The purpose of the study is to help doctors learn more about investigational dupilumab (the study drug) and to find out how safe it is and how well it works for patients with asthma. The study will investigate whether the study drug can help to improve the health of your lungs, reduce the inflammation in your airways and also improve your quality of life. If you join the study, your participation will last a minimum of 29 weeks and up to 41 weeks and is planned to include approximately 153 participants. The study will be conducted worldwide. If the study is suited for you, you will be randomized by chance (like drawing straws) to receive either the study drug (300 mg dupilumab) or placebo.

Candidates for this study may or may not report disturbances in odor perception as their primary reason for seeking treatment at MUSC. This study is designed to collect long term, observational data from patients who are being treated with routine clinical care in health clinics at MUSC. Data from clinical questionnaires will be de-identified and stored in a database.

Asthma has high morbidity and mortality among adolescents and among youth from non-urban (i.e., rural and suburban) communities, both of whom are seldom included in asthma intervention research. This study will test the effectiveness and cost-effectiveness of high school-based intervention delivered by Community Health Workers (CHWs) to non-urban adolescents with uncontrolled asthma, and will examine factors associated with delivery of the intervention.

The TRANSFORM network is focused on improving child health outcomes in SC through research on conditions of highest priority for future generations. These include conditions like asthma, autism, diabetes, obesity and early childhood outcomes. To accelerate research study recruitment activities for future projects that TRANSFORM sites may participate in, the TRANSFORM network sites will create a research recruitment registry of families interested in volunteering for research. Participants will enter their own as well as their child(ren)'s information into the electronic registry which can be used to identify people to contact for future studies.
