The impact of filgotinib on patient-reported outcomes and health-related quality of life for patients with active rheumatoid arthritis: a post hoc analysis of Phase 3 studies

Background The effects of filgotinib on patient-reported outcomes (PROs) from 3 trials in patients with active rheumatoid arthritis were investigated. Methods Methotrexate (MTX)-naïve patients received filgotinib 200 or 100 mg plus MTX (FIL200+MTX, FIL100+MTX), filgotinib 200 mg monotherapy (FIL200), or MTX monotherapy through 52 weeks (NCT02886728). Patients with inadequate response (IR) to MTX (MTX-IR) received FIL200+MTX, FIL100+MTX, adalimumab 40 mg +MTX (ADA+MTX), or placebo (PBO)+MTX (rerandomized to FIL200+MTX or FIL100+MTX at week 24) through 52 weeks (NCT02889796). Patients with IR to biologic disease-modifying antirheumatic drugs (bDMARD-IR) received FIL200 or FIL100 or PBO with background stable conventional synthetic (cs) DMARDs for up to 24 weeks (NCT02873936). PROs included Health Assessment Questionnaire-Disability Index (HAQ-DI), Medical Outcomes Study 36-Item Short Form Health Survey (SF-36) physical/mental component summary (PCS/MCS), Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue), Work Productivity and Activity Impairment Questionnaire-Rheumatoid Arthritis (WPAI-RA), and Patient Global Assessment of Disease Activity (PtGA). Data are reported as least-squares mean changes from baseline with standard error to the timepoint representing each study’s primary endpoint. All statistical comparisons are of filgotinib groups vs their respective control groups. Results At week 24, among MTX-naïve patients, change from baseline (standard deviation) in HAQ-DI was − 1.00 (0.03; P < 0.001) with FIL200+MTX, − 0.94 (0.04; P < 0.01) with FIL100+MTX, and − 0.91 (0.04; P < 0.05) with FIL200 alone compared with − 0.81 (0.03) with MTX alone. At week 12, among MTX-IR patients, change from baseline in HAQ-DI was − 0.69 (0.04; P < 0.001 vs PBO+MTX, P < 0.05 vs ADA) with FIL200+MTX, − 0.57 (0.04; P < 0.001 vs placebo) with FIL100+MTX, and − 0.60 (0.04) with ADA vs − 0.40 (0.04) with PBO+MTX. At week 12, among bDMARD-IR patients, change from baseline in HAQ-DI was − 0.50 (0.06; P < 0.001) with FIL200+csDMARD and − 0.46 (0.05; P < 0.001) with FIL100+csDMARD vs − 0.19 (0.06) with placebo+csDMARD. Changes in SF-36 PCS and MCS, FACIT-Fatigue, WPAI, and PtGA tended to favor filgotinib over PBO, MTX, and ADA. Greater proportions of patients experienced clinically meaningful differences with either dosage of FIL in combination with csDMARDs (including MTX) and with FIL200 monotherapy vs comparators. Conclusions Filgotinib provided improvements in PROs across patient populations. These findings suggest filgotinib can be an effective treatment option for patients with insufficient response to MTX or bDMARDs and patients who are MTX-naïve.

EFFICACY OF METHOTREXATE VERSUS LEFLUNOMIDE VERSUS COMBINATION OF BOTH IN ACTIVE RHEUMATOID ARTHRITIS

Objective: To determine the efficacy of Methotrexate versus Leflunomide versus combination of both among patients managed at Pak Emirates Military Hospital with active rheumatoid arthritis. Study Design: Prospective comparative study. Place and Duration of Study: Rheumatology/General Medicine Department, Pak Emirates Military Hospital Rawalpindi, from May 2019 to June 2020. Methodology: Patient of active rheumatoid arthritis who fulfilled American college of rheumatology criteria of 1997 were included in the study. They were randomly divided into three groups with group A receiving Methotrexate, group B receiving Leflunomide while group C received the combination of both Methotrexate and Leflunomide. Disease activity was assessed by using the Disease Activity Score-28 in all the three groups after three months of treatment. Results: Mean age of the study participants was 36.919 ± 6.85 years. One hundred and fifty (83.3%) patients were female while 30 (16.7%) were male. Out of 160 (88.9%) patients achieved remission according to Disease Activity Score-28 score at the end of three months while 20 (11.1%) did not achieve remission. Pearson chi-square test revealed that none of the factors studied including the treatment option had any statistically significant relationship with presence of remission among the target population (p-value 0.386, 0.815, 0.194 and 0.145 for age, gender, duration of symptoms and type of treatment respectively). Conclusion: Remission rate among the rheumatoid arthritis patients in response to treatment was overall good in the study. In terms of efficacy for symptoms of rheumatoid arthritis and achieving remission, after three months of treatment all the three options..................

