Often when people with asthma get a virus caused by the common cold (rhinovirus), they also experience an increase or worsening of their asthma symptoms. The purpose of this study is to see if the study medication dupilumab helps prevent those with mild to moderate asthma from having increased asthma symptoms, after being exposed to an experimental rhinovirus inoculation. This is a study about dupilumab which is a drug approved by the U.S. Food and Drug Administration (FDA) for treatment of moderate to severe asthma. Dupilumab is a medication that blocks pathways that cause asthmatic inflammation in the lungs, leading to symptoms and worsening lung function. During this study, subjects will be given either dupilumab or placebo and will subsequently be exposed to the the "common" cold virus (rhinovirus). The virus that the investigators are using has been safely used before in many studies like this involving thousands of volunteers, and the safe use of the virus in this research study has been reviewed by the FDA. The investigators will track asthma symptoms during the study with lung function tests, questionnaires, specimen collection, biomarkers, and physical exams. For data analysis the investigators will assess the samples collected to determine changes in the treatment groups. The investigators will also asses the symptom scores and deviations from baseline measures for lung function.
Rhinovirus (RV) is responsible for up to 70-80% of asthmatic exacerbations in children and adolescents requiring urgent care or hospitalizations. Understanding the mechanism by which this otherwise relatively innocuous infection produces asthma exacerbations is essential towards mitigating these episodes. Two theories have been proposed to explain this phenomenon. One is that asthmatics have defective innate and adaptive immune responses to viral respiratory infections, leading to increased viral-associated pathology with an associated enhanced inflammatory response. An alternative - and not mutually exclusive - explanation is that RV indirectly exacerbates an ongoing allergic response to bystander allergens. Dupilumab blocks type 2 inflammatory responses and is known to prevent asthma exacerbations. It both attenuates the reduced innate immunity observed in asthmatics and also reduces the ability to engage a type 2 allergic inflammatory response to bystander allergens. Therefore, the investigators hypothesize that RV mediated worsening of asthma will be attenuated in the presence of dupilumab. This study examines cellular and molecular mediators of these interactions, which could help understand the intimate mechanism(s) underlying dupilumab's protective effect in asthmatics.
A total of 60 patients with mild persistent asthma will be enrolled and randomized in this study (30 active treatment and 30 placebo).
The double-blind, randomized design minimizes any sources of bias. The placebo group provides a reference for the interpretation of study results, so the net effect of dupilumab could be discerned. The dupilumab dose regimen selected for this study (300 mg q2w after an initial loading dose of 600 mg) is consistent with the approved dose for patients with asthma. The primary objective of the study is to evaluate the effect of dupilumab on innate antiviral and type 2 inflammatory biomarkers, epithelial barrier repair, and adaptive immune responses following rhinovirus infection in asthmatic patients. The exploratory objectives include evaluating the effect of dupilumab in reducing the severity of rhinovirus-induced respiratory symptoms, its effect on lung function (eg FEV1, FEV1/FVC) and asthma control. As well as evaluating the effect of dupilumab on other biomarkers and viral load. The sample size was selected empirically, informed by similar successful studies conducted in the past. For example, in a previous double-blind, placebo-controlled randomized trial of omalizumab in the prevention of RV-induced asthma exacerbations, a total n of 20 (10 per group in the final analysis) was sufficient to achieve a secondary endpoint based on FEV1/FVC ratio). These data demonstrate the intrinsic power of the viral challenge model. The population included in the current trial has been further enriched (mild to moderate persistent asthmatics, on ICS ± other long-term controllers).

Exclusion Criteria:
Women of childbearing potential* who are unwilling to practice highly effective contraception prior to the initial dose/start of the first treatment, during the study, and for at least 4 months after the last dose. Highly effective contraceptive measures include:
<!-- -->
sexual abstinence†, ‡.
Postmenopausal women must be amenorrheic for at least 12 months in order not to be considered of childbearing potential. Pregnancy testing and contraception are not required for women with documented hysterectomy or tubal ligation.
Sexual abstinence is considered a highly effective method only if defined as refraining from heterosexual intercourse during the entire period of risk associated with the study treatments.
The dupilumab dose regimen selected for this study (300 mg q2w after an initial loading dose of 600 mg)
Drug: Dupilumab Injectable Product
A harmless substance that looks like the study drug, but which should have no effect. The placebo formulation used in this study contains all the ingredients present in the active drug, except the active ingredient (IL-4α antibody). Therefore, the risk related to this formulation should be no greater than the risk associated to the active drug.
