Safety and efficacy of oral entecavir given for 28 days in patients with chronic hepatitis B virus infection
Bibliographic record
Abstract
Entecavir is an oral antiviral drug with selective activity against hepatitis B virus (HBV). We conducted a randomized, placebo-controlled, dose-escalating study in patients with chronic hepatitis B infection in which we evaluated the efficacy and safety of entecavir given for 28 days. Follow-up was 24 weeks. All doses of entecavir (0.05 mg, 0.1 mg, 0.5 mg, and 1.0 mg) showed a pronounced suppression of replication of the HBV with a 2.21, 2.29, 2.81, and 2.55 mean log(10) reduction of viral load, respectively. Approximately 25% of patients on entecavir showed a decline of HBV DNA below the limit of detection of the Chiron HBV-DNA assay (<0.7 MEq/mL). In the postdosing follow-up period patients who were treated with 0.5 and 1.0 mg of entecavir showed a considerably slower return in their HBV DNA levels to baseline compared with those patients treated with lower dosages (P <.05). All doses of entecavir were well tolerated with no significant difference between treated patients and those receiving placebo. No significant changes in alanine transaminase (ALT) levels within the dose groups and the placebo group between baseline and the end of treatment were observed. Three patients (9%) (1 each in the 0.05-, 0.1-, and 0.5-mg groups) experienced asymptomatic hepatitis flares 16 weeks (2 patients) and 24 weeks (1 patient) after withdrawal of entecavir. In conclusion, in this 28-day study of entecavir a pronounced decrease of HBV DNA was observed and there were no significant side effects in entecavir patients in comparison with placebo-treated patients.

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.
