Healthy volunteers: no

Brief summary:
This is an investigator initiated study at the University of California, Los Angeles (UCLA) funded by Novartis looking at using a combination of immunosuppressive drugs in liver transplant patients that are at risk of developing kidney problems. Kidney problems following liver transplants is the most problematic issue facing liver transplant patients today.

This study will generate information in this area of high unmet medical need utilizing basiliximab and Myfortic and using a reduced dose of tacrolimus, one of the current standard of care medications, after kidney function has normalized.

Detailed description:
Since basiliximab works on the same receptor system as tacrolimus and has not been shown to cause significant adverse effects, such as nephrotoxicity or the cytokine release syndrome, the investigators are proposing induction therapy with basiliximab in liver transplant patients with concomitant preoperative renal dysfunction. This will combat acute rejection and allow the delay of tacrolimus therapy until post-operative day #7. The delay in tacrolimus therapy should allow renal function to improve and reduce the chance of continued renal dysfunction. Also, the addition of basiliximab to the immunosuppressive regimen should allow for a reduction in tacrolimus dose (normal tacrolimus concentrations at UCLA are 7-10ng/mL. Our goal will be 3-5ng/mL) in the immediate post-transplant period thereby reducing the chance of acute and long-term efficacy-limiting adverse effects associated with the tacrolimus while maintaining adequate immunosuppression to reduce acute rejection episodes. This would be the most convincing prospective randomized study utilizing basiliximab as a renal sparing agent in liver transplantation.

Objectives Primary objectives

• To evaluate renal recovery/ function following OLT in patients undergoing orthotopic liver transplant at 6 and 12 months post-transplant.

Secondary objectives (comparing the two treatment arms)

* To determine the tolerability and adverse event profile during the first year post-transplant.
* To determine incidence and severity acute rejection episodes
* To determine the incidence of death and/or graft failure within the first year post-transplant

Study design The study is a single center prospective randomized trial wherein the investigators will have two groups. Patients will be screened and eligible patients will be enrolled pre-transplant. Patients will then be randomized at time of transplant to either the control or treatment arm. Post transplant laboratory data (chemistry, tacrolimus level and liver function tests) will be collected on a daily basis. For the duration of the patients' hospital stay (average 2-3 weeks). This will provide the early data set for early post operative results. Patients will subsequently be followed on a weekly outpatient basis upon discharge as per protocol. During these visits, laboratory data (chemistry, tacrolimus level and liver function tests) are also collected and will provide the continued flow of data for our follow up analysis. Any evidence of rejection will prompt treatment with rescue therapy and if necessary disenrollment from the study.
