What side effects are associated with this type of intervention?

Common treatments for severe eosinophilic asthma, such as mepolizumab, benralizumab, dupilumab, and reslizumab, primarily target eosinophil levels and inflammation. Known side effects of these treatments include injection site reactions, headache, back pain, fatigue, and oropharyngeal pain. Some patients may experience more serious reactions such as hypersensitivity or anaphylaxis, although these are rare. Monitoring for these side effects is essential to ensure patient safety.

What prior FDA approvals exist?

Several drugs targeting eosinophilic inflammation in asthma have received FDA approval. Mepolizumab, an anti-IL-5 monoclonal antibody, reduces eosinophil levels and has been approved for severe eosinophilic asthma. Other similar biologics include benralizumab and reslizumab, which also target IL-5 to reduce eosinophil counts and inflammation. Dupilumab, targeting the IL-4 receptor alpha, is approved for moderate-to-severe asthma and helps reduce inflammation by inhibiting IL-4 and IL-13 signaling. These treatments aim to control severe asthma by addressing the underlying eosinophilic inflammation.

What other types of research exist?

Pivotal Trial

Summary

This trial is testing a medication called dexpramipexole to see if it can help people with severe eosinophilic asthma that isn't well-controlled by current treatments. The medication works by lowering the levels of certain cells in the blood that cause inflammation. The goal is to find out if this can improve asthma symptoms and be safe for patients.

Who is the study for?

This trial is for adolescents and adults over 12 years old with severe eosinophilic asthma that isn't well-controlled. They should have had at least two asthma attacks in the last year needing steroids, an eosinophil count above a certain level, and not be current smokers or have a heavy smoking history. Women who can get pregnant must use birth control.

What is being tested?

The study tests dexpramipexole's safety and effectiveness against a placebo in managing severe eosinophilic asthma. Participants will randomly receive either the actual drug or a placebo to compare outcomes between the two groups.

What are the potential side effects?

While specific side effects of dexpramipexole are not listed here, common ones may include headache, nausea, potential allergic reactions, or issues related to immune system changes due to its effect on white blood cells.

Mechanism Of Action

Side Effect Profile

Other Research

Asthma treatments work through various mechanisms to reduce inflammation, relax airway muscles, and prevent exacerbations. Inhaled corticosteroids (ICS) reduce airway inflammation and swelling, making it easier to breathe. Long-acting beta agonists (LABAs) relax the muscles around the airways, helping to keep them open. Leukotriene modifiers block chemicals that cause inflammation and bronchoconstriction. Biologics, such as dexpramipexole, target specific pathways involved in asthma, like reducing eosinophil levels and inflammation. These mechanisms are crucial for asthma patients as they help control symptoms, improve lung function, and reduce the frequency and severity of asthma attacks.
