RecruitingClinical trialProphylaxis With Direct-acting Antivirals for Kidney Transplantation From HCV-Infected Donors to Uninfected RecipientsThis study is being done to find out the best time to start medication for Hepatitis C Virus (HCV) in HCV-negative recipients of HCV-positive (HCV D+/R-) kidney transplants. Participants will be randomized into one of two groups: Arm 1 - Prophylaxis: This group will start the HCV medication before transplant and will take a shorter course of HCV medication for 2 weeks. Arm 2 - Transmit and Treat: This group will start the HCV medication after transplant and will take the full course (12 weeks) of HCV medication.
