The purpose of this study is to evaluate the safety and effectiveness of infliximab in the treatment of subjects with sarcoidosis with pulmonary involvement who show symptoms of the disease even though they are currently being treated with medication. Patients will receive either placebo, 3 mg/kg infliximab, or 5 mg/kg infliximab infusions at weeks 0, 2, 6, 12, 18, and 24. Safety evaluations will be performed at specified intervals throughout the study and will consist of laboratory tests, vital signs (such as blood pressure), physical examinations and the occurrence and severity of adverse events as well as other study specific procedures.

Patients will receive infusions of Infliximab (Remicade) 3 or 5 mg/kg or placebo at weeks 0, 2, 6, 12, 18 and 24.
