ClinicalTrials.gov Identifier:	NCT00142584

Purpose

The purpose of this study is to evaluate long-term safety,tolerability and blood pressure effects of metoprolol versus nebivolol in patients with hypertension. These drugs may be given alone or in combination with other drugs that are commonly used in the treatment of hypertension

Primary Outcome Measures:

Change in average sitting DBP taken at trough at the end of treatment compared to baseline (baseline is defined as the baseline of the feeder study). [ Time Frame: During study. ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

SBP, pulse pressure and heart rate at peak and trough drug effects measured in the supine, sitting and standing positions. [ Time Frame: During study. ] [ Designated as safety issue: No ]
Adverse events, ECGs, laboratory evaluations [ Time Frame: During study. ] [ Designated as safety issue: No ]

Estimated Enrollment:	1000
Study Start Date:	August 2005
Study Completion Date:	March 2008
Estimated Primary Completion Date:	March 2008 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
1-NEB: Experimental Nebivolol	Drug: Nebivolol Patients randomized to nebivolol will initiate therapy with nebivolol 5 mg once daily for 4 weeks.
2-MET: Active Comparator Metoprolol	Drug: Metoprolol Patients randomized to metoprolol will initiate therapy with 100 mg once daily for 4 weeks.

Detailed Description:

Approximately 50 million Americans have hypertension defined as a systolic blood pressure (SBP) greater then or equal to 140 mmHg and/or a diastolic blood pressure (DBP) greater then or equal to 90 mmHg. To control blood pressure, more than 2 agents are required in many patients. The current study is a randomized, titration-to-effect, open-label, multi center study. Patients will be randomized to either nebivolol or metoprolol. The dose of the randomized treatment can be titrated as needed to achieve blood pressure control. If necessary, additional antihypertensive agents (calcium antagonist, diuretic, etc.) can be added to achieve control. Patients will be seen every 1-3 months for approximately 18 months to assess long-term safety, tolerability and effectiveness of nebivolol versus metoprolol.
