Clinical Trial Summary

To evaluate the efficacy and safety of amlodipine besylate and candesartan cilexetil administered in a fixed-dose combination tablet versus co-administered as their separate formulations in patients with essential hypertension who have shown inadequate response on monotherapy of amlodipine or candesartan cilexetil or who are with blood pressure adequately controlled by co-administration of amlodipine besylate and candesartan cilexetil single agents

- Serum creatinine > 1.5 x ULN

- Serum potassium < 3.5 mmol/L or >5.5 mmol/L

19. History of hypersensitivity to ARBs or dihydropyridines

20. History of angioedema to treatment with ACE inhibitors or ARBs

21. Pregnant or lactating women and female volunteers of childbearing potential (except for women who are surgically sterile) who are not willing to use an adequate method of contraception (oral contraceptives, intrauterine device, condom, etc.) during the study. Women of childbearing potential who are not surgically sterile will be allowed to participate in the study only if they have negative pregnancy test at Visit 1 (screening) and should continue to use medically acceptable method of contraception (basic body temperature method and rhythm method will not be allowed). Women with no menses for = 12 months will be considered as postmenopausal state and method of contraception using hormonal contraception such as oral contraceptive should be initiated from or prior to the screening.

22. History of drug or alcohol abuse within recent 1 year

23. Patients having received any other investigational product within recent 12 weeks

24. Conditions which render a subject ineligible for the study at the discretion of the investigator

Outcome

Type Measure Description Time frame Safety issue
Other Adverse events All patients treated with the investigational product will be included in the safety analyses. For adverse events, adverse drug reactions and serious adverse events, the number of subjects experiencing the events or reactions, 95% 2-sided CI, incidence rate, and number of the events or reactions will be presented by treatment arm. The difference in the incidence between the treatment arms will be tested using the ?2 test or Fisher's exact test. The incidence and percentage of events by severity, causality, actions taken and outcome will be presented by treatment arm.
All AEs will be coded per system organ class (SOC) and preferred term (PT) using the MedDRA; for each coded event, the number and percentage of subjects and the number of cases will be summarized by treatment arm. In addition, for each coded event, the number and percentage of subjects by severity, causality, actions taken and outcome will be presented by treatment arm.
Baseline, Week 4 and Week 8
Other Clinical laboratory tests For continuous variables in clinical laboratory test items, the mean, standard deviation, minimum and maximum of baseline value, post-baseline values and change form baseline to post-baseline will be presented by treatment arm. The difference in change from baseline to post-baseline between treatment arms will be tested using the unpaired t-test or Wilcoxon's rank sum test depending on the normality. The intra-arm change from baseline to post-baseline will be tested using the paired t-test or Wilcoxon's signed rank test depending on the normality. For categorical variables, the shift table for frequency and percentage will be presented. The difference in the percentage of subjects whose test results changed from 'normal' to 'abnormal' between treatment arms will be tested using the ?2 test or Fisher's exact test. The intra-arm change from baseline to post-baseline will be tested using the McNemar's test. Baseline, Wee4 and Week 8
Other Electrocardiogram (ECG) For each ECG parameters at baseline and post-baseline, the shift table will be presented with frequency and percentage. The difference in the percentage of subjects whose ECG results changed from 'clinically insignificant' to 'clinically significant' between treatment arms will be tested using the ?2 test or Fisher's exact test. The intra-arm change from baseline to post-baseline will be tested using the McNemar's test. Screening and Week 8
Primary Change in sitting Systolic Blood Pressure(siSBP) from baseline after 8 weeks of treatment For change in siSBP from baseline after 8 weeks of treatment, the mean, standard deviation, median, minimum and maximum will be presented by treatment arm.
The LS mean change in siSBP from baseline after 8 weeks of treatment adjusted for baseline siSBP and its standard error will be presented by treatment arm. Non-inferiority test will be conducted using ANCOVA including change in siSBP from baseline after 8 weeks of treatment as response variable and baseline siSBP and treatment arm as independent variables. Amlodipine besylate/candesartan cilexetil combination tablet will be considered non-inferior to co-administration of amlodipine besylate and candesartan cilexetil if the lower bound of 2-sided 95% CI for the LS mean of difference in siSBP change between the treatment arms is greater than -5.
Week 8
Secondary Change in siSBP from baseline after 4 weeks of treatment For change in siSBP from baseline after 4 weeks of treatment, the mean, standard deviation, median, minimum and maximum will be presented by treatment arm.
The LS mean change in siSBP from baseline after 4 weeks of treatment adjusted for baseline siSBP and its standard error will be presented by treatment arm. Non-inferiority test will be conducted using ANCOVA including change in siSBP from baseline after 4 weeks of treatment as response variable and baseline siSBP and treatment arm as independent variables. Amlodipine besylate/candesartan cilexetil combination tablet will be considered non-inferior to co-administration of amlodipine besylate and candesartan cilexetil if the lower bound of 2-sided 95% CI for the LS mean of difference in siSBP change between the treatment arms is greater than -5.
Week 4
Secondary Change in siDBP from baseline after 4 and 8 weeks of treatment For change in siDBP from baseline after 4 and 8 weeks of treatment, the mean, standard deviation, median, minimum and maximum will be presented by treatment arm.
The LS mean change in siSBP from baseline after 4 and 8 weeks of treatment adjusted for baseline siDBP and its standard error will be presented by treatment arm. Non-inferiority test will be conducted using ANCOVA including change in siDBP from baseline after 4 and 8 weeks of treatment as response variable and baseline siDBP and treatment arm as independent variables. Amlodipine besylate/candesartan cilexetil combination tablet will be considered non-inferior to co-administration of amlodipine besylate and candesartan cilexetil if the lower bound of 2-sided 95% CI for the LS mean of difference in siSBP change between the treatment arms is greater than -5.
Week 4 and Week 8
Secondary Proportion of subjects with siDBP < 90 mmHg and siSBP <140 mmHg after 8 weeks of treatment The frequency and percentage of subjects with siDBP < 90 mmHg and the frequency and percentage of subjects with siSBP < 140 mmHg after 8 weeks of treatment will be presented by treatment arm. Additionally, the frequency and percentage of subjects with both siDBP < 90 mmHg and siSBP <140 mmHg after 8 weeks of treatment will be presented by treatment arm.
