Adverse events of benralizumab in moderate to severe eosinophilic asthma: A meta-analysis.

ABSTRACT:

Background

Benralizumab, a humanized, anti-interleukin-5 (anti-IL-5) receptor ? monoclonal antibody that directly and rapidly depletes eosinophils, has shown significant efficacy in reducing asthma exacerbations and improving lung function in moderate to severe eosinophilic asthma patients. However, there is some controversy regarding the adverse events (AEs) of benralizumab and a comprehensive analysis of these AEs has not been performed. This study aimed to assess the incidence of these AEs in published randomized controlled trials (RCTs).

Methods

We searched for RCTs in the Embase, PubMed and Cochrane databases that compared benralizumab with placebo in moderate to severe eosinophilic asthma patients. The outcome was the incidence of AEs during the observation period.

Results

Eight RCTs were analyzed in this study. Patients treated with benralizumab had a lower risk of overall AEs (risk ratio (RR) 0.94; 95% confidence interval (CI) 0.90-0.98), serious adverse events (SAEs) (RR 0.82; 95% CI 0.68-0.98), asthma exacerbation (RR 0.72, 95% CI 0.61-0.85), bronchitis (RR 0.76, 95% CI 0.59-0.96) and sinusitis (RR 0.64, 95% CI 0.48-0.85), but had a higher risk of headache (RR 1.42, 95% CI 1.07-1.87) and pyrexia (RR 2.26, 95% CI 1.32-3.87) than patients treated with placebo. No increased incidence of death, hypersensitivity, injection-site reactions, nasopharyngitis, rhinitis, upper respiratory tract infection, influenza, cough, nausea, back pain or arthralgia was observed with benralizumab compared with placebo.

Conclusions

Benralizumab reduced the risk of SAEs, asthma exacerbation, bronchitis and sinusitis, and aggravated the risk of headache and pyrexia. Other AEs were comparable between the benralizumab group and placebo group. Therefore, benralizumab is a relatively safe drug, but vigilance regarding AEs is imperative during long-term treatment.

Project description:PurposeIn the Phase III SIROCCO trial (NCT01928771), benralizumab significantly reduced asthma exacerbations and improved lung function and symptoms for patients with severe, uncontrolled eosinophilic asthma. The aim of this subgroup analysis was to evaluate efficacy and safety of benralizumab for Korean patients in SIROCCO.MethodsSIROCCO was a randomized, double-blind, parallel-group, placebo-controlled trial of 1,204 patients aged 12-75 years with severe asthma uncontrolled by high-dosage inhaled corticosteroids/long-acting β₂-agonists (ICS/LABA). Patients received benralizumab 30 mg every 4 weeks (Q4W) or every 8 weeks (Q8W; first 3 doses Q4W) or placebo Q4W for 48 weeks. The primary analysis population comprised patients with blood eosinophil counts ≥ 300 cells/μL. This subgroup analysis evaluated Korean patients from this group.ResultsOf 122 Korean patients randomized, 86 had blood eosinophil counts ≥ 300 cells/μL. Benralizumab reduced the annual asthma exacerbation rate by 70% (Q4W: rate estimate 0.79, rate ratio 0.30 [95% confidence interval {CI}, 0.13-0.65], nominal P = 0.003; n = 28) and 85% (Q8W: rate estimate 0.40, rate ratio 0.15 [95% CI, 0.06-0.36], nominal P < 0.001; n = 30) vs. placebo (rate estimate 2.67, n = 28). Prebronchodilator forced expiratory volume in 1 second was increased with benralizumab treatment by 0.270 L (Q4W: 95% CI, 0.039-0.500, nominal P = 0.023; n = 28) and 0.362 L (Q8W: 95% CI, 0.143-0.582, nominal P = 0.002; n = 30) vs. placebo (n = 27). Total asthma symptom score was similar for patients receiving either benralizumab Q4W (-0.27 [95% CI, -0.83 to 0.30], nominal P = 0.356; n = 27) or benralizumab Q8W (0.10 [95% CI, -0.44 to 0.65], nominal P = 0.708; n = 30) vs. placebo (n = 28). Drug-related adverse events were experienced by 2%, 8%, and 5% of patients in the placebo, benralizumab Q4W, and benralizumab Q8W arms.ConclusionsBenralizumab reduced annual asthma exacerbation rates, increased lung function, and was well-tolerated by Korean patients with severe, uncontrolled eosinophilic asthma.

