Idiopathic Pulmonary Fibrosis | The Effect of Pirfenidone on Cough in Patients With Idiopathic Pulmonary Fibrosis

Idiopathic Pulmonary Fibrosis research study

What is the primary objective of this study?

In this study we evaluate the effect of Pirfenidone on cough and quality of life in patients with idiopathic pulmonary fibrosis (IPF) that are treated with Pirfenidone in daily practice. The hypothesis is that Pirfenidone will decrease cough and increase quality of life.

Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.

Cough IPFMale and female with idiopathic pulmonary fibrosis and cough and about to start on Pirfenidone according to regular practice will be asked to wear a cough monitor 24 hours before starting Pirfenidone and twice 24 hours while using Pirfenidone. Patients will also be asked to fill in questionnaires about quality of life and cough.
