Efficacy and safety of standard dose triple combination of telmisartan 80 mg/amlodipine 5 mg/chlorthalidone 25 mg in primary hypertension: A randomized, double-blind, active-controlled, multicenter phase 3 trial.

ABSTRACT: The authors evaluated the efficacy, safety, and characteristics of patients who respond well to standard dose triple combination therapy including chlorthalidone 25 mg with telmisartan 80 mg plus amlodipine 5 mg in hypertensive patients. This is a multicenter, double-blind, active-controlled, phase 3, randomized trial. Patients are randomized to triple combination (telmisartan 40 mg/amlodipine 5 mg/chlorthalidone 12.5 mg, TEL/AML/CHTD group) or dual combination (telmisartan 40 mg/amlodipine 5 mg, TEL/AML group) treatment and then dose up titration to TEL 80/AML5/CHTD25mg and TEL80/AML5, respectively. The primary endpoint is the change of mean sitting systolic blood pressure (MSSBP) at week 8. A Target BP achievement rate, a response rate, and the safety endpoints are also evaluated. Total 374 patients (mean age = 60.9 ± 10.7 years, male = 78.3%) were randomized to the study. The baseline MSSBPs/diastolic BPs were 149.9 ± 12.2/88.5 ± 10.4 mm Hg. After 8 weeks treatment, the change of MSSBPs at week 8 are -19.1 ± 14.9 mm Hg (TEL/AML/CHTD) and -11.4 ± 14.7 mm Hg (TEL/AML) (p < .0001). The achievement rates of target BP (53.8% vs. 37.8%, p = .0017) and responder rate (54.8% vs. 35.6%, p = .0001) at week 8 were significantly higher in TEL/AML/CHTD. There are no serious adverse event and no one discontinued medication due to adverse event. Among the TEL 80/AML5/CHTD25mg treatment group, patients of female or age ≥ 65 years old showed higher rate of target BP achievement than relatively young male. (61.4 vs. 46.8%, p = .042) Our study showed standard dose triple combination of telmisartan 80 mg/amlodipine 5 mg/chlorthalidone 25 mg is efficacious and safe in treatment of primary hypertension. Target BP achievement with triple therapy would be facilitated in female or old age.

Project description:BackgroundThe efficacy of a combination of a calcium channel blocker (CCB) plus chlorthalidone (diuretic) versus a CCB plus an angiotensin receptor blocker (ARB) in patients not responding to CCB monotherapy has not been evaluated previously. We plan to compare the efficacy and safety of S-amlodipine (CCB) plus chlorthalidone versus S-amlodipine plus telmisartan (ARB) combinations among hypertension patients unresponsive to amlodipine monotherapy.Methods/designThis study is a prospective, randomized, double-blind, multicenter, parallel, non-inferiority phase 4 study. Hypertension patients who have been treated with amlodipine (5 mg) or S-amlodipine (2.5 mg) monotherapy for ≥2 weeks and whose mean diastolic blood pressure (DBP) is greater than 90 mmHg will be randomized to either S-amlodipine (2.5 mg) plus chlorthalidone (25 mg) or S-amlodipine (2.5 mg) plus telmisartan (40 mg) therapy. The primary efficacy endpoint is mean sitting DBP change after 12 weeks of treatment. The study objective is to prove the non-inferiority of the former combination (test drug) as compared to the latter one (control) with a non-inferiority margin of 3 mmHg in mean DBP change. The secondary endpoints are 6-week DBP change, 6- and 12-week sitting systolic BP (SBP) change, and the attainment of the target BP (SBP < 140 mmHg or DBP < 90 mmHg). Urine albumin, albumin/creatinine ratio (ACR), pulse wave velocity, central BP, 24-h ambulatory BP monitoring, and body fluid composition analysis will be performed at each hospital's discretion. The sample size was estimated as 170 in total with 1:1 randomization.DiscussionThis is the first study comparing the efficacy of a CCB plus chlorthalidone versus a CCB plus an ARB in patients who are not responding to CCB single therapy. The study result will help clinicians to choose between chlorthalidone and telmisartan in CCB-unresponsive patients.Trial registrationClinicalTrials.gov , NCT03226340. Registered on 2 December 2015.

