Adding Hydrochlorothiazide to Olmesartan/Amlodipine Increases Efficacy in Patients With Inadequate Blood Pressure Control on Dual-Combination Therapy.

ABSTRACT: This randomized, parallel-group study in patients inadequately controlled on olmesartan medoxomil/amlodipine (OLM/AML) 40/10 mg assessed the effects of adding hydrochlorothiazide (HCTZ) 12.5 mg and 25 mg, using seated blood pressure (SeBP) measurements and ambulatory blood pressure (BP) monitoring. Enrolled patients were screened and tapered off of therapy if required. All patients received OLM/AML 40/10 mg and those with mean seated BP (SeBP) ≥140/90 mm Hg after 8 weeks (n=808) were randomized (1:1:1) to continue with OLM/AML 40/10 mg or receive OLM/AML/HCTZ 40/10/12.5 or 40/10/25 mg for a further 8 weeks. The primary endpoint was the change in seated diastolic BP (SeDBP) from the start to the end of the randomized treatment period. The addition of HCTZ 25 mg significantly reduced SeDBP (-2.8 mm Hg; P<.0001), lowered seated systolic BP (SeSBP) and ambulatory DBP and SBP, and improved BP goal rates. In patients uncontrolled on OLM/AML 40/10 mg, adding HCTZ led to further BP reductions, particularly in ambulatory BP.

Project description:BackgroundThis study was to evaluate the efficacy and safety of triple fixed-dose combination (FDC) therapy with olmesartan medoxomil (OM) 20 mg, amlodipine (AML) 5 mg, and hydrochlorothiazide (HCTZ) 12.5 mg (OM/AML/HCTZ 20/5/12.5) in Korean patients with moderate hypertension not controlled with dual FDC therapy (OM/HCTZ 20/12.5).MethodsIn this multicenter, randomized, double-blind, parallel-group study, Korean patients aged 20 to 75 years with stage 2 hypertension who had a mean seated diastolic blood pressure (msDBP) ≥100 mmHg were enrolled when their BP was uncontrolled [mean seated systolic BP (msSBP)/msDBP >140/90 mmHg or msSBP/msDBP >130/80 mmHg with diabetes or chronic kidney disease] with 4-week dual FDC therapy (OM/HCTZ 20/12.5). The patients were randomized to receive either OM/AML/HCTZ 20/5/12.5 or OM/HCTZ 20/12.5 once daily for 8 weeks. At the end of 8 weeks, patients with uncontrolled BP were assigned to receive either OM/AML/HCTZ 40/5/12.5 or OM/AML/HCTZ 20/5/12.5 in an additional 8-week open-label extension period.ResultsA total of 623 patients received a 4-week run-in treatment with OM/HCTZ, 341 patients were randomized, and finally, 167 patients in the OM/AML/HCTZ group and 171 patients in the OM/HCTZ group were analyzed for the full analysis set. Non-responders after the 8 weeks of double-blind treatment continued the 8-week open-label treatment with OM/AML/HCTZ 40/5/12.5 mg (n = 32) or OM/AML/HCTZ 20/5/12.5 mg (n = 71). After 8 weeks of double-blind treatment, the changes in msDBP were -9.50 (8.46) mmHg in the OM/AML/HCTZ group and -4.23 (7.41) mmHg in the OM/HCTZ group (both p < 0.0001 vs. baseline; p < 0.0001 between groups). The response rates for both msSBP and msDBP at week 8 were 65.27 % in the OM/AML/HCTZ group and 37.43 % in the OM/HCTZ group (p < 0.0001 between groups). The response rates for both msSBP and msDBP at week 16 after open-label treatment were 18.75 % in the OM/AML/HCTZ 40/5/12.5 group and 46.48 % in the OM/AML/HCTZ 20/5/12.5 group (p = 0.0073 between groups). All medications were well tolerated.ConclusionIn Korean patients with moderate hypertension not controlled with dual FDC therapy (OM/HCTZ 20/12.5) as first-line therapy, switching to triple FDC therapy (OM/AML/HCTZ 20/5/12.5) was associated with significant BP reductions and greater achievement of BP goals, and was well tolerated (ClinicalTrials.gov Identifier: NCT01838850).

