Study summary

This study will determine if primary graft dysfunction (which causes low blood oxygen levels and fluid or inflammation in the lungs) after lung transplant can be prevented through the use of the study drug (IL-1 receptor antagonist, Anakinra). In this study, lung transplant participants who are randomized to the treatment group will have the study drug injected into the solution that their donor lungs are kept in prior to transplant.

Read the detailed description

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 have one dose of the study drug, Anakinra, injected into the perfusion solution that their donor lungs are kept in just prior to lung transplant. Both groups will receive standard lung transplant care after implantation.
