Study 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.

Inclusion criteria

  • Comfirmed diagnosis of pulmonary alveolar proteinosis
  • Disease severity score (DSS) is 4-5

Exclusion criteria

Exclusion Criteria:

  • The acute respiratory infection
  • Heart failure (such as cardiogenic pulmonary edema)
  • The serious liver and kidney dysfunction (creatinine or were equal to or more than 2 times of the );
  • Pregnancy;
  • The patients with hereditary and secondary factors (inhalation of dust, hematological diseases, diseases, etc.);
  • DSS is 1-3;
  • The patient is allergic to the drugs that be used in our research;
  • The patients with poor compliance, or suffering from mental illness;
  • The patients have not signed ;
  • They were treated with whole lung lavage or regular GM-CSF therapy (treatment for more than 2 weeks) within 3 months before the enrollment.
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

  • Experimental
    GM-CSF

    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.

What researchers measure

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).

    Time frame: Up to 2 years

Secondary outcomes

  1. Relapse rate

    Time frame: Up to 2 years

  2. FEV1 difference

    Time frame: Up to 2 years

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 20, 2017, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
