Phase 2 Study of Ex-vivo Perfusion and Ventilation of Lungs to Assess Transplant Suitability - Full Text View

Purpose

The purpose of this research study is to perfect the technique of EVLP and learn about the safety of transplanting lungs that have been ventilated (attached to a breathing machine or ventilator to deliver oxygen) and perfused with a lung perfusion solution (Steen solution™, made by Vitrolife). This ventilation and perfusion will be done outside the body (ex-vivo) in a modified cardiopulmonary bypass circuit (the kind of device used routinely during most heart surgeries). The purpose of performing ex-vivo lung perfusion and ventilation (EVLP) is to learn how well the lungs work, and whether they are likely safe to transplant.

Primary Outcome Measures:

30 Day Mortality [ Time Frame: 30 Days ]
The primary objective evaluated for this study is recipient mortality at 30 days post transplant. 30 day mortality is used as a standard research assessment to evaluate post transplant outcomes.

Secondary Outcome Measures:

Primary Lung Graft Dysfunction (PGD) [ Time Frame: 24 and 72 hours post transplant. ]
Primary Lung Graft Dysfunction (PGD) is an indicator for significant morbidity and mortality after lung transplantation. PGD at 24 and 72 hours post LTX are secondary objectives.
ICU Length of Stay [ Time Frame: Time to Discharge. ]
The length of ICU stay is another standard research and clinical outcome assessment post transplant and has been selected as a secondary objective.
Day 7 Ventilator/ECMO Status [ Time Frame: 7 Days Post Transplant. ]
7 days ventilator or extra-corporeal membrane oxygenator (ECMO free are being evaluated as secondary objectives.
Recipient mortality at 12 months. [ Time Frame: 12 months ]
Recipient mortality at 12 months post transplant is being evaluated as a secondary objective.

Arms	Assigned Interventions
Experimental: EVLP with STEEN Solution™ The perfusion of the lungs will be performed using STEEN Solution™ and then physiologically assessed. Lungs deemed suitable will be transplanted after Ex-vivo Perfusion w/ STEEN Solution™.	Device: Steen Solution™ This solution is a buffered dextran and albumin-containing extracellular perfusate with an optimal colloid osmotic pressure developed specifically for extra-corporeal perfusion of lungs. After EVLP, lungs will be cooled in the circuit to room temperature, then flushed with cold Perfadex™ and taken to UNCH where they will have an ex-vivo CT scan. Lungs determined suitable will be offered to consented patients at UNC Hospitals based on Lung Allocation Score. Lungs not considered for transplantation may be subjected to different experiments but are not to be a part of this research study. In summary, lungs with good and stable function during EVLP with Steen Solution™ will be transplanted into recipients as per current clinical practice.
Active Comparator: Conventional Lung transplant No experimental procedures will be carried out. Lungs from conventional brain-dead organ donors will be used for transplant.	Other: Conventional Lung Transplant No experimental procedures will be carried out. Lungs from conventional brain-dead organ donors will be used for transplant.
