Messelink MA, den Broeder AA, Marinelli FE, Michgels E, Verschueren P, Aletaha D, Tekstra J, Welsing PMJ. What is the best target in a treat-to-target strategy in rheumatoid arthritis? Results from a systematic review and meta-regression analysis. RMD Open 2023; 9:e003196. [PMID: 37116986 PMCID: PMC10152050 DOI: 10.1136/rmdopen-2023-003196] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2023] [Accepted: 04/09/2023] [Indexed: 04/30/2023] Open
Abstract
OBJECTIVES A treat-to-target (T2T) strategy has been shown to be superior to usual care in rheumatoid arthritis (RA), but the optimal target remains unknown. Targets are based on a disease activity measure (eg, Disease Activity Score-28 (DAS28), Simplified Disease Activity Indices/Clinical Disease Activity Indices (SDAI/CDAI), and a cut-off such as remission or low disease activity (LDA). Our aim was to compare the effect of different targets on clinical and radiographic outcomes. METHODS Cochrane, Embase and (pre)MEDLINE databases were searched (1 June 2022) for randomised controlled trials and cohort studies after 2003 that applied T2T in RA patients for ≥12 months. Data were extracted from individual T2T study arms; risk of bias was assessed with the Cochrane Collaboration tool. Using meta-regression, we evaluated the effect of the target used on clinical and radiographic outcomes, correcting for heterogeneity between and within studies. RESULTS 115 treatment arms were used in the meta-regression analyses. Aiming for SDAI/CDAI-LDA was statistically superior to targeting DAS-LDA regarding DAS-remission and SDAI/CDAI/Boolean-remission outcomes over 1-3 years. Aiming for SDAI/CDAI-LDA was also significantly superior to DAS-remission regarding both SDAI/CDAI/Boolean-remission (over 1-3 years) and mean SDAI/CDAI (over 1 year). Targeting DAS-remission rather than DAS-LDA only improved the percentage of patients in DAS-remission, and only statistically significantly after 2-3 years of T2T. No differences were observed in Health Assessment Questionnaire and radiographic progression. CONCLUSIONS Targeting SDAI/CDAI-LDA, and to a lesser extent DAS-remission, may be superior to targeting DAS-LDA regarding several clinical outcomes. However, due to the risk of residual confounding and the lack of data on (over)treatment and safety, future studies should aim to directly and comprehensively compare targets.

Abstract
Objective Evaluate the impact of tofacitinib on American College of Rheumatology (ACR) response criteria components in patients with rheumatoid arthritis (RA). Methods This posthoc analysis pooled data from RA phase III randomized controlled trials (RCTs) assessing tofacitinib 5 or 10 mg twice daily (BID), adalimumab, or placebo, with conventional synthetic disease-modifying antirheumatic drugs, and a phase IIIb/IV RCT assessing tofacitinib 5 mg BID monotherapy, tofacitinib 5 mg BID with methotrexate, or adalimumab with methotrexate. Outcomes included: proportions of patients achieving ACR20/50/70 responses and ≥20/50/70% improvement rates in ACR components at Week 2 and Months 1, 3, and 6; mean percent improvement in ACR components and Clinical or Simplified Disease Activity Index (CDAI or SDAI) low disease activity or remission rates, at Month 3, for ACR20/50/70 responders. Results Across treatment groups, ≥20/50/70% improvement rates were numerically higher for most physician- versus patient-reported measures. In phase III RCTs, at earlier timepoints, ≥50/70% improvements in Patient Global Assessment of Disease Activity, Pain and Clinician Global Assessment were similar. Among ACR20 responders receiving tofacitinib, mean percent improvements for tender and swollen joint counts were >70% at Month 3. CDAI/SDAI remission was achieved by 27.8–45.0% of ACR70 responders receiving tofacitinib at Month 3. Conclusion Among ACR20 responders treated with tofacitinib, physician-reported components particularly exceeded 20% response improvement. At Month 3, disease state generally did not corroborate ACR70 response criteria. Divergences between physician- and patient-reported measures highlight the importance of identifying appropriate patient-reported outcome targets to manage RA symptoms in clinical practice.

