An Open Label, Pharmacogenetic Study of Bisoprolol Treatment in Patients With Uncontrolled Essential Hypertension (BRAVE)

Detailed Summary

This is an open-label, placebo run-in study to investigate the genetic and biomedical predictors of blood pressure response to bisoprolol. After informed consent is obtained, subjects will be withdrawn from previous antihypertensive therapy and given placebo for at least 2 weeks. Compliance will be assessed using pill counting, and any subject will a compliance less than 80% during the placebo run-in period will be excluded from the study. Bisoprolol 2.5 mg will be given once daily for 6 weeks. At baseline and after 6 weeks on bisoprolol 2.5 mg the clinic sitting blood pressure, 24-hour ambulatory blood pressure (if the patient is willing to do this), clinical characteristics and biochemical profile will be measured. Central aortic blood pressure will be measured with the A-PULSE device at baseline and after 6 weeks treatment. After completing 6 weeks treatment with bisoprolol 2.5 mg daily, the patient will continue treatment with bisoprolol for a total of 24 weeks unless there is any adverse event that requires discontinuation of bisoprolol.
