About this trial
The International Severe Asthma Registry is a global initiative looking to ensure that the care of people with severe asthma will continue to improve by collecting detailed information about the health and treatment of as many people with the disease as possible. The study will gather anonymized longitudinal real-life data for participants with severe asthma for five years. The purpose of the registry is to track the progress of participants and determine how well they are responding to treatment. Medical research using data from the registry will give the investigators a better understanding of severe asthma and help the investigators develop and improve the care and treatment for severe asthma participants. The Canadian cohort of the registry will collect information from Canadian participants with severe asthma across seven different sites.