Janus Kinase Inhibitors Improve Disease Activity and Patient-Reported Outcomes in Rheumatoid Arthritis: A Systematic Review and Meta-Analysis of 24,135 Patients. Int J Mol Sci 2022; 23:ijms23031246. [PMID: 35163173 PMCID: PMC8836107 DOI: 10.3390/ijms23031246] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2021] [Revised: 01/15/2022] [Accepted: 01/18/2022] [Indexed: 12/11/2022] Open
Abstract
Pain, fatigue, and physical activity are major determinants of life quality in rheumatoid arthritis (RA). Janus kinase (JAK) inhibitors have emerged as effective medications in RA and have been reported to exert direct analgesic effect in addition to reducing joint inflammation. This analysis aims to give an extensive summary of JAK inhibitors especially focusing on pain and patient reported outcomes (PRO). MEDLINE, CENTRAL, Embase, Scopus, and Web of Science databases were searched on the 26 October 2020, and 50 randomized controlled trials including 24,135 adult patients with active RA met the inclusion criteria. JAK inhibitors yielded significantly better results in all 36 outcomes compared to placebo. JAK monotherapy proved to be more effective than methotrexate in 9 out of 11 efficacy outcomes. In comparison to biological disease-modifying antirheumatic drugs, JAK inhibitors show statistical superiority in 13 of the 19 efficacy outcomes. Analgesic effect determined using the visual analogue scale and American College of Rheumatology (ACR) 20/50/70 response rates was significantly greater in the JAK group in all comparisons, and no significant difference regarding safety could be explored. This meta-analysis gives a comprehensive overview of JAK inhibitors and provides evidence for their superiority in improving PROs and disease activity indices in RA.

Abstract
Introduction The aim of this work is to propose Boolean-defined low disease activity (LDA) and to test its utility in rheumatoid arthritis (RA). Methods We used data from a longitudinal academic clinical database of RA in Peking University First Hospital over a decade. The initial proposal of Boolean-defined LDA was proposed with ascending thresholds from 2 to 5 in steps of 1 (referred to as Boolean-LDA2/3/4/5). Agreement and residual swollen joint count (SJC) pattern with the index-based [Simplified Disease Activity Index (SDAI) and Clinical Disease Activity Index (CDAI)] LDA was analyzed. To confirm discovery, we randomly classified RA patients in a 3:2 ratio into either analysis cohort or validation cohort. Results In total, 4881 visits of 672 patients were included in the analysis cohort. Of these visits, the frequencies of achieving LDA were 71.9% (SDAI), 73.6% (CDAI), 52.8% (Boolean-LDA2), 65.2% (Boolean-LDA3), 73.5% (Boolean-LDA4), and 80.7% (Boolean-LDA5). High consistency and similar SJC pattern with SDAI-LDA or CDAI-LDA were observed in Boolean-LDA3 (kappa = 0.796, 0.771). Further analysis found meeting SDAI-LDA but not Boolean-LDA3 was largely attributable to higher patient’s global assessment (PGA) scores (62.9%). In further modification of Boolean-LDA3, better agreement with SDAI-LDA or CDAI-LDA was reached when exclusively increasing PGA cutoffs to 4.0, 4.5 or replacing PGA by evaluator’s global assessment (EGA) with cutoff to 3.0. These findings were further replicated in randomly generated validation cohort of 449 patients with 3306 clinic visits. Conclusions Using cutoff of 3 to Boolean-LDA provides great clinical utility with index-based LDA, especially when exclusively increasing PGA cutoffs to 4.0, 4.5 or replacing PGA by EGA with cutoffs to 3.0. This may deserve being considered in clinical practice. Supplementary Information The online version contains supplementary material available at 10.1007/s40744-020-00270-z.

