Review

Author: Bobolea, Irina ; Barranco, Pilar ; Domínguez-Ortega, Javier ; Quirce, Santiago

Despite the administration of appropriate treatment, a high number of patients with asthma remain uncontrolled. This suggests the need for alternative treatments that are effective, safe and selective for the established asthma phenotypes, especially in patients with uncontrolled severe asthma. The most promising options among the new asthma treatments in development are biological therapies, particularly those monoclonal antibodies directed at selective targets. It should be noted that the different drugs, and especially the new biologics, act on very specific pathogenic pathways. Therefore, determination of the individual profile of predominant pathophysiological alterations of each patient will be increasingly important for prescribing the most appropriate treatment in each case. The treatment of severe allergic asthma with anti-IgE monoclonal antibody (omalizumab) has been shown to be effective in a large number of patients, and new anti-IgE antibodies with improved pharmacodynamic properties are being investigated. Among developing therapies, biologics designed to block certain pro-inflammatory cytokines, such as IL-5 (mepolizumab) and IL-13 (lebrikizumab), have a greater chance of being used in the clinic. Perhaps blocking more than one cytokine pathway (such as IL-4 and IL-13 with dulipumab) might confer increased efficacy of treatment, along with acceptable safety. Stratification of asthma based on the predominant pathogenic mechanisms of each patient (phenoendotypes) is slowly, but probably irreversibly, emerging as a tailored medical approach to asthma, and is becoming a key factor in the development of drugs for this complex respiratory syndrome.

No Effect of Anti-Interleukin-5 Therapy (Mepolizumab) on the Atopy Patch Test in Atopic Dermatitis Patients

Q3 · MEDICINE

Article

Author: Bihari, I. C. ; Laifaoui, J. ; Kapp, A. ; Ploetz, S. ; Knol, E. F. ; Bruijnzeel-Koomen, C. A. F. M. ; Katzer, K. ; Darsow, U. ; Werfel, T. ; Ring, J. ; Oldhoff, J. M. ; de Bruin-Weller, M. S.

Background: The atopy patch test (APT) is an in vivo model to study the induction of eczema by inhalant allergens in atopic dermatitis (AD) patients. Mepolizumab is a monoclonal antibody to interleukin-5, which reduces peripheral blood eosinophils. Previously, we reported that mepolizumab treatment did not result in clinical improvement in AD. The current study investigates the effect of mepolizumab therapy on the APT in the same patients. Methods: Mepolizumab treatment was given at days 0 and 7 in a double-blind placebo-controlled design. The APT was applied at days –2, 0, 14 and 28. Clinical evaluation of each APT was conducted 48 h after application at days 0, 2, 16 and 30. Skin biopsies were taken at days 0, 2 and 16 for eosinophil counts. Results: The mepolizumab-treated group showed no significant reduction in macroscopic outcome of the APT. Tissue eosinophils were reduced in the mepolizumab-treated group at day 16 compared with placebo; however, this was not significant. Conclusion: Mepolizumab therapy cannot prevent the eczematous reaction induced by the APT. Furthermore, the influx of tissue eosinophil numbers in the APT is not significantly inhibited after mepolizumab treatment compared with placebo, despite a significant reduction in peripheral blood eosinophils.

Article

Author: Dong, Qingfeng ; Li, Cuiyun ; Li, Xiaojiao ; Sun, Yu ; Sun, Jixuan ; Wu, Min ; Liu, Zhijie ; Xu, Jia ; Ding, Yanhua

Objective:

To evaluate the similarity of BAT2606 and mepolizumab, including pharmacokinetic profiles, immunogenicity, and safety, in healthy Chinese men.

Methods:

This randomized, double-blind, parallel three-arm, single-dose Phase I clinical study enrolled 207 subjects. All subjects enrolled in this study were randomly assigned to receive BAT2606 or mepolizumab (European-sourced Nucala [Nucala-EU] and US-sourced Nucala [Nucala-US]) at a 1:1:1 ratio. In total, 206 subjects received a subcutaneous injection of 100 mg of one of the drugs in this study.

Results:

The mean drug concentration–time curves were similar among the three groups. The 90% confidence intervals of the geometric mean ratios of maximum concentration and area under the curve from time 0 to infinity were within 80.00%–125.00%. There were no adverse events leading to study discontinuation or death, no serious adverse events, and no local injection-site reactions. The rates of adverse events and treatment-related adverse events were comparable among the BAT2606 (78.3% and 66.7%, respectively), Nucala-US (76.5% and 64.7%, respectively), and Nucala-EU groups (82.6% and 71.0%, respectively). The majority of treatment-related adverse events were grade 1 or 2 in severity based on Common Terminology Criteria for Adverse Events version 5.0. Anti-drug antibodies (ADAs) were detected in 4 (5.8%), 10 (14.7%), and 10 subjects (14.5%) in the BAT2606, Nucala-US, and Nucala-EU groups, respectively. All subjects with a positive ADA result were negative for neutralizing antibodies.

Conclusion:

BAT2606 injection was pharmacokinetically bioequivalent to Nucala-US and Nucala-EU in healthy Chinese men. BAT2606 was well tolerated, and its overall safety profile was similar to those of Nucala-US and Nucala-EU. BAT2606 had a numerically lower ADA incidence than Nucala-US and Nucala-EU.

Severe Asthma Overview Severe asthma is a chronic respiratory condition characterized by persistent symptoms that are difficult to control, even with high-dose medications. Unlike milder forms of asthma, severe asthma can significantly impair the quality of life and may result in frequent exacerbations requiring hospitalization. The exact cause of severe asthma is not entirely clear, but it often arises from a combination of genetic and environmental factors. These may include respiratory infections, allergens (pollen, mold, dust mites), pollutants (tobacco smoke, air pollution), occupational irritants, and lifestyle factors such as obesity and stress. Severe asthma can also develop in people whose milder asthma is not well-controlled over time. Diagnosis of severe asthma begins with a comprehensive medical history, physical examination, and pulmonary function tests like spirometry to assess lung function. Doctors may also order additional tests, such as chest X-rays, blood tests, and allergy tests to identify triggers. A key factor in diagnosing severe asthma is the persistence of symptoms despite the optimal use of standard asthma treatments. Managing severe asthma typically requires a multifaceted approach. Inhaled corticosteroids and long-acting bronchodilators are the mainstays of treatment. For those who do not respond to these medications, biologic therapies (such as omalizumab, mepolizumab, or dupilumab) may be prescribed to target specific pathways involved in the inflammatory response. In addition, patients with severe asthma may benefit from lifestyle modifications, including weight management, avoiding triggers, and pulmonary rehabilitation. In extreme cases, systemic corticosteroids may be necessary, although long-term use can have serious side effects.
