*Purpose: As interest in transplantation of Hepatitis C virus (HCV)-viremic kidneys into HCV-uninfected (HCV+ to HCV– KT) recipients increases, understanding clinical outcomes beyond HCV clearance with direct-acting antivirals is important. We report the one-year outcomes of the seven-center MYTHIC (Multi-center studY to Transplant Hepatitis-C InfeCted Kidneys) trial.
*Methods: Donors were HCV RNA positive, had any HCV genotype, with KDPI < 85. The 30 KT recipients were treated with Glecaprevir-pibrentasvir (G/P) for 8 weeks, starting 2-5 days post-KT. We assessed the following 1 year post transplant: HCV virologic status, Cytomegaloviurs (CMV), and polyoma virus (BK) infection, transplant rejection, graft function, and patient survival. We performed a comparison of time-to-transplant with recipients of non-HCV infected kidneys derived from UNOS and matched based on a multivariate risk score.
*Results: Seventy-six patients were consented for evaluation, 12 were excluded, and of 64 eligible patients, 30 underwent kidney transplant from HCV-viremic donors after a median of 6.3 weeks (IQR, 1.9-10.1). Patients enrolled in the MYTHIC trial were significantly more likely to receive a kidney transplant compared to risk-score matched UNOS comparators (N=642) (Figure). All 30 participants achieved durable HCV clearance and no patient developed clinically significant liver disease. There were 9 cases of detectable CMV viremia in the first year post-transplant, with 4 cases having > 1000 IU/mL. There were 4 cases of BK viremia > 1000 IU/mL. One year survival was 93%; there were two deaths after HCV cure (Staph aureus bacteremia and unexplained death at home). There were 3 cases of biopsy-confirmed acute rejection. One year graft function among the 28 surviving patients was excellent (mean serum creatinine 1.27mg/dL, SD 0.41).
*Conclusions: One year findings from the first multicenter standardized trial of pre-emptive G/P after HCV+ to HCV- KT demonstrate that this approach is highly effective, with excellent patient outcomes and shortened waitlist time to transplant.
