SPIROMICS Study of Early COPD Progression (SOURCE)

Parametric Response Mapping captures the change in lung density between matched inspiratory and expiratory images thereby enabling the distinction between normal lung parenchyma (PRMNORM), emphysema (PRMEMPH), and non-emphysematou...

Impact of Metabolic Dysfunction and Mucus Plugging on Asthma Physiology

We will compare change in EELV during the CPET (Cardiopulmonary Exercise Test) between the obese asthma patients with MD or without MD and between the patients with severe asthma with mucus plugs or without mucus plugs.

Tissue Immune Interaction in Nasal Polyposis

This study enrolls chronic rhinosinusitis patients with and without nasal polyps. Investigators aim to compare the percentage of ILC2 and tuft cells present in nasal tissue and secretions between those who present with nasal polyp...

Lung Function Outcomes Following Removal of Airway Mucus Plugs in Patients With Asthma (FOCUS)

We will assess change from baseline FEV1 one week after and six months after removal of mucus plugs by bronchoscopy.

PrecISE (Precision Interventions for Severe and/or Exacerbation-Prone Asthma) Network Study

Assessed prior to bronchodilator administration. Efficacy analyses will compare the end-of-period outcome values between test treatment and placebo.
