Efficacy and Safety of Single-Pill Combination of Rosuvastatin and Ezetimibe in Chinese Patients with Primary Hypercholesterolemia Inadequately Controlled by Statin Treatment (ROZEL): A Randomized, Double-Blind, Double Dummy, Active-Controlled Phase 3 Clinical Trial
Bibliographic record
Abstract
INTRODUCTION: Many patients with primary hypercholesterolemia do not achieve their plasma low-density lipoprotein cholesterol (LDL-C) goals with statin alone under a recommended dose of statin (e.g., 10 mg rosuvastatin) in China. The objective of this phase III study was to evaluate the efficacy and safety of a new single-pill combination (SPC) of rosuvastatin 10 mg/ezetimibe 10 mg (R10/E10) in this population. METHODS: This was a randomized, double-blind, double-dummy, active-controlled study in patients with primary hypercholesterolemia inadequately controlled with statin alone. The participants were randomized 1:1 to receive SPC R10/E10 or R10. The primary objective was to demonstrate the superiority of SPC R10/E10 vs. R10 in reducing the LDL-C levels after 8 weeks. RESULTS: This trial randomized 305 participants to SPC R10/E10 (n = 153) and R10 (n = 152). The superiority of SPC R10/E10 over R10 was demonstrated with the least square (LS) mean difference of percent change in LDL-C from baseline to week 8: - 13.85% (95% confidence interval [CI] - 20.15% to - 7.56%, P < 0.0001). The proportion of participants who achieved the LDL-C target (< 2.6 mmol/l) at week 8 was larger with SPC R10/E10 (n = 80, 54.1%) than with R10 (n = 42, 29.2%) (Odds ratio = 2.80, 95% CI 1.70 to 4.61, P < 0.0001). No unexpected safety findings were reported. CONCLUSION: The results suggest that SPC R10/E10 improve LDL-C reduction and goal achievement in Chinese patients with primary hypercholesterolemia not adequately controlled on statin therapy, without new safety findings.

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.
