Brief Summary:
BUILD 3 is a prospective, multicenter, randomized, double-blind, parallel group, placebo-controlled, event-driven, group sequential, phase III superiority study. The primary objective is to demonstrate that bosentan delays disease worsening or death in patients with Idiopathic Pulmonary Fibrosis.

Arm Intervention/treatment
Experimental: Bosentan
Subjects receive bosentan 62.5 mg twice daily (b.i.d.) for 4 weeks followed by bosentan 125 mg b.i.d (if body weight > 40 kg) or bosentan 62.5 mg b.i.d. (if body weight < 40 kg)
Drug: Bosentan
Bosentan 62.5 mg tablets twice daily (b.i.d.) for 4 weeks followed by bosentan 125 mg tablets b.i.d (if body weight > 40 kg) or bosentan 62.5 mg tablets b.i.d. (if body weight < 40 kg)
Other Names:
  • Ro 47-0203
  • ACT-050088

Placebo Comparator: Placebo
Subjects receive placebo matching the bosentan treatment regimen
Drug: Placebo
Placebo matching bosentan 62.5 mg tablets and 125 mg tablets

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).
