Brief summary
The Polypill Approach for Multiple Cardiovascular Risk Factors (PACIF) trial is a multicenter randomized controlled trial that will test the effectiveness and safety of a fixed-dose combination strategy for the integrated management of hypertension, dyslipidemia, and type 2 diabetes among adults aged 50 to 75 years without prior cardiovascular disease in China. The trial will evaluate whether a fixed-dose combination strategy improves the 10-year cardiovascular disease risk estimated using the PREVENT equations at Phase 1. Participants will be further followed to determine whether the fixed-dose combination strategy reduces major cardiovascular events and improves cognitive outcomes compared with usual care at Phase 2.
Detailed description
The overall objective of the PACIF Trial is to test a fixed-dose combination strategy for the integrated management of hypertension, dyslipidemia, and diabetes. This multicenter randomized controlled trial will evaluate whether a polypill-based approach, compared with usual care, improves cardiovascular risk factor control and reduces cardiovascular disease events among adults with multiple cardiovascular risk factors but without prior cardiovascular disease. The trial will recruit an estimated 8,252 participants aged 50 to \<75 years who have hypertension, dyslipidemia, and type 2 diabetes. Participants will be randomly assigned to receive either a fixed-dose combination strategy or usual care. In the intervention group, the study medication regimen will consist of eight prespecified fixed-dose formulations combining blood pressure-lowering, lipid-lowering, and glucose-lowering therapies. These formulations include olmesartan medoxomil/amlodipine, rosuvastatin, ezetimibe, and dapagliflozin, with indapamide included in selected formulations. Treatment will be adjusted among the prespecified fixed-dose formulations according to participants' blood pressure levels, treatment targets, tolerability, and safety. Additional open-label medications may be used according to guideline recommendations and clinical judgment if the prespecified treatment targets are not achieved with the fixed-dose combination strategy. Treatment targets are defined as blood pressure \<130/80 mmHg, LDL cholesterol \<1.8 mmol/L, and HbA1c \<7.0%. The primary outcome at Phase 1 is the ACC/AHA 10-year cardiovascular disease risk estimated by the PREVENT equations. In addition, changes in PREVENT-estimated 10-year ASCVD and heart failure risk, the proportions of participants achieving the prespecified blood pressure, lipid, and glycemic targets, and changes in individual cardiovascular risk factors will also be evaluated. The primary outcome at Phase 2 is a composite cardiovascular disease outcome including cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, heart failure requiring hospitalization or treatment, and coronary revascularization. Cognitive outcomes will also be assessed, with incident all-cause dementia prespecified as a major secondary outcome.
Interventions
Participants assigned to the intervention group will receive a fixed-dose combination strategy for the integrated control of blood pressure, lipid, and glucose. Eight prespecified fixed-dose formulations will be used, differing in antihypertensive intensity and rosuvastatin dose. All formulations will include olmesartan medoxomil/amlodipine, rosuvastatin, ezetimibe 10 mg, and dapagliflozin 10 mg, with indapamide 2.5 mg included in selected formulations. The olmesartan medoxomil/amlodipine dose will range from 5/1.25 mg to 20/5 mg, and the rosuvastatin dose will be either 5 mg or 10 mg. Treatment will be selected and adjusted among the prespecified fixed-dose formulations according to participants' blood pressure levels, treatment targets, tolerability, and safety. If the prespecified blood pressure, lipid, or glycemic targets are not achieved despite the highest fixed-dose regimen, additional open-label medications may be prescribed according to guideline recommendations.
