Study Details

Study Description

Brief Summary

Rationale: A big step forward and great opportunity to improve overall efficacy of bronchoscopic lung volume reductioen is to combine treatment modalities aiming to close the dependent collateral channels and then proceed with EBV therapy to induce lobar collapse, and thus maximal treatment effect.

Objective:
Primary objective:
  1. To investigate the feasibility of injecting AeriSeal into the interlobar collateral ventilation channels region to make the target lobe suitable for endobronchial valve treatment.
Secondary objectives:
  1. To investigate the safety of injecting AeriSeal into the interlobar collateral ventilation channels region to make the target lobe suitable for endobronchial valve treatment.

  2. To investigate the effectiveness of injecting AeriSeal into the interlobar collateral ventilation channels region to make the target lobe suitable for endobronchial valve treatment.

  • Outcome Measures

    Primary Outcome Measures

    1. feasibility - Target Lobar Volume Change on Chest -CT scan [3 months]

      To investigate the feasibility of injecting AeriSeal into the interlobar collateral ventilation channels region to make the target lobe suitable for endobronchial valve treatment

    Secondary Outcome Measures

    1. safety - Number and specification of reported (S)AEs per individual patient and as aggregate [3 months]

      To investigate the safety of injecting AeriSeal into the interlobar collateral ventilation channels region to make the target lobe suitable for endobronchial valve treatment. Thsi by collection of all adverse events, and specifically: death, pnuemothorax, pneumonia, COPD exacerbation, and post treatment inflammatory response.

    2. changes in Quality of Life as measured by the SGRQ [3 months]

      By measuring the absolute change in The St George's Respiratory Questionnaire total score (0-100 points with higher scores indicating poor QOL)

    3. effectiveness - Measurement of change in Forced Expiratory Volume in one second (FEV1). [3 months]

      By measuring changes in relative% in FEV1(L)

    4. effectiveness - Measurement of change in Residual Volume (RV) [3 months]

      By measuring the change in absolute mL in RV

    5. effectiveness - Measurement of changes in 6-minute walk test (6MWT) [3 months]

      By measuring the absolute change in meters in the 6MWT

    6. changes in Quality of Life as measured by the COPD Assessment Test (CAT) [3 months]

      By measuring the absolute change in CAT score (0-40, with higher score indicating poor QOL)