Re-establishment of efficacy of tofacitinib, an oral JAK inhibitor, after temporary discontinuation in patients with rheumatoid arthritis. Clin Rheumatol 2020; 39:2127-2137. [PMID: 32048083 PMCID: PMC7295730 DOI: 10.1007/s10067-020-04956-1] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2019] [Revised: 01/17/2020] [Accepted: 01/22/2020] [Indexed: 12/19/2022]
Abstract
Introduction/objective Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). This post-hoc analysis evaluated the effect of temporary discontinuation and reinitiation of tofacitinib on disease control in patients with RA in the vaccine sub-study of the long-term extension (LTE) study ORAL Sequel (NCT00413699). Methods The sub-study of ORAL Sequel was a randomized, parallel-group, open-label study. Patients who received tofacitinib 10 mg twice daily for ≥ 3 months in ORAL Sequel were randomized to receive continuous (tofacitinib monotherapy/with methotrexate) or interrupted (tofacitinib withdrawn for 2 weeks post-randomization then reinitiated as monotherapy/with methotrexate) treatment. Efficacy assessments included ACR20/50/70 response rates, change from baseline (∆) in C-reactive protein (CRP), Health Assessment Questionnaire-Disability Index (HAQ-DI), Disease Activity Score in 28 joints, erythrocyte sedimentation rate (DAS28-4 [ESR]), Clinical Disease Activity Index (CDAI), Patient Global Assessment of arthritis (PtGA), Pain (Visual Analog Scale [VAS]), and Physician Global Assessment of arthritis (PGA). Safety was assessed throughout. Results The sub-study included 99 patients each in the continuous and interrupted treatment groups. ACR20/50 response rates, ∆CRP, ∆HAQ-DI (day 15), ∆DAS28-4 (ESR), ∆CDAI, ∆PtGA, ∆Pain (VAS), and ∆PGA were significantly worse in interrupted vs continuous patients during dose interruption, but were generally similar to pre-interruption/continuous treatment levels 28 days post-reinitiation. A numerically higher proportion of interrupted patients reported adverse events (49.5%) vs continuous patients (35.4%). Conclusions Tofacitinib efficacy can be re-established after temporary withdrawal and reinitiation. The safety profile of patients who temporarily discontinued tofacitinib in the sub-study was consistent with previous tofacitinib LTE studies over 9 years. Clinical trial registration number NCT00413699Key Points • In this sub-study of the long-term extension (LTE) study, ORAL Sequel, the efficacy of tofacitinib was re-established after temporary withdrawal (2 weeks) and reinitation of treatment in patients with RA. • Patients with RA who temporarily discontinued tofacitinib had similar safety events to those reported in previous LTE studies. • The results of this sub-study were consistent with a post-hoc analysis of pooled data from two LTE studies, ORAL Sequel and A3921041, which assessed the efficacy of tofacitinib following a treatment discontinuation period of 14–30 days. |

Abstract
Objective Tofacitinib is an oral JAK inhibitor for the treatment of rheumatoid arthritis (RA). The phase III, 24‐month, placebo‐controlled Oral Rheumatoid Arthritis (ORAL) Scan trial was undertaken to evaluate the efficacy, including inhibition of structural progression, and safety of tofacitinib in patients with active RA and an inadequate response to methotrexate (MTX). Month 24 data from the completed study are reported here. Methods Patients were randomized 4:4:1:1 to receive tofacitinib 5 mg or 10 mg twice daily, or placebo, switched to tofacitinib 5 mg or 10 mg twice daily, with stable background MTX. Patients receiving placebo switched to tofacitinib at month 3 (nonresponders) or month 6 (remaining patients). Clinical efficacy, structural progression, and treatment‐emergent adverse events were evaluated. Analyses were performed on the full analysis set with observed data or nonresponder imputation with no advancement penalty for clinical efficacy, and imputation by linear extrapolation for structural progression. Results Overall, 797 patients were treated; 539 (67.6%) completed 24 months of treatment. Responses according to the American College of Rheumatology criteria for 20% improvement (ACR20), ACR50, and ACR70; the proportion of patients in whom remission or low disease activity was achieved according to the 4‐variable Disease Activity Score in 28 joints using the erythrocyte sedimentation rate, Clinical Disease Activity Index, or Simplified Disease Activity Index; Boolean remission; and Health Assessment Questionnaire disability index scores were maintained from month 12 to 24 and were similar between tofacitinib dosages. Limited structural damage was observed at months 12 and 24. Safety events were similar in type and frequency for both tofacitinib dosages, and were consistent with those previously reported. Conclusion Our findings indicate that clinical and radiographic treatment effects are sustained in months 12–24 in patients with RA receiving tofacitinib 5 mg or 10 mg twice daily plus MTX. The safety profile is consistent with that of other tofacitinib studies.

