HBeAg Seroconversion.
These exacerbations occurred in the absence of HBeAg seroconversion and presented as serum ALT elevations and increases in serum HBV DNA.
HBeAg Seroconversion*p value vs lamivudine< 0.05 a.
Baseline ALT levels> 2x ULN and baseline HBV DNA< 9 log10 copies/ml were associated with higher rates of HBeAg seroconversion in HBeAg-positive patients.
HBeAg Seroconversion*p value vs lamivudine< 0.05 a.
Twenty-five percent(14 of 56) of patients in the tenofovir disoproxil group and 24%(7 of 29)of patients in the placebo group achieved HBeAg seroconversion at Week 48.
HBeAg seroconversion was increased in patients with elevated ALT levels;
The Kaplan-Meier estimates of the proportion of patients who maintained HBeAg seroconversion for at least 52 weeks following treatment discontinuation were 86.2% for telbivudine and 92.8% for lamivudine.
HBeAg seroconversion and loss assessed only in patients with detectable HBeAg at baseline.
Treatment with entecavir for up to 96 weeks(n= 141) resulted in cumulative response rates of 30% for HBV DNA< 300 copies/ml by PCR,85% for ALT normalisation and 17% for HBeAg seroconversion.
Patients with sustained HBeAg seroconversion had a mean HBV DNA of 3.3 log10 copies/ml; and 73.7% had HBV DNA< 4 log10 copies/ml.
In the subgroup of patients with baseline ALT levels≥ 2x ULN(320), a significantly higher proportion of telbivudine patients than lamivudine patients achieved HBeAg seroconversions at week 104(36% vs 28%, respectively).
Therefore, following HBeAg seroconversion, patients should be periodically monitored to determine that serologic and clinical responses are being maintained.
Of those HBeAg positive subjects, 95% achieved non-detectable HBV DNA,39% achieved HBeAg seroconversion, 90% achieved ALT normalisation at week 52 and 0.5% exhibited resistance at week 48.
The response rate of HBeAg seroconversion was lower in patients with HBV genotype D, also in patients with no to minimal increase in ALT level at baseline(see Table 23).
After a median off-treatment follow-up period of 120 weeks, the majority of HBeAg-positive telbivudine treated-patients showed sustained HBeAg loss(83.3%; 25/30),and sustained HBeAg seroconversion(79.2%; 19/24).
However, the proportions of subjects who achieved HBeAg seroconversion at week 48 were similar(11%) between the placebo arm and the adefovir dipivoxil 10 mg arm in adolescent patients.
Among patients from study WV16240, who received Pegasys monotherapy and entered the long-term follow-up study,the rate of sustained HBeAg seroconversion 12 months after the end of therapy was 48%(73/ 153).
HBeAg seroconversion was increased in patients with elevated ALT levels; 77%(20/26) of patients with pre-treatment ALT> 2 x ULN seroconverted.
Continued lamivudine treatment for an additional 2 years in patients who had failed to achieve HBeAg seroconversion in the initial 1 year controlled studies resulted in further improvement in bridging fibrosis.
Confirmed HBeAg seroconversion occurred in 47%(118/252) of subjects treated with lamivudine and 93%(320/345) of subjects receiving lamivudine became HBV DNA negative(VERSANT[version 1], bDNA assay, LLOD< 0.7 MEq/ml) during the study.
For lamivudine(n= 355), cumulative response rates were39% for HBV DNA< 300 copies/ ml by PCR, 79% for ALT normalisation, 26% for HBeAg seroconversion, and 2% for HBsAg seroconversion(3% for HBsAg loss).
In HBeAg positive patients, treatment should be administered at least until HBeAg seroconversion(HBeAg and HBV DNA loss with HBeAb detection on 2 consecutive serum samples at least 3 months apart) or until HBsAg seroconversion or in case of evidence of loss of efficacy(see section 4.4).
Moreover, in the subgroup of patients with baseline ALT levels≥ 2x ULN(320),a significantly higher proportion of telbivudine patients than lamivudine patients achieved HBeAg seroconversions at week 104(36% vs 28%, respectively).
In HBeAg-positive patients without cirrhosis, treatment should be administered for at least 6-12 months after HBeAg seroconversion(HBeAg loss and HBV DNA loss with anti-HBe detection) is confirmed or until HBsAg seroconversion or there is evidence of loss of efficacy.
For patients originally assigned to entecavir treatment, the reduction in HBV DNA at 48 weeks was -4.20 log10 copies/ml,ALT normalisation had occurred in 37% of patients with abnormal baseline ALT and none achieved HBeAg seroconversion.
Telbivudine-treated patients who achieved PCR negativity by week 24 had the highest rates of PCR negativity and HBeAg seroconversion(in HBeAg-positive patients), and the lowest overall rates of virological breakthrough at week 104.
Exploratory analyses based on limited data show paediatric patients with greater decline in HBV-DNA at week 12 of therapy were more likely to achieve HBeAg seroconversion at 24 weeks of follow-up(Table 24).
Treatment response for HBeAg-positive patients was defined as HBeAg seroconversion(defined as loss of HBeAg and presence of anti-HBe)+ HBV DNA< 2,000 IU/mL at 6 months post-treatment and treatment response for HBeAg-negative patients was defined as HBV DNA< 2,000 IU/mL+ ALT normalization at 6 months posttreatment.
Telbivudine-treated patients who achieved undetectable HBV DNA by PCR by week 24 had the highest rates of HBV DNA undetectability and HBeAg seroconversion(in HBeAg-positive patients), and the lowest overall rates of virological breakthrough at week 104.
