Patient-Reported Burden of Illness in a Prevalent COPD Population Treated with Long-Acting Muscarinic Antagonist Monotherapy: A Claims-Linked Patient Survey Study.

ABSTRACT: INTRODUCTION:Symptom burden in inadequately controlled chronic obstructive pulmonary disease (COPD) considerably impacts quality of life, healthcare resource utilization (HCRU) and associated costs. This claims-linked cross-sectional survey study assessed symptom burden and HCRU among a prevalent population of COPD patients prescribed long-acting muscarinic antagonist (LAMA) monotherapy. METHODS:Patients were identified using claims data from the Optum Research Database. Eligible patients were aged???40 years with 12 months' continuous enrollment in a US health plan,???2 medical claims containing COPD diagnosis codes???30 days apart, and???2 claims for LAMA monotherapy in the latter half of the 12-month sample identification period. Patients were mailed a cross-sectional survey assessing patient-reported outcomes (PROs) [COPD assessment test (CAT) and modified medical research council dyspnea scale (mMRC)], clinical characteristics, smoking history, and demographics. Patients also completed the Exacerbations of Chronic Pulmonary Disease Tool (EXACT-PRO) daily diary for 7 days. HCRU was assessed from claims data. RESULTS:The study included 433 patients with a self-reported healthcare provider COPD diagnosis, and both claims-based and self-reported LAMA monotherapy treatment (mean age 71.0 years; 59.8% female). Most patients (85.5%) reported a high symptom burden (CAT score???10), 45.5% had high levels of dyspnea (mMRC grade???2), and 64.4% reported more severe daily symptoms by the EXACT-PRO. Most patients (71.6%) reported high scores on???2 PROs. More patients with high symptom burden had COPD-related emergency department visits than those with lower disease burden (27.6% vs 12.7%, P?=?0.012). CONCLUSIONS:In conclusion, a large proportion of patients with COPD receiving LAMA monotherapy experienced a high symptom burden and may benefit from therapy escalation. Healthcare professionals can use validated PROs to help them assess symptom burden. FUNDING:GlaxoSmithKline (GSK study number: 205862).

Project description:INTRODUCTION:Comparative data on the efficacies of long-acting muscarinic antagonist (LAMA) and long-acting ?2-agonist (LABA) combinations for the treatment of moderate-to-very-severe chronic obstructive pulmonary disease (COPD) are limited. The aim of this Bayesian network meta-analysis (NMA) is to assess the relative efficacies of available open combinations (delivered via separate inhalers) and fixed-dose combinations (FDCs, delivered via a single inhaler). METHODS:We conducted a systematic literature review with the aim of identifying randomized controlled trials (RCTs) of ?8-week duration in adults aged ?40 years with COPD that compared LAMA + LABA combinations with each other, with tiotropium (TIO), or with placebo. Data on changes from baseline in trough forced expiratory volume in 1 s (FEV1) and on St George's Respiratory Questionnaire (SGRQ) total score, the Transition Dyspnea Index (TDI) focal score, and rescue medication use at 12 and 24 weeks were extracted from these RCTs and analyzed using a NMA in a Bayesian framework. RESULTS:Data from 44 RCTs were included in the NMA. All FDCs showed improvements relative to placebo in terms of trough FEV1, SGRQ total score, and TDI focal score above clinically relevant thresholds, with the exception of TIO/olodaterol and aclidinium/formoterol, both of which failed to show clinically relevant improvements in SGRQ score at 24 weeks. All FDCs demonstrated reduced rescue medication use versus placebo. Open combinations demonstrated improved efficacy in all outcomes versus placebo, but these improvements did not consistently exceed clinically relevant thresholds for SGRQ and TDI scores. All once-daily FDCs showed improved efficacy versus TIO, but improvements were less consistently observed versus TIO with open dual combinations and combinations containing formoterol or salmeterol administered twice daily. Relative probabilities of improvement between FDCs highlighted potential between-class differences for trough FEV1 but suggested little potential for differences in patient-reported outcomes. CONCLUSION:LAMA + LABA combinations generally showed improved outcomes versus placebo and TIO. FDCs appeared to perform better than open dual combinations. A potential effectiveness gradient was observed between FDCs for objectively assessed functional outcomes, although further prospective trials are required to confirm these findings. FUNDING:GSK.

