Dendritic Cell Immunotherapy for HIV-1 Infection Using Autologous HIV-1 RNA
Bibliographic record
Abstract
BACKGROUND: The genomic heterogeneity of HIV-1 impedes the ability of consensus sequences in vaccines to elicit effective antiviral immune responses. AGS-004 amplifies translation-competent RNA molecules encoding for Gag, Rev, Vpr, and Nef from the patient's autologous virus and loads them into dendritic cells. METHODS: This phase IIB, multicenter, 2:1 randomized, double-blind, placebo-controlled study enrolled 54 HIV-1-infected patients on antiretroviral therapy with viral loads (VLs) <50 copies per milliliter, current CD4 T-cell counts >450 cells per cubic millimeter, and nadir counts >200 cells per cubic millimeter, to receive intradermal injections of study product into the axillary lymph node region every 4 weeks. At week 16, a 12-week analytical treatment interruption (ATI) was undertaken. RESULTS: There was no difference in the end-of-ATI VL (average of values from weeks 11 and 12) between the 2 arms of the study [4.39 (4.17, 4.69) vs. 4.47 (3.76, 4.64) log10 HIV-1 RNA; P = 0.73]. Between arms, no change between pre-antiretroviral therapy VL and the end-of-ATI VL [-0.06 (0.24, -0.32) vs. -0.17 (0.17, -0.32) log10 HIV-1 RNA; P = 0.43] was observed. When interferon-γ, interleukin-2, tumor necrosis factor α, CD107a, and granzyme b expressions were measured by multicolor flow cytometry, a greater percentage of AGS-004 than of placebo recipients had multifunctional cytotoxic T-lymphocyte responses induced in the CD28+/CD45RA-CD8 effector/memory T-cell population to dendritic cells electroporated with autologous antigens. Adverse events consisted of transient, mild (grade 1) local injection site reactions. CONCLUSIONS: Despite the induction of HIV-specific effector/memory CD8 T-cell responses, no antiviral effect was seen after the administration of AGS-004 when compared with placebo.

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.
