After being informed about the study and potential risks, all patients giving written consent who undergo a lung transplant will be randomized in a 1:1 ratio to either the treatment or control group. Patients randomized to the treatment group will receive one dose of the study drug, Etanercept, via subcutaneous injection just prior to the lung transplant. Patients randomized to the control group will not receive Etanercept. Both groups will receive standard lung transplant care after implantation.
