The clinical trial led by a King’s College London academic followed patients who had been injected with tezepelumab every four weeks for a year. Tezepelumab is a type of antibody which targets parts of the immune system, reducing lung inflammation.

Treatment with tezepelumab was also shown to significantly improve asthma symptoms, lung function, and overall quality of life. During the study, two-thirds of patients stopped having any asthma attacks. These improvements were seen as early as two weeks into treatment and lasted for the duration of the study.

Scientists are trying to identify alternative treatments for managing severe asthma, as long-term daily steroid use can lead to serious health problems, including osteoporosis, diabetes, and increased vulnerability to infections.
