    Control rate is the percentage of subjects that reach the predetermined blood pressure (BP) target < 140/90 mmHg. In addition, the percentage of subjects that reach the predetermined BP target will be provided as well (BP < 140/90 mmHg for subjects without diabetes and chronic renal disorder, and BP <130/80 mmHg for subjects with diabetes or chronic renal disorder).
  • Blood pressure Control Rate [ Time Frame: Week 52 ] [ Designated as safety issue: No ]
    Control rate is the percentage of subjects that reach the predetermined blood pressure (BP) target < 140/90 mmHg. In addition, the percentage of subjects that reach the predetermined BP target will be provided as well (BP < 140/90 mmHg for subjects without diabetes and chronic renal disorder, and BP <130/80 mmHg for subjects with diabetes or chronic renal disorder).

Open-Label Long-Term Safety and Efficacy Study of Fixed Dose Combination of Nifedipine Gastrointestinal Therapeutic System and Candesartan Cilexetil in Subjects With Moderate to Severe Essential Hypertension
Multicenter, Open-Label, Long-Term Safety and Efficacy Study of the Fixed Dose Combination of Nifedipine Gastrointestinal Therapeutic System and Candesartan Cilexetil in Adult Subjects With Moderate to Severe Essential Hypertension

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.

Experimental: Nifedipine GITS/Candesartan Cilexetil FDC (BAY98-7106)
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).
