Inclusion Criteria

1. Adult =18 years
2. A recent acute HCV infection or reinfection (see definition below) occurred within 6 months prior screening:
An acute HCV infection is defined by:
a. HCV RNA was detectable within 6 months after a negative HCV RNA or HCV serology test.
OR
b. Detectable HCV RNA and an acute clinical hepatitis occurred within 5 months prior to the screening visit.

Clinical Hepatitis is defined by:
- ALT = 250 IU/L with normal ALT within the preceding 8 months,
or
- ALT = 500 IU/L with either no measured ALT or with abnormal ALT within the preceding 8 months.

HCV reinfection is defined by:
a. Documented de novo infection after prior clearance after treatment or spontaneously,
- After-treatment clearance is defined by one negative HCV RNA = 6 months after end of treatment.
- Spontaneous clearance is defined by two negative HCV RNA a minimum of 6 months apart.
OR
b. Documented infection with a new viral strain, confirmed by phylogenetic or genotypic analysis.

3. Infection with HCV genotype 1 or 4 (confirmed at screening visit or by using a previous biological test performed 1 to 4 weeks before D0)
4. Plasma HCV-RNA = 1000 UI/mL (confirmed at screening visit or by using a previous biological test performed 1 to 4 weeks before D0)
5. Confirmed HIV infection
6. Without HIV treatment or with an acceptable stable HIV treatment for at least two weeks (See section 8.3 of the protocol)
7. Body weight =40 kg and =125 kg
8. Female patients with child-bearing potential and their heterosexual partners must use adequate contraception from the date of screening until 30 days after administration of the last dose of study drug. Male participants must agree to consistently and correctly use a condom, while their female partner must use adequate contraception from the date of screening until 30 days after administration of the last dose of study drug
9. Informed and signed consent
10. Patients with Health insurance (Sécurité Sociale or Couverture Médicale Universelle)

4. Confirmed cirrhosis (before acute HCV diagnosis).
5. Any other causes of acute hepatitis.
6. Pregnant or breast-feeding women.
7. Transplant recipients.
8. Evolutive malignancy.
9. Patients with a history of non-adherence, who will be at risk of being unable to respect the study follow-up timetable.
10. Patients participating in another clinical trial (with an experimental treatment) or within an exclusion period of a previous clinical trial at screening.
11. Patients under legal gardianship or incarcerated.
