About

This study examines the long term safety and efficacy of the Fixed Dose combination BAY98-7106 (nifedipine plus candesartan primarily at the highest dose in development) in patients with moderate to severe hypertension. Patients meeting the entry criteria, will receive the Fixed Dose combination for 28 weeks, including 8 weeks with stepwise dose increase up to the high target dose. The first 200 subjects completing 28 weeks will continue treatment for additional 24 weeks (52 weeks in total). Subjects who do not tolerate an increased dose will be treated at their highest tolerable dose.

Inclusion criteria

  • Subjects must have moderate to severe essential hypertension (Grade 2 or Grade 3, WHO classifications). At Visit 1, subjects not treated with antihypertensive medications are to have MSSBP of >/= 160 mmHg and < 200 mmHg, as measured by a calibrated electronic BP measuring device. For other subjects who are treated with antihypertensive medication before, they should have MSSBP >/= 160 mmHg and <200 mmHg after wash out.
  • Women of childbearing potential and men must agree to use adequate contraception other than hormonal contraceptives when sexually active

Exclusion criteria

  • Mean seated systolic blood pressure >/= 200 mmHg and/or mean seated diastolic blood pressure >/= 120 mm/Hg
  • Mean seated diastolic blood pressure < 60 mm/Hg
  • Differences greater than 20 mmHg for systolic blood pressure and 10 mmHg for diastolic blood pressure are present on 3 consecutive blood pressure readings at visit 0
  • Any history of hypertensive emergency
  • Evidence of secondary hypertension such as coarctation of the aorta, pheochromocytoma, hyperaldosteronism, etc.
  • Cerebrovascular ischemic event (stroke, transient ischemic attack [TIA])within the previous 12 months
  • History of intracerebral hemorrhage or subarachnoid hemorrhage
  • History of hypertensive retinopathy - known Keith-Wagener Grade III or IV
  • Any history of heart failure, New York Heart Association (NYHA) classification III or IV
  • Severe coronary heart disease as manifest by a history of myocardial infarction or unstable angina in the last 6 months prior to visit 0
  • Type 1 diabetes mellitus (DM) or poorly controlled Type 2 DM as evidenced by HbA1C of greater than 9% on visit 0.
  • Hyperkalemia: potassium above the upper limit of normal in the laboratory range

Experimental group
Description:
Subjects received nifedipine gastrointestinal therapeutic system (GITS) / candesartan cilexetil fixed dose combination (FDC) (BAY98-7106) tablet orally, once daily in the morning of Visit 1 (Week 0) for 28 or 52 weeks. The starting dose (30/8 milligram [mg] or 30/16 mg) was determined based on local practice and clinical judgment by the investigator. Based on the experience of symptomatic and asymptomatic hypotension, peripheral edema or significant tolerability, the doses were up-titrated to the highest target dose (60/32 mg).
Treatment:
Drug: Nifedipine GITS/Candesartan Cilexetil FDC(BAY98-7106)
