Objective: To evaluate clinical outcomes in patients who changed treatment from adalimumab to baricitinib, an oral Janus kinase (JAK)1/JAK2 inhibitor, during a phase III programme., Methods: In phase III RA-BEAM, patients were randomised 3:3:2 to placebo, baricitinib 4 mg once daily, or adalimumab 40 mg biweekly. At week 16 or subsequent visits, non-responders were rescued to open-label baricitinib 4 mg. At week 52, patients could enter a long-term extension (LTE) and continue on baricitinib or switch from adalimumab to baricitinib 4 mg with no adalimumab washout period. Percentage of patients achieving low disease activity and remission were assessed, along with physical function, patient's assessment of pain, and safety., Results: Thirty-five (7%) baricitinib-treated and 40 (12%) adalimumab-treated patients were rescued to baricitinib in RA-BEAM; 78% (381/487) of baricitinib-treated and 72% (238/330) of adalimumab-treated patients who were not rescued in RA-BEAM, entered the LTE and continued/were switched to baricitinib. In both baricitinib-rescued and adalimumab-rescued patients, there were significant improvements in all measures up to 12 weeks after rescue compared with the time of rescue. Patients who switched from adalimumab to baricitinib showed improvements in disease control through 12 weeks in the LTE. Exposure-adjusted incidence rates for treatment-emergent adverse events (TEAEs) and infections, including serious events, were similar for patients who switched from adalimumab to baricitinib and those who continued on baricitinib., Conclusions: Switching from adalimumab to baricitinib (without adalimumab washout) was associated with improvements in disease control, physical function and pain during the initial 12 weeks postswitch, without an increase in TEAEs, serious adverse events or infections., Trial Registration Numbers: NCT01710358, NCT01885078., Competing Interests: Competing interests: YT has received speaking fees and/or honoraria from Daiichi-Sankyo, Astellas, Eli Lilly, Chugai, Sanofi, Abbvie, Pfizer, YL Biologics, Bristol-Myers, Glaxo-Smithkline, UCB, Mitsubishi-Tanabe, Novartis, Eisai, Takeda, Janssen and Asahi-kasei, and has received research grants from Mitsubishi-Tanabe, Bristol-Myers, Eisai, Chugai, Takeda, Abbvie, Astellas, Daiichi-Sankyo, Ono, MSD and Taisho-Toyama; BF reports grants and personal fees from AbbVie, Eli Lilly, Pfizer and MSD, and personal fees from Biogen, BMS, Celgene, Janssen, Medac, Nordic, Novartis, Roche, SOBI, Sanofi-Genzyme and UCB outside the submitted work; EK reports funding for research from AbbVie, Amgen, Bristol-Myers Squibb, F.

Background: Rheumatoid arthritis (RA) is associated with significantly diminished health-related quality of life. Patient-reported outcomes (PROs) are considered important in RA; however, some symptoms such as morning joint stiffness (MJS) and fatigue that are considered important by patients are not captured by the American College of Rheumatology "core set" measures for RA trials. The US Food and Drug Administration has endorsed electronic capture of clinical trial data including PROs, and electronic PRO (ePRO) systems may lead to more accurate and complete data capture, improved compliance, and patient acceptance compared with paper-based methods. Our objective was to assess the implementation of ePRO measures of Duration and Severity of MJS, Severity of Worst Tiredness, and Severity of Worst Joint Pain in baricitinib RA-BEAM and RA-BUILD phase 3 randomized clinical trials (RCTs)., Methods: A daily electronic diary (handheld device; Invivodata®, Inc.) was utilized to capture PRO data in the RCTs. Three "reporting window" options were incorporated to accommodate differences in patients' routine daily schedules, and alarms were programmed for each reporting window. Duration of MJS was recorded in "hours and minutes," and Severity of MJS, Worst Tiredness, and Worst Joint Pain were captured on a 0 to 10 rating scale, with a higher score indicating more severe symptoms. The patients and site staff were trained to use the daily electronic diary., Results: Patients with moderately to severely active RA used the daily electronic diary in the RA-BEAM study (N = 1305) and RA-BUILD study (N = 684). The average compliance, calculated as total days completed by patients compared with total days expected to complete the diary, through Week 12 was high (RA-BEAM 94% patients; RA-BUILD 93% patients), potentially attributable to appropriate training, clarity of instructions, simple user interface, and electronic device design. Identified process challenges included non-timely issuance of the device, low battery, inadequate training of patients before data collection, inappropriate diary set-up, and first response entry 1 day after the baseline visit., Conclusions: High compliance rates support the use of the daily electronic PRO diary in large RCTs. Despite the anticipated issues, the daily electronic diary is expected to reduce recall bias and improve the quality of PRO data collection., Trial Registration: RA-BEAM ( NCT01710358 ) and RA-BUILD ( NCT01721057 ).

