Blood Lymphocytes in Asthmatics Treated with Therapeutic Proteins ("BLAST") *ACTIVELY RECRUITING

Purpose: The BLAST study is being conducted to better understand how protein-based treatments effect the blood of patients with asthma.

Detailed Description: Group 2 innate lymphoid cells (ILC2s), a type of immune cell, tend to be increased in the sputum of asthma patients and have been determined a possible indicator for response to drugs. BLAST is an observational, clinic-based, single center study focused on understanding how therapeutic protein treatments alter inflammatory cells and blood inflammation. Along with gaining a better understanding of therapeutic protein treatments, this study intends to characterize components of the blood, including white blood cells, proteins, and genes in the blood of patients with asthma undergoing therapeutic protein treatments. Participants are asked to attend 1 – 3 visits over 18 months to provide blood samples and complete vitals and oximetry (how well oxygen binds to red blood cells), spirometry (breathing test), and post-bronchodilator reversibility (how much the airways can open when intaking puffs of albuterol).

Impact of Metabolic Dysfunction and Mucus Plugging on Asthma Physiology (“IMAP”)​ *ACTIVELY RECRUITING

Purpose: The objective of this study is to investigate changes in lung function during exercise in asthma patients with obesity and severe asthma patients. Metabolic dysfunction and mucus plugs will be measured in these groups, respectively, to answer the study's aim. 

Detailed Description: Participants will undergo a screening phase comprised of the maximum bronchodilator reversibility and methacholine challenge tests to determine evidence of asthma. Those in the severe asthma group will undergo a CT scan of the lungs to examine the presence of mucus plugs. All eligible participants will complete a Cardiopulmonary Exercise Test (CPET) at the UCSF Pulmonary Function Laboratory. The CPET is a procedure in which lung function is measured before, during, and after a stationary bike exercise test. Additionally, there is one required blood draw which can occur at any visit. 

This study involves 10 hours total for all visits over a span of up to 6 months. 

Please call (415) 502-0276​ for more information on the IMAP study.

Sorting and Expression Profiling of Airway Cells from Humans ("SEARCH") *ACTIVELY RECRUITING

Purpose: Because approximately half of all mild-moderately-severe asthma is persistently non-eosinophilic, it is important to determine prospectively if patients who are persistently non-eosinophilic differ in their benefit from inhaled corticosteroid treatment compared to patients who are not persistently non-eosinophilic.

Detailed Description: This is a single-site, longitudinal, mechanistic study of asthmatics and health controls. The primary objective of this study is to identify airway epithelial epigenetic enhancer signatures in asthma. Additionally, we plan to investigate the stability of Type-II and Non-Type-II pathways that are dysregulated in asthma by comparing and performing gene expression profiling on baseline and longitudinal samples. Study participation involves a characterization visit and baseline bronchoscopy, followed by a one-year sputum induction and a one-year bronchoscopy.

Tissue Immune Interaction in Nasal Polyposis (“TIP”)​ *ACTIVELY RECRUITING

Purpose: TIP aims to improve the understanding of persistent nasal and sinus swelling in patients with chronic rhinosinusitis with or without nasal polyps. Understanding of nasal and sinus inflammation will provide possible strategies for novel treatments.

Detailed Description: Chronic rhinosinusitis with nasal polyps (CRSwNP) is an inflammatory disease of the airway that results in extreme upper airway inflammation. Nasal polyps are fleshy swellings in the lining of the nose or sinuses and are more common in asthmatics with mucus buildup in their lower airways. Treatments currently available to treat airway inflammation are not completely effective. TIP is a cross-sectional study focused on gaining a better understanding of epithelial and immune cells and sino-nasal secretions (secretions from the nose and sinuses) in patients with CRSwNP. Those who participate in TIP will be asked to donate normally discarded tissue or leftover sinus content from their regularly scheduled sinus surgeries. Participants will also be asked to consent to nasal brushings, involving gentle brushing of the inner walls and spaces in the nose. In addition, participants may opt to attend an optional complete characterization visit at the UCSF Airway Clinical Research Center within 3 months of their procedures.

Please call (415) 502-0276​ for more information on the TIP study.

Characterizing the Rheological Properties of Pathologic Airway Mucus  ("CRAM")  *ACTIVELY RECRUITING

Purpose: The objectives of this study are to learn more about the physical properties of lung mucus in chronic airway diseases and to analyze how these properties are affected by mucolytic drugs.

Detailed Description: Involving up to 4 visits, participants will undergo breathing tests and provide samples of spontaneously expectorated sputum (phlegm). Participants will also be asked to collect samples of sputum at home using a provided collection kit and bring these samples with them to the research center for their visits. A single blood draw may be conducted.

Individuals diagnosed with either asthma, chronic obstructive pulmonary disorder (COPD), or non-cystic fibrosis bronchiectasis, who also often cough up mucus (phlegm) from their lungs may be eligible. 

Please call (415) 502-4328 for more information on the CRAM study.
