Emerging Therapies for Bronchial Asthma


Asthma, particularly bronchial asthma, continues to be a significant health concern globally. According to the World Health Organization, approximately 339 million people worldwide are affected by asthma. Despite significant improvements in asthma management over the years, many patients continue to suffer from suboptimal control of the disease, leading to frequent exacerbations, disrupted sleep patterns, decreased work productivity, and reduced overall quality of life. As a result, there is a persistent need for novel and more effective therapeutic options.

The State of Current Therapies

Current therapies for bronchial asthma primarily focus on reducing inflammation, managing symptoms, and preventing exacerbations. These therapies often include the use of inhaled corticosteroids (ICS), long-acting beta2-agonists (LABA), short-acting beta2-agonists (SABA), leukotriene modifiers, theophylline, and oral corticosteroids. Despite these options, some patients continue to experience regular asthma symptoms and frequent exacerbations.

Emerging Therapies

Several emerging therapies appear promising for better management of bronchial asthma. These potential treatments range from new pharmacologic agents to various immunotherapies and gene therapies.

Biologics: Biologics are a recent breakthrough, customized to target specific elements of the immune system responsible for the inflammatory response in asthma. These include monoclonal antibodies like omalizumab, mepolizumab, and reslizumab that target immunoglobulin E (IgE), interleukin-5 (IL-5), and IL-5 receptor, respectively. These drugs have shown considerable success in severe asthma and could potentially revolutionize asthma treatment.

Bronchial thermoplasty: This is a non-pharmacological intervention involving the deliverance of thermal energy to the airway wall during bronchoscopy. It is designed to reduce bronchial hyperreactivity by reducing the amount of airway smooth muscle. Trials have demonstrated that bronchial thermoplasty leads to reductions in asthma exacerbations, emergency room visits, and hospitalizations for respiratory symptoms.

Gene therapy: Gene therapy has shown immense potential in addressing various diseases at their genetic base, including asthma. Early studies involve genes associated with inflammatory cytokines and remodeling enzymes, although there is a long way to go before gene therapy can become a feasible therapeutic option.


The emergence of new therapies offers exciting prospects for advancing bronchial asthma control. As science progresses, the optimum management of bronchial asthma will likely change and become increasingly personalized to individual sufferers’ needs. Despite considerable strides, there is still much work to be done, not just in the development of new therapies but also in understanding the complex genetic and environmental interactions that underlie the pathophysiology of asthma. As we continue to explore and understand the depths of this disease, further advancements in therapeutic interventions are bound to follow.

Frequently Asked Questions

  1. What are biologics and how do they help in asthma?
    Biologics are medication made from living organisms. They target specific components of the immune system that are involved in the inflammatory process of asthma, reducing inflammation and subsequent asthma symptoms.

  2. What is bronchial thermoplasty?
    Bronchial thermoplasty is a non-drug procedure where heat is used to shrink the smooth muscles in the airways, reducing their ability to constrict and trigger an asthma attack.

  3. How does gene therapy work for asthma?
    Gene therapy aims at modifying or inserting genes into a patient’s cells to treat or prevent disease. In asthma, it still in experimental stages, with the focus on genes associated with inflammatory and remodeling processes in the lungs.

  4. Are these emerging therapies available for everyone with asthma?
    These therapies are considered for individuals with severe asthma that’s difficult to control with standard treatments. However, their accessibility may vary, and they may not be suitable or approved for everyone. Please consult a healthcare professional for personalized advice.

  5. Can these new treatments cure asthma?
    While these emerging therapies aim to better control asthma symptoms and improve the quality of life, asthma is currently incurable. These treatments focus on reducing the frequency and severity of asthma attacks rather than curing the disease.
