Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 6 years and older
- All sexes
- No healthy volunteers
- Child, Adult, Older adult
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:
Who may be able to join
- 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.
Who cannot join
- 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

About this study
Official title: The Severe Asthma Research Program at Wake Forest University - Longitudinal Phenomics and Genetics of Severe Asthma.
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.
Read the detailed description
The mission of the SARP is to improve the understanding of severe asthma to develop better treatments. The SARP will gain a better understanding of asthma and its endotypes, in children and adults, by defining the disease at the molecular and cellular levels in the context of the temporal phenotypic expression of the disease. To this end, the SARP investigators will utilize both mechanistic and evoked phenotype approaches to: 1) characterize developmental molecular, cellular and physiologic phenotypes in children and adults with mild to severe asthma, and 2) to further elucidate the evolving pathobiology and pathogenesis of severe asthma and its sub-phenotypes and 3) compare these features over time. This approach involves a shared longitudinal protocol conducted across all participating centers which includes common information on all SARP participants. Additionally, SARP investigators have each identified mechanistic research questions to be included in the shared longitudinal protocol. At Wake Forest University investigators are specifically interested in genetic influences on disease severity and the use of statistical modeling techniques to better understand disease phenotypes. Together, these longitudinal and mechanistic approaches will enable prediction of phenotype stability/fluctuation and pharmacologic responses and identification of novel, disease-modifying targets for treatment.

Where is the study taking place?
The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in pulmonary function over time (time frame: 36 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01750411, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Apr 2021.
