Thank God that it still survives at CHB.
Experience in CHB patients with advanced fibrosis or cirrhosis.
Experience in patients with HBeAg negative CHB.

Who is Roche competing with in the CHB market?
Performance of individual biomarkers at Week 12 of therapy in CHB HBeAg-positive and HBeAg-negative patients according to genotype.
As with other interferons,a higher incidence of neutralising antibodies was seen in CHB.
These adverse reactions were common(≥ 1/ 100 to<1/ 10) in CHB patients treated with Pegasys monotherapy.
For CHB patients, transient flares of ALT levels sometimes exceeding 10x ULN are not uncommon, and may reflect immune clearance.
The recommended duration of therapy is 48 weeks in patients with CHB. Before initiating therapy for CHB, persistently elevated serum ALT levels should have been documented.
In clinical trials of 48 weeks treatment and24 weeks follow-up, the safety profile for Pegasys in CHB was similar to that seen in CHC.
Nigel Key, MB, ChB, FRCP, is an adult hematologist specializing in non-malignant hematologic disorders, particularly those affecting blood coagulation.
Lamivudine has been administered to children and adolescents with compensated CHB in a placebo controlled study of 286 patients aged 2 to 17 years.
In CHB, unlike CHC, disease exacerbations during therapy are not uncommon and are characterised by transient and potentially significant increases in serum ALT.
From the YV25718 study, 31 paediatric patients 3 to 17 years of age with CHB participated in the PK sub-study and received Pegasys according to a BSA category dosing regimen.
In CHB or CHC patients, peginterferon alfa-2a serum concentrations accumulate 2 to 3 fold after 6 to 8 weeks of once weekly dosing compared to single dose values.
The recommended dosage andduration of Pegasys for both HBeAg-positive and HBeAg-negative CHB is 180 micrograms once weekly for 48 weeks.
All clinical trials recruited patients with CHB who had active viral replication measured by HBV DNA, elevated levels of ALT and a liver biopsy consistent with chronic hepatitis.
Experience in children and adolescents: lamivudine has been administered to children and adolescents with compensated CHB in a placebo controlled study of 286 patients aged 2 to 17 years.
Pegasys is indicated for the treatment of HBeAg-positive CHB in non-cirrhotic children and adolescents 3 years of age and older with evidence of viral replication and persistently elevated serum ALT levels.
This recommendation is based on limited data(see section 5.1).• In patients with HBeAg negative CHB(pre-core mutant), the optimal duration of treatment is unknown.
For children and adolescents aged 3 to 17 years with CHB and having a BSA greater than 0.54 m2 and for children and adolescents aged 5 to 17 years with CHC and having a BSA greater than 0.71 m2, the recommended doses for Pegasys are provided in Table 4.
In a clinical trial(YV25718) with 111 paediatric patients(3 to 17 years of age) treated with Pegasys for 48 weeks,the safety profile was consistent with that seen in adults with CHB and in paediatric patients with CHC.
Pegasys pharmacokinetics have been characterized in paediatric patients with CHB(YV25718), as well as in paediatric patients with CHC(NR16141), using population pharmacokinetics.
Experience in patients with HBeAg negative CHB: initial data indicate the efficacy of lamivudine in patients with HBeAg negative CHB is similar to patients with HBeAg positive CHB, with 71% of patients having HBV DNA suppressed below the detection limit of the assay, 67% ALT normalisation and 38% with improvement in HAI after one year of treatment.
Table 4 summarises the undesirable effects reported with Pegasys monotherapy in CHB or CHC patients and with Pegasys in combination with ribavirin in CHC patients.
Pegasys is indicated for the treatment of HBeAg-positive CHB in non-cirrhotic children and adolescents 3 years of age and older with evidence of viral replication and persistently elevated serum.
Study YV25718 was conducted in previously untreated paediatric patients aged 3 to 17 years(51%< 12 years old)with HBeAg positive CHB and ALT> ULN but< 10 x ULN in two blood samples taken≥ 14 days apart during the 6 months before the first dose of study drug.
A patient-level meta-analysis of 9 Pegasys clinical studies(n=1,423) in CHB HBeAg positive and HBeAg-negative patients demonstrated that HBsAg and HBV DNA levels at Week 12 of treatment, are predictive of final treatment outcome at Week 24 post-treatment in certain genotypes.
