Trial Description


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.

Further Study Information


  • 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.
