- Progression-free survival [ Time Frame: From baseline to week 54 ]Progression-free survival is a composite end-point of freedom from CLAD progression or death from any-cause. CLAD progression is defined as fall in FEV1 > 10% from the baseline (screening visit) FEV1 to the 12 month (week 54) visit.
- Time to fall in FEV1 > 10% [ Time Frame: From the baseline (screening) visit ]Defined as fall in FEV1 > 10% from the baseline (screening visit) FEV1
- Freedom from Bronchiolitis Obliterans Syndrome (BOS) grade 3 [ Time Frame: Week 54 ]BOS grade 3 is defined as FEV1 <50% of the best-post-transplant FEV1
- All cause mortality [ Time Frame: Week 54 ]
- CLAD-specific mortality [ Time Frame: Week 54 ]Defined as any death felt by the investigator to be at least partially related to CLAD.
- Freedom from acute rejection [ Time Frame: From baseline to week 54 ]Acute rejection defined as any biopsy proven episode of acute vascular (A1-A4) or airway (B1R or B2R) rejection.
- Freedom from the development of new donor specific anti-HLA antibodies [ Time Frame: From baseline to week 14 ]An anti-HLA antibody (any mean fluorescent intensity level) with specificity for a donor HLA type at 3 months which was not present prior to IMP treatment
- Freedom from CLAD progression [ Time Frame: From baseline to week 54 ]CLAD progression is defined as fall in FEV1 > 10% from the baseline (screening visit) FEV1 at 12 months.
- Rate of FEV1 decline [ Time Frame: From baseline to week 54 ]Rate of FEV1 decline is defined as the slope of the regression line for FEV1 between the screening visit and week 54
- Rate of FVC decline [ Time Frame: From baseline to week 54 ]Rate of FVC decline is defined as the slope of the regression line for FVC between the screening visit and week 54
- Change in 6-minute walk distance (6MWD) [ Time Frame: From baseline to week 54 ]Change in 6MWD is defined as the difference between the 6MWD at screening and the week 54 visit. Patients who have died by week 54 will receive a 6MWD of 0.
- Change in St George's Respiratory Questionnaire (SGRQ) Score [ Time Frame: From baseline to week 54 ]Change in SGRQ is defined as the difference between the total SGRQ at screening and the week 54 visit. Patients who have died by week 54 will receive a SGRQ of 0.
- Inpatient bed-days [ Time Frame: From baseline to week 54 ]This is defined as the aggregate of inpatient bed-days between the screening visit and week 54.
