Effect of dupilumab on exhaled nitric oxide, mucus plugs, and functional respiratory imaging in patients with type 2 asthma (VESTIGE): a randomised, double-blind, placebo-controlled, phase 4 trial.

Background: Asthma is a respiratory disease characterised by chronic airway inflammation and mucus hypersecretion. VESTIGE used functional respiratory imaging to assess changes in airway structure and function, including mucus plugging, in response to dupilumab.

Methods: VESTIGE was a randomised, double-blind, placebo-controlled, phase 4 trial done at 72 research sites or academic centres in 14 countries.

Current Smoker: A Clinical COPD Phenotype Affecting Disease Progression and Response to Therapy.

Chronic obstructive pulmonary disease (COPD) is a heterogeneous condition of the lungs, characterized by chronic respiratory symptoms, primarily dyspnea, cough, and sputum production, due to airway and/or alveoli abnormalities that cause persistent, and often progressive, airflow obstruction. Although the underlying mechanisms responsible for COPD remain poorly understood, over the last several decades, clinical phenotypes and endotypes have been suggested. These include frequent exacerbator and eosinophilic groups that guide tailored therapies for patients with that clinical expression.

Baseline Characteristics of Dupilumab-Treated Patients with Asthma in the Real World: The RAPID Global Registry.

Introduction: Patients with uncontrolled, moderate-to-severe asthma have a higher risk for exacerbations, negatively impacting lung function and quality of life. Dupilumab, a fully human monoclonal antibody, blocks interleukins 4 and 13, key and central drivers of type 2 inflammation. Dupilumab has been effective in the treatment of certain types of moderate-to-severe asthma across several clinical trials.

The Emerging Role of Alarmin-Targeting Biologics in the Treatment of Patients With COPD.

Topic Importance: COPD is a complex, heterogeneous lung disease characterized by persistent airflow limitation secondary to airways and parenchymal abnormalities, and respiratory symptoms, including dyspnea, fatigue, chronic cough, and sputum production. Cigarette smoke exposure is a major contributor to COPD; however, inhalation of toxic particles and other environmental and host factors can contribute to its genesis. Over time, the clinical course is frequently punctuated by exacerbations that further accelerate lung function decline and increase exacerbation risk.

Dupilumab improves sense of smell and clinical outcomes in patients with severe chronic rhinosinusitis with nasal polyps with anosmia.

Objective: Loss of sense of smell is a cardinal symptom of chronic rhinosinusitis with nasal polyps (CRSwNP) and significantly impacts health-related quality-of-life. Dupilumab significantly improved smell outcomes (loss of smell [LoS] score; University of Pennsylvania Smell Identification Test [UPSIT]) versus placebo in the phase 3 SINUS-24/-52 studies (clinicaltrials.gov, NCT02898454/NCT02912468) in patients with severe CRSwNP.

Dupilumab Efficacy and Safety in Children With Moderate to Severe Asthma and High Blood Eosinophils: A Post Hoc Analysis of VOYAGE.

Background: Elevated blood or tissue eosinophils are considered to characterize type 2 inflammation in children with asthma and are associated with increased exacerbation rates and worse asthma control. Dupilumab, a human mAb that blocks type 2 inflammatory drivers IL-4 and IL-13, reduced severe exacerbation rates and improved lung function versus placebo in children aged 6 to 11 years with uncontrolled moderate to severe asthma in the phase 3 LIBERTY ASTHMA VOYAGE study (NCT02948959).

Objective: To assess dupilumab efficacy and safety in children from VOYAGE with moderate to severe asthma and greater than or equal to 500 and less than 1500 blood eosinophils/μL at baseline.

Dupilumab Induces Long-Term On-Treatment Clinical Remission in Patients With Type 2 Asthma.

Background: Remission is proposed as a multicomponent outcome for patients with severe asthma.

Objective: This post hoc analysis of QUEST (NCT02414854) and TRAVERSE (NCT02134028) evaluated whether dupilumab treatment leads to clinical asthma remission (≥12 months with no severe exacerbations, zero oral corticosteroid use, stabilized or improved lung function, patient-reported asthma control <1.5) and assessed its durability in patients with uncontrolled, moderate to severe type 2 asthma (blood eosinophils ≥150 cells/μL or fractional exhaled nitric oxide ≥20 ppb at parent-study baseline) who are not receiving maintenance oral corticosteroids.

Dupilumab Reduces Exacerbations Independent of Changes in Biomarkers in Moderate-to-Severe Asthma.

Background: Changes from baseline in fractional exhaled nitric oxide (FeNO) and blood eosinophil count (Eos) may be related to efficacy outcomes in dupilumab-treated patients with moderate-to-severe asthma.

Objective: This post hoc analysis investigated biomarker changes in placebo- and dupilumab-treated patients with uncontrolled moderate-to-severe asthma enrolled in QUEST (NCT02414854).

