Real-life Effectiveness and Safety of Amlodipine/Valsartan Single-pill Combination in Patients with Hypertension in Egypt: Results from the EXCITE Study.

BACKGROUND: EXCITE (clinical experience of amlodipine and valsartan in hypertension) evaluated the real-world effectiveness and safety of single-pill combinations (SPCs) of amlodipine/valsartan (Aml/Val) and amlodipine/valsartan/hydrochlorothiazide (Aml/Val/HCTZ) in patients with hypertension from the Middle East and Asia.
OBJECTIVE: The objective of this study was to report the results of EXCITE study from Egypt, where all patients were prescribed Aml/Val.
METHODS: This was a 26-week, observational, multicenter, prospective, non-interventional, open-label study. Effectiveness was assessed as change in the mean sitting systolic/diastolic blood pressure (msSBP/msDBP) from baseline and the proportion of patients achieving the therapeutic blood pressure (BP) goal (<140/90; <130/80 mmHg in patients with diabetes mellitus) and BP response (SBP <140 mmHg or reduction of ≥20 mmHg; DBP <90 mmHg or reduction of ≥10 mmHg). Safety was monitored by recording the incidence of adverse events (AEs) and serious AEs (SAEs).
RESULTS: A total of 2566 patients (mean age, 52.6 years; mean duration of hypertension, 7.9 years) were prescribed Aml/Val, of whom 2439 (95.1 %) completed the study. At week 26, Aml/Val SPC significantly (p < 0.0001) reduced msSBP/msDBP by -34.5/-19.4 mmHg from baseline (BP: 164.3/100.5 mmHg). Therapeutic goal, SBP response, and DBP response was achieved by 49.3, 91.1, and 91.4 % of patients, respectively. AEs were reported in 12.5 % of patients, with the most common including peripheral edema (1.8 %), bronchitis (1.1 %), and gastritis (0.8 %), and SAEs in 0.5 % of patients. Two deaths were reported during the study, none of which were considered to be study drug related by the investigators.
CONCLUSION: Aml/Val SPC provided clinically significant BP reductions and was generally well tolerated in patients with hypertension from Egypt.

Key Points

Introduction

Hypertension is an important worldwide health challenge, the prevalence of which has been estimated to rise from 972 million people in the year 2000 to 1.56 billion by 2025 [1]. Of the 1.56 billion people, 1.15 billion will represent the population in economically developing countries, accounting for almost three-fourths of the world’s hypertensive population [1]. High blood pressure (BP) is one of the three leading risk factors contributing to global disease burden, especially in most of Asia, most of Latin America, North Africa, the Middle East, and central Europe, accounting for 9.4 million deaths worldwide in 2010 [2].

Hypertension represents a major public health problem in Egypt. The Egypt Demographic and Health Survey (2008) reported the overall prevalence of hypertension as 17.6 %, which increased with age. Diabetes mellitus, overweight, and obesity were the leading risk factors associated with the increasing prevalence of hypertension. Although the rate of awareness of hypertension was as high as 54.2 and 43.4 % of patients received treatment, BP control was achieved only by 21.3 %, and BP control declined with increasing age [3, 4].

Despite the availability of several antihypertensive agents from different pharmacological classes for the management of hypertension, achieving BP control to the recommended target levels is a challenge worldwide [5, 6]. With monotherapy, only 30 % of patients with hypertension are effectively treated, while the majority fails to achieve recommended BP goals [7]. The 2013 European Society of Hypertension/European Society of Cardiology and the 2013 Egyptian Hypertension Society Guidelines recommend two or more antihypertensive medications to be prescribed as combination therapy to achieve BP control in the majority of patients with hypertension [8, 9]. Blockers of the renin-angiotensin-aldosterone system [angiotensin receptor blocker (ARB) or angiotensin-converting enzyme inhibitor (ACEI)] together with a calcium channel blocker (CCB) and/or a diuretic, which have complementary mechanisms of action, are among the recommended combinations of antihypertensive agents [9]. Further, several studies have shown that fixed-dose single-pill combination (SPC) administration has more benefits than the corresponding free combinations of the same drugs, such as improved compliance and persistence to therapy, decreased incidence of adverse effects, and simplification of the therapeutic regimen. As a consequence of improved compliance, overall efficacy and BP control would also be better with SPCs [10].

