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

  • Older Adult

Accepts Healthy Volunteers

Yes

Sampling Method

Non-Probability Sample

Study Population

A total of up to 1000 participants will be recruited and enrolled into Cohort A (healthy participants), Cohort B (mild asthmatics), and Cohort C (moderate to severe asthmatics).

Enrollment will be monitored to, 1) ensure that no less than 30% of the study population in both Cohort B and Cohort C will be asthmatics with asthma onset before the age of 25 years (include 25 years); 2) ensure that at most 25% of participants who in both Cohort B and Cohort are current smokers or ex-smokers with a total smoking history of ≥10 pack years (not applicable for e-cigarettes); 3) ensure that at least 60% of participants in Cohort C have ACQ-5 ≥1.5; 4) ensure that no less than 30% of participants in Cohort C have severe asthma

Description

Inclusion Criteria:

  • Age 18 to 75 years of age
  • acceptable FEV1 (according to ATS and ERS)
  • compliance with study procedures All Asthma Cohorts
  • physician diagnosed Asthma greater or equal to 3 months prior to screening visit

Exclusion Criteria:

  • history of alcohol or drug abuse within the past year
  • pregnant at time of an assessment
  • has an altered mental status at the time of informed consent
  • receipt marketed or investigational biologic(s) within 3 months or 5 half-lives prior to visit 1, whichever is longer
  • history or current upper or lower respiratory infection or symptoms within 2 weeks of baseline assessments
  • terminal diseases and/or organ failure or participants otherwise considered not appropriate for the study participation

Design Details

Cohorts and Interventions

Group / Cohort
Cohort A
up to 100 healthy participants, non-smokers, non-asthmatic with pre-bronchodilator Forced expiratory volume in 1 second (FEV1) ≥80% predicted.
Cohort B
up to 300 mild asthmatics on as-needed low dose inhaled corticosteroids (ICS)-formoterol, or low dose ICS plus as-needed short-acting β2 agonists (SABA), without the need for other controller medication.
Cohort C
up to 600 moderate to severe asthmatics on low or medium dose ICS-long acting β2 agonists (LABA), high dose alone or in combination with LABA with pre-bronchodilator FEV1 < 80% predicted.
