Brief summary
RATIONALE: Losartan may be effective in treating patients with idiopathic pulmonary fibrosis. PURPOSE: This clinical trial is studying the side effects of losartan and to see how well it works in treating patients with idiopathic pulmonary fibrosis.
Detailed description
OBJECTIVES: * 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, Carbon monoxide diffusing capacity (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.
Interventions
50 mg losartan taken daily by mouth in capsule form for 1 year

Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of Participants With Stable or Improved Forced Vital Capacity (FVC) Response at 1 Year | 1 year | Forced vital capacity (FVC) must be \>= 50% at baseline. Stable FVC response is defined as a -5% change in FVC from baseline up to a +5% change from baseline. Improved FVC response is defined as 5% or greater increase in the predicted value of FVC on pulmonary function testing following 12 months of treatment. |

Outcome results
Number of Participants With Stable or Improved Forced Vital Capacity (FVC) Response at 1 Year
Forced vital capacity (FVC) must be \>= 50% at baseline. Stable FVC response is defined as a -5% change in FVC from baseline up to a +5% change from baseline. Improved FVC response is defined as 5% or greater increase in the predicted value of FVC on pulmonary function testing following 12 months of treatment.
