Outcome Measures

1. Primary Outcome

Title	Percentage of Participants Achieving Sustained Virologic Response 12 Weeks After the End of All Study Therapy (SVR12)
Description	Blood was drawn from each participant to assess Hepatitis C Virus ribonucleic acid (HCV RNA) plasma levels using the Roche COBAS™ Taqman™ HCV Test, v2.0 (High Pure System). The Roche COBAS Taqman HCV Test, v2.0 assay (High Pure System) had a lower limit of quantification of 15 IU/mL and a limit of detection of 9.3 IU/mL (in plasma). SVR12 was defined as undetectable (<9.3 IU/mL) HCV RNA at 12 weeks after the end of all study therapy.
Time Frame	12 weeks after end of all therapy (Study Week 24)

Outcome Measure Data

Analysis Population Description

Full Analysis Set (FAS); all allocated participants who received at least 1 dose of study treatment.

Arm/Group Title	Grazoprevir+Elbasvir
Arm/Group Description:	Participants received a FDC of grazoprevir 100 mg plus elbasvir 50 mg once daily for 12 weeks and were followed-up for 24 weeks.
Overall Number of Participants Analyzed	218
Measure Type: Number; Unit of Measure: percentage of participants
	96.3

2. Primary Outcome

Title	Percentage of Participants Experiencing Adverse Events (AEs) During the Treatment Period and First 14 Follow-up Days
Description	An AE is defined as 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 unfavourable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol -specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an AE.
Time Frame	Treatment Period plus first 14 follow-up days (up to 14 weeks)

Outcome Measure Data

Analysis Population Description

All Participants as Treated (APaT) Population; all participants who received at least one dose of study treatment.

Arm/Group Title	Grazoprevir+Elbasvir
Arm/Group Description:	Participants received a FDC of grazoprevir 100 mg plus elbasvir 50 mg once daily for 12 weeks and were followed-up for 24 weeks.
Overall Number of Participants Analyzed	218
Measure Type: Number; Unit of Measure: percentage of participants
	73.9

3. Primary Outcome

Title	Percentage of Participants Discontinuing Study Therapy Due to AEs During the Treatment Period
Description	An AE is defined as 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 unfavourable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol -specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an AE.
Time Frame	Treatment Period (up to 12 weeks)

Outcome Measure Data

Overall Number of Participants Analyzed	218
Measure Type: Number; Unit of Measure: percentage of participants
	0.0

4. Secondary Outcome

Title	Percentage of Participants Achieving Sustained Virologic Response 24 Weeks After the End of All Study Therapy (SVR24)
Description	Blood was drawn from each participant to assess HCV RNA plasma levels using the Roche COBAS™ Taqman™ HCV Test, v2.0 (High Pure System). The Roche COBAS Taqman HCV Test, v2.0 assay (High Pure System) had a lower limit of quantification of 15 IU/mL and a limit of detection of 9.3 IU/mL (in plasma). SVR24 was defined as undetectable (<9.3 IU/mL) HCV RNA at 24 weeks after the end of all study therapy.