Project description:BackgroundRandomized, controlled trials comparing long-acting muscarinic antagonist (LAMA) efficacy in COPD are limited. This network meta-analysis (NMA) assessed the relative efficacy of tiotropium 18 µg once-daily (OD) and newer agents (aclidinium 400 µg twice-daily, glycopyrronium 50 µg OD, and umeclidinium 62.5 µg OD).MethodsA systematic literature review identified randomized, controlled trials of adult COPD patients receiving LAMAs. A NMA within a Bayesian framework examined change from baseline in trough forced expiratory volume in 1 second (FEV1), transitional dyspnea index focal score, St George's Respiratory Questionnaire score, and rescue medication use.ResultsTwenty-four studies (n=21,311) compared LAMAs with placebo/each other. Aclidinium, glycopyrronium, tiotropium, and umeclidinium, respectively, demonstrated favorable results versus placebo, for change from baseline (95% credible interval) in 12-week trough FEV1 (primary endpoint: 101.40 mL [77.06-125.60]; 117.20 mL [104.50-129.90]; 114.10 mL [103.10-125.20]; 136.70 mL [104.20-169.20]); 24-week trough FEV1 (128.10 mL [84.10-172.00]; 135.80 mL [123.10-148.30]; 106.40 mL [95.45-117.30]; 115.00 mL [74.51-155.30]); 24-week St George's Respiratory Questionnaire score (-4.60 [-6.76 to -2.54]; -3.14 [-3.83 to -2.45]; -2.43 [-2.92 to -1.93]; -4.69 [-7.05 to -2.31]); 24-week transitional dyspnea index score (1.00 [0.41-1.59]; 1.01 [0.79-1.22]; 0.82 [0.62-1.02]; 1.00 [0.49-1.51]); and 24-week rescue medication use (data not available; -0.41 puffs/day [-0.62 to -0.20]; -0.52 puffs/day [-0.74 to -0.30]; -0.30 puffs/day [-0.81 to 0.21]). For 12-week trough FEV1, differences in change from baseline (95% credible interval) were -12.8 mL (-39.39 to 13.93), aclidinium versus tiotropium; 3.08 mL (-7.58 to 13.69), glycopyrronium versus tiotropium; 22.58 mL (-11.58 to 56.97), umeclidinium versus tiotropium; 15.90 mL (-11.60 to 43.15), glycopyrronium versus aclidinium; 35.40 mL (-5.06 to 76.07), umeclidinium versus aclidinium; and 19.50 mL (-15.30 to 54.38), umeclidinium versus glycopyrronium. Limitations included inhaler-related factors and safety; longer-term outcomes were not considered.ConclusionThe new LAMAs studied had at least comparable efficacy to tiotropium, the established class standard. Choice should depend on physician's and patient's preference.

