Real-world evidence on the strategy of olmesartan-based triple single-pill combination in Korean hypertensive patients: a prospective, multicenter, observational study (RESOLVE-PRO).

ABSTRACT:

Background

In this prospective, multicenter, non-comparative observational study, the effectiveness and safety of the triple single-pill combination (SPC) of olmesartan/amlodipine/hydrochlorothiazide (OM/AML/HCTZ) were evaluated in a real clinical practice setting in Korean patients with essential hypertension.

Methods

A total of 3752 patients were enrolled and followed for 12 months after administration of OM/AML/HCTZ. Primary endpoint was change from baseline to month 6 in the mean systolic blood pressure (SBP). Secondary endpoints included changes from baseline in the mean SBP at month 3, 9, 12 and the mean diastolic blood pressure (DBP) at month 3, 6, 9, 12; changes in the mean SBP/DBP according to age and underlying risk factors; and blood pressure control rate (%) at different time points. Adherence to and satisfaction with OM/AML/HCTZ treatment among patients and physicians were assessed by medication possession ratio (MPR) and numeric rating scale, respectively, as exploratory endpoints. Safety was evaluated by the incidence and severity of adverse events (AEs) as well as the discontinuation rate due to AEs.

Results

OM/AML/HCTZ administration led to significant reductions in the mean SBP/DBP by 11.5/6.6, 12.3/7.0, 12.3/7.2, and 12.8/7.4 mmHg from baseline to month 3, 6, 9 and 12, respectively (P < 0.0001). The BP reductions were maintained throughout the 1-year observation period in all patients with different age groups and risk factors (diabetes mellitus, cardiovascular disease, and renal disease). The BP control rate (%) of < 140/90 mmHg was 65.9, 67.9, 68.9, and 70.6% at month 3, 6, 9, and 12, respectively. The mean MPR during the observation period was 0.96. The safety results were consistent with the previously reported safety profile of OM/AML/HCTZ.

Conclusions

Treatment with the triple SPC of OM/AML/HCTZ demonstrated significant effectiveness in reducing SBP/DBP and achieving target BP control with high adherence over the 1-year observation period in Korean hypertensive patients and was well-tolerated.

Project description:IntroductionPatients with hypertension and additional cardiovascular risk factors pose a challenge by requiring more intensive blood pressure (BP) control. Single-pill combination (SPC) therapy can benefit these patients by improving medication adherence.MethodsThis prospective, multicenter observational study assessed the real-world safety and effectiveness of an SPC containing olmesartan, amlodipine, and hydrochlorothiazide (O/A/H) in South Korean patients with hypertension and cardiovascular risk factors. BP control rates, defined as the percentage of patients achieving systolic BP (SBP) < 130 mmHg and diastolic BP (DBP) < 80 mmHg for intensive BP control, and < 140 mmHg and < 90 mmHg, respectively, for standard BP control, were investigated across various cardiovascular risk groups, along with changes in SBP and DBP from baseline to week 24.ResultsThe most prevalent cardiovascular risk factor was age (≥ 45 years in men, ≥ 55 years in women, 86.1%), followed by cardiovascular diseases (64.4%), dyslipidemia (53.7%), body mass index ≥ 25 kg/m2 (53.5%), and diabetes mellitus (DM) (46.3%). Switching to O/A/H showed significant BP reduction, with a mean change of - 17.8 mmHg/- 9.3 mmHg in SBP/DBP within 4 weeks. The intensive BP control rate was 41.4% (95% confidence interval [CI] 39.5, 43.4), and the standard BP control rate was 73.3% (95% CI 71.5, 75.1), with better control rates in the risk age group (43.1% and 74.1%, respectively) and cardiovascular disease group (42.0% and 73.8%, respectively). The DM group had relatively lower control rates (37.5% for intensive control and 69.4% for standard control). Common adverse drug reactions included dizziness (2.91%), hypotension (1.51%), and headaches (0.70%).ConclusionThe SPC therapy of O/A/H caused a rapid and sustained reduction in SBP/DBP in patients' hypertension and additional cardiovascular risk factors. The therapy was safe and well tolerated.Study registration numberKCT0003401 ( https://cris.nih.go.kr/cris/search/detailSearch.do/20795 ).

