The 3-hydroxy-3-methylglutaryl-coenzyme A reductase inhibitors ("statins") and the cholesterol-lowering medication ezetimibe are widely used in the treatment of patients with high- and very high-risk atherosclerotic cardiovascular disease. This study compared the efficacy and tolerability of a fixed-dose combination (FDC) of ezetimibe/atorvastatin (EZ/AS) with those of escalating doses of atorvastatin monotherapy in Chinese patients with hypercholesterolemia uncontrolled with statin monotherapy.This Phase III, 12-week, randomized, double-blind study included patients aged 18 to 80 years with hypercholesterolemia uncontrolled on atorvastatin 10 or 20 mg/d monotherapy. After a 5-week run-in period of treatment with atorvastatin 10 or 20 mg/d (cohorts A and B, respectively), or a bioequivalent dosage of another statin, patients were randomized in a 1:1 ratio within each cohort to receive EZ/AS 10/10 mg FDC (EZ10/AS10) or atorvastatin 20 mg (AS20), once daily (cohort A); or EZ/AS 10/20 mg FDC (EZ10/AS20) or atorvastatin 40 mg (AS40), once daily (cohort B). The primary end point was the percentage change from baseline in low-density lipoprotein cholesterol (LDL-C). Tolerability was also evaluated.Of the 454 patients enrolled, 412 (90.7%) completed the study. The percentage change from baseline in LDL-C was statistically greater with EZ10/AS10 treatment (n = 88) compared with AS20 monotherapy (n = 89) (treatment difference, -19.5%; 95% CI, -26.7% to -12.3%; P0.001). The percentage change from baseline in LDL-C was statistically greater with EZ10/AS20 treatment (n = 137) compared with AS40 monotherapy (n = 140) (treatment difference, -15.9%; 95% CI, -21.0% to -10.7%; P0.001). The safety profile was comparable between the EZ/AS and atorvastatin groups in the two cohorts.The LDL-C level at week 12 was significantly improved with both FDCs compared with escalated doses of atorvastatin (20 or 40 mg/d) in these Chinese patients with hypercholesterolemia uncontrolled on atorvastatin 10 or 20 mg/d. Both FDCs were well tolerated, with no new tolerability-related findings. Chinadrugtrials.org.cn identifier: CTR20190172; ClinicalTrials.gov identifier: NCT03768427. |