Project description:BACKGROUND:Revefenacin, a once-daily, long-acting muscarinic antagonist delivered via standard jet nebulizer, increased trough forced expiratory volume in 1?s (FEV1) in patients with moderate to very severe chronic obstructive pulmonary disease (COPD) in prior phase 3 trials. We evaluated the efficacy of revefenacin in patients with markers of more severe COPD. METHODS:A post hoc subgroup analysis of two replicate, randomized, phase 3 trials was conducted over 12?weeks. Endpoints included least squares change from baseline in trough FEV1, St. George's Respiratory Questionnaire (SGRQ) responders, and transition dyspnea index (TDI) responders at Day 85. This analysis included patient subgroups at high risk for COPD exacerbations and compared patients who received revefenacin 175??g and placebo: severe and very severe airflow limitation (percent predicted FEV1 30%-<?50% and?<?30%), 2011 Global Initiative for Chronic Obstructive Lung Disease (GOLD) D, reversibility (? 12% and???200?mL increase in FEV1) to short-acting bronchodilators, concurrent use of long-acting ? agonists and/or inhaled corticosteroids, older age (>?65 and?>?75?years), and comorbidity risk factors. RESULTS:Revefenacin demonstrated significant improvements in FEV1 versus placebo at Day 85 among the intention-to-treat (ITT) population and all subgroups. Additionally, there was a greater number of SGRQ and TDI responders in the ITT population and the majority of subgroups analyzed among patients who received revefenacin versus placebo. For the SGRQ responders, the odds of response (odds ratio?>?2.0) were significantly greater in the revefenacin arm versus the placebo arm among the severe airflow obstruction, very severe airflow obstruction and 2011 GOLD D subgroups. For the TDI responders, the odds of response (odds ratio?>?2.0) were significantly greater among the severe airflow obstruction subgroup and patients aged >?75?years. CONCLUSIONS:Revefenacin showed significantly greater improvements in FEV1 versus placebo in the ITT population and all subgroups. Furthermore, there were a greater number of SGRQ and TDI responders in the ITT population, and in the majority of patient subgroups among patients who received revefenacin versus placebo. Based on the data presented, revefenacin could be a therapeutic option among patients with markers of more severe COPD. TRIAL REGISTRATION:Clinical trials registered with www.clinicaltrials.gov (Studies 0126 [NCT02459080; prospectively registered 22 May 2015] and 0127 [NCT02512510; prospectively registered 28 July 2015]).

Project description:Two once-daily long-acting muscarinic antagonists (LAMAs) are currently available for the treatment of chronic obstructive pulmonary disease (COPD) - tiotropium and glycopyrronium. Previous studies have compared glycopyrronium with open-label tiotropium. In the GLOW5 study, we compare glycopyrronium with blinded tiotropium.In this blinded, double-dummy, parallel group, 12-week study, patients with moderate-to-severe COPD were randomized 1:1 to glycopyrronium 50 ?g once daily or tiotropium 18 ?g once daily. The primary objective was to demonstrate the non-inferiority of glycopyrronium versus blinded tiotropium with respect to trough forced expiratory volume in 1 second (FEV1) following 12 weeks of treatment (non-inferiority margin: -50 mL). Secondary objectives were to evaluate glycopyrronium versus tiotropium for other spirometric outcomes, breathlessness (Transition Dyspnea Index; TDI), health status (St George's Respiratory Questionnaire; SGRQ), daily rescue medication use, COPD exacerbations and COPD symptoms over 12 weeks of treatment.657 patients were randomized (glycopyrronium: 327; tiotropium: 330); 96% (630 patients) completed the study. Least squares mean trough FEV1 for both glycopyrronium and tiotropium was 1.405 L at Week 12, meeting the criterion for non-inferiority (mean treatment difference: 0 mL, 95% CI: -32, 31 mL). Glycopyrronium demonstrated rapid bronchodilation following first dose on Day 1, with significantly higher FEV1 at all time points from 0-4 h post-dose versus tiotropium (all p < 0.001). FEV1 area under the curve from 0-4 h (AUC0-4h) post-dose with glycopyrronium was significantly superior to tiotropium on Day 1 (p < 0.001) and was comparable to tiotropium at Week 12. Glycopyrronium demonstrated comparable improvements to tiotropium in TDI focal score, SGRQ total score, rescue medication use and the rate of COPD exacerbations (all p = not significant). Patients on glycopyrronium also had a significantly lower total COPD symptom score versus patients on tiotropium after 12 weeks (p = 0.035). Adverse events were reported by a similar percentage of patients receiving glycopyrronium (40.4%) and tiotropium (40.6%).In patients with moderate-to-severe COPD, 12-week blinded treatment with once-daily glycopyrronium 50 ?g or tiotropium 18 ?g, provided similar efficacy and safety, with glycopyrronium having a faster onset of action on Day 1 versus tiotropium.

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.
