A Study of Pharmacokinetics, Efficacy, Safety, Tolerability, of the Combination of Simeprevir (TMC435), Daclatasvir (BMS-790052), and Ribavirin (RBV) in Patients With Recurrent Chronic Hepatitis C Genotype 1b Infection After Orthotopic Liver Transplantation

Phase 2CompletedNCT01938625

Janssen R&D Ireland35 enrolled

Overview

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.

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

SimeprevirDRUG

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.

DaclatasvirDRUG

Participants will receive 60 milligram tablet of daclatasvir orally once daily for 24 weeks.

RibavirinDRUG

Participants will receive 5 or 6 tablets of 200 milligram of ribavirin orally twice a day with food for 24 weeks.

CyclosporineDRUG

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.

TacrolimusDRUG

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.

Eligibility

Sex: ALLMin age: 18 Years

Medical Language ↔ Plain English

Inclusion Criteria: * Liver transplant between 6 months and 10 years prior to the screening visit * Hepatitis C virus (HCV) genotype 1 subtype b infection confirmed at screening * Screening HCV ribonucleic acid level greater than 10,000 IU/mL * HCV treatment-naïve participants must not have received post orthotopic liver transplant treatment with any approved or investigational drug for the treatment of HCV * Receiving stable immunosuppressant therapy (ie, no change in dose in the last month) with cyclosporine (only allowed in Part 1) or tacrolimus for more than 3 months prior to the screening visit Exclusion Criteria: * Evidence of acute or chronic hepatic decompensation after the liver transplantation (including ascites, bleeding varices or hepatic encephalopathy) * Any liver disease of non-HCV etiology, including current evidence of graft rejection except the presence of liver steatosis * Any other clinically significant disease that in the opinion of the investigator would be exacerbated by the known effects of ribavirin * Coinfection with HCV of another genotype than genotype 1b, HIV type 1 or 2 (positive HIV-1 or HIV-2 antibodies test at screening), and hepatitis B virus (hepatitis B surface antigen positive) * Multi-organ transplant that included heart, lung, pancreas, or kidney

Outcomes

Primary Outcomes

Percentage of Participants With Sustained Virologic Response 12 Weeks After the End of Treatment (SVR 12)

Participants were considered to have achieved SVR12 if hepatitis C virus ribonucleic acid (HCV RNA) levels were less than (\<) 25 international unit per milliliter (IU/mL) detectable or undetectable at 12 weeks after the end of treatment.

Time frame: Week 36

Secondary Outcomes

Percentage of Participants With Sustained Virologic Response 4 Weeks After the End of Treatment (SVR 4)

Participants were considered to have achieved SVR4 if HCV RNA levels were (\<) 25 IU/mL detectable or undetectable at 4 weeks after the end of treatment.

Time frame: Week 28

Percentage of Participants With Sustained Virologic Response 24 Weeks After the End of Treatment (SVR 24)

Participants were considered to have achieved SVR 24 if hepatitis C virus ribonucleic acid (HCV RNA) levels were (\<) 25 IU/mL detectable or undetectable at 24 weeks after the end of treatment.

Time frame: Week 48

Percentage of Participants With HCV RNA (< 25 IU/mL Undetectable) and HCV RNA < 25 IU/mL Detectable

Percentage of participants with detectable and undetectable HCV RNA (\<) 25 IU/mL during treatment at Weeks 2,4, 12, and 24 were reported.

Time frame: Weeks 2, 4, 12, and 24

Percentage of Participants With HCV RNA (<) 100 IU/mL at Week 4

Percentage of participants with HCV RNA (\<) 100 IU/mL at week 4 were reported.

Number of Participants With On-Treatment Failure

On-treatment failure is defined as participants who did not achieve SVR12 and with confirmed detectable HCV RNA at the actual end of treatment. This was to include participants with: 1) Viral breakthrough, defined as a confirmed increase of greater than (\>)1 log10 in HCV RNA from nadir, or confirmed HCV RNA of \>100 IU/mL in participants whose HCV RNA had previously been \<lower limit of quantification (LLOQ) while on treatment; 2) Other with confirmed detectable HCV RNA at the actual end of treatment (example, completed, discontinued due to adverse events (AEs), withdrawal of consent).

Time frame: Up to Week 24 after actual EOT (week 24)

Number of Participants With Viral Breakthrough

Viral breakthrough is defined as a confirmed increase of \>1 log10 IU/mL in HCV RNA level from the lowest level reached, or a confirmed HCV RNA level of \>100 IU/mL in participants whose HCV RNA levels had previously been below the limit of quantification (\<25 IU/mL detectable) or undetectable (\<25 IU/mL undetectable) while on study treatment.

Time frame: Up to week 24
