, with some key advances in JAK inhibitors and IL-6 inhibitors, as outlined below. - Tofacitinib was suggested as a potential treatment for psoriatic arthritis, and NICE recommended tofacitinib as a treatment for moderate to severe rheumatoid arthritis - Baricitinib studies supported the potential use of baricitinib as a treatment for rheumatoid arthritis - Filgotinib Phase 2 studies suggested that filgotinib could be effective a...

Subcutaneous Tocilizumab in Rheumatoid Arthritis: Findings from the Common-framework Phase 4 Study Programme TOZURA Conducted in 22 Countries

Rheumatology (Oxford). 2018 Mar 1;57(3):499-507. DOI: 10.1093/rheumatology/kex443

This multi-national TOZURA study programme confirmed the efficacy and safety profile of subcutaneous tocilizumab (TC-SC) when administered as either monotherapy or in combination with csDMARDs. TOZURA was a Phase 4 study programme that evaluated open-label, TCZ-SC in patients with moderate-to-severe RA. A total of 1804 patients with active RA were enrolled in the study programme. Patients had inadequate responses to csDMARDs, anti-TNF therapies, or they were MTX-naïve. TCZ-SC was administered we...

Patient-Reported Outcomes in Newly Diagnosed Early Rheumatoid Arthritis Patients Treated to Target with a Tocilizumab- or Methotrexate-based Strategy

Rheumatology (Oxford) 2017 Dec 1;56(12):2179-2189 doi: 10.1093/rheumatology/kex319

Patient-reported outcomes (PROs) vastly improved in the first 24 weeks post-initiation of tocilizumab (TCZ) therapies compared to methotrexate (MTX) monotherapy in the U-Act-Early trial.U-Act-Early was a two-year, treat-to-target study that compared the safety and efficacy of TCZ and MTX treatment strategies in DMARD-naïve patients with early RA. Sustained remission was classed as more effective in patients given TCZ monotherapy or combination therapy with MTX compared to MTX alone. TCZ therapie...

Long-term Effectiveness of Tocilizumab in Patients with Rheumatoid Arthritis, Stratified by Number of Previous Treatment Failures with Biologic Agents: Results from the German RABBIT Cohort

Rheumatol Int 2018 Apr; 38(4):579-87

In this observational study, the German RABBIT cohort was used to assess the long-term effectiveness and retention rates of tocilizumab (TCZ) in patients with prior bDMARD failures. Results of the study suggested that TCZ could be an effective treatment option for patients with difficult-to-treat RA. A total of 885 patients were involved in the study and these were categorised dependent on the number of bDMARD failures they had prior to TCZ treatment. Patient data recorded in the cohort included...
