Brief Summary:

Rhinovirus (RV) infections represent the most common cause of asthma exacerbations in children and adolescents. The investigators hypothesize that the immune responses generated in the nose of allergic rhinitics and asthmatics underlie subsequent systemic modulation of the immune system, and that - in susceptible individuals (i.e., those with pre-existing asthma) - this modified nasal milieu is responsible for the asthma exacerbation.

Open label single center study in asthmatics as well as allergic rhinitis (AR) and healthy controls. All subjects will undergo good manufacturing practice (GMP) RV16 inoculation and responses will be compared between the 3 cohorts.


Condition or disease Intervention/treatment Phase
Asthma Allergic Rhinitis Biological: Rhinovirus (GMP RV16 HRV-16) Phase 2

Detailed Description:

Primary objectives are:

To determine whether RV increases expression of interleukin (IL)-25 transcripts by nasal epithelial cells in the asthma and AR but not control cohorts at the peak of infection (days 3 and 4).

To determine whether RV increases lower respiratory symptoms in the asthma but not AR and control cohorts.

To determine whether asthmatics and allergic rhinitics will demonstrate an increased severity of infection in comparison to control subjects.

Secondary objectives are:

  1. To determine whether asthmatic and AR cohorts demonstrate increased IL-25 transcript expression over the course of RV infection
  2. To determine whether asthmatic and AR cohorts demonstrate increased expression of mRNA transcripts of a type 2 cytokine-inducing profile (IL-33 and thymic stromal lymphopoietin (TSLP)).
  3. To determine whether increased transcript expression of this type 2 cytokine-inducing profile can be corroborated as increased expression of protein.
  4. To determine whether RV infection in the asthma cohort is associated with increases in biomarkers of inflammation.
  5. To determine whether increased severity of RV infection in the asthma and AR cohorts will be associated with more symptoms.
  6. To determine whether increased severity of RV infection in the asthma and AR cohorts is related to decreased innate immunity.

Criteria

Inclusion Criteria:

All subjects:

  1. Subjects must be able to understand and provide written informed consent.
  2. Age 18 to ≤40 years of age, any gender, any racial/ethnic origin
  3. Female subjects of childbearing potential must have a negative pregnancy test upon study entry (day -7) and before each procedure involving pharmacologic interventions (days 0, 4, and 7).
  4. Female (and male) subjects with reproductive potential, must agree to use FDA approved methods of birth control for the duration of the study such as, but not limited to, birth control pills, contraceptive foam, diaphragm, IUD, abstinence, or condoms.
  5. Participants must be willing to comply with study procedures and requirements.
  6. Negative test for serum neutralizing antibody to RV16 at enrollment visit (<1:8) (Visit 1).

Allergic Rhinitis Subjects:

  1. Allergy as determined by ≥1 positive prick skin test (wheal ≥5 mm diameter and 3mm larger than the diluent control) to Virginia inhalant panel within 5 years, and a history of symptoms of sneezing, rhinorrhea, pruritus, nasal congestion, and/or allergic conjunctivitis on natural exposure to relevant allergens.
  2. Negative methacholine challenge (less than 20% decline in functional expiratory volume in 1 second (FEV1) at ≤8mg/ml) within 1 year
  3. FEV1 ≥80% predicted, FEV1/FVC ≥80%.
  4. No history of wheezing with viral infection in the last 6 years, and no use of rescue inhalers or long-term controllers for asthma in the last 6 years.

Allergic Asthmatic Subjects:

  1. Allergy as determined by ≥1 positive prick skin test (wheal ≥5 mm diameter and 3mm larger than the diluent control) to Virginia inhalant panel. Subjects are not required to have allergy symptoms at the time of study. Subjects will report history of symptoms of sneezing, rhinorrhea, pruritus, nasal congestion, and/or allergic conjunctivitis on natural exposure to relevant allergens.
  2. Asthma determined by physician diagnosis and by a positive methacholine challenge (at least 20% fall in FEV1 at a methacholine concentration of ≤8 mg/ml) at screening protocol visit before enrollment (obtained within the past year).
