About this study

Official title: Study of Subcutaneous Injection of Low-dose Recombinant Granulocyte Macrophage-Colony Stimulating Factor (rhGM-CSF) +/- Whole Lung Lavage(WLL) in Pulmonary Alveolar Proteinosis.

The purpose of this study is to establish an efficient and economic treatment scheme by evaluation of the safety and efficacy of subcutaneous injection of low-dose rhGM-CSF, or of similar injection after whole lung lavage , in patients with PAP.

Read the detailed description

The purpose of this study is to establish an efficient and economic treatment scheme by evaluation of the safety and efficacy of subcutaneous injection of low-dose rhGM-CSF, or of similar injection after whole lung lavage , in patients with PAP. During the observation, study visits will occur at the end of each month. During the 1-year follow-up period which is lasting 6 months after the treatment, all participants will be required to check the various efficacy indicators.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • rhGM-CSFDrug

    Also called TOPLEUCON, GM-CSF, Recombinant Granulocyte Macrophage-Colony Stimulating Factor, Granulocyte Macrophage-Colony Stimulating Factor

    GM-CSF will be given subcutaneously according to the rule in different groups.

  • Whole Lung Lavage(WLL)Procedure or surgery

    Also called Whole Lung Lavage, WLL

    using double lumen endotracheal tube (DLT) to selectively lavage one lung

Study groups in NCT01983657
Study groupRoleWhat they receive
D1ExperimentalPatients diagnosed with PAP will be received rhGM-CSF 1.25 ug/kg/d subcutaneously for 1 month, before evaluation on the 30th day (±3 day). If the treatment is effective, participants may be entered into low-dose group(D1)(rhGM-CSF administration 1.25 ug/kg/d, qd, sc, for 2 months,then rhGM-CSF administration 1.25 ug/kg/d, qod, sc, for 3 months), when the chest CT absorption≥25% , and /or the PaO2 elevated by 5 mm Hg.
Receives: Drug: rhGM-CSF
D2ExperimentalPatients diagnosed with PAP will be received rhGM-CSF 1.25 ug/kg/d subcutaneously for 1 month, before evaluation on the 30th day (±3 day). When the treatment is ineffective, and anti-GM-CSF antibody titers level ≥1:1000,the dose will be increased to 2.5 ug/kg/d. After 2 months, if the clinical response was optimal, that dose is continued for 3 months, and defined as group 2(D2).
Receives: Drug: rhGM-CSF
D3ExperimentalPatients diagnosed with PAP will be received rhGM-CSF 1.25 ug/kg/d subcutaneously for 1 month, before evaluation on the 30th day (±3 day). When the treatment is ineffective, and anti-GM-CSF antibody titers level ≥1:1000,the dose will be increased to 2.5 ug/kg/d. After 2 months, if the clinical response was not optimal, the patients will receive whole lung lavage(WLL), who are defined as group 3(D3).
Receives: Drug: rhGM-CSF
D4Active comparatorPatients diagnosed with PAP will be received rhGM-CSF 1.25 ug/kg/d subcutaneously for 1 month, before evaluation on the 30th day (±3 day). When the treatment is ineffective, and anti-GM-CSF antibody titers level <1:1000,the patients will receive whole lung lavage(WLL), then give rhGM-CSF administration (1.25 ug/kg/d) for 3 months, which belong to group4(D4).
Receives: Drug: rhGM-CSF; Procedure: Whole Lung Lavage(WLL)

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Improvements in double pulmonary diffuse lesions (Chest CT score )

    Measured: 6 months

Secondary outcomes (4)
  1. Clinical symptoms observation: shod of breath, cough (according to each score standard)

    Measured: 6 months

  2. Granulocyte Macrophage Colony Stimulating Factor(GM-CSF) Antibody titer change

    Measured: 6 months

  3. Improvements in pulmonary function

    Pulmonary function tests include residual volume/total lung capacity(RV/TLC), forced vital capacity(FVC), forced expiratory volume in one second/forced vital capacity(FEV1/FVC), diffusing capacity of carbon monoxide(DLCO).

    Measured: 6 months

  4. Improvements in arterial blood gas, including alveolar-arterial oxygen difference(A-aDO2), partial pressure of oxygen(PaO2), partial pressure of carbon dioxide in artery(PaCO2), arterial oxygen saturation(SaO2).

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing rhGM-CSF and Whole Lung Lavage(WLL) in people with Pulmonary Alveolar Proteinosis, run by Shanghai Pulmonary Hospital, Shanghai, China at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 18 Nov 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Huiping Li, Dr (86-13817389991, liw2013@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Improvements in double pulmonary diffuse lesions (Chest CT score ) (time frame: 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01983657, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Nov 2013.
