Study Details

Study Description

Brief Summary

Clinical trial for subjects with autoimmune pulmonary alveolar proteinosis (aPAP) who have completed the IMPALA trial (NCT02702180).

At the Baseline visit, eligible subjects may continue or re-start treatment with 300 µg inhaled molgramostim (recombinant human Granulocyte-Macrophage Colony Stimulating Factor; GM-CSF) administered intermittently in cycles of seven days molgramostim, administered once daily, and seven days off treatment.

Subject will be treated with inhaled molgramostim for up to 36 months.

During the trial, whole lung lavage will be applied as rescue therapy.

Outcome Measures

Primary Outcome Measures

  1. Number of adverse events [36 months]

  2. Number of serious adverse events [36 months]

  3. Number of adverse drug reactions [36 months]

  4. Number of adverse events leading to treatment discontinuation [36 months]

Secondary Outcome Measures

  1. Alveolar-arterial oxygen gradient [36 months]

    Difference in oxygen tension between lungs and blood

  2. 6-minute walk distance [36 months]

  3. St Georges Respiratory Questionnaire total score [36 months]

    Respiratory-specific questionnaire measuring impact on overall health, daily life, and perceived well-being. Scores range from 0 to 100, with higher scores indicating more limitations.

  4. Frequency of whole lung lavages during the trial [36 months]

  5. Diffusion capacity of the lung for carbon monoxide [36 months]

  6. Forced expiratory volume in one second [36 months]

  7. Forced vital capacity [36 months]

  8. Arterial oxygen tension [36 months]

  9. Pulmonary alveolar proteinosis Disease Severity Score [36 months]

    Disease-specific score graded based on symptoms of PAP and oxygenation of blood. Scores range from 1 to 5, where 5 indicates most severe disease.

  10. Need for oxygen supplement therapy [36 months]

  11. Number of subjects not requiring treatment for pulmonary alveolar proteinosis [36 months]

  12. Time off treatment for pulmonary alveolar proteinosis [36 months]
