Observational Registry Study With Sub-analysis (Patients Previously Randomized to LAMBDA 001) to Assess ProsperaTM Performance for Detection of CLAD After Lung Transplant (LAMBDA 002)

The LAMBDA 002 registry study is an observational, longitudinal, multicenter study observing patients undergoing lung transplant in one of the following two cohorts:

Cohort 1: Previously enrolled and randomized in LAMBDA 001 (transbronchial biopsy surveillance or Prospera surveillance) and enrolled at least 12 and up to 18 months post-transplant.

Cohort 2: Not previously randomized in LAMBDA 001 (may have been enrolled but randomization did not occur), Prospera testing is part of clinical care and enrolled during less than or equal to 12 months posttransplant.

Primary Objective:

The primary objective of the study is to assess the clinical utility of combining Prospera testing with routine transplant management in detecting acute rejection or infection events in patients receiving Prospera testing as part of their post-transplant clinical care.
