Five monoclonal antibodies—omalizumab, mepolizumab, reslizumab, benralizumab, and dupilumab—are in widespread use, while the recently approved tezepelumab, an anti-thymic stromal lymphopoietin, broadens therapeutic possibilities to encompass the type 2 inflammation‑low phenotype. Although biologics have become more accessible, clinicians frequently encounter difficulties in choosing the most appropriate initial biologic therapy. This review describes real-world cases that demonstrate phenotype-guided selection of biologics for individuals with asthma or eosinophilic granulomatosis with polyangiitis. Additionally, current advances in biologic therapies are examined regarding their capacity to improve both accessibility and clinical efficacy. Moving forward, the integration of emerging evidence with patient‑specific factors could further promote disease modification in the management of severe asthma.  \nKeywords: Asthma; Severe Asthma; Biologics; Personalized Care  \nAddress for correspondence Sang Hyuk Kim  \nDivision of Pulmonary, Allergy, and Critical Care Medicine, Department of Internal Medicine, Korea University Guro Hospital,  \nKorea University College of Medicine, 148 Gurodong-ro, Guro-gu, Seoul 08308, Republic of Korea  \nPhone 82-2-2626-3192  \nFax 82-2-2626-1166  \n[E-mail](E-mail gost702@korea.ac.kr)[ gost702@korea.ac.kr](E-mail gost702@korea.ac.kr)[ ](E-mail gost702@korea.ac.kr)[Received](Received Aug. 1)[ Aug. 1](Received Aug. 1), 2025  \nRevised Sep. 23, 2025  \nAccepted Oct. 13, 2025  \nPublished online Oct. 15, 2025  \nIt is identical to the Creative Commons Attribution NonCommercial License ([http://](http://)[ ](http://)[creativecommons.org/licenses/](creativecommons.org/licenses/)[ ](creativecommons.org/licenses/)[by-nc/4.0/](by-nc/4.0/)) .  \nTuberc Respir Dis 2026;89:1-9 [https://e-trd.org/](https://e-trd.org/ 1)[ 1](https://e-trd.org/ 1)  \nSH Kim  \nIntroduction  \nSevere asthma poses a significant challenge in asthma management, impacting more than 10 million individuals worldwide1. In recent years, biologic therapies have significantly changed the therapeutic landscape for severe asthma2,3 . Clinicians are now able to tailor treatments based on biomarkers, including immunoglobulin E (IgE), blood eosinophil levels, and fractional exhaled nitric oxide (FeNO), which indicate type 2 inflammation (T2) activation4. Until a few years ago, five monoclonal antibodies—omalizumab, mepolizumab, reslizumab, benralizumab, and dupilumab—had received global approval for the management of severe asthma5. More recently, a sixth biologic agent, tezepelumab—an anti-thymic stromal lymphopoietin (TSLP) antibody—has expanded therapeutic options to include patients with T2-low severe asthma6. Nonetheless, there are still considerable unmet needs, such as achieving true disease modification, improving control of oral corticosteroid (OCS)-dependent asthma, and developing effective approaches for indiv","cbCais0xrCHl8pQk","https://ap.wps.com/l/cbCais0xrCHl8pQk","pdf",538575,"English","# Abstract\n# Introduction\n## Case 1\n## Considerations before using a biologic\n## Table 1.