Project description:The pill burden of patients with hypertension and dyslipidemia can result in poor medication compliance. This study aimed to evaluate the efficacy and safety of fixed-dose combination (FDC) therapy with olmesartan medoxomil (40 mg) and rosuvastatin (20 mg) in Korean patients with mild to moderate hypertension and dyslipidemia. This multicenter, randomized, double-blind, factorial-design study included patients aged ≥20 years with mild to moderate essential hypertension and dyslipidemia. Patients were randomly assigned to receive FDC therapy (40 mg olmesartan medoxomil, 20 mg rosuvastatin), 40 mg olmesartan medoxomil, 20 mg rosuvastatin, or a placebo. The percentage change from baseline in low-density lipoprotein cholesterol levels was compared between FDC therapy and olmesartan medoxomil, and the change from baseline in diastolic blood pressure was compared between FDC therapy and rosuvastatin 8 weeks after treatment. A total of 162 patients were included. The least square mean percentage change (standard error) from baseline in low-density lipoprotein cholesterol levels 8 weeks after treatment was significantly greater in the FDC than in the olmesartan medoxomil group (-52.3% [2.8%] vs -0.6% [3.5%], P<0.0001), and the difference was -51.7% (4.1%) (95% confidence interval: -59.8% to -43.6%). The least square mean change (standard error) from baseline in diastolic blood pressure 8 weeks after treatment was significantly greater in the FDC group than in the rosuvastatin group (-10.4 [1.2] mmHg vs 0.1 [1.6] mmHg, P<0.0001), and the difference was -10.5 (1.8) mmHg (95% confidence interval: -14.1 to -6.9 mmHg). There were 50 adverse events in 41 patients (22.7%) and eight adverse drug reactions in five patients (2.8%). The study found that FDC therapy with olmesartan medoxomil and rosuvastatin is an effective, safe treatment for patients with hypertension and dyslipidemia. This combination may improve medication compliance in patients with a large pill burden.

Project description:Using a single-pill combination (SPC) for hypertension (HTN) treatment resulted in better adherence and persistence than a free-equivalent combination in previous observational studies. The aim of this study is to confirm superior adherence with a triple-component SPC compared with an equivalent two-pill regimen in a randomized controlled trial (RCT) using a medication event monitoring system (MEMS). This is a multicenter, open-label, RCT. Subjects were persons with HTN whose clinic blood pressure was not adequately controlled (systolic >140 mmHg or diastolic >90 mmHg) with a dual combination. Eligible patients were randomized to either the triple-component SPC (olmesartan/amlodipine/hydrochlorothiazide 20/5/12.5 mg) group or the equivalent two-pill (olmesartan/hydrochlorothiazide 20/12.5 mg + amlodipine 5 mg) group and maintained for 12 weeks. Primary outcomes were the difference in percentage of doses taken (PDT) and percentage of days with the prescribed dose taken correctly (PDTc) between the single- and two-pill therapy groups, calculated from MEMS data. From 8 hospitals, 145 patients with HTN were randomized. The single-pill group had significantly higher PDT and PDTc than the two-pill group: median (25-75 percentile) PDT 95.1 (86.7-100.0) versus 92.1 (73.0-97.3); and PDTc 91.0 (79.4-96.5) versus 88.6 (69.2-96.3%), P = 0.04 for both by the Wilcoxon rank sum test. The single-pill combination of the triple-component antihypertensive regimen showed better adherence than the equivalent two-pill therapy. Reducing pill burden by means of a single-pill combination is an effective strategy for enhancing adherence to multiple-agent antihypertensive therapy. Study Highlights WHAT IS THE CURRENT KNOWLEDGE ON THE TOPIC? Previous studies suggested that the use of a single-pill combination (SPC) in hypertension (HTN) treatment produced better adherence and persistence than a free-equivalent combination. However, supportive data are confined to dual-component SPC and came from observational studies using medication possession ratio as an outcome. WHAT QUESTION DID THIS STUDY ADDRESS? The objective of this study is to investigate whether a triple-component SPC improved medication adherence over an equivalent two-pill combination therapy in a randomized controlled trial using medication event monitoring systems. WHAT DOES THIS STUDY ADD TO OUR KNOWLEDGE? Medication adherence in the SPC group was superior to that of two-pill group, confirming previous findings from observational studies. HOW MIGHT THIS CHANGE CLINICAL PHARMACOLOGY OR TRANSLATIONAL SCIENCE? This finding strongly supports the current HTN treatment guideline to prefer SPC with a higher level of evidence.
