Impact of tocilizumab monotherapy on patient-reported outcomes in patients with rheumatoid arthritis from two randomised controlled trials.

ABSTRACT:

Objective

Two randomised controlled trials, AMBITION (NCT00109408) and ADACTA (NCT01119859), showed tocilizumab (TCZ) monotherapy superior to methotrexate (MTX) and adalimumab (ADA) monotherapy, respectively, for improving rheumatoid arthritis (RA) disease activity. This study compared the benefit of TCZ versus MTX or ADA monotherapy for improving patient-reported outcomes (PROs) in patients with RA.

Methods

PROs included patient global assessment (PtGA), pain, Health Assessment Questionnaire Disability Index (HAQ-DI), Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue and Short Form-36 (SF-36) physical component summary (PCS) and mental component summary (MCS) and eight domain scores. Outcomes included proportions of patients reporting changes from baseline in PRO scores ≥minimum clinically important differences (MCID) and ≥age-matched and gender-matched normative values at 24 weeks.

Results

In AMBITION, TCZ-treated patients reported significantly greater mean improvements in HAQ (-0.7 vs -0.5), FACIT-Fatigue (8.7 vs 5.7), SF-36 PCS (9.8 vs 7.8) and five SF-36 domains at week 24 than with MTX; 45.0%-84.0% of TCZ-treated patients reported improvements ≥MCID, and 24.3%-52.1% reported scores ≥normative values across all PROs versus 39.4%-81.8% and 14.5%-45.0%, respectively, with MTX. In ADACTA, TCZ-treated patients reported significantly greater improvements in PtGA (-42.3 vs -31.8), pain (-40.1 vs -28.7), SF-36 MCS (7.9 vs 5.0) and three SF-36 domains than with ADA; 57.7%-83.3% of TCZ-treated patients reported improvements ≥MCID, and 22.1%-49.3% reported scores ≥normative values across all PROs versus 13.6%-37.8%, respectively, with ADA.

Conclusions

TCZ monotherapy resulted in more patients reporting clinically meaningful PRO improvements and PRO scores ≥normative values compared with MTX or ADA monotherapy.

Project description:IntroductionTocilizumab (TCZ) monotherapy has been proven as an effective treatment for rheumatoid arthritis (RA) in clinical trials. However, there are limited data available regarding the effectiveness of TCZ monotherapy in real-world clinical settings in the United States. The objective of this study was to evaluate the impact of TCZ monotherapy on disease activity and patient-reported outcomes (PROs) in a US-based observational cohort of patients with RA seen in routine clinical practice.MethodsEligible patients had active RA, no prior use of TCZ, and initiated TCZ as monotherapy. Changes in disease activity and PROs were assessed 1 year after TCZ initiation for the overall cohort and stratified by number of prior tumor necrosis factor inhibitors (TNFis; 0, 1, or ≥2). Primary outcomes were change in Clinical Disease Activity Index (CDAI); change in patient global disease activity, pain, fatigue; and the proportions of patients with improvement in modified Health Assessment Questionnaire (mHAQ), morning stiffness, and EQ-5D.ResultsOf 255 eligible TCZ monotherapy initiators, 9.4% were TNFi naive, 36.5% had one prior TNFi, and 54.1% had ≥2 prior TNFis. Clinical and PRO measures indicated that patients were substantially impacted by their disease at baseline. The median decrease in CDAI from baseline to 1 year was 9.8 and median patient global and pain scores improved by 10 mm, indicative of clinically meaningful improvement; the median fatigue score improved by 5 mm. Approximately 26% of patients reported clinically meaningful improvement in mHAQ, 54% experienced improvement in morning stiffness, and 20% to 36% experienced improvement in EQ-5D domains (walking, self-care, usual activities, pain/discomfort, and anxiety/depression). Improvements were similar across TNFi groups.ConclusionsPatients with active, refractory RA who initiated TCZ monotherapy experienced improvements in both composite disease activity scores and PROs at 1 year, regardless of prior TNFi exposure.FundingCorrona, LLC and Genentech.

Project description:ObjectiveTo evaluate the effect of upadacitinib (UPA) monotherapy vs MTX on patient-reported outcomes (PROs) in patients with RA who were MTX-naïve or who had an inadequate response to MTX (MTX-IR).MethodsPROs from the SELECT-EARLY and SELECT-MONOTHERAPY randomized controlled trials were evaluated at Weeks 2 and 12/14. Patients were ≥18 years of age with RA symptoms for ≥6 weeks (SELECT-EARLY, MTX-naïve) or diagnosed RA for ≥3 months (SELECT-MONOTHERAPY, MTX-IR) and received UPA monotherapy (15 or 30 mg) or MTX. PROs included Patient Global Assessment of Disease Activity (PtGA), pain visual analogue scale, HAQ Disability Index (HAQ-DI), morning stiffness duration/severity, Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue (SELECT-EARLY), health-related quality of life (HRQOL) by the 36-iem Short Form Health Survey and Work Productivity and Activity Impairment (WPAI; SELECT-EARLY). Least square mean (LSM) changes and proportions of patients reporting improvements greater than or equal to the minimum clinically important differences and normative values were determined.ResultsIn 945 MTX-naïve and 648 MTX-IR patients, UPA monotherapy (15 mg, 30 mg) vs MTX resulted in greater reported LSM changes from baseline at Weeks 12/14 in PtGA, pain, HAQ-DI, morning stiffness duration/severity, FACIT-F (SELECT-EARLY), HRQOL and WPAI (SELECT-EARLY). These changes were statistically significant with both doses of UPA vs MTX at Weeks 12/14 in both RCTs. Improvements were reported as early as week 2. Compared with MTX, more UPA-treated MTX-naïve and MTX-IR patients reported improvements greater than or equal to the minimum clinically important differences and scores greater than or equal to normative values.ConclusionAmong MTX-naïve and MTX-IR patients with active RA, UPA monotherapy at 15 or 30 mg for 12/14 weeks resulted in statistically significant and clinically meaningful improvements in pain, physical function, morning stiffness, HRQOL and WPAI compared with MTX alone.Clinical trial registration numberSELECT-EARLY (NCT02706873) and SELECT-MONOTHERAPY (NCT02706951) are registered with ClinicalTrials.gov.

