Primary Outcome Measures:
  • Extent of Exposure to Bosentan in Patients With Idiopathic Pulmonary Fibrosis (IPF) [ Time Frame: Start of study to end of study, up to 21 months ]
    Mean extent of exposure to bosentan treatment in months

Secondary Outcome Measures:
  • Number of Patients Exposed to Bosentan Over Time [ Time Frame: Start to end of study, up to 21 months ]
    Numbers of participants exposed to bosentan treatment over time

  • Adverse Events (AE) Leading to Discontinuation of Study Drug. [ Time Frame: Start to end of study, up to 21 months ]
    Number of participants with at least one AE that led to permanent discontinuation of study treatment.

  • Treatment-emergent Serious Adverse Events (SAE) [ Time Frame: up to 21 months plus 28 days after the end of study drug ]
    Number of participants with at least one SAE during the study.

  • Occurrence of Liver Function Test (LFT: Alanine Aminotransferase (ALT) and Aspartate Aminotransferase (AST)) Abnormality. [ Time Frame: up to 21 months, plus 24 hours after the end of study treatment ]
    Number of participants with an increase in ALT and/or AST to > 3 times upper limit of normal during the study.
