Primary Outcome Measures:
  • Pulmonary deterioration [ Time Frame: 2 years ] [ Designated as safety issue: No ]
    decrease in Forced expiratory volume in 1 second (FEV1), vital capacity (VC), or Diffusing capacity of the lung for carbon monoxide (DLCO) of at least 15% as compared to baseline values and/or progression of clinical symptoms (general symptoms) and/or occurrence of pneumothorax


Secondary Outcome Measures:
  • Evolution of pulmonary volumes (FEV1) [ Time Frame: 6 months ] [ Designated as safety issue: No ]
  • Evolution of pulmonary lesions in High Resolution Computed Tomography (HRCT) [ Time Frame: 6 months ] [ Designated as safety issue: No ]
