About this study

The clinical trial is designed to see if a new drug called HZN-825, can help people with IPF. The aim is to understand how the body responds to the new drug, and if it affects lung function.

People affected by IPF currently have limited treatment options to slow the progression of disease. New research studies such as this, are needed to gain valuable knowledge about better treatment options.


What is involved?

You will be randomly assigned to one of 3 groups:

  1. Taking the new drug in the morning and a look alike medicine (placebo) in evening
  2. Taking the new drug in the morning and the evening
  3. Taking a look alike drug (placebo) in both the morning and evening

You would be asked to take part for up to 52 weeks, with the possibility of remaining in the study for another 52 weeks.

Tests will take place at different time points in the study. This may include lung function tests, six-minute walk test, questionnaires and other medical monitoring.

Patients, care providers and researchers will not know which group participants are in until the end of the initial 52-week study.

Summary of involvement

Taking a new drug or placebo tablets morning and evening

Lung function tests


Other medical assessments
