In a significant medical breakthrough, British researchers have developed the first new treatment for asthma attacks and chronic obstructive pulmonary disease (COPD) in five decades.
This novel approach, involving a single injection, has demonstrated remarkable efficacy, reducing the need for further treatment by 30%. Scientists believe this innovation could be “game-changing” for millions worldwide suffering from these chronic lung conditions.
The Silent Threat of Asthma and COPD
Asthma attacks and COPD flare-ups, medically known as “eosinophilic exacerbations,” are more than just discomforting episodes—they can be fatal. Every day in the UK, dozens of lives are lost to these conditions.
These exacerbations, characterized by severe wheezing, coughing, and chest tightness, are primarily caused by inflammation due to elevated levels of eosinophils, a type of white blood cell. Alarmingly, eosinophilic inflammation is implicated in almost half of asthma attacks and up to 30% of COPD flare-ups.
Despite the severity of these conditions, medical treatments have remained largely stagnant for over 50 years. Steroid medications like prednisolone, which reduce lung inflammation, have been the primary line of defense.
However, steroids come with significant drawbacks, including side effects like osteoporosis and diabetes. Moreover, many patients either do not respond well to steroids or experience recurring symptoms that require repeated treatments or hospitalization.
A New Hope: Benralizumab
A recent clinical trial led by researchers at King’s College London has brought fresh hope to the fight against asthma and COPD. The team repurposed a drug called benralizumab, a monoclonal antibody currently used to treat severe asthma.
This innovative approach revealed that a single injection of benralizumab at the onset of an exacerbation is four times more effective than traditional steroid tablets.
“This could be a game-changer for people with asthma and COPD,” stated Professor Mona Bafadhel, the lead investigator of the study.
The Clinical Trial
Published in The Lancet Respiratory Medicine, the study divided participants at high risk of asthma or COPD attacks into three groups:
- Benralizumab injection and placebo tablets
- Standard steroid treatment (prednisolone) and placebo injection
- Combination of benralizumab injection and standard steroid treatment
The results were compelling. After just 28 days, participants receiving benralizumab reported significant reductions in respiratory symptoms such as coughing, wheezing, and breathlessness. By the 90-day mark, treatment failures in the benralizumab group were four times lower than those treated with steroids alone.
Moreover, patients in the benralizumab group experienced fewer follow-up episodes requiring medical attention and reported an improved quality of life.
“We’ve used the drug in a different way—at the point of an exacerbation—to show that it’s more effective than steroid tablets, which is the only treatment currently available,” said Professor Bafadhel.
Why This Matters
The potential implications of this discovery are monumental. COPD is the third leading cause of death worldwide, responsible for millions of fatalities annually. Yet, as Dr. Sanjay Ramakrishnan, the study’s first author, pointed out, “COPD treatment is stuck in the 20th century. We need to provide these patients with life-saving options before their time runs out.”
The findings also indicate that benralizumab could eventually be administered safely at home, offering greater convenience and accessibility for patients.
“We hope these pivotal studies will change how asthma and COPD exacerbations are treated for the future, ultimately improving the health for over a billion people living with asthma and COPD across the world,” added Professor Bafadhel.
Patient Testimonials: Real-Life Impact
The benefits of benralizumab are not just theoretical—they’re already changing lives.
Geoffrey Pointing, a 77-year-old patient who participated in the study, described the treatment as “fantastic.”
“I didn’t get any side effects like I used to with the steroid tablets. I used to never sleep well the first night of taking steroids, but the first day on the study, I could sleep that first night, and I was able to carry on with my life without problems,” he said.
Pointing also emphasized the relief the treatment provided during a flare-up. “Honestly, when you’re having a flare-up, you can hardly breathe. Anything that takes that away and gives you back a normal life is what you want.”
A Call for Change
Dr. Samantha Walker, director of research and innovation at Asthma + Lung UK, hailed the results as “great news for people with lung conditions.”
She highlighted the urgent need for new treatments, noting that every four minutes in the UK, someone dies from a lung condition. Globally, asthma and COPD cause a combined 3.8 million deaths annually.
“The big advance is the finding that targeted therapy works in asthma and COPD attacks,” said Professor Bafadhel.
The Future of Treatment
The discovery of benralizumab’s efficacy marks a turning point in the treatment of asthma and COPD. By addressing inflammation at its source, this targeted therapy offers a safer and more effective alternative to steroids.
As researchers continue to explore ways to make this treatment more accessible, the hope is that millions of patients worldwide will soon benefit from this medical breakthrough. From fewer hospital visits to improved quality of life, benralizumab represents a new era in managing chronic lung conditions.
In a field that has seen little progress for decades, this innovation is a beacon of hope for patients and their families. As Dr. Ramakrishnan aptly stated, it shows “massive promise” for the future of asthma and COPD care.
