ASCENT – Asthma control in severe asthma patients treated with tezepelumab: a prospective, observational, real-world evidence study
This study involves primary data collection within real-world settings of participants who start treatment with tezepelumab for severe uncontrolled asthma. This study will complement evidence obtained from randomized controlled trials and provide new data focusing on the holistic and patient reported outcomes.

Purpose of trial
Healthcare is aware of the importance of patient important outcomes data in the real-world in order to complement results from randomised clinical trials. This study will assess the impact of tezepelumab treatment as per the participant’s perspective on asthma symptom control, lung function, health-related quality of life, and key patient-reported outcomes in a real-world setting.
ASCENT will assess asthma symptom control, lung function, and patient-reported outcomes after starting tezepelumab treatment. Patient-reported outcomes are increasingly being used to assess patient experience and impact with disease and treatment, as there can be a disconnect between effects of treatment on objective measures of disease versus patient-reported outcomes.