Abstract
INTRODUCTION Patients with rheumatoid arthritis (RA) present a higher incidence and severity of periodontitis than the general population. Our study, Outcomes of Periodontal Treatment in Patients with Rheumatoid Arthritis (OPERA), was a randomized waiting-list controlled trial using mixed methods. Patients randomized to the intervention arm received intensive periodontal treatment, and those in the control arm received the same treatment with a 6-mo delay. AIM The nested qualitative component aimed to explore patients' experiences and priorities concerning oral health and barriers and facilitators for trial participation. METHODS Using purposive sampling until thematic saturation was reached, we conducted 21 one-to-one semistructured interviews with randomized patients in either of the 2 treatment arms as well as with patients who did not consent for trial participation. RESULTS The patients described their experiences about RA, oral health, and study participation. Previous experiences with dental care professionals shaped patients' current perceptions about oral health and the place of oral health on their list of priorities compared with other conditions. Patients also highlighted some of the barriers and facilitators for study participation and for compliance with oral health maintenance. The patients, in the control arm, presented their views regarding the acceptable length of waiting time for the intervention. CONCLUSION The associations between periodontal and systemic health are increasingly recognized by the literature. Our study provided an insight into RA patients' experiences and perceptions about oral health. It also highlighted some of the barriers and facilitators for participating in a periodontal interventional study for this group. We hope that our findings will support the design of larger interventional periodontal studies in patients with RA. The complex challenges faced by the burden of RA and the associated multimorbidities in this patient group might highlight opportunities to improve access to oral health services in this patient population. KNOWLEDGE TRANSFER STATEMENT This article provided insights into the experiences and perceptions of rheumatoid arthritis patients about their oral health to improve patient participation in a definitive clinical trial.

Abstract
Background In order to better understand the perspectives of patients and physicians regarding the treatment and management of rheumatoid arthritis (RA), we present and compare results from a patient-based and a physician-based survey developed by the RA NarRAtive advisory panel. Methods The RA NarRAtive initiative is directed by a global advisory panel of 39 healthcare providers and patient organization leaders from 17 countries. A survey of patients self-reporting a diagnosis of RA and a physician-based survey, designed by the advisory panel, were fielded online by Harris Poll from September 2014 to April 2016, and from August 2015 to October 2015, respectively. Results We present findings from 1805 patients whose RA was primarily managed by a rheumatologist, and 1736 physicians managing patients with RA. Results confirmed that RA carries a substantial disease burden; half of the patients surveyed reported stopping participation in certain activities as a result of their disease. While 90% of physicians were satisfied with their communications with their patients regarding RA treatment, 61% of patients felt uncomfortable raising concerns or fears with their physician. Of the patients providing responses, 52% felt that improved dialogue/discussion would optimize their RA management, and 68% of physicians wished that they and their patients talked more about their RA goals and treatment. Overall, 88% of physicians agreed that patients involved in making treatment decisions tend to be more satisfied with their treatment experience. Conclusion The results of these surveys highlight the impact of RA on patients, and a discrepancy between patient and physician views on communication. Further research, focused on improving patient–physician dialogue, shared goal-setting, and treatment planning, is needed.