Background: This study evaluates patient-reported outcomes (PROs) in a double-blind, phase III study of baricitinib as monotherapy or combined with methotrexate (MTX) in patients with active rheumatoid arthritis (RA) with no or minimal prior conventional synthetic disease-modifying antirheumatic drugs (DMARDs) and naïve to biological DMARDs., Methods: Patients were randomized 4:3:4 to MTX administered once weekly (N = 210), baricitinib monotherapy (4 mg once daily (QD), N = 159), or combination of baricitinib (4 mg QD) and MTX (baricitinib + MTX, N = 215). PROs included the Patient's Global Assessment of Disease Activity (PtGA), patient's assessment of pain, Health Assessment Questionnaire-Disability Index (HAQ-DI), Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F), duration of morning joint stiffness (MJS), worst joint pain, worst tiredness, Work Productivity and Activity Impairment-Rheumatoid Arthritis (WPAI-RA), Short Form 36 version 2, Acute (SF-36); and EuroQol 5-Dimensions (EQ-5D) Health State Profile. Comparisons were assessed with analysis of covariance (ANCOVA) and logistic regression models., Results: Compared to MTX, patients in both baricitinib groups reported greater improvement (p ≤ 0.01) in HAQ-DI, PtGA, pain, fatigue, worst join pain, SF-36 physical component score, and EQ-5D at weeks 24 and 52. For the SF-36 mental component score, patients in both baricitinib groups reported statistically significant improvements (p ≤ 0.01) at week 52 compared to MTX-treated patients. Statistically significant improvements (p ≤ 0.05) were observed with the WPAI-RA for the baricitinib groups vs. MTX at week 24 and for the WPAI-RA daily activity and work productivity measures for baricitinib + MTX at week 52., Conclusions: In this study, baricitinib alone or in combination with MTX, when used as initial therapy, resulted in significant improvement compared to MTX in the majority of the pre-specified PRO measures., Trial Registration: ClinicalTrials.gov, NCT01711359 .

Objectives: To assess baricitinib on patient-reported outcomes (PROs) in patients with moderately to severely active rheumatoid arthritis, who had insufficient response or intolerance to ≥1 tumour necrosis factor inhibitors (TNFis) or other biological disease-modifying antirheumatic drugs (bDMARDs)., Methods: In this double-blind phase III study, patients were randomised to once-daily placebo or baricitinib 2 or 4 mg for 24 weeks. PROs included the Short Form-36, EuroQol 5-D, Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F), Health Assessment Questionnaire-Disability Index (HAQ-DI), Patient's Global Assessment of Disease Activity (PtGA), patient's assessment of pain, duration of morning joint stiffness (MJS) and Work Productivity and Activity Impairment Questionnaire-Rheumatoid Arthritis. Treatment comparisons were performed with logistic regression for categorical measures or analysis of covariance for continuous variables., Results: 527 patients were randomised (placebo, 176; baricitinib 2 mg, 174; baricitinib 4 mg, 177). Both baricitinib-treated groups showed statistically significant improvements versus placebo in most PROs. Improvements were generally more rapid and of greater magnitude for patients receiving baricitinib 4 mg than 2 mg and were maintained to week 24. At week 24, more baricitinib-treated patients versus placebo-treated patients reported normal physical functioning (HAQ-DI <0.5; p≤0.001), reductions in fatigue (FACIT-F ≥3.56; p≤0.05), improvements in PtGA (p≤0.001) and pain (p≤0.001) and reductions in duration of MJS (p<0.01)., Conclusions: Baricitinib improved most PROs through 24 weeks compared with placebo in this study of treatment-refractory patients with previously inadequate responses to bDMARDs, including at least one TNFi. PRO results aligned with clinical efficacy data for baricitinib., Trial Registration Number: NCT01721044; Results., (Published by the BMJ Publishing Group Limited.

Background: To assess the reliability, validity, and responsiveness to treatment change of the single-item measure, Severity of Worst Tiredness, in patients with rheumatoid arthritis (RA).Methods: Data from two Phase 3, randomized, placebo-controlled (RA-BUILD; and active-controlled [RA-BEAM]), clinical studies of the efficacy of baricitinib in adults with moderately to severely active RA were used. The psychometric properties of the single-item measure, Severity of Worst Tiredness, were assessed, including test-retest reliability, convergent and discriminant validity, known-groups validity, and responsiveness, using other patient- and clinician-reported outcomes frequently assessed in RA patients.Results: Test-retest reliability of the Severity of Worst Tiredness was supported through large intraclass correlation coefficients (0.89 ≤ ICC ≤ 0.91). Moderate-to-large correlations were observed between this patient-reported outcome (PRO) and other related patient- and clinician-reported assessments of RA symptoms and patient functioning, supporting construct validity of the measure (│r│ ≥ 0.41). The instrument also displayed known-groups validity through statistically significant differences between mean values of the Severity of Worst Tiredness defined using other indicators of RA severity. Finally, responsiveness was supported by large and statistically significant differences in change scores from Day 1 to Week 12 for patients comparing responders and nonresponders using the American College of Rheumatology 20 (ACR20) criteria.Conclusion: The Severity of Worst Tiredness PRO demonstrated adequate reliability, validity, and responsiveness in clinical trials of adults with moderately to severely active RA and is fit for purpose in this patient population.

Background: To assess the measurement properties of two single-item patient-reported outcome (PRO) measures that assessed the length of time (in minutes) and severity of morning joint stiffness (MJS) experienced each day.Methods: Data from two Phase 3, randomized placebo-controlled (and active-controlled [RA-BEAM]), clinical studies assessing the safety and efficacy of baricitinib in adults with moderately to severely active rheumatoid arthritis (RA) were used to evaluate the psychometric properties of the Duration of MJS and Severity of MJS PROs.Results: Test-retest reliability of Duration of MJS and Severity of MJS was supported through large intraclass correlation coefficients among stable patients (coefficient range for both studies: 0.88 to 0.93). In support of construct validity, moderate correlations were evidenced between Duration of MJS and other related patient- and clinician-reported assessments of RA symptoms and patient functioning, whereas moderate-to-strong correlations were evidenced between these same patient- and clinician-reported assessments and Severity of MJS. Statistically significant differences between the median and mean values of Duration of MJS and Severity of MJS for differing categories of RA disease severity supported known-groups validity. Finally, large and statistically significant differences in change scores from Day 1 to Week 12 for patients defined as responders versus non-responders using the American College of Rheumatology 20 criteria supported the responsiveness of both PROs.Conclusion: Duration of MJS and Severity of MJS PROs demonstrated reliability, validity, and responsiveness in adults with moderately to severely active RA, supporting the measurement of these key symptoms in clinical trials.
