Eligibility
Inclusion criteria
Inclusion criteria: - aPAP diagnosed by CT, or by biopsy, or by Broncho Alveolar Lavage (BAL), and by increased GM-CSF autoantibodies in serum - Stable or progressive aPAP (i.e. absolute VC not improved by more than 5% and/or DLCO not improved by more than 10% - assessed from medical records) during a minimum period of two months prior to the Baseline visit - PaO2 4 percentage points on the 6 Minute Walk Test (6MWT) - An (A-a)DO2 of minimum 25 mmHg/3.33 kPa - Female or male =18 years of age - Females who have been post-menopausal for >1 year or females of childbearing potential after a confirmed menstrual period using a highly efficient method of contraception (i.e. a method with =65 years) yes F.1.3.1 Number of subjects for this age range 35
Exclusion criteria
Exclusion criteria: - Diagnosis of hereditary or secondary pulmonary alveolar proteinosis (PAP) - WLL within one month of Baseline - Treatment with GM-CSF within three months of Baseline - Treatment with rituximab within six months of Baseline - Treatment with plasmapheresis within three months of Baseline - Treatment with any investigational medicinal product within four weeks of Screening - Concomitant use of sputum modifying drugs such as carbocystein or ambroxol - History of allergic reactions to GM-CSF - Connective tissue disease, inflammatory bowel disease or other autoimmune disorder requiring treatment associated with significant immunosuppression, e.g. more than 10 mg/day systemic prednisolone - Previous experience of severe and unexplained side-effects during aerosol delivery of any kind of medicinal product - History of, or present, myeloproliferative disease or leukaemia - Known active infection (viral, bacterial, fungal or mycobacterial) - 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

| Main Objective: To compare efficacy of inhaled molgramostim on the Alveolar-arterial oxygen difference ((A-a)DO2) with placebo after 24-weeks treatment. ; Secondary Objective: Key Secondary objectives: - To compare efficacy of inhaled molgramostim on tolerance to exercise with placebo after 24-weeks of treatment - To compare efficacy of inhaled molgramostim on respiratory disease-related quality of life with placebo after 24-weeks of treatment - To compare efficacy of inhaled molgramostim based on time to Whole Lung Lavage (WLL) with placebo during 24-weeks of treatment. - To compare safety of inhaled molgramostim with placebo in terms of reported adverse events (AEs), serious adverse events (SAEs), adverse drug reactions (ADRs), severe AEs and withdrawals due to AEs during 24-weeks treatment ;Primary end point(s): Absolute change from baseline of (A-a)DO2 after 24-weeks treatment;Timepoint(s) of evaluation of this end point: After 24-weeks treatment | — |
