Abstract
INTRODUCTION Biologics targeting type 2 inflammation have revolutionized the way we treat patients with Chronic Rhinosinusitis with Nasal Polyps (CRSwNP). Particularly in severe and difficult-to-control cases, these drugs have provided a new reality for these patients, allowing for the effective and safe treatment of extensive diseases that were not completely managed with the typical strategy of surgery and topical medications. OBJECTIVES The experience achieved with the approval of these medications by ANVISA for use in CRSwNP and the knowledge obtained regarding outcomes, adverse effects, and the ideal patient profile prompted the update of the previously published guideline, with a detailed review of the most recent scientific literature, the personal experiences of experts, and the adaptation to the reality of the Brazilian healthcare system, both public and private. RESULTS We proposed a new eligibility criterion for biologics in patients with CRSwNP based on four pillars of indication: the impact of the disease on the patient's life, whether in the presence of specific symptoms or in overall quality of life; the extent of sinonasal disease; the presence of type 2 comorbidities, considering other associated diseases that may also benefit from anti-T2 biologics, and the presence of biomarkers to define type 2 inflammation, especially those associated with worse disease prognoses. CONCLUSIONS This innovative and pioneering method has two major advantages. First, it ensures a comprehensive evaluation of patients; second, it is flexible, as advancements in our understanding of the disease and changes in cost-effectiveness can be addressed by simply adjusting the required score for indication, without the need to modify the entire evaluation scheme.

Association Between T2-related Comorbidities and Effectiveness of Biologics in Severe Asthma. Am J Respir Crit Care Med 2024; 209:262-272. [PMID: 38016003 DOI: 10.1164/rccm.202305-0808oc] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2023] [Accepted: 11/27/2023] [Indexed: 11/30/2023] Open
Abstract
Rationale: Previous studies investigating the impact of comorbidities on the effectiveness of biologic agents have been relatively small and of short duration and have not compared classes of biologic agents. Objectives: To determine the association between type 2-related comorbidities and biologic agent effectiveness in adults with severe asthma (SA). Methods: This cohort study used International Severe Asthma Registry data from 21 countries (2017-2022) to quantify changes in four outcomes before and after biologic therapy-annual asthma exacerbation rate, FEV1% predicted, asthma control, and long-term oral corticosteroid daily dose-in patients with or without allergic rhinitis, chronic rhinosinusitis (CRS) with or without nasal polyps (NPs), NPs, or eczema/atopic dermatitis. Measurements and Main Results: Of 1,765 patients, 1,257, 421, and 87 initiated anti-IL-5/5 receptor, anti-IgE, and anti-IL-4/13 therapies, respectively. In general, pre- versus post-biologic therapy improvements were noted in all four asthma outcomes assessed, irrespective of comorbidity status. However, patients with comorbid CRS with or without NPs experienced 23% fewer exacerbations per year (95% CI, 10-35%; P < 0.001) and had 59% higher odds of better post-biologic therapy asthma control (95% CI, 26-102%; P < 0.001) than those without CRS with or without NPs. Similar estimates were noted for those with comorbid NPs: 22% fewer exacerbations and 56% higher odds of better post-biologic therapy control. Patients with SA and CRS with or without NPs had an additional FEV1% predicted improvement of 3.2% (95% CI, 1.0-5.3; P = 0.004), a trend that was also noted in those with comorbid NPs. The presence of allergic rhinitis or atopic dermatitis was not associated with post-biologic therapy effect for any outcome assessed. Conclusions: These findings highlight the importance of systematic comorbidity evaluation. The presence of CRS with or without NPs or NPs alone may be considered a predictor of the effectiveness of biologic agents in patients with SA.

[PMID: 37378551 DOI: 10.1080/1744666x.2023.2231150] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Revised: 06/07/2023] [Accepted: 06/26/2023] [Indexed: 06/29/2023]
Abstract
INTRODUCTION Chronic sinusitis with nasal polyposis (CRSwNP) is a common heterogeneous disease that mainly manifests as chronic inflammation of the sinus mucosa. The effect of conventional treatments for CRSwNP, such as oral corticosteroids, intranasal corticosteroids (INCS) and polypectomy, is not always obvious, and postoperative recurrence is common in some CRSwNP patients. In recent years, some biologics have been shown to be very effective in treating refractory CRSwNP, of which dupilumab has attracted much attention as the first monoclonal drug approved to treat nasal polyps. AREAS COVERED In this review, we discuss the research status of dupilumab in treatment of CRSwNP and how dupilumab differs from other treatment methods. EXPERT OPINION The European Union and United States have approved dupilumab as the first biological agent for treatment of CRSwNP. Dupilumab can improve symptoms of nasal congestion or obstruction, nasal secretion, and olfactory loss in patients with CRSwNP. It can also improve a patient's health-related quality of life (HR-QoL) and reduce the need for systemic corticosteroids and nasal polyp surgery. While subcutaneous injection of dupilumab is a novel method for treating CRSwNP, it is still necessary to reasonably evaluate which patients might benefit most from biological therapy.
