Virologic and immunologic activity of PegIntron in HIV disease
Bibliographic record
Abstract
OBJECTIVE: The primary objectives of this study were to evaluate the safety, tolerability, and antiviral activity of pegylated interferon-alpha (PegIntron) in HIV-1 treatment-experienced patients failing their current antiretroviral regimen. DESIGN: This was a phase II, multicenter, randomized, double-blind, placebo-controlled study. METHODS: Patients were randomized to receive either weekly subcutaneous PegIntron 0.5, 1.0, 1.5, or 3 microg/kg or placebo added to their failing antiretroviral regimen for the first 4 weeks of study. Individuals who achieved more than 0.5 log10 reduction in HIV RNA at week 4 were allowed to continue study medication with optimization of their antiretroviral therapy for an additional 24 weeks. RESULTS: In the 259 patients included in the intent-to-treat analysis, changes in plasma HIV RNA from baseline to week 4 were -0.25 (P > 0.5), -0.46 (P = 0.024), -0.39 (P = 0.008), -0.53 (P < 0.001), and -0.17 (P > 0.5) log10 copies/ml in the 0.5, 1.0, 1.5, and 3.0 microg/kg and placebo arms, respectively. No significant changes were seen in CD4 T-cell parameters in any of the treatment or control arms. Adverse events (most commonly fever, flu-like symptoms, other constitutional symptoms, and psychiatric symptoms) resulted in discontinuation of study medication in 13, 17, 16, 28, and 2% of patients in the 0.5, 1.0, 1.5, 3.0 microg/kg, and placebo group, respectively. CONCLUSION: The demonstration of significant antiviral activity in a heavily pretreated patient population with acceptable toxicity and only weekly dosing makes PegIntron a potentially valuable therapy for patients with HIV infection that warrants further investigation in a broader population of 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.
