Study to Confirm the Efficacy and Safety of Fixed-dose Combinations of Amlodipine and Candesartan (MACH)

15 octobre 2018 mis à jour par: HK inno.N Corporation

A Randomized, Double-blind, Multi-center, Phase Ⅳ Clinical Trial to Evaluate the Antihypertensive Efficacy and Safety Between Amlodipine Besylate/Candesartan Cilexetil Combination Tablets and Co-administration of Amlodipine Besylate and Candesartan Cilexetil in Patients With Essential Hypertension

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

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.
