  • Adult, Older adult

Study population: living donor liver transplant (LDLT) recipients with recurrent HCV infection, participants were categorized to three groups according to AVT. Group one received pegylated interferon (Peg IFN-α 2a) and ribavirin (RBV) , group two received the direct antiviral agent (DAA) sofosbuvir plus RBV and group three received daclatasvir, sofosbuvir (other DAAs) plus RBV each group was further subdivided according to primary immunosuppression (CsA or Tac)

About this study

Official title: The Effect of Cyclosporine A Versus Tacrolimus on the Response to Antiviral Treatment After HCV Genotype -4 Recurrence in Recipients of Living Donor Liver Transplantation

Background and Aim: The immunosuppression influence on the response to antiviral therapy (AVT) for recurrent hepatitis C virus (HCV) infection in liver transplant (LT) recipients remains controversial, especially for the rarely investigated genotype 4.This study aims to compare the effects of the two widely used calcineurin inhibitors(CNIs)(Cyclosporine A (CsA) and tacrolimus (Tac)) on the therapeutic response to different AVT regimens. Method: In126 living donor liver transplant (LDLT) recipients with recurrent HCV infection, participants were categorized to three groups according to AVT. Group one received pegylated interferon (Peg IFN-α 2a) and ribavirin (RBV) (n= 44), group two received the direct antiviral agent (DAA) sofosbuvir plus RBV (n=52) and group three received daclatasvir, sofosbuvir (other DAAs) plus RBV(n=30) each group was further subdivided according to primary immunosuppression (CsA or Tac). The sustained virological response (SVR) and relapse rates were considered the primary therapeutic outcomes of AVT. The virological response guided therapy end points for AVT were considered the secondary outcomes.

Questions about this trial

What is this clinical trial studying?

An observational study of Liver Transplantation, run by Ain Shams University.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 0 inclusion and 21 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 11 Sep 2018. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

sustained virological response (time frame: 24 weeks for group I and 12 weeks for group II and III). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Sep 2018.
