NCT03316651

Brief Summary

The purpose of the study is to evaluate the effectiveness of the sequential therapy with whole lung Lavage (WLL)/inhaling granulocyte-macrophage colony stimulating factor, compared to WLL only, for adult patients with severe autoimmune pulmonary alveolar proteinosis in China over a two-year period.

Outcome Measures

Primary Outcomes (1)

  • Time to the first relapse (the date: day/month/year)

    The standard of relapse: the condition of the disease after GM-CSF inhalation meeted the standard of effective treatment or the stability criteria, and then the condition deteriorated and meeted the deteriorate standard. The standard of effective treatment: oxygenation improvement (an increase in PaO2 of more than 10mmHg and / or a reduction in A-aDO2 more than 10mmHg). The stability criteria: an increase or a reduction in PaO2 of less than 10mmHg and / a reduction or an increase in A-aDO2 of less than 10mmHg. The deteriorate standard: deteriorate oxygenation (a reduction in PaO2 of more than 10mmHg and / or an increase in A-aDO2 of more than 10mmHg).

    Up to 2 years

Secondary Outcomes (2)

  • Relapse rate

    Up to 2 years

  • FEV1 difference

    Up to 2 years

Study Arms (1)

GM-CSF

EXPERIMENTAL

After the patients were randomly divided into two groups, they will receive whole lung lavage (WLL), and then one of the two groups with continue the next step as follows: Induction period: The time of beginning is 1 week after whole lung lavage, aerosolized GM-CSF was given for 7 days (150ug bid), and then the durg was stopped for 7 days, the 2 weeks was designed as a cycle, a total of 6 cycles (3 months) were known as the induction period. Maintenance period: maintenance period came up after the induction period. The dose of aerosolized GM-CSF was reduced to 150ug/d for three times a week, and then the durg was stopped for 7 days, the 2 weeks was designed as a cycle and maintenance period lasted for 9 months.
