Trial Summary

What is the purpose of this trial?

The Transplanting Hepatitis C Kidneys into Negative KidnEy Recipients \[THINKER-NEXT\] study will include adult kidney transplant candidates without hepatitis C virus (HCV) infection on the transplant waiting list who will consent to kidney transplantation from a deceased donor infected with HCV, followed by treatment with a direct acting antiviral. The one-year allograft function and one-year risk of CMV infection will be compared between THINKER-NEXT kidney transplant recipients and matched recipients who received hepatitis C uninfected kidney transplants (these patients are called Transplant Cohort). The survival rate of patients opting-in for offers of kidneys from HCV-viremic donors will be compared to the survival rate of matched comparators from the kidney transplant waitlist who did not consent to receive offers of a HCV-viremic kidney. Lastly, renal pathologic findings will be compared among HCV-viremic donors and HCV-negative comparator donors.

Do I have to stop taking my current medications for this trial?

The trial does not specify if you need to stop taking your current medications, but you cannot participate if you are currently using amiodarone or dronedarone.

What data supports the idea that Hepatitis C Kidneys Transplantation for Kidney Failure (also known as: Epclusa, Epclusa, sofosbuvir/velpatasvir) is an effective treatment?

The available research shows that the drug sofosbuvir/velpatasvir is effective for kidney transplant patients who receive kidneys from donors with Hepatitis C. In a study, all patients who received this drug after their transplant had no detectable Hepatitis C virus in their blood after 12 weeks of treatment. This suggests that the drug is effective in preventing the spread of the virus from the donor kidney to the recipient. Additionally, the study found that the drug was safe, as none of the adverse events reported were related to the medication. This indicates that sofosbuvir/velpatasvir is both effective and safe for use in this context. ^{1 2 3 4 5}

What safety data exists for using Sofosbuvir/Velpatasvir in kidney transplants from HCV-positive donors?

A study evaluated the safety of Sofosbuvir/Velpatasvir in HCV-negative recipients receiving kidneys from HCV-positive donors. All 26 patients completed the 12-week treatment, with 100% achieving negative HCV RNA. Adverse events occurred in 57.7% of patients, including graft rejection (11.5%), delayed graft function (23.1%), and bleeding (11.5%), but none were related to the medication. Renal function remained stable, indicating the treatment was effective and safe. ^{1 3 4 5 6}

Is the drug Epclusa a promising treatment for kidney failure patients receiving a hepatitis C kidney transplant?

The research articles focus on sofosbuvir and daclatasvir, not Epclusa (sofosbuvir/velpatasvir). However, they show that sofosbuvir-based treatments are effective and safe for kidney transplant patients with hepatitis C. This suggests that Epclusa, which also contains sofosbuvir, could be promising for similar patients. ^{1 2 5 7 8}

Findings from Research

In a study of 19 kidney transplant recipients treated with sofosbuvir-daclatasvir, 100% achieved a sustained virological response 12 weeks after treatment, indicating the treatment's high efficacy against chronic hepatitis C virus (HCV) infection.

Patients also showed significant improvements in liver function, with notable decreases in liver enzyme levels (ALT and AST), and stable kidney function throughout the therapy, suggesting that the treatment is well-tolerated and safe for this population.

In a study of 6 male kidney transplant patients with hepatitis C, treatment with sofosbuvir and daclatasvir resulted in a 100% sustained virological response rate after 12 weeks, indicating high efficacy in clearing the virus.

The treatment was generally safe, with no serious adverse events reported, although two patients required a reduced dose of sofosbuvir due to elevated serum creatinine levels, suggesting careful monitoring of kidney function is necessary.

The sofosbuvir-velpatasvir regimen achieved a high sustained virological response (SVR12) rate of 94.2% in 1277 patients with chronic hepatitis C virus (HCV) infection, indicating its strong efficacy.

Adding ribavirin did not significantly improve SVR12 rates for HCV genotypes 1 and 2, but it did enhance the response for genotype 3 patients, suggesting that ribavirin may be beneficial for specific HCV genotypes.
