Clinical Trial Summary

Phase I/II, single center, prospective, open-label, non-controlled, non-randomized, interventional, cohort study in which low risk living donor liver transplant (LDLT) recipients will receive a single infusion of donor-derived DCreg 1 week prior to transplantation. All patients will be maintained on MPA and Tacrolimus (Tac) for the 1st 6 months after transplantation. At that time point, recipients meeting specific criteria will be slowly weaned off MPA per standard of care over a period of 6 months. Participants will then be evaluated for TAC weaning at 1 yr after transplantation. Those who meet specific criteria be weaned off Tac over 6 months . Successfully weaned participants who remain rejection-free will undergo 3 years of follow-up after the last dose of immunosuppression.


Clinical Trial Description

Phase I/II, single center, prospective, open-label, non-controlled, non-randomized, interventional, cohort study in which low risk living donor liver transplant (LDLT) recipients will receive a single infusion of donor-derived DCreg with concurrent mycophenolic acid (MPA) therapy (1/2 dose) 1 week prior to transplantation. All patients will be maintained on MPA and Tacrolimus (Tac) for the 1st 6 months after transplantation. At that time point, recipients meeting specific criteria (no rejection and permissive liver function tests (LFTs)) will be slowly weaned off MPA per standard of care over a period of 6 months. Participants will then be evaluated for TAC weaning at 1 yr after transplantation. Those who meet the criteria of no rejection and permissive LFTs will undergo a protocol liver biopsy and proceed to Tac weaning over 6 months if liver biopsy is permissive. Successfully weaned participants who remain rejection-free will undergo 3 years of follow-up after the last dose of immunosuppression. They will undergo a liver biopsy at 1 yr and 3 yrs after immunosuppression withdrawal. Participants who are removed from the study protocol at any time will return to standard of care but will continue to be followed by the study team and may undergo a liver biopsy at the end of the study (4.5 yrs after transplantation). For subjects who return to standard of care (on immunosuppression at end of study), the year 4.5 biopsy will be optional. ;
