MeasureTime frameDescription
Mean Short Form-36 Questionnaire Scores for Groups A and B Over Time (Part 1)Baseline (Day 1), Week 24, Week 48, Week 72, and Week 96The Short Form-36 (SF-36) is a quality of life instrument consisting of a 36-item questionnaire. The SF-36 items were scored and transformed according to the SF-36 Health Survey Manual and Interpretation Guide. Summary scores for SF-36 dimensions (physical functioning, role functioning, bodily pain, general health, vitality, social functioning, mental health, health transition) as well as physical and mental summary measures were compiled after imputation of mean scores for missing items if more than 50% of dimension-related items were available. Scores for health transition ranged from 0 (worst) to 5 (best). Scores for all other dimensions ranged from 0 (worst) to 100 (best). The mean SF-36 scores are presented at Baseline (Day 1), Week 24, Week 48, Week 72 (for Groups A and B) and at Week 96 (for Group B). Lower score indicate worsening.
Mean Fatigue Severity Scale Scores for Groups A and B Over Time (Part 1)Baseline (Day 1), Week 24, Week 48 and Week 72, and Week 96The Fatigue Severity Scale (FSS) is an instrument consisting of 10 self-administered questions. The FSS items were scored by calculating the average response to all answered items (including the 9 questions and the fatigue symptoms). Each of the 9 questions had answers within a score range of 1-7. A score of 1 for any question indicates less fatigue in everyday life and a score of 7 indicates a higher likelihood of fatigue in everyday life. The mean FSS scores are presented at Baseline (Day 1), Week 24, Week 48 and Week 72 (for Groups A and B) and at Week 96 (for Group B).
Number of Participants With Fibrosis Grades 0 to 4 at Baseline (Part 1)Baseline (Day 1)Liver fibrosis stage was scored using the METAVIR system (Grade 0 to 4). Grade 0 indicates no fibrosis, Grade 1 indicates stellate enlargement of portal tract but without septa formation, Grade 2 indicates enlargement of portal tract with rare septa formation, Grade 3 indicates numerous septa without cirrhosis and grade 4 indicates cirrhosis. The number of participants with fibrosis grades ranging from 0 to 4 at Baseline is presented.
Number of Participants With Adverse Events and Serious Adverse Events (Part 1)Up to Week 96An adverse event (AE) is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. A serious adverse event (SAE) is any untoward medical occurrence that at any dose results in death, are life threatening, requires hospitalization or prolongation of hospitalization or results in disability/incapacity, and congenital anomaly/birth defect.
Percentage of Participants With Relapse Rates in Groups A1 and B1 at the End of Follow-up (Part 2)Up to Week 96Virological relapse rate was defined as percentage of participants with non-detectable HCV RNA (\< 15 IU/ml) at the EoT and detectable HCV RNA (≥ 15 IU/ml) at the end of FU. The end of treatment was defined as Week 48 in Group A1 and Week 72 in Group B1 and the end of follow-up was defined as Week 72 in Group A1 and Week 96 in Group B1.
Percentage of Participants With Virological Response Rate in Groups A, B, C, and D at the End of Treatment Period (Part 1)Up to Week 72End of treatment response (ETR) rate was defined as the percentage of participants in each group with non-detectable HCV RNA at completion of the treatment period (HCV negative at Week 24 of Group D, Week 48 of Group A and at Week 72 of Groups B and C). Participants without a HCV RNA results at this time point were considered as non-responders. End of the treatment period was defined as Week 48 for Group A, Week 72 for Groups B and C, and Week 24 for Group D.
Percentage of Participants Achieving Sustained Virological Response in Groups C and D by Genotype at the End of Follow-up (Part 2)Up to Week 96The SVR was defined as the percentage of participants in each group with non-detectable HCV RNA result at 24 weeks post completion of the treatment period (HCV RNA \< 15 IU/ml at Week 48 of Group D and at Week 96 of Group C). Participants without a HCV RNA results at this time point were considered as non-responders. The end of follow-up was defined as Week 96 for Group C and Week 48 for Group D.

