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

November 16, 2016 updated by: Novartis

An Open-label, Multicenter Study to Evaluate the Efficacy and Tolerability of a 4 Week Therapy With the Fixed Dose Combination of Valsartan 160 mg Plus HCTZ 25 mg in Hypertensive Patients Not Adequately Responding to a 4 Week Therapy With the Free Combination of an Angiotensin Receptor Blocker (Candesartan 32 mg) Plus HCTZ 25 mg

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
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

Outcome Measure
Safety and tolerability
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)
Compliance by pill count
For optional extension: SBP, pulse pressure, heart rate, normalization and responder rate as defined above
