NCT01750411

Brief Summary

The mission of SARP is to improve the understanding of severe asthma through the integrated study of the effect of genetics on the clinical and biological features of asthma and to investigate how these change over time. The ultimate goal of these efforts is to promote better treatments for severe asthma.

Sampling MethodProbability Sample
Study Population

The target recruitment goal for each center is 75% adults (age 18 and older) and 25% children age 6-17 years. Within the pediatric age group, an attempt will be made to enroll equal numbers of children 6-11 and 12-17 years of age. Similarly, an attempt will be made to enroll at least 50% females and 30% minorities. Given the mission of SARP, a diverse sample of subjects with asthma is needed to gain better understanding of asthma and its endotypes. Because there are a number of respiratory disorders that may be confused with asthma or confound asthma assessment, SARP enrollees must meet the all following eligibility criteria as outlined below:

You may qualify if:

  • Physician diagnosis of asthma,
  • Age 6 years and older
  • Evidence of historical reversibility, including either:
  • FEV1 bronchodilator reversibility ≥ 12%, or
  • Airway hyperresponsiveness reflected by methacholine PC20≤16 mg/mL.

You may not qualify if:

  • No primary medical caregiver
  • Pregnancy (only if undergoing methacholine challenge or bronchoscopy)
  • Current smoking
  • Smoking history \> 10 pack years if ≥ 30 years of age or smoking history \>5 pack years if \< 30 years of age (Note: If a subject has a smoking history, no smoking within the past year)
  • Other chronic pulmonary disorders associated with asthma-like symptoms, including (but not limited to) cystic fibrosis, chronic obstructive pulmonary disease, chronic bronchitis, vocal cord dysfunction that is the sole cause of asthma symptoms, severe scoliosis or chest wall deformities that affect lung function, or congenital disorders of the lungs or airways
  • History of premature birth before 35 weeks gestation
  • Planning to relocate from the clinical center area before study completion
