NCT01157234

Brief Summary

This study will investigate the blood pressure lowering efficacy of nebivolol among renal transplant recipients who are on calcineurin inhibitors which are believed to contribute to hypertension by sympathetic nervous system (SNS) activation and decreased prostaglandin and nitric oxide production. Hypotheses:

  1. 1.There is a significant difference in the effect of 12 months of Nebivolol versus Metoprolol treatment on the plasma nitric oxide level of hypertensive renal transplant patients.
  2. 2.There is a significant difference in the effect of 12 months of Nebivolol versus Metoprolol treatment on the estimated glomerular filtration rate of hypertensive renal transplant patients.
  3. 3.There is a significant difference in the effect of 12 months of Nebivolol versus Metoprolol treatment on the systolic, diastolic and mean arterial blood pressures of hypertensive renal transplant patients.

Outcome Measures

Primary Outcomes (1)

  • Plasma Nitric Oxide Level Change From Baseline to Month 12 Between the Groups.

    Percent change in Nitric Oxide (NO) blood level (nmol/L)=\[Month-12 NO blood level minus baseline NO blood level\] divided by \[baseline NO blood level\] multiplied by 100, where all levels are in nmol/L.

    Change in Baseline, Month-12

Secondary Outcomes (7)

  • Estimated Glomerular Filtration Rate (ml/Minute) Change From Baseline to Month-12 Between the Groups

    Change in Baseline, Month-12

  • Systolic Blood Pressure (Millimeter, Mercury) Change From Baseline to Month-12 of Treatment Between the Groups

    Change in Baseline, Month-12

  • Diastolic Blood Pressure (Millimeter, Mercury) Change From Baseline to Month-12 Between the Groups

    Change in Baseline, Month-12

  • Mean Arterial Blood Pressure (Millimeter, Mercury) Change From Baseline to Month-12 Between the Groups

    Change in Baseline, Month-12

  • Number of Antihypertensive Drug Classes Change From Baseline to Month-12 Between the Groups.

Other Outcomes (1)

  • Plasma Nitric Oxide Level (Nmol/L) at Month-12 Between the Groups.

    12 Months

Study Arms (2)

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo

  • Current diagnosis of hypertension
  • Normal hepatic enzymes
  • Estimated creatinine clearance (by cockcroft-gault formula) \>or= 30 ml/min

You may not qualify if:

  • Any contraindication to taking beta-blockers, specifically Nebivolol or Metoprolol. Conditions such as : (bradycardia heart rate (HR) \<60 beats per minute , heart block \> 1st degree, decompensated cardiac failure, sick sinus syndrome (unless permanent pacemaker in place), severe hepatic impairment( defined as elevation of aspartamine aminotransferase , alanine aminotransferase, or bilirubin levels to three times upper limit of normal reference range), severe peripheral arterial circulatory disorder, history of bronchospasm and /or asthma and /or regular medication with inhaled bronchodilators. or , or any medical condition that in the opinion of the investigator may interfere with the subject's ability to successfully complete the protocol.
  • Any medical condition which, in the opinion of the Principal Investigator, might compromise the safety of the subject in participating in the protocol such as hypotension or not requiring antihypertensive medications.
  • Any serious systemic disease that might complicate management and reduce life expectancy.
  • Uncontrolled hypertension defined as systolic blood pressure (SBP) \> 210 or diastolic blood pressure (DBP) \> 120 mm Hg.
  • Symptomatic hypotension
  • Previous intolerance to beta blockers
  • Cerebrovascular accident within 3 months of randomization

Limitations and Caveats

Small numbers of subjects analyzed in a single center limits precision and generalizability of results. Technical limitations prevented measurements of asymmetric dimethyl-arginine and arginine leading to absence of analysis for these outcomes.
