Treatment and study plan

Primary outcomes

  1. Number of Participants with Adverse Drug Reactions (ADRs)

    Time frame: Up to approximately 36 weeks

    Adverse drug reactions are defined as adverse events of which a causal relationship with Maviret could not be ruled out.

  2. Percentage of Participants with Adverse Drug Reactions (ADRs)

    Time frame: Up to approximately 36 weeks

    Adverse drug reactions are defined as adverse events of which a causal relationship with Maviret could not be ruled out.

  3. Number of Participants with Serious Adverse Events (SAEs)

    Time frame: Up to approximately 36 weeks

    A serious adverse event (SAE) is an event that results in death, is life-threatening, requires or prolongs hospitalization, results in a congenital anomaly, persistent or significant disability/incapacity or is an important medical event that, based on medical judgement, may jeopardize the participant and may require medical or surgical intervention to prevent any of the outcomes listed above. Treatment-emergent serious adverse events (TESAEs) are defined as any event that began or worsened in severity after the first dose of study drug.

  4. Percentage of Participants with Serious Adverse Events (SAEs)

    Time frame: Up to approximately 36 weeks

    A serious adverse event (SAE) is an event that results in death, is life-threatening, requires or prolongs hospitalization, results in a congenital anomaly, persistent or significant disability/incapacity or is an important medical event that, based on medical judgement, may jeopardize the participant and may require medical or surgical intervention to prevent any of the outcomes listed above. Treatment-emergent serious adverse events (TESAEs) are defined as any event that began or worsened in severity after the first dose of study drug.

Secondary outcomes

  1. Percentage of participants achieving Sustained Virologic Response 12 (SVR12)

    Time frame: At Week 12

    Defined as HCV Ribonucleic acid (RNA) not detected 12 weeks after the last dose of study drug.

  2. Percentage of participants achieving Sustained Virologic Response (SVR)

    Time frame: At 4, 8, 12 and 24 weeks after last dose of Maviret (up to approximately 36 weeks)

    SVR defined as HCV Ribonucleic acid (RNA) < Lower limit of quantification (LLOQ).

  3. Percentage of Participants with On-Treatment Virologic Failure (Breakthrough)

    Time frame: Up to approximately 36 weeks

    On-treatment virologic failure (breakthrough) defined as at least 1 documented HCV RNA < 50 IU/mL followed by HCV RNA ≥ 50 IU/mL during treatment or failure to suppress (each measured on-treatment HCV RNA value ≥ 50 IU/mL).

  4. Percentage of Participants with After-Treatment Virologic Failure (Relapse)

    Time frame: Up to approximately 36 weeks

    After-treatment virologic failure (relapse) is defined as confirmed HCV RNA ≥ LLOQ between the end of treatment and 24 weeks after the last dose of study drug among participants who completed treatment with HCV RNA levels < LLOQ at the end of treatment.
