Study start date: February 22, 2022

Actual date on which the first participant was enrolled.

The overall goal of this study is to understand biological responses related to dupilumab treatment among severe asthma patients. Not all asthma is the same, and characteristics of asthma vary from person to person. The study will investigate whether the study drug can help to improve the health of participants lungs, boost immune response, as well as improve quality of life.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details

15 patients to be enrolled

Total number of participants that the clinical trial aims to recruit.

Basic Science Study

Basic science studies help researchers understand how the body works or how a disease develops. They don't test treatments, but they build the foundation for future therapies.

Eligibility

Researchers look for people who fit a certain description, called eligibility criteria: person's general health condition or prior treatments.

Criteria

6 inclusion criteria required to participate
Physician-diagnosed/managed severe asthma patients that are clinically eligible for dupilumab
Current treatment with a medium-to-high-dose inhaled glucocorticoid (fluticasone propionate at a total daily dose of greater or equal (≥) 440 μg or equipotent equivalent) plus up to at least one additional controller (e.g., a long-acting β2-agonist or leukotriene receptor antagonist)
Eosinophilic asthma phenotype (blood eosinophil level >300) or asthma requiring daily oral corticosteroids
Asthma that is uncontrolled, as defined by a score on the Asthma Control Test of 19 or lower, or a worsening of asthma in the past year that led to an asthma hospitalization, Emergency Department visit, or 3 days of oral corticosteroids
Show More Criteria
9 exclusion criteria prevent from participating
Patients with diagnosis of other chronic lung diseases (e.g. Chronic obstructive pulmonary disease (COPD), idiopathic pulmonary fibrosis, Churg-Strauss syndrome, Allergic bronchopulmonary aspergillosis, etc.)
Current smoker or reported smoking within 1 month of the screening visit (tobacco or any inhaled recreational product)
Greater than 10 total pack-year of cigarette smoking history
Treatment with oral corticosteroids for an asthma exacerbation 1 month prior to screening or during the screening period
