Outcome Measures

Primary Outcomes (1)

  • Serum MMP7 Level

    The primary study endpoint was the change in MMP7 serum concentration (ng/ml) from baseline to 12 weeks. Serum MMP7 concentrations in peripheral blood are easily measureable and reflect changes in the alveolar microenvironment. Thus, we have chosen to study mean serum MMP7 concentrations after three months of CO treatment as a surrogate biomarker of the effect of inhaled CO administration on disease progression.

    Baseline to Week 12

Secondary Outcomes (4)

  • Total Lung Capacity % Predicted Values (TLC)

    Baseline to Week 12

  • Diffusing Capacity for Carbon Monoxide (DLCO) % Predicted Values

    Baseline to Week 12

  • Six Minute Walk Distance

    Baseline to Week 12

  • St George's Respiratory Questionnaire

    Baseline to Week 12
