A large clinical trial has brought us one step closer to finding a safer and more effective relief for people suffering from severe asthma. The trial revealed that a monoclonal antibody treatment called benralizumab can significantly reduce the need for high-dose steroid treatments, which are known to carry a multitude of risks and side effects. This breakthrough could provide hope for the approximately 5 percent of asthma patients worldwide who have a severe form of this respiratory disease.
Living with severe asthma is a daily battle for almost 300 million people worldwide. These individuals face the terrifying challenge of struggling to breathe properly on a constant basis. The symptoms of severe asthma, including chest tightness, coughing, and panic, can be overwhelming and debilitating. Consequently, these patients often find themselves making frequent visits to the hospital in search of relief.
To control their severe asthma, patients rely on high doses of steroids, which work by reducing inflammation in the body and decreasing the production of mucus in the lungs. However, these high levels of steroids come with a range of risks and side effects. Increased diabetes, fractures, cataracts, and suppression of the adrenal system are just a few examples of the dangers associated with these medications. Moreover, the effectiveness of high-dose steroids in treating severe asthma is a topic of ongoing debate. Lower doses have shown to have a proportionally larger impact, but unfortunately, patients often have no choice but to resort to higher doses when lower ones fail.
The treatment at the center of the clinical trial, benralizumab, offers a more targeted solution to severe asthma. This protein antibody works by reducing the number of eosinophils, inflammation-causing immune cells that are produced in excessive amounts in severe asthma cases. The trial, conducted across Europe with over 200 patients, yielded remarkable results. An astounding 92 percent of participants were able to safely reduce their use of inhaled steroids, with over 60 percent no longer requiring them at all. Furthermore, nearly 90 percent of patients in the steroid reduction group remained free of exacerbations throughout the trial period.
While the results of the clinical trial are highly promising, experts caution that they only apply to a very specific type of asthma known as severe eosinophilic asthma. Patients who do not respond as well to benralizumab may still require intensive steroid treatments. It is important to note that the risks associated with high doses of steroids have prompted the Global Initiative for Asthma to recommend lowering the dosage in patients responding well to immune therapies. This recommendation is supported by the research conducted on benralizumab. However, it is crucial to understand that the results may not be replicated across all similar treatments.
The findings of this clinical trial offer a glimpse of hope for individuals suffering from severe asthma. The success of benralizumab in reducing the dependence on high-dose steroids demonstrates the potential of targeted antibody treatments in managing this debilitating condition. While further research is needed to validate these results and explore potential variations in treatment response, the discovery of new approaches like benralizumab marks a significant milestone towards a safer and more effective relief for those living with severe asthma.
