What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores a new treatment, Atuliflapon, for individuals with moderate to severe asthma not well controlled by current medications. The study compares the effects of Atuliflapon to a placebo (a substance with no active medication) to determine if it improves asthma symptoms over 12 weeks. Participants must have had asthma for at least a year and experienced at least one severe asthma attack in the past year. As a Phase 2 trial, this research focuses on measuring the treatment's effectiveness in an initial, smaller group of people.

Will I have to stop taking my current medications?

The trial requires that you stay on a stable dose of your current asthma medications, such as inhaled corticosteroids and long-acting β2-agonists, for at least 3 months before starting. However, certain medications like systemic corticosteroids, leukotriene receptor antagonists, and some biologics must be stopped for a specified period before joining the trial.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that Atuliflapon is usually well-tolerated by adults with moderate to severe uncontrolled asthma. Studies found that people taking Atuliflapon did not experience more serious side effects than those taking a placebo. Some participants reported mild side effects like headaches or nausea, but these were uncommon. It is important to note that this treatment remains under study, and ongoing research will provide more information about its safety. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for asthma?

Unlike the standard asthma treatments, which often focus on reducing inflammation with corticosteroids or relaxing airways with bronchodilators, Atuliflapon targets a different pathway. It inhibits the enzyme FLAP (5-lipoxygenase activating protein), which plays a key role in the production of leukotrienes, compounds that drive inflammation and bronchoconstriction in asthma. Researchers are excited about Atuliflapon because by tackling this alternative pathway, it has the potential to help patients who don't respond well to existing therapies. This could mean better control of asthma symptoms and fewer flare-ups for those with uncontrolled asthma.

What evidence suggests that this trial's treatments could be effective for uncontrolled asthma?

Research has shown that Atuliflapon is under study for its potential to improve symptoms in people with moderate to severe asthma that isn't well-controlled. Early results suggest that taking Atuliflapon once a day might be beneficial. This trial compares Atuliflapon to a placebo to evaluate its effectiveness. Although human trial data remains limited, researchers are exploring the potential benefits of the investigational treatment Atuliflapon. ^{1 2 3 4 5}

Trial Overview The trial is testing Atuliflapon's effectiveness and safety compared to a placebo over 12 weeks in adults with uncontrolled asthma. It's randomized (participants are assigned by chance), double-blind (neither participants nor researchers know who gets what treatment) and placebo-controlled (compared against an inactive substance).

How Is the Trial Designed?

Group I: Part 1 (Atuliflapon) Experimental Treatment 1 Intervention

Randomised participants will receive Atuliflapon in Part 1 of the study.

Group II: Lead-in PK cohort (Atuliflapon) Experimental Treatment 1 Intervention

Randomised participants will receive Atuliflapon in Lead-in PK period of the study.

Group III: Lead-in PK cohort (Placebo) Placebo Group 1 Intervention

Randomised participants will receive matching placebo to Atuliflapon in Lead-in PK cohort of the study.

Group IV: Part 1 (Placebo) Placebo Group 1 Intervention

Randomised participants will receive matching placebo to Atuliflapon in Part 1 of the study.

Published Research Related to This Trial

Zafirlukast, when added to standard asthma treatment, showed improvements in pulmonary function and quality of life in patients with stable asthma, with significant increases in morning and evening peak expiratory flow (PEF) values.

In patients experiencing an asthma attack, zafirlukast combined with a reduced dose of glucocorticoids led to better pulmonary function outcomes compared to standard treatment alone, although the differences were not statistically significant.

A comprehensive analysis of 3,234 asthma drug-related articles from 1982 to 2021 revealed that the United States leads in research output, with the Karolinska Institute in Sweden being the most active institution, indicating a strong global interest in asthma treatment advancements.

Current research hotspots include optimizing existing asthma medications and developing new monoclonal antibodies like omalizumab and mepolizumab, which aim to improve asthma control and safety, particularly for severe asthma cases.

Antileukotrienes, including montelukast and zafirlukast, are effective in treating chronic asthma and have shown particular efficacy in exercise-induced asthma, with montelukast being the most studied in children.

All antileukotrienes are generally well tolerated, but zileuton may pose a risk for liver-related side effects; the occurrence of Churg-Strauss syndrome in patients is more likely linked to corticosteroid withdrawal rather than the antileukotrienes themselves.

Leukotriene receptor antagonists (like zafirlukast and montelukast) are effective in treating asthma, significantly improving symptoms, pulmonary function, and reducing the need for other medications, with a 50% reduction in asthma exacerbations compared to placebo.

These medications are well tolerated, have a similar side effect profile to placebo, and their use can lead to over a 50% reduction in healthcare costs associated with asthma management, making them a valuable option for patients with persistent asthma.

In the phase 2b PATHWAY study involving 550 adults with severe, uncontrolled asthma, tezepelumab significantly reduced asthma exacerbations by up to 71% and improved lung function and quality of life compared to placebo.

Tezepelumab treatment led to higher rates of patient-reported outcomes, with up to 82% of patients showing improved asthma control and quality of life, indicating its effectiveness in managing severe asthma symptoms.

Tezepelumab has shown significant efficacy in treating severe, uncontrolled asthma, as demonstrated in a pooled analysis of the PATHWAY and NAVIGATOR clinical trials, which included a diverse group of participants.

The results indicate that tezepelumab effectively reduces asthma exacerbations and improves lung function, making it a promising treatment option for patients with difficult-to-control asthma.

In a study of 53 patients with persistent allergic rhinitis, the combination treatment MP-AzeFlu significantly reduced symptom severity, with a visual analogue scale score dropping from 73.4 mm at baseline to 28.1 mm by day 42, indicating rapid and sustained relief.

Endoscopic evaluations showed substantial improvements in nasal mucosa, with severe edema decreasing from 53.1% to 3.8% and thick discharge from 28.3% to 4.8% after 28 days, confirming the safety and effectiveness of MP-AzeFlu in a real-world setting.
