The Landscape of Asthma Research in Britain
Around 5.4 million people in the UK receive treatment for asthma, and for a significant portion of them, standard medications do not fully control their symptoms. The NHS spends considerable resources on asthma care each year, yet severe asthma accounts for a disproportionate share of hospital admissions and emergency visits. This reality has driven a quiet but steady expansion of research activity across the country, with major centres in London, Manchester, Birmingham, and Plymouth running studies that look at everything from new biologic therapies to better ways of using existing treatments.
The Severe Asthma Research Programme at the University of Plymouth, for instance, has been gathering data from multiple NHS Trusts across Devon, Somerset, and Northumberland to understand how severe asthma affects health-related quality of life over time. Their work highlights something researchers have long suspected: the experience of severe asthma shifts with the seasons, and a patient's quality of life can look very different in the middle of winter compared to a spell of settled summer weather.
Meanwhile, the Manchester Asthma and Allergy Study, a longitudinal birth cohort study that has been tracking participants into adulthood, continues to uncover links between early-life exposures and respiratory outcomes decades later. This kind of long-view research is particularly valuable because it helps clinicians understand why some children grow out of their asthma while others carry it into their thirties and beyond.
What many people do not realise is that the UK has a well-established infrastructure for connecting patients with research opportunities. The NIHR Be Part of Research platform allows anyone to search for asthma trials recruiting near their postcode, and the process of getting involved is often simpler than expected. You do not need a referral from a consultant, although having a confirmed asthma diagnosis from your GP is usually the starting point.
Types of Trials and Who They Suit
Not all asthma trials are the same, and the range of options can be broader than people imagine. Some studies test new biologic injections for severe eosinophilic asthma—the kind that leaves patients reliant on repeated courses of prednisolone. Others compare different inhaler combinations or explore whether breathing retraining programmes, delivered through apps or online physiotherapy, can reduce reliance on reliever inhalers. There are even trials investigating whether dietary adjustments or weight management programmes can shift the trajectory of difficult-to-control asthma.
The table below gives a sense of how different types of trials compare in practical terms.
| Trial Category | Example Focus | Typical Duration | Suitable For | Key Considerations |
|---|
| Biologic therapy trials | Severe eosinophilic or allergic asthma | 12 to 52 weeks | Adults with uncontrolled severe asthma despite high-dose ICS/LABA | Regular hospital visits for injections; may require blood monitoring |
| Inhaler and medication studies | New combination inhalers, smart inhaler devices | 8 to 24 weeks | Mild to moderate asthma | Less invasive; often fewer site visits |
| Lifestyle and behavioural trials | Breathing retraining, diet, exercise programmes | 12 to 26 weeks | All asthma severities | Can sometimes be done remotely; useful for those who prefer non-drug approaches |
| Paediatric asthma research | Children's asthma management, early intervention | 6 to 52 weeks | Children aged 5 to 17 | Parental consent and involvement required; child-friendly clinic environments |
| Observational studies | Biomarker sampling, quality-of-life tracking | Single visit to 12 months | All asthma patients | No experimental treatment involved; contributes to broader scientific understanding |
Emma, a 28-year-old from south London, had been on high-dose steroid inhalers for nearly a decade when her consultant at Guy's Hospital mentioned a biologic trial for patients with eosinophilic asthma. "I was nervous about the commitment," she recalls, "but my asthma had been landing me in A&E at least twice a year. The trial team explained everything clearly, and I decided it was worth a try." She has now been on the study for over a year, and her hospital admissions have dropped to zero. Her experience is not unusual for patients who find the right match between their condition and the trial they join.
Finding a Trial and What to Expect
The most practical starting point for anyone curious about asthma clinical trials is the NIHR Be Part of Research website. You can enter your postcode and filter by condition, location, and how far you are willing to travel. Many trials reimburse reasonable travel expenses, and some provide parking permits for hospital sites—small but meaningful details that make participation more feasible for people who do not live next door to a major research hospital.
