Efficacy and Tolerability of Telmisartan/Amlodipine and Rosuvastatin Coadministration in Hypertensive Patients with Hyperlipidemia: A Phase III, Multicenter, Randomized, Double-blind Study.

PURPOSE: Dyslipidemia and hypertension increase the risk for cardiovascular disease. Combination therapy improves patient compliance. This study was conducted to compare the efficacy and tolerability of the combination therapies telmisartan/amlodipine + rosuvastatin, telmisartan/amlodipine, and telmisartan + rosuvastatin in patients with hypercholesterolemia and hypertension. METHODS: In this Phase III, multicenter, 8-week randomized, double-blind study, participants with hypertension and dyslipidemia (defined as a sitting systolic blood pressure [sitSBP] of ≥140 mm Hg, a low-density lipoprotein-cholesterol [LDL-C] level of ≤250 mg/dL, and a triglyceride level of ≤400 mg/dL) were screened. After a 4-week washout/run-in period involving therapeutic lifestyle changes and telmisartan 80 mg once a day, eligible patients had a sitSBP of ≥140 mm Hg and met the LDL-C level criteria according to the National Cholesterol Education Program Adult Treatment Panel III cardiovascular disease risk category. Patients were randomly assigned to 1 of 3 groups: (1) telmisartan/amlodipine 80/10 mg + rosuvastatin 20 mg (TAR group); (2) telmisartan/amlodipine 80/10 mg (TA group); or (3) telmisartan 80 mg + rosuvastatin 20 mg (TR group). The primary efficacy end points were the percentage changes from baseline in LDL-C in the TAR and TA groups and the mean changes in sitSBP in the TAR and TR groups at week 8 compared to baseline. Continuous variables were compared using the unpaired t test or the Wilcoxon rank sum model, and categorical variables were compared using the χ2 or Fisher exact test. Tolerability was assessed based on adverse events found on physical examination including vital sign measurements, laboratory evaluations, and 12-lead ECG. FINDINGS: A total of 134 patients were enrolled. The least squares mean percentage changes in LDL-C at 8 weeks after administration of the drug compared to baseline were -51.9% (3.0%) in the TAR group and -3.2% (2.9%) in the TA group (P < 0.001). At 8 weeks after baseline, the least squares mean (SE) changes sitSBP were -28.3 (2.4) mm Hg in the TAR group and -10.7 (2.1) mm Hg in the TR group (P < 0.001). The prevalence rates of treatment-emergent adverse events were 15.0%, 25.0%, and 12.2% in the TAR, TA, and TR groups, respectively; those of adverse drug reactions were 15.0%, 22.7%, and 10.2%. None of the differences in rates were significant among 3 groups. IMPLICATIONS: Triple therapy with TAR can be an effective treatment in patients with dyslipidemia and hypertension. The TAR combination has value for hypertensive patients with hyperlipidemia in terms of convenience, tolerability, and efficacy. ClinicalTrials.gov identifier: NCT03566316.

A Phase III, Multicenter, Randomized, Double-blind, Active Comparator Clinical Trial to Compare the Efficacy and Safety of Combination Therapy With Ezetimibe and Rosuvastatin Versus Rosuvastatin Monotherapy in Patients With Hypercholesterolemia: I-ROSETTE (Ildong Rosuvastatin & Ezetimibe for Hypercholesterolemia) Randomized Controlled Trial.