Project description:ObjectivesThis is a prespecified subgroup analysis in Hispanic and non-Hispanic patients of a study that evaluated blood pressure (BP) control with fixed-dose amlodipine/olmesartan medoxomil (AML/OM)-based therapy in patients whose condition was uncontrolled on prior monotherapy.MethodsIn this prospective, open-label, dose-titration study, patients with uncontrolled BP after at least 1 month of antihypertensive monotherapy were switched to fixed-dose AML/OM 5/20 mg. Patients were uptitrated to AML/OM 5/40 and 10/40 mg, with uptitration to AML/OM + hydrochlorothiazide 10/40 + 12.5 mg and 10/40 + 25 mg to achieve target BP. The primary efficacy endpoint was the cumulative proportion of patients achieving seated cuff systolic BP (SeSBP) less than 140 mmHg (<130 mmHg in patients with diabetes mellitus) at 12 weeks. Secondary endpoints included SeBP goal rates, ambulatory BP (ABP) target rates, and mean change from baseline in seated cuff BP (SeBP) and ABP at weeks 12 and 20.ResultsMean baseline BP was similar in Hispanics (153.6/92.8 mmHg; n = 105) and non-Hispanics (153.7/91.8 mmHg; n = 894). At 12 weeks, 72.0% of Hispanics and 76.3% of non-Hispanics achieved the primary endpoint. At week 12, goal rates for cumulative SeBP (<140/90 mmHg or <130/80 mmHg in patients with diabetes) were 69.0% and 71.5% in Hispanic and non-Hispanic patients, respectively. Mean change in SeBP in Hispanics ranged from -15.3/-7.3 mmHg for AML/OM 5/20 mg to -23.2/-13.8 mmHg for AML/OM 10/40 mg + hydrochlorothiazide 25 mg, and in non-Hispanics from -14.1/-7.8 mmHg to -25.4/-13.7 mmHg (all p < 0.0001 versus baseline). A majority of patients achieved mean 24 h, daytime, and nighttime ABP targets in both subgroups. Greater proportions of Hispanics achieved ABP targets versus non-Hispanics at week 12; however, this trend was reversed at week 20. Treatment was well tolerated.ConclusionsSwitching to a fixed-dose combination of AML/OM ± hydrochlorothiazide provided significant BP lowering and effectively controlled BP in a large proportion of Hispanic and non-Hispanic patients with hypertension uncontrolled on previous monotherapy.

