Lung Transplant Research

Ex Vivo Lung Perfusion (EVLP)
Study title: Novel Lung Trial: Normothermic Ex Vivo Lung Perfusion (EVLP) as an Assessment of Extended/Marginal Donor Lung for Transplant
- Weblink to trial
- Principal investigator: Bryan Whitson, MD, PhD
- Overview: This multicenter study is evaluating the safety and efficacy of ex vivo lung perfusion (EVLP) using the XVIVO Perfusion System (XPS™). Human donor lungs that do not meet the standard clinical criteria for donor lung utilization but fit into the study inclusion criteria will be re-assessed by the transplant team. The lungs will then be physiologically assessed during ex vivo perfusion using Steen solution with the addition of methylprednisolone, heparin and antibiotics. EVLP can increase the number of lungs available for transplantation and assure good organ quality for transplantation
Novel Markers of Human Lung Disease
Study title: Identification of Novel Markers of Human Lung Disease
- Weblink to trial
- Principal investigator: Megan Ballinger, PhD
- Overview: This study examines the role of specific cell types in regulating lung diseases such as interstitial lung disease, chronic obstructive pulmonary disease and pulmonary hypertension. Cells are isolated from a diseased lung post-transplantation and measured for a variety of parameters including production of cellular mediators, expression of genes important in signal transduction pathways, functionality of cells, viability and proliferation. Data collection from these cells will provide essential information regarding cellular dysfunction and dysregulation during lung disease and will enable the development of novel therapeutics
