简要总结
In this study, individuals without hepatitis C infection who are on the kidney transplant waitlist will receive a kidney from a deceased donor with hepatitis C infection and will be treated for hepatitis C at the same time. Treatment will include Grazoprevir (GZR) 100 mg/Elbasvir (EBR) 50 mg administered on-call to the operating room for the renal transplant procedure and continued for 12 weeks post-renal transplant.
详细描述
In this study, individuals without hepatitis C infection who are on the kidney transplant waitlist will receive a kidney from a deceased donor with hepatitis C infection and will be treated for hepatitis C at the same time. Hepatitis C treatment will include Grazoprevir (GZR) 100 mg/Elbasvir (EBR) 50 mg administered on-call to the operating room for the renal transplant procedure and continued for 12 weeks post-renal transplant. The donor hepatitis C genotype will be tested. If the donor has genotype 1a without resistance or genotype 1b treatment will remain GZR/EBR for 12 weeks. If the donor has genotype 1a with resistance variants, then Ribavirin will be added and treatment will be given for 16 weeks starting from the date ribavirin was added. If the donor has hepatitis C genotype 2 or 3, Sofosbuvir will be added and treatment will be for 12 weeks from the date Sofosbuvir was added.

- •Males who are not surgically sterile and are sexually active with female partner(s) of childbearing potential must agree to practice two effective forms of birth control (as outlined in the participant information and consent form) throughout the course of the study, starting with starting with Study Day 1 and for 30 days after stopping study drug, or for 6 months after stopping study drug if receiving ribavirin (RBV)
排除标准

结局指标
主要结局
Number of Participants With Grade 3 or Higher Treatment-related Adverse Events as US Department of Health and Human Services Common Terminology of Adverse Events (CTCAE) Version 4
时间窗: 12 weeks after transplant
Proportion of participants with grade 3 or higher treatment-related adverse events (AE) as assessed by US Department of Health and Human Services Common Terminology of AEs version 4. An AE is an unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medical treatment or procedure that may or may not be considered related to the medical treatment or procedure. Grade refers to the severity of the AE. The CTCAE displays Grades 1 through 5. Grade 3 Severe or medically significant but not life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; Grade 4 Life-threatening consequences; urgent intervention indicated. Grade 5 Death related to AE. The investigator will determine if the AE is related to the treatment.
