Asthma clinical trials at UCSF
14 in progress, 8 open to new patients

  • Analysis of Inflammation and Microbiome in Patients With Sinusitis and Asthma

    open to eligible people ages 18 years and up

    This is a cross-sectional, non-interventional study, consisting of three study arms, (1) Full Characterization (AIMS-Full), (2) Surgery Arm (AIMS-OR), and (3) Mucus Collection (AIMS-M). Participants will be recruited and enrolled in either AIMS-Full or AIMS-OR (based on participant availability). Participants who complete the initial characterization study (either AIMS-Full or AIMS-OR), may also go on to participate in the AIMS-M arm, which focuses mainly on sample collection. Participants who choose not to participate in either characterization arm are able to enroll directly into AIMS-M for sample collection only.

  • Characterization of Adult Subjects for Asthmatic Research Studies

    open to eligible people ages 18 years and up

    This study is designed to characterize subjects in terms of the nature and severity of their asthma and in terms of conditions that may alter the clinical expression of asthma. Some features will be obtained in all subjects. These include a medical history and baseline lung function tests. This characterization forms the basis for our database that facilitates research protocols.

  • Characterizing Asthma Sputum Elasticity in the UCSF Severe Asthma Research Program

    open to eligible people ages 18-65

    This study is designed to characterize subjects in terms of their sputum phenotype. The purpose of this study is to learn more about the impact of having abnormally elastic sputum on asthma severity by comparing subjects with severe as well as mild/moderate asthma to healthy controls. The characterization will include medical history, pulmonary function testing, imaging of the lungs and biospecimen collection.

  • Inpatient Clinical Trial of NAC

    open to eligible people ages 18-80

    The purpose of this study is to determine the beneficial effect of n-acetylcysteine (NAC), an inhaled medication that breaks down mucus, on lung function. NAC is a medication approved by the US Food and Drug Administration (FDA) for the treatment of chronic diseases of the respiratory system, including asthma. With CT lung imaging, the investigators seek to identify a subgroup of patients with asthma with a 'mucus' profile. This is a single-arm study which means all participants will receive the same treatment.

  • Interventions To Help Asthma Clinical Adherence

    open to eligible people ages 5-17

    To conduct a pilot test to estimate the effect of a novel reminder system in improving daily asthma controller medication adherence rates in children with monolingual Spanish-speaking guardians who have limited English Proficiency (LEP).

  • Sorting and Expression Profiling of Airway Cells From Humans (The SEARCH Study)

    open to eligible people ages 18-70

    This will be a single site, mechanistic study of asthmatic subjects and healthy, non-asthmatic controls involving a baseline characterization visit and a research bronchoscopy visit. We will identify differences in airway epithelial epigenetic enhancer signatures in asthma, by analyzing freshly isolated airway epithelial cells from healthy controls and from well-characterized subjects with asthma.

  • Study of the Inflammation and Airway Changes That Occur After Exposure to Allergen in Asthmatics

    open to eligible people ages 18-50

    This protocol describes a single site mechanistic study to investigate microRNAs (miRNAs) that are differentially expressed in the airway epithelium of patients with asthma at baseline and in response to allergen challenge. We hypothesize that allergen exposure enhances airway smooth muscle contractility and epithelial cell mRNA/miRNA production as a consequence of locally increased T-cell derived cytokine production. The study will involve three visits over the course of approximately 14 days. At Visit 1, participants will be characterized in detail with lung function testing, methacholine challenge testing, and allergen skin prick testing. At Visit 2, participants will undergo bronchoscopy with segmental allergen administration of either cat or dust mite standardized allergen extract. At Visit 3 (either 24 hours later or 7 days later), bronchoscopy will be performed to collect airway samples including bronchoalveolar lavage (BAL), epithelial brushings and endobronchial biopsies. Sample analysis will include measurement of miRNA and mRNA expression in epithelial brushings (RNAseq and qPCR); analysis of cell surface markers on BAL cells and blood cells; and collection of endobronchial biopsies for immunostaining of immune cells localization, immunoblotting of smooth cell protein phosphorylation, analysis of mucin content and smooth muscle cell subculture. A total of 38 subjects (26 asthmatics with stable or well-controlled asthma, 6 allergic non-asthmatics and 6 non-allergic non-asthmatics) will complete the study.

  • User-Friendly Spirometer and Mobile App for Self-Management and Home Monitoring of Asthma Patients

    open to eligible people ages 6-15

    The primary goal of this proposal is to use an in-home, smartphone-enabled, hand-held spirometer to determine the FEV1% predicted ranges that predict the Yellow Zone threshold.

  • Pulmonary Specialist-Health Coach Consult Model Pilot

    Sorry, not yet accepting patients

    The Pulmonary Specialist-Health Coach Consultation (PuSHCon) study examines the implemention of health coach-assisted consultations to improve access to specialist care and implementation of specialist recommendations for patients with COPD, asthma, and asthma COPD overlap syndrome (ACOS) for low-income and vulnerable patients seen at public health clinics. A limited number of patients (50) from two clinics will be enrolled in the pilot study; 25 patients from one clinic will receive a pulmonary consultation under usual care and 25 patients from the other clinic will receive the PuSHCon model.

  • Chitinases and Transforming Growth Factor Beta (TGFB) in Human Asthma

    Sorry, in progress, not accepting new patients

    The purpose of this study is to find out the roles of two specific gene families (the chitinase gene family and the TGFB family). We hypothesize that chitinases and TGFb pathway genes will be differentially expressed in the airways of non-asthmatic subjects and subjects with asthma. We further hypothesize that genetic variants in CHIT1, AMCase, and TGFb pathway genes that show associations with asthma and related phenotypes will change the expression and/or function of the protein of these genes in the airway in several ways, including the transcript numbers for full length genes and splice variants and, for the chitinase genes, the levels of chitinase activity in airway secretions.

  • Clinical Trial of NAC in Asthma

    Sorry, in progress, not accepting new patients

    This study evaluates 20% n-acetylcystine (NAC) in the treatment of moderate-to-severe asthma that is complicated by mucus in the airway, as determined by CT imaging. The study is a crossover design, which means that half the study participants will get 20% NAC in the first 7-day treatment period and placebo in the next 7-day treatment period; and the other half will get placebo in the first 7-day treatment period and 20% NAC in the next 7-day treatment period.

  • Role of microRNAs in T Cell-Driven Inflammation in Asthma

    Sorry, in progress, not accepting new patients

    This will be a single center study of asthmatic subjects and healthy controls which will investigate mechanisms of asthma through detailed molecular analysis of airway tissues and fluids. The primary goal will be investigate the role of microRNAs in Th2-driven inflammation in asthma. The investigators hypothesize that asthma is associated with abnormal expression of miRNAs in T cells which favors differentiation into Th2-cells. The investigators further hypothesize that asthma is heterogeneous based on the presence and absence of Th2-driven inflammation and that abnormalities in T cell miRNA expression will be most prominent in a subgroup with high levels of Th2-driven inflammation (as assessed using molecular markers that the investigators have previously established). Finally, the investigators hypothesize that inhaled corticosteroids will normalize the T-cell miRNA abnormalities observed in asthma, as corticosteroids treat Th2-driven inflammation. The samples collected will also facilitate the pursuit of secondary analyses designed to investigate mechanisms of inflammation and remodeling in asthma as well as molecular phenotypes of asthma.