PURPOSE: Combination therapy with ezetimibe and statins is recommended in cases of statin intolerance or insufficiency. The objective of this study was to compare the efficacy and safety of combination therapy with ezetimibe and rosuvastatin versus those of rosuvastatin monotherapy in patients with hypercholesterolemia. METHODS: I-ROSETTE (Ildong ROSuvastatin & ezETimibe for hypercholesTElolemia) was an 8-week, double-blind, multicenter, Phase III randomized controlled trial conducted at 20 hospitals in the Republic of Korea. Patients with hypercholesterolemia who required medical treatment according to National Cholesterol Education Program Adult Treatment Panel III guidelines were eligible for participation in the study. Patients were randomly assigned to receive ezetimibe 10 mg/rosuvastatin 20 mg, ezetimibe 10 mg/rosuvastatin 10 mg, ezetimibe 10 mg/rosuvastatin 5 mg, rosuvastatin 20 mg, rosuvastatin 10 mg, or rosuvastatin 5 mg in a 1:1:1:1:1:1 ratio. The primary end point was the difference in the mean percent change from baseline in LDL-C level after 8 weeks of treatment between the ezetimibe/rosuvastatin and rosuvastatin treatment groups. All patients were assessed for adverse events (AEs), clinical laboratory data, and vital signs. FINDINGS: Of 396 patients, 389 with efficacy data were analyzed. Baseline characteristics among 6 groups were similar. After 8 weeks of double-blind treatment, the percent changes in adjusted mean LDL-C levels at week 8 compared with baseline values were -57.0% (2.1%) and -44.4% (2.1%) in the total ezetimibe/rosuvastatin and total rosuvastatin groups, respectively (P < 0.001). The LDL-C-lowering efficacy of each of the ezetimibe/rosuvastatin combinations was superior to that of each of the respective doses of rosuvastatin. The mean percent change in LDL-C level in all ezetimibe/rosuvastatin combination groups was >50%. The number of patients who achieved target LDL-C levels at week 8 was significantly greater in the ezetimibe/rosuvastatin group (180 [92.3%] of 195 patients) than in the rosuvastatin monotherapy group (155 [79.9%] of 194 patients) (P < 0.001). There were no significant differences in the incidence of overall AEs, adverse drug reactions, and serious AEs; laboratory findings, including liver function test results and creatinine kinase levels, were comparable between groups. IMPLICATIONS: Fixed-dose combinations of ezetimibe/rosuvastatin significantly improved lipid profiles in patients with hypercholesterolemia compared with rosuvastatin monotherapy. All groups treated with rosuvastatin and ezetimibe reported a decrease in mean LDL-C level >50%. The safety and tolerability of ezetimibe/rosuvastatin therapy were comparable with those of rosuvastatin monotherapy. ClinicalTrials.gov identifier: NCT02749994.

Efficacy and Tolerability of Telmisartan/Amlodipine + Hydrochlorothiazide Versus Telmisartan/Amlodipine Combination Therapy for Essential Hypertension Uncontrolled With Telmisartan/Amlodipine: The Phase III, Multicenter, Randomized, Double-blind TAHYTI Study.

PURPOSE: This 8-week study in Korea aimed to evaluate the efficacy and tolerability of a telmisartan/amlodipine + hydrochlorothiazide (TAH) combination versus telmisartan/amlodipine (TA) combination in patients with essential hypertension that did not respond appropriately to 4-week treatment with TA. METHODS: All patients who met the inclusion criteria received TA (40/5 mg) during a 4-week run-in period (period 1). Patients who met the criteria for essential hypertension (mean sitting systolic blood pressure [MSSBP], ≥140 and <200 mm Hg, or ≥130 and<200 mm Hg in those with diabetes mellitus or chronic kidney disease) after period 1 were randomly assigned to receive TA 40/5 mg + hydrochlorothiazide 12.5 mg (test group) or TA only (control group). The test and control drugs were administered in each group for 2 weeks (period 2). Patients who completed period 2 underwent 6-week treatment (period 3) with a TAH and TA dose twice that in period 2. The primary end point was the change in MSSBP at week 8 of treatment. Secondary end points were the change in MSSBP at week 2 and MS diastolic BP, BP control rate, and BP response rate at weeks 2 and 8. Treatment tolerability was assessed based on adverse events (AEs), laboratory evaluations (chemistry, hematology, and urinalysis), 12-lead ECG, and physical examination including vital sign measurements. FINDINGS: We randomized 310 patients to the treatment groups. The mean (SD) ages of the TAH and TA groups were 62.0 (10.8) and 63.4 (10.4) years, respectively. The least squares mean change in MSSBP was significantly greater in the TAH group than in the TA group after 8 weeks (-18.7 vs -12.2 mm Hg; P < 0.001). Similar results were obtained on changes in MSSBP after 2 weeks and changes in sitting diastolic BP, BP control rate, and BP response rate at weeks 2 and 8 compared with the respective baseline values. The prevalences of treatment-emergent AEs (29.0% vs 16.3%; P = 0.008) and adverse drug reactions (20.0% vs 10.5%; P = 0.020) were significantly greater in the TAH group than in the TA group. Most treatment-emergent AEs were mild or moderate; none were severe. The most frequently reported AEs were dizziness and headache. IMPLICATION: TAH triple therapy was more effective than was TA double therapy in reducing BP in these patients in Korea with essential hypertension that did not adequately respond to TA.