Project description:BackgroundHypertension and dyslipidemia significantly contribute to cardiovascular disease development. Their coexistence poses challenges in managing multiple medications, influencing treatment adherence.ObjectiveThis study aimed to assess the efficacy and safety of a combined treatment approach using a fixed-dose combination therapy.MethodsThis multicenter, 8-week, randomized, double-blind, Phase IV trial was named Telmisartan/Amlodipine/Rosuvastatin from Samjin Pharmaceuticals and evaluated the efficacy and safety of fixed-dose combination treatment in patients with essential hypertension and dyslipidemia. They were randomly assigned to 2 fixed-dose combination therapy groups, telmisartan 40 mg/amlodipine 5 mg/rosuvastatin 10 mg (TEL/ALD/RSV) or amlodipine 5 mg/atorvastatin 10 mg (ALD/ATV) after washout/run-in period. The primary outcomes were the change in mean sitting systolic blood pressure and the percentage change of LDL-C after 8 weeks of medical treatment. Adverse drug reactions and events were assessed.ResultsOf a total of 304 patients who underwent screening, 252 were randomized to the TEL/ALD/RSV group (125 patients) and the ALD/ATV group (127 patients). The mean (SD) ages of the TEL/ALD/RSV group and the ALD/ATV group were 67.4 (11.3) and 68.2 (10.6) years, respectively (P = 0.563). The least-squares mean (SE) in mean sitting systolic blood pressure changes between the 2 groups were -16.27 (0.93) mm Hg in the TEL/ALD/RSV group, -6.85 (0.92) mm Hg in the ALD/ATV group (LSM difference = -9.42 mm Hg; 95% CI, -11.99 to -6.84; P < .001). For LDL-C level changes, a significant difference was noted between the 2 groups: -50.03% (1.18%) in the TEL/ALD/RSV group, -39.60% (1.17%) in the ALD/ATV group (LSM difference = -10.43%; 95% CI, -13.70 to -7.16; P < .001). No severe adverse events were observed.ConclusionsTEL/ALD/RSV proved to be more efficient than ALD/ATV in lowering blood pressure and reducing LDL-C levels among patients with hypertension and dyslipidemia, with no notable safety concerns.

Project description:BackgroundTwo 8-week, randomized, double-blind, controlled studies previously evaluated the efficacy and tolerability of single-pill combinations of telmisartan 40-80 mg/amlodipine 5-10 mg (T40-80/A5-10) in patients with hypertension not at diastolic blood pressure (DBP) goal (DBP <90 mm Hg) after 6 weeks of amlodipine 5 mg monotherapy (A5) (TEAMSTA-5) or amlodipine 10 mg monotherapy (A10) (TEAMSTA-10). The long-term (≥6 months) tolerability and efficacy of single-pill combinations of T40-T80/A5-A10 have now been evaluated in 2 open-label studies in patients who had successfully completed either TEAMSTA-5 or TEAMSTA-10 (TEAMSTA-5 and TEAMSTA-10 Follow-Ups).MethodsIn the TEAMSTA-5 Follow-Up, 976 patients whose blood pressure was not initially controlled by taking A5 received T40/A5 for 4 or 8 weeks, with consecutive uptitration to T80/A5 if DBP was ≥90 mm Hg. In TEAMSTA-10 Follow-Up, 838 patients not initially achieving blood pressure control using A10 received T40/A10 for 4 weeks before randomization to T40/A10 or T80/A10; after 4 weeks, patients randomized to T40/A10 with DBP ≥90 mm Hg were uptitrated to T80/A10. In both studies, add-on antihypertensive medication was allowed if DBP was not at goal.ResultsTreatment compliance in both follow-up studies was ≥98.4%. Single-pill combinations of T40-T80/A5-A10 resulted in additional clinically relevant blood pressure reductions and 67% to 93% of patients achieved DBP goal (<90 mm Hg); only 1% to 19% of patients received additional medication for hypertension, of whom 29% to 76% achieved DBP goal. Long-term treatment with T40-T80/A5-A10 was well tolerated, with comparable adverse event profiles for all telmisartan/amlodipine combinations. The most common drug-related adverse events were peripheral edema (1.9%-3.9%) and dizziness (1.5% in the T80/A5 group only); these were consistent with the known tolerability profiles of telmisartan/amlodipine combinations. Overall treatment discontinuation rates due to adverse events were low (0.7%-1.5%).ConclusionsIn patients not achieving DBP goal with either A5 or A10 monotherapy, the vast majority achieved DBP goal with single-pill combinations of T40-T80/A5-A10. Long-term treatment was well tolerated with high compliance, promoting treatment adherence regardless of telmisartan/amlodipine dose.