Amlodipine/valsartan (Aml/Val) and amlodipine/valsartan/ hydrochlorothiazide (Aml/Val/HCTZ) SPCs demonstrated significant and effective BP lowering and were well tolerated in several clinical studies conducted in patients with stage 1 and/or 2 hypertension [11-13]. Real-life observational studies with the Aml/Val combination reported safe and effective reduction of BP across all hypertension grades as well as in patients with isolated systolic hypertension (ISH), with a majority of the patients attaining BP goals [14, 15]. Studies conducted in a real-life practice setting provide additional evidence to randomized clinical trials and are of greater relevance to routine clinical practice [16].

The EXCITE (clinical experience of amlodipine and valsartan in hypertension) study was performed in a real-world setting to evaluate the effectiveness and safety of Aml/Val and Aml/Val/HCTZ SPCs in patients with hypertension from different developing countries in the Middle East and Asia. Data from each of the above individual countries and the overall pooled data were analyzed to provide a comprehensive overview of the therapies. This article presents the data obtained from patients with hypertension in Egypt and examines if there were any differences in the effectiveness of the Aml/Val SPC at a regional or country level. Such a country-specific analysis provides a closer look into routine clinical practice and can serve as additional evidence to randomized clinical trials.

Additionally, this study presents data derived from specific ethnic populations in the context of hypertension drug therapy, knowing that many therapeutic agents have shown ethnicity-related variations in both efficacy and safety.

Methods

Study Design

The EXCITE study was an observational, multicenter, multinational, prospective, non-interventional, and open-label study conducted in patients with hypertension from 13 countries in the Middle East (Bahrain, Egypt, Kuwait, Lebanon, Oman, Qatar, and United Arab Emirates) and Asia (Indonesia, Hong Kong, Pakistan, Philippines, South Korea, and Taiwan). Patients received treatment with either Aml/Val or Aml/Val/HCTZ SPCs as part of routine care and according to the local prescribing information in the respective participating countries. Data from one umbrella protocol were pooled for analysis from the countries listed above, including Egypt [17].

In Egypt, all patients with hypertension received the Aml/Val SPC (dosages 5/160 or 10/160 mg), either as single therapy or add-on therapy to other antihypertensive medications. As the Aml/Val/HCTZ SPC was not registered in Egypt when the study began, only patients receiving the Aml/Val SPC were enrolled. The data originating from assessments and evaluations performed according to the physician’s routine practice and standard care were collected. The study, along with data collection, commenced in June 2010 and ended in October 2012. There were no additional diagnostic or monitoring procedures beyond usual care. Patient visit intervals were chosen at the physician’s discretion and according to usual care.

The observational period of 26 ± 8 weeks included data from at least two routine examinations for each patient at: baseline, week 13 (optional), and study endpoint (week 26 ± 8 weeks). Demographic and baseline characteristics data of patients including history of hypertension, risk factors, medical history, and use of antihypertensive and other concomitant medications were recorded at study entry.

Patients

Adults (aged ≥18 years) with an established diagnosis of hypertension, for whom SPC treatment with Aml/Val had been prescribed by a treating physician as part of routine patient care, and who consented to data collection, were eligible for inclusion in the study. Patients were excluded from the study if they had any contraindication to Aml/Val as defined in the local prescribing information for their country.

Effectiveness Assessments

Effectiveness was assessed by changes in mean sitting systolic BP (msSBP) and mean sitting diastolic BP (msDBP) from baseline to the end of the study (week 26 ± 8 weeks), and optional data at week 13 were collected. The mean of three sitting BP values were recorded, and BP was measured as per the clinician’s practice. The proportion of patients who achieved the therapeutic BP goal (<140/90; <130/80 mmHg in patients with diabetes) and BP response (SBP <140 mmHg [130 mmHg for patients with diabetes] or a reduction of ≥20 mmHg; DBP <90 mmHg [80 mmHg for patients with diabetes] or a reduction of ≥10 mmHg) was also assessed. Subjective assessment of treatment effectiveness was rated by the treating physician as ‘below average’, ‘average’, ‘good’, and ‘very good’ at the end of the study.

