简要总结

The purpose of this study is to evaluate the efficacy and safety of TCV-116CCB (candesartan cilexetil and amlodipine besylate fixed-dose combination) in Chinese participants with mild to moderate hypertension who do not reach target blood pressure following 4 weeks of treatment with amlodipine monotherapy.

详细描述

The drug being tested in this study is called TCV-116CCB (candesartan cilexetil and amlodipine besylate fixed-dose combination). This study will look at blood pressure in Chinese participants with grade 1 or 2 essential hypertension.

The study will enroll approximately 370 patients. Prior to the start of study treatment, participants will undergo run-in period of 2 weeks followed by single-blind treatment period of 4 weeks. Upon completion of single-blind treatment period, participants will be randomly assigned (by chance, like flipping a coin) to one of the two treatment groups-which will remain undisclosed to the participant and study doctor during the study (unless there is an urgent medical need):

Amlodipine 5 mg
TCV-116CCB (Candesartan 8 mg Plus Amlodipine 5 mg)

All participants will be asked to take one tablet/capsule at the same time each day throughout the study up to 8 weeks.

This multicenter trial will be conducted China. The overall time to participate in this study is 19 weeks. Participants will make multiple visits to the clinic, and will be contacted by telephone plus a final visit 14 days after receiving their last dose of drug for a follow-up assessment.

•Is willing to discontinue current antihypertensive medications.
•Entering amlodipine 5 mg monotherapy:
•Must have a clinic SBP measurement of 155 to 179 mm Hg inclusive (determined by the mean of 3 sitting, trough, measurements on Day -28, using same arm throughout study) to qualify for entry in to the 4 week single-blind amlodipine 5 mg monotherapy treatment period.
•At double-blind randomization:
•Has not achieved target blood pressure (defined as clinic SBP ≥140 mm Hg as determined by the mean of 3 sitting, trough, measurements) following 4 weeks single-blind treatment with amlodipine 5 mg monotherapy at Day 1 prior to randomization to double-blind treatment.

排除标准

•Post-single-blind amlodipine 5 mg treatment period:
•Achieves target blood pressure (defined as clinic SBP<140 mm Hg as determined by the mean of 3 sitting, trough measurements) following 4 weeks single-blind treatment with amlodipine 5 mg monotherapy at Day 1, prior to randomization to double-blind treatment.
•Has a clinic SBP ≥180 mm Hg or/and DBP ≥110 mm Hg.
•Is non-compliant (<80% or >120%) with study medication during the amlodipine 5 mg single-blind treatment period.
