|Study Start Date:||March 2009|
|Primary Completion Date:||March 2012 (Final data collection date for primary outcome measure)|
50 mg tablets of losartan taken daily by mouth for 1 year
50 mg losartan taken daily by mouth in capsule form for 1 year
Other Name: losartan potassium
- Evaluate the effects of losartan potassium on disease progression in patients with idiopathic pulmonary fibrosis.
- Determine the safety of this drug in these patients.
OUTLINE: This is a multicenter study.
Patients receive oral losartan potassium daily for 1 year in the absence of disease progression or unacceptable toxicity.
Patients undergo pulmonary function tests with gas diffusion lung volumes, DLCO tests, and 6-minute walk tests at baseline and then at 3, 6, 9, and 12 months. Patients also complete baseline/transition dyspnea index questionnaires at baseline and then at 1, 3, 6, 9, and 12 months.
