Inclusion criteria

Inclusion criteria: 1. Subject must be =18 years of age, at the time of signing the informed consent. Specific for Japan; Subject must be =20 years of age, at the time of signing the informed consent. 2. A serum anti-GM-CSF autoantibody test result confirming autoimmune PAP. 3. History of PAP, based on examination of a lung biopsy, bronchoalveolar lavage (BAL) cytology, or a high-resolution computed tomogram (HRCT) of the chest. 4. DLCO 70% predicted or lower at the first screening and Baseline visits. 5. Change in % predicted DLCO of 85% during 15 minutes without use of supplemental oxygen at the Screening visits. 8. Male or female 9. Contraceptive use by men or women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies. a. Male subjects: Males agreeing to use condoms during and until 30 days after last dose of trial treatment, or males having a female partner who is using adequate contraception as described below. b. Female subjects: 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 20

Exclusion criteria

Exclusion criteria: 1. Diagnosis of hereditary or secondary PAP, or a metabolic disorder of surfactant production. 2. WLL performed within 3 months prior to baseline. 3. Requirement for WLL at screening or baseline. 4. GM-CSF treatment within 6 months prior to baseline. 5. Treatment with rituximab within 6 months prior to baseline. 6. Treatment with plasmapheresis within 6 weeks months prior to baseline. 7. Treatment with any investigational medicinal product within 5 half-lives or 3 months (whichever is longer) prior to baseline. 8. Previously randomized in this trial. 9. History of allergic reactions to GM-CSF or any of the excipients in the nebulizer solution. 10. Inflammatory or autoimmune disease of a severity that necessitates significant (e.g. more than 10 mg/day systemic prednisolone) immunosuppression. 11. Previous experience of severe and unexplained side-effects during aerosol delivery of any kind of medicinal product. 12. History of, or present, myeloproliferative disease or leukemia. 13. Apparent pre-existing concurrent pulmonary fibrosis, or diagnosis of interstitial lung disease other than aPAP. 14.Acute or unstable cardiac or pulmonary disease that may be aggravated by exercise or confound assessment of the primary endpoint: including presence of pulmonary edema, or diagnosis of chronic obstructive pulmonary disease (COPD), pulmonary vasculitis, or pulmonary hypertension. 15. Known active infection (viral, bacterial, fungal, or mycobacterial) that may affect the efficacy evaluation in the trial. 16. Physical disability or other condition that precludes safe and adequate exercise testing. 17. Any other serious medical condition which in the opinion of the Investigator would make the subject unsuitable for the trial 18. Pregnant, planning to become pregnant during the trial, or breastfeeding woman.
