Efficacy and Safety Study of Olmesartan Medoxomil, Amlodipine, and Hydrochlorothiazide Combination Therapy in Patients with Hypertension Not Controlled with Olmesartan Medoxomil and Hydrochlorothiazide Combination Therapy: Results of a Randomized, Double-Blind, Multicenter Trial.

ABSTRACT: This 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).In 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.A 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.In 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:Patients with hypertension and cardiovascular disease (CVD), diabetes, or chronic kidney disease (CKD) usually require two or more antihypertensive agents to achieve blood pressure (BP) goals.The efficacy/safety of olmesartan (OM) 40 mg, amlodipine besylate (AML) 10 mg, and hydrochlorothiazide (HCTZ) 25 mg versus the component dual-combinations (OM 40/AML 10 mg, OM 40/HCTZ 25 mg, and AML 10/HCTZ 25 mg) was evaluated in participants with diabetes, CKD, or chronic CVD in the Triple Therapy with Olmesartan Medoxomil, Amlodipine, and Hydrochlorothiazide in Hypertensive Patients Study (TRINITY). The primary efficacy end point was least squares (LS) mean reduction from baseline in seated diastolic BP (SeDBP) at week 12. Secondary end points included LS mean reduction in SeSBP and proportion of participants achieving BP goal (<130/80 mm Hg) at week 12 (double-blind randomized period), and LS mean reduction in SeBP and BP goal achievement at week 52/early termination (open-label period).At week 12, OM 40/AML 10/HCTZ 25 mg resulted in significantly greater SeBP reductions in participants with diabetes (-37.9/22.0 mm Hg vs -28.0/17.6 mm Hg for OM 40/AML 10 mg, -26.4/14.7 mm Hg for OM 40/HCTZ 25 mg, and -27.6/14.8 mm Hg for AML 10/HCTZ 25 mg), CKD (-44.3/25.5 mm Hg vs -39.5/23.8 mm Hg for OM 40/AML 10 mg, -25.3/17.0 mm Hg for OM 40/HCTZ 25 mg, and -33.4/20.6 mm Hg for AML 10/HCTZ 25 mg), and chronic CVD (-37.8/20.6 mm Hg vs -31.7/18.2 mm Hg for OM 40/AML 10 mg, -30.9/17.1 mm Hg for OM 40/HCTZ 25 mg, and -27.5/16.1 mm Hg for AML 10/HCTZ 25 mg) (P<0.05 for all subgroups vs dual-component treatments). BP goal achievement was greater for participants receiving triple-combination treatment compared with the dual-combination treatments, and was achieved in 41.1%, 55.0%, and 38.9% of participants with diabetes, CKD, and chronic CVD on OM 40/AML 10/HCTZ 25 mg, respectively. At week 52, there was sustained BP lowering with the OM/AML/HCTZ regimen. Overall, the triple combination was well tolerated.In patients with diabetes, CKD, or chronic CVD, short-term (12 weeks) and long-term treatment with OM 40/AML 10/HCTZ 25 mg was well tolerated, lowered BP more effectively, and enabled more participants to reach BP goal than the corresponding 2-component regimens.

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.
