P5364Safety profile of bempedoic acid: pooled analysis of 4 phase 3 clinical trials
Bibliographic record
Abstract
Abstract Background/Introduction Bempedoic acid (BA), an oral, first-in-class, ATP-citrate lyase inhibitor, lowers low-density lipoprotein cholesterol (LDL-C) in patients who do not achieve sufficient lipid lowering with guideline-recommended first-line therapies. Purpose We evaluated the safety profile of BA in phase 3 trials. Methods Data were pooled from 4 randomised, double-blind, placebo-controlled studies that enrolled patients with hyperlipidaemia who were receiving stable lipid-lowering therapy (LLT; maximally tolerated statins +/− nonstatin therapies) and required additional LDL-C lowering. Patients were randomised (2:1) to BA 180 mg or placebo daily for 12 to 52 weeks. Results Median exposure for 3621 patients (2424 BA, 1197 placebo) was 363 days. Background LLT included a statin +/− other LLT (83.8%), nonstatin LLT alone (9.4%), or none (6.8%). Adverse event (AE) and serious AE rates were similar between groups (Table). The most common AEs in the BA and placebo groups were nasopharyngitis (7.4% vs 8.9%), myalgia (4.9% vs 5.3%), and urinary tract infection (4.5% vs 5.5%). Rates of new-onset/worsening diabetes were 4.0% for BA and 5.6% for placebo. No AEs leading to discontinuation differed by ≥0.5% between treatments. All fatal AEs were judged by the investigator as unrelated to treatment. A trend was observed for a lower 3-component major adverse cardiac event rate with BA vs placebo (hazard ratio, 0.85; 95% confidence interval: 0.53 to 1.37). Changes in uric acid, creatinine, and haemoglobin were apparent at week 4, stable over time, and reversible after stopping BA. Gout occurred in 1.4% and 0.4% of patients in the BA and placebo groups, respectively. The safety profile of BA was consistent across background therapies, demographics, and disease characteristics.

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.