Methods: Spline analyses of annualized severe exacerbation rate (AER) and change from baseline in pre-bronchodilator (BD) forced expiratory volume in 1 second (FEV) at week 52 were performed as a function of the fold change in FeNO at week 52 and the maximum fold change in Eos over weeks 0-12 (also change from baseline in pre-BD FEV at week 12).

Impact of Exacerbation History on Dupilumab Efficacy in Children with Uncontrolled Moderate-to-Severe Asthma: LIBERTY ASTHMA VOYAGE Study.

Purpose: Dupilumab, a fully human monoclonal antibody, blocks the shared receptor component for interleukins-4/-13, key and central drivers of type 2 inflammation in multiple diseases. This post hoc analysis of the Phase 3 LIBERTY ASTHMA VOYAGE study (NCT02948959) evaluated the efficacy of dupilumab in children aged 6 to 11 years with moderate-to-severe asthma with a type 2 inflammatory phenotype (blood eosinophil count ≥150 cells/µL or fractional exhaled nitric oxide [FeNO] ≥20 ppb) and a history of 1, 2, or ≥3 prior exacerbations. The impact of baseline type 2 biomarker levels on the efficacy of dupilumab in this population was also investigated.

Impact of Lung Function on Asthma Exacerbation Rates in Children Treated with Dupilumab: The VOYAGE Study.

Background: Severe, uncontrolled asthma and asthma exacerbations in children are associated with abnormal lung function and airway development, and increased risk of chronic obstructive lung disease in adulthood. The rationale for this post hoc analysis was to explore the relationship between changes in asthma exacerbation rates and lung function in children treated with dupilumab.

Methods: This post hoc analysis included children aged 6 to 11 years with uncontrolled, moderate-to-severe type 2 asthma (blood eosinophils ≥150 cells/μL or fractional exhaled nitric oxide ≥20 ppb) who received dupilumab or placebo in the phase 3 LIBERTY ASTHMA VOYAGE study (NCT02948959).

Dupilumab sustains lung function improvements in patients with moderate-to-severe asthma.

Background: TRAVERSE (NCT02134028), a phase 3 open-label extension study, assessed dupilumab safety and efficacy in patients with asthma aged ≥12 years who completed a previous dupilumab asthma study. This analysis evaluated changes in multiple lung function parameters in patients with moderate-to-severe asthma with elevated type 2 biomarkers (baseline eosinophils ≥150 cells·μL or fractional exhaled nitric oxide ≥25 ppb) who completed QUEST (parent study) and 2 years of dupilumab treatment in TRAVERSE.

Methods: Endpoints analyzed included: pre-bronchodilator forced expiratory volume in 1 s (FEV), forced vital capacity (FVC), forced expiratory flow (FEF), and pre- and post-bronchodilator FEV/FVC at parent study baseline (PSBL) at Weeks 0, 2, 48, and 96 in TRAVERSE, as well as pre- and post-bronchodilator FEV slopes in QUEST and TRAVERSE.

Blood eosinophils and fractional exhaled nitric oxide are prognostic and predictive biomarkers in childhood asthma.

Background: Blood eosinophils and fractional exhaled nitric oxide (Feno) are prognostic biomarkers for exacerbations and predict lung function responses to dupilumab in adolescents and adults with asthma.

Objective: We evaluated the relationship between baseline blood eosinophils and Feno and response to dupilumab in children with asthma.

Methods: Children aged 6 to 11 years with uncontrolled moderate-to-severe asthma (n = 408) were randomized to receive dupilumab 100/200 mg by body weight or volume-matched placebo every 2 weeks for 52 weeks.

Dupilumab Reduces Asthma Disease Burden and Recurrent SCS Use in Patients with CRSwNP and Coexisting Asthma.

Purpose: Dupilumab significantly reduced the requirement for systemic corticosteroids (SCS) in patients with severe chronic rhinosinusitis with nasal polyps (CRSwNP). Patients with CRSwNP and coexisting asthma typically have a higher disease burden and have more difficulty in managing disease. Here, we report an analysis of asthma outcomes and SCS use in patients with CRSwNP and coexisting asthma.

Long-Term Safety of Dupilumab in Patients With Moderate-to-Severe Asthma: TRAVERSE Continuation Study.

Background: Previous clinical trials have demonstrated dupilumab efficacy and safety in adults and adolescents with moderate to severe asthma for up to 3 years.

Objective: The TRAVERSE continuation study (NCT03620747), a single-arm, open-label study, assessed safety and tolerability of dupilumab 300 mg every 2 weeks up to an additional 144 weeks (∼3 years) in patients with moderate to severe asthma who previously completed TRAVERSE (NCT02134028).

Methods: Primary end points were incidence and event rates per 100 patient-years of treatment-emergent adverse events (TEAEs).
