Safety and Efficacy of Treprostinil (Remodulin®) In Reducing Ischemia-Reperfusion Injury During Kidney Transplantation

• Status: Not yet recruiting
• Trial end date: 2022-06-30
• Target enrollment: 0
• Participant gender: All

Summary

The objectives of this study are to test the preliminary safety and efficacy of a two-day peri-operative course of treprostinil in reducing ischemia-reperfusion injury in adult patients receiving a deceased donor kidney transplantation. Treprostinil, a prostacyclin analog, is expected to facilitate the restoration of blood supply to the revascularized kidney graft via its vasodilatory actions, well characterized protective effects, and longer elimination half-life. These properties and actions of treprostinil make it a strong drug candidate to reduce kidney graft dysfunction during kidney transplantation. An anticipated 20 participants undergoing deceased donor kidney transplant will be hospitalized and intensively monitored during an entire two-day Treatment Phase. An IV infusion using a dedicated central venous line will be used to administer treprostinil commencing approximately 2-3 hours before transplantation of the kidney graft and will continue for approximately 48 hours after completion of the transplant surgery. The primary endpoints include the safety and efficacy of treprostinil, with secondary endpoints including the evaluation of both biochemical and clinical endpoints post-transplantation.
