简要总结
This project is focused on helping one of the most vulnerable patient populations in medicine, patients with end-stage chronic lung disease. Lung transplantation is the only cure for end-stage lung disease, however, due to the persistent shortage of donor organs, either due to low organ donation rates or unacceptable organs, only a minority of patients receive desperately needed lung transplants. Currently less than 30% of potential donated thoracic organs are being used for transplantation. The major causes for under utilization of donor thoracic organs are injury sustained by the lungs in trauma or emergency resuscitation or lungs that come from donors who are pronounced dead due to cardiac arrest (known as DCD donors). It has been hypothesized that these injuries may be reversible or repairable if there was an opportunity to evaluate and repair these organs outside of the body (ex-vivo), prior to transplantation. In fact, studies have shown that the use of normothermic Ex-Vivo Lung Perfusion (EVLP) has increased the rate of donor organ utilization at centers that have adopted the technology.
Current methodology for all clinically available EVLP devices uses Positive Pressure Ventilation (PPV). Researchers at the University of Alberta (UofA), however, have developed an EVLP device that will apply Negative Pressure Ventilation (NPV) to the lungs, as opposed to PPV, which is the most ideal mimicry of native lung physiology. The objective of this early feasibility safety trial is to show that the UofA developed NPV-EVLP device is acceptable in evaluating and improving the quality of marginal donor lungs compared to currently used EVLP devices, ultimately allowing for these types of donor lungs to be safely transplanted into patients on the lung transplant recipient waitlist.

结局指标
主要结局
Patient survival post transplantation at Day30
时间窗: Day30 post-Transplant
The primary end point is a co-primary endpoint comparing patient survival rates post transplantation at Day30 (Outcome 1) and rates of Primary Graft Dysfunction (PGD) Grade 3 in the first 72 hours (Outcome 2) with success measured only if both endpoints are met.