Project description:BackgroundThe comparative safety and efficacy of the biologics currently approved for asthma are unclear.ObjectiveWe compared the safety and efficacy of mepolizumab, benralizumab, and dupilumab in individuals with severe eosinophilic asthma.MethodsWe performed a systematic review of peer-reviewed literature published 2000 to 2021. We studied Bayesian network meta-analyses of exacerbation rates, prebronchodilator FEV1, the Asthma Control Questionnaire, and serious adverse events in individuals with eosinophilic asthma.ResultsEight randomized clinical trials (n = 6461) were identified. We found in individuals with eosinophils ≥300 cells/μL the following: in reducing exacerbation rates compared to placebo: dupilumab (risk ratio [RR], 0.32; 95% credible interval [CI], 0.23 to 0.45), mepolizumab (RR, 0.37; 95% CI, 0.30 to 0.45), and benralizumab (RR, 0.49; 95% CI, 0.43 to 0.55); in improving FEV1: dupilumab (mean difference in milliliters [MD] 230; 95% CI, 160 to 300), benralizumab (MD, 150; 95% CI, 100 to 200), and mepolizumab (MD, 150; 95% CI, 66 to 220); and in reducing Asthma Control Questionnaire scores: mepolizumab (MD, -0.63; 95% CI, -0.81 to -0.45), dupilumab (MD, -0.48; 95% CI, -0.83 to -0.14), and benralizumab (MD, -0.32; 95% CI, -0.43 to -0.21). In individuals with eosinophils 150-299 cells/μL, benralizumab (RR, 0.62; 95% CI, 0.52 to 0.73) and dupilumab (RR, 0.60; 95% CI, 0.38 to 0.95) were associated with lower exacerbation rates; and only benralizumab (MD, 81; 95% CI, 8 to 150) significantly improved FEV1. These differences were minimal compared to clinically important thresholds. For serious adverse events in the overall population, mepolizumab (odds ratio, 0.67; 95% CI, 0.48 to 0.92) and benralizumab (odds ratio, 0.74; 95% CI, 0.59 to 0.93) were associated with lower odds of a serious adverse event, while dupilumab was not different from placebo (odds ratio, 1.0; 95% CI, 0.74 to 1.4).ConclusionThere are minimal differences in the efficacy and safety of mepolizumab, benralizumab, and dupilumab in eosinophilic asthma.

Project description:The most promising treatment options for severe uncontrolled asthma (SUA) have emerged in recent years with the development of monoclonal antibodies for blocking selective targets responsible for the underlying inflammation, such as mepolizumab and benralizumab. However, there is variability in treatment response that is not fully controlled. The variability of the response to mepolizumab and benralizumab could be influenced by single-nucleotide polymorphisms (SNPs), and it would be useful to detect these and use them as predictive biomarkers of response. We conducted a retrospective observational cohort study of 72 Caucasian patients recruited from a tertiary hospital with severe uncontrolled eosinophilic asthma treated with mepolizumab and benralizumab. Polymorphisms in the IL5 (rs4143832, rs17690122), RAD50 (rs11739623, rs4705959), IL1RL1 (rs1420101, rs17026974, rs1921622), GATA2 (rs4857855), IKZF2 (rs12619285), FCGR2A (rs1801274), FCGR2B (rs3219018, rs1050501), FCGR3A (rs10127939, rs396991), FCER1A (rs2251746, rs2427837), FCER1B (rs1441586, rs573790, rs569108), and ZNF415 (rs1054485) genes were analyzed by real-time polymerase chain reaction (PCR) using Taqman probes. The response was analyzed after 12 months of treatment. In patients under mepolizumab treatment, a treatment response defined as a reduction in exacerbations was associated with ZNF415 rs1054485-T (p = 0.042; OR = 5.33; 95% CI = 1.06-30.02), treatment response defined as a reduction in oral corticosteroids use was associated with the number of exacerbations in the previous year (p = 0.029; OR = 3.89; 95% CI = 1.24-14.92), and treatment response defined as improvement in lung function was associated with the age at the beginning of biological therapy (p = 0.002; OR = 1.10; 95% CI = 1.04-1.18), FCER1B rs569108-AA (p < 0.001; OR = 171.06; 95% CI = 12.94-6264.11), and FCER1A rs2427837-A (p = 0.021; OR = 8.61; 95% CI = 1.71-76.62). On the other hand, in patients under benralizumab treatment, treatment response, defined as a reduction in exacerbations, was associated with ZNF415 rs1054485-T (p = 0.073; OR = 1.3 × 108; 95% CI = 1.8 × 10-19-NA), FCER1B rs569108-AA (p = 0.050; OR = 11.51; 95% CI = 1.19-269.78), allergies (p = 0.045; OR = 4.02; 95% CI = 1.05-16.74), and sex (p = 0.028; OR = 4.78; 95% CI = 1.22-20.63); and treatment response defined as improvement in lung function was associated with polyposis (p = 0.027; OR = 9.16; 95% CI = 1.58-91.4), IKZF2 rs12619285-AA (p = 0.019; OR = 9.1; 95% CI = 1.7-75.78), IL5 rs4143832-T (p = 0.017; OR = 11.1; 95% CI = 1.9-112.17), and FCER1B rs1441586-C (p = 0.045; OR = 7.81; 95% CI = 1.16-73.45). The results of this study show the potential influence of the studied polymorphisms on the response to mepolizumab and benralizumab and the clinical benefit that could be obtained by defining predictive biomarkers of treatment response.
