Clinical Trials


The Levine group is involved in multiple clinical studies involving severe asthma, or asthma that is not well controlled by standard medications such as high-dose inhaled corticosteroids or oral prednisone. The goal of these clinical studies is to better understand why about 5-10% of asthma patients have severe asthma that is steroid-resistant, and to test whether new medications are effective for these patients.

While these studies are designed to uncover more information about severe asthma, people with mild or moderate asthma can also participate.

1. Severe Asthma Pioglitazone Clinical Trial 

The purpose of this study is to determine if a widely used drug for treating diabetes can improve asthma. Pre-clinical studies have shown that pioglitazone can reduce airway inflammation triggered by asthma allergens.

2. Longitudinal Observational Study of Severe Asthma 

This study will compare severe asthmatics with mild or moderate asthmatics or people without asthma over a long period of time. The purpose of the comparisons is to learn more about the factors that cause severe asthma. This information may help identify new treatments for people whose asthma is not well controlled by standard medications.

3. Genetics of Asthma Research Study 

This study looks to identify genes that may be involved in the development or severity of asthma. By uncovering the genes linked with severe asthma, researchers may be able to identify new targets for asthma therapies.

4. Sample Collections from the Airways of Asthmatic Patients 

The purpose of this study is to identify the factors that may cause airway inflammation in patients with asthma. This study involves a procedure called a fiberoptic bronchoscopy in which cells and fluids are collected from the airways using a pencil-thin tube that is passed into the lungs.

Eligible patients for any of these trials will receive a comprehensive evaluation at the NIH Clinical Research Center in Bethesda, Maryland. There is no cost to participate in any of the trials; studies #3 and 4 will also provide monetary compensation for those participating.
