Bitherapy and monotherapy Summary of the safety profile The most common treatment-related adverse reactions reported during clinical trials with ViraferonPeg in combination with ribavirin in adults, seen in more than half of the study subjects, were fatigue, headache, and injection site reaction.
Additional adverse reactions reported in more thanMedicinal product no longer authorised 18 25 % of subjects included nausea, chills, insomnia, anaemia, pyrexia, myalgia, asthenia, pain, alopecia, anorexia, weight decreased, depression, rash and irritability.
The most frequently reported adverse reactions were mostly mild to moderate in severity and were manageable without the need for modification of doses or discontinuation of therapy. Fatigue, alopecia, pruritus, nausea, anorexia, weight decreased, irritability and insomnia occur at a notably lower rate in patients treated with ViraferonPeg monotherapy compared to those treated with combination therapy (see Table 6).

Psychiatric and Central Nervous System (CNS) Severe CNS effects, particularly depression, suicidal ideation and attempted suicide have been observed in some patients during ViraferonPeg therapy, and even after treatment discontinuation mainly during the 6-month follow-up period.
Other CNS effects including aggressive behaviour (sometimes directed against others such as homicidal ideation), bipolar disorders, mania, confusion and alterations of mental status have been observed with alpha interferons. Patients should be closely monitored for any signs or symptoms of psychiatric disorders.
If such symptoms appear, the potential seriousness of these undesirable effects must be borne in mind by the prescribing physician and the need for adequate therapeutic management should be considered. If psychiatric symptoms persist or worsen, or suicidal or homicidal ideation is identified, it is recommended that treatment with ViraferonPeg be discontinued, and the patient followed, with psychiatric intervention as appropriate.
Patients with existence of, or history of severe psychiatric conditions If treatment with peginterferon alfa-2b is judged necessary in adult patients with existence or history of severe psychiatric conditions, this should only be initiated after having ensured appropriate individualised diagnostic and therapeutic management of the psychiatric condition.
3). 4 % vs 1 %) during treatment and during the 6-month follow-up after treatment. g. depression, emotional lability, and somnolence). Patients with substance use/abuse HCV infected patients having a co-occurring substance use disorder (alcohol, cannabis, etc) are at an increased risk of developing psychiatric disorders or exacerbation of already existing psychiatric disorders when treated with alpha interferon.
If treatment with alpha interferon is judged necessary in these patients, the presence of psychiatric co-morbidities and the potential for other substance use should be carefully assessed and adequately managed before initiating therapy.

Bitherapy:
Predictability of sustained virological response - All patients, irrespective of genotype, who have demonstrated serum HCV-RNA below the limits of detection at week 12 should receive 48 weeks of bitherapy. e. 1). Retreatment duration greater than 48 weeks in non-responder patients with genotype 1 has not been studied with pegylated interferon alfa-2b and ribavirin combination therapy.
Paediatric population (bitherapy only) – Dose to be administered Dosing for children 3 years of age and older and adolescent patients is determined by body surface area for ViraferonPeg and by body weight for ribavirin. The recommended dose of ViraferonPeg is 60 g/m2/week subcutaneously in combination with ribavirin 15 mg/kg/day orally in two divided doses with food (morning and evening).
Paediatric population (bitherapy only) - Duration of treatment Genotype 1:
The recommended duration of treatment with bitherapy is 1 year. By extrapolation from clinical data on combination therapy with standard interferon in paediatric patients (negative predictive value 96 % for interferon alfa–2b/ribavirin), patients who fail to achieve virological response at 12 weeks are highly unlikely to become sustained virological responders.
Therefore, it is recommended that children and adolescent patients receiving ViraferonPeg/ribavirin combination be discontinued from therapy if their week 12 HCV-RNA dropped < 2 log10 compared to […]
If necessary, an inter-disciplinary approach including a mental health care provider or addiction specialist should be considered to evaluate, treat and follow the patient. Patients should be closely monitored during therapy and even after treatment discontinuation.
Early intervention for re-emergence or development of psychiatric disorders and substance use is recommended. Growth and development (children and adolescents) During the course of therapy lasting up to 48 weeks in patients ages 3 through 17 years, weight loss and growth inhibition were common.
Long-term data available in children treated with theMedicinal product no longer authorised 11 combination therapy of pegylated interferon/ribavirin are indicative of substantial growth retardation. 1). 1). - It is important to consider that the combination therapy induced a growth inhibition, that resulted in reduced height in some patients.
- This risk should be weighed against the disease characteristics of the child, such as evidence of disease progression (notably fibrosis), co-morbidities that may negatively influence the disease progression (such as HIV co-infection), as well as prognostic factors of response (HCV genotype and viral load).
Whenever possible the child should be treated after the pubertal growth spurt, in order to reduce the risk of growth inhibition. Although data are limited, no evidence of long-term effects on sexual maturation was noted in the 5-year observational follow-up study.
More significant obtundation and coma, including cases of encephalopathy, have been observed in some patients, usually elderly, treated at higher doses for oncology indications. While these effects are generally reversible, in a few patients full resolution took up to three weeks.
Very rarely, seizures have occurred with high doses of interferon alpha. e. patients with genotype 2 and 3), treatment may be possible without histological confirmation. Current treatment guidelines should be consulted as to whether a liver biopsy is needed prior to commencing treatment.
, urticaria, angioedema, bronchoconstriction, anaphylaxis) have been observed rarely during interferon alfa-2b therapy. If such a reaction develops during treatment with ViraferonPeg, discontinue treatment and institute appropriate medical therapy immediately.
Transient rashes do not necessitate interruption of treatment. Cardiovascular system As with interferon alfa-2b, adult patients with a history of congestive heart failure, myocardial infarction and/or previous or current arrhythmic disorders, receiving ViraferonPeg therapy require close monitoring.
It is recommended that patients who have pre-existing cardiac abnormalities have electrocardiograms taken prior to and during the course of treatment. Cardiac arrhythmias (primarily supraventricular) usually respond to conventional therapy but may require discontinuation of ViraferonPeg therapy.
There are no data in children or adolescents with a […]
