ClinicalTrials.gov Identifier: NCT00637078
  Purpose

The objective of this study is to assess if the implementation of a treatment algorithm including initial treatment with a low dose diuretic/ACE-inhibitor or ARB combination and subsequently a low dose DHP-CCB/statin combination will improve the management of hypertension/hypercholesterolemia compared to guidelines-base management at family practices.


Condition Intervention Phase
Hypertension
Hypercholesterolemia

Study Type: Interventional
Study Design: Treatment, Randomized, Open Label, Active Control, Parallel Assignment, Efficacy Study
Official Title: Evaluation of a Primary Treatment Algorithm Using Combination Therapy for the Management of Patients With Hypertension and Hypercholesterolemia

Further study details as provided by Robarts Research Institute:

Primary Outcome Measures:
  • Proportion of subjects whose systolic BP [SBP] <140 mmHg and diastolic BP [DBP] <90 mmHg)or proportion whose cholesterol levels are at or below threshold based on their global artherosclerotic risk profile compared at the practice level. [ Time Frame: 6 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Secondary measures include the change at 6 months in SBP and DBP and cholesterol levels. These outcomes will be compared at the practice level [ Time Frame: 6 months ] [ Designated as safety issue: No ]

Estimated Enrollment: 2500
Study Start Date: February 2008
Estimated Study Completion Date: March 2010
Estimated Primary Completion Date: October 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
1: Active Comparator
Drug: Fix dose combination therapy
Other: Treatment algorithm:caduet, Amlodipine, ACEI-ARB combo dose, a-blocker, b-blocker or spironolactone, dyslipidemic therapy with ezetamide
initial treatment with a low dose diuretic/ACE-inhibitor or ARB combination followed by a low dose DHP-CCB/statin combination
2: No Intervention
Guidelines based management

Detailed Description:

Utilization of fixed dose combination therapy has been advocated as an adherence-enhancing strategy and has been so recommended in the 2007 Canadian Hypertension Education Program (CHEP) recommendations. Further, in a previous study (STITCH) it was demonstrated that a simplified treatment algorithm utilizing initial therapy with a low dose fixed-dose combination therapy improved blood pressure control in hypertensive patients. However, the effectiveness of either a simplified treatment algorithm or the initial use of fixed dose combination therapies for 2 risk factors in hypertensive dyslipidemic patients has yet to be determined. Therefore, the current study is designed to determine whether utilization of a fixed dose combination hypertension/hypercholesterolemia therapy results in improved adherence, patient satisfaction as well as improved rates of reaching target LDL cholesterol and blood pressure.