Safety Assessments

Safety assessments included physician monitoring and recording of incidence of all adverse events (AEs), serious adverse events (SAEs), and the incidence of edema. At the end of the study, tolerability and compliance were assessed by the treating physician as ‘below average’, ‘average’, ‘good’, or ‘very good, based on a subjective evaluation scale.

Statistical Analyses

All effectiveness and safety analyses were performed on the full analysis set consisting of patients who provided informed consent and entered the study. Analyses were conducted by treatment cohort only or by treatment cohort and treatment dosage, according to the treatment and dosage the patient was taking at the time of entry into the study. Statistical analysis was performed using version 9.2 of the SAS statistical package. The paired t test was used to assess the change in BP from baseline to the end of the study. In the case of patients who discontinued before week 26, the last observation carried forward (i.e., last available post-baseline value) was considered. The data were presented as mean (95 % confidence interval [CI]).

Subgroup analyses were performed for effectiveness variables in the treatment cohort based on diabetic status, baseline SBP (<140; 140 to <160; 160 to <180 and ≥180 mmHg), age (<65, ≥65 years), sex, ISH at baseline (SBP ≥140 mmHg and DBP <90 mmHg), and body mass index (BMI) at baseline (<30, ≥30 kg/m2).

The incidence of AEs and SAEs was summarized with frequency counts and percentages by preferred term and treatment cohort.

Demographic and baseline characteristics of the patients are presented in Table 1. The mean age was 52.6 (±10.31) years and the mean duration of hypertension was 7.9 (±7.26) years, with a baseline sitting BP of 164.4 (±14.92)/100.5 (±8.63) mmHg. Patients in this study reported the following main cardiovascular risk factors: family history of hypertension (39.5 %), dyslipidemia (39.1 %), diabetes (34.4 %), and coronary heart disease (13.3 %). Prior to study participation, most patients (78.9 %) were taking antihypertensive agents, with the most frequently used classes of antihypertensive medications being selective beta-blockers (24.5 %), ACEIs (20.8 %), dihydropyridine derivatives (15.8 %), and angiotensin II antagonists (10.6 %).

The most common reason for changing previous treatment to receive the Aml/Val SPC was unsatisfactory BP control with prior treatment as reported by 1898 patients (74.0 %), followed by insufficient compliance with prior treatment in 566 patients (22.1 %) and insufficient tolerability of prior treatment in 514 patients (20.0 %). At baseline, 1742 patients (67.9 %) were prescribed Aml/Val 5/160 mg and 824 patients (32.1 %) were prescribed Aml/Val 10/160 mg. At baseline, week 13, and week 26, 662 patients (25.8 %), 347 patients (13.5 %), and 340 patients (13.5 %) received concomitant antihypertensive treatment in addition to the study drug. Selective beta-blockers were the most commonly prescribed medication at baseline, week 13, and week 26.

Effectiveness

Change in BP from Baseline to Endpoint

At week 13, the mean (±standard deviation) reduction observed in mean sitting BP was −28.8 (±15.81)/−16.1 (±9.47) mmHg with the Aml/Val SPC in the overall population (baseline BP, 165.2/100.9 mmHg; n = 2041), −26.9 (±14.83)/−15.5 (±9.55) mmHg with Aml/Val 5/160 mg (baseline BP, 162.8/99.9 mmHg; n = 1390), and −32.9 (±17.03)/−17.4 (±9.16) mmHg with Aml/Val 10/160 mg (baseline BP, 170.1/102.9 mmHg; n = 651). At the week 26 endpoint, Aml/Val showed clinically significant mean [95 % CI reductions (p < 0.0001) from baseline (baseline BP, 164.3/100.5 mmHg) in msSBP (−34.5 mmHg (95 % CI −35.10, −33.85)] and msDBP (−19.4 mmHg [95 % CI −19.79, −19.03]). BP reductions from baseline to week 13 and the study endpoint were greater with the higher dose of Aml/Val (10/160 mg) (Fig. 2).

