Pilot Study of a Multi-Drug Regimen for Severe Pulmonary Fibrosis in Hermansky-Pudlak Syndrome
This study will examine whether five drugs (pravastatin, Losartan, Zileuton, N-acetylcysteine and erythromycin) used together can slow the course of pulmonary fibrosis (scarring of the lung tissue) in patients with Hermansky-Pudlak Syndrome (HPS). Patients with this disease have decreased skin color (albinism), bleeding problems, and sometimes colon problems. Two of the known types of Hermansky Pudlak syndrome, type 1 and type 4, are at high risk of pulmonary fibrosis between the ages of 30 and 50.
Patients 18 to 70 years of age who have Hermansky-Pudlak Syndrome with a serious loss of lung function due to pulmonary fibrosis may be eligible for this study.
Participants begin taking pravastatin on study day 2 and start a new drug every 3 days. Patients who experience no problems with the medicines return home and continue on the drugs for the next 2 years. They return to the NIH Clinical Center every 3 months for a medical history, physical examination, and blood, urine and lung function tests. CT and bone density scans are done every year. The study may continue for up to 3 years.