The Sustained Virological Response (SVR) was defined as the percentage of participants in each group with non-detectable HCV RNA result at 24 weeks post completion of the treatment period (HCV RNA \< 15 IU/ml at Week 72 of Groups A1 and E, and at Week 96 of Group B1). Participants without a HCV RNA results at this time point were considered as non-responders. The end of follow-up was defined as Week 72 for Groups A1 and E, and Week 96 for Group B1. The SVR for treatment Groups A1 + B1 and E, stratified for genotype (Genotype I and Genotype IV) is presented.

Time frame: Up to Week 96

Population: The ITT population included all participants randomized and allocated to receive treatments. Here, 'n' = the number of participants analyzed according to genotype.

Mean Fatigue Severity Scale Scores for Groups A1, B1 and C Over Time (Part 2)

The FSS is an instrument consisting of 10 self-administered questions. The FSS items were scored by calculating the average response to all answered items (including the 9 questions and the fatigue symptoms). Each of the 9 questions had answers within a score range of 1-7. A score of 1 for any question indicates less fatigue in everyday life and a score of 7 indicates a higher likelihood of fatigue in everyday life. The mean FSS scores are presented at Baseline (Day 1), Week 24, Week 48 and Week 72 (for Groups A1, B1 and C) and at Week 96 (for Groups B1 and C).

Time frame: Baseline (Day 1), Week 24, Week 48 and Week 72, and Week 96

Mean Short Form-36 Questionnaire Scores for Groups A1, B1, and C Over Time (Part 2)

The SF-36 is a quality of life instrument consisting of a 36-item questionnaire. The SF-36 items were scored and transformed according to the SF-36 Health Survey Manual & Interpretation Guide. Summary scores for SF-36 dimensions (physical functioning, role functioning, bodily pain, general health, vitality, social functioning, mental health, health transition) as well as physical and mental summary measures were compiled after imputation of mean scores for missing items if more than 50% of dimension-related items were available. Scores for health transition ranged from 0 (worst) to 5 (best). Scores for all other dimensions ranged from 0 (worst) to 100 (best). The mean SF-36 scores were presented at Baseline (Day 1), Week 24, Week 48, Week 72 (for Groups A1, B1 and C) and at Week 96 (for Groups B1 and C). Lower score indicate worsening.

Mean Short Form-36 Questionnaire Scores for Groups A and B Over Time (Part 1)

The Short Form-36 (SF-36) is a quality of life instrument consisting of a 36-item questionnaire. The SF-36 items were scored and transformed according to the SF-36 Health Survey Manual and Interpretation Guide. Summary scores for SF-36 dimensions (physical functioning, role functioning, bodily pain, general health, vitality, social functioning, mental health, health transition) as well as physical and mental summary measures were compiled after imputation of mean scores for missing items if more than 50% of dimension-related items were available. Scores for health transition ranged from 0 (worst) to 5 (best). Scores for all other dimensions ranged from 0 (worst) to 100 (best). The mean SF-36 scores are presented at Baseline (Day 1), Week 24, Week 48, Week 72 (for Groups A and B) and at Week 96 (for Group B). Lower score indicate worsening.

Time frame: Baseline (Day 1), Week 24, Week 48, Week 72, and Week 96

Population: The ITT population included all participants randomized and allocated to receive treatments. Here, 'n' = the number of participants analyzed at a given time point.

Number of Participants With Adverse Events and Serious Adverse Events (Part 1)

An adverse event (AE) is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. A serious adverse event (SAE) is any untoward medical occurrence that at any dose results in death, are life threatening, requires hospitalization or prolongation of hospitalization or results in disability/incapacity, and congenital anomaly/birth defect.

Time frame: Up to Week 96

Population: The safety population included all participants who received at least on dose of (either) study drug and had at least one post-baseline safety assessment.
