Brief Summary:
Sirolimus can be safely switched as early as 90 days after liver transplantation with excellent tolerability and amelioration of the calcineurin inhibitor toxicity that initiated the switch.

Drug Information available for: Sirolimus

Group/Cohort Intervention/treatment

Our experience with the use of Sirolimus is delineated below. About 15% to 20% of our patients are currently switched to Sirolimus.Indications for conversion from calcinurin inhibitors (CNIs) to Sirolimus more than 90 days post liver transplantation include:

  • CNI renal toxicity.
  • Hepatic fibrosis on biopsy.
  • CNI neurologic toxicity.
  • Post transplant diabetes. Any of the above 4 indications makes a patient a candidate for conversion from CNIs to Sirolimus at or > 90 days after liver transplantation.
Procedure: Liver biopsy
percutaneous liver biopsy

Primary Outcome Measures :
  1. The primary objective is that acute cellular rejection following a switch to sirolimus will be comparable to the historical rate at our center under calcineurin inhibitors of around 5% for post liver transplant recipients. [ Time Frame: 12 months ]

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population
post liver transplant patients taking calcineurin inhibitors (tacrolimus or cyclosporine) as anti-reject medication

Inclusion Criteria:

  1. Adult (18 years or older) patients undergoing liver transplantation at Thomas Jefferson University Hospital.
  2. Diagnosed with at least one of the following CNI side effects 90-180 days post transplantation:

    1. CNI renal toxicity. Any liver transplant recipient who has elevated creatinine level (greater than 1.4 mg/dl) and impaired creatinine clearance (MDRD) of 40-60 ml/minute or decreased by 15% compared to baseline in the setting of having a therapeutic CNI level, without suspicion of acute or chronic allograft rejection.
    2. Hepatic fibrosis on biopsy. Any patient who has fibrosis seen on liver biopsy with LFT's 2 times the upper normal limit.
    3. CNI neurologic toxicity. Any patient who has significant neurological side effects from CNIs. This will include the following: seizures not secondary to an epileptogenic focus or any metabolic derangement; alteration of speech ranging from aphasia to slurred speech; inability to be awake and alert.
    4. Post transplant diabetes. Any patient who has developed diabetes after transplant and in whom CNIs are thought to be contributing to poor glycemic control.
  3. Signed informed consent at approximately 90 -180 days post transplantation.

Exclusion Criteria:

  1. Invasive/surgical therapy within 2 weeks of the 90-180 day post transplantation conversion. (e.g. patients with T-tubes would not be eligible for the study because the T-tube removal will coincide with the conversion date).
  2. Open surgical wound at 90-180 days post transplantation.
  3. Acute cellular rejection during the first 90-180 days post transplantation.
  4. Re-transplants or multiple-organ transplants.
  5. Active infection.
  6. Pregnancy.
  7. Malignancy within 3 years prior to liver transplantation (except adequately treated basal cell carcinoma). Patients with HCC prior to transplant will not be excluded.
  8. Total cholesterol >300 mg/dl on medical treatment or triglycerides >150 mg/dl at 90-180 days post transplantation.
  9. White blood cell count <3,000/mm3 or platelet count <100,000/mm3 at 90-180 days post transplantation.
  10. Ascites.
  11. Patients on chemotherapy.
  12. Urine protein/creatinine ration > 0.5
