## Abstract

ABSTRACT – OVERALL PROGRAM
More than 25 million Americans suffer from asthma, and nearly half do not have their asthma under control.
Standard treatment is limited, and a stepped care approach is applied uniformly to all patients regardless of the
underlying mechanisms of asthma. Our Asthma Inflammation Research [AIR] Program aims to uncover
fundamental mechanisms of asthma and identify biomarkers of those pathways that will define mechanistic
endotypes of asthma in order to target therapies in a precision medicine approach of care. In Cycle I of the
TPPG, we uncovered new mechanisms of airway inflammation and hyper-reactivity. In Cycle II, we apply the
fundamental discoveries to precisely target pathways for bronchodilation (Project 3) and inflammation (Projects
1 and 2). Based on findings that oxidative metabolism mechanistically contributes to asthma, Project 1
investigates whether diet can modulate inflammatory responses, gene expression, and airway reactivity.
Metabolic endotypes will be elucidated, and a specific biomarker of eosinophil activation, bromotytrosine
(BrTyr) is tested in asthma control and biologic-based therapies of asthma. Project 2 has identified T-Helper 17
[TH17] pathways in origins of severe asthma. In Cycle II, Project 2 determines if, and how, TH17 cytokines
drive pathologic inflammation, and uses the information to develop serum biomarkers of this endotype, and
small molecule inhibitors and peptidomimetics of IL-17A for treatment of asthma. Project 3 shows that high
levels of nitric oxide (NO) and oxidants in asthmatic airways damage soluble guanylate cyclase (sGC), making
it NO-insensitive and diminishing the NO-sGC pathway from acting in bronchodilation. In Cycle II, Project 3
develops bronchodilator drug response profiling to identify sGC endotypes, and tests sGC activators and
stimulators in asthma preclinical models to support a new indication for sGC drugs as bronchodilators. The
projects benefit from model systems and efficiencies of cores, including a new Technology Development and
Commercialization Core B, and innovative murine models of asthma and airflow imaging in Core C.
Partnerships with Pharmaceutical & Biotechnology, Nutrition, Health & Wellness companies, and strategic
leveraging of Cleveland-based NHLBI National Centers for Accelerating Innovation (NCAI-CC) and the NSF
Innovations Corps at Cleveland Clinic ensure that our discoveries will be implemented over the next 5 years.
Altogether, the program provides an unparalleled opportunity for efficient progression of personalized asthma
care products to the marketplace for patients.
