상세 설명

This is a Phase 2, multicenter (when more than one hospital or medical school team work on a medical research study), partially randomized (study drug is assigned by chance), and open-label (all people know the identity of the intervention) study to explore the safety and efficacy of simeprevir plus sofosbuvir. The study will consist of a screening period (Screening and Baseline), followed by randomization. First 33 non-cirrhotic participants will be randomly assigned in a ratio of 1:1:1 into 1 of 3 treatment arms, and up to 12 cirrhotic participants will be enrolled and all will be assigned to Arm 3. All participants in treatment Arms 1 and 2 will return for treatment visits at Weeks 1, 2, 4, 8, 12, and post-treatment follow-up visits on Weeks 16 and 24. All participants in treatment Arm 3 will return for treatment visits at Weeks 1, 2, 4, 8, 12, 16, 20, and 24, and post-treatment follow-up visits on Weeks 28 and 36. Participants will receive simeprevir plus sofosbuvir and RBV for a 12-week treatment period in Arm 1, simeprevir plus sofosbuvir without RBV for a 12-week treatment period in Arm 2 and simeprevir plus sofosbuvir for a 24-week treatment period in Arm 3. Efficacy will primarily be evaluated by SVR12. Participants' safety will be monitored throughout the study.

Weeks 2, 4, 8 and 12 (for all treatment arms) and Weeks 16 20, and 24 (for Arm 3)
Percentage of Participants With Viral Breakthrough
기간: Baseline up to Week 24 (for Arms 1 and 2) and Baseline up to Week 36 (for Arm 3)
Viral breakthrough is defined as confirmed greater than (>) 1.0 Log10 increase in HCV RNA from nadir or confirmed HCV RNA >100 IU/mL in participants who had previously achieved HCV RNA <15 IU/mL.
Baseline up to Week 24 (for Arms 1 and 2) and Baseline up to Week 36 (for Arm 3)
Percentage of Participants With Viral Relapse
기간: Baseline up to Week 24 (for Arms 1 and 2) and Baseline up to Week 36 (for Arm 3)
Participants will be considered to have viral relapse if they meet the following conditions: 1) HCV RNA <15 IU/mL (undetectable) at the end of treatment; and 2) HCV RNA greater than or equal to (>=) 15 IU/mL during the post-treatment follow-up period.

기간: Baseline, Week 24 (for Arms 1 and 2) and Week 36 (for Arm 3)
The HCV-SIQv4 is a self-administered questionnaire containing 33 items classified as 3 categories of scores: 1) Symptom severity score (sum of responses to 29 questions to assess severity or frequency of symptoms associated with HCV or its treatment; 2) Time missed from work/school (sum of responses to 3 questions regarding the impact of symptoms on work/school attendance); 3) Daily activity score (response to 1 question regarding the impact of symptoms on daily activities). Higher HCV SIQv4 scores indicate worse symptom severity, more time missed from work/school, and more impairment in daily activities, respectively. The total score is the sum of scores of these 3 categories.
Baseline, Week 24 (for Arms 1 and 2) and Week 36 (for Arm 3)
Change From Baseline in EuroQol 5 - Dimension (EQ-5D) Questionnaire Score at Weeks 4, 8, 12, 16, 20, 24 (for all treatment arms) and Week 36 (for Arm 3)
기간: Baseline, Weeks 4, 8, 12, 16, 20, 24 (for all treatment arms) and Week 36 (for Arm 3)
The EQ-5D questionnaire is a brief, generic health-related quality of life assessment (HRQOL) that can also be used to incorporate participant preferences into health economic evaluations. The EQ-5D questionnaire assesses 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). Lower scores indicate worsening. EQ-5D scores include EQ-5D valuation index score (a weighted scoring of the 5 dimension scores with a possible range from 0 to 1), EQ-5D visual analog scale (VAS) is a 20 centimeter (cm) vertical VAS with scores ranging from 0 (worst imaginable health) to 100 (perfect health), and EQ5D descriptive system scores (five scores reflecting each of the 5 EQ-5D health dimensions ranging from 0 [no limitation] to 4 [incapacity]).
