Trial Summary

What is the purpose of this trial?

This trial tests CXA-10, a synthetic compound that reduces inflammation, in obese adults with asthma. The goal is to see if it can help control asthma symptoms by calming down the body's immune response.

Will I have to stop taking my current medications?

The trial requires that you continue taking your regular asthma medications, such as inhaled corticosteroids, long-acting beta agonists, and long-acting muscarinic antagonists, as long as you have been on a stable dose for at least 4 weeks before starting the study.

What evidence supports the effectiveness of the drug CXA-10 for treating asthma?

Research shows that a similar compound, 10-nitro-oleic acid, reduced the severity of allergic airway disease in mice, suggesting it may help with asthma. This compound works by reducing inflammation and promoting the removal of certain immune cells, which could be beneficial for severe asthma that doesn't respond well to standard treatments. ^{1 2 3 4 5}

Is CXA-10 safe for humans?

In studies with healthy and obese people, CXA-10 was generally safe and well-tolerated, with the most common side effects being diarrhea, abdominal pain, and nausea. No serious health issues were found during physical exams or lab tests. ^{1 5 6 7 8}

How is the drug CXA-10 different from other asthma treatments?

CXA-10 is unique because it is an anti-inflammatory lipid mediator that works by promoting the resolution of inflammation, unlike traditional asthma treatments that mainly focus on blocking inflammation. This drug is part of a new class of compounds that have shown potential in reducing airway inflammation and hyper-responsiveness in asthma. ^{1 2 4 9 10}

Findings from Research

Individuals with severe asthma have significantly lower levels of Lipoxin A(4) (LXA(4)), a mediator that helps resolve inflammation, compared to those with nonsevere asthma, suggesting a potential deficiency in anti-inflammatory mechanisms.

The study found decreased expression of lipoxin biosynthetic enzymes and receptors in severe asthma, indicating that the inability to produce and respond to lipoxins may contribute to the persistent airway inflammation seen in these patients.

A new class of lipid mediators, including lipoxins, resolvins, protectins, and maresins, derived from polyunsaturated fatty acids, shows strong anti-inflammatory effects in both laboratory and animal studies.

These compounds have significant therapeutic potential for treating various inflammatory lung diseases, such as asthma, cystic fibrosis, and acute lung injury, addressing a critical need for effective anti-inflammatory treatments.

Lipoxins (LXs) are important anti-inflammatory mediators derived from arachidonic acid metabolism, playing a crucial role in resolving inflammation in asthma, with their levels influenced by bronchial inflammation and glucocorticoid treatments.

Mild asthmatics have higher levels of lipoxin synthesis compared to severe asthmatics, suggesting that enhancing LX production in severe cases could be a potential therapeutic strategy for improving bronchial inflammation resolution.

The review highlights the role of polyunsaturated fatty acids (PUFAs) and their metabolites, such as eicosanoids and specialized pro-resolving lipid mediators (SPMs), in the chronic inflammation and bronchial obstruction associated with asthma.

Recent advances in lipidomics suggest that SPMs could be potential therapeutic agents for managing asthma by promoting the resolution of inflammation, offering a new avenue for treatment.

Nitrated fatty acids (NFAs), specifically 10-nitro-oleic acid (OA-NO2), have shown promise as an effective treatment for allergic airway disease in preclinical models, reducing disease severity and demonstrating unique mechanisms of action compared to traditional inhaled steroids.

Unlike fluticasone, which is a common inhaled steroid, OA-NO2 not only reduced inflammation but also induced apoptosis of neutrophils, suggesting it may be particularly beneficial for patients with severe asthma that is resistant to steroid treatment.

CXA-10, a novel nitro fatty acid, has shown promise in reducing biomarkers of inflammation and metabolic stress in healthy and obese subjects, indicating its potential therapeutic effects in conditions related to oxidative stress.

The compound was found to be safe and well-tolerated, with dose-related adverse events primarily including diarrhea, abdominal pain, and nausea, and no significant clinical abnormalities reported, paving the way for ongoing Phase II studies in patients with specific diseases.

Patients with severe asthma, whether they have aspirin-exacerbated respiratory disease (AERD) or not, show significantly lower levels of the anti-inflammatory molecule lipoxin A4 (LX A4), indicating a potential link between asthma severity and LX metabolism.

The study suggests that lower LX A4 levels in severe asthma patients could open up new treatment possibilities using LX analogues, as these patients may benefit from therapies that enhance LX A4 production.

CRBM-0244, a new derivative of docosahexaenoic acid (DHA), effectively prevents bronchial hyperresponsiveness and reduces inflammation in both human bronchi and a guinea pig model of allergic asthma, indicating its potential as a therapeutic agent for asthma.

The mechanism of action involves the inhibition of NF-κB activation and COX-2 overexpression, along with a reduction in Ca(2+) sensitivity of bronchial smooth muscle, suggesting that CRBM-0244 modulates inflammatory responses through specific biochemical pathways.

Lipoxins, a type of eicosanoid, have unique anti-inflammatory properties that can significantly reduce airway hyperresponsiveness and inflammation in asthma, as shown in experimental models.

The administration of a stable analog of lipoxin A(4) not only decreased inflammation but also indicated that targeting lipoxin pathways could offer new therapeutic strategies for managing asthma and airway inflammation.

Lipoxin A4 (LXA4) stable analogs, specifically ATLa and ZK-994, effectively reduced inflammation in allergen-driven models by preventing excessive accumulation and activation of immune cells like eosinophils and T lymphocytes, showing over 50% reduction in leukocyte trafficking at doses below 0.5 mg/kg.

Unlike the CysLT1 receptor antagonist montelukast, LXA4 analogs not only reduced inflammatory cytokines such as IL-4 and IL-13 but also demonstrated a unique mechanism of action, highlighting their potential as new therapeutic agents for managing allergic airway inflammation and hyper-responsiveness.
