Biologics are unique in that they target a specific antibody, molecule, or cell involved in asthma.
How to control asthma?
For many patients with asthma, their asthma is controlled by identifying and avoiding triggers, taking a daily inhaled or oral controller medication, and using a quick-relief inhaler when symptoms develop. For some patients though, these medications are not enough to control their asthma.
What are the targets of asthma?
For asthma, the targets are antibodies, inflammatory molecules, or cell receptors. By targeting these molecules, biologics work to disrupt the pathways that lead to inflammation that causes asthma symptoms.

How do eosinophils work?
They work by triggering inflammation in your body. Eosinophils are helpful in preventing disease. However, when there are too many of them, they can cause too much inflammation and swelling. If that swelling is in the airways of your lungs, it can be hard to breathe.
Is Benralizumab approved for asthma?
It was approved by the FDA for severe asthma with an eosinophilic phenotype in 2015. Examples of eosinophilic phenotypes include eosinophilic asthma and Churg Strauss Syndrome. It’s administered as a subcutaneous injection once a month in your upper arm, thigh, or abdomen. 10. Benralizumab (Fesenra).
What is the immune response to asthma?
Asthma is an abnormal immune response. During this response, immune cells recognize harmless proteins you inhale as harmful. One example of a harmless protein is allergens, like dust mites. Many asthma subgroups are regulated by a type of white blood cell (leucocyte) called T-helper 2 (Th2) cells.
Can eosinophils cause asthma?
Eosinophilic inflammation is usually more severe and difficult to control. 3 Normally, eosinophil levels rise during asthma attacks and decline after. But, in some with severe asthma, they may stay elevated. In this way, they may be responsible for severe asthma. So, biologics block the effects of these chemicals.
How often do you need to inject biologics?
This must be done by a medical professional such as a nurse. This must occur 2-3 times a month, depending on the biologic used. And, unfortunately, due to the complex nature of making them, biologics tend to be very expensive. Still, they are neat options when needed.

They also must be stored in solutions in vials. So, they must be given by subcutaneous injections, or just under the surface of the skin.
Does Benralizumab help with asthma?
Similar to the other anti–IL-5 biologics, benralizumab has been shown to reduce asthma exacerbation rates and improve lung function in patients with uncontrolled eos inophilic asthma ( 52 – 54 ). A 2017 Cochrane review demonstrated a significant reduction in asthma exacerbations in patients treated with benralizumab regardless of their AEC. However, the effect of benralizumab was greatest in patients with AEC greater than or equal to 300 cells/μl. Furthermore, improvements in lung function and QOL were only significant in the higher eosinophil group ( 51 ). In the ZONDA trial, benralizumab was shown to significantly reduce OCS use by 75% in patients on long-term OCS with AEC greater than or equal to 150 cells/μl, while reducing annualized asthma exacerbations by 70% ( 55) ( Figure 5 ). Benralizumab appears to be equally effective independent of atopy ( 56 ).

Does asthma affect quality of life?
Specifically, patients with severe asthma have increased hospitalizations, detrimental side effects of oral corticosteroids (OCS), poor quality of life (QOL), and impaired lifestyle as compared with patients with well-controlled disease ( 5 ).
What is T2 low asthma?
T2-low asthma, which includes neutrophilic, mixed, or paucigranulocytic asthma, has a comparatively poorly understood pathophysiology and may be influenced by the concomitant use of corticosteroids suppressing underlying eosinophilia. T2-low asthma is caused by neutrophilic or paucigranulocytic inflammation that results in activation of both T1 and T17 cells, and high IL-17A mRNA levels have been found in patients with moderate to severe asthma ( 15 ). These patients are generally less responsive to corticosteroids, have fewer allergic symptoms, and are older at the time of diagnosis. Currently, there is no approved biologic for T2-low asthma, and thus therapy in this group relies on standard treatment with controller medications and possible bronchial thermoplasty ( 14 ). However, one recent trial suggests macrolide therapy with azithromycin may have a role in reducing exacerbations in patients with T2-low asthma ( 16 ).
Is mepolizumab approved for asthma?
Mepolizumab is currently approved for patients 12 years of age and older with severe asthma with an eosinophilic phenotype. Although the FDA has not set an AEC required for use, RCTs have suggested a benefit for patients with a count as low as 150 cells/μl, particularly in patients on chronic OCS ( 45 ).
What is T2 inflammation?
T2 inflammation occurs in approximately half of patients with asthma and may be slightly more common in patients with severe asthma ( 11 ). In T2-high asthma, inhaled allergens, microbes, and pollutants interact with the airway epithelium, which subsequently leads to activation of mediators such as thymic stromal lymphopoietin (TSLP), IL-25, and IL-33 ( Figure 1 ). This process leads to activation of IL-4, IL-5, and IL-13, which can result in attraction and activation of basophils, eosinophils, and mast cells; secretion of IgE by B cells; and activation of innate cells such as the airway epithelium and smooth muscle, resulting in bronchoconstriction, airway hyperresponsiveness, mucus production, and airway remodeling ( 12, 13 ). T2-high asthma encompasses both allergic and nonallergic eosinophilic asthma. Although an allergen-specific, IgE-dependent process plays a significant role in allergic asthma, T2 cytokines play a dominant role in inflammation in nonallergic eosinophilic asthma. Sputum and blood absolute eosinophil counts (AECs), serum IgE, exhaled nitric oxide, and serum periostin are all important biomarkers of T2 inflammation that can help predict response to biologics ( 14 ).