Project description:BACKGROUND:The phase III MONARCH randomized controlled trial (NCT02332590) demonstrated that in patients with rheumatoid arthritis (RA), sarilumab (anti-interleukin-6 receptor monoclonal antibody) monotherapy is superior to adalimumab monotherapy in reducing disease activity and signs and symptoms of RA, as well as in improving physical function, with similar rates of adverse and serious adverse events. We report the effects of sarilumab versus adalimumab on patient-reported outcomes (PROs). METHODS:Patients with active RA intolerant of, or inadequate responders to, methotrexate were randomized to sarilumab 200 mg plus placebo every 2 weeks (q2w; n?=?184) or adalimumab 40 mg plus placebo q2w (n?=?185). Dose escalation to weekly administration of adalimumab or matching placebo was permitted at week 16. PROs assessed at baseline and weeks 12 and 24 included patient global assessment of disease activity (PtGA), pain and morning stiffness visual analogue scales (VASs), Health Assessment Questionnaire Disability Index (HAQ-DI), 36-item Short Form Health Survey (SF-36), Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F), Rheumatoid Arthritis Impact of Disease (RAID), and rheumatoid arthritis-specific Work Productivity Survey (WPS-RA). Between-group differences in least-squares mean (LSM) changes from baseline were analyzed. p?<?0.05 was considered significant for PROs in a predefined hierarchy. For PROs not in the hierarchy, nominal p values are provided. Proportions of patients reporting improvements greater than or equal to the minimal clinically important difference (MCID) and achieving normative values were assessed. RESULTS:At week 24, sarilumab treatment resulted in significantly greater LSM changes from baseline than adalimumab monotherapy in HAQ-DI (p?<?0.005), PtGA (p?<?0.001), pain VAS (p?<?0.001), and SF-36 Physical Component Summary (PCS) (p?<?0.001). Greater LSM changes were reported for sarilumab than for adalimumab in RAID (nominal p?<?0.001), morning stiffness VAS (nominal p?<?0.05), and WPS-RA (nominal p?<?0.005). Between-group differences in FACIT-F and SF-36 Mental Component Summary (MCS) were not significant. More patients reported improvements greater than or equal to the MCID in HAQ-DI (nominal p?<?0.01), RAID (nominal p?<?0.01), SF-36 PCS (nominal p?<?0.005), and morning stiffness (nominal p?<?0.05), as well as greater than or equal to the normative values in HAQ-DI (p?<?0.05), with sarilumab versus adalimumab. CONCLUSIONS:In parallel with the clinical efficacy profile previously reported, sarilumab monotherapy resulted in greater improvements across multiple PROs than adalimumab monotherapy.

Project description:ObjectiveTo compare the effects of preventing radiographic progression (in its 3 components) of tocilizumab (TCZ) monotherapy with those of TCZ and methotrexate (MTX) in combination therapy (TCZ + MTX), and to evaluate possible effect modifiers in this model.MethodsRandomized trials that compared TCZ monotherapy to TCZ + MTX combination therapy for differences in radiographic progression were analyzed on an individual patient data level using mixed-effects models, and data were collected from 820 subjects with either early rheumatoid arthritis (RA) or established RA. Outcomes were classified as the absence of radiographic progression after 2 years (i.e., preventing radiographic progression) as measured by total Sharp/van der Heijde score (SHS), erosion score, and joint space narrowing (JSN) score. Effect modification by baseline joint damage, disease duration, and Disease Activity Score in 28 joints (DAS28) was studied.ResultsOverall, TCZ + MTX combination therapy was more effective in preventing radiographic progression compared to TCZ monotherapy, which was measured by total SHS score. However, in patients with early RA who had more joint damage compared to those with less joint damage at baseline (relative risk [RR] 1.02 versus RR 0.91, respectively) or in patients with a lower DAS28 score compared to those with a higher DAS28 score (RR 1.04 versus RR 0.92, respectively) at baseline, this advantage disappeared. In patients with established RA, the advantage of TCZ + MTX versus TCZ alone in the prevention of radiographic progression disappeared with a longer disease duration at baseline (RR 1.04 versus 0.83). Results of erosion scores as an outcome were in line with these findings, though findings for JSN scores were less clear.ConclusionCombination therapy with TCZ + MTX is more effective in preventing radiographic progression compared to TCZ monotherapy, but the effectiveness of TCZ monotherapy may approximate the effectiveness of TCZ + MTX in patients with early RA who have more joint damage and/or a lower DAS28 at baseline and in patients with established RA who have longer disease duration.
