Efficacy and Safety of Valsartan Plus Hydrochlorothiazide in Fixed Dose Combination in Hypertensive Patients Not Controlled by the Free Combination of an Angiotensin Receptor Blocker Plus Hydrochlorothiazide - Full Text View

Sponsor:	Novartis
Information provided by:	Novartis
ClinicalTrials.gov Identifier:	NCT00360178

Purpose

Recruiting in Germany only:

This study will evaluate the safety and efficacy of valsartan plus HCTZ in fixed dose combination in hypertensive patients not responding to treatment with the free combination of Candesartan plus HCTZ. In an optional extension patients with uncontrolled BP at the end of the core study can be treated with valsartan plus HCTZ in fixed dose combination plus amlodipine 5 mg for additional 4 weeks.

Further study details as provided by Novartis:

Primary Outcome Measures:

Diastolic Blood Pressure (DBP) reduction by Valsartan + HCTZ in patients not adequately responding (i.e., DBP >= 90 mmHg) to 4 weeks of treatment with Candesartan + HCTZ in free combination
For optional extension: DBP reduction by Valsartan + HCTZ + Amlodipine in patients not adequately responding (i.e., DBP >= 90 mmHg and/or Systolic Blood Pressure (SBP) >= 140 mmHg) to 4 weeks of treatment with angiotensin receptor blockers + HCTZ

Secondary Outcome Measures:

SBP, pulse pressure, heart rate, normalization (DBP < 90 mmHg and/or SBP < 140 mmHg, resp.)and responder rate(DBP < 90 mmHg or reduction by at least 10 mmHg and/or SBP < 140 mmHg or reduction by at least 20 mmHg, rep)
Safety and tolerability
Compliance by pill count
For optional extension: SBP, pulse pressure, heart rate, normalization and responder rate as defined above

Estimated Enrollment:	220
Study Start Date:	July 2006
