g) Exclusion of other forms of interstitial lung diseases.
h) In patients > 50 years fulfilling all above mentioned criteria a BAL to exclude other causes of interstitial lung disease is sufficient and a lung biopsy is not necessary.

8. Previous administration of infliximab.

12. Active hepatitis- B or hepatitis-C.
13. Are considered ineligible according to the TB eligibility assessment, screening, and early detection of reactivation rules defined in Section 4.3.

15. Have current signs or symptoms of severe, progressive or uncontrolled renal, hepatic, hematologic, gastrointestinal, endocrine, cardiac, neurologic, or cerebral disease (including demyelinating diseases such as multiple sclerosis).
16. Concomitant congestive heart failure and/or cor pulmonale, including medically controlled asymptomatic patients. Criteria for cor pulmonale are based on cardiac sonography: estimated systolic pulmonary artery pressure > 40 mmHg at rest.
17. Presence of a transplanted organ (with the exception of a corneal transplant > 3 months prior to screening).
18. Malignancy within the past 5 years (except for squamous or basal cell carcinoma of the skin that has been treated with no evidence of recurrence).

|- Brief summary||Idiopathic Pulmonary Fibrosis (IPF) is a relatively rare interstitial lung disease of unknown etiology with a median survival between 2 and 4 years. Treatment of IPF is still a major therapeutic challenge; |
standard treatment includes corticosteroids and azathioprine or cyclophosphamide. However, the available studies on standard treatment of IPF have not proven a significant effect on survival.
There is compelling evidence for an important role of tumor necrosis factor-alpha(TNF-a) in the pathophysiology of IPF. TNF-a has a direct pro-fibrotic potential by stimulation of (myo)fibroblast proliferation and collagen synthesis and its role involves additional activities in regulation of inflammatory and immune responses. In animal models of fibrosis a pivotal role for TNF-a was demonstrated; induction of fibrosis could be inhibited by concomitant treatment with soluble TNF-a receptors.
Therefore, we hypothesize that the inhibition of TNF-a by the chimeric monoclonal anti-TNF-a antibody infliximab (Remicade®) will affect inflammatory and pro-fibrotic cytokine expression and thereby will slow-down disease progression in IPF.
Patients (n=18) treated with standard therapy (prednisolone and azathioprine) for at least three months will be randomly assigned to receive additional intravenous infliximab (5 mg/kg) or placebo at week 0,2,6,12,18,24,30,36,42 and 48.
Primary endpoints are change form baseline in Forced Vital Capacity and time to disease progression according to the ATS criteria. Secondary endpoints include among others analyses of pro-inflammatory and pro-fibrotic mediators and growth factors in broncholaveolar lavage fluid and serum.
