Condition(s) targeted: Hypertension

Intervention: Valsartan, hydrochlorothiazide and amlodipine (Drug)

Phase: Phase 4

Status: Completed

Sponsored by: Novartis

Official(s) and/or principal investigator(s):
Novartis AG, Study Chair, Affiliation: Sponsor GmbH

Summary

This study is designed to evaluate the efficacy and safety of the combination valsartan with hydrochlorothiazide and amlodipine in hypertensive patients previously treated with valsartan with hydrochlorothiazide and remaining uncontrolled. A naturalistic approach will be taken comparing two different possible ways to achieve the higher dosage of the triple combination, i. e. 160 mg of valsartan and 25 mg of hydrochlorothiazide with amlodipine 10 mg.

Clinical Details

Official title: An Open-Label, Randomized, Multicenter Study to Evaluate the Efficacy of the Combination of Valsartan and Hydrochlorothiazide and Amlodipine in Hypertensive Patients Not Controlled With Valsartan and Hydrochlorothiazide

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: Proportion of patients reaching diastolic BP control, Proportion of patients reaching systolic BP control Percentage of diastolic responders,

Secondary outcome:

Mean change from study baseline in Diastolic Blood Pressure and in Systolic Blood Pressure after 4, 8 and 12 weeks of treatment

Mean change from study baseline in standing diastolic and systolic blood pressure after 4, 8 and 12 weeks of treatment

Safety and tolerability of the valsartan/HCTZ/amlodipine treatment algorithm strategy after 4, 8 and 12 weeks of treatment
