Abstract
Introduction This study aimed to demonstrate whether benralizumab maintained the safety and effectiveness profiles established in randomized controlled trials among all patients with severe uncontrolled asthma initially prescribed benralizumab in the real-world setting in Japan. Methods This was a prospective, observational, multicenter post-marketing study (ClinicalTrial.gov, NCT03588546). The safety and tolerability of benralizumab over 1 year were assessed by the incidence of adverse events (AEs), serious AEs, adverse drug reactions (ADRs), and serious ADRs. Patient background characteristics indicating a more frequent onset of ADRs with benralizumab were explored. The main effectiveness assessment was the change in Asthma Control Questionnaire-5 (ACQ-5) score from baseline. Patients with baseline ACQ-5 scores ≥1.5 were defined as having severe uncontrolled asthma. Results In total, 632 patients were evaluated for safety and 274 for effectiveness; 139 patients were included in the severe uncontrolled asthma subgroup. ADRs were reported in 12.7% and serious AEs in 13.0% of patients. Serious infections occurred in 3.8%, serious hypersensitivity in 0.3%, and malignancy in 0.3% of patients. No helminthic infections occurred. In the effectiveness population, benralizumab improved the mean (standard deviation [95% confidence interval]) ACQ-5 score by -1.16 (1.40 [-1.36, -0.96]) from baseline; forced expiratory volume in 1 second by 0.151 (0.440 [0.09, 0.21]) L; and Mini-Asthma Quality of Life questionnaire score by 1.16 (1.29 [0.94, 1.38]) at the last observation. The annual asthma exacerbation rate was 0.42. A greater ACQ-5 score improvement was observed among patients with eosinophilic asthma characteristics. Conclusion No new safety concerns were raised, and patients experienced benefits consistent with previous studies of benralizumab, thus supporting the use of benralizumab for the add-on maintenance treatment of patients with eosinophilic severe uncontrolled asthma.

Long-term effectiveness of benralizumab in severe eosinophilic asthma patients treated for 96-weeks: data from the ANANKE study. Respir Res 2023; 24:135. [PMID: 37210543 DOI: 10.1186/s12931-023-02439-w] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Accepted: 04/28/2023] [Indexed: 05/22/2023] Open
Abstract
BACKGROUND The efficacy of benralizumab has been broadly demonstrated in severe eosinophilic asthma (SEA), but only few real-life studies evaluated its long-term effects. Here we present novel data from the ANANKE study in which a large cohort of SEA patients was treated for up to 96 weeks. METHODS ANANKE (NCT04272463) is an observational retrospective Italian study investigating the key characteristics of SEA patients (collected during the 12 months prior to benralizumab initiation) and the clinical outcomes during benralizumab treatment (annual exacerbation rate [AER], lung function, asthma control, OCS use, healthcare resource utilization). A post hoc analysis was also conducted in groups of patients based on history of previous biologic therapy (bio-experienced versus naïve patients). Analyses were descriptive only. RESULTS Before benralizumab initiation, evaluable SEA patients (N = 162, 61.1% females, mean age 56.0 ± 12.7) showed a median blood eosinophil count (BEC) of 600 cells/mm3 (IQR: 430-890). Patients experienced frequent exacerbations (annualized exacerbation rate [AER]: 4.10, severe AER: 0.98), with impaired lung function and poor asthma control (median ACT score: 14) despite 25.3% reported oral corticosteroid (OCS) use. Nasal polyposis was present in 53.1% patients; 47.5% patients were atopic. After 96 weeks since the start of benralizumab, nearly 90% patients were still on treatment; benralizumab dramatically decreased exacerbations (AER: - 94.9%; severe AER: - 96.9%), improved respiratory parameters (median increase in pre-bronchodilator forced expiratory volume [pre-BD FEV1]: + 400 mL) and asthma control (median ACT score: 23) while eliminating OCS in 60% patients. Importantly, benralizumab effects were either maintained or progressively improved over time, accompanied by a nearly complete depletion of BEC. Benralizumab reduced AER both in naïve (any AER: - 95.9%; severe AER: - 97.5%) and bio-experienced patients (any AER: - 92.4%; severe AER: - 94.0%). CONCLUSIONS Profound and sustained improvements in all asthma outcomes were observed with benralizumab. The correct identification of patients' eosinophilic-driven asthma phenotype was essential to ensure the achievement of such remarkable results. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT04272463.
