Evaluating the Asthmatic Response to an Experimental Infection With Rhinovirus in the Atopic
United States26 participantsStarted 2013-09-01
Plain-language summary
In patients with asthma, reactions to allergens in the environment (such as mold, pollen, weed, domestic pets, and dust allergens) play an important role in causing asthma symptoms. However, upper respiratory tract infections, typically those caused by the common cold virus, rhinovirus, can also cause asthma to get worse. In previous studies at the University of Virginia, it was found that mild asthmatics, who had high levels of the allergy antibody (called IgE) in their blood, developed more persistent cold and chest symptoms when they were given an infection with rhinovirus (the most frequent cause of the common cold). The cold symptoms produced by rhinovirus tend to peak during the first 4 -7 days of the cold. These symptoms, including nasal congestion, are similar to what you have experienced with previous colds.
This study is being done to learn how a common cold caused by a viral infection affects people with asthma. The goal is to learn how to improve the care of asthma symptoms caused by the common cold virus (called rhinovirus). Most adults experience one or two colds caused by rhinovirus every year. In addition, 75-80% of asthma exacerbations caused by viral infections are caused by this virus, primarily in children. Adults are less likely to experience significant changes in their asthma symptoms when they get colds, because they have developed protective immune responses from previous colds which help diminish symptoms.

Inclusion Criteria • ALL SUBJECTS:
* Subjects must be able to understand and provide written informed consent
* Age 18 to \< 40 years of age, any gender, any racial/ethnic origin.
* Participant must be willing to comply with study procedures and requirements. Participant must be considered eligible for participation based on results of screening procedures conducted by protocol number 20100686 at VCU and IRB# 12656 at UVA.
Subjects with asthma
Criteria for inclusion will include those:
* with physician-diagnosed, mild asthma who are only using bronchodilators (e.g. albuterol) for symptom control.
* Asthma Control Test (ACT) Questionnaire Score a \> 19 at enrollment (See Appendix: Asthma Control Test).
* Short-acting beta-agonist use \< daily in last 4 weeks
* FEV1 \> 70%, or FEV1/FVC ratio \> 75% for subjects with FVC values between 80 and 87% predicted whose FEV1 values fall below 70%. a positive methacholine challenge test (i.e. at least a 20% fall in FEV1) at a methacholine concentration of 16 mg/ml or less (15). The methacholine test will not be done if subjects have used albuterol within 4 hours of the test procedure.Evidence for atopy demonstrated during screening (under IRB protocol# 12656) as judged by positive prick skin tests to one or more aero-allergens.
Control subjects. Criteria for inclusion will include those who do not have a history of asthma or allergic disorders (e.g. allergic rhinitis, atopic dermatitis, or food allergies).

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
