## Abstract

PROJECT SUMMARY/ABSTRACT
Idiopathic pulmonary fibrosis (IPF) is a rare, but devastating interstitial lung disease characterized by a
progressive decline in lung function and a median survival of 3-5 years after diagnosis. Despite the poor
prognosis, IPF follows a highly variable clinical course, whereby most patients experience gradual disease
progression, some demonstrate relative stability and a small group dies from rapidly progressive disease. Anti-
fibrotic therapies were recently approved for the treatment of IPF, but it remains unclear which IPF phenotypes
derive the most benefit. Recent advances in genomic technology provide an excellent opportunity to improve
our understanding of IPF progression and treatment response. In this proposal, I aim to take advantage of
these genomic advances to identify single nucleotide polymorphisms (SNPs) linked to relevant IPF outcomes. I
will do this using DNA samples collected from patients enrolled in past and current IPF clinical trials, along with
two large IPF registries. My central hypothesis is that patients genetically predisposed to death, disease
progression and treatment response can be prospectively identified using SNPs linked to these endpoints. I will
first conduct a genome-wide survival analysis to identify SNPs linked to early IPF mortality. I will then genotype
relevant susceptibility and outcome-associated SNPs in several clinical trial datasets to determine whether
they predict relevant trial endpoints, including pulmonary function decline and hospitalization. Finally, I will
genotype SNPs at potential pharmacogenetic loci to determine whether such SNPs modulate the response to
anti-fibrotic therapy. This work will advance my long-term career goal of incorporating genetics into clinical
decision-making in patients with IPF. Concurrently I will pursue a career development plan that will provide
outstanding mentorship, hands-on laboratory experience and additional training in genetic epidemiology,
statistical genetics, and bioinformatics. This K23 award is vital to successful completion of this proposal and
timely execution of my career development plan, as it will provide the time necessary to meet the realistic
milestones that have set in conjunction with my advisory committee. Ultimately this award will allow me to
successfully compete for R01 funding aimed at advancing my long-term goal above.
