SRL (Sirolimus) Withdrawal

SRL minimization will be performed if clinically, biochemically and histologically stable. Patients entering the minimization phases will be reduced every month by 50% of total dose of Sirolimus until they reach .5mg daily for one month. Then .5 mg every other day, then twice weekly, the once weekly dosing. This should take approximately 6 month to complete minimization. Liver function tests will be monitored every 2 weeks. For any patient developing liver dysfunction, liver biopsy will be performed. Patients will then be completely withdrawn and followed post-withdrawal for 12 months.
