This systematic review evaluates the efficacy and safety of biologicals for chronic rhinosinusitis with nasal polyps (CRSwNP) compared with the standard of care. PubMed, Embase, and Cochrane Library were searched for RCTs. Critical and important CRSwNP‐related outcomes were considered. The risk of bias and the certainty of the evidence were assessed using GRADE. RCTs evaluated (dupilumab‐2, omalizumab‐4, mepolizumab‐2, and reslizumab‐1) included 1236 adults, with follow‐up of 20–64 weeks. Dupilumab reduces the need for surgery (NFS) or oral corticosteroid (OCS) use (RR 0.28; 95% CI 0.20–0.39, moderate certainty) and improves with high certainty smell evaluated with UPSIT score (mean difference (MD) +10.54; 95% CI +9.24 to +11.84) and quality of life (QoL) evaluated with SNOT‐22 (MD −19.14; 95% CI −22.80 to −15.47), with fewer treatment‐related adverse events (TAEs) (RR 0.95; 95% CI 0.89–1.02, moderate certainty). Omalizumab reduces NFS (RR 0.85; 95% CI 0.78–0.92, high certainty), decreases OCS use (RR 0.38; 95% CI 0.10–1.38, moderate certainty), and improves high certainty smell (MD +3.84; 95% CI +3.64 to +4.04) and QoL (MD −15.65; 95% CI −16.16 to −15.13), with increased TAE (RR 1.73; 95% CI 0.60–5.03, moderate certainty). There is low certainty for mepolizumab reducing NFS (RR 0.78; 95% CI 0.64–0.94) and improving QoL (MD −13.3; 95% CI −23.93 to −2.67) and smell (MD +0.7; 95% CI −0.48 to +1.88), with increased TAEs (RR 1.64; 95% CI 0.41–6.50). The evidence for reslizumab is very uncertain. [ABSTRACT FROM AUTHOR]

Atopic dermatitis imposes a significant burden on patients, families and healthcare systems. Management is difficult, due to disease heterogeneity, co‐morbidities, complexity in care pathways and differences between national or regional healthcare systems. Better understanding of the mechanisms has enabled a stratified approach to the management of atopic dermatitis, supporting the use of targeted treatments with biologicals. However, there are still many issues that require further clarification. These include the definition of response, strategies to enhance the responder rate, the duration of treatment and its regimen (in the clinic or home‐based), its cost‐effectiveness and long‐term safety. The EAACI Guidelines on the use of dupilumab in atopic dermatitis follow the GRADE approach in formulating recommendations for each outcome and age group. In addition, future approaches and research priorities are discussed. [ABSTRACT FROM AUTHOR]

This systematic review evaluates the efficacy, safety and economic impact of dupilumab compared to standard of care for uncontrolled moderate‐to‐severe atopic dermatitis (AD). Pubmed, EMBASE and Cochrane Library were searched for RCTs and health economic evaluations. Critical and important AD‐related outcomes were considered. The risk of bias and the certainty of the evidence were assessed using GRADE. Seven RCTs including 1845 subjects >12 years treated with dupilumab 16 to 52 weeks were evaluated. For adults, there is high certainty that dupilumab decreases SCORAD (MD −30,72; 95% CI −34,65% to −26,79%) and EASI‐75 (RR 3.09; 95% CI 2.45 to 3.89), pruritus (RR 2.96; 95% CI 2.37 to 3.70), rescue medication (RR 3.46; 95% CI 2.79 to 4.30), sleep disturbance (MD −7.29; 95% CI −8.23 to −6.35) and anxiety/depression (MD −3.08; 95% CI −4.41 to −1.75) and improves quality of life (MD −4.80; 95% CI −5.55 to −4.06). The efficacy for adolescents is similar. Dupilumab‐related adverse events (AEs) slightly increase (low certainty). The evidence for dupilumab‐related serious AE is uncertain. The incremental cost‐effectiveness ratio ranged from 28 500 £ (low certainty) to 124 541 US$ (moderate certainty). More data on long‐term safety are needed both for children and for adults, together with more efficacy data in the paediatric population. Registration: PROSPERO (CRD42020153645).

Dupilumab, a fully human monoclonal antibody against interleukin‐4 receptor α, is approved as add‐on maintenance treatment for inadequately controlled type 2 severe asthma. This systematic review evaluated the efficacy, safety and economic impact of dupilumab compared to standard of care for uncontrolled severe asthma. PubMed, EMBASE and Cochrane Library were searched for RCTs and health economic evaluations. Critical and important asthma‐related outcomes were evaluated. The risk of bias and the certainty of the evidence were assessed using GRADE. Three RCTs including 2735 subjects >12 years old and 24‐52 weeks of follow‐up were included. Dupilumab reduced with high certainty severe asthma exacerbations (Incidence rate ratio 0.51; 95% CI 0.45‐0.59) and the percentage use of oral corticosteroid use (mean difference (MD) −28.2 mg/d; 95% CI −40.7 to −15.7). Asthma control (ACQ‐5), quality of life (AQLQ) and rescue medication use [puffs/d] improved, without reaching the minimal important clinical difference: ACQ‐5 MD −0.28 (95% CI −0.39 to −0.17); AQLQ MD +0.28 (95% CI 0.20‐0.37); and rescue medication MD −0.35 (95% CI −0.73 to +0.02). FEV1 increased (MD +0.15; 95% CI +0.11 to +0.18) (moderate certainty). There was an increased rate of dupilumab‐related adverse events (AEs) (moderate certainty) and of drug‐related serious AEs (low certainty). The incremental cost‐effectiveness ratio of dupilumab versus standard therapy was 464 000$/QALY (moderate certainty). More data on long‐term safety are needed both for children and for adults, together with more efficacy data in the paediatric population. [ABSTRACT FROM AUTHOR]

Allergic asthma is a frequent asthma phenotype. Both IgE and type 2 cytokines are increased, with some degree of overlap with other phenotypes. Systematic reviews assessed the efficacy and safety of benralizumab, dupilumab and omalizumab (alphabetical order) vs standard of care for patients with uncontrolled severe allergic asthma. PubMed, Embase and Cochrane Library were searched to identify RCTs and health economic evaluations, published in English. Critical and important asthma‐related outcomes were evaluated. The risk of bias and the certainty of the evidence were assessed using GRADE. All three biologicals reduced with high certainty the annualized asthma exacerbation rate: benralizumab incidence rate ratios (IRR) 0.63 (95% CI 0.50 − 0.81); dupilumab IRR 0.58 (95%CI 0.47 − 0.73); and omalizumab IRR 0.56 (95%CI 0.42 − 0.73). Benralizumab and dupilumab improved asthma control with high certainty and omalizumab with moderate certainty; however, none reached the minimal important difference (MID). Both benralizumab and omalizumab improved QoL with high certainty, but only omalizumab reached the MID. Omalizumab enabled ICS dose reduction with high certainty. Benralizumab and omalizumab showed an increase in drug‐related adverse events (AEs) with low to moderate certainty. All three biologicals had moderate certainty for an ICER/QALY value above the willingness to pay threshold. There was high certainty that in children 6‐12 years old omalizumab decreased the annualized exacerbation rate [IRR 0.57 (95%CI 0.45‐0.72)], improved QoL [relative risk 1.43 (95%CI 1.12 −1.83)], reduced ICS [mean difference (MD) −0.45 (95% CI −0.58 to −0.32)] and rescue medication use [ MD −0.41 (95%CI −0.66 to −0.15)].