Abstract
B cells are implicated in rheumatoid arthritis (RA) based on the presence of autoantibodies and the therapeutic response to B cell depletion. IL-21 has a significant role in B cell development and function. Here we assess B cell responses to IL-21 and the mechanisms responsible for altered IL-21R expression in RA. Flow cytometry of PBMC and cultured B cells was used to quantify protein and mRNA levels of IL-21R, IL-21 signaling through pSTAT3, specificity protein 1 (SP1) and to determine cytokine production (IL-6) and maturation status of B cells in RA and healthy control subjects. SP1 binding to the IL21R promoter region in B cells was assessed with ChIP-qPCR. We demonstrate an increase in IL-21R expression in total and memory B cells from RA subjects, which correlated with responsiveness to IL-21 stimulation. Stimulation of naïve RA B cells with IL-21 and CD40L resulted in an increase in differentiation into plasmablasts and an increase in IL-6 production in comparison to healthy controls, which was dose dependent on IL-21 stimulation. IL-21R expression on memory B cells in RA synovial fluid was comparable to peripheral blood making our study pertinent to understanding B cell responses in the joint and site of inflammation. We identified an increase in SP1 protein and mRNA in RA B cells and demonstrate an increase in binding of SP1 to the IL21R promoter region, which suggests a mechanism by which IL-21R expression is enhanced on B cells in RA. Taken together, our results indicate a mechanism by which IL-21 enhances B cell development and function in RA through an SP1 mediated increase in IL-21R expression on B cells.

Abstract
Introduction Here we examine the relationship between achieving different levels of disease activity with tofacitinib (an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis), long-term structural progression, and patient-reported physical function. Methods This was a post hoc analysis of two 24-month, phase III randomized controlled trials in methotrexate (MTX)-naïve (ORAL Start [NCT01039688]) or MTX-inadequate responder (IR) patients (ORAL Scan [NCT00847613]) receiving tofacitinib 5 or 10 mg twice daily as either monotherapy or with background MTX. The modified total Sharp score (mTSS) and Health Assessment Questionnaire-Disability Index (HAQ-DI) were analyzed at month 24 according to disease activity at month 6 defined by the Clinical Disease Activity Index (CDAI) or the Disease Activity Score in 28 joints, C-reactive protein (DAS28CRP). Results Mean changes from baseline in mTSS at month 24 were less in patients with CDAI remission at month 6 than in those with CDAI moderate/high disease activity (MDA/HDA) at month 6. A DAS28CRP of < 1.9 most closely approximated CDAI remission (≤ 2.8). Tofacitinib appeared to inhibit joint damage in the presence of persistent inflammation compared with MTX. More patients receiving tofacitinib or MTX with CDAI remission or low disease activity (LDA) at month 6 reported normative HAQ-DI scores (< 0.5) at month 24 than did those with CDAI MDA/HDA. Conclusion Regardless of treatment, in both MTX-naïve and MTX-IR patients, remission or LDA at month 6 was associated with successful long-term outcomes: inhibition of structural progression and normative HAQ-DI scores. Long-term outcomes were similar when patients achieved CDAI remission or a DAS28CRP of < 1.9, confirming that this is an appropriate cut-off for remission with DAS28CRP. Tofacitinib potentially inhibits joint damage even with persistent inflammation. Funding Pfizer Inc. Trial registration Clinicaltrials.gov identifiers: NCT01039688 and NCT00847613.

Abstract
OBJECTIVE To examine patient-reported outcomes (PROs) in patients with different rheumatoid arthritis (RA) disease activity levels and identify residual symptoms. METHODS Post hoc analyses of overall and Japanese data from two randomized controlled trials including RA patients with previous inadequate responses to methotrexate (NCT01710358) or no/minimal previous disease-modifying antirheumatic drug treatment (NCT01711359) (sponsor: Eli Lilly and Company). Week 24 assessments were disease activity (Simplified Disease Activity Index, Disease Activity Score/Disease Activity Score 28 joints-erythrocyte sedimentation rate) and PROs (pain visual analog scale [VAS], morning joint stiffness [MJS], Health Assessment Questionnaire-Disability Index, Functional Assessment of Chronic Illness Therapy-Fatigue, and Medical Outcomes Study Short Form 36 Health Survey Physical and Mental Component Scores). RESULTS Patients achieving remission/low disease activity (LDA) at Week 24 had larger/significant improvements from baseline in pain, MJS, disability, fatigue, and physical and emotional quality of life versus patients with high/moderate disease activity. Some patients achieving remission and LDA, reported residual pain (pain VAS >10 mm): 20.8-39.3% and 48.7-70.0% (overall study populations), 16.0-34.5% and 47.1-62.0% (Japanese patients). Residual MJS and fatigue were also reported. CONCLUSION Remission/LDA were associated with improvements in PROs in overall and Japanese patient populations; however, some patients achieving remission had residual symptoms, including pain.