Asthma + Lung UK, the charity formed from the merger of Asthma UK and the British Lung Foundation, also runs a helpline where trained respiratory nurses can discuss research participation and point you in the direction of trials that might suit your circumstances. Their website carries listings of studies actively recruiting, and they have been vocal advocates for making research more inclusive—particularly for people from ethnic minority backgrounds, who have historically been underrepresented in asthma trials despite being disproportionately affected by severe asthma.
When you express interest in a trial, the first step is usually a screening call or visit. A research nurse or coordinator will go through your medical history, current medications, and asthma control in detail. They will explain what the study involves, how many visits are required, and what the potential risks and benefits might be. This is also your chance to ask questions—about time commitments, whether you can continue seeing your usual GP, and what happens if your asthma worsens during the trial.
Consent is an ongoing process in UK research. You can withdraw at any point without it affecting your usual NHS care, and the research team will continue to look after your asthma needs regardless. This safeguard is built into the ethical framework that governs all clinical trials in the country, overseen by the Health Research Authority and local NHS ethics committees.
Regional Research Centres and Specialist Clinics
The geography of asthma research in the UK means that opportunities are not confined to London. Royal Brompton and Harefield Hospitals in the capital remain a hub for severe asthma research, but equally active programmes exist at Heartlands Hospital in Birmingham, the University of Manchester's respiratory research group, and the Newcastle upon Tyne NHS Foundation Trust. The University Hospitals Sussex NHS Foundation Trust in Brighton has a dedicated respiratory unit with a same-day care facility, and its asthma nurse specialists work closely with research teams to identify patients who might benefit from trial participation.
Scotland has its own network of research-active respiratory clinics, and the Scottish Intercollegiate Guidelines Network (SIGN) collaborates with NICE and the British Thoracic Society on asthma guidance that shapes trial design across the UK. Patients in Glasgow, Edinburgh, and Aberdeen can access trials through their local NHS boards, often with referral from their respiratory consultant.
For those living in more rural areas, the picture can be patchier, but remote and decentralised trials are becoming more common. Some studies now use telephone consultations, wearable peak flow monitors, and smartphone apps to collect data, reducing the need for frequent travel to a central site. This shift has been particularly helpful for patients in Cornwall, the Scottish Highlands, and rural Wales, where the nearest research hospital might be a three-hour drive away.
What to Consider Before Joining
Trial participation is not for everyone, and weighing the pros and cons honestly matters. The time commitment can be real—some studies require weekly visits for the first month, then monthly check-ins for a year or more. Blood tests are common, and certain trials involve bronchoscopy or sputum induction, which some people find uncomfortable. On the other hand, participants often receive closer monitoring of their asthma than they would through routine NHS care, and they gain access to treatments that are not yet available on prescription.
It is also worth understanding that some trials are placebo-controlled, meaning you might not receive the active treatment. The research team will explain the randomisation process and the likelihood of receiving a placebo. In many asthma trials, participants on placebo still receive their usual standard-of-care medications, so no one is left without treatment.
The British Thoracic Society and NICE jointly publish guidelines that shape what counts as standard care in UK asthma management, and these guidelines inform the design of trials as well. Knowing that a study is built on this foundation of established clinical standards can provide reassurance.
Another practical point: if you are considering a trial that involves a biologic injection, check with the research team about storage requirements. Some biologics need refrigeration, and the study will clarify whether doses are administered at the hospital or whether you will be trained to self-inject at home. Either way, the logistics are usually discussed in detail during the consent process.
Making the Decision
If your asthma has been stubborn, unpredictable, or has been wearing down your quality of life despite following your treatment plan, looking into clinical trials could be a sensible next step. Start by browsing the NIHR Be Part of Research listings, or speak with your GP or respiratory consultant about what might be available locally. The Asthma + Lung UK helpline is another resource worth using, especially if you want to talk through your options with someone who understands both the clinical and the human side of living with difficult asthma.
Research in the UK continues to move forward, and the studies recruiting today are laying the groundwork for the treatments that could become routine in the years ahead. Whether you decide to participate or not, knowing what is out there is its own kind of reassurance.
