Primary outcomes

  1. Change in 6-Minute Walk Distance (6MWD) at Day 60

    Change in 6MWD at Day 60

    Time frame: Baseline to Day 60

Secondary outcomes

  1. Change in 6MWD at Day 30

    Change in 6MWD at Day 30

    Time frame: Baseline to Day 30

  2. Relief of symptoms on Day 30 and Day 60

    Time frame: Baseline to Day 30 and Day 60

  4. Change in oxygenation

    Change in oxygenation at Days 30 and 60, as measured by the SpO2/FiO2 ratio

    Time frame: Baseline to Day 30 and Day 60

  5. Change in biomarker levels

    Change in biomarker levels: plasma lipocalcin-2, matrix metalloproteinase-7, hepatocyte growth factor

    Time frame: Baseline to Day 60