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:BackgroundHypertension is often inadequately controlled in older people.ObjectiveThis prespecified subgroup analysis assessed the efficacy and safety of an olmesartan medoxomil (OM) 40 mg/amlodipine besylate (AML) 10 mg/hydrochlorothiazide (HCTZ) 25 mg triple-combination treatment compared with the 3 components as dual-combination treatments in participants with hypertension who were <65 and ≥ 65 years of age. Within the ≥ 65 years of age subgroup, efficacy and safety were also summarized for participants ≥ 75 years of age.Study design12-week, multicenter, double-blind, randomized, parallel-group study.Setting317 ambulatory care sites in the US and Puerto Rico.ParticipantsIndividuals ≥ 18 years of age with mean seated blood pressure (SeBP) ≥ 140/100 or ≥ 160/90 mmHg off antihypertensive medication on 2 consecutive clinic visits with no recent history of significant cerebrovascular disease, coronary artery disease, heart failure (New York Heart Association class III or IV), severe renal insufficiency, or uncontrolled diabetes (HbA1c >9 %).InterventionParticipants were randomized, stratified by age, diabetes status, and race to one of four treatment assignments: OM 40/AML 10/HCTZ 25 mg, OM 40/AML 10 mg, OM 40/HCTZ 25 mg, or AML 10/HCTZ 25 mg.Main outcome measureLeast squares (LS) mean change from baseline in seated diastolic blood pressure (SeDBP) at week 12 (last observation carried forward) in each age subgroup (prespecified analysis).ResultsOf the 2492 randomized participants in the study (total cohort), 2021 (81.1 %) were <65 and 471 (18.9 %) were ≥ 65 years of age, including 79 (3.2 %) who were ≥ 75 years of age. OM 40/AML 10/HCTZ 25 mg triple-combination treatment resulted in a significantly greater reduction in LS mean SeDBP at week 12 than dual-combination component treatments in participants in both cohorts: <65 years (21.0 vs. 14.2-17.2 mmHg; p < 0.0001) and ≥ 65 years (23.7 vs. 17.3-20.0 mmHg; p ≤ 0.002). Similarly, triple-combination treatment resulted in a greater reduction in LS mean seated systolic blood pressure (SeSBP) at week 12 than dual-combination component treatments: <65 years (38.2 vs. 28.3-31.4 mmHg; p < 0.0001) and ≥ 65 years (39.2 vs. 29.3-31.1 mmHg; p < 0.0001). Triple-combination treatment was more effective than dual-combination treatments in enabling participants to reach SeBP goal (<140/90 mmHg [<130/80 mmHg in participants with diabetes, chronic kidney disease, or chronic cardiovascular disease]) in both age subgroups (<65 years: 65 vs. 34-50 %, respectively, p < 0.0001 and ≥ 65 years: 63 vs. 32-39 %; p ≤ 0.0004). All 4 treatments were safe and well tolerated with low discontinuation rates in both age subgroups. There were no clinically relevant differences in the incidence of treatment-emergent adverse events between participants <65 and ≥ 65 years of age receiving triple-combination treatment.ConclusionTriple-combination treatment with OM 40/AML 10/HCTZ 25 mg was well tolerated and more effective in lowering BP than the component dual-combination treatments in elderly and non-elderly subgroups.

Project description:IntroductionCentral blood pressure (BP), an important measure of cardiovascular risk, has been shown to be effectively reduced by calcium channel blockade with amlodipine (AML) plus renin-angiotensin system blockade by the angiotensin-converting enzyme inhibitor, perindopril (PER). The aim of the SEVITENSION study was to compare the central effects of PER/AML against renin-angiotensin system blockade with the angiotensin II receptor blocker olmesartan (OLM) plus AML.MethodsIn this multicenter, parallel group, non-inferiority study, patients received AML 10 mg during a 2- to 4-week run-in before randomization to 24 weeks of double-blind treatment with the fixed-dose combination of OLM/AML 40/10 mg or PER/AML 8/10 mg. Hydrochlorothiazide was added at Weeks 4, 8, or 12 in patients with inadequate BP control. The primary efficacy variable was the absolute change in central systolic BP (CSBP) from baseline to the final examination, measured by radial artery applanation tonometry and analyzed by parametric analysis of covariance. Secondary variables included 24-h ambulatory and seated BP measurements as well as BP normalization.ResultsOf 600 patients enrolled, 486 were randomized (244 to OLM/AML 40/10 mg, 242 to PER/AML 8/10 mg). The reduction in CSBP was larger with OLM/AML (14.5 ± 0.83 mmHg) than with PER/AML (10.4 ± 0.84 mmHg). The between-group difference was -4.2 ± 1.18 mmHg with 95% confidence intervals (-6.48 to -1.83 mmHg) within the predefined non-inferiority margin (2 mmHg). An integrated superiority test confirmed that OLM/AML was superior to PER/AML (p < 0.0001) in reducing CSBP. The superiority of OLM/AML over PER/AML was also established for the majority of secondary efficacy variables; at the final examination, 75.6% of OLM/AML recipients achieved BP normalization (mean seated systolic BP/diastolic BP <140/90 mmHg) compared with 57.5% of PER/AML recipients (p < 0.0001).ConclusionThe combination of OLM/AML was superior to PER/AML in reducing CSBP and other efficacy measures, including a significantly higher rate of BP normalization.
