Brief Summary:

Early identification of acute HCV infection is essential to prevent chronic infections and the long-term liver disease complications that may occur. Early identification and treatment of HCV during the acute phase can result in significantly higher response rates with shorter durations of therapy.

Pegylated-interferon alfa (PEG-IFN) was the typical treatment for HCV infection. Participants subcutaneously inject PEG-IFN where the average duration of treatment was approximately 20 weeks. With the advancement of direct-acting antivirals (DAAs), it was possible to see if a new DAA might be non-inferior compared to (PEG-IFN).

The study was designed to see if a fixed-dose combination tablet can replace the old HCV treatments by being more effective, safer and better tolerated in HIV-infected participants with new HCV infection. The study was a Phase I, open-label, two cohort clinical trial, in which 44 acutely HCV-infected HIV-1 positive participants were enrolled. Participants in each cohort were evaluated in two steps: on treatment (Step 1) and follow-up after discontinuing study treatment (Step 2). The cohorts were enrolled sequentially. Participants in Cohort 1 were enrolled and administered oral Sofosbuvir (SOF) in combination with weight-based ribavirin (RBV). Participants in Cohort 2 were enrolled and administered an oral fixed dose combination of Ledipasvir/Sofosbuvir (LDV/SOF).


Condition or disease Intervention/treatment Phase
HIV-1 Infection Hepatitis Drug: Sofosbuvir Drug: Ribavirin Drug: Ledipasvir/Sofosbuvir Phase 1

Detailed Description:

The first cohort opened with SOF/RBV treatment for 12 weeks and accrued 17 participants. All participants under Cohort 1 were to visit the clinical site at weeks 0, 1, 2, 4, 8, and 12 when on treatment (Step 1), then visit the clinical site again at 2, 4, 8, 12 and 24 weeks during follow-up after discontinuing study treatment (Step 2).

The second cohort opened for an 8-week treatment of LDV/SOF and included at least 27 subjects. All participants under Cohort 2 were to visit the clinical site at weeks 0, 1, 2, 4, and 8 when on treatment (Step 1), then visit the clinical site again at 2, 4, 8, 12 and 24 weeks during follow-up after discontinuing study treatment (Step 2).

Both cohorts were monitored for safety and HCV viral load response while the participants were on treatment.

The primary objective did not compare the cohorts together; instead, each study cohort was formally assessed for efficacy with sustained virologic response 12 weeks after treatment based on non-inferiority criteria compared to a historical SVR rate of 60% separately.

Primary Outcome Measures :
  1. Percentage of Participants With Sustained Virologic Response 12 (SVR12) [ Time Frame: At 12 weeks after date of last dose of study treatment. The duration of study treatment for Cohort 1 and Cohort 2 were 12 and 8 weeks, respectively. ]

    SVR12 was defined as HCV RNA undetectable less than the lower limit of quantification, Target Not Detected (<LLOQ TND) of the assay at 12 weeks after date of last dose of study treatment.

    For both Cohort 1 and Cohort 2, the 12 week measurement used for determining SVR12 was the measurement obtained closest to 84 days (i.e. 12*7 days), within the window 79 to 112 days inclusive. If a participant did not have an HCV RNA measurement within this window, then the participant was considered as having detectable HCV RNA at 12 weeks unless the preceding and subsequent HCV RNA measurements were both undetectable (<LLOQ TND).

    A two-sided 90% confidence interval was calculated for this percentage using the Blyth-Still-Casella method.


  2. Percentage of Participants With an Occurrence of a Grade ≥ 2 Adverse Event, Serious AE According to ICH Criteria, or Treatment-limiting AE. [ Time Frame: From initiation of study treatment to 28 days after last dose of study treatment. The duration for study treatment for Cohort 1 and Cohort 2 were 12 and 8 weeks, respectively. ]

    Any adverse event occurring after initiation of study treatment through to 28 days after the date of last dose of study treatment was included (except that an event that was ongoing at the same grade from before start of study treatment was excluded). Adverse events consisted of Grade ≥ 2 primary diagnosis, primary sign/symptoms, and primary laboratory abnormality. It also included any serious adverse event according to ICH criteria and any treatment-limiting AE (ie, an AE reported as the reason for permanent discontinuation of study treatment).

    A two-sided 90% confidence interval was calculated for the percentage using the Blyth-Still-Casella method.



