Summary

The purpose of the study is to evaluate effect of steady-state (when the amount of drug administered (in a given time period is equal to the amount of drug eliminated in that same period) of simeprevir and daclatasvir on the steady-state pharmacokinetics (what a medication does to the body) of cyclosporine (applicable to Part 1 only) and tacrolimus when administered as a combinational regimen in post-orthotopic liver transplantation (OLT) participants with recurrent hepatitis C virus (HCV) genotype 1b infection and effectiveness of a 24-week treatment regimen containing simeprevir, daclatasvir, and ribavirin (RBV) with respect to the proportion of HCV genotype 1b infected post-OLT participants achieving sustained virologic response 12 weeks after end of treatment.

Detailed description

This is an open-label (all participants of this study know the identity of the intervention) and multicenter (study conducted at multiple sites) study. This study will be conducted in 2 parts. Both the parts of the study will consist of screening phase (4 weeks), treatment period (24 weeks), and a post-treatment follow-up (24 weeks). A total of 30 participants will be enrolled in Part 1 and Part 2 of the study. A minimum of 9 participants were planned to receive cyclosporine as stable immunosuppressant therapy and a minimum of 9 participants were planned to receive tacrolimus as stable immunosuppressant therapy during Part 1. All participants will be receiving tacrolimus as stable immunosuppressant therapy during Part 2. In Part 1 of the study, participants with Metavir score of F1-F2, will receive a combination of study drugs - simeprevir, daclatasvir, and ribavirin for 24 weeks. In Part 2 of the study, participants with Metavir score F1-F4 will receive a dosing regimen of study drugs based on the data from Part 1 of the study. Safety evaluations will include assessments of adverse events, clinical laboratory tests, urinalysis, electrocardiogram, vital signs, and physical examination. The total study duration for each participant will be approximately 52 weeks.

Interventions

Type	Name	Description
DRUG	Simeprevir	Participants will receive 150 milligram capsule of simeprevir orally (by mouth) once daily with food for 24 weeks. In Part 1, if simeprevir pre-dose plasma concentration is greater than 7,300 nanogram per milliliter (ng/mL), participants will receive simeprevir 150 milligram capsule orally every other day to complete 24 weeks of treatment.
DRUG	Daclatasvir	Participants will receive 60 milligram tablet of daclatasvir orally once daily for 24 weeks.
DRUG	Ribavirin	Participants will receive 5 or 6 tablets of 200 milligram of ribavirin orally twice a day with food for 24 weeks.
DRUG	Cyclosporine	Participants will receive cyclosporine as one of the stable immunosuppressant therapy (no change in dose in the last month) for more than 3 months prior to the screening visit. Cyclosporine will be administered as per the manufacturer's prescribing information for 24 weeks.
DRUG	Tacrolimus	Participants will receive tacrolimus as one of the stable immunosuppressant therapy (no change in dose in the last month) for more than 3 months prior to the screening visit. Tacrolimus will be administered as per the manufacturer's prescribing information for 24 weeks.
