Sofosbuvir-Containing Regimens Without Interferon For Treatment of Acute Hepatitis C Virus (HCV) Infection
People who are recently infected with HCV have a great chance of being cured of the infection when they are treated with a combination of two drugs within the first 6 months of being infected. This study is being done to see if a new drug can replace one of the old drugs to provide a safer, more effective, and better tolerated treatment for new HCV infection. The name of this new drug is sofosbuvir (SOF), and it will replace pegylated-interferon alfa (PEG-IFN, a drug given as a weekly injection under the skin). SOF will be given in combination with ribavirin (RBV), a drug approved by the Food and Drug Administration (FDA). All participants in this study will be monitored while on treatment at weeks 1, 2, 4, 8, and 12. All participants will be evaluated for a sustained virologic response (SVR) (undetectable HCV RNA levels) 1, 2, 4, and 8 (for the 8-week regimen) or 12 (for the 12-week regimen) weeks after starting study treatment. After completing treatment, all participants will be evaluated for a SVR 2, 4, 8, 12, and 24 weeks after the end of treatment.

AIDS Clinical Trials Group -- ACTG A5327
AIDS Clinical Trials Group
- HIV-1 infection
- A documented confirmation of acute HCV infection within 6 months prior to A5327 entry or HCV reinfection as described in section 4.1.2 of the protocol.
- 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 is defined as date of first elevated liver enzymes or date of first serologic evidence of HCV seroconversion and/or viremia (whichever occurs first).
- HIV-1 ARV therapy should fall into one of the following criteria: 1. ARV untreated, for example due to (1) lack of indication per provider (CD4 T-cell count >500 cells/mm3) or (2) decision by provider and subject to defer ARV therapy during the study drug dosing period (8 or 12 weeks), or (3) elite controller (CD4+ >200 cells/mm3). OR 2. On a stable, protocol-approved (ddI, d4T, ZDV excluded), ARV regimen for >8 weeks prior to screening with a CD4 T-cell count >200 cells/mm3 and a documented plasma HIV-1 RNA level <50 copies/mL by any laboratory that has a Clinical Laboratory Improvement Amendments (CLIA) certification or its equivalent ? 8 weeks preceding the A5327 screening visit. HIV-1 RNA levels should be within 1 year of the screening visit. Screening HIV-1 RNA must be < 50 copies/mL as measured by any local laboratory using an FDA-approved assay.
- Candidates must have the following laboratory parameters within 10-42 days prior to study entry: 1. Hemoglobin ? 12 g/dL for male, ?11 g/dL for female subjects 2. International normalized ratio (INR) ?1.5 x ULN unless subject has known hemophilia or is stable on an anticoagulant regimen affecting INR 3. Albumin ? 3 g/dL 4. Creatinine clearance (CrCl) ? 60 mL/min, as calculated by the Cockcroft-Gault equation (refer to section 6.3.5 for calculator utility link)
- Screening electrocardiogram (ECG) without clinically significant abnormalities as determined by the investigator.
- Female subjects of reproductive potential (defined as women who have not been post-menopausal for at least 24 consecutive months, ie, who have had menses within the preceding 24 months, or women who have not undergone surgical sterilization, specifically hysterectomy and/or bilateral oophorectomy or bilateral salpingectomy) must have a negative serum pregnancy test with a sensitivity of at least 25 mIU/mL performed during screening, within 48 hours prior to study entry.
- All subjects must agree 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 are pregnant or breastfeeding are not eligible. A male candidate who has a pregnant female partner is not eligible for the study.
- When participating in sexual activity that could lead to pregnancy, all subjects 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 include:
- 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)
- Subjects who are not of reproductive potential (women who have been post-menopausal for at least 24 consecutive months or have undergone hysterectomy and/or bilateral oophorectomy or salpingectomy or men who have documented azoospermia or undergone vasectomy) are eligible without requiring the use of contraceptives. Acceptable documentation of sterilization and menopause is specified as 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 is required to document successful vasectomy)
- Discharge summary
- Follicle stimulating hormone-release factor (FSH) measurement elevated into the menopausal range as established by the reporting laboratory.
- Intention to comply with the dosing instructions for study drug administration and able to complete the study schedule of assessments.
- Received investigational drug or device within 60 days prior to study entry.
- Prior exposure to a direct-acting antiviral (DAA) targeting the HCV NS5B polymerase. NOTE: DAAs include but are not limited to: mericitabine, ABT-333, ABT-072, BI-207127, BMS-791325, VX-222, tegobuvir, IDX719, setrobuvir, GS-9669, VX-135.
- Chronic liver disease of a non-HCV etiology (eg, hemochromatosis, Wilson's disease, ?1 antitrypsin deficiency, primary sclerosing, cholangitis).
- Presence of active or acute AIDS-defining opportunistic infections within 30 days prior to study entry. NOTE: A list of AIDS-defining opportunistic infections as defined by the CDC, can be found in Appendix B of the following document: http://www.cdc.gov/mmwr/preview/mmwrhtml/00018871.htm
- Active, serious infection (other than HIV-1 or HCV) requiring parenteral antibiotics, antivirals, or antifungals within 30 days prior to study entry.
- Infection with hepatitis B virus (HBV) defined as HBsAg positive.
- Evidence of acute hepatitis A infection defined as HAV IGM positive.
- History of clinically significant hemoglobinopathy (eg, sickle cell disease, thalassemia).
- Chronic use of systemically administered immunosuppressive agents (eg, prednisone equivalent > 10 mg/day).
- History of solid organ transplantation.
- Current or prior history of clinical hepatic decompensation (eg, ascites, encephalopathy or variceal hemorrhage).
- History of a gastrointestinal disorder (or post operative condition) that could interfere with the absorption of the study drug.
