· Tolerability of peginterferon alfa-2a and high-dose ribavirin (percentage of patients completing treatment on full or >80% of total intended dose and reasons for dose adjustments)

E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
ancillary I: Monitoring immune responses in chronic hepatitis C virus infected patients during combined treatment with high-dose or standard-dose weight-based ribavirin and peginterferon alfa-2a. Date: September 20th, 2007, version 1. Objective: The aim of this ancillary study is to evaluate intrahepatic immune responses in chronic HCV patients treated with peg-interferon alfa-2a, and standard or high dose ribavirin. The intrahepatic immune response will be correlated to peripheral immune activity (in blood).
ancillary II: Monitoring the effects of erythropoietin treatment in chronic hepatitis C virus infected patients during combined treatment with high-dose or standard-dose weight-based ribavirin and peginterferon alfa-2a. Date: September 20th, 2007, version 1. Objective: A common side effect of ribavirin treatment is anemia, which will -if required- be treated with erythropoietin and possible blood transfusions. The aim of this ancillary study is to examine the effects of erythropoietin treatment on the immune system by assessing immune parameters in blood before and after erythropoietin treatment (epoietin beta, NeoRecormon).
Ancillary III: Influence of standard-dose or high-dose weight-based ribavirin and interferon on semen quality.
Objective: Primary aim:
To assess changes in sperm chromatin structure integrity and in seminal parameters according to the WHO criteria for semen analysis.
Secondary aims:
To assess if the changes in sperm due to treatment with ribavirin and peginterferon alpha are reversible.
To investigate if possible teratogenic and embyolethal effects of ribavirin are dose-dependent.
Ancillary IV: Monitoring ribavirin plasma concentrations and the effect on HCV viral load and mutation rate in NS5B domain in hepatitis C patients during combined treatment with peginterferon alfa-2a and high or standard dose weight-based ribavirin.
Objective: The aim of this ancillary study is to assess the ribavirin plasma concentration and the effect on HCV load and to determine whether high dose ribavirin leads to a higher number of mutations in the HCV NS5B region during combination treatment with peginterferon and standard or high dose ribavirin. |

E.3 | Principal inclusion criteria |
• Hepatitis C genotype 1 or 4
• High viral load (>400,000 IU/ml)
• Indication for antiviral treatment or patient’s desire for antiviral treatment
• Hepatitis C treatment naïve
• Liver biopsy within 3 years of the date of the screening visit or when liver
biopsy is contraindicated e.g. in patients with clotting diseases e.g hemophilia and von Willebrand disease or when a patient refuses to undergo a new liver biopsy in case the liver biopsy is older than 3 years, substitution by fibroscan is allowed.
• Age 18-70 years
|
|
E.4 | Principal exclusion criteria |
• Signs of progressive liver disease, beyond generally accepted criteria for HCV antiviral therapy:
serum bilirubin >35 μmol/l, or albumin <36 g/l or prothrombin time >4 sec prolonged or platelets <90x109/l (if normal values are different at the local laboratory, upper and lower limits of the local laboratory should be used)
decompensated cirrhosis (Child-Pugh Grade B or C)
• Hepatic imaging (ultrasound, CT or MRI) with the evidence of hepatocellular carcinoma (hepatic imaging should be performed within 3 months prior to screening for cirrhotic patients and within 6 months prior to screening for non-cirrhotic patients)
• Thrombocytosis, defined as platelet count > 500.000/mm³
• History or evidence of risk of thrombosis
• Poorly controlled hypertension
• Other acquired or inherited causes of liver disease that could explain liver disease activity (if an indicator is present at screening, additional examinations should be done to confirm or rule out the diagnoses):
Alcoholic liver disease (indicator: MCV>100)
Obesity induced liver disease (indicators: steatosis proven by biopsy or ultrasound in association with a body mass index >30)
Drug related liver disease (indicator: positive history of hepatic toxic drug intake with a causal relation)
Auto-immune hepatitis (indicators: IgG >30g/l, anti smooth-muscle or antinuclear antibodies titer 1:40)
Hemochromatosis (indicator: ferritin >1000 μg/l)
Wilson’s disease (indicator: ceruloplasmin (<0.2 g/l)
Alpha-1 antitrypsin deficiency (indicator alpha-1 antitrypsin <0.8 g/L)
• Co-infection with hepatitis B virus or human immunodeficiency virus (HIV)
• Any cardiovascular dysfunction (e.g. decompensatio cordis, myocard infarction, present or history of arrythmia)
• Other significant medical illness that might interfere with this study: significant pulmonary or renal dysfunction, malignancy other than skin basocellular carcinoma in previous 5 years, immunodeficiency syndromes (e.g.: steroid therapy, organ transplants other than cornea and hair transplant)
• Contra-indications for peginterferon and/or ribavirin:
Severe psychiatric disorder, such as major psychoses, suicidal ideation, suicidal attempt and/or manifest depression. Severe depression would include the following: (a) subjects who have been hospitalized for depression, (b) subjects who have received electroconvulsive therapy for depression, or (c) subjects whose depression has resulted in a prolonged absence of work and/or significant disruption of daily functions. Subjects with a history of mild depression may be considered for entry into the protocol provided that a pretreatment assessment of the subject’s mental status supports that the subject is clinically stable and that there is ongoing evaluation of the patient’s mental status during the study
Visual symptoms related to retinal abnormalities
Pregnancy, breast-feeding or inadequate contraception
Thalassemia, spherocytosis
• Females who are pregnant or intending to become pregnant or male partners of females who are pregnant or intending to become pregnant
• Absolute neutrophil count (ANC) <1.40x109/l
• Hemoglobin (Hb) <7.5 mmol/l (female) or <8.1 mmol/l (male)
• Creatinine clearance below 50 ml/min (Cockroft/Gault) at screening
• Substance abuse, such as I.V. drugs or alcohol (indicator: >28 drinks/week). If the subject has a history of substance abuse, to be considered for inclusion into the protocol, the subject must have abstained from using the abused substance for at least 1 year
• Treatment with investigational antiviral drugs e.g. protease/polymerase inhibitors within 6 months before start of therapy
• Any other condition which in the opinion of the investigator would make the patient unsuitable for enrollment, or could interfere with the patient participating in and completing the study
