Brief Summary:
Idiopathic pulmonary fibrosis (IPF) is a progressive disease for which there is no effective treatment. Interferon-gamma is a medication that has been used for other lung diseases to decrease scarring and fibrosis. Studies of interferon-gamma injected under the skin did not show any improvement in survival in patients with IPF. We hypothesize that giving interferon-gamma as a nebulized mist directly into the lungs can affect the immune system in a way that decreases fibrosis.

Condition or disease Intervention/treatment Phase
Pulmonary Fibrosis Drug: aerosol interferon-gamma Phase 1

Detailed Description:
Patients with mild-to-moderate idiopathic pulmonary fibrosis (IPF) will be enrolled in a phase I study of aerosol interferon-gamma (IFN-γ). Prior to initiation of treatment, patients will undergo CT of the chest, pulmonary function testing, and bronchoscopy with bronchoalveolar lavage. They will also undergo a lung deposition study to determine the lung dose of IFN-γ that will be delivered with each treatment. Patients will then receive aerosol IFN-γ 100mcg delivered three times weekly via nebulizer for one year. Study patients will be followed monthly to monitor potential side effects, vital signs, and progression of IPF symptoms. Labs will be drawn at regular intervals to monitor for side effects and to measure cytokine levels. Bronchoscopy will be performed at the 6 and/or 12 month visit to compare cytokine levels pre-, during, and post-treatment.

  • Patient with known life threatening asthma or severe COPD.
  • Patient requiring oxygen therapy for maintenance of adequate arterial oxygenation at rest.
  • Patient with hypersensitivity to study medication or other component medication.
  • Patient with known severe cardiac disease, severe peripheral vascular disease or seizure disorder which may be exacerbated by study drug administration (contraindications to drug administration as per package insert).
  • Pregnant or lactating; Females of child-bearing potential will be required to have negative pregnancy test and be required to use accepted form of birth control (abstinence for study duration is the preferred method).

  • CBC outside specified limits: WBC < 2,500/mm3, hematocrit < 30 or > 59, platelets < 100,000/mm3.
  • Creatinine > 1.5X upper limits normal at screening.
  • Drugs for therapy for pulmonary fibrosis, including corticosteroids, azathioprine and/or cyclophosphamide, or n-acetylcysteine within the previous six weeks.
  • Prior therapy with any class of interferon medication.
  • Investigational therapy for any indication within the last 28 days.
  • In a pulmonary rehabilitation program or planning to attend a pulmonary rehabilitation program.
