Title: Pulmonary Rehabilitation in Fibrotic Pulmonary Sarcoidosis (Stage IV): Randomized Controlled Trial
Brief Summary: The primary objective of the study is to assess the improvement of daily activity in subjects with Stage IV Pulmonary Sarcoidosis one year after the conduct of a pulmonary rehabilitation program.

The secondary objectives are the following:

* assess the improvement of daily activity at several times : 2, 6 and 12 months after the beginning of a pulmonary rehabilitation program
* assess the improvement of exercise capacity by tests used in medical practice
* assess the correlation between daily activity and exercise capacity
* assess the improvement of dyspnea
* assess the improvement of quality of life and psychological state

In case at Visit 2 the results do no longer satisfy the entry criteria, the Investigator has to decide whether it is justified that the patient remains on study drug. The justification for decision needs to be documented. Laboratory parameters that are found to be abnormal at Visit 1 are allowed to be re-tested (once) if it is thought to be a measurement error (i.e. there was no abnormal result of this test in the recent history of the patient and there is no related clinical sign) or the result of a temporary and reversible medical condition, once that condition is resolved\].