Reductions in BP from baseline were observed across all the subgroups based on age, sex, BMI, diabetes, and ISH (Table 2). Generally similar reductions were seen regardless of sex and in diverse patient subgroups, such as the older patients (aged ≥65 years), obese patients (BMI ≥30 kg/m2), or patients with diabetes. BP reductions were dependent on the level of baseline SBP, with the greatest reductions observed in patients with baseline SBP ≥180 mmHg (Table 2).

BP Goals and BP Response Rates

At the week 26 endpoint, the proportion of patients achieving the therapeutic BP goal was 49.3 %. SBP and DBP response was achieved by 91.1 and 91.4 % of patients, respectively (Fig. 3). In addition, the proportion of patients who achieved SBP and DBP response in the 5/160 and 10/160 mg Aml/Val dosage categories was almost similar to the response rates achieved in the overall population (Fig. 3). The physicians rated the effectiveness of the antihypertensive therapy as ‘good’ or ‘very good’ for 85 % of patients.

Safety

A total of 322 (12.5 %) patients reported at least one AE during the study period. The most frequent AEs were peripheral edema (1.8 %), bronchitis (1.1 %), and gastritis (0.8 %) (Table 3). The incidence of edema was 15.7 % (402 patients) at baseline and 13.3 % (329 patients) at the end of the study. There were two deaths reported during the study period, neither of which was considered to be related to the study drug by the investigators. A 66-year-old male patient died of heart failure on day 1 of study commencement and a 43-year-old female patient died from unknown causes on day 82. Serious AEs were experienced by 12 patients (0.5 %). Of the SAEs reported, two events, chest tightness on day 8 and renal failure on day 152, were suspected by the investigators to be related to the study drug. The most frequent SAEs were cardiac disorders, reported in five patients (0.2 %).

Discontinuations owing to AEs were reported in 10 patients (0.4 %): peripheral edema in five patients (0.2 %) and acute myocardial infarction, edema, increased blood creatinine, renal failure, and flushing, in one patient each. Both treatment compliance and tolerability were rated by investigators as ‘good’ or ‘very good’ for 88 % of patients.

Discussion

Our study showed that Aml/Val SPC in a real-life setting significantly reduced BP from baseline to the week 26 endpoint in patients with hypertension from Egypt. Dose-dependent BP reductions were observed at weeks 13 and 26, with greater BP reductions correlating with higher baseline SBP at week 26. Almost half of all patients in the study reached the therapeutic BP goal, and the majority of the patients attained SBP and DBP responses. In diverse patient subgroups such as in older patients (aged ≥65 years), obese patients (BMI ≥30 kg/m2), or in patients with comorbid diabetes, similar and consistent reductions in BP were observed and were comparable to the reductions seen in the overall population. In addition, Aml/Val SPC was generally well tolerated in this patient population. Effectiveness, tolerability, and treatment compliance were rated by the physicians as ‘good’ and ‘very good’ for the majority of the patients.

The findings from this study compare well to previously reported real-life studies [14, 15], and seem to be generally consistent with the findings reported in randomized clinical trials evaluating the Aml/Val combination in patients with hypertension [13, 18–21]. In the present study, a dose-dependent decrease in msSBP was observed with Aml/Val, with reductions of −32.6 and −38.5 mmHg for the 5/160- and 10/160-mg doses of Aml/Val, respectively. These results are consistent with previously reported 8-week randomized studies, wherein dose-dependent reductions in BP for the 5/160- and 10/160-mg doses of Aml/Val were observed [21]. The Exforge in Failure After Single Therapy (EX-FAST) study also showed an Aml/Val dose-dependent reduction in BP in patients with hypertension [18].

