Asthma Clinical Trial
Official title:
Phosphodiesterase 4 Inhibitor, Roflumilast, Improves Beta Agonist Responsiveness Compared to Placebo in Low T2 Asthma Patients.
This study evaluates the effects of roflumilast on restoring response β2 adrenoreceptor agonists in low T2, obese asthmatics. One group of participants will receive roflumilast for 3 months, while the other will receive a placebo.
T2 low asthma is common in obese asthmatics. New evidence suggests that hyperinsulinemia and insulin resistance, both common in obesity, are associated with an increased risk of concurrent asthma. Targeting Phosphodiesterase 4 inhibitors (PDE4) allows for examination of a mechanism potentially linking obesity and asthma as well as identification of readily available and safe options to treat hyperinsulinemic, overweight asthmatics. It is hypothesized that obesity and hyperinsulinemia contribute to asthma by impairing β2 adrenoreceptor function and that this can be rescued the PDE4 inhibitor, roflumilast. ;
