Abstract
Severe asthma is a complex and heterogeneous chronic airway inflammatory disease. Current treatment strategies are increasingly focused on disease classification, facilitating the transition towards personalized medicine by integrating biomarkers and monoclonal antibodies for tailored therapeutic approaches. Several approved biological agents, including anti-immunoglobulin E (IgE), anti-interleukin (IL)-4, anti-IL-5, and anti-thymic stromal lymphopoietin (TSLP) monoclonal antibodies, have demonstrated significant efficacy in reducing asthma exacerbations, eosinophil counts, improving lung function, minimizing oral corticosteroid usage, and enhancing patients' quality of life. The utilization of these biological agents has brought about profound transformations in the management of severe asthma. This article provides a comprehensive review on biomarkers and biological agents for severe asthma while emphasizing the increasing importance of further research into its pathogenesis and novel treatment modalities.

Kroes JA, Van Hal LHG, Van Dijk L, Zielhuis SW, Van Der Meer AN, Van Roon EN, Ten Brinke A. The perceived waning of biologics in severe asthma. Respir Med 2023; 219:107416. [PMID: 37757988 DOI: 10.1016/j.rmed.2023.107416] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/07/2023] [Revised: 08/21/2023] [Accepted: 09/18/2023] [Indexed: 09/29/2023]
Abstract
BACKGROUND Biologics are highly effective in severe asthma and used at fixed dosing intervals. However, in clinical practice, dosing intervals are sometimes shortened if patients perceive a decreased biologic effect before the next administration. The occurrence and clinical relevance of this perceived waning of biological effect is unknown. OBJECTIVE To explore (1) the frequency, severity and conditions, (2) associated symptoms and (3) relationship with clinical characteristics of the patient-perceived waning effect of biologics before the next administration. METHODS Severe asthma patients receiving biological treatment ≥4 months were included. Based on 17 semi-structured patient interviews, we developed a questionnaire focusing on the waning effect of biologics before the next administration, which was distributed among 129 patients. Clinical characteristics, including asthma control (ACQ) and quality of life (AQLQ) scores, were collected from patient files. RESULTS 65/101 patients who completed the questionnaire reported a waning of biological effect, graded as severe (median (IQR) 6.5 (5-7.5) on a 0-10 BORG-scale). Waning manifested in a broad spectrum of symptoms. Patients reporting waning had higher ACQ and lower AQLQ scores versus those without (p < 0.05) and higher BORG-scores were associated with higher exacerbation rate (ρ = 0.309, p = 0.013). A third of all patients were in favor of extending or shortening their dosing interval. CONCLUSION Two-thirds of severe asthma patients report waning of biologic effect at the end of the dosing interval, which is associated with poorer asthma control and quality of life. The diversity in observed waning of effect opens the way for research into more individualized dosing of biologics.

Evidence-Based Approach of Biologic Therapy in Bronchial Asthma. J Clin Med 2023; 12:4321.

Abstract
The emergence of biologic agents in the treatment of bronchial asthma has a wide impact on improving quality of life, reducing morbidity, and overall health care utilization. These therapies usually work by targeting specific inflammatory pathways involving type 2 inflammation and are particularly effective in severe eosinophilic asthma. Various randomized controlled trials have shown their effectiveness by reducing exacerbation rates and decreasing required glucocorticoid dosages. One of the relatively newer agents, tezepelumab, targets thymic stromal lymphoprotein and has proven its efficacy in patients independent of asthma phenotype and serum biomarker levels. This article reviews the pathophysiologic mechanism behind biologic therapy and offers an evidence-based discussion related to the indication, benefits, and adverse effects of such therapies.

Perceptions on Home-Administration of Biologics in the Context of Severe Asthma: An International Qualitative Study. THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY. IN PRACTICE 2022; 10:2312-2323.e2. [PMID: 35487370 DOI: 10.1016/j.jaip.2022.04.015] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/21/2021] [Revised: 04/05/2022] [Accepted: 04/11/2022] [Indexed: 06/14/2023]
Abstract
BACKGROUND Biologics are an effective therapy for severe asthma. Home administration of biologics by patients is likely to facilitate their accessibility. Yet little is known about patients' and health care providers' (HCPs) perceptions regarding home administration of biologics. OBJECTIVE The aim of this study is to create more insight into the perceptions and experiences of patients and HCPs regarding home administration of biologics in the context of the treatment of severe asthma. METHODS A qualitative international study was performed in the Netherlands, United States, Australia, and United Kingdom. In each country, 2 focus groups were held with potential/recent and long-term users of biologics at home. Prior to the focus groups, patients were prompted with themes on online forums. For triangulation purposes, interviews were held with HCPs to discuss salient findings from forums and focus groups. Data were analyzed with qualitative content analysis. RESULTS In total, 75 patients participated in the forums, of which 40 participated in the focus groups. Furthermore, 12 HCPs were interviewed. The following overarching themes were identified: living with severe asthma; practical aspects of using biologics; the role of HCPs regarding biologics; social support from family, friends, and others; effectiveness of biologics and other treatments; side effects of biologics. CONCLUSIONS This study showed that, for those using biologics for severe asthma, the benefits of home administration of biologics usually outweigh inconvenience and side effects. Guided practice, accessible support contact, and monitoring including social support should be central in the transition from hospital to home administration of asthma biologics.

[PMID: 34760031 PMCID: PMC8575614 DOI: 10.1155/2021/7456208] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2021] [Accepted: 10/13/2021] [Indexed: 11/17/2022] Open
Abstract
Background The population of uncontrolled asthma patients represents a large therapeutic burden. The PDE3-inhibitor enoximone is a strong and quick bronchodilator and is known to successfully treat life-threatening bronchial asthma (status asthmaticus). Translational mice models showed anti-inflammatory effects when PDE3 was targeted. Methods Here, we investigated the effectiveness of PDE3-inhibitor enoximone as oral treatment for chronic asthma in a real-life off-label setting. Investigational use of PDE3-inhibitor enoximone: 51 outpatients (age 18-77) with chronic asthma were followed using off-label personalized low doses of the PDE3-inhibitor enoximone. Duration of treatment was 2-8 years. Results Four groups could be distinguished as follows: The first group includes patients who use enoximone as an add-on, because it helps them in maintaining a better general wellbeing; they still use their traditional medication (n = 5). The second group consists of patients who use enoximone and were able to phase down their traditional medication without deterioration of their asthma symptoms (n = 11). The third group comprises patients who were able to discontinue their traditional medication and use only enoximone without deterioration of their asthma symptoms (n = 24). The last one has patients who, after having used enoximone for some time, saw their symptoms disappear and now use no medication at all, not even enoximone (n = 11). All patients reported improvement or at least alleviation of their asthma symptoms. All patients reported a better quality of life and greater drug compliance. Conclusion The evaluation shows that PDE3-inhibitor enoximone is a viable alternative for or addition to current asthma therapeutics, as both add-on and stand-alone, considerably reducing the use of LABAs/SABAs/ICS, with no or negligible side effects. Additional studies are advisable.
