Protocol for the European Multi-Centre Study Understanding Severe Asthma Longitudinal Assessment of Adults With Severe Asthma

Cross-sectional study to characterize cohorts of subjects with asthma and healthy controls in terms of clinical features, physiological measurements and non-invasive measurement of biomarkers and develop phenotype handprints for adults with severe asthma

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

  • Severe asthma cohorts: uncontrolled asthma symptoms or frequent severe exacerbations
  • Mild-moderate asthma cohorts: controlled or partially controlled asthma symptoms
  • Healthy controls: non-asthmatic healthy individuals free of significant disease

Description

General Inclusion Criteria:

  1. Able to give written informed consent prior to participation in the study, which includes ability to comply with the requirements and restrictions listed in the consent form. Informed consent must be obtained prior to undertaking any study procedures.
  2. Male or female subject aged 18 years or older at screening.
  3. Able to complete the study and all measurements.
  4. Able to read, comprehend, and write at a sufficient level to complete study related materials.
  5. Subjects will be allowed to enrol in other studies while taking part on this study. However, Permission from the Scientific Board must be obtained to enrol or allow the continued participation of a subject enrolled in another study.

General Exclusion Criteria:

  1. As a result of medical interview, physical examination or screening investigation the physician responsible considers the subject unfit for the study either because of the risk to the subject due to the study or the influence this may have on the study results.
  2. The subject has a history of recreational drug use or other allergy, which, in the opinion of the responsible physician, contra-indicates their participation.
  3. Subject is female who is pregnant or lactating or up to 6 weeks post partum or 6 weeks cessation of breast feeding. If a woman is subsequently found to have been pregnant at the time of an assessment data from that assessment will not be included in the analyses.
  4. The subject has participated within 3 months of the first dose in a study using a new molecular entity, or the first dose in any other study investigating drugs or having participated within three months in a study with invasive procedures. Any U-BIOPRED assessments should be deferred until 3 months after the first dose or invasive procedure. Permission from the Scientific Board must be obtained to enroll or allow the continued participation of a subject enrolled in another study.
  5. Those who, in the opinion of the investigator, have a risk of non-compliance with study procedures.
  6. The subject has a recent history of incapacitating psychiatric disorders
  7. History or current evidence of an upper or lower respiratory infection or symptoms (including common cold) within 2 weeks of baseline assessments (assessments should be deferred).
