Trial Information

Treatment of Idiopathic Pulmonary Fibrosis With Losartan: A Pilot Project


- 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
