Clinical Trial Summary

Clinical trial for subjects with autoimmune pulmonary alveolar proteinosis (aPAP) who have completed the IMPALA trial (NCT02702180). At the Baseline visit, eligible subjects may continue or re-start treatment with 300 µg inhaled molgramostim (recombinant human Granulocyte-Macrophage Colony Stimulating Factor; GM-CSF) administered intermittently in cycles of seven days molgramostim, administered once daily, and seven days off treatment. Subject will be treated with inhaled molgramostim for up to 36 months. During the trial, whole lung lavage will be applied as rescue therapy.

• Males agreeing to use using acceptable contraceptive methods.
• Willing and able to provide signed informed consent.

Exclusion Criteria:

• Treatment with GM-CSF products other than molgramostim nebuliser solution within three months of Baseline.
• Treatment with any investigational medicinal product other than inhaled molgramostim within four weeks of Baseline.
• History of allergic reactions to GM-CSF.

• History of, or present, myeloproliferative disease or leukaemia.
• Apparent pre-existing concurrent pulmonary fibrosis.
• Any other serious medical condition which in the opinion of the investigator would make the subject unsuitable for the trial.
