简要总结
This study will evaluate the safety and efficacy of a new combination of 3 (three) antihypertensive drugs in a single pill (candesartan cilexetil 16mg + chlorthalidone 12.5mg + amlodipine 5mg) compared with another combination of 3 (three) antihypertensive drugs (Exforge HCT® [valsartan 160mg + hydrochlorothiazide 12.5mg + amlodipine 5mg]). This will be a non-inferiority trial and the primary outcome will be blood pressure control after 12 weeks of treatment.
详细描述
This phase III, multicenter, randomized, double-blind, controlled, parallel trial will evaluate the non-inferiority of the association between candesartan cilexetil 16mg + chlorthalidone 12.5mg + amlodipine 5mg in relation to Exforge HCT® (valsartan 160mg + hydrochlorothiazide 12 5mg + amlodipine 5mg) in the treatment of systemic arterial hypertension. A total of 698 participants will be included. Follow-up visits will occur four, eight, and twelve weeks after the date of the randomization visit. A telephone contact will be performed 30 days after the end of treatment. The primary efficacy outcome is the mean change in blood pressure, measured at the research site, 12 weeks after starting treatment, compared to baseline. Incidence of adverse events will be collected from the first dose of treatment up to 30 days after the end of the treatment foreseen in the protocol.

盲法说明
The experimental/comparator drug has different characteristics. To allow blinding, the Double-Dummy method will be performed, where study sites will receive two drug presentations (active and placebo), thus preventing any violation of blinding.
