Ethyl-EPA in Huntington disease
Bibliographic record
Abstract
BACKGROUND: Preliminary evidence suggests beneficial effects of pure ethyl-eicosapentaenoate (ethyl-EPA) in Huntington disease (HD). METHODS: A total of 135 patients with HD were randomized to enter a multicenter, double-blind, placebo-controlled trial on the efficacy of 2 g/d ethyl-EPA vs placebo. The Unified Huntington's Disease Rating Scale (UHDRS) was used for assessment. The primary end point was outcome at 12 months on the Total Motor Score 4 subscale (TMS-4). Analysis of covariance (ANCOVA) and a chi2 test on response, defined as absence of increase in the TMS-4, were performed. RESULTS: A total of 121 patients completed 12 months, and 83 did so without protocol violations (PP cohort). Intent-to-treat (ITT) analysis revealed no significant difference between ethyl-EPA and placebo for TMS-4. In the PP cohort, ethyl-EPA proved better than placebo on the chi2 test on TMS-4 (p < 0.05), but missed significance on ANCOVA (p = 0.06). Secondary end points (ITT cohort) showed no benefit of ethyl-EPA but a significantly worse outcome in the behavioral severity and frequency compared with placebo. Exploring moderators of the efficacy of ethyl-EPA on TMS-4 showed a significant interaction between treatment and a factor defining patients with high vs low CAG repeats. Reported adverse events were distributed equally between treatment arms. CONCLUSIONS: Ethyl-eicosapentaenoate (ethyl-EPA) (purity > 95%) had no benefit in the intent-to-treat cohort of patients with Huntington disease, but exploratory analysis revealed that a significantly higher number of patients in the per protocol cohort, treated with ethyl-EPA, showed stable or improved motor function. Further studies of the potential efficacy of ethyl-EPA are warranted.

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.
