Eligibility 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.