Reduction of peripheral regulatory T cells in active rheumatoid arthritis patients with coronary artery disease

Objective To identify lymphocyte and CD4 + T cell subset characteristics, particularly regulatory T cells (Tregs), in active rheumatoid arthritis (RA) patients with coronary artery disease (CAD). Methods A total of 54 RA patients with CAD (RA-CAD group), 43 RA patients without CAD (pure RA group), and 43 healthy controls (HC group) were enrolled. The absolute number and frequency of lymphocyte subpopulations and CD4 + T cell subsets were analyzed by flow cytometry. Serum levels of cytokines were analyzed using a cytometric bead array. Clinical and laboratory data were collected retrospectively and their correlation with CD4 + T subsets were analyzed. Results There was a significant decrease in the absolute number of Treg cells (CD4 + CD25 + Foxp3 + T cells) in the RA-CAD group compared to the pure RA group (p < 0.001). Similarly, both the absolute number (p = 0.001) and frequency (p = 0.011) of Tregs in the RA-CAD group were decreased compared to the HCs, causing a Th17/Treg imbalance (p = 0.044). No difference was found in the absolute number and frequency of Treg cells between the pure RA and HC groups. However, the absolute Th17 cell count was increased in the pure RA group (p = 0.032). The serum level of cytokine IL-17 was lower in the RA-CAD group than in the pure RA group (p = 0.023). In the RA-CAD group, the Treg number was negatively correlated with the RA disease activity score and ESR value, and LDL and ApoB100 levels were negatively correlated with the number of Th17 cells. Conclusions Active RA patients with CAD sustain more severe immune tolerance damage and Th17/Treg disorder. Monitoring of lymphocyte and CD4 + T cell subsets, particularly Treg cells, is crucial to understanding immune status in this group. Focusing on RA activity and CAD risk control, immune-regulatory therapy based on the Treg level may be more beneficial for RA patients with CAD.

Addition of Fibroblast-Stromal Cell Markers to Immune Synovium Pathotypes Better Predicts Radiographic Progression at 1 Year in Active Rheumatoid Arthritis

ObjectivesThis study aims to investigate if addition of fibroblast-stromal cell markers to a classification of synovial pathotypes improves their predictive value on clinical outcomes in rheumatoid arthritis (RA).MethodsActive RA patients with a knee needle synovial biopsy at baseline and finished 1-year follow-up were recruited from a real-world prospective cohort. Positive staining for CD20, CD38, CD3, CD68, CD31, and CD90 were scored semiquantitatively (0-4). The primary outcome was radiographic progression defined as a minimum increase of 0.5 units of the modified total Sharp score from baseline to 1 year.ResultsAmong 150 recruited RA patients, 123 (82%) had qualified synovial tissue. Higher scores of CD20+ B cells, sublining CD68+ macrophages, CD31+ endothelial cells, and CD90+ fibroblasts were associated with less decrease in disease activity and greater increase in radiographic progression. A new fibroblast-based classification of synovial pathotypes giving more priority to myeloid and stromal cells classified samples as myeloid-stromal (57.7%, 71/123), lymphoid (31.7%, 39/123), and paucicellular pathotypes (10.6%, 13/123). RA patients with myeloid-stromal pathotype showed the highest rate of radiographic progression (43.7% vs. 23.1% vs. 7.7%, p = 0.011), together with the lowest rate of Boolean remission at 3, 6, and 12 months. Baseline synovial myeloid-stromal pathotype independently predicted radiographic progression at 1 year (adjusted OR: 3.199, 95% confidence interval (95% CI): 1.278, 8.010). Similar results were obtained in a subgroup analysis of treatment-naive RA.ConclusionsThis novel fibroblast-based myeloid-stromal pathotype could predict radiographic progression at 1 year in active RA patients which may contribute to the shift of therapeutic decision in RA.

