Entecavir and Peginterferon Alfa‐2a in Adults With Hepatitis B e Antigen–Positive Immune‐Tolerant Chronic Hepatitis B Virus Infection
Bibliographic record
Abstract
Monotherapy with interferon or nucleoside analog is generally not recommended during the immune‐tolerant (IT) phase of chronic hepatitis B virus (HBV) infection. Recognition that high HBV DNA levels are associated with hepatocellular carcinoma has increased interest in treating HBV in the IT phase. Small pediatric studies reported efficacy with combination nucleoside analog and interferon therapy. The aim of this study was to evaluate the safety and efficacy of the combination of entecavir and peginterferon in adults in the IT phase of chronic HBV infection. Hepatitis B e antigen (HBeAg)–positive adults with HBV DNA > 10 7 IU/mL and alanine aminotransferase (ALT) ≤ 1.5 times the upper limit of normal (ULN) (male: ≤ 45, female: ≤ 30 U/L) received entecavir 0.5 mg daily for 8 weeks followed by the addition of peginterferon alfa‐2a 180 µg/week to entecavir for an additional 40 weeks. The primary endpoint was HBeAg loss and HBV DNA ≤ 1,000 IU/mL 48 weeks after end of treatment (EOT). Among 28 participants from 11 sites, the median age was 37.2 (range: 22‐61) years, 54% were male, and 96% were Asian. Nearly all were infected with genotype C (64%) or B (32%). Median baseline HBV DNA was 8.2 log 10 IU/mL, and ALT was 0.9 times the ULN. Although one (4%) participant cleared HBeAg, none met the primary endpoint of both HBeAg loss AND HBV DNA ≤ 1,000 IU/mL 48 weeks post‐EOT. ALT elevations > 5 times the ULN occurred in eight (29%) participants, and none were associated with icterus. Forty‐eight weeks posttreatment, HBV DNA rebounded to baseline levels in all participants, including the participant who lost HBeAg, and ALT values returned to near baseline levels in all but four participants. Conclusion : A lead‐in strategy of 8 weeks of entecavir followed by combination peginterferon and entecavir therapy for 40 weeks had limited efficacy in adults in the IT phase of chronic HBV infection and cannot be recommended.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