Effects of lentivirus-mediated ornithine decarboxylase gene on the proliferation and apoptosis of fibroblast-like synoviocytes in rats with arthritis. Life Sci 2018; 194:224-230. [PMID: 28986097 DOI: 10.1016/j.lfs.2017.10.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2017] [Revised: 09/23/2017] [Accepted: 10/02/2017] [Indexed: 11/24/2022]
Abstract
OBJECTIVE This study aimed to explore the effects of lentivirus-mediated ornithine decarboxylase (ODC) gene on the proliferation and apoptosis of fibroblast-like synoviocytes (FLSs) in rats with rheumatoid arthritis (RA). METHODS Twenty Lewis rats were randomized into control group (ten rats without processing) and RA group (ten rats of adjuvant-induced arthritis). The third-generation FLSs were randomized into test, control and blank groups. MTT assay and flow cytometry were employed to detect cell proliferation and apoptosis, respectively. Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of tumor necrosis factor α (TNF-α), interferon-γ (IFN-γ), and interleukin-2 (IL-2). RESULTS Lewis rats in the RA group became ill from 11days on and got seriously ill 18days after modeling. However, rats in the control group had no obvious change. MTT assay showed that the test group had higher cell proliferation than the blank and control groups (P1<0.001; P2<0.001). Flow cytometry revealed that the apoptosis of FLSs in the test group was significantly lower than that in the blank and control groups (P1<0.001; P2<0.001). ELISA showed that the test group had higher TNF-α, IFN-γ and IL-2 level than the control and blank groups (all P<0.001), but no significant difference was found between the control and blank groups (all P>0.05). CONCLUSION The results indicated that overexpression of ODC gene promotes the proliferation while suppressing apoptosis of FLSs in rats with RA.

Tofacitinib versus methotrexate in rheumatoid arthritis: patient-reported outcomes from the randomised phase III ORAL Start trial. RMD Open 2016; 2:e000308. [PMID: 27752357 PMCID: PMC5051508 DOI: 10.1136/rmdopen-2016-000308] [Citation(s) in RCA: 36] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2016] [Revised: 07/28/2016] [Accepted: 08/05/2016] [Indexed: 02/06/2023] Open
Abstract
Objectives To compare patient-reported outcomes (PROs) in methotrexate (MTX)-naive patients (defined as no prior treatment or ≤3 doses) receiving tofacitinib versus MTX. Methods In the 24-month, phase III, randomised, controlled, ORAL Start trial (NCT01039688), patients were randomised 2:2:1 to receive tofacitinib 5 mg two times per day (n=373), tofacitinib 10 mg two times per day (n=397) or MTX (n=186). PROs assessed included Patient Global Assessment of disease (PtGA), pain, Health Assessment Questionnaire-Disability Index (HAQ-DI), Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) and health-related quality of life (Short Form-36 [SF-36]). Results PROs improved following tofacitinib and MTX treatment: benefits were sustained over 24 months. Patients receiving tofacitinib reported earlier responses which were significantly different between each tofacitinib dose and MTX at month 3 through month 24. At month 6 (primary end point), significant improvements versus MTX were observed in PtGA, pain, HAQ-DI, SF-36 Physical Component Summary (PCS), 5/8 domain scores and FACIT-F with tofacitinib 5 mg two times per day; all PROs, except SF-36 Mental Component Summary Score and Medical Outcomes Survey-Sleep, with tofacitinib 10 mg two times per day. At month 6, the proportion of patients reporting improvements ≥minimum clinically important difference were significant versus MTX with tofacitinib 5 mg two times per day in PtGA and 3/8 SF-36 domains; and with tofacitinib 10 mg two times per day in PtGA, pain, HAQ-DI, SF-36 PCS, 4/8 domains and FACIT-F. Conclusions Patients with rheumatoid arthritis receiving tofacitinib 5 and 10 mg two times per day monotherapy versus MTX reported statistically significant and clinically meaningful improvements in multiple PROs over 24 months; onset of benefit with tofacitinib treatment occurred earlier. Trial registration number NCT01039688.
