Chronic Cough Goes Beyond What You Hear
Chronic cough may impact the daily lives of patients with idiopathic pulmonary fibrosis (IPF) and non-IPF interstitial lung diseases (non-IPF ILDs)
Real Lives, Real Impact
Patients living with idiopathic pulmonary fibrosis (IPF) and non-IPF ILDs often experience chronic cough, a cough lasting at least 8 weeks.1-3 For many, the burden extends beyond the act of coughing alone and impacts them physically, emotionally, and socially.
Many patients with IPF and non-IPF ILDs experience chronic cough
~140k
U.S. patients with IPF4-6
60-70%
have uncontrolled chronic cough7

~228k
U.S. patients with non-IPF ILDS8
50-60%
have uncontrolled chronic cough3,9
Onset of IPF typically occurs in the seventh decade of life.10
Chronic cough is often persistent and severe
A survey conducted with the U.S. Pulmonary Fibrosis Foundation’s (PFF) Community Registry, resulted in insights from 197 patients self-reporting IPF or non-IPF ILDs and experiencing chronic cough (greater than 8 weeks).11
%
reported coughing episodes lasting more than 30 seconds
%
reported chronic cough for over 2 years
%
reported their cough severity as moderate to severe
IPF and non-IPF ILD-related chronic cough: A burden with no FDA-approved treatments
Patients with IPF and non-IPF ILDs describe chronic cough as unpredictable, difficult to control, and often unresponsive to commonly used approaches.
There are no FDA-approved treatments and current antifibrotics have not demonstrated a benefit in cough reduction.12-13
%
reported having no relief or only partial/somewhat relief with treatments that they are currently using or have tried in the past for their chronic cough11
“I have tried 15 different medications, not including over the counter products or cough suppressants, and nothing has worked for me.”
