Lowering Blood Pressure in Primary Care in Vienna

Status Completed

Clinical Trial Summary

The aim of this prospective, randomised, open-label, multicentre clinical trial is to enhance blood pressure control in primary care by introducing a standardised and simplified titration regime with single pill combinations (SPC), comprising an angiotensin receptor blocker, calcium channel blocker and hydrochlorothiazide.

Clinical Trial Description

Rationale Hypertension is the single largest contributor to mortality worldwide, accounting for 13% of deaths globally. Approximately 30% of the adult population suffer from hypertension and of those diagnosed and treated, only 30-50% have adequately controlled blood pressure. At present, the importance of hypertension as fundamental risk factors is inadequately addressed among many patients and physicians.

Design The aim of this prospective, randomised, open-label, multicentre clinical trial is to enhance blood pressure control in primary care by introducing a standardised and simplified titration regime with single pill combinations (SPC), comprising an angiotensin receptor blocker, calcium channel blocker and hydrochlorothiazide.

The trial will randomise 42 family doctors or resident specialists for internal medicine (enrolling 840 patients with treated or untreated hypertension) to either experimental care or standard care for hypertension, latter according to the 2013 European Society of Cardiology Guidelines for the Management of Arterial Hypertension.

Practitioners randomised to experimental care will up-titrate antihypertensive therapy with SPCs in 4-week intervals if the target blood pressure of < 140/90 mmHg is not reached at the respective follow-up (Figure 1).

Study Outcomes The primary efficacy endpoint will be the proportion of patients achieving the target office blood pressure after 6 months of follow-up. The main secondary endpoint will be the improvement of 24h ambulatory blood pressure (ABPM) profile, measured at inclusion and after 6 months of follow-up.

Safety assessments include the evaluation of treatment emergent adverse events, particularly hospitalisation, worsening of renal function, peripheral oedema and hypotension. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
