Abstract
Background Therapeutic approaches to HIV-suppressed immunological non-responders (INRs) remain unsettled. We previously reported efficacy of Chinese herbal Tripterygium wilfordii Hook F in INRs. Its derivative (5R)-5-hydroxytriptolide (LLDT-8) on CD4 T cell recovery was assessed. Methods The phase II, double-blind, randomized, placebo-controlled trial was conducted in adults patients with long-term suppressed HIV infection and suboptimal CD4 recovery, at nine hospitals in China. The patients were 1:1:1 assigned to receive oral LLDT-8 0.5 mg or 1 mg daily, or placebo combined with antiretroviral therapy for 48 weeks. All study staff and participants were masked. The primary endpoints include change of CD4 T cell counts and inflammatory markers at week 48. This study is registered on ClinicalTrials.gov (NCT04084444) and Chinese Clinical Trial Register (CTR20191397). Findings A total of 149 patients were enrolled from Aug 30, 2019 and randomly allocated to receiving LLDT-8 0.5 mg daily (LT8, n = 51), 1 mg daily (HT8, n = 46), or placebo (PL, n = 52). The median baseline CD4 count was 248 cells/mm 3 , comparable among three groups. LLDT-8 was well-tolerated in all participants. At 48 weeks, change of CD4 counts was 49 cells/mm 3 in LT8 group (95% confidence interval [CI]: 30, 68), 63 cells/mm 3 in HT8 group (95% CI: 41, 85), compared to 32 cells/mm 3 in placebo group (95% CI: 13, 51). LLDT-8 1 mg daily significantly increased CD4 count compared to placebo (p = 0.036), especially in participants over 45 years. The mean change of serum interferon-γ-induced protein 10 was −72.1 mg/L (95% CI −97.7, −46.5) in HT8 group at 48 weeks, markedly decreased compared to −22.8 mg/L (95% CI −47.1, 1.5, p = 0.007) in placebo group. Treatment-emergent adverse events (TEAEs) were reported in 41 of 46 (89.1%) participants in HT8 group, 43 of 51 (84.3%) in LT8, and 42 of 52 (80.7%) in PL group. No drug-related SAEs were reported. Interpretation LLDT-8 enhanced CD4 recovery and alleviated inflammation in long-term suppressed INRs, providing them a potential therapeutic option.

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 it
