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.

Design outcomes

Primary

MeasureTime frameDescription
Number of Participants With Stable or Improved Forced Vital Capacity (FVC) Response at 1 Year1 yearForced 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.
