Delayed Infusion of DCreg in Living Donor Liver Transplantation

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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 who are between 1 and 3 years after transplantation and meet specific criteria (no positive crossmatch, no clinically treated rejection within 2 years preceding enrollment, permissive liver function tests (LFTs) within 30 days preceding enrollment, no prior liver biopsy showing significant fibrosis or ductopenia\*) will be enrolled and will undergo a protocol liver biopsy unless they have had a permissive liver biopsy\*\* within 90 days of anticipated immunosuppression weaning. Those patients with permissive liver biopsy\*\* will then receive a single infusion of donor-derived DCreg and will remain on their current standard of care (SOC) immunosuppression. One week after DCreg infusion, immunosuppression weaning will be initiated. Recipients will be slowly weaned off immunosuppression. 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 will undergo a liver biopsy at the end of the study. \* Permissive LFTs are defined as ALT, AST and total bilirubin \< 2.5 times the upper limit of normal. \*\*A permissive biopsy is based on 2016 Comprehensive Update of the Banff Working Group on Liver Allograft Pathology (the criteria detailed in Table 8, Demetris et al. 2016).
