Professor Stig Steen Described successful reconditioning and transplantation of 6 out of 9 donor lungs deemed unusable for transplant. All 6 recipients survived the first 3 months 4 of the 6 were alive and well 12 months after transplant Ann Thorac Surg. 2009 Jan;87(1):255-60.
Establishing an EVLP Programmein Newcastle • Ethics committee approval • Hospital procedure approval • Non-clinical pilot phase • Consent of waiting list patients • Education of the transplant team • Manpower and logistics • Deciding the technique • Agreeing acceptance criteria

Potential Impact of EVLP • Increased offering of donor organs • Increased lung transplant activity • Reduced waiting list mortality • Reduced incidence of severe PGD? • Improved longterm outcomes? • Less rejection? • Less infection? • Platform for therapeutics

Study Details • Design: • Non-randomised, non-inferiority observational study with an adaptive design • Funders: • NIHR Health Technology Assessment Programme and CF Trust • Sponsor: • The Newcastle upon Tyne Hospitals NHS Foundation Trust
Primary Objective: To compare survival during the first 12 months after lung transplantation in recipients of EVLP assessed and reconditioned donor lungs (treatment group) compared to that of recipients of standard donor lungs (control group), in order to assess whether survival in the EVLP treatment group over that period is non-inferior to that in the standard control group.
Secondary Objectives: • Assess early clinical outcomes • Measure quality of life (QOL) • To determine if EVLP is a cost-effective • Explore patients attitudes to and experiences of EVLP • To collect biological samples during EVLP reconditioning to support parallel mechanistic studies