Project description:BackgroundThe purpose of this work was to describe the efficacy and safety of a telmisartan 80 mg + hydrochlorothiazide 25 mg (T80/H25) single-pill combination therapy in patients with moderate-severe hypertension (mean seated trough cuff systolic blood pressure [BP] ≥ 160 mmHg and diastolic BP ≥ 100 mmHg) in specific patient subpopulations.MethodsThis was a planned analysis of a double-blind, multicenter, parallel-group trial that demonstrated the superiority of a single-pill combination of T80/H25 versus T80 monotherapy in terms of systolic BP change from baseline to week 7. Subpopulations included older (aged ≥ 65 years) versus younger, gender, race, hypertension severity, and prior antihypertensive therapy. Endpoints were change from baseline in mean seated trough cuff systolic and diastolic BP, proportion of patients achieving their BP goal (systolic/diastolic BP < 140/90 mmHg), and proportion of patients attaining systolic BP reductions of >30 mmHg and >40 mmHg.ResultsAcross all subgroups, the T80/H25 single-pill combination provided consistently greater systolic and diastolic BP reductions than T80 and more patients had systolic BP reductions of >30 mmHg. In the T80 and T80/H25 groups, BP control was achieved in 34.1% and 48.8% of men, 35.5% and 62.7% of women, 34.5% and 56.6% of Asians, 22.6% and 38.6% of blacks, 36.7% and 57.8% of whites, 36.9% and 57.5% of patients < 65 years, 29.3% and 49.3% ≥65 years, 44.2% and 66.2% of those with grade 2 hypertension, 20.4% and 39.4% of those with grade 3 hypertension, 38.9% and 53.2% of previously untreated patients, 38.1% and 62.5% of patients previously treated with one antihypertensive, and 29.7% and 48.9% of patients previously treated with two or more antihypertensive agents respectively. Treatment was generally well tolerated across the patient subgroups.ConclusionThe T80/H25 single-pill combination provides consistent BP reductions and higher goal attainment rates versus T80 across a range of hypertensive patient subgroups, which are likely to have a positive impact on patients' cardiovascular risk.

Project description:PurposeTo evaluate the blood pressure (BP) lowering efficacy and safety of CKD-828, a fixed-dose combination of S-amlodipine (the more active isomer of amlodipine besylate, which is calcium channel blocker) and telmisartan (long acting angiotensin receptor blocker), in patients with hypertension inadequately controlled with S-amlodipine monotherapy.Patients and methodsEligible patients (N=187) who failed to respond after 4-week S-amlodipine 2.5 mg monotherapy (sitting diastolic blood pressure [sitDBP] ≥90 mmHg) to receive CKD-828 2.5/40 mg (n=63), CKD-828 2.5/80 mg (n=63), or S-amlodipine 2.5 mg (n=61) for 8 weeks. The primary efficacy endpoint, mean sitDBP change from baseline to Week 8, was compared between the combination (CKD-828 2.5/40 mg and CKD-828 2.5/80 mg) and S-amlodipine monotherapy groups. The safety was assessed based on adverse events, vital signs, and physical examination findings.ResultsAfter the 8-week treatment, changes in sitDBP/systolic BP (SBP) were -9.67±6.50/-12.89±11.78, -10.72±6.19/-13.79±9.41, and -4.93±7.26/-4.55±11.27 mmHg in the CKD-828 2.5/40 mg (P<0.0001/P<0.0001), CKD-828 2.5/80 mg (P<0.0001/P<0.0001), and S-amlodipine 2.5 mg (P<0.0001/P=0.0027) groups, respectively, which were all significant BP reductions. At Week 8, the CKD-828 2.5/40 mg (sitDBP/SBP: P=0.0002/P<0.0001) and CKD-828 2.5/80 mg (sitDBP/SBP: P=0.0001/P<0.0001) showed superior BP-lowering effects to S-amlodipine 2.5 mg (P<0.001). At Week 4, all groups showed significant antihypertensive effects but both CKD-828 combinations (CKD-828 2.5/40 mg and CKD-828 2.5/80 mg) exhibited superior BP-lowering effects to that of S-amlodipine 2.5 mg (sitDBP/SBP: P=0.0028/P=0.0001 and P<0.0001/P=0.0012, respectively). The adverse event incidence was significantly lower in the CKD-828 2.5/40 mg (9.52%, P=0.0086) than in the S-amlodipine 2.5 mg group (27.87%) and increasing the telmisartan dose induced no unexpected adverse events, suggesting the safety of CKD-828.ConclusionCKD-828 is an effective and safe option for patients with inadequate responses to S-amlodipine monotherapy.
