Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Male or female, at least 18 years of age at time of screening.
  • Screening laboratory result indicating hepatitis C virus (HCV) genotype 1 (GT1) infection.
  • Chronic HCV infection.
  • Subject must be HCV treatment-naïve (i.e., patient has never received a single dose of any approved or investigational regimen) or treatment-experienced (has failed prior interferon [IFN] or pegylated IFN (pegIFN) with or without ribivarin (RBV), or sofosbuvir (SOF) plus RBV with or without pegIFN therapy).
  • Subjects must be non-cirrhotic.

Additional Inclusion Criteria for HCV GT1/human immununovirus type 1 (HIV-1) co-infected patients:

  • HIV-1 antiretroviral treatment (ART) naïve with CD4 ≥ 500 cells/mm3 (or CD4+ % ≥ 29%) at Screening and plasma HIV-1 RNA <1,000 copies/mL at Screening and at least once during the 12 months prior to Screening.

OR

  • On a stable, qualifying HIV-1 ART regimen for at least 8 weeks prior to screening, with CD4 ≥ 200 cells/mm3 (or CD4+ % ≥14%) at Screening and plasma HIV-1 RNA < LLOQ at Screening and at least once during the 12 months prior to Screening.

Exclusion criteria

  • History of severe, life-threatening or other significant sensitivity to any excipients of the study drugs.
  • Female who is pregnant, planning to become pregnant during the study or breastfeeding; or male whose partner is pregnant or planning to become pregnant during the study.
  • Recent (within 6 months prior to study drug administration) history of drug or alcohol abuse that could preclude adherence to the protocol in the opinion of the investigator.
  • Positive test result at Screening for hepatitis B surface antigen (HBsAg).
  • HCV genotype performed during screening indicating co-infection with more than one HCV genotype.
  • Chronic HIV type 2 (HIV-2) infection.

Treatment and study plan

ABT-493/ABT-530

Drug

Tablet; ABT-493 coformulated with ABT-530

Other names: ABT-493 also known as glecaprevir, ABT-530 also known as pibrentasvir, MAVYRET

Primary outcomes

  1. Percentage of Participants With Sustained Virologic Response 12 Weeks Post-treatment (SVR12) in Mono-infected Hepatitis C Virus Genotype 1 (HCV GT1), Direct-acting Antiviral Agent (DAA) Naïve Participants in the 12-Week Treatment Arm

    Time frame: 12 weeks after the last actual dose of study drug

    SVR12 was defined as plasma hepatitis C virus ribonucleic acid (HCV RNA) level less than the lower limit of quantification [<LLOQ]) 12 weeks after the last dose of study drug. The primary efficacy endpoint was noninferiority of the percentage of participants who achieved SVR12 in the 12-week treatment group compared with the historical control rate for HCV GT1 subjects who are treatment-naïve or treated with pegylated-interferon alfa-2a or alfa-2b and ribavirin (pegIFN/RBV).

  2. Percentage of Participants With SVR12: Noninferiority of 8-Week Arm to 12-Week Arm in Mono-infected HCV GT1, DAA-Naïve Participants, Excluding Those Who Discontinued/Experienced Virologic Failure by Week 8 or Had No HCV RNA Value at Week 12 or Later

    Time frame: 12 weeks after last actual dose of study drug

    SVR12 was defined as plasma HCV RNA level <LLOQ 12 weeks after the last dose of study drug. The primary efficacy endpoint was noninferiority of the percentage of mono-infected HCV GT1, DAA-naïve participants (excluding those who discontinued/experienced virologic failure by Week 8 or had no HCV RNA value at Week 12 or later) who achieved SVR12 in the 8-week treatment arm compared with the 12-week treatment arm.

  3. Percentage of Participants With SVR12: Noninferiority of 8-Week Treatment Arm to 12-Week Treatment Arm in Mono-infected HCV GT1, DAA-Naïve Participants

    Time frame: 12 weeks after the last actual dose of study drug

    SVR12 was defined as plasma HCV RNA level <LLOQ 12 weeks after the last dose of study drug. The primary efficacy endpoint was noninferiority of the percentage of mono-infected HCV GT1, DAA-naïve participants who achieved SVR12 in the 8-week treatment arm compared with the 12-week treatment arm.

Secondary outcomes

  1. Percentage of Participants With SVR12 in Mono-infected HCV GT1 Participants

    Time frame: 12 weeks after last actual dose of study drug

    SVR12 was defined as plasma HCV RNA level <LLOQ 12 weeks after the last dose of study drug.

  2. Percentage of Participants With SVR12

    Time frame: 12 weeks after last actual dose of study drug

    SVR12 was defined as plasma HCV RNA level <LLOQ 12 weeks after the last dose of study drug.

  3. Percentage of Participants With SVR12 in Co-infected HCV GT1/Human Immunodeficiency Virus Type 1 (HIV-1) Participants

    Time frame: 12 weeks after last actual dose of study drug

    SVR12 was defined as plasma HCV RNA level <LLOQ 12 weeks after the last dose of study drug.

  4. Percentage of Participants With SVR12 in HCV GT1-infected, Prior Sofosbuvir (SOF) Treatment-Experienced Participants

    Time frame: 12 weeks after last actual dose of study drug

    SVR12 was defined as plasma HCV RNA level <LLOQ 12 weeks after the last dose of study drug.

  5. Percentage of Participants With On-treatment Virologic Failure

    Time frame: Treatment Weeks 1, 2, 4, 8 (end of treatment for 8-week treatment arm), and 12 (end of treatment for 12-week treatment arm) or premature discontinuation from treatment

    On-treatment virologic failure was defined as confirmed increase of >1 log(subscript)10(subscript) IU/mL above the lowest value post-baseline HCV RNA during treatment; confirmed HCV RNA ≥100 IU/mL after HCV RNA <LLOQ during treatment, or HCV RNA ≥LLOQ at end of treatment with at least 6 weeks of treatment.

  6. Percentage of Participants With On-treatment Virologic Failure in Mono-infected HCV GT1, DAA-Naïve Participants

    Time frame: Treatment Weeks 1, 2, 4, 8 (end of treatment for 8-week treatment arm), and 12 (end of treatment for 12-week treatment arm) or premature discontinuation from treatment

    On-treatment virologic failure was defined as confirmed increase of >1 log(subscript)10(subscript) IU/mL above the lowest value post-baseline HCV RNA during treatment; confirmed HCV RNA ≥100 IU/mL after HCV RNA <LLOQ during treatment, or HCV RNA ≥LLOQ at end of treatment with at least 6 weeks of treatment.

  7. Percentage of Participants With Post-treatment Relapse

    Time frame: From the end of treatment through 12 weeks after the last dose of study drug

    Post-treatment relapse was defined as confirmed HCV RNA ≥LLOQ between the end of treatment and 12 weeks after the last dose of study drug among participants who completed treatment with HCV RNA levels <LLOQ at the end of treatment, excluding reinfection.

  8. Percentage of Participants With Post-treatment Relapse in Mono-infected HCV GT1, DAA-Naïve Participants

    Time frame: From the end of treatment through 12 weeks after the last dose of study drug

    Post-treatment relapse was defined as confirmed HCV RNA ≥LLOQ between the end of treatment and 12 weeks after the last dose of study drug among participants who completed treatment with HCV RNA levels <LLOQ at the end of treatment, excluding reinfection.
