Safety, pharmacokinetics and pharmacodynamics of four-hour intravenous infusions of eritoran in healthy Japanese and Caucasian men
Bibliographic record
Abstract
Eritoran, a synthetic analogue of lipid A, has been shown to bind to TLR4/MD-2 complex and thereby block the interaction of endotoxins with TLR4. We report here the results of a study conducted to assess the single-dose safety and tolerability, as well as the pharmacokinetics and pharmacodynamics, of eritoran infusion in Japanese and Caucasian healthy adult men. Sixty-four men (aged 20-45 years; body mass index 18-30 kg/m(2)) were randomized into four groups: 4-mg total dose (six Japanese and six Caucasian men); 12-mg total dose (12 Japanese and 12 Caucasian men); 28-mg total dose (six Japanese and six Caucasian men); and placebo (eight Japanese and eight Caucasian men). Eritoran in single doses up to 28 mg over 4 h was well tolerated, with no apparent ethnic differences noted. Plasma concentrations were slightly higher in Japanese versus Caucasian men; these differences were not significant after adjustment for differences in body mass (clearance: approximately 1.2 ml/h/kg; volume of distribution at steady state: approximately 0.07 l/kg). The ex vivo endotoxin inhibitory activity of eritoran was similar in Japanese and Caucasian men. The data do not indicate any need for clinical dose adjustment for possible ethnic-based differences in drug distribution or metabolism.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
