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.

Description
- INCLUSION CRITERIA:
To be eligible for this protocol, participants must:
- Have a molecular diagnosis of HPS-1 or HPS-4
- Be 18-70 years of age
- Have the expectation to live more than 3 months, i.e., an FVC greater than or equal to 30% of predicted
Have evidence of severe pulmonary fibrosis, i.e.:
- A FVC less than or equal to 45% of predicted
- Reduced exercise tolerance lasting longer than 1 week on the Dyspnea Perception Scale
- No evidence of improvement in pulmonary fibrosis within the past year, as defined by an FVC increase of 10% or a DLco increase of 15%.
- Be available, willing, and able to come to the NIH Clinical Center for admission every 3 months.
EXCLUSION CRITERIA:
- An explanation for interstitial lung disease other than HPS, including but not limited to radiation, sarcoidosis, hypersensitivity pneumonitis, bronchiolitis obliterans organizing pneumonia, cancer
- Pregnancy or lactation
- History of ethanol abuse or recreational drug use in the past two years
- History of human immunodeficiency virus (HIV) or chronic viral hepatitis infection
- Chronic use of high-dose steroids (greater than 10 mg prednisone/day) intended for ongoing treatment of their interstitial lung disease
- Use of any of the following within 28 days of enrollment: investigational therapy, cytotoxic/immunosuppressive agents other than corticosteroids, including but not limited to azathioprine, cyclosphosphamide, methotrexate, cyclosporine, colchicine, interferon gamma-1b, bosentan;
- Any severe medical complication including but not be limited to uncontrolled seizures, repeated transient ischemic attacks, severe ataxia, uncontrolled migraine headaches, diplopia, repeated episodes of syncope, an untreated psychiatric disorder, recent myocardial infarction (past 6 months), unstable angina, clinically relevant and untreated arrhythmias, uncontrolled hypotension or hypertension (systolic blood pressure less than 80 or greater than 180 mm Hg), myocarditis, severe congestive left sided heart failure, hepatomegaly not due to right heart failure, renal glomerular impairment (creatinine clearance less than 35 ml/min/1.73 m(2)), pancreatitis, toxic thyroiditis, life-threatening malignancy;NOTE: right sided heart failure due to pulmonary hypertension as a result of pulmonary fibrosis will not be considered an exclusion criteria.
- Significant laboratory abnormalities, including but not limited to serum potassium less than 3.0 or greater than 5.4 mEq/L, SGPT greater than 100 U/L, CK greater than 700 U/L, hemoglobin less than 9.0 g/dL, platelets less than 70 k/mm(3), leukocyte count less than 2.0 k/microL;
- For women of child-bearing age, failure to have an effective method of birth control. Oral contraceptives will be considered inadequate without a second method due to risk of reduced efficacy of BCP while taking Zileuton.
- Severe psychiatric disease untreated. Inability to give informed consent after reading or having the consent read to the participant in their native language. Any concern that there is a therapeutic misconception will be evaluated by genetic counselor and/or appropriate mental health professionals prior to acceptance into the study
