Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Time to Occurrence of Disease Worsening or Death up to End of Study. [ Time Frame: 36 months ]
    Disease worsening was defined as an event of worsening of pulmonary function tests (PFT) or acute exacerbation of idiopathic pulmonary fibrosis (IPF).


Secondary Outcome Measures :
  1. Percentage of Patients Who Experienced Either Disease Worsening or Death at 1 Year. [ Time Frame: 12 months ]
    Disease worsening was defined as an event of worsening of pulmonary function tests (PFT) or acute exacerbation of idiopathic pulmonary fibrosis (IPF).
