What side effects are associated with this type of intervention?

Common treatments for asthma, particularly those targeting eosinophilic asthma, include inhaled glucocorticoids, LABAs, LAMAs, and biologics like mepolizumab and omalizumab. Inhaled glucocorticoids can cause oral thrush and hoarseness. LABAs may lead to tremors and palpitations. LAMAs, such as tiotropium, can cause dry mouth and urinary retention. Biologics like mepolizumab and omalizumab are generally well-tolerated but can cause injection site reactions and, rarely, anaphylaxis.

What prior FDA approvals exist?

Several FDA-approved treatments target eosinophilic asthma by reducing eosinophil levels. Mepolizumab, an anti-IL-5 monoclonal antibody, has been approved for severe eosinophilic asthma and has shown efficacy in reducing asthma exacerbations and improving quality of life. Benralizumab, another anti-IL-5 receptor monoclonal antibody, depletes eosinophils and is approved for severe eosinophilic asthma. Dupilumab, an IL-4 receptor alpha antagonist, is also approved for moderate-to-severe asthma with an eosinophilic phenotype. These treatments are similar to dexpramipexole, which is being studied for its potential to reduce eosinophil levels in eosinophilic asthma.

What other types of research exist?

Promising novel alternatives to dexpramipexole for reducing eosinophil levels in asthma patients include benralizumab, an IL-5 receptor antagonist, and omalizumab, an anti-IgE antibody. Both have shown efficacy in managing severe eosinophilic asthma.

Pivotal Trial

Summary

This trial is testing an oral medication called dexpramipexole to help people with a type of asthma that isn't well controlled by their current treatments. The medication works by reducing specific white blood cells that cause inflammation, which may improve breathing and asthma control.

Who is the study for?

This trial is for adolescents and adults aged 12 or older with eosinophilic asthma that isn't well-controlled despite using daily low-dose inhaled corticosteroids and another maintenance medication. Participants should have a certain level of lung function reversibility after bronchodilator use, an eosinophil count within a specified range, and not be pregnant. Smokers or those with other complicating health issues are excluded.

What is being tested?

The study tests the effectiveness of dexpramipexole dihydrochloride as an additional oral treatment to improve lung function, control asthma symptoms, and enhance quality of life in patients with eosinophilic asthma. It's compared against a placebo to assess improvements and side effects.

What are the potential side effects?

While specific side effects for dexpramipexole in this context aren't detailed here, common ones may include digestive discomfort, potential blood disorders like neutropenia (low white blood cell count), liver enzyme changes, heart-related issues such as arrhythmias or QT interval changes on ECGs.

Other Research

Asthma treatments often target the underlying inflammation and bronchoconstriction that characterize the disease. Eosinophils, a type of white blood cell, play a significant role in the inflammation seen in eosinophilic asthma. Dexpramipexole, an investigational drug, aims to reduce eosinophil levels, thereby decreasing inflammation and improving lung function. Other common treatments include inhaled corticosteroids (ICS) that reduce overall airway inflammation, long-acting beta-agonists (LABAs) that relax bronchial muscles to improve airflow, and leukotriene receptor antagonists like montelukast that block inflammatory pathways. These treatments are crucial for asthma patients as they help control symptoms, prevent exacerbations, and improve quality of life.
