March 7, 2016 updated by: Janssen Infectious Diseases BVBA

A Phase 3, Multicenter, Open-Label, Single-Arm Study to Investigate the Efficacy and Safety of a 12-Week Regimen of Simeprevir in Combination With Sofosbuvir in Treatment-Naïve or -Experienced Subjects With Chronic Genotype 1 Hepatitis C Virus Infection and Cirrhosis

The purpose of the study is to investigate the efficacy and safety of 12 weeks of simeprevir (150 mg qd) in combination with sofosbuvir (400 mg qd) in chronic hepatitis C virus (HCV) genotype 1 infected men and women with cirrhosis who are HCV treatment-naïve or treatment-experienced.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a open-label (all people know the identity of the intervention), single arm, multicenter study. The study will consist of a screening phase up to 4 weeks, open-label treatment phase of 12 weeks, and post-treatment follow up phase up to 24 weeks after end of treatment. Approximately 100 participants will receive 150 mg simeprevir in combination with 400 mg sofosbuvir once dailyfor 12 weeks. Safety evaluations will include assessment of adverse events, clinical laboratory tests, vital signs, and physical examination. The maximum study duration for each participant will be approximately 40 weeks.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants With a Sustained Virologic Response (SVR) 12 Weeks After the Actual End of Treatment (EOT)
Time Frame: Week 24
Participants with hepatitis C virus (HCV) ribonucleic acid (RNA) less than (<) 25 international unit per milliliter (IU/mL) (detectable or undetectable) at 12 weeks after the actual end of treatment.
Week 24

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants With a Sustained Virologic Response (SVR) 4 Weeks After the Actual End of Treatment (EOT)
Time Frame: Week 16
Participants with hepatitis C virus (HCV) ribonucleic acid (RNA) less than (<) 25 international unit per milliliter (IU/mL) (detectable or undetectable) at 4 weeks after the actual end of treatment.
Week 16
Percentage of Participants With a Sustained Virologic Response (SVR) 24 Weeks After the Actual End of Treatment (EOT)
Time Frame: Week 36
Participants with hepatitis C virus (HCV) ribonucleic acid (RNA) less than (<) 25 international unit per milliliter (IU/mL) (detectable or undetectable) at 24 weeks after the actual end of treatment.
Week 36
Percentage of Participants With On-treatment Virologic Response
Time Frame: Week 2, 4 and End of Treatment (Week 12)
On-treatment virologic response was determined by HCV RNA results satisfying a specified threshold. <LLOQ undetectable was considered as threshold at any time point. The LLOQ value is 25 IU/mL. EOT=End of Treatment.
Week 2, 4 and End of Treatment (Week 12)
Percentage of Participants With On-treatment Failure
Time Frame: Week 12
On-treatment failure is defined as participants who do not achieve SVR12 and with confirmed detectable HCV RNA at the actual end of study drug treatment.
Week 12
Percentage of Participants With Viral Breakthrough
Time Frame: Up to End of Treatment (Week 12)
Viral breakthrough was defined as confirmed greater than (>) 1 log10 increase in HCV RNA from nadir or confirmed HCV RNA >100 IU/mL in participants who had previously achieved HCV RNA < LLOQ (25 IU/mL).
Up to End of Treatment (Week 12)
Percentage of Participants With Viral Relapse
Time Frame: During the Follow-up (Week 24)
Viral relapse was defined as participants who did not achieve SVR12 and had HCV RNA < LLOQ (25 IU/mL) undetectable at EOT and had HCV RNA >= LLOQ (25 IU/mL) during the follow-up period.
During the Follow-up (Week 24)
Change From Baseline in Hepatitis C Symptom and Impact Questionnaire Version 4 (HCV-SIQv4) Overall Body System Score (OBSS) up to Follow-up Week 12
Time Frame: Baseline, Week 4, Week 12 and Follow-Up Week 12
The HCV-SIQv4 OBSS was a self-administered questionnaire that contained 33 items: 29 questions developed to assess severity or frequency of symptoms associated with HCV or its treatment, 3 questions regarding the impact of symptoms on work/school attendance, and 1 question regarding the impact of symptoms on daily activities. A symptom severity score (the mean of responses to the 29 symptom items); each symptom score was transformed to have a range from 0 to 100 (most severe). Higher HCV SIQv4 scores indicates worse symptom severity, more time missed from work/school, and more impairment in daily activities, respectively.
Baseline, Week 4, Week 12 and Follow-Up Week 12
Change From Baseline in Fatigue Severity Score (FSS) up to Follow-up Week 24
Time Frame: Baseline, Week 12, Follow-up Week 12 and 24
The FSS was a self-administered questionnaire with 9 items developed to assess disabling fatigue that has been used extensively in studies of chronic HCV infection. Item responses were measured on a 7-point Likert scale ranging from strongly disagree (1 point) to strongly agree (7 points). The 9 items were averaged to produce a total score; a lower total score indicates less severe fatigue. FSS scores have a range from 1 to 7 where higher scores indicate more severe fatigue.
Baseline, Week 12, Follow-up Week 12 and 24
Percentage of Participants With Depression by Using Center for Epidemiologic Studies Depression Scale (CES-D)
Time Frame: Baseline, Week 12, Follow-up Week 12 and 24
The CES-D Scale assessed how often during the past week participants experienced 20 symptoms commonly associated with major depression. The CES-D scores range from 0 (no symptoms) to 60 (all 20 symptoms most or all of the time during the past 5 to 7 days). The CES-D scores between 16 and 23 points indicate mild to moderate depressive illness while CES-D scores >=23 indicate probable major depressive illness.
Baseline, Week 12, Follow-up Week 12 and 24
Change From Baseline in EuroQol 5 Dimension Questionnaire (EQ-5D) up to Follow-up Week 24
Time Frame: Baseline, Follow-up Week 12 and 24
The EQ-5D questionnaire was a brief, generic health-related quality of life (HRQOL) assessment that could also be used to incorporate participant preferences into health economic evaluations. The EQ-5D questionnaire assessed HRQOL in terms of degree of limitation on 5 health dimensions (mobility, self-care, usual activities, pain/discomfort, anxiety/depression) and as overall health using a "thermometer" visual analog scale with response options ranging from 0 (worst imaginable health) to 100 (best imaginable health).
Baseline, Follow-up Week 12 and 24
Number of Participants Not Achieving SVR Showing Emerging Mutation at Time of Failure in HCV NS3/4A Sequence and NS5B up to Follow-up Week 24
Time Frame: Baseline, Day 3, Week 1, 2, 3, 4, 8, 12, Follow-up Week 4, 12 and 24
Sequencing of the HCV nonstructural protein 3/4A (NS3/4A) and nonstructural protein 5B (NS5B) genes was done to identify pre-existing sequence polymorphisms and characterize emerging HCV viral variants in participants not achieving SVR. Sequencing data is available for 16 participants.
Baseline, Day 3, Week 1, 2, 3, 4, 8, 12, Follow-up Week 4, 12 and 24