Integrated safety analysis of filgotinib in patients with moderately to severely active rheumatoid arthritis receiving treatment over a median of 1.6 years

ObjectiveTo characterise safety of the Janus kinase-1 preferential inhibitor filgotinib in patients with moderately to severely active rheumatoid arthritis.MethodsData were integrated from seven trials (NCT01668641, NCT01894516, NCT02889796, NCT02873936, NCT02886728, NCT02065700, NCT03025308). Results are from placebo (PBO)-controlled (through week (W)12) and long-term, as-treated (all available data for patients receiving ≥1 dose filgotinib 200 (FIL200) or 100 mg (FIL100) daily) datasets. We calculated exposure-adjusted incidence rates (EAIRs)/100 patient-years filgotinib exposure (100PYE) for treatment-emergent adverse events (TEAEs).Results3691 patients received filgotinib for 6080.7 PYE (median 1.6, maximum 5.6 years). During the PBO-controlled period, TEAEs, including those of grade ≥3, occurred at comparable rates with filgotinib or PBO; long-term EAIRs of TEAEs grade ≥3 were 6.4 and 7.6/100PYE for FIL200 and FIL100. EAIRs for deaths were 0.6/100PYE for FIL200, FIL100 and PBO; long-term EAIRs were 0.5 and 0.3/100PYE for FIL200 and FIL100. EAIRs for serious infection were 3.9, 3.3 and 2.4/100PYE for FIL200, FIL100 and PBO; long-term EAIRs were 1.6 and 3.1/100PYE for FIL200 and FIL100. EAIRs for herpes zoster were 0.6, 1.1, and 1.1/100PYE for FIL200, FIL100 and PBO; long-term EAIRs were 1.8 and 1.1/100PYE for FIL200 and FIL100. EAIRs for major adverse cardiovascular events were 0, 1.7 and 1.1/100PYE for FIL200, FIL100 and PBO; long-term EAIRs were 0.4 and 0.6/100PYE for FIL200 and FIL100. No venous thromboembolism occurred during the PBO-controlled period; long-term EAIRs were 0.2 and 0/100PYE for FIL200 and FIL100.ConclusionsOver a median of 1.6 and maximum of 5.6 years of exposure, safety/tolerability of FIL200 and FIL100 were similar, with a lower incidence of infections with FIL200 among the long-term, as-treated dataset.

Efficacy and safety of filgotinib alone and in combination with methotrexate in Japanese patients with active rheumatoid arthritis and limited or no prior exposure to methotrexate: Subpopulation analyses of 24-week data of a global phase 3 study (FINCH 3)

ABSTRACT Objectives To evaluate the efficacy and safety of filgotinib for Japanese patients with rheumatoid arthritis (RA) and limited or no prior methotrexate (MTX) exposure. Methods Data up to 24 weeks were analysed for 71 Japanese patients from a 52-week global Phase 3 study. Patients with RA and limited or no prior MTX exposure were randomised in a 2:1:1:2 ratio to filgotinib 200 mg plus MTX, filgotinib 100 mg plus MTX, filgotinib 200 mg, or MTX. Maximum MTX dose was 15 mg/week. Primary endpoint was proportion achieving 20% improvement in American College of Rheumatology criteria (ACR20) at Week 24. Results Week 24 ACR20 rates in Japanese patients were 82.6%, 90.9%, 83.3%, and 80.0% for filgotinib 200 mg plus MTX, filgotinib 100 mg plus MTX, filgotinib 200 mg, and MTX, respectively. Greater ACR20 rates with filgotinib vs MTX occurred at Week 2. Greater proportions receiving filgotinib vs MTX achieved DAS28-CRP &lt;2.6 at Weeks 12 and 24. Adverse event rates were comparable across treatments and between the Japanese and overall populations. Conclusions While Week 24 ACR20 rates were similar, filgotinib provided faster responses and higher remission rates vs MTX. In Japanese patients with RA and limited or no prior MTX exposure, filgotinib was generally well tolerated.
