About this trial
Objective: To evaluate the potential impact of molecular phenotyping of transbronchial biopsies in lung transplant recipients with allograft dysfunction, and the potential for developing a safer endobronchial mucosal biopsy format.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
All lung transplant recipients undergoing a biopsy as determined by their surgeon or physician.
Disqualifiers
Patients who declined participation or unable to give informed consent.
Trial population
Patients with functioning lung transplant biopsied to determine their graft dysfunction or to confirm good function as per standard of care.
Trial design
Cohort
Prospective
Treatments tested in this trial
Lung transplant biopsy bites.
Procedure/SurgeryIn the second phase of the study, two biopsy bites from the same patient will be collected to assess tissue sampling variability.
Treatment groups
Trial outcomes
Primary outcomes
Report the molecular scores (probability) of lung transplant disease in a reference set of 600 transbronchial biopsies.
Molecular classifier predicts antibody mediated and T cell mediated rejection, and chronic allograft dysfunction.
Report the molecular diagnoses of the MMDx-TBB system
Compare MMDx readings to standard-of-care TBB histology and clinical diagnosis of CLAD.
Secondary outcomes
Report the molecular scores (probability) of lung transplant disease in a reference set of 600 mucosal endobronchial biopsies.
Molecular classifier predicts antibody mediated and T cell mediated rejection, and chronic allograft dysfunction.
Report the molecular diagnoses of the MMDx-3BMB system
Compare MMDx-3BMB readings to MMDx-TBB readings and clinical diagnosis of CLAD
Report the molecular changes over time in medically indicated follow-up biopsies
Predict and monitor response to anti-rejection treatment.
