Reslizumab, an anti-interleukin-5 (IL-5) therapy, effectively reduces exacerbations and improves symptoms in severe eosinophilic asthma. Patient selection based on eosinophil counts enhances treatment efficacy and safety.
Area of Science:
- Immunology
- Pulmonology
- Pharmacology
Background:
- Severe eosinophilic asthma presents a significant unmet medical need.
- Reslizumab targets the interleukin-5 (IL-5) pathway, a key driver of eosinophilic inflammation in asthma.
- Monoclonal antibodies like reslizumab offer a novel therapeutic approach.
Purpose of the Study:
- To review clinical trial data on reslizumab for treating eosinophilic asthma.
- To discuss the role of eosinophils and IL-5 in asthma pathogenesis.
- To evaluate the efficacy and safety of reslizumab.
Main Methods:
- Literature review of clinical trials involving reslizumab.
- Searches conducted on PubMed and ClinicalTrials.gov using relevant keywords.
- Analysis of data regarding asthma exacerbations, symptoms, and pulmonary function.
Main Results:
- Reslizumab demonstrated reductions in asthma exacerbations in Phase IIIb trials.
- The therapy improved asthma-related symptoms and pulmonary function.
- Participant selection based on eosinophil counts improved trial outcomes.
Conclusions:
- Reslizumab and other anti-IL-5 therapies show promise for severe eosinophilic asthma.
- Targeted selection of patients with eosinophilic inflammation is crucial for efficacy.
- While safety is good, long-term data are pending; approval is anticipated.

Leukotriene modifiers work through two distinct mechanisms:
Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...

Antiasthma Drugs: β2-Adrenoceptor Agonists
One class of bronchodilators includes β2-adrenoceptor agonists. These agents target the β2-adrenoceptors located on bronchial smooth muscle cells. By stimulating these receptors, β2-agonists induce...
Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
Antiasthma Drugs: Muscarinic Receptor Antagonists
Antimuscarinic agents compete with ACh for the same binding site on the muscarinic receptors. By binding to these receptors, they inhibit the downstream effects of ACh and block the parasympathetic...
