Background: Reslizumab, an anti-IL-5 monoclonal antibody, is indicated as add-on maintenance treatment for adults with severe eosinophilic asthma.
Research Question: What are the real-world outcomes associated with reslizumab use in patients with severe eosinophilic asthma in a US clinical practice?
Study Design And Methods: In this retrospective study, patient-level data from adults treated with reslizumab were obtained from center- and panel-based medical chart reviews. Eligible patients had available medical records and treatment history for ≥ 6 months before initiation of reslizumab treatment (index date) to ≥ 7 months after reslizumab initiation. The primary outcome was response to reslizumab treatment, based on clinical expert predefined definitions of response. Other outcomes included clinical asthma exacerbations (CAEs), use of maintenance oral corticosteroids (OCS), FEV percent predicted, Asthma Control Test (ACT) score, and health-care resource use (HRU).
Results: Medical charts were obtained for 215 patients. Most patients (58.6%) showed an excellent response, 16.3% showed a clinically meaningful response, 21.9% showed a partial response, and 3.3% were nonresponders or treatment failures. A significant reduction was observed in the proportion of patients experiencing a CAE in a 6-month period (from 86.0% to 40.5%; P < .001) and in the mean number of CAEs per patient (2.84 [SD, 2.41] vs 0.94 [SD, 1.86]) after reslizumab initiation. Improvements were observed in FEV percent predicted (65.1% [SD, 20.5%] vs 73.1% [SD, 23.1%]; P < .001) and in ACT scores (13.8 [SD, 4.2] vs 18.6 [SD, 4.0]; P < .001) before to after reslizumab initiation. Among patients using maintenance OCS at baseline, more than half discontinued use of these by approximately 10 months after reslizumab initiation. Significant reductions in asthma-related HRU were observed after reslizumab initiation.
Interpretation: In clinical practice, reslizumab may have been initiated in response to heavy symptom burden and CAEs. Reslizumab was associated with improved clinical and patient-reported outcomes and significant reductions in asthma-related HRU.

Objective: Understanding compliance with COVID-19 mitigation recommendations is critical for informing efforts to contain future infectious disease outbreaks. This study tested the hypothesis that higher levels of worry about COVID-19 illness among household caregivers would predict lower (a) levels of overall and discretionary social exposure activities and (b) rates of household SARS-CoV-2 infections.
Methods: Data were drawn from a surveillance study of households with children ( = 1913) recruited from 12 U.

Patients with severe eosinophilic asthma often require systemic medication, including corticosteroids and anti-type 2 (T2) cytokine biologics, to control the disease. While anti-IL5 and anti-IL4Rα antibodies suppress the effects of IL-4, IL-5 and IL-13, the molecular pathways modified by these biologics that are associated with clinical improvement remain unclear. Therefore, we aimed to describe the effects of T2-targeting biologics on the gene expression of blood immune cells.

Introduction: Patients with severe asthma may be prescribed biologic therapies to improve disease control. The EVEREST study aimed to characterize the global disease burden of patients with severe asthma without access to biologics and those who have access but do not receive biologics, as well as the remaining unmet need despite use of these therapies.
Methods: This was a historical cohort study of patients with severe asthma (aged ≥18 years) in the International Severe Asthma Registry receiving Global Initiative for Asthma (GINA) 2018 step 5 treatment, or with uncontrolled disease at GINA step 4.