Secondary Outcome Measures :
  1. Percentage of Participants With HCV RNA Undetectable During Study Treatment [ Time Frame: 1, 2, 4, 8 and, for the 12-week regimen, 12 weeks after starting study treatment. ]

    HCV RNA undetectable was defined as an HCV RNA measurement <LLOQ, TND. If there was no measurement at a scheduled time, then the participant was considered as having detectable HCV RNA at that time, unless both the preceding and succeeding measurements were undetectable.

    A two-sided 90% confidence interval was calculated for each proportion using the Blyth-Still-Casella method.


  2. Percentage of Participants With HCV RNA Undetectable After End of Study Treatment [ Time Frame: 2, 4, 8 and 24 weeks after last dose of study treatment. The duration of study treatment for Cohort 1 and Cohort 2 were 12 and 8 weeks, respectively. ]

    HCV RNA undetectable is defined as an HCV RNA measurement <LLOQ, TND. If there was no measurement at a scheduled time, then the participant was considered as having detectable HCV RNA at that time, unless both the preceding and succeeding measurements were undetectable. This outcome measure was referred to as SVR2, SVR4, SVR8 and SVR24 where SVR means sustained virologic response.

    A two-sided 90% confidence interval was calculated for the percentage using the Blyth-Still-Casella method.


  3. Number of Participants Who Had HCV Virologic Relapse [ Time Frame: From end of study treatment through to 24 weeks after end of study treatment. The duration of study treatment for Cohort 1 and Cohort 2 were 12 and 8 weeks, respectively. ]
    HCV virologic relapse was defined as HCV RNA undetectable at end-of-treatment but HCV RNA quantifiable during follow-up with subsequent confirmation as quantifiable.

  4. Percentage of HCV Virologic Failure Participants That Developed SOF- or LDV-Associated Resistance Mutations [ Time Frame: At time of HCV virologic failure; any time from start of study treatment to 24 weeks after end of study treatment. Duration of study treatment for Cohort 1 and 2 were 12 and 8 weeks, respectively. ]
    Percentage of participants who developed SOF- or LDV-associated resistance mutation found within HCV Virologic Failure participants. HCV virologic failure was defined as HCV RNA undetectable at end-of-treatment but HCV RNA quantifiable during follow-up with subsequent confirmation as quantifiable.

  5. Count and Percentage of Participants With an Adverse Event by Type. [ Time Frame: Any time from start of treatment to 28 days after date of last dose of study treatment. The duration of study treatment for Cohort 1 and Cohort 2 were 12 and 8 weeks, respectively. ]
    The adverse events considered were Grade 2 or higher adverse events (primary diagnosis, primary sign and symptom, or a primary lab), SAE according to ICH criteria, or treatment-limiting adverse events. Participants may experience more than one type of adverse event.

  6. Count of Participants With HIV-1 RNA <50 Copies/mL [ Time Frame: 4 and 12 weeks after start of study treatment for Cohort 1. 4 and 8 weeks after start of study treatment for the 8-week regimen used in Cohort 2) ]
    Because all except one participant had HIV-1 RNA < 50 copies/mL, participants were categorized according to whether or not their HIV-1 RNA was <5 copies/mL at each follow-up evaluation.

  7. Change in CD4+ Cell Count [ Time Frame: Baseline to 12 weeks after end of study treatment. Duration of study treatment for Cohort 1 and Cohort 2 were 12 and 8 weeks, respectively. ]

Criteria

A5327 Eligibility Criteria (Cohort 1 and Cohort 2)

Step 1 inclusion criteria for both cohorts (Cohort 1 and Cohort 2)

  • HIV-1 infection, documented by any licensed rapid HIV test or HIV enzyme or chemiluminescence immunoassay (E/CIA) test kit at any time prior to study entry and confirmed by a licensed Western blot or a second antibody test by a method other than the initial rapid HIV and/or E/CIA, or by HIV-1 p24 antigen, or plasma HIV-1 RNA viral load. [NOTE: The term "licensed" refers to a FDA-approved kit, which is required for all IND studies.] WHO (World Health Organization) and CDC (Centers for Disease Control and Prevention) guidelines mandate that confirmation of the initial test result must use a test that is different from the one used for the initial assessment. A reactive initial rapid test should be confirmed by either another type of rapid assay or an E/CIA that is based on a different antigen preparation and/or different test principle (e.g., indirect versus competitive), or a Western blot or a plasma HIV-1 RNA viral load.
  • A documented confirmation of acute HCV infection within 6 months prior to A5327 entry or HCV reinfection as described below:

    1. Acute HCV infection was defined as meeting one of the following criteria and exclusion of other causes of acute hepatitis:

      • New (<24 weeks prior to initial A5327 entry) ALT elevation to ≥5X upper limit of normal (ULN) OR >250 U/L in patients with documented normal ALT in the preceding 12 months or ≥10X ULN OR >500 U/L in patients with abnormal or no measured ALT baseline in the preceding 12 months with detectable HCV RNA excluding those with any prior positive anti-HCV. OR
      • Detectable HCV RNA with prior negative anti-HCV Ab or undetectable HCV RNA within the preceding 6 months.
    2. Acute HCV reinfection was defined by documentation of clearance of prior infection (as evidenced by positive anti-HCV Ab) either spontaneously or after treatment with two negative HCV RNA a minimum of 6 months apart AND meeting one of the following criteria in addition to exclusion of other causes of acute hepatitis:

      • New (<24 weeks prior to initial A5327 entry) ALT elevation to ≥5X ULN OR >250 U/L in patients with documented normal ALT in the preceding 12 months or ≥10X ULN OR >500 U/L in patients with abnormal or no measured ALT baseline in the preceding 12 months with detectable HCV RNA. OR
      • Positive HCV RNA with prior negative HCV RNA within the preceding 6 months.
  • HCV RNA confirmed to be detectable >12 weeks after first laboratory evidence of acute HCV and still within the <24 week from first laboratory evidence of acute HCV infection window. First laboratory evidence of infection was defined as date of first elevated liver enzymes or date of first serologic evidence of HCV seroconversion and/or viremia (whichever occurs first). [NOTE: If the screening visit occurred less than 12 weeks from the first laboratory evidence of infection, then the participant was required a pre-entry study visit to confirm detectable HCV RNA at least 12 weeks from the first laboratory evidence of infection had passed. It was optimal for this pre-entry visit to occur as close as possible to 12 weeks from first laboratory evidence to ensure timely treatment. Potential participants who entered screening but who had an undetectable HCV RNA (<LLOQ TND) at the pre-entry visit (when required) exhibited evidence of possible spontaneous clearance and will not meet the entry criteria.]
  • Body mass index (BMI) ≥ 18 kg/m^2
  • Screening electrocardiogram (ECG) without clinically significant abnormalities as determined by the investigator.
  • Willing and able to provide written informed consent.
  • Men and women age ≥ 18 years.
  • All participants agreed not to participate in a conception process (eg, active attempt to become pregnant or to impregnate, sperm donation, in vitro fertilization). [NOTE: Female candidates who were pregnant or breastfeeding were not eligible. A male candidate who had a pregnant female partner was not eligible for the study.]
  • When participating in sexual activity that could lead to pregnancy, all participants must agree to use at least two reliable forms of contraceptive simultaneously while receiving protocol-specified medications, and for 6 months after stopping the medications. Such methods included:

    • Condoms (male or female) with or without a spermicidal agent
    • Diaphragm or cervical cap with spermicide
    • Intrauterine device (IUD)
    • Tubal ligation
    • Hormone-based contraceptive (except those containing drospirenone)

[NOTE: Providers and participants were advised that not all contraceptive choices listed above can prevent HIV transmission and that some may actually increase the risk of HIV acquisition. Study participants who were sexually active with HIV-1 negative or unknown HIV-1 serostatus partners were advised that they needed to consider effective strategies for reducing the risk of HIV transmission, as well as meeting the requirement for effective contraception during their participation in the study. Study participants discussed contraceptive choices and HIV risk reduction methods with their health care provider.]

  • Participants who were not of reproductive potential (women who had been post-menopausal for at least 24 consecutive months or had undergone hysterectomy and/or bilateral oophorectomy or salpingectomy or men who had documented azoospermia or undergone vasectomy) were eligible without requiring the use of contraceptives. Acceptable documentation of sterilization and menopause was specified below.

    • Written or oral documentation communicated by clinician or clinician's staff of one of the following:
    • Physician report/letter
    • Operative report or other source documentation in the patient record (a laboratory report of azoospermia was required to document successful vasectomy)
