Brief Summary:
Improvement of quality of life in patients with BO and establishment of a new third line therapy

Condition or disease Intervention/treatment Phase
Steroid-refractory Bronchiolitis Obliterans Drug: Interferon gamma 1b Phase 2

Detailed Description:

Primary Objectives:

Objective improvement of lung function, i.e.:

  • Improvement of SO2, pO2 or pCO2 in oxygen dependent or improvement of FiO2 in respiration dependent patients ≥ 20 % or
  • Reduction of oxygen need in oxygen dependent patients ≥ 1L O2/min with constant parameters at blood gas analysis (BGA) or
  • Improvement of obstructive parameters ≥ 20 % or
  • Improvement of lung function score (LFS) at least about one grade Improvement of lung function should be detectable at least by two consecutive examinations of lung function or BGA within at least four weeks.

Secondary Objectives

  • Morphological improvement of BO/BOOP at CT scan
  • Reduction of steroids about at least 20 %
