WRITE study aim at identifying the effectiveness of an innovative individualized schedule of treatment as compared to standard regimen in patients with chronic HCV genotype 2 and 3.
The investigators are going to compare weight-based dosages of ribavirin, in combination with Peginterferon alpha-2a, with standard fixed dosages of 800 mg. Patients will be evaluated at week 4 with an assay of sensitivity of 15 IU/ml. Patients with week 4 response will discontinue treatment at week 12 in both arms. Patients with HCV RNA still detectable at week 4 and receiving 1000-1200 mg of ribavirin in arm A will discontinue treatment at week 24, whereas patients with HCV RNA still detectable at week 4 and receiving 800 mg of ribavirin in arm B will be treated till week 48.
A standard treatment arm (C) including patients treated for 24 weeks with Peginterferon alpha-2a and fixed 800 mg ribavirin dosage will be used as control arm.
83 studies on the registry are indexed under Hepatitis, Chronic; 10 are open to participants now.
This study's enrollment of 1,150 is above the median of 84 across 59 interventional studies indexed under Hepatitis, Chronic.

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
A score of how well the liver works in people with liver disease such as cirrhosis: class A is mild, B moderate and C severe.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

Patients will be randomly assigned in 3:3:1 ratio to three treatment arms. In the standard treatment group (Arm C), patients will be treated for 24 weeks independently of the HCV RNA status at week 4 with Peginterferon alpha-2a at a dose of 180 mcg weekly in combination with oral ribavirin administered at a dosage of 800 mg/day. Patients enrolled in Arm C will be treated for standard 24 weeks duration of treatment.
Patients enrolled in Arm A will receive Peginterferon alpha-2a at a dosage of 180 mcg weekly in combination with oral ribavirin administered at a dosage of 1000 mg/day for patients with a body weight \< 75 kg or 1200 mg/day for those with a body weight \> 75 kg. Patients with week 4 viral clearance (labelled as rapid virological responders, RVR) will be allocated to 12 week treatment duration (Arm A), whereas those without RVR will be treated for 24 weeks (Arm A)
Drug: Peginterferon alpha-2a + Ribavirin
Patients enrolled in Arm B will receive Peginterferon alpha-2a at a dosage of 180 mcg weekly in combination with oral ribavirin administered at a dosage of 800 mg/day. Patients with week 4 viral clearance (labelled as rapid virological responders, RVR) will be allocated to 12 week treatment duration (Arm B), whereas those without RVR will be treated for 48 weeks (Arm B)
Drug: Peginterferon alpha-2a + Ribavirin
Administration of ribavirin at a dosage of 1000 or 1200 mg per day based on body weight \< or \> 75 kg for 24 weeks (Arm A). Treatment duration of 48 weeks with standard fixed dose of ribavirin (800 mg/day) (Arm B). These schedules will be compared with diagram of standard therapy with 800 mg daily of ribavirin for 24 weeks (Arm C)
Also known as: Peginterferon alpha-2a (40 kD) PEGASYS, Copegus or Rebetol, Ribavirin Teva
Sustained virological Response (SVR)
The primary measure of efficacy will be HCV RNA not detectable in serum samples 24 weeks after the end of therapy (SVR).
Time frame: 6 months after the end of treatment
Rapid virological response (RVR)
proportion of patients with undetectable HCV RNA 4 weeks after the start of treatment
Time frame: On treatment week 4
Ran from Dec 2018 to primary completion in Nov 2019, 11 months.