Our results are very similar to those obtained from other real-world studies with different populations, where significant SBP as well as DBP reductions of 33–36 mmHg and 16–18 mmHg, respectively, with the Aml/Val free-dose combination (5/80, 10/160 mg) and the Aml/Val SPC (5/80, 5/160, or 10/160 mg) were observed [14, 15]. These real-world studies also demonstrated dose-dependent, BP-lowering effects and greater BP-lowering effects with increasing severity of baseline SBP. It is important to note that the baseline BP of the patient populations in both these studies (baseline BP ranging from 163.1 to 165.0/96.2 to 99.3 mmHg) is very similar to that of the current study’s patient cohort (baseline BP, 164.3/100.5 mmHg). Similar to the results of the current study, data from a recent 12-week real-life study conducted in Egyptian patients with hypertension reported that Aml/Val SPC resulted in significant mean BP reductions of −39.4/−21.7 mmHg (p < 0.001) at the end of the study (baseline BP, 171.5/103.4 mmHg). In addition, dose-dependent BP lowering was observed with Aml/Val doses of 5/160 and 10/160 mg, with a comparable BP reduction of −34.6/−19.2 mmHg with 5/160 mg Aml/Val [22]. BP reductions observed in this study are greater than the BP-lowering effect reported by the EXCITE study in patients with hypertension from Pakistan (−24.5/−12.7 mmHg; baseline BP: 153.4/91.1 mmHg), and the overall EXCITE study results (−31.0/−16.6 mmHg; baseline BP: 160.9/97.1 mmHg) [17, 23]. The differences in BP reductions between the current study and the data of EXCITE studies from other countries might be owing to differences in the study population as well as in the baseline BP. In this study, BP reductions observed were consistent across patient subgroups, regardless of age, diabetic status, sex, and BMI, and were generally similar to previously reported controlled efficacy studies conducted in various subgroups studied [19, 20, 24].

Achievement of the therapeutic BP goal continues to remain a challenge for most patients receiving antihypertensive therapy [25]. In this study, more than 90 % of all patients achieved the BP response with Aml/Val SPC treatment, and BP control was achieved in almost 50 % of patients. Of note, this study included diverse patient sub-groups (older patients, 11.2 %; obese patients, 46.3 %; and patients with diabetes, 34.4 %), in whom achieving the target BP goals and responses is difficult.

Lack of adherence to antihypertensive therapy is a potential reason for patients not achieving BP goals. Previous findings on the use of Aml/Val SPC in a real-world setting showed better treatment adherence and persistence, and lower healthcare costs and utilization, relative to free combinations of ARB plus CCB among patients with hypertension [26]. In our study, the treatment compliance was assessed by physicians to be ‘good’ or ‘very good’ for 88 % of patients.

The safety profile of the Aml/Val combination in this real-life study was consistent with previously reported randomized and real-life studies on Aml/Val [13, 14, 18, 21, 22]. Edema is a well-documented AE of CCBs that is commonly reported with amlodipine. The incidence of edema was less in this study, and these results are in agreement with other real life studies that have reported lowering of edema upon combining CCBs with ACEIs or ARBs [14, 15].

This study has inherent limitations with respect to interpretation of its results as it is an observational, open-label, non-randomized, non-controlled study by design, and caution needs to be employed while deriving conclusions. The findings of this study are restricted to the cohort investigated here and cannot be extended to other patient populations. The real-life setting of our study does not permit us to make decisive conclusions on comparative efficacy and safety of the Aml/Val SPC. Another limitation of the study is that the addition of Aml/Val SPC to other antihypertensive therapies might have contributed to an increase in the treatment efficacy and this influence has not been analyzed. An additional limitation is the use of subjective evaluation scales for the physicians’ assessment of effectiveness, tolerability, and treatment compliance in this study. However, owing to its strength as an observational study by design with a large sample size, data could be obtained from diverse patient populations with hypertension, thereby making the results of this study more relevant to clinical practice in a real-life setting.

Conclusion

In this observational study conducted in patients with hypertension from Egypt, Aml/Val SPC provided statistically significant reductions in BP from baseline to week 26. In addition, Aml/Val was generally well tolerated. Thus, the results of the EXCITE study provide evidence from a real-world setting that Aml/Val SPC is effective and well tolerated in patients with hypertension from Egypt.

This real-world study conducted in Egypt showed that a single-pill combination of amlodipine and valsartan was effective in reducing blood pressure and was well tolerated in patients with hypertension.

The present findings related to effectiveness and safety compare well with previously reported real-life studies and are consistent with the findings derived from randomized clinical trials evaluating the amlodipine/valsartan combination in patients with hypertension.

The diversity of the patient sub-groups (older patients, obese patients, and patients with diabetes mellitus), adds to the clinical implications of the present results.
